But just because ‘Oumuamua was the first detected interstellar object, doesn’t mean it was the first ever. Just five years ago, in fact, Earth’s atmosphere was struck by something that may have originated far outside our own Solar System – and we never even realised it.
In a new paper, a pair of Harvard researchers propose that a meteor that collided with Earth’s atmosphere in January 2014 was actually another interstellar traveller with distant, mysterious origins.
But unlike the hurtling ‘Oumuamua – which is on a 20,000-year trajectory that will see it eventually exit our Solar System – this meteor’s long journey was fated to be a one-way ticket, ending with a fiery finale five years ago, as the object burnt up in the skies above Papua New Guinea.
“Instead of looking far out into space, and given the fact that there should be a higher abundance of interstellar objects smaller than ‘Oumuamua, we thought, ‘Why not look locally and find these smaller interstellar objects as they collide with the Earth’s atmosphere?'” first author, astronomer Amir Siraj told Newsweek.
Hidden in the CNEOS data, there lurked a remarkable outlier: a 2014 fireball that rushed Earthwards at a velocity of around 60 kilometres per second (37 mps) as it passed the Sun.
We can be grateful that this object was quite small – less than a metre across in total – because if it were significantly larger, it could have made for a disastrous impact with Earth’s surface, rather than the harmless atmospheric fizzle that eventuated.
But that happy anti-climax isn’t the primary takeaway of the meteor’s blistering speed.
When Siraj and Loeb calculated the meteor’s orbital trajectory based on its velocity, their numbers suggested the object wasn’t orbitally bound to the Sun: it was travelling so fast before its fiery end, it slipped straight through the Sun’s gravitational pull.
For that to be possible, the researchers suggest, the meteor had to originate from somewhere else, far beyond our Solar System.
Per their calculations, the meteor’s speed “implies a possible origin from the deep interior of a planetary system or a star in the thick disk of the Milky Way galaxy”.
It’s a wild idea, but while the findings remain purely hypothetical for now, Siraj and Loeb’s paper – which has not yet been peer-reviewed – has been welcomed by some in the astronomy community.
“I think it is reasonable to conclude that this very high speed impactor came from the population of interstellar objects,” theoretical astrophysicist Kat Volk from the University of Arizona, who wasn’t involved with the study, told National Geographic.
“I expect interstellar objects to be common enough – both from theoretical considerations and from the implications of ‘Oumuamua – that I think an interstellar origin is the simplest explanation for this bolide.”
But while ‘Oumuamua’s discovery has definitely shifted the landscape, helping to make real the previously theoretical underpinnings of interstellar migrations, not everybody is yet convinced that this 2014 bolide held such a fantastic passport.
“The result is interesting, but rests upon measurements for a single event,” astronomer Eric Mamajek from NASA’s Jet Propulsion Laboratory told Science News.
“Was the event a statistical fluke or an actual interstellar meteor?”
The jury is still out on that one, but the hypothetical possibilities in this area of science are as beguiling as an invitation to trek beyond the stars.
Per Siraj and Loeb’s calculations, these interstellar bolide events would have already occurred countless times in Earth’s history, and by looking out for future visits, we could learn much about these distant travellers’ backgrounds.
“Future meteor surveys could flag incoming objects with excess heliocentric velocities for follow-up pre-impact observations,” the researchers write.
“Spectroscopy of gaseous debris from these objects as they burn up in the Earth’s atmosphere would reveal their composition… Potentially, interstellar meteors could deliver life from another planetary system and mediate panspermia.”
Any way you look at it, amazing things are coming our way.
The findings are available on the pre-print website arXiv, and have been submitted to the Astrophysical Journal Letters.
It was the first molecule to form after the Big Bang.
A flying observatory has pinpointed the first type of molecule that formed in the universe after the Big Bang.
Helium hydride — a combination of helium and hydrogen — was detected roughly 3,000 light-years from Earth by NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA). The molecule was found in a planetary nebula, NGC 7027, which is the dusty remnant of a sun-like star.
For hundreds of thousands of years after the Big Bang, the universe was too hot and too full of radiation for atoms to bond together. At that time, only a few types of atoms existed, including hydrogen, helium and lithium. However, the new study shows that 100,000 years after the Big Bang, the universe cooled enough for helium and hydrogen to combine, forming the molecule known as helium hydride.
While helium hydride has been produced and tested in a laboratory setting, this discovery marks the first time that the molecule has been detected in space — which sheds light on the chemistry of the early universe, according to a statement from NASA.
“This molecule was lurking out there, but we needed the right instruments making observations in the right position — and SOFIA was able to do that perfectly,” Harold Yorke, director of the SOFIA Science Center in California’s Silicon Valley, said in the statement.
Once the universe cooled down, hydrogen atoms started to interact with helium hydride, creating molecular hydrogen, which set the stage for star formation. From that point on, stars created the other elements of the cosmos, according to the statement.
“The lack of evidence of the very existence of helium hydride in interstellar space was a dilemma for astronomy for decades,” Rolf Guesten, lead author of the study from the Max Planck Institute for Radio Astronomy in Bonn, Germany, said in the statement.
NGC 7027 has been a location of interest for helium hydride since the late 1970s. Ultraviolet radiation and heat from the aging star led scientists to believe that its environment would be suitable for helium hydride to form. However, astronomers were unable to confirm this theory until now.
The SOFIA instrument is a telescope that is flown on a Boeing 747-SP airplane at up to 45,000 feet, where its observations are not impacted by interference from Earth’s atmosphere. SOFIA returns to Earth after every flight, allowing scientists to regularly update the instrument with the latest technology. One of the most recent upgrades included adding a specific channel to detect signatures of helium hydride, which previous telescopes did not have.
