A space probe is to be placed in a circular orbit of radius 4000 km about the planet Mars. As the probe reaches A the point of its original trajectory closest to Mars, it is inserted into a first elliptic transfer orbit by reducing its speed. This orbit brings it to Point 8 with a much reduced velocity. There the probe is inserted into a second transfer orbit by further reducing its speed. Knowing that the mass of Mars is 0.1074 times the mass of the earth, that ra 9004 km and rg 180 004 km, and that the probe approaches A on a parabolic trajectory, determine the time needed for the space probe to travel from A to Bon its first transfer orbit. Apphet Fie trr The time needed for the space probe to travel from A to Bon its first transfer orbit is
