Describe the two Martian polar caps, their seasonal and permanent composition, and thedifferences between them?
1. (a) Calculate thermal escape times for H,
He, and H2O on Mars with exosphere
temperatures of 210 K and 1000 K.
Comment on the volatile history on Mars if
transient events ever heated its exosphere
to 1,000 K for 1 My (b)Why is the calculation
inadequate to fully explain the escape of
Martian volatiles?
The average distance from Earth to Mars is 1.5 AU. If you send a command using radio waves (a form of light!) to a rover on the Mars surface, how long will you have to wait before you receive the response? Assume the rover responds immediately after it receives the command
