Four space station fliers have been told to cut their mission short and return to Earth ahead of schedule because of an apparently serious medical issue affecting an unidentified crew member, NASA announced Thursday.
NASA has decided to bring the four astronauts of SpaceX's Crew-11 mission home from the International Space Station early due to a medical issue experienced by a crewmember in orbit.
"Nothing in my professional training as an X-ray astronomer had prepared me for something like this."
Mars has a curious past. Rovers have shown unequivocal evidence that liquid water existed on its surface, for probably at least 100 years. But climate models haven’t come up with how exactly that happened with what we currently understand about what the Martian climate was like back then. A new paper, published in the journal AGU Advances by Eleanor Moreland, a graduate student at Rice University, and her co-authors, has a potential explanation for what might have happened - liquid lakes on the Red Planet would have hid under small, seasonal ice sheets similar to the way they do in Antarctica on Earth.

Josef Aschbacher, Director General of the European Space Agency, briefed journalists on the main milestones for 2026, such as the launch of Smile, a mission that will give humankind its first complete look at how Earth reacts to streams of particles and bursts of radiation from the Sun. Later in 2026 should also see the arrival of BepiColombo at Mercury after its eight-year trip, where it will gather data to answer many perplexing questions about the least-explored planet of the inner Solar System. Many more exciting missions are expected, with ESA astronaut Sophie Adenot launching for the International Space Station, and various Earth Observation and Navigation launches from Europe’s Spaceport in French Guiana.
"This was many times more energetic than any similar event and more than any known explosion powered by the collapse of a star."