“This flexibility allows us to improve observations and respond to the most pressing questions that scientists want answered,” Naseem Rangwala, SOFIA deputy project scientist, said in the statement.
A preliminary investigation into what caused Israel’s Beresheet spacecraft to crash-land on the moon April 11 puts the apparent blame on a “manual command” that was entered into the spacecraft’s computer.
“This led to a chain reaction in the spacecraft, during which the main engine switched off, which prevented it from activating further,” according to a statement released today (April 17) by Beresheet’s handlers, the nonprofit group SpaceIL and the company Israel Aerospace Industries (IAI).
Teams continue to investigate further, in order to understand the full picture of what occurred during the mission, the statement says. “In the coming weeks, final results of the investigation will be released.”
Meanwhile, researchers are on the lookout for a NASA piggyback experiment that may have survived Beresheet’s destructive April 11 crash landing.
NASA’s Lunar Reconnaissance Orbiter (LRO) will target the crash site repeatedly, eyeing the area with its high-powered cameras. In addition, LRO will use its onboard Lunar Orbiter Laser Altimeter (LOLA) in an attempt to detect a NASA-provided laser retro-reflector array in the Beresheet wreckage zone.
The size of a computer mouse, LRA is composed of eight mirrors made of quartz cube corners that are set into a dome-shaped aluminum frame. That array is lightweight, radiation-hardened and long-lived.
From the high-flying LRO, laser beams generated by LOLA would strike the device and then bounce back to the orbiter. For each laser beam, LOLA measures its time of flight, or range.SpaceIL’s Beresheet Took Selfie Minutes Before Crashing Into MoonVolume 0%
While there will be many attempts to target the wreckage, LRO is directly over the site only twice per month, and one of those passes occurs in darkness (which is not an issue for the laser), explained the Massachusetts Institute of Technology’s David Smith, the principal investigator for LOLA and an emeritus researcher at NASA Goddard in Greenbelt, Maryland.
“But the site can be viewed on several passes around the ‘overhead’ pass by looking off to the side or forward or backward. This requires the spacecraft to slew or roll to see the target,” Smith said.
“That’s a decision that LRO makes to ensure there are no issues with regard to constraints on pointing close to the sun or star cameras being able to see the stars (and not the lunar surface),” he added., So, the process requires requests for slew and role magnitudes and directions to the LRO project for a specific observation time.‘Return to the Moon: Seconds to Arrival’ – Science Channel ClipVolume 0%
This is normal procedure, Smith said, but typically researchers need to submit pointing requests about a week in advance. That allows the LRO project to check on pointing abilities (there are limits) of LRO and on thermal effects and spacecraft solar array pointing for charging the batteries.
“It may take 10 to 15 minutes for the spacecraft to turn to the desired direction and another 15 minutes to return to its normal nadir mode for just a few seconds of observations,” Smith told Inside Outer Space.
“I am sure the project will start to attempt observations as soon as possible,” Smith said. LRO’s camera system and the laser are co-boresighted, “so when the camera slews to take an image, the laser altimeter automatically goes with it and will attempt to make a range observation at the same time.”
At a speed of over 3,300 mph (5,310 km/h), the whole LRO observation period is over in a few seconds, Smith said.

The Facts:A document published by Wikileaks clearly implies that the United States had a “secret” base on the Moon that was destroyed by Russia. It’s one of many interesting documents that suggest strange things are and have been happening on the Moon.
Reflect On:Is our world really as it’s been presented? There are millions of pages of documents that are classified by multiple countries every single year, how is it possible to really determine what’s going on behind the scenes? Why does secrecy rule?
The Assange arrest is scandalous in several respects, and one of them is the effort of governments, and it’s not just the US government… The efforts to silence a journalist who was producing materials that people in power didn’t want the rascal multitude to know about… That’s basically what happened. Wikileaks was producing things that people ought to know about those in power, people in power don’t like that. So therefore we have to silence it. – Noam Chomsky (source) advertisement – learn more
The idea that something strange may be happening on the Moon is not far fetched at all. In fact, given all of the information that’s now available within the public domain on the subject, it’s hard to see how it’s not a fact. We’ll get to some of that information later in this article; but first, let’s draw our attention to a strange Wikileaks document titled, “Report That UR Destroyed Secret Moon Base.”
Unfortunately, the document is not an electronic document, therefore access to its full contents is not available online. For anybody truly interested in reading the entire thing, a Freedom of Information Act Request (FOIA) may be in order.
Without speculating here, we can conclude that this is what it says it is, a report regarding possible space wars that are taking place in the classified world. The document title alone not only exposes the reality of these alleged wars, but the possibility of a “Secret Moon Base” belonging to the United States that apparently was in operation until it was destroyed by “UR.” (Soviet Union)
You can view it in the Wikileaks archive here. advertisement – learn more
So, what other information exists, besides this document, showing that something strange is and has been happening on the Moon? There’s a lot of information, so it’s hard to know where to begin.
First of all, the idea of bases on the Moon have been an open discussion within the government for a long time, although the information isn’t easy to find, but it’s definitely out there. A document from the government’s own publishing office is a great example. It clearly shows one of the goals of the United States government is to build a base on the Moon, and this is as far back as 1966. (source)
A portion of the document reads, with reference to presidents Kennedy and Johnson in a statement by HON. George P. Miller:
I also believe that we can and will achieve the goal set by Presidents Kennedy and Johnson: a manned landing on the moon before 1970. My own confidence in our rapidly advancing science and technology is such that I can visualize many more dramatic achievements ahead, although I will fix no timetable for them. 1. The exploration of the lunar surface, and possibly the establishment of one or more permanent bases there.
