Space Environments Research to Application (SERA)
NASA’s Marshall Space Flight Center has established the Space Environments Research to Applications (SERA) working group. SERA is an ad hoc organization composed of discipline experts from across the Center and is focused on promoting space environments research and transitioning this research to applications at MSFC, within NASA, nationally, and internationally where appropriate. There exists numerous and varied capabilities focused on space environments at MSFC, and one of SERA’s goals is to strategically use these unique capabilities to promote space environments research to benefit mankind. SERA’s purpose is to enable, sustain, promote, and enhance space environment research and knowledge of space environment influence on space systems performance. The SERA working group will provide coordination, as appropriate, to facilitate space environment research and transition this knowledge in applications-driven products. This transition will occur most commonly, however not always, as integration into the mission life cycle. SERA will advocate for the advancement of solution-driven investments in space weather research and space effects on space systems performance. SERA will include, but not be limited to, the disciplines of heliophysics research, space weather effects, space environment characterization, and environmental effects testing and analysis for space materials and systems. SERA will, when appropriate, facilitate cooperation between NASA MSFC and the commercial aerospace industry, other federal agencies, and other NASA field centers. SERA will support NASA HQ in relevant activities as requested. The goal of SERA at MSFC is to enable mission success through the transitioning of space weather and environment knowledge from research/science to operations/engineering applications.

Satellite Contamination and Materials Outgassing Knowledgebase - This knowledgebase was originally developed by Bob Wood for the Space Environments and Effects (SEE) Program office and was distributed, for many years, through the SEE website http://see.msfc.nasa.gov as a stand-alone PC-based knowledgebase. Recent discussions among the National and International space environments and effects community helped codify a decision to enhance the accessibility and availability of SCMOK within MAPTIS.
The SCMOK is an interactive, menu-driven database that provides outgassing properties of aerospace materials based upon ground-testing data, the effects of outgassing, and contaminant re-deposition that has been observed during space flight.
The knowledgebase contains information using the ASTM Standard E-1559 and also consolidates data from missions using Quartz-Crystal Microbalances (QCM’s). The data contained in the knowledgebase was shared with NASA by government agencies, industries, and international space agencies.
Access to the SCMOK may be obtained through a hot link for requesting a User ID and Password from the SEE web page http://see.msfc.nasa.gov/db_contam, or directly from the MAPTIS site administrator, http://maptis.nasa.gov/Request.aspx
Earth Global Reference Atmospheric Model (Earth-GRAM 2010) - Global model, using empirical database, giving density, temperature, pressure, winds, and selected atmospheric constituent concentrations, from the surface of the Earth to orbital altitudes, as a function of geographic position and time of year. Local perturbations about mean conditions are also included. Model is also suitable for use as a subroutine in a trajectory code or orbit propagator program or other programs used for simulations of in-flight or on-orbit atmospheric variability in density, temperature, or winds.
Mars Global Reference Atmospheric Model (Mars-GRAM 2010) - Mars Global Reference Atmospheric Model (Mars-GRAM) is an engineering-level atmospheric model, widely used for diverse mission applications. Applications include systems design, performance analysis, and operations planning for aerobraking, entry descent and landing, and aerocapture. From 0-80 km altitude, Mars-GRAM is based on NASA Ames Mars General Circulation Model (MGCM), while above 80 km it is based on Mars Thermospheric General Circulation Model (MTGCM). Mars-GRAM and MGCM use surface topography from Mars Global Surveyor Mars Orbiting Laser Altimeter (MOLA), with altitudes referenced to the MOLA constant potential surface (areoid). (public domain)
Venus Global Reference Atmospheric Model (Venus-GRAM 2005) - Marshall Space Flight Center’s Natural Environments Branch has developed Global Reference Atmospheric Models (GRAMs) for Mars, Venus, Earth, and other solar system destinations. Venus-GRAM is based on the Committee on Space Research (COSPAR) Venus International Reference Atmosphere (VIRA), and is suitable for a variety of engineering applications at all attitudes, locations, and times within the atmosphere of Venus.

Lunar E-Library -The Lunar E-Library is a searchable web interface of electronic documents and other resources to aid managers, engineers, and scientists identify key lessons learned from the Apollo and other Lunar missions. The Lunar e-Library focuses on Apollo/Saturn era documents and includes 870 complete electronic documents and 230 abstracts with source information for copyrighted and limited distribution material. It features an easy-to-use search engine that searches the entire 1,100 documents and abstracts at once. An index is included, and the user can conduct advanced searches by title, author and other information criteria.
The Lunar e-Library literature collection includes a complete set of the Apollo mission and science reports; the Apollo Experience Reports; the Saturn V Flight Evaluation Reports; Lunar Roving Vehicle documents; documents on lunar soil and lunar surface studies; historical documents with an emphasis on Apollo and lunar studies; lunar data and experiment documents from the Surveyor, Apollo, Clementine and Lunar Prospector missions; studies and lunar reference mission documents, including Space Exploration Initiative and the First Lunar Outpost documents.
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.
