Explanation

Please explain in the area below why an STA is necessary: This request is to modify Special Condition (1) on an STA already granted, FCC File No. 0927-EX-ST-2020 (WQ9XUS), to extend the duration in orbit, post-ISS departure, to 39 days total. The extended time is needed due to the increased scope of mission operations planned for the post-ISS departure phase of flight operations. The additional 39 days is within the original term of the existing STA. Additional information is in the attached exhibit. Contact Derrick Delahaye, 703-406-5834, for additional information.
