    BRITISH WITNESS SAYS UFOS APPEARED OVERHEAD
    Roger Marsh, MUFON | February 26, 2019

    Two United Kingdom witnesses at Wrexham reported watching three unusual craft from a distance that quickly moved to the tree top level and less than 20 feet away, according to testimony in Case 93128 from the Mutual UFO Network (MUFON) witness reporting database.

    The events began at 1:30 a.m. on July 3, 2018.

    “Observed a star-like object in sky over a farmer’s field approaching from right,” the reporting witness stated. “Believed it to be the ISS until it suddenly curved direction and started to descend. Another object of identical appearance then appeared on far left of sky and accelerated to the first object. They avoided each other and continued hovering and moving in severe, yet smooth movements.”

    The witness observed these for two to three minutes.“An orb of light then materialized approximately 12 feet above us and fired diagonally towards the objects. Orb appeared like a mini explosion of light and approximately the size of a baseball.

    Orb consisted of a solid white light yet dim in center and a beige sandy X-shaped object in its core. No sound. Two witnesses - one experiencing severe terror and evacuated field immediately. Objects no longer visible after exiting field.

    MUFON United Kingdom Field Investigator Karl Webb investigated and closed this case as an Unknown Aerial Vehicle.

    Hubble solves puzzle of Neptune mystery moon
    Paul Scott Anderson in SPACE | March 2, 2019

    Meet Hippocamp, the smallest known moon of the planet Neptune. Scientists have puzzled over its origin, and over why we see it orbiting where we do. Now, new Hubble data has shed light on these mysteries.


    Diagram of the inner moons of Neptune, including Hippocamp. Image via Nature.

    The origin of Neptune’s smallest known moon – Hippocamp – has been a mystery since this moon was first discovered in 2013. It orbits close to a larger Neptune moon, whose presence should have knocked Hippocamp out of orbit. That’s why astronomers have referred to it as “the moon that shouldn’t be there.” Now a new study – published February 20, 2019, in the peer-reviewed journal Nature – describes a possible solution to the mystery.

    The study discusses scientists’ most recent ideas about where the moon came from, and why we still see it where we see it. Data for the study came from both the Hubble Space Telescope and the Voyager 2 spacecraft, which sped past Neptune in 1989.

    Hippocamp is very tiny, only about 20 miles (34 km) in diameter. Its orbit is very close to that of Proteus, Neptune’s second-largest moon and the outermost of the planet’s inner moons. Proteus is 260 miles (418 kilometers) in diameter.

    The orbits of Hippocamp and Proteus are only 7,456 miles (12,000 km) apart, which didn’t make sense, since normally it would be expected that the much larger moon would knock the much smaller one out of orbit, or the smaller one would collide with the larger one. But, apparently, that didn’t happen with Hippocamp. As noted by Showalter:

    The first thing we realized was that you wouldn’t expect to find such a tiny moon right next to Neptune’s biggest inner moon. In the distant past, given the slow migration outward of the larger moon, Proteus was once where Hippocamp is now.

    So what is the explanation? The research team concluded that rather than being two moons that formed separately, Hippocamp is instead a “chip” knocked off of Proteus by an asteroid or comet billions of years ago. When Voyager 2 looked at Proteus with its cameras in 1989, it saw a large impact crater, which earthly astronomers call Pharos. If this scenario is correct, the rocky object that hit Proteus almost destroyed it, but instead, a smaller piece was broken off that became Hippocamp. According to Showalter:

    In 1989, we thought the crater was the end of the story. With Hubble, now we know that a little piece of Proteus got left behind and we see it today as Hippocamp.

    The entire moon system of Neptune has had a violent history – Proteus is thought to have formed from the debris left over after Neptune’s largest moon Triton was captured from the Kuiper Belt billions of years ago. If that happened, it also shattered Neptune’s other smaller moons at the time.

    The other Neptune moons we see today are thought to be “second-generation” moons, which all formed from the debris of that early catastrophe. But since Hippocamp formed even later than those moons, it’s now considered to be a “third-generation” moon. As explained by Jack Lissauer of NASA’s Ames Research Center, a co-author of the new research:

    Based on estimates of comet populations, we know that other moons in the outer solar system have been hit by comets, smashed apart, and re-accreted multiple times. This pair of satellites provides a dramatic illustration that moons are sometimes broken apart by comets.

