Andrew asked:
If you had access to the Hubble Space Telescope, which has an angular resolution of 0.1 arcsec. What is the size (in kilometers) of the smallest feature you could have seen on the Martian surface during the 2005 opposition, when Mars was 0.464 AU from Earth?

These are the actual photos from that time.
Mars was 20.19 arc seconds around that time and is 6792 km wide.
6792/20.19=336.4 km/arc second. 1/10 of that is 33.64 km sageofstars
