Explanation
Please explain in the area below why an STA is necessary:
Sierra Space seeks a Special Temporary Authority for testing of its Dream Chaser spacecraft planned to be launched for a mission to support cargo delivery to and from the International Space Station. Sierra Space is requesting an STA for testing to occur between June 2024 and November 2024. The testing will support Sierra Space Corporation's DC-101 mission using the Dream Chaser Cargo System (DCCS), as part of the NASA Commercial Resupply Services.

Purpose of Operation
Please explain the purpose of operation:  The EMC test and RF capabilities of the vehicle testing will demonstrate, amongst other, that electromagnetic interference characteristics of the subsystem, under normal operating. conditions, do not result in malfunction of the subsystem. It also demonstrates that the subsystem does not emit, radiate, or conduct interference, which could result in malfunction of other subsystems. Sierra space's point-of-contact information to permit the prompt delivery at all times of notices of harmful interference includes Mr. Ronak Shah, Test Engineer (Director of Testing), Ronak.Shah@sierraspace.com, 303-542-7828 He is the initial point of contact for all matters involving interference resolution and has authority to discontinue any and all experiments being conducted under an STA grant, if necessary.
