Here is a CRS-3 launch and ascent event list. Please note that all timings and values are approximate, as I have based them on a mix of CRS-2 profile telemetry and CRS-3 mission notes.

T-00:00:00 - Falcon 9 lift-off. Stage 1's nine Merlin engines produce 1.3M pounds of thrust.

T+00:00:07 - Falcon 9 clears the launch tower.

T+00:01:00 - Altitude: 6km, Velocity: 241m/s, Downrange distance: 1km

T+00:01:10 - Falcon 9 achieves supersonic speed.

T+00:01:23 - Falcon 9 achieves maximum dynamic pressure (Max Q).

T+00:02:00 - Altitude: 30km, Velocity: 1km/s, Downrange distance: 23km

T+00:02:30 - Altitude: 51km, Velocity: 1.8km/s, Downrange distance: 59km

T+00:02:41 - MECO (Main Engine Cut-Off) Altitude: 80km, Velocity: Mach 10

T+00:02:44 - Stage 1 separates from Stage 2.

T+00:02:45 - Stage 2's single Merlin engine ignites.

T+00:03:25 - Dragon's nose cone is jettisoned.

T+00:04:21 - Altitude: 148km, Velocity: 3.2km/s, Downrange distance: 346km

T+00:05:22 - Altitude: 182km, Velocity: 4km/s, Downrange distance: 541km

T+00:06:24 - Altitude: 200km, Velocity: 4.6km/s, Downrange distance: 767km

T+00:07:31 - Altitude: 210km, Velocity: 5.6km/s, Downrange distance: 1,080km

T+00:09:40 - SECO (Second-stage Engine Cut-Off)

T+00:10:15 - Stage 2 separates from Dragon.

Elon has just confirmed [1] that they will be attempting to recover the first stage. This is the first flight with the landing leg module attached to the first stage. The landing legs will be deployed over sea for a soft landing in preparation for a land-based recovery.

This will be a historic moment if the recovery succeeds, ushering in a new era of space travel due to the massively reduced operating costs of recoverable engines.
