That would be a 9 minute deorbit burn, not the departure burn.

Some discussion of visibility of reentry trail from the station, probably not visible because will be daylioght. Dragon will be 377 miles (IIRC) ahead of the station when it "really starts to heat up".

Discussion of importance of Dragon and COTS in general to NASA. Some suporting video. Don Pettit likens COTS to wagon trains supplying Government forts out west.

Now back live.

Acaba will have the lead SSRMS role for unberthing, Pettit will have the lead for release.

First set of bolts (4 of 16) undone and working on the second set of four as the station moves into sunrise

Everyone seems quite relaxed in the SpaceX control room

shaula1247 · « **Reply #36 on:** 05/31/2012 07:41 am »

Second set of bolts complete, one has an unusual torque response but this has been seen before with this bolt and there is no concern.

A period of ratty com is holding up progress, need to wait another 3 minutes or so for solid comms.

shaula1247 · « **Reply #38 on:** 05/31/2012 07:52 am »

Work on third set of bolts now beginning after wait for good comms to enable proper monitoring.
