Determine an interplanetary Earth-Jupiter mission that uses a heliocentric Hoh- mann transfer. Assume coplanar concentric planetary orbits using the data in Table 10.3. Determine the following parameters: a) Hyperbolic departure velocity, v in km/s b) Hyperbolic arrival velocity, v in km/s c) Hohmann-transfer flight time in days d) Phase angle at departure e) Departure date for first launch opportunity after January 1, 2020.
