Alfred Worden to date the least talked about of the Apollo 15 astronauts, opened the hatch, stepped out and walked 500 miles (800 kms) of the way home on Thursday (4 August). Worden, who had circled the moon while astronauts David Scott and James Irwin spent three historic days on the moon, had the starring role as the floated in space. Tethered to the Apollo 15 spacecraft, it was easily the farthest out in space that man has floated free-194,300 miles (316,700 kms).
The purpose of the spacewalk was to retrieve two cassettes of exposed film from cameras in the service module. The cameras were used to photograph vast areas of the moon for mapping purposes. The service module and cameras were to be jettisoned, prior to re-entry into the earth's atmosphere and splashdown on Saturday (7 August).
SYNOPSIS: Apollo Fifteen astronaut Alfred Worden, cramped in the spaceship Endeavour for ten days, went for a walk on Thursday--nearly two-hundred thousand miles form East Tethered to the Apollo Fifteen spacecraft, its three-thousand mile velocity helped Worden cover five-hundred miles in dead space. As the astronaut stepped out of the spacecraft, his heart rate soared from a normal seventy beats a minute to one-hundred and thirty. Soon the heart-rate subsided into the nineties, then to eighty-Five. Worden retrieved two cassettes of exposed film, from cameras that photographed vast areas of the moon for mapping purposes. He also checked some minor fault affecting some of the instrument.
The whole operation, from operation to closing of the hatch, lasting less than twenty-one minutes. Apollo Fifteen mission banners had allowed a maximum of one hour for the walk.
