Consider an orbital transfer from a 1000 km altitude circular Earth orbit (LEO) to a 384400 km altitude circular Earth orbit (trivia: where is it going?) using: - A direct Hohmann transfer - A bi-elliptical transfer a. Draw a schematic of the 2 transfers, including the direction and approximate relative magnitude of the different Av's. b. Calculate the total Av & time for the Hohmann transfer. [Answer: 3.763 km/s, 5.130 days] c. Calculate the total Av & time for the bi-elliptical transfer with first orbit eccentricity e=0.9750. [Answer: 3.685 km/s, 28.87 days]
