Two moonwalks

Over two moonwalks, Conrad and Bean spent more than seven hours on the surface. They raised the flag, deployed the ALSEP science station and walked over to Surveyor 3, from which they removed parts for scientists on Earth.

The ALSEP station, powered by its own nuclear source (an RTG), measured moonquakes, the solar wind and the magnetic field, sending back data for years after the crew left. Early on, Bean accidentally pointed the colour TV camera at the Sun and burned it out for good — viewers on Earth lost their picture from the surface.

At Surveyor 3 the astronauts cut away the television camera and other parts and brought them back to Earth. Scientists studied how two and a half years on the Moon had affected terrestrial materials — and puzzled over whether Earth bacteria had survived on the probe.
