Interesting new image of the Arsia Mons pit. The polar pit gullies image is pretty good, too. |

Recon sats can look at targets at way off verticle slant angles. An infamous pair <near vertical and 45'ish deg slant angle> of recon sat images leaked about or a little before 1990 of a Soviet shipyard (the leaker was imprisoned for it) show good slant angle capability.
The basic fact is that recon sats have had hubble size mirrors, basically. An Aries-5 could or Saturn 5 could have launched much bigger optics. You can play with clean, oversampled high signal to noise ratio diffraction-limited images to extract about 2 times the apparent raw resolution out of the data, but that's about it. |
