Integrated Mission Program (IMP) is a computer program for simulating spacecraft missions around the Earth, Moon, Mars, and-or other large bodies. IMP solves the differential equations of motion by use of a Runge-Kutta numerical-integration algorithm. Users control missions through selection from a large menu of events and maneuvers.

Introducción



Software Software for Viewing Landsat Mosaic Images A Windows-based computer program has been written to enable novice users (especially educators and students) to view images of large areas of the Earth (e.g., the continental United States) generated from image data acquired in the Landsat observations performed circa the year 1990. The large-area images are constructed as mosaics from the original Landsat images, which were acquired in several wavelength bands and each of which spans an area (in effect, one tile of a mosaic) of ≈5° in latitude by ≈6° in longitude.
Whereas the original Landsat data are registered on a universal transverse Mercator (UTM) grid, the program converts the UTM coordinates of a mouse pointer in the image to latitude and longitude, which are continuously updated and displayed as the pointer is moved.
The mosaic image currently on display can be exported as a Windows bitmap file.
Other images (e.g., of state boundaries or interstate highways) can be overlaid on Landsat mosaics.
The program interacts with the user via standard toolbar, keyboard, and mouse user interfaces.
The program is supplied on a compact disk along with tutorial and educational information. This program was written by Zack Watts, Catharine L.
Farve, and Craig Harvey of PixSell, Inc., for Stennis Space Center. In accordance with Public Law 96-517, the contractor has elected to retain title to this invention.
Inquiries concerning rights for its commercial use should be addressed to PixSell, Inc.