    The name Hippocamp originates from a half-horse, half-fish creature from Greek mythology; all the moons of Neptune are named after Greek and Roman mythological figures of the undersea world.

    Thanks to the Hubble Space Telescope and Voyager 2, the mystery of the moon Hippocamp’s origin seems to have been solved. The data also provide more insight into how chaotic the history of Neptune’s moon system has been over the course of billions of years. While some moons may be obliterated – or nearly so – others can be created.

    Bottom line: The origin of Neptune’s smallest known moon – Hippocamp – has long been a mystery, but now thanks to the Hubble Space Telescope, astronomers think it was a piece broken off a larger, nearby moon called Proteus by an asteroid or comet impact.

    Planet 9 hypothesis gets a boost
    Paul Scott Anderson in SPACE | March 3, 2019

    A large, unknown Planet 9 in our solar system continues to elude astronomers. But a new review article in Physics Reports explains why some scientists still think they’ll find it.


    Diagrams showing the calculated orbit of Planet 9 in the outer solar system – much farther out than Neptune – and estimated size compared to the other planets. Image via James Tuttle Keane/Caltech.
    Does a large Planet 9 – a hypothesized planet several times the mass of Earth in the distant outer reaches of the solar system – really exist? That question is still a topic of heated debate among astronomers. Some think a large Planet 9 can explain the weird orbits of some of the smaller known bodies in the Kuiper Belt. Others think that those orbits might be caused by multiple unknown smaller bodies instead.

    Several astronomers recently reviewed the evidence for Planet 9 in an article published in February 2019 by Physics Reports. This peer-reviewed journal aims to publish long and deep reviews – more extensive than just literature surveys – on timely topics in physics. The article is called The planet nine hypothesis, and the astronomers who wrote it are still very optimistic that Planet 9 will eventually be found and confirmed. According to co-author Fred Adams at the University of Michigan:

    The strongest argument in favor of Planet 9 is that independent lines of evidence can all be explained by a proposed new planet with the same properties. In other words, there are multiple reasons to believe that Planet 9 is real, not just one.

    From the review article in Physics Reports:

    Over the course of the past two decades, observational surveys have unveiled the intricate orbital structure of the Kuiper Belt, a field of icy bodies orbiting the sun beyond Neptune. In addition to a host of readily-predictable orbital behavior, the emerging census of trans-Neptunian objects displays dynamical phenomena that cannot be accounted for by interactions with the known eight-planet solar system alone.

    Planet 9 – so-called since Pluto is no longer officially considered a major planet – was first hypothesized by astronomers Konstantin Batygin and Mike Brown of Caltech three years ago. Its existence could explain the odd orbits of some objects in the Kuiper Belt known as trans-Neptunian objects (TNOs). The orbits of these small bodies are clustered together in a way that suggests to some astronomers that a larger and more distant world (a Planet 9) has been tugging on them with its relatively strong gravity.

    Mike Brown explained that the new review paper does not prove Planet 9’s existence. But, he said:

    … it does indicate that the hypothesis rests upon a solid foundation.

    In a previous paper published on January 22, 2019, in The Astronomical Journal, astronomers calculated that the likelihood of Planet 9 not existing was only 1 in 500.

    If real, Planet 9 is estimated to be about five to 10 times the mass of Earth, possibly making it similar to super-Earth-type exoplanets – larger than Earth but smaller than Neptune. If it exists, Planet 9 may be on an elongated orbit, taking it up to 400 times the distance of Earth from the sun; that is very far away! The orbit is also calculated to be 15 to 20 degrees off the main orbital plane in which most of the other planets orbit.

    Planet 9 has not been easy to find – assuming it’s actually there – so how long might it be before it is finally found? Adams thinks that, within the next 10 to 15 years, astronomers will either confirm that Planet 9 exists or refute it via the data. He said:

    With its proposed properties, Planet 9 is right on the edge of being observable. But this is a very dim object in a very big sky. Since we don’t know exactly where it is, you have to survey the whole sky, or at least large portions of it, in order to find the planet.

