STS-81 (Atlantis)

 1997-001A

---

STS-81 was the fourth Mir docking mission. It carried supplies for Mir in the Spacehab Double Module, and carried up Jerry Linenger to replace John Blaha.

After five days of docked operations, Atlantis made two revs around Mir and then departed. Landing at Kennedy Space Center came two days later.
