MRO has shifted from the cruise phase to Approach phase. Apparently, the trajectory is so good that TCM-3 was cancelled. This is good news for the prospects for a long life for MRO supporting future missions. TCM-4 is on Feb 28, and MOI on March 10. Only 5 weeks away!

Good news. I seems that MRO has started to gain its speed due to Mars gravity tug, has not?
What is MOI? Mars Orbit Insertion. http://mars.jpl.nasa.gov/mro/gallery/cruis...oach_200602.jpg "It was a very busy time for the team. Many tests were conducted to ensure that the instruments onboard were functioning properly and our navigators performed trajectory correction maneuvers to keep us on a very precise path to Mars." Speaking of that precision, the third of four possible course corrections was deemed unnecessary this week. "The navigation solutions have shown a great consistency since the second trajectory correction maneuver was executed on November 18," said Han You, navigation team chief. "More importantly, the current data indicate that the spacecraft aim for insertion into Mars' orbit is well within the projected target. If the current trend continues, the spacecraft will require only a very small nudge to fine tune the final aim." Rodolfo |
