What sort of lifetime would you expect for a satellite (circular orbit) at 150 km? What is the maximum height for a long-lived atmospheric monitoring balloon?
Lifetime of a satellite at 150 km will be very less as it lies in the Thermosphere and the temperature is too high for the satellite to survive.
Maximum height for a long lived atmospheric monitoring balloon is 90,000 feet i.e. 27.3 km.

A satellite is to be placed in a circular orbit 10 km above the surface of the moon (Rm = 1.74 * 10^3 km, Mm = 7.35*10^22 kg). 1. What is the orbital speed and period of the satellite? 2. If we could place a satellite in orbit just inches from the Earth's surface, what would its orbital velocity and period be? (Re = 6.37 * 10^3 km and Me = 5.972 * 10^24 kg)
A satellite of mass m (where m ≪ Me) is initially in a circular orbit around the Earth at a height of 410 km above the Earth’s equator. Its operators would like to move it into a geosynchronous orbit using a Hohmann transfer orbit. Assume a spherical Earth with radius 6371 km. (a) Sketch the satellite’s Hohmann transfer orbit. (b) Find the satellite’s initial (circular) orbital speed according to an inertial observer. (c) Find the maximum height of the satellite...

12.104. A satellite describes a circular orbit at an altitude of 19 110 km above the surface of the earth. Determine (a) the increase in speed required at point A for the satellite to achieve the escape velocity and enter a parabolic orbit, (b) the decrease in speed required at point A for the satellite to enter an elliptic orbit with a minimum altitude of 6370 km, (c) the eccentricity e of the elliptic orbit. R = 6370 km 19...
