Lunar Gate

Lunar Gate (ルナゲート, Runagēto) is a location in Final Fantasy VIII. It is an airport-like facility used by Esthar to shuttle people to the Lunar Base.

To launch someone (or presumably something) into space, s/he is placed in a capsule. They then undergo a process called "cold sleep", rendering them unconscious for the trip, and are shot out of a cannon-like apparatus into space. They are "thawed" upon arrival at the Lunar Base. The Queen of Cards can also be found here.
