Database

Electronic databases containing the results of studies in the following areas were constructed by Boeing Defense and Space Group as part of the Materials Special Investigations. These databases contain information that was available through the Second LDEF Post-Retrieval Symposium proceedings, published in April 1993 (NASA CP-3194).

• Treated Aluminum Hardware
• Silverized Teflon^®
• Thermal Control Paints

In addition, an electronic database was constructed by Boeing Defense and Space Group as part of Systems and Materials Special Investigations that focusses upon:

• Optical Materials

This database is current through the results of the Third LDEF Post-Retrieval Symposium proceeding, published in February 1995 (NASA CP-3275).

These databases contain descriptions of the experiments and hardware flown, experiment results, and a systems analysis overview applicable to spacecraft design guidelines and space environmental effects. Thee databases are available in both IBM compatible and MacIntosh (TM) versions that run on Filemaker Pro(TM) software. These databases are also available through the LDEF Archive Office. A companion database documenting the exposure levels to each space environment factor as a function of location on the LDEF structure was also created. It is entitled "LDEF Environments".

LDEF MSIG Database on the Materials and Process Technical Information Systems (MAPTIS)

The LDEF Materials Database has been incorporated into NASA Marshall Space Flight Center's Materials and Processes Technical Information System (MAPTIS). The goal of MAPTIS is to provide an efficient and reliable means of supplying information needed for the selection and application of materials and processes to produce the hardware required for NASA's and industry's space missions. To access the MAPTIS system, users must first establish an account. To request a MAPTIS account, please submit the following information to Rene Hitson / John Davis at NASA MSFC / MAPTIS.

Employee Name:
Company / Mail Code:
Work Address:

The information can be faxed to (256) 544-5786. Alternately, you can call Rene Hitson at (256) 544-6972 or John Davis at (256) 544-2494.

If you already have an account you can access MAPTIS here.

A version of the MAPTIS LDEF Materials Database is also available for use with PDA Engineering's M/Vision (TM) software. M/Vision is a materials software system that contains graphics, spreadsheets, imaging and modelling and databasing capabilities.

Further information on all of the LDEF Materials Databases can be found in: J.G. Funk, J.W. Strickland and J.M. Davis, LDEF Materials Databases, NASA Technical Memorandum 107757, June 1993.

LDEF Experiment M0003 Observational Database

An extensive photographic and electronic database of post-retrieval observations was compiled during the deintegration of the Aerospace Corporation M0003 Experiment, Space Environmental Effects on Spacecraft Materials. The Aerospace Corporation is distributing the database records and photographs generated in the post-flight microscopy examination of the M0003 samples to the general community through its Library Archives. Aerospace Corporation has produced an electronic database for use with 4^th Dimension software [ACIUS Corp] for the MacIntosh and Paradox software (Borland Corp.) for IBM PCs. Further information can be found in: M0003 Database Guide Book, The Aerospace Corporation, June 1992.

SETAS LDEF Material Database

As part of the SETAS development effort, a prototype LDEF materials database was developed. A searchable view of this database based on material category is available.
