Forty years after making history, the crew of the first successful flight to the Moon have called for a new push into space. The public’s fascination with space seems undimmed: 7,000 people applied for just a few hundred tickets to see the Apollo 11 astronauts together again at Washington’s National Air and Space Museum. Neil Armstrong, Michael Collins and Buzz Aldrin said the dream must not be allowed to die.“The best way to honour and remember all those who were part of the Apollo programme is to follow in our footsteps; to boldly go again on a new mission of exploration,” said Edwin “Buzz” Aldrin, the second man on the Moon. Armstrong’s original moonwalk was the first time Man had stepped on another celestial body. Now the Apollo 11 crew is looking further afield, echoing President Obama’s call to put a man on Mars in the next 20 years.
