what geologic process could have formed the channel on mars
Part of the "Mars Direct" mission plan involves rotating the spacecraft on its way to Mars to provide the astronauts with a simulation of Martian gravity.
True
False
Due to the need to catch the correct launch window for the trip home, the total duration for a round trip to Mars will have to be
at most 18 months
at least 18 months
at least 30 months
at most 12 months
at least 24 months
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
