The sign by the exhibit. It reads:
The December 1965 Gemini VII
mission was the first flight to use the new G5C lightweight flight suit. The
plan called for one of the crewmen to remain suited—a very
uncomfortable proposition—while the other was allowed to remove his
suit. NASA let both crewmen remove their suits except for the rendezvous and
reentry phases of the flight. For obvious reasons, the G5C space suit became
known as the "Grasshopper" suit.
Gemini VII was the first mission where both crewmen slept at the same time.
Each astronaut took a book along with him to read before going to sleep.
Appropriately, Borman chose Mark Twain's
"Roughing It." Lovell chose "Drums along the
Mohawk" by James Fenimore Cooper.
