Crew-12 Set for SpaceX Dragon Flight to the ISS

Crew-12—Andrei Fedyaev, Jack Hathaway, Jessica Meir and Sophie Adenot—are slated to launch no earlier than Feb 11 from Cape Canaveral aboard SpaceX's Dragon, propelled by a Falcon 9, to the ISS for about nine months and to join Expeditions 74/75. Adenot and Hathaway will make their first spaceflight; Meir is on her second, and Fedyaev would become the first cosmonaut to fly twice on Dragon. The quartet quarantined Jan 28 at Johnson Space Center and will move to Kennedy Space Center Feb 6; launch windows are Feb 11 with backups Feb 12–13. The εpsilon mission highlights international cooperation and science in orbit.

Stunning New Mars Images Reveal Surprising Details and True Colors

ESA's Mars Express has captured an image of a unique crater on Mars that resembles a butterfly, formed by a low-angle impact that created irregular wings and a central oval body, with evidence suggesting interaction with water or ice during formation. The region also features volcanic mesas and signs of past volcanic activity, providing insights into Mars's geological history.

Scientists Detect First Explosive Burst from Nearby Star

Astronomers have confirmed the first observation of a coronal mass ejection (CME) from a star other than the Sun, using ESA's XMM-Newton and LOFAR telescopes. The CME, originating from a red dwarf star 130 light-years away, was extremely fast and dense, capable of stripping away planetary atmospheres, which has significant implications for the habitability of planets orbiting active stars.

XRISM reveals unexpected speeds in cosmic wind from X-ray binary

The XRISM mission has discovered that the winds from a neutron star system are unexpectedly dense and slower than those from supermassive black holes, challenging current understanding of how such winds form and influence their environments. The findings suggest that differences in accretion disc temperature and size may explain the variations, providing new insights into cosmic feedback mechanisms and galaxy evolution.
