Question
Plans are being made for an Earth-Saturn mission with a sunny-side (in front of) swing by Jupiter. Phase I will be an Oberth escape from the surface of the Earth, Jupiter will be a Hohmann transfer to Jupiter, and phase III will be a hyperbolic flyby of with an approach distance of 450,000 nmi. Find the heliocentric velocity and V. as the spacecraft enters the SOI of closest and the characteristics of the flyby trajectory to include the altitude of approach to Jupiter. Find the turning angle, the heliocentric velocity, and the heliocentric elevation as the spacecraft leaves the Jupiter Draw the vector diagram representing the turning of V. Describe the modified heliocentric trajectory. If so, what will v. the intersection angle (heliocentric elevation angle) be? What is the velocity budget for phases through III?Explanation / Answer
a)The heliocentric velocity will be definitely equal to 8m/s as it is a type of direct escape from earth(time taken by sunlight to reach earth).
b)The turning angle will approximately be equal to 90degree and the heliocentric velocity will be less than 8m/s as now it comes from the surfac of Jupiter.
c)The modified heliocentric trajectory is nothing but here the velocity to reach a destiny will be less than 8m/s.
d)Definitely it will reach the orbit of saturn,and at that time the interception angle will be slightly less than 90degree.
e)Velocity budget is as usual equal to 8m/s for both phases 1and lll
