NASA-LLIS-2036: Lessons Learned – Provide a Design Capability Allowing Key Mechanical Adjustments After Subsystem Integration
Abstract: Abstract:
The Tunable Laser Spectrometer (TLS) are sensitive to optical standing wave contamination that can be ameliorated by making small adjustments in instrument alignment after system integration. ...

NASA-LLIS-5479: Lessons Learned - Proper Manufacturing, Handling, Use, Storage and Care Of Metal Bellows Flex Hoses
Abstract: Metal bellows flex hoses are very susceptible to reverse bending low cycle fatigue which results in leakage via a through crack in the bellows.
NASA-LLIS-2038: Lessons Learned – To Bond or to Bolt, That is the Question [Export Version]
Abstract: Abstract:
Following vibration test and bakeout of the OSTM Advanced Microwave Radiometer (AMR) Reflector Structure Assembly (RSA), it was discovered that thermal stress had caused delamination in the ...
