Our Mission (Driving Question)
A spacecraft that travels through space and collects information.
A rover is a vehicle for exploring the surface of planets.
Partially reusable low Earth orbital spacecraft operated by the U.S. NASA
In order to go to Mars, we need to make sure we're sending the right people for the job!
The difficulties of space travel
~Variations in air pressure: We rely on air pressure to survive and almost no pressure in space.
~Lack of oxygen: No oxygen in space.
~Absence of water/food: Food is unappetizing and hard to eat an food/water is too heavy.
~Extreme Temperatures: Extreme cold temperatures on Mars.
~Radiation exposure: Risks of cancer,damage to central nervous system,cataracts,acute radiation sickness, and hereditary effects.
~Micrometeoroids: Can damage spacecraft small but very fast.
~Distances between objects: Stress,depression,anxiety,interpersonal conflicts,insomia, and phychosis.
~Space Suit: makes movement easier for lack of gravity, maintains earth-like air pressure, complete with an oxygen tank so you can breathe, layers of thick fabric to protect you from extreme temperatures, reflects rays to protect you from radiation, and shields you from micrometeoroids and other space dangers
~Water: Water will be recycled to help with conservation
~Space Food: This food is easily packaged and packed and has a long shelf life
~Rover: A vehicle for exploring the surface pf moons and planets
~Rocket: A spacecraft that gets power from an engine full of chemicals propellants that moves because of action-reaction forces
~ISS: An orbiting space station built for 16 nations used for scientific and space research.
~Observatory: A place equipped for observation of natural phenomena
~Telescope: An optical instrument for viewing distance objects
~Space Probe: An unmanned spacecraft designed to explore the Solar System and send information back to Earth
~Space Shuttle: A reusable spacecraft designed to transport people and cargo between Earth and space
~Satellite: Spacecraft that orbits Earth
~Space Station: A large artificial facility designed to be occupied for long periods and serve as a work space to conduct research
According to businessinsider.com, here is another suggested packing list for astronauts:
There is no washing machine in space. Water is heavy and therefore expensive to take on a 34 million-mile journey above Earth. That pretty much means what you think it does — astronauts have to wear the same clothes for several days in a row before they can put on a clean outfit.
So how does one pack for space?
Here's the packing list:
1 pair of shoes for the treadmill
1 pair of shoes for the bike
1 pair of exercise shorts for every 3 days of exercise
1 T-shirt for every 3 days of exercise
1 work shirt for every 10 days
1 T-shirt for under the workshirt for every 10 days
1 pair work pants/shorts for every 10 days
1 pair underwear for every 2 days
1 pair socks for every 2 days
2 pairs Russian overalls (optional)
They also need a spacesuit for working outside the spacecraft.
Why We Can't Go To Mars As is
If the temperature on a planet is too low, it causes chemicals to react slowly, which interfere with reactions necessary for life.
The range of temperatures just right for humans is 5 degrees Fahrenheit- 131 degrees Fahrenheit.
If the temperature is too high on a planet, molecules and genetic material start breaking down.
It is okay to have too much water on a planet as long as it is not so toxic that it interferes with the chemistry of life.
Water is important because life can go dormant between wet periods, but eventually, water should be available. We NEED water to live!
If we don't have enough of an atmosphere, gas molecules escape to space leaving the planet or moon without an insulating shield.
A perfect atmosphere is as follows:
~About 100 miles thick
~Keeps surface warm
~Protects from radiation
~Protects from small to medium sized meteorites
It is bad to have too thick of an atmosphere because the surface would be too hot for life. For example, Venus' atmosphere is about 100 times thicker than Earth's and made almost entirely of greenhouse gases. Because of this, Venus' average temperature is 864 degrees Fahrenheit - too hot for life.
~ Due to the Solar System attributes we are forbidden to sell carbonated beverages which would become a foamy mess during space travel.
