The Photogrammetric Appendage Structural Dynamics Experiment (PASDE) was developed to
demonstrate the use of photogrammetric techniques for structural dynamic response measurements of spacecraft solar arrays and
similar structures.
A photogrammetric structural dynamic response measurement instrument was designed, fabricated, assembled, and
tested at the NASA Langley Research Center in 8 months to meet a flight experiment opportunity on the second joint
NASA/RSA Shuttle/Mir mission (STS-74) in November 1995.
