In aerobraking, since the farther it gets into a/b STAGE, the faster the orbit, is that because the orbits get faster the lower it gets than the rate at which it slows down???
Joshua Cranbrook Middle School Bloomfield Hills, MI ANSWER: Hi Joshua, You’re absolutely right; the atmospheric drag component (the friction the spacecraft experiences as it passes through the top layer of the atmosphere) is a much smaller factor in changing the spacecraft’s speed, then the change that occurs because of the change in orbit. Odyssey right now is in an approximate 18-hour egg-shaped orbit, once mapping starts (hopefully some time late January) we will be in a circular orbit that will take only 2 hours to circle the planet at a height of 400 kilometers (250-miles) above the surface.
