Humans on Mars has been full of curiosity and desire, in various science fiction movies, Mars also appear to live the second planet.
In October this year, and there's a Mars Expedition and life as the theme of the film The Martian (Mars rescue) will be released. Astronaut mate·woteni (played by Matt Damon) in a Mars Expedition in the forgotten team, he must make full use of the existing resources and equipment, survive on Mars, and sending a distress signal to Earth.
Inspiration for the film is a fiction, and the author of the novel used to be a programmer. Programmers may also be because the author background, the film outside of the wild imagination, most of the science-fiction elements can be found in the real ... NASA (United States NASA) published a paper, introduces the film 9 and now NASA has been or is about to use the technology.
1 home
In the film, Matt spent most of his time on Mars in the homes, landed on Mars in the future also need similar accommodation.
Lyndon Johnson Space Center of NASA, astronaut "training Simulator for human research (HERA – Human Exploration Research Analog) for a long period of time in space training simulation. HERA had the astronauts ' living space, work space and clean space. Now astronauts will live for 14 days in HERA, and possible future 60-day experiment.
2, farm
In the film, Matt home into a self-sufficient farm and grow potatoes.
International space station astronauts can now enjoy plenty of fruits and vegetables, in addition to transport, in addition to the international space station and a Veggie system can allow astronauts to grow vegetables. This system contains the right light, fertilizer and so on. In 2014, the astronauts have used it in space have been growing lettuce.
3, water cycle
Due to the Martian surface without water in the film, Matt should be particularly careful in the use of water, but also limited water sources need to be recycled as much as possible.
The international space station, astronauts ' sweat, tears or urine will not be wasted. The ISS water recovery system (Water Recovery System) will collect all the water for the astronauts to use again. A image of the astronaut had said: "tomorrow's coffee-coffee from yesterday. "
4, oxygen
On Mars, Matt does not like people on the planet get a breath of fresh air. Once outside, he needed an oxygen tank on his back. But first, he needed oxygen in the home.
Oxygen-making system on the international space station, it can continue to provide oxygen for the astronauts. It mainly makes oxygen from water using electrolysis. And oxygen-making process has been optimized for future Mars exploration, NASA was trying to extract oxygen from the atmosphere of other components.
5, suit
On Mars, Matt wore suit most of the time, this dress would have to be warm and malleable and comfort features such as reliable. Too bulky space suit of astronaut activities cause a lot of influence.
Now, NASA is working on a suit worn by astronauts on Mars space suit, the most important function is to enable astronauts to Mars free to walk and collect rock samples on Mars. NASA has experiment a myriad of materials, is still balancing robustness and extensibility of different materials. Another point is, make sure that gray entered the spacecraft to Mars impact systems and the health of astronauts, which may need when the astronauts entered the spaceship or landing, spacesuit can automatically fall off, remain outside the cabin.
6, and the Rover
In the Mars rescue in the film, Matt in order to survive, or to train some alterations to the roving vehicle.
True exploration of Mars, the Rover is a necessary piece of equipment. This expedition to Mars in all parts of the team as much as possible, and learn more about Mars. Now NASA is testing their multi-functional space exploration vehicle (MMSEV), through a variety of tests to solve the problem now known and unknown risks. Factors to consider include driving distances, driving safety, speed, radiation protection, and so on.
7, an ion thruster
In the movie, Mars exploration team used ion thrusters to accelerate through the distance of 2.8 million miles.
Principle of ion thrusters is ionized gas, then after the charged ions are accelerated with electric Jet, in its reaction in their rockets. It is now practical rocket technology, one of the most economic. This technology will allow NASA spacecraft used less energy to complete a long distance flight. Ten standard data industry bid farewell to leap
8, solar panel
Mars has no gas stations, no power plants almost no wind, the best way to power through solar energy. In the film, Matt on Mars in order to survive, using non-conventional solar panels being used.
ISS now has four solar panels, generating capacity reached 84-120 million, enough for 40 families. Space station does not need a lot of power, but the extra power generation can in case of an accident, not a situation of power shortage. This system is very reliable and has been running for 15 years. If you need more distance in space navigation, solar energy is one of the important sources of power.
9, radioisotope thermal electric
Radioisotope thermoelectric generators (RTG) is a radioactive decay energy generators.
In the movie, Mars exploration team at special away buried in radioisotope thermoelectric generators in their homes to prevent leakage of radioactive material. In fact, Mars is there may be a risk of radioactive elements, more serious than the radiological risk associated with radioisotope thermoelectric generators.
In the past 40 years, NASA used radioisotope thermoelectric generators to provide electricity for 20 times cosmic, including journey of Apollo. Curiosity Rover is the next generation of power systems. Space mission might need a better source of energy in the future, may be combined with radioactive material, solar and nuclear energy.
