Using the RTG as a heater turns out to be almost as simple as just sitting it in the rover. The first time, he uses it is to help heat Rover 2 during an expeditionВ to find Pathfinder, a NASA Mars lander whose mission ended inВ 1997, the one that contained the first bug on Mars. To use WatneyвЂ™s own words, вЂњAs with most of lifeвЂ™sВ problems, this one can be solved by a box of pure radiationвЂќ (from logВ entry: sol 199). Watney makes use of this easy energy sourceВ a few times. Its purpose was to generate power for producingВ fuel for the return trip. And of course it contains abundantВ radiation shielding.

The MAV comes with a Radioisotope Thermoelectric Generator (RTG),В a generator containing 2.6 kilograms (5.7 pounds) of plutonium-238.В This gives off just shy of 1500 watts of heat which it then usesВ to produce 100 watts of electricity. Cheating With Radioactivity GPHS-RTG used in the Cassini probe To trick it, he tapes an oxygen filled bag to one of the regulatorвЂ™s sensors,В at which point it thinks thereвЂ™s way more oxygen in the air thanВ there is, and proceeds to allow the oxygen to get down to the desired 1%. The problem is that the HabвЂ™s air regulator that decidesВ how much oxygen is allowed in the air wonвЂ™t let it go below 15%. So he decides to reduce the oxygen to 1%, and then burn off the hydrogenВ a little at a time. On realizing this later he measures the air as 64% hydrogen, a very explosive amount in the presence of oxygen. He fails to notice that some hydrogen gets past the flame in the chimney and accumulates in the air. His efforts donвЂ™t go off without mishap though. The flame itself comes from splinters of woodВ cut from a religious cross belonging to one of the departed astronauts.В Watney ignites the splinter using an electrical spark in the presence of a little oxygen. What it actually leaves is humid air which the HabвЂ™s water reclaimer turns into liquid water.

A flame in the chimney burns the rising H 2, combusting with oxygen in the air and leavingВ water: H 2O.

He creates a chimney from a space suitвЂ™s air hose and arranges it so thatВ the hydrogen (hot from the reaction) rises up it. A side effect of the reaction is the release of some leftover ammonia, NH 3, but this is mentioned in passing as a nuisance.

Separating the N 2В (nitrogen) from the H 4 is easy, he just runs it over an iridium catalyst, also available in the MDV. Hacking a Combustion System Fueling the MESSENGER space probe with anhydrous hydrazineДuring the crewвЂ™s landingВ in the MDV they hadnвЂ™t used up all the fuel, which includes hydrazine, N 2H 4. In the Hab is a device called the oxygenator whose purpose is to take in the CO 2 exhaled by humans and extract the oxygen.В Next he needs the H, in H 2O, the hydrogen and that calls for a chemistry hack. It does this as one step in producing rocket fuel used later to blast off from the surface.ДЇor Watney to get the oxygen from this CO 2 is easy. The bottom portion of the MAV doesnвЂ™t produce oxygen, but it does collect CO 2 from the Martian atmosphere and stores it in liquid form. One component of the precious H 2O molecule is of course the O,В oxygen. They sent up some potatoes with the mission which will sprout roots from their eyes. Do yourself a favor and pick it up after work today. To survive, he has a habitat designed for six, called the Hab, two rovers, the Mars Descent Vehicle (MDV) they arrived in, and the bottom portion of the Mars Ascent Vehicle (MAV), the top portion of which was the rocket that his five crewmates departed in when they left him alone on the inhospitable desert planet.В If you havenвЂ™t read it yet, itвЂ™s easy to finish over a long weekend.

The book has more hacks than the movie so weвЂ™re using the book as the source.ДЇor anyone unfamiliar with the story, Mark Watney is an astronaut whoвЂ™s left for dead, by himself, on Mars. WeвЂ™ve talked about it briefly before, but enough time has passed that we can now write-up the bookвЂ™s juicier hacks while being carefulВ to not give away any plot spoilers. ItвЂ™s been 6 years since the hackerвЂ™s treat of a book, вЂњThe MartianвЂќ by Andy Weir, was self-published, and 2 years since the movie came out.
