The launch was ultimately scheduled for December 8, 2010, with launch windows available from 9:00 to 9:06 a.m., 10:38 to 10:43 a.m., and 12:16 to 12:24 p.m. EST based on the availability of the NASA Tracking and Data Relay Satellite (TDRS) network used to track and communicate with the spacecraft. The first attempt was originally scheduled for the middle of the first launch window, at 9:03, but was moved to the end of the window at 9:06 a.m. EST. This attempt was aborted with 2:48 left in the countdown clock because of false telemetry data.

The launch was re-targeted for 10:43 a.m. EST, and was successful.[7] First stage engines cut off at T+2:56, nose cone separated at T+3:47, second stage engines cut off at T+8:56, all as planned. The Dragon vehicle separated at T+9:30 and achieved a near circular orbit, with a perigee of 288 kilometres (179 mi) and an apogee of 301 kilometres (187 mi) and an inclination of
