NASA-LLIS-1803: Lessons Learned – CSAM Augments X-Ray Inspection of Die Attach (MRO Ka-Band Anomaly)
Abstract: Abstract:
An in-flight failure of a hybrid amplifier used to derive the Ka-band downlink signal for Mars Reconnaissance Orbiter suggests that X-ray screening alone may not be adequate to determine the ...
