He was also a Project Gemini and an Apollo program astronaut. Grissom was the second American to fly in space, and the first member of the NASA Astronaut Corps to fly in space twice. In addition, Grissom was a World War II and Korean War veteran, U.S. Air Force test pilot, and a mechanical engineer.

Mercury-Redstone 4

  • Type: Human Exploration

Rocket


Chrysler Redstone MRLV

The Mercury-Redstone Launch Vehicle, designed for NASA’s Project Mercury, was the first American manned space booster. It was used for six sub-orbital Mercury flights from 1960–61; culminating with the launch of the first, and 11 weeks later, the second American (and the second and third humans) in space. The four subsequent Mercury human spaceflights used the more powerful Atlas booster to enter low Earth orbit.

A member of the Redstone rocket family, it was derived from the U.S. Army’s Redstone ballistic missile and the first stage of the related Jupiter-C launch vehicle; but to human-rate it, the structure and systems were modified to improve safety and reliability.
