Background: Apollo Fifteen was launched on Monday (26 July) from Cape Kennedy, on what will be the longest and most difficult mission of the moon landing series.
Astronauts David Scott, Alfred Worden, and James Irwin were to have spent the day before launch relaxing in the sun. Only Worden was successful in that endeavour. Astronauts Scott and Irwin spent part of the day practicing in a mock-up of their Lunar Rover vehicle.
The two astronauts will spend nearly three days on the moon making three separate excursions out on the lunar surface with their electrically powered car. This is the first time a vehicle will be driven on the moon, and the astronauts have rehearsed long and hard in the Lunar Rover simulator.
SYNOPSIS: Astronauts David Scott and James Irwin are scheduled to begin the first of three excursions on the lunar surface on Saturday. For the first time men will be making use of a vehicle for exploration on the moon. Scott and Irwin spent part of the day before blastoff in the Lunar Rover simulator.
The simulator is an exact replica of the Lunar Rover the astronauts will use on the moon. In order to duplicate conditions they are likely to encounter, a series of television screens display a moving picture of the lunar surface. Either astronaut many move the controls -- simulating movement of the lunar rover, as it encounters various physical obstacles. A television camera will be mounted on the real Lunar Rover, the beam back pictures of what the astronauts see on the moon. Remotely controlled from Earth, it will track the astronauts when they leave the Rover.
A five-mile limit has been imposed on the astronauts' lunar excursions, in case the Lunar Rover breaks down and they have to walk back to their spacecraft.
