The mercury maps are astonishing at this stage in the game! Terrific effort!
Can you post the link to the 8" amateur images? -------------------- Remember: Time Flies like the wind - but Fruit Flies like bananas!

These are great images obtained from the ground. However, why couldn't the Hubble Space Telescope be used to image the non-Mariner side of Mercury? Hubble has resolved details on some of Juptier's moons (about the same size as Mercury) and Mercury is far closer to us.

iirc - Hubble has a minimum sun angle which is can NOT go over - I dont think it's ever imaged Mercury simply because it's too close to the sun - and the damage that could be done is huge.

I wonder if the concern is the actual damage if Hubble observed Mercury, or the potential damage if Hubble accidently pointed directly at the Sun as it slewed to obseve Mercury.
The difference is that if Hubble will not be saved and it will be de-orbited, might it be worth the risk to have it obseve Mercury as it's last obsevation? |

A 'family portrait' of the Solar System by HST as it nears the end of it's operational lifetime would be very attractive, and a fitting companion to the Voyager 'Pale Blue Dot' sequence of images. Perhaps it could be justified as an engineering test, establishing a common baseline for all the available bodies it can see - not to mention a powerful bit of PR!

Here's one of Ksanfomality's new photos of Mercury.

I believe that 'Sky and Telescope' published a new mosaic of Mercury about 2 years ago, utilizing Mariner 10 images. It shows the entire hemisphere of Mercury imaged by Mariner 10 and was created by Mark Robinson of Northwestern, I believe. However, can any one find that image on the Internet? I'm sorry, but I do not recall which issue of 'Sky and Telescope' included that mosiac. Another Phil |
