Launch occurred at 03:44 EDT (07:44 UTC) on 22 May 2012.
This was the first time a Falcon 9 was launched at night.
After lift-off, main engine shut-off occurred at approximately the 180-second mark, and the first stage began to be separated.
Following stage separation, the second stage ignited.
The Dragon's nose cone was then jettisoned.
And at about nine minutes into the flight, the second-stage engine shut-off occurred and separated from the Dragon spacecraft.
The Dragon spacecraft successfully deployed its solar arrays at about 13 minutes into the flight.

The initial COTS 2 tests began during this flight segment, when Dragon performed a test of its Absolute GPS (AGPS) system, using global positioning system satellites to determine its location.
Next, Dragon opened its bay door which housed its grapple fixture and relative navigation sensors, a thermal imager and the LIDAR based DragonEye.
After a checkout of these sensors was completed, Dragon demonstrated its ability to abort during an approach, first with a continuous firing of its Draco engines and then with a pulsed firing.
A free drift demonstration then began, allowing the spacecraft to float freely without using its thrusters which would normally correct its orbital path.
