Welcome!
Welcome to the 3rd edition of the NESC News!For this edition of the NESC News, we highlight selected ongoing technical work that is taking place in the NESC to resolve complex engineering challenges at NASA. These projects were included in the NESC 2009 Technical Update. The NESC is currently working on the 2010 Technical Update that should be released early next fiscal year. Annually, the NESC Technical Update team integrates information related to ongoing projects, new testing results and analyses, and documents this information in an annual report. The Technical Update also includes updates from each of the NASA centers where NESC work takes place. Other sections of the Technical Update include honor award information, biographies of key NESC personnel, a listing of NESC publications for the year, and papers presented at conferences. If you have not seen a complete addition of the NESC Technical Update, you can download a pdf version at Technical Updates/Bulletins, otherwise enjoy reading about the activities provided below and thank you for your interest in the NESC.
Also, check out the informative videos by Scott Horowitz, retired NASA astronaut, and other key members of the recent Composite Crew Module (CCM) project.
Orbital Debris Risk Assessment
Micrometeoroid and orbital debris (MMOD) is millions of naturally occurring micrometeoroids and man-made debris that orbit in and around Earth’s space environment at hypervelocity speeds averaging 10km/s (22,000 mph). The NESC team analyzed the MMOD risk for the Orion crew module.

Shell Buckling Knockdown Factor (SBKF)
An Ares V-style shell under test at MSFC.
To improve Shell Buckling Knockdown Factor (SBKF) for the Constellation Program the team conducted a number of sub-component and component testing and analysis. This NESC work continues though FY09 and into FY10.

Composite Overwrapped Pressure Vessel (COPV)
A composite overwrapped pressure vessel (COPV) is a vessel consisting of a thin, non-structural liner wrapped with a structural fiber composite, designed to hold a fluid under pressure. The NESC team analyzed the life prediction model for failure mode of composite materials.

Entry, Descent, and Landing (EDL) Flight Simulations
Entry, descent, and landing (EDL) flight simulations developed do not outlive their usefulness once the program or project is finished. These simulations can benefit other projects and programs and so should be preserved and easily accessible to those needing the information. The NESC team is converting and archiving relevant EDL simulations data.
