Astronauts 3D-print 1st metal part while on ISS

NeRD

ESA scientists have successfully demonstrated 3D printing of a metal part in space for the first time.  3D printing in space poses challenges, as many methods rely on gravity to position materials during the printing process. This is because when creating metal structures, molten metal is often used as part of the filament, or printable medium. In space, its behavior can be unpredictable, which can result in poor-quality objects, as the filament might shift or be placed incorrectly due to the lack of gravitational forces. Scientists therefore had to adapt…

This Week In Space podcast: Episode 128 —Starliner is Back! What Now?

NeRD

Starliner is Back! What Now? – Can Boeing Compete with SpaceX’s Dragons? – YouTube Watch On On Episode 128 of This Week In Space, Rod Pyle and Tariq Malik talk about what’s going on with Boeing’s Starliner CST-100 spacecraft. Starliner is back and, by all accounts, could have returned with its crew had it been necessary. However, with NASA’s “safety forward” approach prevailing, the spacecraft landed uncrewed on September 6, three months after it docked with the International Space Station. Now, the work begins to try to solve the problems-…
