Mercury-Redstone 4 was the fourth mission in the Mercury-Redstone series of flight tests and the second U.S. manned suborbital spaceflight. It was the next step in the progressive research, development and training program leading to the study of man’s capabilities in a space environment during manned orbital flight.

The main configuration differences from the MR-3 spacecraft was the addition of a large viewing window and an explosively actuated side hatch. During the flight, the spacecraft attained a maximum velocity of 8,270 km/hour and an altitude of 189 km. The duration of flight was 15 minutes and 37 seconds.
