The commander and pilot of NASA's Artemis II mission have gained a new distinction five months after splashing down from the Moon: They're not fully retiring from the space agency.
Reid Wiseman and Victor Glover are the first astronauts to join NASA's emeritus program, enabling them to continue to support the work being done at Johnson Space Center in Houston. They will remain available to train and mentor the current workforce while still being able to pursue employment and opportunities outside of NASA.
"I have asked NASA ... to not use the term 'retire' as much, but technically emeritus is a retirement program," Glover told collectSPACE.com on Wednesday. "It's something we have typically done for scientists when they have groundbreaking research, and they want to go back to academia to teach or to research and publish."

NASA and Roscosmos have agreed to continue exchanging seats between Soyuz and Crew Dragon spacecraft, but that agreement does not yet extend to Starliner.

NASA breathed a deep sigh of relief six years ago when SpaceX launched two astronauts, Doug Hurley and Bob Behnken, on a successful mission to the International Space Station. With the safe landing of Crew Dragon, the US space agency broke a nearly decade-long gap in its ability to put humans into orbit.
Through its Commercial Crew program and multibillion-dollar contracts awarded in 2014, NASA had hoped to foster two providers of low-Earth orbit transportation, SpaceX and Boeing. However Boeing has yet to complete a successful crewed test flight—a perilous 2024 test flight by Boeing's Starliner was later declared a Type A mishap—and probably won't fly another crewed mission before 2028.
With the International Space Station slated for retirement in the early 2030s, NASA is partnering with several US companies to develop private space stations. As part of that effort, the private companies will have to work with NASA to determine how they will transport astronauts to and from their space stations, some of which could launch as soon as 2030.

Homo floresiensis, a diminutive ancient hominin often compared to the hobbits of J.R.R. Tolkien’s Lord of the Rings mythos, engaged in a sort of “second breakfast” according to new research.
Instead of eating twice in short succession like their fictional counterparts, a new paper published in Nature Microbiology suggests that these hobbits were second to the table, eating the scavenged remains of Komodo dragon kills. This new work challenges earlier suggestions that H. floresiensis was a sophisticated species capable of using fire and hunting large game.
H. floresiensis remains have been discovered co-located with proboscideans, the taxonomic group that includes elephants, stegodons, and similar trunked creatures. One such discovery occurred on the island of Flores, off the coast of Indonesia, at the Liang Bua site.
Among the H. floresiensis and Stegodon remains at the site, small stone tools littered the area, leading researchers to conclude that the hobbits were ancient hunters.
The isolated conditions of the small island produced one of the most dwarfed Stegodon breeds, typically standing just under four feet tall and weighing between 770 and 800 pounds. In comparison, the hobbits were only a bit over three feet tall and weighed around 66 pounds, with the two species together forming almost a miniature scale model of the big-game hunting that later hominins would engage in elsewhere in the world.
Archaeologists identified Stegodon remains bearing char marks, which they interpreted as evidence that the small hominins had mastered fire and were cooking their food. This was an unexpected find, as H. floresiensis was a relatively small-brained species, while evidence of fire use has typically been identified only in larger-brained species such as modern humans and Neanderthals.
The suggestion that the tiny, small-brained creatures killed and cooked Stegodon and other elephant ancestors led scientists to believe the species was relatively advanced. Potentially supporting this contention were skull measurements, indicating that despite the relatively small brain size, there was an expansion of the brain’s frontal polar region, associated with high-level cognitive processing. Taken together, this evidence led researchers to suspect that the hobbits were far more sophisticated than they had previously been given credit for.
However, when Smithsonian researchers reexamined the Stegodon bones found on Flores, they came to a different conclusion. Only one other creature on the island was a large enough predator to take down a Stegodon: the Komodo dragon. The Smithsonian team set out to investigate who was really behind the Stegodon kills: tiny hobbits, or giant lizards.
First, they performed an experiment at Zoo Atlanta, feeding Komodo dragons and then measuring the tooth marks on the leftover bones. Based on these baseline measurements, the researchers discovered Komodo dragon tooth marks on the meatiest, and therefore, most desirable parts of the carcass for predators to consume. It was only on the less desirable portions of the Stegodon remains that the team found cut marks likely caused by the hobbits.
This indicates that Komodo dragons were most likely the original predators who killed the Stegodon, quickly taking the prime portions, with H. floresiensis coming later, like a hyena, to scavenge the remains.
Additionally, their reinvestigation of H. floresiensis’s use of fire also called into question prior assertions. Only one of 3155 Stegodon bone fragments showed any evidence of contact with fire. That one fragment was unearthed high in the strata and may have poked through the surface of the site when it was used as a hearth by later H. sapiens, explaining the one odd incidence of fire damage.
In their final conclusion, the authors write, “The evidence to date thus suggests that H. floresiensis did not engage in a behavioral repertoire as diverse or as flexible as in modern humans or Neanderthals, possibly due to an ancestry in which large game hunting and controlled use of fire did not evolve”
The paper, “Taphonomic analysis at Liang Bua Reveals the Behavioral and Technological Capabilities of Homo Floresiensis,” appeared in Science Advances on July 3, 2026.
