A crew capsule is returning from the ISS, whose orbit is circular with radius Re + 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 eccentricity of the transfer are. Take M= 398400 km²³s-² and R = 6378 km
