The Hab, short for “The Mars Lander Habitat”, are a series of artificial living quarters that were constructed before the Ares III manned mission to Mars landed It is designed to house six astronauts for 31 Martian Days (Sols)
What is the Hab in The Martian quizlet?
The hab, short for Mars Lander Habitat is the closest that Mark has to a home on Mars
Is the Hab in The Martian realistic?
A good chunk of The Martian takes place in Watney’s habitat, affectionately known as the Hab The Hab is based on Human Exploration Research Analog (HERA), a self-contained habitat that NASA crews train in for long-duration deep space missions HERA is a self-contained environment that simulates a deep-space habit
What is the RTG in The Martian?
The Mars Ascent Vehicle in “The Martian” is powered by a radioisotope thermoelectric generator (RTG), which converts the heat of the radioactive decay of plutonium-238 into electricity This RTG is buried a safe distance away from the pioneers’ living quarters
Why did Watney take Sojourner back to the hab?
Watney has found the Pathfinder lander and the Sojourner rover that accompanied it to Mars He’ll bring both back Watney explains that Sojourner is useful to him because it has six independent wheels, which NASA could control—they could potentially work out a communication code using the moving wheels
How does NASA find out Watney is alive?
NASA eventually discovers that Watney is alive when satellite images of the landing site show evidence of his activities; NASA personnel begin devising ways to rescue him, but withhold the news of his survival from the rest of the Ares 3 crew, on their way back to Earth aboard the Hermes spacecraft, so as not to
What does 12 G’s mean in the Martian?
On the other hand, 12 G-Force aceleration during the takeoff is exaggerate Escape velocity on Mars is 5 km/s and on Earth ~11 km/s, so the G-force aceleration loads for takeoff would be typically 3g on Earth and 1g on Mars 12g, even for 30 seconds, might be extremely dangerous for anybody
How did the HAB explode in the Martian?
At the end of the chapter, when Watney reenters the Hab after a short walk to the rover, the airlock blows open, hits Watney in the face, and causes the Hab to depressurize instantly and “collapse” on itself Watney can’t believe his bad luck
Where is the HAB located in the Martian?
The artificial living habitat, known as the Hab, is where the crew of Ares III is stationed on Mars Max looked at a small one-man Hab at the Johnson Space Center and expanded on the design to create a full-scale habitat that could accommodate six crew members
What did Watney use the RTG for?
Watney experienced another source of radiation when he dug up the Mars outpost’s radioisotope thermoelectric generator (RTG), to use the instrument’s decaying plutonium as a heat source Turner didn’t have the exact details on the system, so he didn’t calculate how this might have affected the astronaut
What does the atmospheric regulator do in the Martian?
Atmospheric regulator A machine that monitors the molecular gas concentrations in the air, removing and resupplying CO2 and O2 as necessary
Can RTGs explode?
Because RTGs use radioactive decay, each launch of any vehicle with an RTG requires Presidential approval Given that they are the only reasonable way to power satellites beyond the orbit of Mars (as solar panels stop becoming effective), RTGs are necessary RTG’s can not explode like a nuclear weapon
What was the first thing Mark Watney did when he got to the hab?
The MAV takes 18 months to make fuel How did Mark make water? First, he separated the hydrogen from the hydrazine Then, he combined the hydrogen with the oxygen that was already in the air
How does Watney seal the hole?
According to Watney, if he does not use his heater in the rover he will be “slowly killed by the laws of _______” How does Watney seal the hole caused by the airlock explosion? with plastic sheeting What happens to the rocket that is carrying Watney’s extra food?
How does Watney solve the heat problem in the rover?
The Martian In the movie, astronaut Mark Watney finds a creative solution to stay warm on frigid Mars using a power system called an RTG — a radioisotope thermoelectric generator — a “space battery” that converts heat from the natural radioactive decay of plutonium-238 into reliable electrical power
How long is a sol?
Mars is a planet with a very similar daily cycle to the Earth Its ‘sidereal’ day is 24 hours, 37 minutes and 22 seconds, and its solar day 24 hours, 39 minutes and 35 seconds A Martian day (referred to as “sol”) is therefore approximately 40 minutes longer than a day on Earth
How many swear words are in the Martian movie?
In a weird way those four words represent the movie: “I’m pretty much f—ed” It’s not “I’m f—ed” “I’m not giving up hope” is really what it’s implying
How strong is Martian wind?
Surface winds typically move about 16 to 32 kilometers (10 to 20 miles) per hour The Viking Landers measured speeds of up to 113 kilometers (70 miles) per hour during dust storms
What is meaning G-Force?
Definition of g-force : the force of gravity or acceleration on a body pilots experiencing strong g-forces during takeoff
What is the gravity on Earth in GS?
The force of Earth’s gravity is the result of the planets mass and density – 597237 × 1024 kg (131668×1025 lbs) and 5514 g/cm3, respectively This results in Earth having a gravitational strength of 98 m/s² close to the surface (also known as 1 g), which naturally decreases the farther away one is from the surface
What g means space?
Mar 11, 2016 Gs stand for gravities
