Here are some recent space-related stories of interest.

—CBS News: “Artemis II Moon Rocket Fueling Test Runs into Problems with Hydrogen Leak“

A hydrogen leak at the base of NASA’s Artemis II moon rocket Monday threw a wrench into a carefully planned countdown “wet dress” rehearsal, but engineers were able to manage a workaround and the test proceeded toward a simulated launch. Whether mission managers will be able to clear the rocket for an actual launch as early as Sunday to propel four astronauts on a flight to the moon will depend on the results of a detailed overnight review and post-test analysis. NASA only has three days — Feb. 8, 10 and 11 — to get the mission off this month or the flight will slip to March.

—ZME Science: “Astronomers Unleashed an AI on Hubble’s Archive and Uncovered 1,300 “Cosmic Oddities.” Most Were Completely New to Science“

For more than three decades, the Hubble Space Telescope has collected targeted images to answer specific scientific questions, from mapping galaxies to studying nearby nebulae. Hubble has gathered so much data that despite their best efforts, astronomers haven’t had the time to analyze it all in detail yet…Now, two astronomers have revisited that massive archive with a new plan. They deployed an artificial intelligence system designed to notice when something looks “wrong”. In just 60 hours of computing time, the tool flagged over 1,300 anomalies hidden within 100 million Hubble snapshots. Hundreds of them have never appeared in scientific literature.

—NASA/JPL “NASA’s Perseverance Rover Completes First AI-Planned Drive on Mars“

NASA’s Perseverance Mars rover has completed the first drives on another world that were planned by artificial intelligence. Executed on Dec. 8 and 10, and led by the agency’s Jet Propulsion Laboratory in Southern California, the demonstration used generative AI to create waypoints for Perseverance, a complex decision-making task typically performed manually by the mission’s human rover planners…During the demonstration, the team leveraged a type of generative AI called vision-language models to analyze existing data from JPL’s surface mission dataset. The AI used the same imagery and data that human planners rely on to generate waypoints — fixed locations where the rover takes up a new set of instructions — so that Perseverance could safely navigate the challenging Martian terrain.

Space Stories: Moon Kills Earth Water Theory, Astronauts in Quarantine, and China Loses Two Rockets

—Universities Space Research Association: “Our Moon’s 4 Billion-Year Impact Record Suggests Meteorites Didn’t Supply Earth’s Water“

A long-standing idea in planetary science is that water-rich meteorites arriving late in Earth’s history could have delivered a major share of Earth’s water. A new study by Universities Space Research Association (USRA) and University of New Mexico argues that the Moon’s surface record sets a hard limit on that possibility: even under generous assumptions, late meteorite delivery since about 4 billion years ago could only have supplied a small fraction of Earth’s water...In a paper published in the Proceedings of the National Academy of Sciences, researchers led by Dr. Tony Gargano at USRA’s Lunar and Planetary Institute and the University of New Mexico analyzed a large suite of Apollo lunar regolith samples using high-precision triple oxygen isotopes. Earth has erased most of its early bombardment record through tectonics, and constant crustal recycling. The Moon, by contrast, preserves a continuously accessible archive: lunar regolith, the loose layer of debris produced and reworked by impacts over billions of years

—Florida Today: “NASA Artemis Astronauts in Quarantine Ahead of Rocket Launch in Florida“

The four astronauts who will soon become the first humans in more than half a century to fly on a lunar mission have begun the quarantine process – a crucial sign that NASA believes a launch could be imminent. Sequestering themselves away from others for the next several days ensures that the three Americans and one Canadian selected for a mission known as Artemis 2 are at low risk of becoming sick and jeopardizing the mission. The crew members have entered quarantine in Texas as NASA makes final preparations in Florida to ready the towering rocket that will get the mission off the ground as early as February.

—Technology.org: “China’s Space Ambitions Hit Turbulence: Two Rockets Fail Within 12 Hours“

The Long March 3B departed Xichang Satellite Launch Center in southwest China at 11:55 Eastern (1655 UTC) on January 16. Amateur footage confirmed the rocket left the pad on schedule. Then came silence. The China Aerospace Science and Technology Corporation (CASC) waited nearly 12 hours before acknowledging what observers already suspected. “The specific cause is under further analysis and investigation,” state media Xinhua reported…Less than 12 hours after the Long March 3B failure, Galactic Energy attempted something the company had been working toward for months: the first flight of its Ceres-2 rocket. After repeatedly postponed launch windows, the solid-fueled rocket finally lifted off from Jiuquan Satellite Launch Center at 11:08 p.m. Eastern on January 16 (0408 UTC, January 17). It didn’t work. Galactic Energy confirmed an anomaly had occurred and that investigation was underway.

Space Quote: Ongoing Questions about the Orion’s Heat Shield

Crewed Mission to Lunar Orbit (IG-24-011)

“What they’re talking about doing is crazy…We could have solved this problem way back when…Instead, they keep kicking the can down the road.”

-Statement by former astronaut Charlie Camarda, who does not believe the upcoming Artemis II mission is safe for the astronauts given his concerns about the Orion’s heat shield, as quoted by CNN. The news story cites others who state that the Orion heat shield issue has been resolved and the mission is ready to go. The Artemis II mission is set to launch as early as February 6th.

Space Stories: A Dead Galaxy, Newly Discovered Cloud-9, and Preparing for Artemis II

—innovation News Network: “Astronomers Discover Ancient “Dead Galaxy” Starved by its Supermassive Black Hole“

Using observations from the James Webb Space Telescope (JWST) and the Atacama Large Millimeter Array (ALMA), researchers found that a growing supermassive black hole can slowly starve a galaxy rather than destroy it outright. The galaxy, catalogued as GS-10578 and nicknamed Pablo’s Galaxy, existed just three billion years after the Big Bang. Despite this early stage in cosmic history, it is enormous – around 200 billion times the mass of the Sun. Most of its stars formed between 12.5 and 11.5 billion years ago, indicating a rapid burst of star formation before the galaxy suddenly shut down.

—CNN: “‘Cloud-9’ is a Newly Discovered Celestial Object. It Could Help Solve a Cosmic Mystery“

Astronomers may have discovered a previously unknown type of astronomical object, nicknamed “Cloud-9,” that could shed light on dark matter, one of the biggest mysteries in the universe. …Cloud-9 is thought to be a dark matter cloud that could be a remnant of galaxy formation from the early days of the universe, according to new research published Monday in The Astrophysical Journal Letters.

—Space.com: “NASA to Roll Out Rocket for Artemis 2 Moon Mission on Jan. 17“

The first crewed moon mission in more than 50 years remains on track to launch as soon as Feb. 6. NASA announced on Friday evening (Jan. 9) that it plans to roll the Space Launch System (SLS) rocket and Orion spacecraft that will fly the Artemis 2 moon mission out to the pad for prelaunch checks on Jan. 17, weather and technical readiness permitting.

Podcast: Does the Younger Generation Even Care about Returning to the Moon?

Posted on by onespaceman2000

In a recent episode of What Next: TBD, titled “Are We Over the Moon?,” the host spoke with Joel Achenbach, freelance journalist and author of an article in Slate called Moondoggle about the upcoming Artemis missions.

The discussion covers the plans for multiple missions to the Moon, the difference in generational interest, and the confusion last year about NASA’s leadership and budget that only brings up more questions.

Overall, Mr. Achenback does not believe the younger generations have much interest in a mission to the Moon. This is a scary statement at a time that NASA is fighting to remain funded and relevant.

It is a podcast (and article) with lessons for NASA’s public relations team, assuming anyone over there is interested.