Furthermore, decades old documents have been declassified discussing this topic, showing just how serious and far possible advancements with these intentions have gone.
Take a look at the screen shot below, taken from the CIA electronic reading room in the form of a memorandum that was addressed to the CIA director regarding “Military Thought (Top Secret)” by Lieutenant General Korenevskiy.

The document above really goes into detail regarding the importance of weaponizing space. This brings to mind another document from Wikileaks, in the form of an email that was sent to politician John Podesta from Dr. Edgar Mitchell, Apollo 14 astronaut, and Dr. Carol Rosin. It reads as follows:
Dear John, Because the War in Space race is heating up, I felt you should be aware of several factors as you and I schedule our Skype talk. Remember, our nonviolent ETI from the contiguous universe are helping us bring zero point energy to Earth. They will not tolerate any forms of military violence on Earth or in space. The following information in italics was shared with me by my colleague Carol Rosin, who worked closely for several years with Wernher von Braun before his death. Carol and I have worked on the Treaty on the Prevention of the Placement of Weapons in Outer Space, attached for your convenience.
A declassified report by the Air Force Nuclear Weapons Center from June 1959 shows just how seriously they considered a plan called Project A119. In general, they wanted to investigate the capability of weapons in space as well as gain further insight into the space environment and the detonation of nuclear devices within it.
Interesting to say the least, but it’s important to recognize the intentions behind the letter, and that is the recognition that humans have brought and will continue to bring their destructive ways into space by weaponizing it or attempting to weaponize it.
With all of this documentation, it’s also interesting to look into witness testimonies from credible sources.
In the 1950s, Colonel Ross Dedrickson was responsible for maintaining the inventory of the nuclear weapon stockpile for the AEC, and for accompanying security teams testing the security of the weapons, among many other duties. When it comes to weaponizing space, which is clearly outlined within multiple documents linked above, this is what he had to say:
“I also learned about incidents involving nuclear weapons, and among these incidents were a couple of nuclear weapons sent into space that were destroyed by the extraterrestrials… At the very end of the 70s and the early 80s, we attempted to put a nuclear weapon on the Moon and explode it for scientific measurements and other things, which was not acceptable to the extraterrestrials. They destroyed the weapon before it got to the Moon.” (source)
Dedrickson is one of hundreds of whistleblowers with verified, credible and impressive backgrounds to speak up about an extraterrestrial presence. In that same interview, he went on to state that:
A spacecraft went to the rescue of Apollo 13, and they accompanied Apollo 13 on their voyage around the Moon back to Earth. And on two occasions they thought they might have to transfer the crew to their spacecraft, but they saw them safely back to Earth.
This may explain why several astronauts have also been quite outspoken about an extraterrestrial presence, like Edgar Mitchell, Brian O’Leary, Story Musgrave, Gordon Cooper and many others.
Another document from 1965 regarding the CIA keeping tabs on Soviet space plans reads as follows:
Keep in mind, this was more than 50 years ago.
Below is an interesting quote from Carl Sagan:
It is not out of the question that artifacts of these visits still exist, or even that some kind of base is maintained (possibly automatically) within the solar system to provide continuity for successive expeditions. Because of weathering and the possibility of detection and interference by the inhabitants of the Earth, it would be preferable not to erect such a base on the Earth’s surface. The Moon seems one reasonable alternative. Forthcoming high resolution photographic reconnaissance of the Moon from space vehicles – particularly of the back side – might bear these possibilities in mind. (source)
George Leonard’s 1976 book, Somebody Else is on the Moon, and Fred Steckling’s 1981 book, We Discovered Alien Bases on The Moon, also come to mind when discussing this subject.
Members of the Society For Planetary SETI Research (SPSR) recently published a paper in the Journal of Space Exploration about certain features on the far side of the Moon that appear in the crater Paracelsus C. Titled “Image Analysis of Unusual Structures on the Far Side of the Moon in the Crater Paracelsus C,” it argues that these features might be artificial in origin.
The study makes a great point when it comes to the extraterrestrial hypothesis:
A decidedly conservative mainstream scientific establishment often rejects anomalies based on subject matter alone, i.e., there cannot be alien artifacts on the moon because there are no alien artifacts on the moon (or other planets). Such a view is an example of circular reasoning, based on the belief that extraterrestrials do not exist, or if they do exist that they could not have traveled to our solar system.
The truth is, “there is abundant evidence that we are being contacted, that civilizations have been visiting us for a very long time.” – Dr. Brian O’Leary, former NASA astronaut and Princeton Physics Professor (source)
When it comes to the Moon, man-made bases may not be the only ones there.
As far as our own bases are concerned, Karl Wolfe, who was a precision electronics photograph technician at Langley Air Force Base, became well-known when he provided his testimony at National Press Club in Washington, D.C. as part of Dr. Steven Greer’s disclosure project.(source)
Wolfe’s testimony revealed that he was taken into a dark room where images from NASA’s Lunar Orbiter were being developed and stitched together into composite images called “mosaics.”
“They were doing 35 mm strips of film at the time which were then assembled into 18 ½ x 11 mosaics. Those strips were from successive passes around the Moon and they would build up a photograph ,” Wolfe said.(source)
“We walked over to one side of the lab and he said, ‘By the way, we’ve discovered a base on the backside of the moon.’”
