After a brief stopover in systems test complex C-10, the vehicle was transferred to the anechoic chamber for elecromagnetic interference and radio-frequency-interference tests.

Tests preparations began February 23. At this point, GATV 5001 was 37 calendar days behind schedule, 20 days of which were caused by the time-accumulator anomaly that had developed during hot-firing tests. A temporary fix for the time-accumulator jumps was installed, while Lockheed continued its efforts to diagnose the problem and find a permanent remedy.
