Live coverage: 400th Proton rocket takes off with Russian satellite

An Ariane 5 rocket took off on a rare morning launch Thursday with four Galileo navigation satellites, the heavy-lifter’s first flight in support of the European positioning and timing fleet. Liftoff from French Guiana occurred at 1306 GMT (8:06 a.m. EST).

Russia’s Progress MS-06 supply ship launched Wednesday aboard a Soyuz rocket from the Baikonur Cosmodrome in Kazakhstan, on the way to deliver food, fuel, spare parts, oxygen and water to the International Space Station’s crew.

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.
