A spacecraft is in an elliptical orbit around the Earth with a = 1.8 x 107 m and e = 0.4. (a) How much time is required for the spacecraft to travel from u = 30 deg to v = 185 deg, in hours? (b) What will the true anomaly angle be I hour after the spacecraft passes through periapsis, in deg? A spacecraft is in an elliptical orbit around the Earth with a = 1.8 x 107 m and e = 0.4.
