The launch stands as a follow-up to Isaacman's 2021 Inspiration4 mission, in which he and three other private citizens launched on the first-ever civilian-only spaceflight. Inspiration4 helped raise $250 million for St. Jude Children's Research Hospital in Memphis, Tennessee, and Isaacman hopes to build on that momentum...

NASA Space Technology A team of researchers used data from NASA’s Chandra X-ray Observatory, Neil Gehrels Swift Observatory, and ESA’s XMM-Newton to offer a new understanding of how and when a supermassive black hole consumes material.In 2018, the optical All Sky Automated Survey for SuperNovae noticed a system called AT2018fyk, in which a black hole partially disrupted a star.ASAS-SN noticed this system had become much brighter. When scientists observed it with NASA’s NICER (Neutron Star Interior Composition Explorer) and Chandra and XMM-Newton, they found that the brightness came from TDE, which signifies that a black hole partially ingested a star after flying too close to a black hole.The material from the star got hotter and produced X-ray and ultraviolet (UV) light as it approached close to the black hole. These signals then faded, suggesting nothing...
