1997-073A
STS-87 pioneered a heads-up roll at T+5min, communicating with the TDRS network instead of the old Bermuda station.
Deploy of the Spartan solar observatory was delayed a day when SOHO went into safemode. Then on Nov 21, Chalwa released Spartan using the RMS arm. But Spartan failed to make its orientation `pirouette' and an attempt was made to regrapple the satellite. Capture was not successful and the arm tipped the satellite over, causing it to tumble. For about an orbit the astronauts tried to manuever to match Spartan's rate, but then Mission Control ordered them to back off to preserve fuel for an attempt during the already planned spacewalk a few days later. In April 1998 the internal review was made public, blaming Chalwa for failing to send the command to switch on the satellite before deployment, and for closing the RMS grapple too quickly, messing up the attempt to recapure it.
In the Nov 25 spacewalk, astronauts Scott and Doi placed themselves on the SPSS as Columbia flew up to match orientation and rates with Spartan. After several hours flying close to the craft, they grabbed it out of space and held it. It was finally lowered into the cradle using the RMS.
The second EVA on Dec 3 was added to the schedule to allow more tests of the crane. It also featured the free flight of AERCam, which reached a maximum range of 12m from Columbia.
