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.
The screen with the launcher displays a message in the upper corner that appears to say: "Tin Can Shooter" and "UPS!! seventh and gave up on the most of the way."
