1996-018A
The third Mir docking mission, STS-76 (S/MM-3), was intended to inaugurate a permanent US presence in space. The crew included Mission Specialist 4 Shannon Lucid, who transferred to the Mir station, becoming Kosmonavt-issledovatel' on the Mir EO-21 crew. Lucid was the first woman to make five space flights. On this mission, the Spacehab module was carried in the cargo bay as a storage room for the supplies being brought to Mir. Launch on 1996 Mar 22 was marred by a leak in APU No. 3, and for a while it looked as if the mission might be curtailed. Rendezvous went smoothly and Atlantis completed the first docking with the 316GK module which it had left attached to Mir on the previous flight.
The crew transferred supplies to Mir from the Spacehab module, including a large number of water containers. During the docked phase, EV astronauts Linda Godwin and Rich Clifford emerged from the airlock in the Tunnel Adapter, and transferred four attache-case-sized MEEP experiment trays from the rear Shuttle cargo bay to the 316GK module. They were attached with clamps to handrails on the exterior of the module and opened up to expose the samples they carried to the space environment.
After undocking, the landing date was brought forward a day in the hope of beating approaching bad weather at the Cape, but to no avail. A waveoff at KSC on Mar 30 and Mar 31 resulted in the first Edwards landing in over a year.
The orbiter was attached to Shuttle Carrier Aircraft 905 for the return trip to Florida, but the SCA's flight was aborted when a fire broke out in one of the Boeing 747's engines. The 747 had to make an emergency landing with a weight well in excess of normal limits, former astronaut Gordon Fullerton flying the plane. The engine was replaced and the return trip resumed on Apr 11 without incident.
