Celebrating 50 years of The Sky at Night, Patrick 'travelled' back to the show's first ever recording in 1957. The episode then jumped forward to 2057 where the 'virtual' Patrick talked to Dr Chris Lintott and Dr Brian May on Mars. Jon Culshaw's turn as a younger Patrick was uncanny as he recreated Patrick's first words on The Sky at Night.
Dr Chris Lintott finds out how British technology is leading the way in satellite science, while Sir Patrick Moore investigates the threat from space debris that astronauts face in space.
On 14th December 1972, Captain Eugene Cernan left the Moon to return to Earth. He had no idea that, 25 years later, he would still be the last man to have left his footprints on the lunar surface. Dr Chris Lintott travels to the Johnson Space Centre to talk to the Commander of Apollo 17 about his memories of being on the Moon. Sir Patrick Moore looks at lunar samples brought back by the astronauts and talks to NASA scientists about what they discovered.
