Does Mark get fuel to make water from the rocket that the other crew members had used to escape?
In The Martian, Mark makes water using a couple of things. I'm not sure if I saw it correctly, but it seemed to me that he took the rover and drove to the rocket to get fuel from it. However, isn't that the rocket the other crew members used to fly to the bigger space station? In other words, did the writers screw up and let Mark use fuel from a rocket that had previously left Mars?
Best Answer
He didn't. He used the hydrazine tanks from the MDV (Mars Descent Vehicle) - emphasizing that the descent vehicle is completely separate from the MAV (Mars Ascent Vehicle), which is what the crew used to leave at the beginning of the film. Like the MAV IV (which Watney used to leave Mars), the MAV III had been sent in advance of the mission to create fuel, so they didn't depart in the same ship they arrived in.
From the book, "Log Entry Sol 30":
The MDV has 292 liters of juice [hydrazine] left in the tanks. Enough to make almost 600 liters of water!
Yes, this is from the book but the same was done in the film.

How did Mark create water in the Martian?
There's also the problem of hauling up water, which has yet to be found in plentiful liquid form on Mars. In \u201cThe Martian,\u201d Damon's character, astronaut Mark Watney, produces water by burning leftover rocket fuel and extracts the hydrogen from the resulting chemical reaction.What does Mark make rocket fuel out of the Martian?
SPU PO3 \u2013 The Martian Nina Groenveld | VT4A Making water using hydrazine: In the movie, astronaut Mark Watney used hydrazine from the rocket fuel and separated it into nitrogen and oxygen. The formula is N2H4 \u2192 N2 + 2H2. After this he burned the hydrogen with oxygen to make water. The formula is 2H2 + O2 \u2192 2H2O.What does Mark make rocket fuel for the MAV out of?
The MAV makes its own fuel from the Martian atmosphere, but it's limited by how much hydrogen it has. It brought enough to make 19,397 kilograms of fuel, as it was designed to do.8 STUPID MISTAKES everybody makes in Kerbal Space Program
