Special Temporary Authority application - Explanation

Please explain in the area below why an STA is necessary:
A special temporary authority is requested for the REAL cubesat to extend the mission of the spacecraft currently on orbit. The current STA, 0003-EX-ST-2026, covers the period to July 19, 2026. The extension is necessary to complete the missions research, including scientific research associated with understanding Earths Van Allen radiation belts, as well as tuning and qualifying the instruments to reduce risk on planned missions. This will allow us to achieve the goals of debugging and tuning the sensor suite, as well as completing the science data collection goals of the mission.

Special Temporary Authority application - Purpose of Operation

Please explain the purpose of operation:
Conduct scientific research associated with understanding Earths Van Allen radiation belts using the REAL cubesat. The demonstration will consist of a point-to-point downlink (in both RHCP and LHCP) from an S-band transmitter, on a 3U low earth orbit cubesat (referred to as REAL), to an existing 18.3 m earth station (ES) in S-band. The S-band ES is located in Laurel, Maryland, and is owned and operated by Johns Hopkins University Applied Physics Lab. The REAL satellite will also be equipped with a UHF transceiver for telecommand, tracking, and receipt of health data. The UHF-band radio will receive telecommand signals from and transmit telemetry to an earth station located in Bozeman, Montana that is owned and operated by Montana State University. All emissions will cease after the completion of the six-month demonstration. Please see Exhibit 1 for more information on the plan and objectives.
