Lately space science has made a slightly disturbing discovery. Space travel makes you go blind. Really. It’s a bit of a surprise, given that in other ways science has found solutions for most of the biomedical problems of free fall and, along the way, learned an awful lot about osteoporosis, which is a spinoff of … More Don’t space travel. You’ll go blind.
One of my pet irritations with some science fiction is the way authors often succumb to the ‘recency effect’ when inserting the ‘science’ part into their stories. What usually happens is that a recent discovery, looming large and appearing to transform understanding, becomes a raison d’etre or story pivot – except, not long afterwards, that … More Why science fiction dates so horribly, sometimes
An asteroid was discovered last week by astronomers using the University of Hawaii’s Pan-STARRS 1 telescope. It’s moving at a tremendous clip – and is on its way out of our solar system after whipping through on a trajectory that took it inside the orbit of Mercury. The Minor Planets Centre at Cambridge, Massachussets, has … More Did we just rendezvous with Rama?
I don’t know whether to applaud or shudder at Elon Musk’s announcement that Space-X will launch a private ‘moon tourist’ mission late in 2018. I want to applaud because it’s deeply cool, damned bold, and it’s what humanity needs to be doing if we’re to keep any kind of space dream alive. Good stuff. But … More Space X’s trans-lunar mission isn’t a new idea – but it’s cool
It’s SO COOL that we’ve found seven rocky and (broadly) Earth-sized planets orbiting a red dwarf star just 39 light years away. How cool? I’m talking leap in the air and shout ‘this is totally fucking uber-cool‘ scale cool. It’s exciting like nothing else astronomical for a long while. It’s – well, figure this: it’s … More Five cool things about TRAPPIST-1 and its seven worlds
The other day I picked up an interesting snippet about the likely breakfast menu on NASA’s upcoming Orion spacecraft. Because the vehicle is weight- and volume-critical, there are going to be problems packing enough food in for the expected 28-30 day duration asteroid investigation missions. The same issue also applies to storing the – er … More Breakfast in space, on an asteroid, in a tin can
The idea of aliens arriving and promptly attacking us, Independence Day fashion, recently popped up again largely on the back of another Independence Day movie. But it’s also been offered as a warning by no less a person than Stephen Hawking. And when Hawking says something – well, it pays to listen. Is it true … More Would aliens attack us, Independence Day style?
