In 1961, John F. Kennedy told Congress: “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.”
But on 21 July 1969, at 17:54 UTC, the spacecraft Eagle lifted its metaphorical wings and took off from the Moon (well, the upper ascent stage took off, as shown in the photograph below). There followed a rendezvous with Columbia, a flight back to Earth, and an eventual splashdown on 24 July. Mission accomplished.
Fifty years ago, on 20 July 1969, at 20:17:40 UTC, the spaceship Eagle landed on the Moon. Here is the landing site – below, as it was, and above, as seen by the Lunar Reconnaissance Orbiter Camera (LROC). Clearly visible in the LROC image, and illustrated with inset photographs from 1969, are:
Fifty years ago, on 19 July 1969, the spaceship duo Columbia / Eagle entered orbit around the Moon, roughly 3 days and 4 hours after its launch, as part of the Apollo 11 mission. Eagle (with Neil Armstrong and Buzz Aldrin) went on the land on the moon on 20 July while Columbia (with Michael Collins) continued to orbit the moon. When he announced the space programme, Kennedy had said:
“We choose to go to the moon. 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 organize 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.”
Much can be learned from doing hard things, and an enormous amount was learned from the space programme. Solar car teams also learn a great deal from doing hard things. Fifty years after Columbia and Eagle entered orbit, also after hard effort, the University of Michigan Solar Team’s solar car Electrumarrived in public view (at 17:30 Michigan time). They intend to win too!
Fifty years ago, on 16 July 1969, a Saturn V rocket carrying three men (Neil Armstrong, Buzz Aldrin, and Michael Collins), plus the command module Columbia, and the lunar module Eagle, took off from Florida, en route to the first human landing on the moon (above).
Fifty years later, the Dutch Vattenfall Solar Team launched their 10th solar car, Nuna X (below). Catamaran-style solar cars seem to have reached an optimum: the front of Nuna X looks a lot like Nuna 9 and the rear looks a little like Twente’s Red E and Agoria’s Punch 2 – but only on the left side! The new car weighs just 135 kg (298 lbs), which is probably the lightest ever solar car. I think that Twente, Agoria, and everybody else will have their work cut out trying to outrace this latest car from Delft!
In 1994, I finished up a three-year lecturing contract at the National University of Singapore, and returned to Australia. That year saw the launch of the Netscape Navigator web browser (I wrote my first web page) and the opening of the Channel Tunnel between France and the UK (I was to take a train through that tunnel some years later). A plethora of movies was released – Stargate was one of the better ones:
