Two of the astronauts who took part in the first Moon landing 40 years ago have called for renewed efforts to send a manned mission to Mars.At a rare public reunion of the Apollo 11 crew, Buzz Aldrin and Michael Collins said Mars instead of the Moon should be the focus of exploration. Neil Armstrong, the first man on the Moon, said the race to get to the Moon had been the ultimate peaceful contest. He said it was an "exceptional national investment" for the US and ex-USSR. The trio spoke at an event at Washington DC's National Air and Space Museum to mark the 40th anniversary of their mission.
