Mars Reconnaissance Orbiter will follow clues to where the lost Mars Polar Lander and Beagle 2 might be. |

Lunar orbiter 2 and 3 were capable of 1 meter resolution with the high resolution frames. Orbiter 1 had it's image motion compensation system fail, and the high rez pics from low orbit were smeared.
Orbiter 4 had 50 meter rez from periapsis in it's eccentric mapping orbit. Orbiter 5 was in a higher periapse orbit than 1 through 3 for science site mapping As far as resolution possible from Mars orbit... Remember a bit of physics called the "diffraction limit" Hubble-sized optics in low earth orbit have a diffraction limit of maybe 5-10 cm on vertical pointed images... Hubble sized.. that's the big recon sats. You can see a licence plate but not read it. (that's what I understand, I've never seen real performance numbers) Mars Recon orbiter's gonna be working essentially at it's diffraction limit, I hope and expect. If you want to do better, you're gonna have to buy a spare KH-11 or some such sat from the spooks. It wouldn't be easy to get it to Mars even if you had it! |

Edstrick (or anyone else for that matter), do you have any info on MRO's optics? I don't even know aperature. -------------------- |
