Suppose a satellite has an orbiting altitude of 1,000 km. The velocity of the satellite to maintain orbit must be about...
6,000 m/s
7,000 m/s
8,000 m/s
9,000 m/s

Multiple Choice
The LAGEOS satellite was deployed to actually track plate tectonic movement. The satellite (actually there are two) orbit at 2,000 km. What is the value of gravity at this altitude?
4.8 m/s2
5.8 m/s2
6.0 m/s2
5.5 m/s2

Multiple Choice
The relationship between satellite altitude and speed to maintain orbit is...
Directly Related
Inversely Related
9
Satellite Altitude to Orbit velocity is inversely related.
As altitude increases, the obit speed required decreasers. (This is due to lower gravity).

However...Desserts (not deserts) may seem to attract people to them, ha!
Desert = Dry arid area.
Dessert = Sweet Treats often served after a meal.
