This paper describes web based simulation of Shuttle launch operations <strong>and</strong> debris dispersion. Java 3D graphics provides<br />
geometric <strong>and</strong> visual content with suitable mathematical model <strong>and</strong> behaviors of Shuttle launch. Because the model is so<br />
heterogeneous <strong>and</strong> interrelated with various factors, 3D graphics combined with physical models provides mechanisms to<br />
underst<strong>and</strong> the complexity of launch <strong>and</strong> range operations. The main focus in the modeling <strong>and</strong> simulation covers orbital<br />
dynamics <strong>and</strong> range safety. Range safety areas include destruct limit lines, telemetry <strong>and</strong> tracking <strong>and</strong> population risk near<br />
range. If there is an explosion of Shuttle during launch, debris dispersion is explained. The shuttle launch <strong>and</strong> range operations<br />
in this paper are discussed based on the operations from Kennedy Space Center, Florida, USA.<br />

Software for Viewing L<strong>and</strong>sat Mosaic Images<br />

A Windows-based computer program has been written to enable novice users (especially educators <strong>and</strong> students) to view<br />
images of large areas of the Earth (e.g., the continental USA) generated from image data acquired in the L<strong>and</strong>sat observations<br />
performed circa the year 1990. The large-area images are constructed as mosaics from the original L<strong>and</strong>sat images, which were<br />
acquired in several wavelength b<strong>and</strong>s <strong>and</strong> each of which spans an area (in effect, one tile of a mosaic) of 5 in latitude by<br />
approximately equal to 6 degrees in longitude. Whereas the original L<strong>and</strong>sat data are registered on a universal transverse<br />
Mercator (UTM) grid, the program converts the UTM coordinates of a mouse pointer in the image to latitude <strong>and</strong> longitude,<br />
which are continuously updated <strong>and</strong> displayed as the pointer is moved. The mosaic image currently on display can be exported<br />
as a Windows bit-map file. Other images (e.g., of state boundaries or interstate highways) can be overlaid on L<strong>and</strong>sat mosaics.<br />
The program interacts with the user via st<strong>and</strong>ard toolbar, keyboard, <strong>and</strong> mouse user interfaces. The program is supplied on<br />
a compact disk along with tutorial <strong>and</strong> educational information.<br />

Software for Improved Extraction of Data From Tape Storage<br />

A computer program has been written to replace the original software of Racal Storeplex Delta tape recorders, which are<br />
still used at Stennis Space Center but have been discontinued by the manufacturer. Whereas the original software could be<br />
activated by a comm<strong>and</strong>-line interface only, the present software offers the option of a comm<strong>and</strong>-line or graphical user<br />
interface. The present software also offers the option of batch-file operation (activation by a file that contains comm<strong>and</strong> lines<br />
for operations performed consecutively). The present software is also more reliable than was the original software: The<br />
original software was plagued by several deficiencies that made it difficult to execute, modify, <strong>and</strong> test. In addition, when using<br />
the original software to extract data that had been recorded within specified intervals of time, the resolution with which one<br />
could control starting <strong>and</strong> stopping times was no finer than about a second (or, in some cases, several seconds). In contrast,<br />
the present software is capable of controlling playback times to within 1/100 second of times specified by the user, assuming<br />
that the tape-recorder clock is accurate to within 1/100 second.<br />
