He is famous for his work as an aerospace engineer, who designed an orbital rendezvous
technique critical to future planetary landings.
In the 1980s, Aldrin adapted his expertise in orbital rendezvous
to conceptualize the "Aldrin Mars Cycler," a spacecraft transportation system perpetually cycling between Earth and Mars that would make it possible to ferry astronauts back and forth to the Red Planet.
He was also a member of the Gemini 7 crew, which performed the first ever orbital rendezvous
linking with Gemini 6 in 1965.
automated intelligence and computer systems will be an integral part of the missions.
