What a great achievement!!!
First historic pic from orbit - and since I always love to experiment and bring out as much detail as possible in photos just for my own interest - I did a false colour (+ a few other things) version during lunch which seemed worth posting. So here it is!! Haven't been here for a while but good to see everyone's passion and skills again :-) Hi res 6 mb!! version at https://picasaweb.google.com/10220631534056...730326334840018

There's a link to the teleconference on this page now:

No raw images for this mission, but their first delivery to the PDS will be just 6 months after orbit insertion, probably including 2 months worth of data.

First color image released:

I've actually been wondering, are the filters on the WAC as narrow as the graph below portrays? If so, how close to 'natural' is actually possible for the images?

I see no reason why the chart would be wrong. The aim is not to take 'natural' color photographs. The aim is to do science. Much like with MER and other spacecraft, you take those science filters and approximate a true color view using algorithms.

I believe it's enhanced with the IR filters to bring out the blue/yellow shades. So, I don't believe it's what your eye would see if you were in MESSENGER's position. Still a nice pic though! |

It is what you might see if your eyes were properly designed to study the surface composition of Mercury.

Because Mercury's visible spectrum is pretty bland, I expect that using images from these narrowband filters to determine true color shouldn't be much harder than it would be for broadband filters.

@ Phil: There's a lot going on in that image. Is that an ancient lava 'riverbed'? Also, what's with the linear streaking in that vicinity.
Oh, this is gonna be a fun mission!!!!

Check the Wikipedia front page (April 1st).
Nice tribute in the news section. -------------------- To a body of infinite size there can be ascribed neither centre nor boundary... Thus the Earth no more than any other world is at the centre. -Giordano Bruno, 1584.
