Live coverage: SpaceX Falcon Heavy launches NASA’s Psyche on mission to a metal asteroid

The Trump administration is requesting $25.2 billion for NASA in fiscal 2021, a 12 percent increase that includes $3.3 billion to kickstart development of a human-rated lander for the Artemis moon program. Nearly half of the budget request, $12.3 billion, is devoted to new and ongoing projects focused on the return to the moon and eventual flights to Mars.

The mission will the fifth flight to space for Peggy Whitson, the American with the most spaceflight experience in history. Liftoff on Wednesday, June 25 is set for 2:31 a.m. EDT (0631 UTC) from Launch Complex 39A.

SpaceX called off a scheduled launch of a Falcon 9 rocket about a half-hour before liftoff from Cape Canaveral Monday due to strong upper level winds, and officials aim to try again to send 60 Starlink Internet satellites into orbit Wednesday after bypassing a planned launch attempt Tuesday due to poor weather in the offshore booster recovery area.