Dr. John Brandenburg, the Deputy Manager of the Clementine Mission to the Moon, which was part of a joint space project between the Ballistic Missile Defence Organization (BMDO) and NASA, has also made some fascinating revelations. The mission discovered water at the Moon’s poles in 1994 (Source: page 16 of 18)(source)(source). But, according to Dr. Brandenburg, the Clementine Mission had an ulterior agenda:
“The Clementine Mission was a photo reconnaissance mission basically to check out if someone was building bases on the Moon that we didn’t know about. Were they expanding them?… Of all the pictures I’ve seen from the Moon that show possible structures, the most impressive is a picture of a miles-wide recto-linear structure. This looked unmistakably artificial, and it shouldn’t be there. As somebody in the space defence community, I look on any such structure on the Moon with great concern because it isn’t ours, there’s no way we could have built such a thing. It means someone else is up there.” (Quote from the documentary, “Aliens on the Moon.”)
Neanderthals And Woolly Mammoths May Have Shared Genetic TraitsPauseUnmute/Loaded: 0%Fullscreen3D Heart
A team of Israeli researchers has “printed” the world’s first 3-D vascularized, engineered heart.
On Monday, a team of Tel Aviv University researchers revealed the heart, which was made using a patient’s own cells and biological material. Until now, scientists have successfully printed only simple tissues without blood vessels.Read More Related Articles
This is the first time anyone anywhere has successfully engineered and printed an entire heart replete with cells, blood vessels, ventricles and chambers,” said Prof. Tal Dvir of TAU’s School of Molecular Cell Biology and Biotechnology, Department of Materials Science and Engineering in the Center for Nanoscience and Nanotechnology, and the Sagol Center for Regenerative Biotechnology, who was the lead researcher for the study.
He worked with Prof. Assaf Shapira of TAU’s Faculty of Life Sciences, and Nadav Moor, a doctoral student. Their research was published in Advanced Science.
Heart disease is the leading cause of death among both men and women in the United States. In Israel, it is the second largest cause of death (after cancer). In 2013, heart disease accounted for about 16% of the total number of deaths in Israel, according to the Health Ministry.
Heart transplantation is often the only treatment available to patients with end-stage heart failure. The waiting list for patients in the US can be as much as six months or more. In Israel and the US, many patients die while on the waiting list, hoping for a chance at survival.
“This heart is made from human cells and patient-specific biological materials. In our process, these materials serve as the bio-inks, substances made of sugars and proteins that can be used for 3-D printing of complex tissue models,” Dvir explained.Recommended videosPowered by AnyClipPlayUnmuteCurrent Time 0:02/Duration 0:30Loaded: 22.45% FullscreenUp Next
“People have managed to 3D-print the structure of a heart in the past, but not with cells or with blood vessels. Our results demonstrate the potential of our approach for engineering personalized tissue and organ replacement in the future,” he said.
At this stage, the 3-D heart produced at TAU is sized for a rabbit, but the professors said that larger human hearts could be produced using the same technology.
For the research, a biopsy of fatty tissue was taken from patients, according to a release. The cellular and a-cellular materials of the tissue were then separated. The cells were reprogrammed to become pluripotent stem cells that could then be efficiently differentiated into cardiac or endothelial cells. The extracellular matrix (ECM), a three-dimensional network of extracellular macromolecules, such as collagen and glycoproteins, was processed into a personalized hydrogel that served as the printing “ink.” The differentiated cells were then mixed with the bio-inks and were used to 3D-print patient-specific, immune-compatible cardiac patches with blood vessels and, subsequently, an entire heart.
According to Dvir, the use of “native” patient-specific materials is crucial to successfully engineering tissues and organs.
The next step, they said, is to teach the hearts to behave like human hearts. First, they will transplant them into animals and eventually into humans. The hope is that within “10 years, there will be organ printers in the finest hospitals around the world, and these procedures will be conducted routinely,” Dvir said.

Lockheed Martin unveiled a design for a human-rated lunar lander that could be built quickly to meet Vice President Mike Pence’s challenge to return humans to the Moon by 2024.
The two-stage lander concept was presented April 10, 2019, during the 35th Space Symposium in Colorado Springs, Colorado, where engineers from Lockheed Martin discussed ideas on how to accelerate lunar lander capabilities.
NASA’s current plan to return humans to the Moon is expected in two phases, as outlined by the agency’s administrator, Jim Bridenstine, earlier this week. The first phase is about speed and involves building an initial Lunar Gateway (described as a reusable command module in orbit around the Moon) likely with just a power and propulsion module and a utilization module with docking ports.
Ultimately, the Gateway is being designed to allow for Orion crews to dock and transfer to a reusable lunar lander architecture. It would also be in an orbit that requires little fuel to maintain while allowing for access to a large portion of the Moon’s surface. In the future, the vehicle is envisioned as being a rendezvous location for commercial resupply and refueling ships to replenish a reusable Moon exploration architecture.
NASA envisions a three-part lunar lander system, built via public-private partnerships consisting of a transfer vehicle to travel to low-lunar orbit, a descent vehicle to land on the Moon and an ascent vehicle to return back to the Gateway.

However, Lockheed Martin’s lander concept only requires two of those: the descent and ascent vehicles. Moreover, they are expected to be, in part, based off NASA’s Orion crew module, of which Lockheed Martin is the prime contractor.
Orion is currently slated to launch atop NASA’s long-delayed Space Launch System as early as 2020. Known as Exploration Mission-1, it is expected to fly around the Moon before returning to Earth to test much of the spacecrafts systems.
EM-2 is expected to follow as soon as 2022 and will be a full-up human flight, likely utilizing a free-return trajectory around the Moon.
