Live coverage: Soyuz launches on 13th flight from French Guiana

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.

The launch for the second Falcon Heavy rocket from the Kennedy Space Center in Florida has slipped until Wednesday at the earliest. The powerful rocket is due to carry the Arabsat 6A communications satellite into orbit.

An Ariane 5 countdown in French Guiana was aborted Tuesday with the European-made rocket’s main engine already running, postponing the launch of two commercial communications satellites until engineers can resolve the problem.
