Live coverage: Atlas 5 rocket lifts off from Cape Canaveral

SpaceX’s Falcon Heavy rocket stood atop historic launch pad 39A on Monday, one day before 27 kerosene-fueled rocket engines will dispatch the towering rocket into space with nearly 5 million pounds of thrust.

Astronauts Butch Wilmore and Suni Williams arrived at the Cape in T-38 jets, the first such arrival since the space shuttle era. The mission is aiming to launch on Monday, May 6, at 10:34 p.m. EDT (0234 UTC).

NASA has announced that Astrobotic, Intuitive Machines and OrbitBeyond won contracts to deliver science instruments and technology demonstration payloads to the moon’s surface in the first of a series of robotic missions preceding a human return to the moon.