However, Lockheed Martin is proposing that it accelerate development on Orion’s docking hardware and software, including elements of design of the European service module, to allow for EM-2 to dock with the first modules of the Gateway, likely just the power and propulsion module and a utilization module with docking ports.
Those flights would test much of the hardware and software that would go into the proposed lunar lander, which the company would be developing in parallel, another key principle laid out by Bridenstine to allow for a speedy return to the Moon.
EM-3, would then be freed to send a crew in 2024 to the Gateway where its lunar lander could be waiting for them to take at least part of the crew to the surface.

Lockheed Martin said that for this plan to work on an aggressive five-year schedule, engineers would need to start “bending metal” next year. By late 2020, the focus would be on the avionics and software as a basis for systems testing and the beginning of crew training. Additionally, the company said resources from NASA—money—will be required for this to be built.
According to Lockheed Martin, a robotic tech demo would be planned for between 2021 and 2022 in order to further reduce risk.
Lockheed Martin has also been testing Gateway habitat prototypes at Kennedy Space Center since 2015 as part of NASA’s Next Space Technologies for Exploration Partnerships (NextSTEP) program.
The company’s designs are based based on the Multi-purpose Logistics Modules, which were originally designed to provide logistics for the ISS. The prototype can be reconfigured for numerous missions.
Several companies are contracted under this program, including Boeing, Northrop Grumman, Bigelow Aerospace, etc, but Lockheed Martin was the first to turn the prototype to NASA for testing. Engineers are studying how Orion and future habitats could dock with Gateway.
Numerous systems are in the process of being designed and studied—including life support, radiation protection, thermal control, power, rendezvous, proximity, operations and docking, an airlock and communications—in order to determine which would work best in deep space.

CAPE CANAVERAL, Fla. — SpaceX’s Falcon Heavy successfully launched its first operational mission today (April 11), sticking a triple-rocket landing more than a year after its demo mission catapulted a cherry-red Tesla and a dummy nicknamed Starman into space.
The megarocket, dubbed the most powerful launcher in operation, blasted off at 6:35 p.m. EDT (2235 GMT). It lifted off here from the same site that once hosted NASA’s Apollo moon missions and its fleet of space shuttles: historic Pad 39A at NASA’s Kennedy Space Center. About 34 minutes later, the rocket deployed Arabsat-6A, an advanced communications satellite that will provide internet and communications services to residents of the Middle East, Africa and parts of Europe.
Falcon Heavy’s second flight went off without a hitch at the beginning of a 2-hour window after high upper level winds thwarted SpaceX’s second launch attempt. A day earlier, Falcon Heavy faced a 24-hour delay due to poor weatherat the launch pad. A dismal weather forecast for Tuesday (April 9) convinced launch officials to issue a delay rather than face just a 30% chance of favorable weather.
Today’s flight was the first of a Falcon Heavy launch featuring souped-up Block 5versions of its component rockets. (A Falcon Heavy rocket is built of three Falcon 9 first stages, which are combined to form the 27-engine megarocket.) As the rocket’s first-stage engines roared to life, they fired in unison and spewed smoke and fire around the launch pad.
SpaceX made the transition to Block 5 for its Falcon 9 flights in May, after the demo flight of Falcon Heavy in February 2018. Today’s Falcon Heavy boasted more than 5 million lbs. of thrust, a 10% increase over its predecessor.
In addition to the added thrust, the Block 5 Falcon 9 now features a plethora of upgrades, all of which are designed to facilitate reusability. Previous versions of the Falcon 9 were meant to fly only two to three times; however, Musk says the Block 5 is capable of flying as many as 10 times with virtually no refurbishment between flights.Touchdowns! SpaceX Lands All 3 Falcon Heavy Boosters After Launching SatelliteVolume 0%
To achieve that goal, engineers developed a suite of upgrades for the company’s flagship rocket. The design changes — including improved engines, a more durable interstage (the piece that connects the rocket’s two stages), titanium grid fins and a new thermal protection system — were developed to help the rocket better handle the stresses of launch. These technological advances have enabled the company to establish a growing fleet of flight-proven rockets.
Falcon Heavy now has two spaceflights under its belt. Its first mission launched on Feb. 6, 2018, ferrying Elon Musk’s cherry-red Tesla Roadster — with a spacesuit-wearing test dummy named Starman sitting in the driver’s seat — into orbit. The nearly flawless first launch, which included successful landings by two of the Falcon Heavy’s three first-stage boosters, earned SpaceX major accolades.
The enthusiasm carried over into today’s flight, as thousands of onlookers gathered in the area to watch the Falcon Heavy fly.
Sonic booms echoed through the sky as the rocket’s two side boosters touched down in unison at SpaceX’s nearby landing sites. The third landed on SpaceX’s drone ship landing pad “Of Course I Still Love You,” stationed in the Atlantic Ocean. (That represents an improvement over the rocket’s first flight, when the core stage missed the drone ship and splashed down in the Atlantic Ocean after two of three engines did not fire during the descent.)Watch 3 Boosters Put Together to Form Falcon HeavyVolume 0%
With its first operational Heavy flight in the books, SpaceX is ready to forge ahead with a steady schedule of launches. The next Falcon Heavy flight, due to launch this year, will carry the Space Test Program 2 mission for the U.S. Air Force and a solar-sail mission for The Planetary Society.
The Falcon Heavy is part of a growing list of SpaceX launch services and ongoing projects, which could include launching astronauts to the space station later this year during Crew Dragon‘s first crewed test flight. But Falcon Heavy won’t be the most powerful rocket in SpaceX’s arsenal for long. SpaceX is in the early stages of developing a launch system even larger than the Falcon Heavy.
