Is There Anyone Out There ?
As a child I was fascinated by the idea of people from Earth encountering alien lifeforms. I was an avid watcher of Star Trek and the British science fiction TV shows Dr Who and Blake’s 7. I am not alone in my fascination – the idea of humans making contact with intelligent aliens from other planets has intrigued…

Space Tourism into Orbit and Beyond
Getting Into Orbit Although Virgin Galactic’s SpaceShipTwo is likely to be the first spacecraft to offer mass space tourism, it only offers space tourists a short hop into space for a few minutes. (See my previous post from 5 August “The Virgin Galactic Experience” for more information.) To remain in space, a spacecraft must travel at…

The Virgin Galactic Experience
The era of mass space tourism is about to begin. Virgin Galactic’s SpaceShipTwo is about to launch. It is based upon SpaceShipOne, which was an experimental spacecraft which won a $10 million dollar prize for being the first privately built spacecraft to travel to an altitude of 100 km. This, as you may remember from my…

Living on the Moon.
For centuries novelists have written about humans living and working on the moon. One of my favourite science fiction novels is “A Fall of Moondust” by the British author Arthur C Clarke (1917-2008). It was written in 1961, before man had ventured into space and when we knew very little about the Moon’s surface, but set in the…
