Notes: This was the first flight of a Saturn IB launcher, which consisted of an uprated version of the first stage of the Saturn I (launched successfully 10 times between October 1961 and July 1965) and a new second stage, the S-IVB, which would later become the third stage of the Saturn V. The flight was suborbital, reaching a maximum altitude of 488 kilometers (303 miles), and carried into space a Block I Apollo command and service module that had been modified specifically for this launch.

This mission tested the ignition and restarting of the service module engine and tested the structure and heat shield of the command module with a reentry that was slower (29,000 km/h, 18,000 mph) but steeper than those planned for crewed lunar missions.
