How does Mark Watney make water from hydrazine?
Watney takes the risk of creating his own water by using his oxygenator (a device that creates oxygen from carbon dioxide), extracting hydrogen from the crew’s unused hydrazine fuel (from the MDV, or Mars Descent Vehicle), and burning them to create the extra water he needs to nourish his potatoes..
How do you hydrate hydrazine?
To a copper or silver retort a well mixed mixture of 100 g of dry hydrazine sulfate and 100 g of powdered potassium hydroxide and 5 ml of distilled water were placed (distillation flask made of glass also could be used, but molten potassium hydroxide aggressively acts upon glass).
How dangerous is hydrazine?
Symptoms of acute (short-term) exposure to high levels of hydrazine may include irritation of the eyes, nose, and throat, dizziness, headache, nausea, pulmonary edema, seizures, and coma in humans. Acute exposure can also damage the liver, kidneys, and central nervous system in humans.
Can we breathe on Mars?
Mars does have an atmosphere, but it is about 100 times thinner than Earth’s atmosphere and it has very little oxygen. The atmosphere on Mars is made up of mainly carbon dioxide. An astronaut on Mars would not be able to breathe the Martian air and would need a spacesuit with oxygen to work outdoors.
Where is hydrazine used?
Hydrazine is mainly used as a foaming agent in preparing polymer foams, but applications also include its uses as a precursor to polymerization catalysts, pharmaceuticals, and agrochemicals, as well as a long-term storable propellant for in-space spacecraft propulsion.
How do you make hydrazine?
hydrazine preparation …is best prepared by the Raschig process, which involves the reaction of an aqueous alkaline ammonia solution with sodium hypochlorite (NaOCl). 2NH3 + NaOCl → N2H4 + NaCl + H2O This reaction is known to occur in two main steps.
How will Mars get water?
On Mars, water can be extracted from the soil. … Since Mars has gravity, water can be used in the same way as on Earth. Each astronaut will be able to use about 50 liters of water per day. The water will be recycled, which takes much less energy than extracting it from the Martian soil.
Does Mars have oxygen?
Mars has only a thin atmosphere, with a surface pressure less than a hundredth of the Earth’s. Even worse, it is 96% carbon dioxide with only about 0.1% oxygen. … The carbon monoxide would be unwanted, and would be vented back into the martian atmosphere.
Is Hydrazine a base or acid?
Hydrazine is also called as Diamine or Diazane or Nitrogen hydride and is a strong base.
Is hydrazine a weak base?
What does hydrazine smell like?
Hydrazine is a chemical compound that has an ammonia- like odor. It has physical properties similar to those of water. It is used as rocket fuel and also the blowing agent in Page 3 preparing polymer foams. Hydrazine (N2H4), reductant, is an alkali molecular compound smelling like ammonia.
Can you make water from hydrazine?
Matt Damon’s character took hydrazine from the rocket fuel and dissociated it into nitrogen and hydrogen, which you can do, and he burned the hydrogen with oxygen to make water.
Can plants grow on Mars?
Unlike Earth’s soil, which is humid and rich in nutrients and microorganisms that support plant growth, Mars is covered with regolith. … Plants on Earth have evolved for hundreds of millions of years and are adapted to terrestrial conditions, but they will not grow well on Mars.
How did NASA realize that Mark is still alive?
In the film version, they discover that he is still alive by noticing two things on the satellite imagery: … In the film, the potatoes were grown completely inside the HAB, so no external tents would have been seen by the satellite.
Who dies in Martian?
Mark WatneyBack on Earth, NASA Director Teddy Sanders (Jeff Daniels) holds a press conference to announce that while the Hermes crew succeeded in leaving Mars, Mark Watney was lost, and he is declared dead. Watney wakes up on Mars on what is Sol 21 (mission day 21) after the storm has passed.
Is hydrazine hydrate explosive?
Hydrazine is a FLAMMABLE LIQUID that may self-ignite at low temperatures. Use dry chemical, CO2, water spray or alcohol-resistant foam as extinguishing agents. Use water spray to disperse vapors. POISONOUS GASES ARE PRODUCED IN FIRE, including Ammonia and Nitrogen Oxides.
Did Mars ever have water?
It is widely accepted that Mars had abundant water very early in its history, but all large areas of liquid water have since disappeared.
How much does hydrazine cost?
Typical cost is around $100/lb. The real cost of hydrazine is probably in the protective measures we take to deal with it.
