Solar System
how many planets are in the solar system
8
(why) rockets have pointy tops
to reduce air resistance
true
Used to launch satellites into orbit
Rockets
(true or false) remote sensing involves physical contact with the object being observed.
false, remote sensing does not involve physical contact with the object being observed.
the order of planets in the solar system
1. mercury
2. venus
3. earth
4. mars
5. jupiter
6. saturm
7. uranus
8. neptune
(true or false) rockets take off at an angle
false, rockets take off vertically
rover are used for?
1. collecting samples
2. taking pictures
3. planetary science
two satellite components
1. antenna
2. electric power system
3. payload
4. on-board computer
5. mechanical system
6. guidance and stabilization system
7. power source
3 things that can be detected with a satellite
the hottest planet
venus
two things that rocket can carry
1. people
2. supplies
3. satellites
4. other spacecrafts
(true or false) space rovers are typically controlled by astronauts on the planet they are exploring
false, space rovers are usually controlled remotely from Earth
a load / instrument that is carried by a satellite
(can vary depending on satellite mission)
Payload
planets in the solar system with zero moons
mercury or venus
three rocket components
1. nose cone
2. payload system
3. guidance system
4. the body
5. the fins
three rover components
1. communication system "antenna"
2. navigation system "cameras"
3. electrical power system "solar panels"
4. mobility system "tires"
5. electrical power system "battery"
two main satellite types
natural and artificial
change detection can be used to detect changes caused by what natural phenomena? (give examples)
storms, earthquakes, floods, vegetation, volcanic eruptions,....
why is neptune blue
because of methane
the purpose of fins in rockets?
provide stability
example of rovers
moon rovers: Apollo Lunar Roving Vehicle and Lunokhod
mars rovers: Curiousity Rover, Opportunity Rover
three satellite applications
1. telephone
2. television
3. weather
4. navigation
5. safety
6. space science
