This Space Shuttle Atlantis thermal blanket is a hand-cut piece of insulation that flew inside Atlantis. NASA paperwork ties it to STS-86, the shuttle's 1997 mission to Mir.
The Thermal Control System helped the ship withstand the extreme heat of re-entry. Crews applied the blanket inside the shuttle to protect internal components. Soft goods like this gave lightweight insulation to delicate items.
This shuttle insulation blanket is layered. It holds aluminized Kapton foil and fibrous bulk material.
Atlantis (OV-104) was the fourth of five orbiters and the last one flown. The STS-86 mission was the seventh Shuttle-Mir docking. It launched on September 25, 1997 (September 26 UTC) and docked with Mir on September 27.
Atlantis helped send probes to Venus and Jupiter and added modules to the International Space Station. See more flown pieces in our Authentic Historical Artifacts.
Space Shuttle memorabilia like this needs care. Kapton is light and slightly brittle, so fragments can fly away or break if you open the jar. The jar bottom is marked so each shuttle insulation blanket specimen can be told apart.
STS-86 included the first joint U.S.-Russian spacewalk during a shuttle flight. Few pieces of space shuttle memorabilia come from inside the ship. Your Space Shuttle Atlantis thermal blanket comes from the STS-86 mission.
