Photos: Tuesday’s Atlas 5 rollout

A troublesome liquid oxygen valve on the Space Launch System’s first flight-rated core stage will keep NASA from performing a second test-firing of the rocket’s four main engines this week.

The latest launch date was announced late Wednesday evening, following a Tuesday night notice that May 25 was off the table. Liftoff of the Atlas 5 rocket on June 1 is set for 12:25 p.m. EDT (1625 UTC).

The world’s highest capacity broadband satellite, a craft that will connect rural America to high-speed Internet service, successfully rocketed into space today aboard a United Launch Alliance Atlas 5 booster.
