Satellite

Satellite: an object which orbits planets or stars

Types of satellite orbits

Types of Satellite Orbits

Orbit shapes

Circular
Elliptical

Specific positions of satellites in the orbits

Apogee
Perigee

Relationship between orbital height and satellite velocity

The higher the orbital height of a satellite, the lower the satellite speed for it to remain in orbit
This is because the gravitational force on a satellite decreases when the orbital height of the satellite increases

Methods of sending launch vehicles into orbit

Launch vehicles: used to send satellites or spacecraft into outer space
- Expendable launch vehicle (ELV)
- Reusable launch vehicle (RLV)
Ways to send launch vehicles into orbit:
- Directly into orbit
- Hohmann transfer orbit

Zero gravity

The condition when no significant gravitational force effect is felt

Impact of rapid development in space technology

Increased waste in space / space junk
Increase in research and development activities
