Planned for 2.6 days before landing, the TCM-5 maneuver would have served a different purpose than the other TCM's. It was essentially an insurance policy for the orbiter. In case the orbiter came too close to Mars upon arrival, TCM-5 would have been used to increase the orbiter's altitude for the Mars orbit insertion burn. The TCM-5 commands would have been stored on board the orbiter several days in advance. The orbiter had two burn opportunities -- at 24 hours and at 12 hours before the Mars orbit insertion burn. During the last day before arrival, navigators determined the orbiter was not too close to Mars. Because the orbiter arrived at Mars on the expected trajectory, TCM-5 was never needed.
