Buzz Aldrin is an Astronaut for NASA and part of the Apollo 11 program. He is the third man on the moon, following Alexei Leonov and Neil Armstrong respectively. While Eagle had a rough landing, Aldrin and Armstrong safely landed but lost transmission with Michael Collins and mission control in Houston for over 4 hours. Eventually, they manage to re-establish communications and notify they had safely landed.
After Apollo 11 Buzz Aldrin stayed at NASA and in 1974 replaced Deke Slayton as chief of the Astronaut office.
Aldrin is portrayed by Chris Agos.
While landing Eagle, they couldn't find a smooth surface and landed roughly. They lost transmission with Houston for over 4 hours but managed to reconnect and confirm their landing.
Gene Kranz does not feel confident about Neil turning the Eagle to a vertical position as it would cost them a lot of fuel. He tells this to Wernher von Braun, but the latter is confident. Neil and Buzz Aldrin are authorized to turn the Eagle over, which they do by detaching the top part. They manage to fly again and reach Michael Collins, who was still waiting for them.
