Michael Collins obituary

Astronaut and pilot of the command module Columbia during 1969's Apollo 11 mission

On 20 July 1969, Michael Collins, who has died aged 90, became the most solitary human in the universe - even if he derided that categorisation as phony philosophy". He orbited the moon alone, inside Apollo 11's command module Columbia, and out of touch with ground control for 48 minutes on each orbit. Meanwhile, and more famously, Neil Armstrong and Buzz Aldrin were becoming the first men to set foot on that rock, some 240,000 miles away from Earth.

As the command module pilot, on $17,000 a year, Collins was, he later wrote half-jokingly, the navigator, the guidance and control expert, the base-camp operator, the owner of the leaky plumbing - all the things I was least interested in doing". He was also, thought Aldrin, probably Nasa's best-trained command module pilot.
