Launch from Cape Canaveral; landing southeast
of Bermuda Islands in the Atlantic Ocean.
First
NASA
mission after the
Apollo 1 launch pad fire. It was also a first crew of three
American astronauts. Testflight of the modificated Apollo spacecraft. The crew
performed rendezvous exercises with the upper stage of the Saturn 1-B launch
vehicle and provided the first TV pictures from a U.S. spacecraft.
All
three astronauts developed a bad cold. Additionally one of the three fuel cells
supplying electricity to the craft developed some unwanted high temperatures
and the coolant lines sweated and water collected in little puddles on the
deck. The crew vacuumed the excess water out into space with the urine dump
hose. Looking through the five capsule windows therefore was not good at the
beginning of the mission; two of the windows had soot deposits and two others
had water condensation, but a few days later the windows were adequate. So the
crew could perform observations and navigational sightings with a telescope and
a sextant.
The bad cold of the astronauts caught another problem.
Mucus accumulates, filling the nasal passages, and does not drain from the
head. The only relief is to blow hard, which is painful to the ear drums. So
the crewmen of Apollo 7 whirled through space suffering from stopped up ears
and noses. Aspirin and decongestant tablets helped during the mission. The next
problem was indeed the landing, the cre began to worry about wearing their suit
helmets during reentry, which would prevent them from blowing their noses. The
buildup of pressure might burst their eardrums, several discussions followed
and especially Commander
Schirra was adamant. At least, mission control
won and the astronauts each took a decongestant pill about an hour
before reentry and made it through the acceleration zone without any problems
with their ears.
The most serious problem during reentry was the
overheating of fuel cells, which might have failed when the spacecraft was too
far from Earth to return on batteries, even if fully charged. But each anomaly
was satisfactorily checked out before the next mission.
Crew was
recovered by "
USS
Essex".
