I have access to a 300 dpi digital color scanner and have made numerous GIF
images of Voyager photos from magazines and books. The resolution is
640x480x256; typical file size is 200K. While obviously not "raw science
data" I suppose they might be interesting to manipulate digitally.
They typically come out better than the frame-grabbed images I've seen.
I'd like to offer them to anyone interested, but having no access to an ftp
site, I can't put them in a place where they can conveniently be retrieved.
If anyone with ftp access would volunteer, I could mail them the floppies
(what a network!) and they could upload them to the ftp site.
Also, I would like to know if there is a good source for Voyager photographs.
Magazine photos digitize on my scanner pretty well if they are 1/2 page
or larger, but with smaller photos I start seeing evidence of the four-color
printing process when the image is blown up. I'd love to get 8x11 or larger
glossies.
Thanks,

They wouldn't be evenly distributed, would they? I'd expect
clustering in launch facilties [Mid-Florida, Northern South America,
a couple of sites in Asia] just to avoid needless duplication of
launch resources. Mind you, most launch sites are as close to the equator
as convinient, and the ozone munching processes seem to run with
maximum efficiency at the poles [Of course, CFCs seem to got the
problem of getting to the poles solved, and they get used mostly in
temperate countries].
If there *is* an upper limit to tolerable launch rates, it will
be interesting to see how launches get allocated. Is there an
obvious international authority for this kind of thing [and does
