400 km altitude with flight path angle -10.0 degrees and speed 10.8 km/sec. a. Using Kepler's equation, determine how long it will take the spacecraft to cross lunar orbit (assume the Moon is on a circular orbit about Earth with 384,000 km radius, and ignore the lunar gravitational effects). Confirm your answer to part (a) using the appropriate Lambert TOF b. A spacecraft leaving Earth is deployed at burnout from its launch vehicle at C. equation. If burnout speed is increased to 13 km/sec (still with flight path angle at -10.0 degrees and altitude 400 km), how much time can be saved for the trip to the Moon?
