July 26, 1971: 45th anniversary of Apollo 15

Ground crews at Vandenberg Air Force Base in California raised a United Launch Alliance Atlas 5 rocket on its launch pad earlier this month in preparation for liftoff May 5 with NASA’s InSight lander heading to Mars.

The United Launch Alliance Atlas 5 rocket, standing 189 feet tall and and weighing 840,000 pounds, unleashes 1.2 million pounds of thrust from its main engine and one side-mounted booster at 7:05 p.m. EDT (2305 GMT) today to launch NASA’s OSIRIS-REx mission to Asteroid Bennu.

Mission managers will be closely monitoring the weather for the first launch of astronauts aboard SpaceX’s Crew Dragon spacecraft, not just around the Kennedy Space Center, but along a corridor stretching thousands of miles across the Atlantic Ocean in case the crew capsule has to escape from its Falcon 9 rocket during the climb into orbit.
