NASA Weighs Early ISS Crew Return After Medical Issue Cancels Spacewalk NASA is considering an unusually early return of an International Space Station crew member after cancelling a planned spacewalk due to a medical concern. The move matters as it underscores the agency’s cautious approach to astronaut health and mission safety in orbit. NASA said the issue involves one astronaut whose condition is stable aboard the ISS, prompting the agency to halt a spacewalk scheduled for Thursday while assessments continue.

Transportation Secretary Sean Duffy, known for disliking NYC subways, is NASA's interim administrator. President Trump announced the appointment after withdrawing Jared Isaacman's nomination. #NASANews #News

Some relatively positive news from the CJS Subcommittee Markup for Appropriations today.

Need the itemized details (tomorrow?) but appears the rec FY26 budget for DOC and relative Science Agencies would remain relatively flat compared to FY24 levels.

Crew Works Ongoing Spacecraft Operations, Robotics, and Combustion Science - NASA Docked spacecraft operations were the main focus at the International Space Station on Thursday with crew departure training, cargo packing, and an orbital reboost also taking place. The Expedition 72 crew also worked on science hardware activating a free-flying robotic assistant and preparing for a fire safety experiment.

This is an artist's concept of the early stages of the young star FU Orionis (FU Ori) outburst, surrounded by a disk of material. A team of astronomers has used the Hubble Space Telescope's ultraviolet capabilities to learn more about the interaction between FU Ori's stellar surface and the accretion disk that has been dumping gas onto the growing star for nearly 90 years. They found that the inner disk, touching the star, is much hotter than expected—16,000 kelvins—nearly three times our Sun's surface temperature. That sizzling temperature is nearly twice as hot as previously believed. NASA-JPL, Caltech

The Hubble data indicates a much hotter impact region than models have previously predicted," said Adolfo Carvalho of Caltech and lead author of the study. "In FU Ori, the temperature is 16,000 kelvins [nearly three times our Sun's surface temperature].