    Over the course of the next 10 years, we will have deeper and deeper – which means more sensitive – sky surveys. So I think by 2030 we will have seen it or will have a better idea of where it is. Of course, it’s also possible that by then we could also have alternate explanations for the observed orbital anomalies.

    Juliette Becker is a doctoral candidate from University of Michigan’s Department of Astronomy and a co-author on the new review paper about Planet 9. She thinks that discovering Planet 9 would help answer various mysteries in the solar system, including the origin of the rocky object labeled 2015 BP519 and nicknamed Caju. This object is one of the TNOs thought to be gravitationally affected by Planet 9. It is only 340 miles (550 kms) in diameter and is on a highly eccentric and inclined orbit. She said:

    Planet 9 is a really good explanation for 2015 BP519. The physics works perfectly. However, until we see Planet 9 in an image and are sure it’s there, I don’t feel like we’ve truly solved the mystery of its origin. The presence of Planet 9 would beautifully and coherently answer several seemingly unrelated open questions about the solar system. I look forward to the day we either see it or rule it out so that we can conclusively answer these questions.

    By the way, there is even a theory that Planet 9 might be an exoplanet – such as a super-Earth – that was “stolen” by the sun from a nearby star. So you see that astronomers truly are perplexed about the orbits of these outer solar system bodies. They are casting around for ideas to explain them.

    If a Planet 9 is found, whatever its origin, it will be one of the most exciting space discoveries in history. Since Pluto lost its major planet status in 2006, Neptune has been considered the most distant large planet from the sun in our solar system. If that’s not the case, if another large planet – a Planet 9 – exists, it’ll provide astronomers with an unprecedented opportunity to learn more about how our solar system originated and evolved.

    Bottom line: Finding Planet 9 – if it really exists – is still a difficult task for astronomers, but the new study in Physics Reports reflects astronomers’ continued optimism that it will be found in the relatively near future.

    Asteroids are harder to destroy than we thought
    Deborah Byrd in SPACE | March 4, 2019

    What if we learned an asteroid was headed toward Earth? How much energy does it take to destroy an asteroid and break it into pieces? More than we thought, it turns out.


    In recent decades, astronomers have become increasingly aware that asteroids and comets do sometimes strike Earth. Funding has increased for studies in which our skies are scanned for asteroids, which is the main reason we hear so often nowadays about asteroids sweeping relatively near the Earth. What’s more, astronomers have met to discuss what might happen if we found an asteroid headed our way. Popular books and movies have taken up this theme, too, with the idea we might send spacecraft to the asteroid to blow it up. But – according to a new study from Johns Hopkins University – blowing up an asteroid might not be easy.

    These scientists used a new understanding of how rocks fracture, and a new computer modeling method, to simulate asteroid collisions. Charles El Mir, a recent Ph.D. graduate from Johns Hopkins University’s Department of Mechanical Engineering and the paper’s first author, commented in a statement:

    We used to believe that the larger the object, the more easily it would break, because bigger objects are more likely to have flaws. Our findings, however, show that asteroids are stronger than we used to think and require more energy to be completely shattered.

    These scientists’ findings will be published in the March 15, 2019, print issue of the peer-reviewed journal Icarus (preprint here).

    They said their work can:

    … aid in the creation of asteroid impact and deflection strategies, increase understanding of solar system formation and help design asteroid mining efforts.

    The statement from Johns Hopkins explained:

    Researchers understand physical materials like rocks at a laboratory scale (about the size of your fist), but it has been difficult to translate this understanding to city-size objects like asteroids. In the early 2000s, a different research team created a computer model into which they input various factors such as mass, temperature, and material brittleness, and simulated an asteroid about a kilometer (.6 mile) in diameter striking head-on into a 15-mile (25-km) diameter target asteroid at an impact velocity of 3 miles (5 km) per second. Their results suggested that the target asteroid would be completely destroyed by the impact.

    In the new study, El Mir and his colleagues, K. T. Ramesh, director of the Hopkins Extreme Materials Institute and Derek Richardson, professor of astronomy at the University of Maryland, entered the same scenario into a new computer model called the Tonge-Ramesh model, which accounts for the more detailed, smaller-scale processes that occur during an asteroid collision. Previous models did not properly account for the limited speed of cracks in the asteroids.

