“Our team is not trying to replace human explorers with robots but instead make human exploration safer and more sustainable by developing highly capable, reliable, and trustworthy robots to work in extreme environments…If we can send more capable robots, we can reduce the risk and make people more effective in doing the things that people do best.”
-Statement by Shaun Azimi, NASA’s Dexterous Robotics Team lead. The 16-member Dexterous Robotics Team at NASA’s Johnson Space Center in Houston includes team member who had experience with earlier robot experiments, including Robonaut 2, used on the International Space Station, and Valkyrie, which is NASA’s first bipedal humanoid robot. Future robots are expected to assist with the Moon Base, lunar exploration, and eventually greater work on Mars (beyond the rovers and helicopter already on the Martian surface). This means that artificial intelligence (AI) will be heading to the moon as well while we still try to figure out what to do with AI back here on Earth. AI is already being used on the Martian surface with the Perseverance and Curiosity rovers.

A new ∼222-meter-diameter impact crater formed on the Moon in spring 2024. Discovered in repeat Lunar Reconnaissance Orbiter Camera images, it provides a unique opportunity to study surface modification by a pristine impact, prior to subsequent fading. Nighttime temperatures measured by the Diviner instrument reveal an ∼7-kilometer-wide cold spot that is 8 to 9 kelvin cooler than its surroundings, consistent with decompaction of the upper centimeters to decimeters of regolith. We investigate all newly formed craters >20 meters identified to date and find that all craters larger than ∼30 meters produce detectable cold spots, indicating that cold spot formation is a common consequence of fresh lunar impacts. Cold spot temperature anomaly increases with crater size, implying deeper regolith modification around larger craters. This scaling suggests that the cumulative effect of cold spot formation may modify the shallow regolith at rates comparable to impact gardening by primary craters, making them a substantial driver of regolith evolution on regolith-covered airless bodies.

“It’s not like they’re writing the show and then having to come up with, ‘Oh, how to end this?’…This is a 40 episode story. So the ending… is very satisfying because it’s the end of a novel.”
–Statement by actor Ashley Zukerman, who plays Daniel Keene in the Silo television series, regarding the fourth and final season of the series coming out on July 9, 2027. If you missed the series, particularly season three, it is a show you need to watch. We talk about living in lava tubes on the Moon or Mars, but this show is about living in an underground silo for generations here on Earth after some pretty horrible terra-forming above. You can catch it on Apple TV.
German rocket maker Isar Aerospace successfully reached orbit for the first time over the weekend, marking a milestone for Europe’s commercial space industry as the company looks to ramp up launches to meet what it says is booming demand. The Munich-based company’s Spectrum rocket reached orbit on Saturday and successfully deployed its payloads in low Earth orbit, an achievement that came on only its second test flight. Chief Commercial Officer Stella Guillen told CNBC on Monday that the company was now focused on scaling production, saying the space industry was “desperate” for additional launch capacity and that Isar had a pipeline worth more than 10 billion euros ($11.6 billion).
It is thought the Sun may have engulfed a super-Earth-sized planet early in its history. Now a new study has gone a step further by suggesting that such an event may have left behind detectable clues inside our star which could still be visible today. This idea of a measurable signature or ‘fingerprints’ in the present-day solar interior was explored by research published today in Monthly Notices of the Royal Astronomical Society. Professor Mutlu Yildiz, of Ege University in Turkey, said: “Our new study suggests that a planet several times more massive than Earth may have fallen into the young Sun and left a lasting chemical imprint deep inside it.
Some countries and even wealthy individuals are setting their sights on the Moon with ambitious plans to create a lunar colony. That would require a lot of resources launched from Earth, but how much water and power would be required to keep a lunar city going?…Even assuming one billion tonnes of water on the Moon, if nothing was recycled then a city of a million would last only a few years while a population of 100 000 would run for 20 years before running dry. Even when recycling the water with an efficiency of 98% – as performed on the International Space Station – a city of a million would only have enough water for around a century.

Four astronauts circled the Moon earlier this year, more than 50 years after the final lunar landing, but only one of them will remain an astronaut going forward. Canadian astronaut Jeremy Hansen (age 50), who served as mission specialist on the Moon mission, retired from his position with the Canadian Space Agency in July. And now we learn that NASA astronauts Reid Wiseman (age 50), who served as commander on the mission, and Victor Glover (age 50), who served as pilot, have also announced their plans to depart as well.
Either there is something in the water, or age 50 is a good time to step away from an astronaut gig.
Hansen said he was pursuing new professional opportunities, Glover said he has a new job at California Polytechnic State University, and Wiseman provided no additional information. However, both Glover and Wiseman will transition to emeritus status. It is not clear if that is just a thank you role that gives them a discount at the agency cafe, or will entail some real duties.
NASA defines the emeritus role this way:
In an emeritus role, individuals with a high degree of technical and professional knowledge can continue to support the agency by donating their time to train and mentor the current workforce. This allows the agency to maintain access to top talent in a specialized consultant role, while simultaneously providing the individual with the flexibility to pursue other opportunities.
That leaves one Artemis II astronaut still standing – Christina Koch (age 47).
Back in August, all four were awarded the Congressional Space Medal of Honor at Houston’s Johnson Space Center. It is just unfortunate the they are leaving at a time that a lunar program is starting to grow.
All we can do is wish them well in their post-astronaut careers. They have plenty of stories that will hopefully encourage a new generation of astronauts.
Note: I want to make it clear that NASA astronauts do not need to retire at a certain age. For example, NASA astronaut Don Pettit was heading back to Earth from his latest space mission on his 70th birthday.
