Live coverage: Soyuz crew capsule departs station, lands in Kazakhstan

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.

A commercial Dragon cargo capsule is heading back to Earth Tuesday to conclude a 31-day stay at the International Space Station. The SpaceX-owned spacecraft was released from the station’s Canadian-built robotic arm at 10:59 a.m. EDT (1459 GMT), and the Dragon supply ship splashed down in the Pacific Ocean with nearly 3,400 pounds of cargo at 4:21 p.m. EDT (2021 GMT).

A Soyuz-2.1b booster loaded with 34 satellites for OneWeb’s global Internet network rolled out of its assembly building Monday at the Baikonur Cosmodrome in Kazakhstan and rode a rail car to its launch pad for final preflight checks before liftoff Thursday.
