A rocket failed to put a satellite into MEO circular orbit (18,000km altitude). Instead it ended in an elliptical orbit with a perigee altitude of 1500km and an e= 0.66667. a. Draw the intended and failed orbits. b. Calculate the Av for a single maneuver to change the elliptical orbit into the circular. Include: İ. Identify in your drawing from (a) where the Av takes place ii. magnitude and direction of the Av [Partial answer: Av = 2.8614 km/s] iii. the change in the flight-path angle Ay [Answer: 67.910°] c. Calculate the Hohmann transfer & compare total Av's (magnitudes). Identify the Hohmann transfer in your drawing. [Partial answers: AV Tot = 1.6553 km/s or AV Tot = 3.3686 km/s]
