Live coverage: Ariane 5 blasts off with two Intelsat satellites

United Launch Alliance kicked off its 2018 launch campaign with a Delta 4 rocket flight at 2:11 p.m. PST (5:11 p.m. EST; 2211 GMT) Friday from Vandenberg Air Force Base in California. Gusty winds forced officials to call off a launch attempt Wednesday, and technical problems halted a countdown Thursday multiple times. The Delta 4 launched with a top secret spy satellite for the National Reconnaissance Office.

Eight of Iridium’s first ten upgraded communications satellites launched in January started providing voice and data relay service ahead of schedule, and SpaceX says it can launch up to 40 more Iridium spacecraft by the end of the year, Iridium officials reported Thursday.

A Falcon 9 rocket took off for its fourth flight of the year Friday with a middle-of-the-night mission for SKY Perfect JSAT, a Tokyo-based satellite operator. The JCSAT 14 communications satellite launched from Cape Canaveral at 1:21 a.m. EDT (0521 GMT), and the rocket’s first stage booster made a successful landing at sea a few minutes later.
