I recently re-read Kim Stanley Robinson's Red Mars. It being a fairly weighty book, I spent several weeks engrossed in and thereby inspired by our ongoing desire to visit our closest neighbour.
Its looking more and more likely that a private initiative will put someone on Mars within the next 25 years but in the meantime I have to get my space travel fix by following the astronauts
currently orbiting our speck of dust, who are constantly working towards goals like this.
Three cheers for people in space!
