And liftoff! The Falcon takes flight. Propelling
the Deep Space Climate Observatory on a
million-mile journey to protect our planet
Earth.
Mike Curie/NASA Launch Commentator: Beautiful
ascent.
Mike Curie/NASA Launch Commentator: One minute,
13 seconds after liftoff, the
Falcon 9 will reach supersonic speed. Fifty
seconds into flight now.
Falcon 9 basking in the glow of the sunset.
Launch Controller: Altitude 6.5 kilometers.
Downrange distance 4.3 kilometers.
Speed 599 meters per second.
Launch Controllers: Recovery has acquisition
of signal.
Mike Curie/NASA Launch Commentator: Standing
by to pass through the maximum
aerodynamic pressure.
Launch Controller: Vehicle is supersonic.
Mike Curie/NASA Launch Commentator: Falcon
9 is supersonic.
Launch Controller: Vehicle has reached maximum
aerodynamic pressure.
Mike Curie/NASA Launch Commentator: Everything
"Go."
Mike Curie/NASA Launch Commentator: Falcon
and DSCOVR passing through
Max-Q.
Mike Curie/NASA Launch Commentator: Two minutes
into the flight of Falcon and
DSCOVR.
Launch Controller: Vehicle remains on a nominal
trajectory.
Altitude 33.9 kilometers. Down range distance
20.9 kilometers.
Speed 1,468 meters per second.
Mike Curie/NASA Launch Commentator: Standing
by for the first-stage engines to
shut down. First-stage cutoff in about 23
seconds.
Launch Controller: Vehicle remains on a nominal
trajectory.
Altitude 57.9 kilometers. Down range distance
50.0 kilometers.
Speed 2,350 meters per second.
Launch Controller: We have MECO1.
Mike Curie/NASA Launch Commentator: And we
have Main Engine Cutoff.
Launch Controller: Separation confirmed.
Mike Curie/NASA Launch Commentator: Second
stage engine ignition . . .
Launch Controller: And we have Stage 2 engine
ignition.
Mike Curie/NASA Launch Commentator: has occurred
on time.
The Falcon 9 Merlin vacuum engine producing
92,000 pounds of thrust,
continuing to carry DSCOVR to its place in
space.
Standing by for the fairing jettison, this
will expose DSCOVR to space for the first
time.
And we see a good fairing jettison.
