Scientists want to place a 4100.0 kg satellite in orbit around Mars. They plan to have the satellite orbit a distance equal to 1.5 times the radius of Mars above the surface of the planet. Here is some information that will help solve this problem:
mmars = 6.4191 x 1023 kg
rmars = 3.397 x 106 m
G = 6.67428 x 10-11 N-m2/kg2
What speed should the satellite have to be in a perfectly circular orbit?

Traditionally, the atmosphere has been referred to in 4 layers, tropo, strato, meso and thermo w/ ionto and exo being considered part of thermo. Now I see the exosphere being referred to as its own distinct layer, which is most correct? when did this paradigm shift take place? Thanks
