We are planning a human exploration mission to Mars. We will first place our spacecraft into a circular around Mars and then send down a lander.
a) If we want the spacecraft to orbit at an altitude of 170 km above the Martian surface, what will the velocity and orbital period of the spacecraft?
b) When we land astronauts on the surface of Mars, what acceleration due to gravity in terms of g’s (i.e. as a fraction of the Earth’s gravitational acceleration) will the astronauts experience? You are permitted to use an online resource (e.g. Google) to find the necessary information about Mars that you might need in solving this problem.
The asteroid 243 Ida has a mass of about 4.0×10¹⁶ kg and an average radius of about 16 km (it's not spherical, but you can assume it is).
Calculate the speed with which you would have to throw a rock to put it into orbit around the asteroid 243 Ida, near the surface.
How long would it take for your rock to return and hit you in the back of the head? (Express your answer in hours.)
