1997-055A
Like earlier Mir flights, STS-86 was flown with the internal airlock present, and the shell of the external airlock in the payload bay supporting the Orbiter Docking System. The internal airlock would be removed during the next maintenance period.
Lawrence was replaced by Wolf on Jul 31 since she was too small (1.60m) to operate the Orlan EVA suit, and NASA wanted the US astronaut available to support Spektr repair EVAs. A GAS payload was removed from the payload bay to save mass in favor of extra replacement parts for Mir. G-036, for El Paso Community College, was on a GABA in bay 13S together with the SEEDS can.
The EVA suits for STS-86 featured the first operational use of SAFER, using the first two production flight units.
The Spektr Solar Array Cap (SSAC), loaded at the last minute, was installed in the airlock until needed for the EVA. The EVA would retrieve the MEEP packages from the SO, and would test the SAFER hand controller. DTO 671 involved tests of the common PFR, and the rigidized MUT (Multi Use Tether) with its end effector and tool carrier. EV1 was Parazynski with PLSS 5, EV2 was Vladimir Titov with PLSS 4 in the first use of a US EVA suit by a Russian.