    The simulation was separated into two phases: a short-timescale fragmentation phase and a long-timescale gravitational reaccumulation phase. The first phase considered the processes that begin immediately after an asteroid is hit, processes that occur within fractions of a second.

    The second, long-timescale phase considers the effect of gravity on the pieces that fly off the asteroid’s surface after the impact, with gravitational reaccumulation occurring over many hours after impact.

    In the first phase, after the asteroid was hit, millions of cracks formed and rippled throughout the asteroid, parts of the asteroid flowed like sand, and a crater was created. This phase of the model examined the individual cracks and predicted overall patterns of how those cracks propagate.

    The new model showed that the entire asteroid is not broken by the impact, unlike what was previously thought. Instead, the impacted asteroid had a large damaged core that then exerted a strong gravitational pull on the fragments in the second phase of the simulation.

    The research team found that the end result of the impact was not just a ‘rubble pile’ – a collection of weak fragments loosely held together by gravity. Instead, the impacted asteroid retained significant strength because it had not cracked completely, indicating that more energy would be needed to destroy asteroids. Meanwhile, the damaged fragments were now redistributed over the large core, providing guidance to those who might want to mine asteroids during future space ventures.

    El Mir commented:

    Our question was, how much energy does it take to actually destroy an asteroid and break it into pieces?

    It may sound like science fiction but a great deal of research considers asteroid collisions. For example, if there’s an asteroid coming at Earth, are we better off breaking it into small pieces, or nudging it to go a different direction? And if the latter, how much force should we hit it with to move it away without causing it to break? These are actual questions under consideration.

    Ramesh added:

    We are impacted fairly often by small asteroids, such as in the Chelyabinsk event a few years ago. It is only a matter of time before these questions go from being academic to defining our response to a major threat. We need to have a good idea of what we should do when that time comes – and scientific efforts like this one are critical to help us make those decisions.

    Bottom line: Researchers at Johns Hopkins employed a new understanding of how rocks fracture, and a new computer modeling method, to simulate asteroid collisions. They found that asteroids are harder to shatter than previously believed.

    How the moon got its sunburn
    SPACE | March 7, 2019

    Every object, planet or person traveling through space has to contend with the sun’s damaging radiation – and the moon has the scars to prove it.


    Research using data from NASA’s ARTEMIS mission suggests that some of the coloration we see on the moon could be a form of sunburn.

    Here on Earth, we’re largely protected from the damaging effects of the solar wind – the stream of charged particles released from the sun’s upper atmosphere. That’s because the solar wind is magnetized, and Earth’s natural magnetic field deflects the solar wind particles around our planet so that only a small fraction of them reach our planet’s atmosphere.

    But the moon has no global magnetic field. Magnetized rocks near the lunar surface, however, do create small, localized spots of magnetic field – small bubbles of magnetic “sunscreen” – that extend anywhere from hundreds of yards to hundreds of miles.

    Under these miniature magnetic umbrellas, the material that makes up the moon’s surface, called regolith, is shielded from the sun’s particles. As those particles flow toward the moon, they are deflected to the areas just around the magnetic bubbles, where chemical reactions with the regolith darken the surface. This creates the distinctive patterns of darker and lighter swirls that are so prominent they can be seen from Earth.

    Bottom line: Video on how the moon got its distinctive pattern of lighter and darker swirls.

    SpaceX’s Crew Dragon splashed down back on Earth, safely completing its mission
    Korey Haynes | Published: Friday, March 08, 2019

    The private space agency is one step closer to sending humans to space.


    SpaceX’s Crew Dragon capsule departed the International Space Station early Friday morning and began a series of thruster burns that steered the ship back toward Earth, where it safely splashed down in the Atlantic Ocean not long after 7:30 a.m. EST. The craft had been attached to the space station since Sunday, when it made its first docking under its own power after a successful Saturday launch atop a Falcon 9 rocket.

    This final phase of the Demo-1 mission was perhaps the biggest test of Crew Dragon’s new build. It had to successfully deploy an upgraded parachute system to land the more gently than the already proven cargo version. The parachute system in particular was under close scrutiny, since it will eventually be responsible for protecting human passengers.

