A little while ago, ispace’s Hakuto-R2 Resilience and Firefly Aerospace’s Blue Ghost Moon landers blasted off atop a Falcon 9 rocket from Cape Canaveral. After about 1 hour and 5 minutes, Blue Ghost successfully separated from the rocket’s upper stage, and about 27 minutes later, Resilience separated as well. The two landers will travel on very different routes to attempt to land on the Moon a few months apart. This is ispace’s second mission, after the first failed on April 25, 2023.

A few hours ago, SpaceX’s Dragon spacecraft ended its CRS-31 (Cargo Resupply Service 31) mission for NASA splashing down smoothly off the Florida Coast. The Dragon left the International Space Station about 24 hours earlier. For SpaceX, this was the 11th mission of the 2nd contract with NASA to transport supplies to the Station with the new version of the Dragon cargo spacecraft.

Shortly after the splashdown, SpaceX’s “MV Megan” recovery ship went to retrieve the Dragon to transport it to the coast. The cargo brought back to Earth will be delivered to NASA within a few hours. The Dragon spacecraft reached the International Space Station on November 5, 2024.

A little while ago, SpaceX’s Crew Dragon Endeavour spacecraft concluded its Crew-8, or SpaceX Crew-8, mission for NASA by landing without problems. On board were astronauts Matthew Dominick, Mike Barratt, and Jeanette Epps and cosmonaut Alexander Grebenkin, who had reached the International Space Station on March 5, 2024, and were part of Expedition 70/71/72. The four of them finished the 8th regular crewed mission of SpaceX in the Atlantic Ocean, off the coast of Florida. The Crew Dragon departed the Station about 34 hours earlier.

Shortly after the splashdown, SpaceX’s “MV Megan” ship went to recover the Endeavour and its crew to transport them to the coast. The astronauts also received their first medical checkup aboard the ship.

An article published in “The Astrophysical Journal Letters” reports the results of a study on the region of very hot plasma that surrounds a black hole called the corona. A group of researchers used detections conducted with the IXPE space telescope to obtain precise information on the corona of 12 black holes ranging from stellar-mass ones to supermassive black holes. For the first time, it was possible to observe the geometry of the corona of black holes and its relationship with the accretion disk that surrounds them. The geometry seems very similar regardless of the size of the black holes but this is still a tentative result.
