Mortal as I am, I know that I am born for a day. But when I follow at my pleasure the serried multitude of the stars in their circular course, my feet no longer touch the earth - Ptolemy
The Space Race (1640)
Forty years ago this week the human race passed a milestone in its history when Mission Commander Neil Armstrong stepped onto the Moon. There are edited entries on h2g2 which document the event in detail, but I'd like to tell you about how one man dreamed of a journey to the Moon during the Jacobean era.
British inventor John Wilkins (1614 - 1672) was the brother-in-law of Oliver Cromwell, a name engraved on the memory of many schoolchildren, but Wilkins deserves his own place in history. Wilkins wrote a book entitled Discovery of a World in the Moon in 1638, where he spoke of a race of aliens called Selenites1. Wilkins envisioned travelling to the Moon and opening a trade link with these creatures. He dreamed of launching a wooden chariot, complete with wings made from feathers, to the Moon. He even worked out that he'd need gunpowder for the launch, and to give extra boosting power, he'd build his machine atop a coiled spring. Wilkins built flying machines of wood and tested them in the grounds of Wadham College, Oxford, where he was warden (and, eventually, Dean).
During the 1640s such a journey to the Moon seemed within the realm of possibility as the vacuum of space was unknown then. People were only just getting used to the idea of the Copernican system (heliocentrism) which was proved beyond doubt by the telescopic observations of Galileo in 16092. By the time of Wilkins' death the field of astronomy had advanced to such an extent that a trip to the Moon (and back) was deemed impossible.
Just a reminder that on Sunday, 26 July there is an astronomically-themed day at Syon Park in West London, as part of the IYA2009 celebrations. A detailed programme is now available. Do attend if you can, the itinerary looks fascinating. I only wish I could go, but Deke is hoping to attend and if he can I'll post his comments in the next edition of BATS.

On 27 August, a red supergiant star of the first magnitude, Antares (alpha Scorpii), AKA Cor Scorpionis 'the heart of the scorpion', will be half a degree south of the Moon. From the vantage point of North America (except Canada), an occultation will occur. Such alignments were considered auspicious in olden times and horoscope writers still earn a living promoting their astrological thoughts. It would be quite easy to connect this 'event' with a famous Scorpio, namely the Prince of Wales. The Moon rules Cancer, which is the birthsign of his wife, Camilla, and also motherhood: Prince Charles' Mum is, of course, HM The Queen.
