“At the moment, we are finalizing our agreement with NASA, but it is looking like they are not able to provide the radar…So that is why we are going full steam ahead with the European solution.”
–Statement by Anne Grete Straume-Lindner, the European Space Agency’s (ESA) project scientist for the Venus mission called Envision, regarding expected cuts in NASA support for the planned Venus mapping mission. Proposed NASA cuts may also impact other ESA missions, including the New Athena observatory, which would take over for NASA’s Chandra X-ray Observatory (also continually on the chopping block) and the Laser Interferometer Space Antenna (LISA) observatory designed to study gravitational waves.

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.
NASA has decided to use a simpler spacesuit for its initial missions to the lunar surface, Ars has learned. The agency announced the decision during an internal meeting this week as it seeks to accelerate its program to land humans at the south pole of the Moon as early as 2028. At the direction of Artemis Program Manager Jeremy Parsons, NASA will work with Axiom Space to develop a “Sortie Suit” variant of the planned spacesuit for the lunar surface. Sources said the Sortie Suit will be used for the initial landing missions flown on landers developed both by SpaceX and Blue Origin. Among the goals of the initiative are to lower the mass of the spacesuit, reduce its complexity, and simplify interfaces between the spacesuits and lunar landers.
The driving force behind our universe’s accelerated expansion remains one of the greatest mysteries in astronomy. While this force, which scientists refer to as dark energy, pervades our universe, we know almost nothing about it. Located on a remote mountain in Arizona’s Sonoran Desert, the Dark Energy Spectroscopic Instrument (DESI) has spent the past five years mapping the cosmos with the goal of unraveling this mystery. The result is the largest three-dimensional map of the universe ever created. And now—with the release of the latest version of the DESI Legacy Imaging Surveys, a free online tool for exploring the vast imaging data—you too can poke around the universe.
Over the past three decades, computer models of planetary system formation have gone from fairly crude representations to sophisticated simulations using thousands of different starting points. A paper presented at the Origins 2026 conference in Paris details innovative simulations of how our solar system might have formed without making assumptions about the planetary architecture with which we are so familiar. In his paper, Nader Haghighipour, a planetary scientist at the University of Hawaii in Manoa, argued that his models, unlike previous models, incorporate many completely random starting points and, in turn, let physics drive the models’ ultimate evolution. As a result, these new models are much more complete and allow physics to dictate their outcomes.

“[Mars Telecommunications Orbiter] is the backbone of America’s Mars exploration program for the next decade and beyond and will provide the reliable communications capacity that will keep future robotic and human missions connected to each other and to Earth…This awarded contract is a testament to the Blue Origin team that has been building Blue Ring with exactly this kind of mission in mind. We’re ready, and so is the hardware.”

Talk about eerie. This week’s image is from the NASA/European Space Agency’s (ESA) Hubble Space telescope. The ghostly image shows nebula LHA 120-N44, or N44, which is about 160,000 light-years away. It is within the Large Magellanic Cloud that orbits our galaxy.
Here is more from NASA describing what you are seeing:
N44 is dominated by two features: a vast central void and a shell of dense, dusty gas. The central void is a ‘superbubble’ spanning roughly 210 by 140 light-years across. The glittering stars at the center of the void are responsible for its creation; through their powerful stellar winds and explosive supernovae, these stars expelled much of the gas from which they were born.
When the stars of N44’s central star cluster swept away this gas, the expelled gas compressed and formed a shell around the superbubble. New stars are forming in this compressed gas shell, making N44 an interesting target for astronomers who are using the nebula to study how stars form in this environment. Their goal is to understand how long it takes from the collapse of cold gas clouds into dense knots to the moment nuclear fusion ignites in the heart of a newborn star.
