Unformatted text preview: v TOTAL = |∆ v 1 | + |∆ v 2 | ) b. Calculate the time required for the transfer (in days). 2. (15 points) A s/c is presently orbiting Earth on a path with a 1 = 15000 km, and e 1 = 0.45. a. Calculate the flight-path angle when the s/c reaches a true anomaly of 258 o . b. Calculate the ∆ v needed to circularize the orbit at θ 1 = 258 o . where the radius is r 1 (that is, to execute an impulsive maneuver onto a circular orbit with radius r 1 ). c. Calculate the ∆ v needed to circularize the orbit at perigee on the original orbit....
