The launch was originally scheduled for
September 28, 1962, but was delayed due of a malfunctioning fuel control valve.
Launch from Cape Canaveral; landing about 275 miles northeast of Midway Island
(for the first time in the Pacific Ocean).
performed several tests needed for longer, more
complex flights. He first took photos during a spaceflight with a Hasselblad
camera, and he checked the manual-proportional mode of the spacecraft control,
although the capsule had an automatic stabilization and control system that was
used for most of the time, including a drifting flight. He also made a
night-yaw maneuver, experimental star observations and a small test to know the
effects of microgravity on orientation. A dialogue between Walter
and CapCom John
could be listened via radio and television by much of the Western world.
All in all it was a nearly perfect mission, only a malfunctioning system at
the beginning, when telemetered signals showed an unexpected clockwise roll
that was quite soon controlled and stabilized. Some problems at the beginning
of the mission with the heat in the spacesuit of Walter
also occurred, but the temperature became more
comfortable with time.
The landing was only 4.5 miles (7.2 km) from the
recovery ship USS
