2003 Award Co-Winners

Award Title:

NASGRO™ Fracture Mechanics Analysis Software

Lead NASA Center:

Johnson Space Center (JSC)

Case Number:

MSC-23600-1

Summary:

NASGRO is the internationally accepted standard code for fracture control analysis of space hardware. The code has important use on the Space Shuttle and the ISS Programs including analysis of payloads and resolution of crack-like anomalies. The current version 4.0, completed in May 2002, was developed through a mutual development agreement between JSC and Southwest Research Institute (SwRI)—manager of the NASGRO Consortium consisting of 14 private companies. NASGRO has been significantly improved over the 1994 NASA/FLAGRO version. Besides the application for space hardware, over 1700 users of NASGRO are identified representing over 600 companies and including space, civil aviation, military and university communities. NASGRO is the standard code for fracture analysis of space hardware, aircraft, rotorcraft, turbine engines and many other pieces of mechanical equipment. Of particular note, NASGRO is receiving significant support from the FAA for development of improved capabilities for damage tolerance analysis of aircraft.


Award Title:

The SeaWiFS Data Analysis System (SeaDAS)

Lead NASA Center:

Goddard Space Flight Center (GSFC)

Case Number:

GSC-14719-1

Summary:

From the start of the Sea-viewing Wide Field of view Sensor (SeaWiFS) Project in 1991 at NASA/GSFC, providing rapid and easy data access to the user community has been a primary objective along with ensuring that the data were of the highest possible quality. For NASA to maximize its investment in Earth remote sensing, data not only must be delivered to the user community in a timely manner but, the users must have the tools to work with the data. The SeaWiFS Data Analysis System (SeaDAS) was the answer to providing data display, processing, and analysis support. SeaDAS was designed to identically reproduce all the standard products, including levels 1, 2, and 3 (raw telemetry counts to level 3 global mapped geophysical products), generated by the SeaWiFS Project Office (SPO), while providing users the flexibility of customized processing by adjusting processing parameters or selecting alternative processing methods. SeaDAS is provided as packaged executable software and source code (for those who wanted to incorporate new capabilities), and also includes on-line help, demonstrations, along with very responsive e-mail and telephone support. Additional requirements were for SeaDAS to run on affordable and commonly used desktop systems, e.g., Silicon Graphics and Sun Microsystems Unix workstations, and have an easy to use graphical user interface (GUI). Later, support was added for PC Linux systems, which greatly expanded the user base, especially overseas. SeaWiFS was successfully launched in 1997 and has since provided continuous Earth observations. SeaDAS was broadly distributed prior to launch and was used by many in the research community to evaluate the initial SeaWiFS data on the first day of operations. Today, SeaDAS is being used at over 500 sites in nearly 50 countries. The SeaDAS official web site is located at: http://seadas.gsfc.nasa.gov/.
