The first demo flight for the Commercial Orbital Transportation Services (COTS) program could happen no earlier than Wednesday December 8th.
This is the first-ever test flight of a Dragon spacecraft, an entirely new spacecraft designed in the last decade, and only the second ever test flight of the Falcon 9 launch vehicle.  It also marks the first time a commercial company is attempting to re-enter a spacecraft from orbit.

On the December 8th, the launch window opens at 9:03 AM EST / 6:03 AM PST / 15:03 UTC and closes at 12:20 PM EST / 9:20 PST / 18:20 UTC

A US capsule that could soon be hauling cargo and even astronauts to the space station is set to make its first demonstration flight on Wednesday.
The Dragon ship will be launched from Florida on a Falcon 9 rocket, with the aim of entering a circular orbit some 300km above the planet.
The launch window for Wednesday's mission opens at 09:00 EST (14:00 GMT) and runs for three hours and 22 minutes.
