LOG ENTRY: SOL 6
I’m pretty much fucked.
That’s my considered opinion.
Fucked.
Six days into what should be the greatest two months of my life, and it’s turned into a nightmare.
I don’t even know who’ll read this. I guess someone will find it eventually. Maybe a hundred years from now.
For the record…I didn’t die on Sol 6. Certainly the rest of the crew thought I did, and I can’t blame them. Maybe there’ll be a day of national mourning for me, and my Wikipedia page will say, “Mark Watney is the only human being to have died on Mars.”
And it’ll be right, probably. ’Cause I’ll surely die here. Just not on Sol 6 when everyone thinks I did.
Let’s see…where do I begin?
The Ares Program. Mankind reaching out to Mars to send people to another planet for the very first time and expand the horizons of humanity blah, blah, blah. The Ares 1 crew did their thing and came back heroes. They got the parades and fame and love of the world.
Ares 2 did the same thing, in a different location on Mars. They got a firm handshake and a hot cup of coffee when they got home.
Ares 3. Well, that was my mission. Okay, not mine per se. Commander Lewis was in charge. I was just one of her crew. Actually, I was the very lowest ranked member of the crew. I would only be “in command” of the mission if I were the only remaining person.
What do you know? I’m in command.
I wonder if this log will be recovered before the rest of the crew die of old age. I presume they got back to Earth all right. Guys, if you’re reading this: It wasn’t your fault. You did what you had to do. In your position I would have done the same thing. I don’t blame you, and I’m glad you survived.
I guess I should explain how Mars missions work, for any layman who may be reading this. We got to Earth orbit the normal way, through an ordinary ship to Hermes. All the Ares missions use Hermes to get to and from Mars. It’s really big and cost a lot so NASA built only one.
Once we got to Hermes, four additional unma
Hermes is powered by ion engines. They throw argon out the back of the ship really fast to get a tiny amount of acceleration. The thing is, it doesn’t take much reactant mass, so a little argon (and a nuclear reactor to power things) let us accelerate constantly the whole way there. You’d be amazed at how fast you can get going with a tiny acceleration over a long time.
I could regale you with tales of how we had great fun on the trip, but I won’t. I don’t feel like reliving it right now. Suffice it to say we got to Mars 124 days later without strangling each other.
From there, we took the MDV (Mars descent vehicle) to the surface. The MDV is basically a big can with some light thrusters and parachutes attached. Its sole purpose is to get six humans from Mars orbit to the surface without killing any of them.
And now we come to the real trick of Mars exploration: having all of our shit there in advance.
A total of fourteen unma
Naturally, they didn’t send us to Mars until they’d confirmed that all the supplies had made it to the surface and their containers weren’t breached. Start to finish, including supply missions, a Mars mission takes about three years. In fact, there were Ares 3 supplies en route to Mars while the Ares 2 crew were on their way home.
The most important piece of the advance supplies, of course, was the MAV. The Mars ascent vehicle. That was how we would get back to Hermes after surface operations were complete. The MAV was soft-landed (as opposed to the balloon bounce-fest the other supplies had). Of course, it was in constant communication with Houston, and if there had been any problems with it, we would have passed by Mars and gone home without ever landing.
The MAV is pretty cool. Turns out, through a neat set of chemical reactions with the Martian atmosphere, for every kilogram of hydrogen you bring to Mars, you can make thirteen kilograms of fuel. It’s a slow process, though. It takes twenty-four months to fill the tank. That’s why they sent it long before we got here.