Just days before today’s launch, on April 5, the company hit the end of its tether on Starhopper, a test prototype for that massive rocket. That’s an initial stage of the company’s Starship program to design a fully reusable deep-space launcher for missions to the moon, Mars and beyond. The program already has its first passenger: SpaceX announced last September that Japanese entrepreneur Yusaku Maezawa has booked a trip around the moon that’s slated to fly no earlier than 2023.
SpaceX’s next launch from the Cape is currently scheduled for April 26, when a Falcon 9 rocket will ferry a Dragon cargo capsule to the International Space Station.
Scientists have obtained the first image of a black hole, using Event Horizon Telescope observations of the center of the galaxy M87.
Scientists have released the first-ever image of a black hole, revealing the distant object in stunning detail.
The groundbreaking discovery was made by the Event Horizon Telescope, an international project involving telescopes across the globe that describes itself as a “virtual Earth-sized telescope.” Telescopes in Hawaii, Arizona, Chile, Mexico, Spain and the South Pole participated in the ambitious research project.
The black hole was spotted in galaxy Messier 87 (M87) that is 55 million light years away. A light year, which measures distance in space, equals 6 trillion miles.
“We’re delighted to report to you today that we have seen what we thought was unseeable,” explained Dr. Shep Doeleman, director of the Event Horizon Telescope, during a press conference at the National Science Foundation Wednesday. “We have taken advantage of a cosmic opportunity.”View image on Twitter
“This was a Herculean task,” explained National Science Foundation Director Dr. France Cordova, during the press conference, noting that the Event Horizon Telescope’s findings transform and enhance our understanding of black holes. The National Science Foundation has invested $28 million in Event Horizon Telescope project.
The black hole has a mass 6.5 billion times that of the Sun, according to the researchers, who captured the image of a ring-like structure with a dark central region, which is the black hole’s “shadow.”
“”If immersed in a bright region, like a disc of glowing gas, we expect a black hole to create a dark region similar to a shadow — something predicted by Einstein’s general relativity that we’ve never seen before,” explained Heino Falcke of Holland’s Radboud University and chair of the EHT Science Council, in a statement. “This shadow, caused by the gravitational bending and capture of light by the event horizon, reveals a lot about the nature of these fascinating objects and allowed us to measure the enormous mass of M87’s black hole.”
The shadow of a black hole is the closest we can come to an image of the black hole itself, according to the EHT scientists. “The black hole’s boundary — the event horizon from which the EHT takes its name — is around 2.5 times smaller than the shadow it casts and measures just under 40 billion km [24.8 billion miles] across.,” the explain, in the statement.
“Black holes are extremely dense pockets of matter, objects of such incredible mass and miniscule volume that they drastically warp the fabric of space-time,” explains the National Science Foundation, on its website. “Anything that passes too close, from a wandering star to a photon of light, gets captured. Most black holes are the condensed remnants of a massive star, the collapsed core that remains following an explosive supernova.”
The SpaceX rocket expected to vault a Saudi communications satellite into orbit on April 10 is also auditioning to explore space with NASA.
The Falcon Heavy rocket is the most powerful operational rocket in the world, designed to fly the largest satellites into the highest orbits over the earth. The communications satellite being flown in this launch, Arabsat-6A, weighs about six metric tons (6.6 tons).
The vehicle is effectively three of SpaceX’s reusable Falcon 9 boosters lashed together. It debuted with a Feb. 2018 flight that sent a Tesla roadster into orbit around the sun.
SpaceX warned residents of the Florida coast that there are likely to be three large sonic booms when the three boosters return to earth after delivering the satellite.
Arabsat-6A will be launched to an orbit roughly 36,000 km (22,369 miles) above the earth, where it will remain over Africa, the Middle East and Europe as it circles the earth.
You can watch the launch and attempt to return the boosters at 6:36 pm EDT on SpaceX’s live stream:
SpaceX is still showing NASA that its rockets are safe enough to fly astronauts to the International Space Station. A successful test run of that mission in March showed that the company’s Dragon spacecraft was capable of successfully flying to the ISS, docking with the orbital habitat, and then returning to earth to splashdown in the ocean. That means the company could actually launch a crewed flight later this year, pending a few other loose ends.
One requirement is that the company fly seven times using an approved system of pressurized gas canisters in its rockets. Those canisters, known as composite overwrap pressure vessels or COPVs, were linked to a 2016 fire that destroyed a SpaceX rocket and satellite.
SpaceX and NASA re-configured the system and have now flown it six times in the upper stage of the Falcon 9 rocket and twice in the reusable booster stage. This Falcon Heavy flight will feature the new COPVS in both stages of center booster, which could give NASA the data it needs to finally certify the design for human spaceflight.
The Falcon Heavy earned global plaudits when it launched, but got a distinctly cool reception from the US space establishment, which has spent $17 billion on a Boeing-built heavy rocket called the Space Launch System (SLS) that faces lengthy delays.
However, in March, NASA administrator James Bridenstine raised the possibility of keeping a planned lunar test of an uncrewed deep-space vehicle on schedule for 2020 by launching it on a commercially-available rocket like the Falcon Heavy instead of waiting for SLS.
SpaceX’s rocket only has about 60% of the lifting power of the SLS, but it costs about one-tenth per launch thanks in part to its reusable boosters, and it is flying today. Using it for the moon mission would come with its own technical hurdles, like figuring out how to mate the spacecraft, called Orion, with the Falcon Heavy, and then to re-fuel it in orbit.
It might be feasible, but only if the Falcon Heavy continues to demonstrate its capabilities with this launch and four others scheduled in the coming years.

