A crew Capsule is returning from the ISS, whose orbit is circular with radius Ro + 400 km. Prior to re-entry, the capsule will insert into a 200 km Coplanar parking orbit to validate a new safety. system. The crew execute a Hohmann transfer to change their orbit from that of the iss to that of the parking orbit. Compute the phase angle o at the time of Impulse 1. State answer in degrees.
