NASA Rover Part 2
Transcript of NASA Rover Part 2
Alex Pipinos, Nawel Hamroun, & Ryan Walsh
Step 2: Brainstorm/Generate Ideas
Step 3: Research (Mercury)
Step 4: Identify Criteria/Constraints
Step 5: Consider Alternatives/Select an Approach
- Research and gain information about other planets in our solar system.
•Computer System: which would control the rover and process information
•Radioisotope Power System: A system that would convert plutonium decay into electricity to over the rover.
•Parachute: Insures that the rover lands safely and does not break from impact.
•Aeroshell: Protects the rover from the atmosphere and prevents the rover from becoming damaged.
•Camera: It is important to have cameras on the rover to see what is on the planet and where it goes.
•By visiting Mercury we can gain information of what the terrain is like and see if there are any important resources Mercury may hold.
•We can also find out the structure of the core, what the magnetic field is like, and materials at the poles.
•Mercury is approximately 77.3 million km from Earth.
•Mercury can reach a temperature of 801 degrees fahrenheit.
•At night Mercury can plummet to -279 degrees fahrenheit because there is no atmosphere to trap the heat.
•The gravity on Mercury is 3.7 m/s squared (38% of man’s gravity on earth).
•Mercury has no atmosphere, but Mercury contains a thin exosphere that is made of atoms that are blasted off the surface from solar wind and micrometeoroids.
•Some potential dangers are that meteorites do not burn up, instead they hit the planet leaving craters and, the extreme temperatures present a danger to the things that are on the planet.
•the liquid core occupies 42% of the planets volume
•Heavily cratered like moon.
•Mercury is the second most dense planet in the solar system.
•Mercury has an overwhelming amount of iron.
Step 3: Research (Venus)
•Described as a “Hot, hellish and volcanic planet”
•Venus is often called earth's twin because it is similar in size, density, composition, and gravity.
•The planet has is rich in metal and natural resources
•At closest, Venus and Earth are about 42 million kilometers apart and at furthest, they are about 258 million kilometers apart.
•The gravity on Venus is 8.87 m/s squared, in simpler terms, it is 90 percent of the gravity on earth. someone who weighs 100 pounds here would weigh 90 pounds on Venus.
•The atmosphere of mars is about 96 percent carbon dioxide, and most of the remaining four percent is mostly nitrogen. Also, the planet's temperature is about 465 degrees celsius and the air pressure there is 90 times more than the air pressure of earth.
•This planet can be dangerous for humans because the temperature of the planet is too hot to sustain human life and the air pressure is much too high. In addition, the planet does not have enough CO2 to sustain human life.
Step 3: Research (Neptune)
•Due to the little sunlight that the planet receives, there are large amounts of ice, and a slushy fluid mix of water
• This planet has some of the most violent weather, in which includes winds of up to 1,500 mph
•These powerful winds create large storms that constantly circle the planet (these storms do not last as long as the ones on Jupiter)
•Neptune is 4..4 billion km away from Earth
•36.6 ft gravity
•Neptune is blue because of the methane on the planet, it absorbs the red light and reflects blue colors
•temperatures can go down to -217 degrees Celsius
•Planet's mass of 102,410,000,000,000,000 billion
•Only 18 hours to make a full rotation
•Made of layers of hydrogen, helium, and methane
•Great Dark Spot was the largest storm recorded on Neptune, it lasted 5 years
1: The rover must have and mechanism to collect samples and analyze them.
2: The rover must be able to withstand extreme temperatures.
3. Must include a camera
- We chose Venus because it is rich in natural resources and metals, while the other planets (Neptune and Mercury) have little to no resources.
Components of the Rover
- Will allow the rover to land safetly onto the Venus ground
- Provide 'voice' and 'ears' for the rover
- Protection for the Rover
- Will allow the rover to have the ability to pick up and put down objects
Cameras (Front and Back)
- Provide the ability to see the front and backside of where the rover is
