NASA loaded more than three-quarters of a million gallons of super-cold propellant into the first Space Launch System moon rocket Monday in Florida, achieving key milestones in a practice countdown but falling short of all the test objectives after discovering a new hydrogen leak.
Want to Own a Meteorite from Geoff Notkin’s Personal Collection?
For nearly 30 years Geoff Notkin has traveled the world in search of meteorites, those ancient relics from outer space that have fallen to Earth. He shared his adventures on the Science Channel series “Meteorite Men,” and through lectures and appearances across almost every continent, he has sparked interest in space science and exploration. He has been a devoted meteorite hunter and collector, amassing a large collection. But now, after much deliberation, Notkin has decided to auction off some of his personal meteorite collection, as well as other personal items.
Samples of Asteroid Ryugu Contain More Than 20 Amino Acids
In 2014, the Japan Aerospace Exploration Agency (JAXA) dispatched its Hayabusa2 spacecraft to rendezvous with 162173 Ryugu, a Near-Earth Asteroid (NEA) that periodically passes close to Earth. In 2018, this sample-return mission reached Ryugu and spent the next year and a half studying its surface and obtaining samples from its surface and subsurface. By 2020, these samples made it back to Earth, where scientists began analyzing them in the hopes of learning more about the early history of the Solar System and answering key questions about the origins of life.
Astronomers Watched a “Near-Sun” Comet Disintegrate as it Flew too Close to the Sun
Comets that venture close to the Sun can transform into something beautiful, but sometimes they encounter incineration if they get too close. Of the various types of comets that orbit close to the Sun, astronomers had never seen the destruction of the type classified as “near-Sun” comets. But thanks to a variety of telescopes on summit of Mauna Kea in Hawai?i, scientists have now captured images of a periodic rocky near-Sun comet breaking apart. They say the disintegration of this comet could help explain the scarcity of such periodic near-Sun comets.

Once Again, Galaxies Look Surprisingly Mature Shortly After the Beginning of the Universe
A young galaxy with the catchy, roll-off-the-tongue name A1689-zD1 has experts in galactic formation talking. Recent observations show that this galaxy, seen as it would have looked just 700 million years after the Big Bang, is larger than initially believed, with significant outflows of hot gas from its core, and a halo of cold gas emanating from its outer rim. A1689-zD1 is considered representative of young ‘normal’ galaxies (as opposed to ‘massive’ galaxies), and the new observations suggest that the adolescence of normal galaxies may be more rambunctious than previous models suggest.

NASA tries again to complete moon rocket’s practice countdown
STORY WRITTEN FOR CBS NEWS & USED WITH PERMISSION

Credit: NASA/Ben SmegelskyCountdown clocks began ticking Saturday for NASA’s fourth attempt to complete a dress-rehearsal countdown and fueling test of its Space Launch System moon rocket, a requirement before the huge booster can be cleared for launch on its long-awaited maiden flight.
“There’s nobody that wants to get through this more than the EGS (Exploration Ground Systems) team, and all of our teams … to get this vehicle tanked, understand where we get to in the terminal count and then get back … out for launch,” said Jim Free, director of exploration development at NASA Headquarters.
The countdown began at 5:30 p.m. EDT and if all goes well, the two-day test will tick into its final hours Monday morning when engineers plan to remotely load the rocket’s first and second stages with three quarters of a million gallons of supercold liquid oxygen and hydrogen fuel.
Launch Director Charlie Blackwell-Thompson and her team plan to count down to T-minus 33 seconds and then carry out a recycle that will mimic an unplanned hold before counting all the way down to just inside T-minus 10 seconds. At that point, just before the rocket’s four main engines would begin their start-up sequence in an actual launch, computers will stop the test.
The goal is to make sure complex launch control software, the rocket’s electrical, mechanical and propellant systems, along with their interfaces with launch pad support equipment, will work together as required to safely launch the most powerful booster ever built for NASA.
Those complexities were on display in three previous attempts to fuel the SLS as engineers ran into problems with launch pad subsystems, unexpected propellant temperature and pressure excursions, a jammed upper stage helium valve and leaks in a fitting that connects a hydrogen fuel line to the rocket’s first stage.
Originally hauled out to pad 39B at the Kennedy Space Center on March 18, NASA moved the 330-foot-tall SLS rocket back to the Vehicle Assembly Building on April 25 to replace the helium valve, fix the hydrogen leak and carry out several other upgrades and improvements.
Hydrogen leaks are notoriously hard to pinpoint and eliminate because they typically don’t show up until the hardware is exposed to cryogenic temperatures. But Free is optimistic that work to tighten up a flange in the fuel line connector has resolved the problem.
“We fixed some things we saw around the area where we saw the leak, including going back to some of the procedures we used and the know how from the shuttle days, which we really benefited from,” he said. “Obviously, we won’t know the results of that until we actually flow the liquid hydrogen at the pad.
“We also worked on some of the loading procedures,” he continued. “We saw some things with LOX (liquid oxygen) and hydrogen that our team was actually able to go back in (and) automate those procedures, which we know will help us during the upcoming flow.”
Along with addressing the hydrogen leak, engineers replaced the helium valve after finding a bit of rubber debris lodged in the mechanism. They also modified fueling procedures to eliminate some of the pressure and temperature issues experienced earlier.
Mounted atop a powerful crawler-transporter, the SLS rocket and its mobile launch stage were hauled back out to the launch pad June 6, setting the stage for this weekend’s fourth attempt to complete the rehearsal.
Assuming the test goes well, NASA will move the rocket back to the VAB one more time for final flight preparations.
NASA hopes to finally launch the SLS in late August, boosting an unpiloted Orion crew capsule on a test flight beyond the moon and back. The first piloted mission, a flight carrying four astronauts around the moon, is planned for 2023 with a landing in the 2025 timeframe.
