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.

Planetary motion. A planet or asteroid orbits the Sun in an elliptical path'. The diagram shows two points of interest: point P, the perihelion, where the planet is nearest to the Sun, and the far point, or aphelion, at point A. At these two points (and only these two points), the velocity v of the planet is perpendicular to the corresponding "radius" vector ỉ, from the Sun to the planet. An arbitrary point Q is also shown. P A TP A Suppose the asteroid's speed at aphelion is vA = 900 m/s, and it's distance from the sun there is ra = 35 AU (AU is the "astronomical unit", commonly used in planetary astronomy). a) Determine the planet's speed vp at perihelion. b) Determine the planet's distance rp from the Sun (in AU) at perihelion.