In the 1960s animated sitcom The Jetsons, George Jetson commutes to work in his family-size flying car, which miraculously transforms into a briefcase at the end of the trip.
A new study of the environmental sustainability impacts of flying cars, formally known as electric vertical takeoff and landing aircraft, or VTOLs, finds that they wouldn’t be suitable for a Jetsons-style short commute.
However, VTOLs — which combine the convenience of vertical takeoff and landing like a helicopter with the efficient aerodynamic flight of an airplane — could play a niche role in sustainable mobility for longer trips, according to the study, scheduled for publication April 9 in Nature Communications. Several companies around the world are developing VTOL prototypes.
Flying cars would be especially valuable in congested cities, or in places where there are geographical constraints, as part of a ride-share taxi service, according to study authors from the University of Michigan’s Center for Sustainable Systems and from Ford Motor Co.
“To me, it was very surprising to see that VTOLs were competitive with regard to energy use and greenhouse gas emissions in certain scenarios,” said Gregory Keoleian, senior author of the study and director of the Center for Sustainable Systems at U-M’s School for Environment and Sustainability.
“VTOLs with full occupancy could outperform ground-based cars for trips from San Francisco to San Jose or from Detroit to Cleveland, for example,” he said.
The U-M-Ford study, the first comprehensive sustainability assessment of VTOLs, looked at the energy use, greenhouse gas emissions and time savings of VTOLs compared to ground-based passenger cars. Although VTOLs produce zero emissions during flight, their batteries require electricity generated at power plants.
The researchers found that for trips of 100 kilometers (62 miles), a fully loaded VTOL carrying a pilot and three passengers had lower greenhouse gas emissions than ground-based cars with an average vehicle occupancy of 1.54. Emissions tied to the VTOL were 52 percent lower than gasoline vehicles and 6 percent lower than battery-electric vehicles.
Akshat Kasliwal, first author of the study and a graduate student at the U-M School for Environment and Sustainability, said the findings can help guide the sustainable deployment of an emerging mobility system prior to its commercialization.
“With these VTOLs, there is an opportunity to mutually align the sustainability and business cases,” Kasliwal said. “Not only is high passenger occupancy better for emissions, it also favors the economics of flying cars. Further, consumers could be incentivized to share trips, given the significant time savings from flying versus driving.”
In the coming decades, the global transportation sector faces the challenge of meeting the growing demand for convenient passenger mobility while reducing congestion, improving safety and mitigating climate change.
Electric vehicles and automated driving may contribute to some of those goals but are limited by congestion on existing roadways. VTOLs could potentially overcome some of those limitations by enabling piloted taxi services or other urban and regional aerial travel services.
Several aerospace corporations and startup companies — Airbus, Boeing, Joby Aviation and Lilium, for example — and agencies such as NASA have developed VTOL prototypes. One critical efficiency enabler for these aircraft is distributed electric propulsion, or DEP, which involves the use of several small, electrically driven propulsors.
The U-M and Ford researchers used publicly available information from these sources and others to create a physics-based model that computes energy use and greenhouse gas emissions for electric VTOLs.
“Our model represents general trends in the VTOL space and uses parameters from multiple studies and aircraft designs to specify weight, lift-to-drag ratio and battery-specific energy,” said Noah Furbush, study co-author and a master’s student at the U-M College of Engineering.
“In addition, we conducted sensitivity analyses to explore the bounds of these parameters, alongside other factors such as grid carbon intensity and wind speed,” said Furbush, who is also a member of the U-M football team.
The study began while Kasliwal and Furbush were summer interns at Ford. The work continued when the students returned to Ann Arbor, with the help of a Ford-University of Michigan Alliance grant.
The researchers analyzed primary energy use and greenhouse gas emissions during the five phases of VTOL flight: takeoff hover, climb, cruise, descent and landing hover. These aircraft use a lot of energy during takeoff and climb but are relatively efficient during cruise phase, traveling at 150 mph. As a result, VTOLs are most energy efficient on long trips, when the cruise phase dominates the total flight miles.
But for shorter trips — anything less than 35 kilometers (22 miles) — single-occupant internal-combustion-engine vehicles used less energy and produced fewer greenhouse gas emissions than single-occupant VTOLs. That’s an important consideration because the average ground-based vehicle commute is only about 17 kilometers (11 miles).
“As a result, the trips where VTOLs are more sustainable than gasoline cars only make up a small fraction of total annual vehicle-miles traveled on the ground,” said study co-author Jim Gawron, a graduate student at the U-M School for Environment and Sustainability and the Ross School of Business. “Consequently, VTOLs will be limited in their contribution and role in a sustainable mobility system.”
Not surprisingly, the VTOL completed the base-case trip of 100 kilometers much faster than ground-based vehicles. A point-to-point VTOL flight path, coupled with higher speeds, resulted in time savings of about 80 percent relative to ground-based vehicles.
“Electrification of aircraft, in general, is expected to fundamentally change the aerospace industry in the near future,” Furbush said.
The study’s authors note that many other questions need to be addressed to assess the viability of VTOLs, including cost, noise and societal and consumer acceptance.
London, England. Credit: GoogleA British witness at London reported watching a black, triangle-shaped object “about two-to-three times the size of an A380 passenger jet moving overhead, according to testimony in Case 92298 from the Mutual UFO Network (MUFON) witness reporting database.
The witness and his wife were standing in their backyard having a cigarette at 11:30 p.m. on May 1, 2018.
