Astronauts Borman and Lovell, who had been flying most of their mission in underwear, were now in their space suits. If the two spacecraft inadvertently bumped, their skins might rupture and the astronauts would need protection against decompression of the cabin. Meanwhile, Schirra made another posigrade burn to lift his ship into a higher orbit that would lead to its meeting with Gemini...
Eventually, Gemini 6 maneuvered into a safer orbit that kept the ships between 25 and 48 miles apart while their tired crews slept. Next morning, an hour before he fired retrorockets for Gemini 6's trip back to earth, the irrepressible Schirra solemnly reported sighting an unidentified satellite in a low trajectory in polar orbit. It was trying to contact him, he told Mission Control in Houston. Then, before Chris Kraft & Co. had time to recover, he pulled out a harmonica and played Jingle Bells...
Eyeball Maneuvers. From the time that Schirra made the final major thrust that moved his ship up toward Gemini 7's circular orbit, Gemini 6 was completely on its own, freed from direct guidance by Houston, largely dependent on its on-board computer, its radar and Command Pilot Schirra's "eyeball" maneuvering. Both Schirra and Stafford literally had their hands full. Schirra's left hand was on the OAMS (Orbital Attitude Maneuvering System) translation stick, which controls Gemini's 85-Ib. and 100-lb. thrusters, and is-in NASA parlance-"direction oriented." When he wanted...
...short range, where the thrusts are small, there is little time for orbital mechanics to take hold, and Schirra was able to largely ignore their strange effects and allow his pilot's instincts to take over. After blipping his thrusters to edge closer to Gemini 7, he fired short reverse blasts to come to a stop, since there is no friction in space to slow him down. Back and forth, up and down, he maneuvered with a precision that brought expressions of admiration from Borman and from ground control in Houston, which noted that at rendezvous he had used...
...Schirra had predicted, it was "a piece of cake...
