A little while ago, SpaceX’s Crew Dragon Endeavour spacecraft completed its Crew-11, or SpaceX Crew-11, mission for NASA with a successful splashdown. Aboard were astronauts Zena Cardman, Michael Fincke, and Kimiya Yui, and cosmonaut Oleg Platonov, who had arrived at the International Space Station on August 2, 2025, as part of Expedition 73/74. The Crew-11 members ended SpaceX’s 11th regular crewed mission in the Pacific Ocean, off the coast of California. The Crew Dragon had left the Station approximately 11 hours earlier.

The Crew-11 mission ended a few weeks early in what was described as a medical evacuation due to a medical condition affecting one of the crew members. For privacy reasons, no details were released, starting from the identity of the person who’s suffering the health issue.

A few hours ago, a Falcon 9 rocket launched from Vandenberg Air Force Base on the Twilight rideshare mission, carrying a total of 40 satellites in various phases. About two hours and twenty minutes after launch, the final group of satellites was deployed by SpaceX’s system. Among them were NASA’s Pandora Space Telescope and the BlackCAT and SPARCS nanosatellites, both 30x20x10-centimeter CubeSat-class satellites, part of NASA’s CubeSat Launch Initiative. These satellites will conduct their astronomical observations from low-Earth orbit.

An article published in “The Astrophysical Journal Letters” reports the discovery of what was dubbed Cloud-9, which can be described as a failed galaxy. A team of astronomers used observations with the FAST radio telescope to identify what appears to be a new type of astronomical object, and follow-up observations with the Hubble Space Telescope, the Green Bank Telescope (GBT), and the Very Large Array (VLA) to confirm the existence of the first object of its kind that was identified with reasonable certainty.

Technically defined as a reionization-limited H i cloud (RELHIC), Cloud-9 is a starless gas cloud that is supposed to be composed of dark matter filled with hydrostatic gas in thermal equilibrium with the cosmic ultraviolet background. Cloud-9 will help test cosmological models regarding dark matter.
