Problem 1 A probe in a "parking orbit" around Mars has a pericenter of 4000 km and a velocity at pericenter (relative to Mars) of 4.165 km/sec' The probe is commanded to transfer into another orbit by making a burn 10 minutes after passing pericenter. 1' (10 points) What is the mean anomaly at the time of the burn? Express your answer in radians to three significant digits. 2' (15 poi,nts) What is the eccentric anomaly at the time of the burn? Express your answer in radians to three significant digits. Note: If you need to solve Kepler's "qrrutiorr, solve it via the Newton-Raphson method. Set the problem up and solve for the first iteration only, assumingan initial guess of Eo : M. 3' (5 poi,nts) What is the true anomaly at the time of the burn, assuming the eccentric anomaly calculated above? Express your answer in radians to three significant digits.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
