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!

The MRO spacecraft will remain out of contact for a half hour. Lots of time of suspense. There will be a TV NASA coverage during this MOI?
The 109 km, I think it is the outside of ending of Martian atmosphere. Isn't it? Rodolfo |

The 109 km, I think it is the outside of ending of Martian atmosphere. Isn't it? Rodolfo Rodilfo: Not at all. Relatively speaking, the upper atmosphere of Mars extends *further* from the planet than does that of the Earth, and the pressure drops more slowly. So 109 km is well within the (very thin) upper atmosphere. Mars is particularly good for aerobraking, having a thin but extensive atmosphere which should be more forgiving than our own. But, after MCO and Mars Observer, there will be a certain tension in the (rarefied) air!. Fingers, and all other appendages should be tightly crossed, chickens should be broken down into component parts, and any spare virgins kept neatly wrapped but ready for sacrifice - it's scawwwwwwy!