“Jupiter was very low in the sky and we were wondering what it was?” the witness stated. “We got out my phone and used the Skyview app to work it out. We both commented on the fact that we hadn’t ever remembered seeing Jupiter or if we had, we didn’t know that’s what it was. London skies are always full of passenger aircraft coming into land at Heathrow and we are on one of the flight paths they use. The planes come in from the east over our house and then head out west before they turn north towards Heathrow airport. You can always hear them. This black triangle object with round lights on each of its three corners and one central light that was reddish orange in color appeared in the west.”
The witness said the object was about two-to-three times the size of an A380 passenger jet.
“It flew right over us in one fluid motion, in a slight arch. It rotated slowly as it moved across the sky. It probably made one full rotation in the time we witnessed it. It flew from the west horizon to the northeast horizon in about 8-10 seconds. It was completely silent. The sky was completely clear. There were no clouds and the stars were very visible. We both watched this object come in and pass right over us both. We both knew exactly what we had both seen. It was like watching a silent fiction movie or one of those UFO TV shows, but real life. We both just watched it until it wasn’t visible anymore, then looked at each other both with shocked but excited faces and said, ‘what was that.’ Then we both said together, ‘that was a UFO for sure,’ We both knew exactly what we had seen. We are in the photography/film industry. We use our eyes for our job. This object was so clearly a solid structure, but it also had a film static kind of shimmer to the underside of it, a bit like digital glitch. I know it sounds ridiculous, but it was like its cloaking device was switching on or switching off. This was so incredibly strange and overwhelming it has most defiantly changed our view on UFOs.”
United Kingdom MUFON Field Investigator Karl Webb closed this case as an Unknown Aerial Vehicle.
A hypersonic ‘spaceplane’ just passed a crucial test for its precooler component. If and when the jet becomes available for commercial use, it could fly people from London to New York in less than 60 minutes.
A ‘spaceplane’ that flies 25 times faster than the speed of sound has successfully passed a crucial testing milestone.
The hypersonic plane is so fast it could jet from London to New York in less than 60 minutes and transport you from the UK to Australia in four hours.
Oxford-based Reaction Engines has been working with the European Space Agency and the UK Space Agency, along with BAE Systems, to make the powerful aircraft.
Reaction Engines has recently been testing a ‘pre-cooler’ for the plane, which is technology that would allow it to travel faster than ever before.
The pre-cooler is critical in the plane’s development because it is required to stop the engine from melting by lowering the temperature of compressed air in the engine from more than 1,000°C to room temperature in one-twentieth of a second.
Thousands of tubes inside the pre-cooler, which are thinner than human hair, contain liquid helium that can cool the air as it rushes past them.
Until now, heat has been a limiting factor for how fast aircraft can travel, including Concorde which traveled at two times the speed of sound.
This technology could now be combined with the spaceplane’s experimental engine, referred to as Sabre.
Sabre is intended to be much lighter than a conventional rocket engine because it would carry less fuel-oxidant.
It is being designed to draw oxygen into the engine to use for combustion from take off until it reaches just over 4,000 mph.
After this point, the engine would need to burn liquid oxygen and liquid hydrogen from on-board fuel tanks.
The spaceplane would need to continue using this process until it reached 25 times the speed of sound to enter space.
The company ultimately aims to create a reusable vehicle that has the fuel efficiency of a jet engine with the power of a rocket.
Plans for the hypersonic plane don’t just include getting people around the world in a fraction of the time but also taking people or cargo into Space and back for just a fraction of the current cost.
“I am in full acceptance of my guilt, and with deep regret and shame over what I have done, I accept full responsibility for my actions and will accept the consequences that stem from those actions,” Huffman continued. “I am ashamed of the pain I have caused my daughter, my family, my friends, my colleagues and the educational community. I want to apologize to them and, especially, I want to apologize to the students who work hard every day to get into college, and to their parents who make tremendous sacrifices to support their children and do so honestly.

“My daughter knew absolutely nothing about my actions, and in my misguided and profoundly wrong way, I have betrayed her. This transgression toward her and the public I will carry for the rest of my life. My desire to help my daughter is no excuse to break the law or engage in dishonesty,” she concluded.
“I am in full acceptance of my guilt, and with deep regret and shame over what I have done.”— Actress Felicity Huffman
The Department of Justice revealed on Monday that Huffman was one of the 11 defendants, who was charged with one count of conspiracy to commit mail fraud and honest services mail fraud, and have agreed to plead guilty pursuant to plea agreements.
In addition, two other defendants, who are facing other charges, both agreed to plead guilty to one count of conspiracy to commit mail fraud and honest services mail fraud, federal prosecutors said. The former head coach for the men’s tennis team at the University of Texas at Austin was also charged and has agreed to plead guilty to one count of conspiracy to commit mail fraud and honest services mail fraud.
Last week, Huffman appeared in a Boston federal court. She is accused of paying $15,000 disguised as a tax-deductible charitable donation so her daughter could take part in an apparently rigged college entrance exam.
Court documents stated that a cooperating witness met with the actress and her husband, “Shameless” star William H. Macy, at their Los Angeles home and explained to them that he “controlled” a testing center and could have someone secretly alter her daughter’s answers. The person told investigators the couple agreed to the plan.
Huffman was arrested and released on a $250,000 bond last month. Macy was not charged.
More than four dozen people have been charged in the nationwide scam, which is alleged to have placed students in top-tier schools like Yale, Georgetown, Stanford, the University of Southern California, UCLA and the University of Texas. A federal investigation into the matter – dubbed “Operation Varsity Blues” – has been ongoing for more than a year.
Fellow actress Lori Loughlin and Loughlin’s fashion designer husband, Mossimo Giannulli, are also charged in the scam. They are not among those who’ve agreed to plead guilty and haven’t publicly addressed the allegations.
