Subject: MCC-M Response

The above is a report I have drafted on the MCC-M response to the power loss incident which delayed the Mir EVA. It starts with what I think was a recoverable error (unplugging a key attitude sensor), but inaction by the ground allows the situation to deteriorate into a major problem. It is not completely clear from the information available, but it appears the ground may have even aggravated the situation with an incorrect quaternion uplink.

A classic example of the ground having their heads "up and locked"...

General Stafford gave a general introduction and thanked members for attending. He stressed the importance of the upcoming safety and operational readiness assessment for STS-86. General Stafford explained that he was creating a Task Force Red Team, led by General Ralph Jacobson, to lead the Task Force STS-86 assessment effort to gain efficiencies due to the time constraints under which the Task Force was working.

Frank Culbertson briefed the Task Force on the Progress-Mir Mishap that occurred on June 25, 1997. He reported that during the attempted Mir docking of Progress 223 that led to the collision of the two vehicles and the depressurization of the Spektr module, the crew attempted to complete a manual docking using the TORU docking system without range or range rate. NASA had not historically participated in the test plans for these kinds of maneuvers. Ground controllers at Moscow Mission Control reported that they had good control over the Progress vehicle until they turned control over to the crew. It is not clear how the weight of the vehicle might have affected the performance of the Progress or TORU, but it was clear that the closure rates were higher than nominal.
