Destination Mars
VIDEO COMPREHENSION QUESTIONS AND ANSWERS:

1. What are the goals of the first manned mission to Mars?

The goals of the first manned mission to Mars are to look for life, explore for valuable minerals, and test the feasibility of human settlement.



2. If you were invited to join NASA's first manned mission to Mars, how long would you have to be away from school or work? How much of that time would you spend just getting there?

The mission would last approximately two and a half years. Six months of that time would be used in traveling the 250 million miles from the Earth to your destination.



3. In what way are the astronauts headed to Mars similar to the pioneers of the United States?

The astronauts are similar to the pioneers because they will go to Mars with a minimum of resources and live from what they are able to find on the planet, just like the pioneers did when they headed west.



4. Why do scientists feel reasonably confident that Mars can support life?

Meteorites found in Antarctica that are believed to have originated on Mars contained minerals that were seemingly produced by Martian water, as well as evidence of bacteria-like organisms. Evidence of ice caps and riverbeds photographed by previous unmanned missions overwhelmingly suggests that Mars was a wet and active world at one time.



5. What qualities will be the most important for prospective crew members on the first mission to Mars?

Crew members must have the scientific and technical training to operate the spacecraft, land it safely, and perform required experiments. They must also be the kind of individuals who can combat the inevitable boredom and handle the daily risks and stresses of an extended stay in space.



6. What natural resource will provide the energy to power computers, space heaters, and all of the other electrical needs for the astronauts while they travel to and from Mars and while they work on Mars' surface?

The sun. Solar cells similar to the ones found on calculators will collect light energy and either convert it to electrical energy for immediate use or store it in batteries for future use.



7. Why do astronauts spend so much time submerged in large pools of water here on Earth while training for their mission to Mars?

The buoyant force of water helps to simulate the lower gravitational environment on Mars, where astronauts will weigh approximately one-third as much as they weigh on Earth.



8. How will the ultimate success of manned missions to Mars impact humanity?

Humans have always sought to explore the unknown. Successful missions to Mars will extend the boundaries of space exploration and create unparalleled incentive to travel to other planets.