    Flight tests

    The Dragon capsule that flew this week is not the final version that will fly in future tests, but it is close. At a pre-launch briefing, SpaceX Vice President of Build and Flight Reliability Hans Koenigsmann said that the company is still in the final stages of development on Crew Dragon’s internal controls.

    Since the only passengers on Demo-1 were a dummy named Ripley, an Earth plushie, and cargo, the controls weren’t necessary for this flight. But now that Crew Dragon has safely flown to space and back, it’s likely that real-life astronauts may soon take the helm.

    With NASA’s approval, SpaceX would proceed to a Demo-2 mission in July, where two astronauts will become the first to fly into space on a private craft. Before that, NASA and SpaceX will also run an abort test with the craft’s “Super Draco” thrusters. They’re designed to ensure the capsule can safely get humans back to Earth even if something goes wrong during or immediately after launch.

    Crew Dragon’s splash down in the Atlantic Ocean also included a full test run of the medical personnel that are always on stand-by for crew recovery after space mission landings. It marked the first time a spacecraft designed for humans has splashed down in the Atlantic since the Apollo 9 capsule did so in March 1969.

    Lake Michigan UFO sightings still unsolved 25 years later
    Dejanay Booth, Detroit Free Press Published 3:23 p.m. ET March 7, 2019 | Updated 5:26 p.m. ET March 7, 2019


    The eerie lights filled the sky along nearly 200 miles of Lake Michigan shoreline, from Ludington south to the Indiana border.

    On March 8, 1994, calls flooded 911 to report strange sightings in the night sky. The reports came in from all walks of life — from police and a meteorologist to residents of Michigan's many beach resorts. Hundreds of people witnessed what many insisted were UFOs — unidentified flying objects.

    Cindy Pravda, 63, of Grand Haven remembers that night in vivid detail — four lights in the sky that looked like "full moons" over the line of trees behind her horse pasture.

    "I got UFOs in the backyard," she told a friend on the phone.

    Today, the mystery of one of the largest UFO sightings in Michigan history remains unsolved, but it continues to fascinate extraterrestrial researchers, psychologists and history buffs alike.

    Pravda still believes the lights were UFOs.

    "I watched them for half an hour. Where I'm facing them, the one on the far left moved off. It moved to the highway and then came back in the same position," Pravda told the Free Press on Thursday. "The one to the right was gone in blink of an eye and then, eventually, everything disappeared quickly."

    She still lives in the same house and continues to talk about that night.

    "I'm known as the UFO lady of Grand Haven," Pravda laugh.

    Where it started

    Daryl and Holly Graves and their son, Joey, told reporters in 1994 they witnessed lights in the sky over Holland at about 9:30 p.m. on March 8.

    "I saw six lights out the window above the barn across the street," Joey Graves told the Free Press in 1994. "I got up and went to the sofa and looked up at the sky. They were red and white and moving."

    Others gave similar accounts, including Holland Police Officer Jeff Velthouse and a meteorologist from the National Weather Service Office in Muskegon County. What's more, the meteorologist recorded unknown echoes on his radar the same time Velthouse reported the lights.

    "My guy looked at the radar and observed three echoes as the officer was describing the movement," Leo Grenier of the NWS office in Muskegon said in 1994. "The movement of the objects was rather erratic. The echoes were there about 15 minutes, drifting slowly south-southwest, kind of headed toward the Chicago side of the south end of Lake Michigan."

    In 1995, The Free Press published the conversation between the National Weather Service and Velthouse.

    "What do you think it is?" said the weather service radar operator.

    Velthouse described witnesses seeing five to six objects, some cylindrical with blue, red, white and green lights.

    The radar operator said, "There were three and sometimes four blips, and they weren't planes. Planes show as pinpoints on the scope, these were the size of half a thumbnail. They were from 5 to 12,000 feet at times, moving all over the place. Three were moving toward Chicago. I never saw anything like it before, not even when I'm doing severe weather."

    Hundreds of reports of suspected UFOs were called in not only to 911 dispatchers but also to the Mutual UFO Network's (MUFON) Michigan chapter.

    MUFON, an all-volunteer nonprofit organization founded in 1969, bills itself as the "world's oldest and largest civilian UFO investigation and research organization."

