Navigator has many good links.
So does Universe Today; it includes
current news about many aspects of space.
- The Center for Mars Exploration
with many pix and some info about past and present missions. Note that
"Mars Images and Meteorology" points to a page with gigantic images, sizes
not given. The "Viking Orbiter Image Archive" starts with a giant picture
but then issues small ones at high res ( < 400 m/pxl). "Other Images" has
some pretty ones, as does "Surface Images". Under "Mars Tools", look for:
- Mars Multi-Scale
Map by Calvin Hamilton and friends at Los Alamos. Images take a minute
or more at 28.8; it reverts to 512x512 even when you select 256x256, and uses
more than 200 grey levels. But see also Kanef's
Atlas of Mars where you
can get images as small as 100k, displayed in 3x3 tiles, using only 16
grey levels, from the
- Clementine moon pix. Some of
the GIFs are gigantic; preview sizes of the
The image browser is neat
and sends images as small as 60k bytes (if you choose 256x256 pixels).
- Seeing the Earth in 3D Through Imaging
- Earth from space;
you specify lat & long. Generated image can be sizable, but even so, pixel
size is in the tens of miles, I think. So use Google Earth instead.
Launchers and propulsion
Some of these links may be out of date. A good summary of the more
promising launcher development efforts going on these days is to be
found at Space Future, with
links to the sites of the companies doing the work. See also
HobbySpace and my own
notes from the Space Access '05
I also have a list of pressure groups who
are trying to get access to space at reasonable prices (no, not by
asking the government to absorb 90% of the cost!), startup companies,
and the like. It overlaps with what's on this page. Sorry.
- The good guys: Space Access
- Some pretty good guys: the X-Prize
- The not-so-good guys: NASA's Exploration Division incl "Beyond LEO"
newsletter with some pretty good articles
- The optimists: InterGlobal Space Lines
- Some other guys: I used to have a link here to the Artemis Society, but they
didn't like the way I described them. Rather than risk a lawsuit, I removed it,
because I'm certainly not going to let them dictate what I say here.
