Space Flashcards
Geostationary satellite
Period - 24 hours
Altitude - 36000 km
Period of a satellite in a high altitude
Orbit is greater than the period of a sattalite lower a Lowe altitude orbit
Planet
Astronomical boys orbiting a star
Dwarf planet
Object less massive than a planet, in orbit around a star
Moon
A natural satellite which orbits planets
Sun
Star at the centre of the solar system
Asteroid
Astronomical objects that orbits the sun
Solar system
A star and all the objects orbiting around it
Exoplanet
Planet orbiting a star other than the sun
Galaxy
Gravitationally bound system of stars
Universe
All of spaceand time and it’s contents
Satellite
Weather forecasting- used to monitor the weather and climate of earth
Communications - amplify radio telecommunication signals
Scientific discovery and space exploration - used for scientific discovery and space exploration
GPS - space based radio-navigation system
Challenges of space travel - ion drive
Travelling large distance
Ions leave the drive as an ion beam, so producing thrust.
Produces small unbalanced force
Over long period of time craft will attain high velocity
Catapults and slingshots
To attain speed and direction
Uses gravity from planet, moon, or asteroid to assist space craft
Zero friction evironments
manovering in space, which is a zero friction environment, is challenging due to there being no resistive forces
