Virtual Satellite

Virtual Satellite (VirtualSat) is a computer program that creates an environment that facilitates the development, verification, and validation of flight software for a single spacecraft or for multiple spacecraft flying in formation. In this environment, enhanced functionality and autonomy of navigation, guidance, and control systems of a spacecraft are provided by a virtual satellite — that is, a computational model that simulates the dynamic behavior of the spacecraft.

Small-Body Extensions for the Satellite Orbit Analysis Program (SOAP)

An extension to the SOAP software allows users to work with tri-axial ellip-soid-based representations of planetary bodies, primarily for working with small, natural satellites, asteroids, and comets. SOAP is a widely used tool for the visualization and analysis of space missions. The small body extension provides the same visualization and analysis constructs for use with small bodies. These constructs allow the user to characterize satellite path and instrument cover information for small bodies in both 3D display and numerical output formats.

Scripting Module for the Satellite Orbit Analysis Program (SOAP)

This add-on module to the SOAP software can perform changes to simulation objects based on the occurrence of specific conditions. This allows the software to encompass simulation response of scheduled or physical events. Users can manipulate objects in the simulation environment under programmatic control. Inputs to the scripting module are Actions, Conditions, and the Script. Actions are arbitrary modifications to constructs such as Platform Objects (i.e. satellites), Sensor Objects (representing instruments or communication links), or Analysis Objects (user-defined logical or numeric variables). Examples of actions include changes to a satellite orbit ( v), changing a sensor-pointing direction, and the manipulation of a numerical expression. Conditions represent the circumstances under which Actions are performed and can be couched in If-Then-Else logic, like performing v at specific times or adding to the spacecraft power only when it is being illuminated by the Sun.

Core Technical Capability Laboratory Management System

The Core Technical Capability Lab - oratory Management System (CTCLMS) consists of dynamically generated Web pages used to access a database containing detailed CTC lab data with the software hosted on a server that allows users to have remote access. Users log into the system with their KSC (or other domain) username and password. They are authenticated within that domain and their CTCLMS user privileges are then authenticated within the system. Based on the different user’s privileges (roles), menu options are displayed. CTCLMS users are assigned roles such as Lab Member, Lab Manager, Natural Neighbor Integration Manager, Organ - izational Manager, CTC Program Manager, or Administrator. The role assigned determines the users’ capabilities within the system. Users navigate the menu to view, edit, modify or delete laboratory and equipment data, generate financial and managerial reports, and perform other CTC lab-related functions and analyses.

MRO SOW Daily Script

The MRO SOW daily script (wherein “MRO” signifies “Mars Reconnaissance Orbiter” and “SOW” signifies “sequence systems engineer of the week”) is a computer program that automates portions of the MRO daily SOW procedure, which includes checking file-system sizes and automated sequence processor (ASP) log files. The MRO SOW daily script effects clear reporting of (1) the status of, and requirements imposed on, the file system and (2) the ASP log files.

NASA Celebrates 50 Years

“The exploration of space will go ahead, whether we join it or not, and it is one of the greatest adventures of all time, and no nation which expects to be the leader of other nations can expect to stay behind in this race for space. “We set sail on this new sea because there is new knowledge to be gained and new rights to be won, and they must be won and used for all people. “We choose to go to the Moon. We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard, because the goal will serve to organize and measure the best of our energies and skills.” President John F. Kennedy Rice University September 12, 1962

50 Years of Inspiration

We wanted NASA Tech Briefs readers to be a part of our special issue celebrating NASA’s 50th anniversary. So, we asked you to tell us how NASA, and NASA Tech Briefs, have inspired you over the past 50 years. We wanted to know how NASA helped you in your career or business, or improved your everyday life. What benefits have you derived from NASA technologies? Although space prohibits publishing every comment here, we thank all of you who shared your stories of inspiration with us.
