Astronaut Wang Yaping became the first Chinese woman to walk in space, authorities said Monday, as her team completed a six-hour stint outside the Tiangong space station as part of its ongoing construction. Tiangong - meaning "heavenly palace" - is the latest achievement in China's drive to become a major space power, after landing a rover on Mars and sending probes to the Moon. Its co

After almost 200 days in space it is time to return to planet Earth for ESA astronaut Thomas Pesquet, JAXA astronaut Aki Hoshide and NASA astronauts Shane Kimbrough and Megan McArthur.

Timelapse video made during ESA astronaut Thomas Pesquet’s second mission to the International Space Station, “Alpha”. The camera is setup to take pictures at intervals of two a second, and the pictures are then edited into this video that plays at 25 pictures a second. The camera was setup in the Japanese Kibo module and shows the solar arrays moving as they prepare to track the Sun when the Space Station flies back into sunlight. The new IROSA solar array upgrades can be seen that Thomas and NASA astronaut Shane Kimbrough installed over the course of three

The Space Development Agency in early 2022 will seek bids for the ground segment portion of its low-Earth orbit constellation.

NASA has delayed the undocking of a Crew Dragon spacecraft from the International Space Station by a day because of high winds at splashdown locations in the Gulf of Mexico, a move that won’t affect the launch of the next crew to the station.

A group of astronomers, led by scientists from the Max Planck Institute for Astronomy, propose and have tested a mechanism that explains most of the properties observed in dispersing planet-forming disks around newborn stars for the first time. The key ingredients to this new physical concept are X-ray emissions from the central star and a calm inner disk, well shielded from the incident radiati

NASA plans to launch a spacecraft as early as Nov. 23 and crash it into an asteroid next year so scientists can try to understand how to redirect dangerous space objects away from potential catastrophic Earth collisions. The mission is NASA's first flight demonstration for planetary defense, space agency officials said. The Double Asteroid Redirection Test, or DART, is scheduled for
