SpaceX
successfully launched its Crew Dragon spacecraft on a Falcon 9 rocket from
historic Launch Complex 39A at NASA’s Kennedy Space Center in Florida at 2:49
am EST this morning. Main engine cutoff and stage separation were
confirmed by SpaceX at 2:52 am EST.

First
stage successfully landed on the drone ship platform Of Course I Still Love You
at 3:00 am EST. The Crew Dragon is scheduled to dock with the International
Space Station early Sunday morning. It will spend about five days docked to the
station before returning to Earth and splashing down in the Atlantic.
The
launch marks the first time a private American rocket and spacecraft built for
human passengers has ever launched to travel to the space station. An upcoming
crewed mission, Demonstration Mission 2, is scheduled
for July.

There
are no human astronauts on board. It does carry “Ripley,” a SpaceX dummy that
will collect valuable information — using sensors all over its body —
about what the experience will be like for human astronauts. A previous version
of SpaceX’s Dragon capsule built solely for cargo became the first commercial
spacecraft to deliver cargo to the ISS and safely return cargo back
down to Earth back in 2012.
Since
then, SpaceX has flown 16 successful cargo
missions to the space station on behalf of NASA using the Dragon
spacecraft.
Ready
To Dock
If
all goes well, the Crew Dragon will rendezvous with the International Space
Station at around 6:00 am EST Sunday morning to dock autonomously. But the
docking procedure is quite different this time when compared to previous Dragon
missions:
“Dragon
was basically hovering under the ISS,” said Hans Koenigsmann, vice
president of mission assurance at SpaceX during a pre-launch
briefing on Thursday. “You can see how it moves back and forth and
then the [Canadarm] takes it to a berthing bay.”
In
contrast, the Crew Dragon’s docking system is active, he said:
“It will plant itself in front of the station and use a docking port on its own, no docking arm required.”
