A few days ago, it was reported that NASA’s InSight lander had found evidence for an oddly pulsating magnetic field, a more magnetic crust than expected and – maybe – the existence of a […]

'Engines in Post-Shutdown Standby': Remembering the Fall and Rise of STS-68, 25 Years On (Part 1)

Mars is usually thought of as pretty much a dead world, geologically-speaking. But NASA’s InSight lander is finding that may not be exactly true. Some early results from InSight’s investigations of the planet’s interior have shown evidence for an oddly pulsating […]

NASA's Jessica Meir, Crewmates Launch to Space Station on Soyuz MS-15

The Soyuz MS-15 spacecraft is launched with Expedition 61 crewmembers Jessica Meir of NASA and Oleg Skripochka of Roscosmos, and spaceflight participant Hazzaa Ali Almansoori of the United Arab Emirates on Wednesday, Sept. 25, 2019 from the Baikonur Cosmodrome in Kazakhstan.
