What challenge should we set for our generation?
Forty years ago today, a little after half past nine in the morning, Neil Armstrong, Buzz Aldrin and Michael Collins blasted off from Cape Canaveral on board Apollo 11 on their mission to the moon.
It was a historic moment that grabbed the attention of the United States and the world.
When they safely arrived a few days later they had fulfilled President John F Kennedy's aim of reaching the moon by the end of the 1960s.
In his famous speech given before a joint session of Congress on May 25th 1961, JFK had said:
"I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth."
So what kind of challenge should we set for our generation?
What similarly ambitious goal should we commit ourselves to achieving before a decade is out?
