SpaceX Crew Dragon capsule, 4 astronauts bound for space station

With improving conditions expected on and off shore, SpaceX readied a Falcon 9 rocket for a pre-dawn launch Friday to boost a Crew Dragon capsule carrying four astronauts into orbit for a one-day trip to the International Space Station.

Liftoff from pad 39A at the Kennedy Space Center is targeted for 5:49 a.m. EDT Friday, setting up an automated rendezvous and docking at the space station early Saturday.  The SpaceX "Crew-2" flight will mark only the third launch of NASA astronauts from U.S. soil since the space shuttle's retirement 10 years ago. It is the second operational flight under NASA's Commercial Crew Program and the first to use a previously-flown first stage booster and a refurbished Crew Dragon capsule making its second flight.
