The apoapsis altitude (highest point in orbit) dropped from about 6050 to about 4570 km, an orbit change that improves MAVEN's availability to support relay communications with NASA's landers and rovers on the surface of Mars.
A deep-space maneuver is performed near the apoapsis in order to modify [v.sub.[infinity]] (increase, if one is considering an escape trajectory, or decrease, if one instead considers a capture) at the next encounter of the probe with the secondary body.
The Spacecraft is now circling Mars in an orbit whose nearest point to Mars (periapsis) is at 421.7 km and farthest point (apoapsis) at 76,993.6 km.
With this aim, we know that a bad distribution of the points in the periapsis and the apoapsis leads inexorably to truncation errors of such magnitude that make impossible the task proposed regarding the reduction of errors.
