Apollo Intravehicular Activity (IVA) spacesuit, 1968.

This spacesuit was worn by William Anders during the first manned flight round the Moon, the Apollo 8 mision at Christmas 1968. During the Moon landing misions, an IVA suit was worn by the Command Module pilot, who did not leave the spacecraft. It could not be worn outside, as it did not have a Thermal Micrometeoroid Garment, or an extravehicular visor asembly. Unlike the suits worn on the Moon, the IVA suit does not have a Portable Life Support System backpack. Oxygen is supplied from the spacecraft itself.
