Richard "Mars" Grimstone is part of the United Space And Discovery (USAD) program's Mission Control. It's his job to be a contact between their men in space and those in charge of the program on Earth. Mars monitors the astronauts' life signals, locations and advises them on possible next steps from his office chair. Mars has a brief military background, though it's not talked about. Mars is often assigned to the "Lunar Red" team, who was the first team to discover aliens. He's tired.
