Ok, here’s a fun one. Who wouldn’t want to be an Astronaut? It’s pioneering and groundbreaking work. You get to blast off into the wide blue yonder and go places most people (expect for those with a lazy few million dollars), wouldn’t have the remotest hope of coming within several billions miles of.

And then there’s having fun floating above the Earth in a gravity free environment, trying to spot things like the Great Wall of China, and the Sydney Opera House (which should be visible if they’ve kept its tiles pristine white).

And if you’re really lucky, and can get rostered aboard the right rocket, you might even be the first person to set foot on another planet. And that could prove a short cut to your next career, as a celebrity, you know, a star who travelled among the stars, if you play your cards right.

Tempted then are you? Ok, so how does one become an Astronaut, I hear you ask. Well, there are one or two prerequisites.

First up you should at least have the ability to pilot a Jumbo jet (Concorde would be a bonus but is not essential), plus also be familiar with the flight modes of a couple of the latest model jet fighters.

It would also help to have the mental agility of Albert Eienstein, and the constitution of a championship triathlete. You should also be prepared to undergo intrusive medical tests daily, and look forward to “tumble runs”, where you are locked in a small pod, which then is spun around the room at amazing velocity!

You should also enjoy living in conditions akin to a sardine can, and in very close proximity to other people. If you like privacy, and stretching out on the sofa at the end of a long day (whenever days actually end in space - does anyone know?), this job may not be for you.

And if you thought airline food was bad, wait till you try the rocket ship variety. It’s not really food though, it’s a kind of liquid pulp, which you slip through straws out of plastic bags. Mind you, they say it tastes ok, and at least there are no dishes to wash afterwards.

And while pilots will tell you landing a plane is the trickiest part of their job, taking off is the least fun for an Astronaut. Unless you like the feeling of a dozen elephants standing on your chest as you accelerate to Earth escape velocity.

So is it for you? And just going back to the point about being an instant celebrity. Well no, not quite. While the rest us can look forward to 15 seconds of fame, an Astronaut is limited to just ten seconds. That’s the length of the final countdown sequence. After that, I’m sorry, but we’re all watching the rocket, not you!
