How much dV does the Dragon have? Is this extended station-keeping accounted for? You'd assume so...

There is no backwards as such. Remember, Shuttle used to do that too, usually for thermal conditioning, comms and such...

Going to send Dragon to 30 meters, going to continue monitor thermal data

Will take about 30 minutes

They had 36 kg of extra fuel after the far-field phasing, which means about 20 m/s of delta-v. This equates to 300 seconds of firing one of the 400 N Dracos.

For those just joining, I am updating this article as we go:
http://www.nasaspaceflight.com/2012/05/spacexs-dragon-historic-attempt-berth-with-iss/

So you can catch up, as much as I'd still say it'd be best to spend 10 mins going through the 17 pages so far, as that's far more extensive than the article (obviously).

New capture time estimate coming. Preference for a daylight pass for capture.
