Space Systems Engineering IHW #31.NASA wants to move a malfunctioning spacecraft from a circular orbit at 500km altitude to oneat 150km altitude, so a Shuttle crew can repair it.a.What is the energy of the transfer orbit?b.What is the velocity change (!V1) needed to go from the initial circular orbit into thetransfer orbit?c.What is the velocity change (!V2) needed to go from the transfer orbit to the finalcircular orbit?d.What is the time (TOF) required for the transfer?2.A new research spacecraft is designed to measure the environment in the tail of Earth’smagnetic field. It’s in a circular parking orbit with a radius of 12,756 km. What
