There has been speculation that an
EVA was conducted during this mission.
[5] Interviews with members of the crew several years after the flight confirmed there had been a problem with the satellite upon release, whereupon a rendezvous with the satellite was effected and repairs performed.
[6][7] These unspecified repairs could have necessitated a spacewalk, likely performed by Ross and Shepherd. As a classified DoD mission, details or confirmation of such an EVA remain unreleased.
