Wrapping up a six-month mission in orbit, three Chinese astronauts departed the Tiangong space station Saturday and landed in the remote Gobi Desert of northwestern China at 6:33 p.m. EDT (2233 UTC).

Rocket Lab announced Saturday it will hold off launching an Electron rocket on an orbital test flight until early 2018 as officials face the end of a 10-day pre-approved launch window, after a series of scrubs to ensure the booster is ready for liftoff and wait for ideal weather conditions.

NASA’s robotic InSight spacecraft, carrying a pair of European-built science instruments, successfully landed Monday on a broad, flat equatorial Martian plain named Elysium Planitia. Touchdown was confirmed at 2:54 p.m. EST (1954 GMT) to begin a science mission focused on studying the deep interior of Mars.
