After Wednesday's scrub due to weather, NASA and SpaceX have
targeted Saturday, May 30, for the next launch attempt for the Demo-2 mission,
the first launch of astronauts on an American rocket from American soil since
the last space shuttle mission in 2011.
“I think our teams worked together in a really impressive
way, making good decisions all along,” NASA Administrator Jim Bridenstine said
Launch of the mission, dubbed Launch America, is scheduled
for 2:22 p.m. CDT on Saturday. NASA TV coverage begins bright and early at 10
a.m. Members of the public can participate in the mission through NASA’s virtual guest
Administrator Jim Bridenstine watches as NASA astronauts Douglas Hurley and
Robert Behnken return to the Neil A. Armstrong Operations and Checkout Building
from Launch Complex 39A after the launch was scrubbed due to weather on May 27,
2020, at NASA’s Kennedy Space Center in Florida.
