  In order to make a soft landing, Mission Control sends it a signal to fire a short burst of its retro rockets to change its speed to one that will put the satellite in an elliptical orbit with a periapsis (the distance of closest approach, as measured from the center of the asteroid) equal to the radius of the asteroid. What is the speed of the satellite when it reaches the surface of the asteroid? G = 6.67 x 10-11 Nm2/kg2. A) 4.32 m/s
  B) 6.11 m/s
  C) 7.18 m/s
