The Mercury-Redstone Launch Vehicle, designed for NASA's Project Mercury, was the first American crewed 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. Wikipedia

AG-3: Opens the parachute.
AG-4: Ingnite the escape tower and separate the capsule when things goes wrong
AG-5: Separate the escape tower to land safely
AG-10: Reentry RCS to orientate retrograde

And slider 1: retract the tower

    I think I was on my fourth attempt to get it into orbit before I realized the problem: it's a freakin' Mercury-Redstone. I was trying to orbit a sub-orbital craft. :FACEPALM:
    Well, its definitely has an accurate amount of fuel. heh

    Alan Shepard and Gus Grissom were pretty damn brave to have ridden on top of what's basically a stretched V2.
