The Clementine project was a very successful experiment in ``cheap & light'' space hardware; even though it did die somewhat early, it managed to map the moon's surface quite thoroughly.
(17.05.95) I heard that communication with Clementine has been re-established; maybe it's even possible to slow down the rotation. Still, I don't think much useful (beside technology data) will come from it.
The Space Science and Engineering Center at the University of Wisconsin - Madison is pleased to announce the availability of realtime color global composites on our WWW, gopher and ftp servers. The images are a combination of clouds, sea surface temperature and observed land temperature. The images can be found at:

This is a Mollweide projection composite image of cloud top, synoptic observation and sea surface temperatures. The cloud image is a combination of GMS, GOES-7 and Meteosat imagery. A grid of temperatures from synoptic observations, available every 6 hours, is made into an image and merged with an image of SSTs (generated from a daily SST grid from NMC).
An algorithm was created to compare the surface temperature (either SST over water or synoptic observation temperature over land masses) with the IR temperatures from the satellite imagery. Using this algorithm, the composite image uses the cloud values if an IR temperatures is more than 14 degrees K colder than the surface temperature. This algorithm improves cloud/no-cloud classification by including marine stratus and filtering out clear regions that are very cold (i.e., polar regions).
A description of the Pioneer Venus missions.
The Pioneer Project now has its own WWW home page. Details on the status of the Pioneer 10/11 probes are provided, including some images.
The latest Hubble Space Telescope image of Jupiter has been released today. The image is available at either the JPL Comet Shoemaker Levy Home Page or the STSCI home page or ftp site:

(23.05.95) DC-X Test Site, White Sands Missile Range, New Mexico -- The DC-X reusable rocket low-altitude operations testbed took off under cloudy skies on its sixth flight this morning at 9:40 MDT. The test mission lasted just over 123 seconds, beginning with a slanted ascent to 4350 feet and 1150 feet downrange, continuing with a horizontal translation to directly over the landing pad (350 feet from the launch stand), and finishing with a vertical descent to a normal landing.
In particular, the Space Access Society area has the entire history; there is also information to be found under the Launch pages and the Policy pages.
If you are looking for picture and some of the MacDac documentation, you can find pointers to some ftp sites via the Space Index at this site.
For the person who asked about Black Horse - you will find a limited amount of Black Horse information, including a technical paper, in the Launch section.
As I said before, I requiest that people *not* use the site Monday Wednesday Friday afternoon's before 18:00 GMT.
I am please to announce the completion of The Space Shuttle Clickable Map. When accessed, the viewer will be able to learn more about each component of the Space Shuttle, as well as general information on the space program, links to other space resources, and an overview of the shuttle processing through text and images.
In addition, you can access the map from a link off the Student Space Action homepage as well as through the students page and the online research page of the Aerospace Virtual Library.
All questions and comments regarding this project can be sent to me.

The Planetary Data System Imaging Node now has a home page available on the World Wide Web. The URL is:
http://cdwings.jpl.nasa.gov/PDS/
This home page was created by the US Geological Survey in Flagstaff, Arizona, and the Jet Propulsion Laboratory in Pasadena, California. The PDS Imaging Node is the curator of NASA's primary digital image collections from past, present, and future planetary missions. The Node now has image browsers for the online Venus Magellan and Mars Viking Lander image datasets, and will be providing browsers for other missions in the future.
This Space Calendar covers space-related activities and anniversaries for the upcoming year. The latest copy of the calendar is available using anonymous ftp to explorer.arc.nasa.gov as pub/SPACE/FAQ/space.calendar. It is also available on the World Wide Web at
http://newproducts.jpl.nasa.gov/calendar/
The WWW version of the calendar includes links to other home pages that have additional information on that subject.
This Calendar is compiled and maintained by Ron Baalke. Please send any updates or corrections to baalke@kelvin.jpl.nasa.gov. Note that launch dates are subject to change. Also, anniversary dates are listed in 5 year increments only.
I still search for a better online nuclide chart. All element tables just provide the usual mixes and averages. An online chemical handbook (you know, "melting point, solubility, toxidity, percentag in earth crust, common compounds") would also be nice.
Physics Servers and Services Around the World
The 1986 CODATA Recommended Values of the Fundamental Physical Constants are not terribly well-marked up. Instead of one large text table, there are many different inline GIFS (probably needed so that the usual symbols can be shown). No cut/past of numbers, no easy searching.
One of the many Web Elements incarnations.
A Nuclide Table. Nice graphical interface, but somewhat off-putting for a colour-challenged user like me (decay times are colour-coded). You also see that the table code is originally written by a Korean -- "The plutonium is artificial element !" is distinctly far-east sounding. Also a very interesting touch: "To know the source of individual nuclide data, use View Source menu of the Web browser." yep, the citation is a one-line comment early in the body.
Laws, Rules, Principles, Effects, Paradoxes, Limits, Constants, Experiments, & Thought-Experiments in Physics is one huge 60k page containing both well-known items, many things I've never heard of before, and a few items i didn't expect (e.g. the antrophic principle).
