John F Kennedy's famous words about America's quest to be the first to the moon before the end of the 1960s were invoked at least once this week by New Zealand politicians talking about a "big hairy stretch target".
"We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organise and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too," Kennedy said on September 12, 1962, at Rice University football stadium in Houston. "To be sure, all this costs us all a good deal of money."
Nasa's budget had tripled in one year to US$5.4 billion ($7.6b) and the space programme went on to cost US$34b.
That didn't deter Kennedy, though, and his final sales pitch was aspirational as well as inspirational.
"But if I were to say, my fellow citizens, that we shall send to the moon, 240,000 miles away from the control station in Houston, a giant rocket more than 300 feet tall, the length of this football field, made of new metal alloys, some of which have not yet been invented, capable of standing heat and stresses several times more than have ever been experienced, fitted together with a precision better than the finest watch, carrying all the equipment needed for propulsion, guidance, control, communications, food and survival, on an untried mission, to an unknown celestial body, and then return it safely to Earth, re-entering the atmosphere at speeds of over 25,000 miles per hour, causing heat about half that of the temperature of the sun - almost as hot as it is here today - and do all this, and do it right, and do it first before this decade is out, then we must be bold."
