Unberthing is currently schedule for 1:05 AM Phoenix time (0805 UTC).
Dragon is currently equilibrating the pressure prior to departure.
Image below shows the location of Dragon attached to the ISS. The location is the Pressurized Mating Adapter (PMA) attached to the Harmony node.
Dragon is attached to Canadarm and is slowly releasing the bolts and latches.
The Canadarm (Space Station Remote Manipulator System – SSRMS) is waiting for all the latches to be released prior to moving the Dragon to its release point.
The breaks are on the SSRMS, preventing the arm from moving and damaging the docking and latching mechanisms.
At 0755 UTC, work on the third set of bolts on the Common Berthing Mechanism (CBM) is in progress. We are about 10 minutes from release.
At 0802 UTC, the fourth and final set of bolts is being released.
And Dragon is released (demated) from the ISS at 0807 UTC.
Time on Station: 5 days, 16 hours, 5 minutes.
Re-entry coverage begins on NASA TV at 7:15 Am Phoenix time (1415 UTC).