    In 1994, the network received UFO reports from Ludington south to the Indiana state line, spokeswoman Virginia Tilly told the Free Press in 1994.

    "We're getting 10 or 15 new sightings a day," Tilly said. "We have probably 20 people in various stages of investigating these reports."

    The reported UFO sightings was the largest since March 1966, Bill Konkolesky, Michigan state director of MUFON, told the Free Press this week.

    "It was one of the big ones in the state. We haven't seen a large UFO (reported sighting) wave since that time," Konkolesky said.

    Konkolesky joined the network in 1993. He was not part of the investigation team but still has a copy of an article about the sightings with a picture of the Graves family on the front cover.

    MUFON interviewed dozens of witnesses, Konkolesky said, many of whom remain in contact with the organization.

    "There was a lot of enthusiasm into the UFO field (then) because of the amount of press coverage. It was outstanding," he said. "They were paying attention to the phenomenon."

    Konkolesky said the flying objects reported in 1994 are characterized as "unexplained" and the sightings remain a mystery.

    Not so far-fetched

    The idea of alien life isn't as farfetched as once thought, with a number of recent discoveries pointing raising the possibility.

    In a series of reports from USA TODAY, researchers have studied whether life could exist on a recently discovered "Super Earth" about 30 trillion miles away.

    Villanova University astrophysicists Edward Guinan and Scott Engle told USA TODAY that the planet, known as Barnard b, has a temperature of 274 degrees below zero, but "niches of life" may be possible under the ice.

    Another group of researchers is studying whether a mysterious object entering the Earth's solar system from interstellar space at a high rate of speed actually is a probe intentionally sent here by an alien civilization. Scientists later decided that the weird object actually was a comet.

    And another study reports that more “fast radio bursts" – bright, short-lived pulses of radio waves that come from across the universe — have been detected by astronomers. Some researchers have considered the idea that these bursts could be signals from intelligent aliens, according to Science News.

    Other mysteries

    The UFO frenzy of 1994 was one in a string of unexplained phenomena in Michigan history.

    In 2016, a mysterious phenomenon known as the Paulding Light was reported in the western Upper Peninsula.

    Witnesses reported seeing a bright white light, glowing deep inside the woods, changing size and shape before fading into the darkness. Although many individuals believed the flickering lights was because of a car driving over a hill, others believed it to be something supernatural and too bright to be headlights.

    Hubble's dazzling display of 2 colliding galaxies
    Science News: NASA/Goddard Space Flight Center| March 11, 2019

    Located in the constellation of Hercules, about 230 million light-years away, NGC 6052 is a pair of colliding galaxies first discovered in 1784. A long time ago gravity drew the two galaxies together into the chaotic state we now observe.

    Located in the constellation of Hercules, about 230 million light-years away, NGC 6052 is a pair of colliding galaxies. They were first discovered in 1784 by William Herschel and were originally classified as a single irregular galaxy because of their odd shape. However, we now know that NGC 6052 actually consists of two galaxies that are in the process of colliding. This particular image of NGC 6052 was taken using the Wide Field Camera 3 on the NASA/ESA Hubble Space Telescope.

    A long time ago gravity drew the two galaxies together into the chaotic state we now observe. Stars from within both of the original galaxies now follow new trajectories caused by the new gravitational effects. However, actual collisions between stars themselves are very rare as stars are very small relative to the distances between them (most of a galaxy is empty space). Eventually the galaxies will fully merge to form a single, stable galaxy.

    Our own galaxy, the Milky Way, will undergo a similar collision in the future with our nearest galactic neighbor, the Andromeda galaxy. However, this is not expected to happen for around 4 billion years.

    This object was previously observed by Hubble with its old Wide Field and Planetary Camera 2 (WFPC2). That image was released in 2015.

    Small asteroid to sweep closer than moon’s distance
    Eddie Irizarry in SPACE | March 13, 2019

    The house-sized asteroid – designated 2019 EA2 – will pass safely by our planet on the night of March 21-22, 2019.

    According to clocks in the Americas, a house-sized asteroid will pass safely by our planet on the night of March 21, 2019. For other parts of the world, the pass will come on March 22. The newly discovered asteroid has been designated as 2019 EA2. The Mt. Lemmon Survey in Arizona first spotted it on March 9, 2019.

