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.

A Russian-built Soyuz rocket moved to its launch pad on the northeastern coast of South America on Tuesday ahead of a Friday night flight with a Spanish-owned communications satellite to relay video and broadband signals between the Americas and Europe.

NASA’s live television coverage of the first human spaceflight to take off from the Kennedy Space Center in nearly nine years will include features familiar to launch viewers, and new camera views to document the historic flight of astronauts Doug Hurley and Bob Behnken to the International Space Station.
