Ridley Scott’s The Martian premiered in space before premiering on Earth. That’s… oddly appropriate, actually.

Ridley Scott’s upcoming, star-specked (get it? Cause, space?) sci-fi adventure The Martian premieres next month. But actual astronauts have already watched the movie, in space.

NASA astronaut Scott Kelly tweeted (because that’s also a thing you can do from space now) a picture of himself watching the movie from the International Space Station:

We have to say, watching a movie about a guy who gets stranded on Mars, while actually being off-planet, takes more than your average level of guts. But then, this guy is an astronaut, so what did we expect?

Meanwhile, back on Earth, scientists have declared the science of The Martian — which sees Matt Damon’s astro-botanist Mark Watney “science the sh**” out of everything when his crew accidentally leave him behind — to be less than air-tight. (Which, if you’ve read the novel, you’ll know is no good at all.)

The Guardian has presented some basic inaccuracies of the book written by Andy Weir, which very much puts The Martian into the realm of science fiction:

First of all, the terrible dust storm Watney encounters wouldn’t actually be that terrible, as, “the red planet’s thin atmosphere would reduce winds to barely a light breeze,” according to The Guardian’s quoted expert, John Logsdon.

Watney spends a lot of his time trekking around the red planet, but Logsdon claims that he wouldn’t actually be walking, but rather hopping around like on the moon.

And finally — and this one’s kind of a bummer — the excess radiation experienced by both Watney and his fellow crewmembers would probably kill them all. So, that sucks.

Sometimes fiction really is preferable to fact, huh?

It should be noted that Andy Weir’s The Martian has generally been praised for its relative scientific accuracy. We’re sure everyone will enjoy this movie regardless of these minor sticking points!

‘The Martian’ premieres October 2, 2015 in a galaxy near you. It stars almost every single Hollywood actor ever.