    According to NASA, 2019 EA2’s closest approach to Earth will occur on the night of Thursday, March 21, 2019, at 9:32 p.m. EDT (01:32 UTC March 22; translate UTC to your time). The small asteroid will pass closer than the moon, at 189,923 miles (305,652 km) from Earth or 0.8 lunar distances.

    The space rock has an estimated size of 75 feet (23 meters) in diameter, which means it’s slightly larger than the asteroid that penetrated the atmosphere over the skies of Chelyabinsk, Russia, on February 15, 2013. That asteroid – estimated to be 55 feet (17 meters) in diameter – caused a shock wave that broke windows in six Russian cities and caused some 1,500 people to seek medical attention.

    2019 EA2 is an Aten type – or Earth-crossing – space rock. Its orbit brings it between the orbits of planets Venus and Earth.

    It is traveling through space at a speed of 12,027 miles (19,355 km) per hour or 5.38 km (3.3 miles) per second.

    Bottom line: A house-sized asteroid – designated 2019 EA2 – will pass safely by our planet, closer than the moon’s distance, on March 21-22, 2019.

    NASA selects nine teams to study unopened Apollo moon samples
    Astronomy Now, 12 March 2019

    NASA has selected nine research teams to analyse pristine samples of lunar soil returned to Earth by the Apollo astronauts and left untouched for the past five decades. The U.S. space agency has allotted $8 million for the research under the Apollo Next Generation Sample Analysis program, or ANGSA.

    “When the previous generations did Apollo, they knew that the technology they had in that day was not the technology we would have in this day,” said NASA Administrator Jim Bridenstine. “So they (decided) to preserve samples, because they knew there would be a day when better technology would be able to better assess the history of the moon.”

    Bridenstine made the announcement while unveiling NASA’s $21.5 billion 2020 budget request from the Trump administration, a budget that supports the agency’s plans to return astronauts to the moon by 2028.

    “We have nine teams that will be examining nine unopened samples that have come back from the moon,” the administrator said. “We feel like we can do that because there are more lunar samples on the horizon where we’re going to be able to learn more than we’ve ever learned about the moon before. So I’d like to thank the Apollo generation for preserving these samples so that our generation can have this opportunity.”

    The samples were collected during the Apollo 15, 16 and 17 missions. An Apollo 17 sample, for example, will be studied by the University of New Mexico’s Institute of Meteoritics, which will receive about 800 grams (1.8 pounds) of material from a core sample that was sealed in a vacuum container on the surface of the moon.

    The team will measure the chemical constituents of the sample and “prepare us to explore and sample potential resources for future human activities,” said research assistant Charles Shearer. “Further, this will be the first analysis of a core through a lunar landslide deposit and will further our understanding of the timing, triggers, and dynamics of these events. The deposit may contain new lunar rocks never sampled before.”

    Another sample will be assessed by Darby Dyar at the Planetary Science Institute.

    “This project brings massive state-of-the-art synchrotron and infrared analysis to bear on tiny lunar samples to unlock the secrets of the lunar interior,” said Dyar, a senior scientist at PSI. “We will use state-of-the-art synchrotron technology and a mapping FTIR spectrometer to measure gradients of volatiles * hydrogen and oxygen – preserved in lunar glass beads.”

    Such beads are formed by “rapid cooling of droplets from explosive lunar fire fountains, like those seen in Hawaii,” she said. “We will map changes from core to rim that reveal hydrogen and oxygen pressures in the lunar interior and before, during, and after eruption.”

    Another research team, led by Jessica Barnes, an incoming assistant professor at the University of Arizona’s Lunar and Planetary Laboratory, will look for traces of water in a 110-gram (4 ounce) sample that was collected by the Apollo 17 crew. Like the other samples, the soil was moved into a freezer within a month of the astronauts’ return.

    “The question we want to answer is, are we measuring the true Moon signature? Or are there terrestrial influences that have affected the samples during their storage?” Barnes said. “The beauty of a frozen sample is that it’s been kept curated in a different way from the samples stored at room temperature. We could not do this research without opening the frozen samples.”
