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! smile.gif

It's odd to think that from 'aboe' - MRO's burn which actually increase it's speed - but because it will being 'run over' by mars, it will be slowing down w.r.t. Mars itself smile.gif

I hope they release the op-nav imagery - I'm sure it wont be particularly great, but it will make an interesting little movie watchign Phobos and Deimos doing their thing smile.gif

How many pixels would HiRise get across the disc of Mars now?

HiRISE has an IFOV of 1 microradian, so the pixel scale is the distance times 1e-6.
MRO is probably about 7 million km out right now (the simulations on the MRO site don't show the range) so that's 7 km/pixel. Mars is about 7000 km in diameter, so that's about 1000 pixels.

Of course, there are no plans to take such images that I'm aware of. The opnav camera is pointed in a direction almost 180 degrees away from the rest of the science instruments.
