It appears we will need to wait until next month for the Artemis II launch due to a liquid hydrogen leak during the wet dress rehearsal. As a result, the four astronauts can come our of quarantine and rejoin their families.

In its blog, NASA noted other issues as well:

In addition to the liquid hydrogen leak, a valve associated with Orion crew module hatch pressurization, which recently was replaced, required retorquing, and closeout operations took longer than planned. Cold weather that affected several cameras and other equipment didn’t impede wet dress rehearsal activities, but would have required additional attention on launch day. Finally, engineers have been troubleshooting dropouts of audio communication channels across ground teams in the past few weeks leading up to the test. Several dropouts reoccurred during the wet dress rehearsal. 

Such issues are not unusual, so we will just have to be patient. We are almost there.

As NASA Administrator Isaacman noted on Twitter:

This is just the beginning. It marks the start of an Artemis program that will evolve to support repeated and affordable missions to the Moon…Getting this mission right means returning to the Moon to stay and a future to Artemis 100 and beyond.

Space Stories: Another Artemis II Delay, AI Discovers Cosmic Oddities in Hubble Data, and AI Drives a Martian Rover

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.

Podcast: We Need To Talk About AI

The recent Cool Worlds Podcast is basically a rambling talk about the use of AI in the scientific community. Titled “We Need To Talk About AI,” this dialogue by Professor David Kipping follows his visit to the Institute of Advanced Study at Princeton where he heard about how his colleagues are using AI in their work.

Professor Kipping covers many points and makes it clear from the start that he has some serious questions about the impact of AI on his own work and the work of graduate students. For instance, he asks:

  • Will cheap AI change the science community’s need need for graduate students in the future given the time and cost to develop those new scientists compared to the amazing advances in AI?
  • Will the cheap AI program of today become more costly down the road once the AI companies need to recoup the billions of dollars invested in this technology?
  • Will science become too dependent on this technology while human skills atrophy?

He is also very honest about how he uses AI in the production of his own public videos explaining scientific developments and controversies. More interestingly, he wonders aloud whether we will even need his videos in the future as AI gets better and we have the ability to seek our own answers rather than waiting for the next video.

It’s a lot to digest and worth your time, if only because it is an ongoing set of questions in basically every industry at this point.

Listen for yourself and consider giving your own input back to Professor Kipping. He is soliciting your opinion as he finds his way forward in this new world.

Study Findings: A Binary Model of Long-Period Radio Transients and White Dwarf Pulsars

Nature Astronomy abstract of study findings:

Long-period radio transients (LPTs) represent a recently uncovered class of Galactic radio sources exhibiting minutes to hours periodicities and highly polarized pulses of seconds to minutes duration. Their phenomenology does not fit exactly in any other class, although it might resemble that of radio magnetars or white dwarf (WD) pulsars. Two LPTs with confirmed multi-wavelength counterparts have now been identified as WD – M dwarf binaries. Moreover, WD pulsars (also WD – M dwarf systems), such as AR Scorpii and J1912−44, are known to exhibit short-period pulsations in hour-timescale orbits. Here we investigate the longest-lived LPT known, GPM J1839−10. We use a 36-year timing baseline to infer an ~8.75-h orbital period from radio data alone, and we show that it can be modelled in the same geometric framework as has been proposed for WD pulsars. Radio emission is triggered when the magnetic axis of a rotating WD intersects the wind from its companion, which naturally predicts the peculiar pulse modulation. Applying this to the WD pulsar J1912−44 successfully reproduces the emission profile and geometry as well. Our results indicate analogous emission-site geometries in these related classes of binary system, a possibility we extend to the broader LPT and WD pulsar population.

Artemis II Mission Delayed by NASA

The cold weather on the East Coast continues to cause problems, this time for NASA and its planned launch of the Artemis II mission, which will take astronauts around the Moon. Originally scheduled for February 6th, the mission is being delayed two more days until February 8th to allow NASA more time for its wet dress rehearsal, otherwise known as its comprehensive pre-launch check. In the meantime, the four astronauts assigned to the mission will remain in quarantine.

Earlier today, NASA stated:

Over the past several days, engineers have been closely monitoring conditions as cold weather and winds move through Florida. Managers have assessed hardware capabilities against the projected forecast given the rare arctic outbreak affecting the state and decided to change the timeline. Teams and preparations at the launch pad remain ready for the wet dress rehearsal. However, adjusting the timeline for the test will position NASA for success during the rehearsal, as the expected weather this weekend would violate launch conditions.

It has already been an unusual winter, so none of this is a great surprise.

Fingers crossed for some warmer weather so NASA can complete this mission and then eventually land humans on the Moon once again with the next mission – Artemis III.
