I don't know if it is the same thing, but I just bought from NSSDC a CD-ROM with several astronomical catalogs, tables, maps and planetary images. The disk was produced by JPL and is called the Interactive Data Interchange (IDI) 1986 Science Sampler Disk. Apparently it is a grab-bag of files collected during a workshop whose primary goal was to test the feasibility of exchanging and collecting space data via computer networks. The files that made their way into the IDI disk are a quite mixed lot. Many of the files are random samples of larger data sets that hopefully one day will be published on their own. The data on the disk (some 600 Megabytes) includes, among other things * some star catalogs. * the IRAS (Infra-Red Astronomy Satellite) point source catalog. * a few radar and landsat(?) images of the Earth. * altitude maps (artificial images where brighter = higher) of the continental US, almost complete. * some images of the oceans (temperature and clorophyll concentration). * a table of planetary features (craters, mountains, etc) with names and locations. * miscellaneous Halley Watch observations for comet Crommelin. * some geological maps and miscellaneous data for Mars. * a dozen images of Phobos (Viking? Mariner?). * a couple hundred Voyager images of Jupiter, Saturn, and their satellites. So far I have only had time to browse through the Voyager images. Note that these are RAW images, with all the pixel defects, registration marks, missing scanlines, exposure errors, and so forth. They are *monochrome* images (taken through several filters, though), with 800x800 pixels at 8-bits per pixel. (That is about 650KBytes per image, so don't ask me to post them to the net!) Whether you will find them exciting or boring will depend on how interested you are in planetary exploration: their visual impact is is not great, but the resolution is the best you can get on this planet. Obviously, you need access to a computer with a greyscale display and a CD-ROM drive to make use of this disk. It won't play on a Videodisc player... Bundled with the CDROM comes a floppy disk with IMDISP, an Image Display Program written by JPL that runs on MS-DOS PC's with VGA/EGA/PGA/CGA cards. The package also includes a 60-page manual for IMDISP and the IDI CD-ROM. All this for $50 (Well worth it, IMHO). It seems that JPL is preparing a (multi-volume?) CD-ROM with all Voyager images taken during the Uranus encounter, which eventually will be available through NSSDC.

RELEASE: 89-32 NASA AND JAPAN SIGN SPACE STATION MEMORANDUM OF UNDERSTANDING NASA Administrator Dr. James C. Fletcher and the Ambassador of Japan to the United States H. E. Nobuo Matsunaga today signed the memorandum of understanding (MOU) between the U.S. National Aeronautics and Space Administration and the government of Japan on cooperation in the detailed design, development, operation and utilization of the permanently-inhabited, civil space station, which the U.S. calls Freedom. The agreement was signed at a brief ceremony at NASA Headquarters, Washington, D.C. Comparable MOUs with the European Space Agency and Canada were signed, along with an inter-governmental agreement, in a ceremony held at the U.S. State Department last September. The MOUs signed between NASA and its three partners focus on programmatic and technical aspects of the cooperative effort and establish the management mechanisms necessary to carry out the Freedom program. The MOU with Japan will enter into force upon written notification by each party that all procedures necessary for its entry into force have been completed. Until then, Japan will continue to work under an extension of the MOU signed with NASA in May 1985 at the start of the space station program's definition and preliminary design phase. Under the agreements, Japan will provide the Japanese Experiment Module (JEM) to the Freedom program. The JEM, to be permanently attached to the space station base, consists of a pressurized laboratory module, at least two experiment logistics modules and an exposed facility, which will allow experiments to be exposed to the space environment. Experimenters will conduct materials processing and life sciences research in the laboratory module, while the logistics module can be used to ferry materials between the station and Earth and for storing experimental specimens and various gases and consumables. Space Station Freedom is an international space complex comprising a permanently-inhabited base and unmanned scientific platforms to be placed into orbit in the mid 1990's. The mission of the Freedom program is to provide for the United States and its international partners -- Canada, Japan and 9 European nations -- a diverse set of capabilities permitting humans to live and work in space for extended periods of time. The station will enable fundamental research in materials and life sciences, support observations of the Earth, its solar system and the universe and provide the on-orbit test bed for the development of advanced technologies necessary for human exploration of the solar system. ------------------------------ Date: 15 Mar 89 18:03:55 GMT From: csd4!mcp2@csd4.milw.wisc.edu (Michael C Polinske) Subject: Re: Moronic TV news coverage In article <518@gandalf.littlei.UUCP> tim@opoxsrv.i.intel.com.ogc.edu writes: In Portland, OR (Rogers Cable TV) there were two channels that had pure NASA feeds (NASA Select?). These were a local cable access channel and (more importantly) CSPAN-II, one of the congressional channels. I know that the local channel was set to start the NASA feeds at 12:30 am pacific time. I don't know when CSPAN-II started their coverage, but there was NO ancher person overdubbing, other than the official NASA lady (which you would get even if you had a direct downlink from NASA Select. Check to see if your local cable has CSPAN-II (I watched it over the local channel because the local had a jumpy picture). I don't know about the lauch coverage, but I do know that a public access channel on our cable system has a continuous coverage of the shuttle mission. They have done this one time before also but I do not believe they do this for secret missions. In the corner of the screen it shows something like this: SCHOOL CABLE TV NASA [LIVE] It shows this even when I know that I saw it early. so the cable system must put it in. I was wondering what network carried such continuous, uncommentated (word?) coverage of a space flight.

It contains a interesting article part written by Sally Ride, titled 'Soviets in Space' (page 18-26). This includes a few interesting pictures including a cutaway diag. of Mir, and a large photo of a horizontal stacked Buran Shuttle on its Energia in the hanger. The articles main task is to sum-up the Soviet Space capability, and establish a clear picture of the Soviet space plan. Nothing is left to chance, with mention of nearly all Soviet rockets and Space stations capabilities and roles etc. The picture painted is a worrying one, especially when compared to the US. Also in the same volume (page 10) is a light-hearted article titled 'In Memoriam', concerning the collapse of a 300ft radio telescope in West Verginia in November'88. At risk of copyright, here is a short extract: "Birds..liked to roost in the receiver horns, far above in the dish. To avoid climbing up ...someone installed an electronic scare-crow, a tone generator that produced cosmic sounding bleeps and bloops that were audible all around the area. We would tell tourists that bleeps were signals being received from space..and the visitors went away satisfied."

The definition of the event horizon is the point at which photons cannot escape to *infinity*. This in no way implies that they cannot cross the event horizon, they just cannot make it very far past it (depending on how deep they started). The bonds between atoms (nucleons) would begin to behave *oddly* as the energy of the virtual photons (gluons) would be different as seen by the higher and the lower (gravitationally speaking) particles.
