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

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.

Orbital ATK’s Minotaur-C rocket, formerly known as the Taurus, has launched for the first time in six years from Vandenberg Air Force Base in California. The solid-fueled launcher lifted off with 10 commercial Earth-imaging satellites at 2:37 p.m. PDT (5:37 p.m. EDT; 2137 GMT) Monday.

A United Launch Alliance Atlas 5 rocket lifted off from Cape Canaveral’s Complex 41 launch pad Sunday night with the European Space Agency’s Solar Orbiter mission, a project developed in partnership with NASA. Launch occurred right on time at the opening of a two-hour window at 11:03 p.m. EST Sunday (0403 GMT Monday).
