What if the Earth had no moon (part 2)

In a previous post, I mused about what the earth would be like with no moon. You may hear the Moon blamed for things as diverse as reproductive cycles and people’s moods, but in that post, I argued that if all of a sudden, we’d find ourselves without a moon,…

Once more on the search for exoplanets, and Alpha Centauri

This morning I came across this very interesting article on the Centauri Dreams website. By the way, Centauri Dreams, the website of the Tau Zero Foundation, is a very rich source for writers of realistic SF, especially in relation to planetary exploration and interstellar travel. The article summarises results and…

Packing for Mars

by Mary Roach This book is worth reading simply for the laughs. It covers all the niggle and naughty little details about space flight, backed up with details from NASA files. The books focuses on weird and whacky details. Did you know, for example, that rabbits are the only animals…

Communication in space

Electromagnetic waves, whether gamma ray, microwave, radio or visible light frequencies, travel through vacuum at the speed of—well, uhm—light. When on Earth, this means communication is pretty much instant. If the distance travelled in one second by a photon, a light particle, were a string, it would wrap around the…

What would earth be like without the Moon?

The search for terrestrial extrasolar planets in the habitable zone of stars suggests that these planets may not be all that rare. However, examination of the solar system points to the fact that planets with a satellite similar to the Moon are probably a lot less common. It is massive…

Why should we colonise space?

This is, of course, a very good question. It seems that at the moment no one has a satisfactory answer. Space travel is expensive, it’s risky, only few people appear to benefit directly, for a questionable gain, and there are more ‘worthy’ causes to spend our money, so why indeed…
