Live coverage: Ariane 5 blasts off with two Intelsat satellites

India’s GSLV Mk.3 rocket took off Monday on its first full-scale orbital test flight, delivering the GSAT 19 communications satellite to an on-target orbit after successfully demonstrating new solid rocket boosters, a twin-engine core stage and an upgraded cryogenic upper stage engine.

United Launch Alliance’s Delta 4-Heavy rocket lifted off at 11:10 a.m. PST (2:10 p.m. EST; 1910 GMT) Saturday from Vandenberg Air Force Base, California, after a month-long delay to troubleshoot a hydrogen leak in one of its boosters. The heavy-lifter was on a mission to send a U.S. government spy satellite into orbit.

Ground crews returned to work Monday at the Guiana Space Center, a European-run spaceport on the northeastern shore of South America, after protests and a general strike across French Guiana interrupted launch operations for five weeks.
