Russia launched an unmanned Soyuz spacecraft to the International Space Station on Thursday to replace one that leaked coolant after it was struck by a meteoroid last year, stranding two cosmonauts and a NASA astronaut in space. The Soyuz MS-23 spacecraft was launched with 948 pounds of supplies for the astronauts from the Baikonur Cosmodrome in Kazakhstan at 7:24 p.m. EST, which was br

A billionaire-backed series of private astronaut missions is now planning its first launch this summer that will include the first spacewalk on a commercial spaceflight.

ESA’s Hera asteroid mission for planetary defence is about to gain its sight. Two complete and fully tested Asteroid Framing Cameras have reached OHB in Germany for integration aboard Hera’s payload module. This instrument will provide the very first star-like view of Hera’s target for the mission to steer towards the Dimorphos asteroid, which last year had its orbit altered by an impact with NASA’s DART mission.

Over the last few months, ESA’s Earth Explorer Biomass satellite has been going through a punishing series of tests to make sure that it will survive the unavoidable blasts of noise and shuddering during liftoff. Engineers have now also tested that it will unfold its solar wing in the correct sequence. Coming through all of this with flying colours, Biomass is a few steps closer to its mission in orbit: to deliver completely new information on our precious forests and the carbon they store.
