  WHAT'S NEW

Man in Spacesuit   Earth   Spacestation


2007 Meteoroid Environments Workshop Presentations

Lunar E-Library - This DVD knowledgebase contains 1100 (.PDF) items with an emphasis on documents produced during the Apollo/Saturn era. Full text is available for 870 documents, and abstracts with source information are included for 230 documents that are copyrighted or limited distribution materials.  

NASA/Air Force Spacecraft Charging Analyzer Program (NASCAP-2K) - NASCAP-2K is the next generation spacecraft charging analysis code.  It is a comprehensive update to the original NASCAP spacecraft charging codes written twenty years ago.  As a collaboration between NASA and the US Air Force Research Lab (AFRL), it builds upon the Air Foce's DynaPAC charging algorithms and will replace 3-D spacecraft charging codes for all environments.

Electronic Propulsion Interactions Code (EPIC) - EPIC is an interactive computer toolset that allows the construction of a 3-D spacecraft model and the assessment of a variety of interactions between its subsystems and the plume from an electric thruster.

Satellite Contamination and Materials Outgassing Knowledgebase  - This knowledgebase is the combination of ASTM E1559 and Space QCM flight data databases providing the coordination of tested materials properties to effects observed in flight.  

Living With a Star (LWS) / Space Environments Testbed (SET) -


The Charge Collector (LEO Charging Guidelines included in the latest version) - The Charge Collector is a compilation of spacecraft charging-related products offered by NASA's SEE Program.  The information contained herein was developed by various organizations of government, industry and academia, all under contract to the SEE Program.  Type of information contained the Charge Collector include databases, reports, tabulated data and design guidelines.

Trapped Proton Model (TPM-1) - The model determines the differential omnidirectional proton flux from 1–100MeV.  At high altitudes the model is based on CRRESPRO, developed by AFRL; at low altitudes, the model is based on data from the TIROS/NOAA (POES) low-altitude polar-orbiting satellites.  The model contains a true solar cycle variation and also contains sub-models for quiet and active magnetospheric states.

Spacecraft Materials Selector Expert System - The Spacecraft Materials Selector (SMS) knowledge base is a preliminary design tool that provides estimates of environmental exposures and/or materials performance for selected spacecraft materials.
