REQUESTS FOR SPECIAL TEMPORARY AUTHORITY Spaceflight Inc. ("Spaceflight"), pursuant to Section 25.120 of the Commission‘s Rules, hereby requests Special Temporary Authority ("STA") to permit it to ' communicate with a spacecraft, known as SHERPA, and corresponding earth stations for a duration of up to twelve (12) hours to take place in a single occurrence between January 15, 2016 and April 15, 2016.1 As described in greater detail in the attached Technical Annex, SHERPA is a non— propulsive, free—flying spacecraft intended to deploy auxiliary spacecraft from each of five ports. SHERPA itself is proposed to be affixed to the payload on a Falcon 9 launch that is currently scheduled to occur within above—stated launch period. SHERPA will be placed in a sun synchronous elliptical orbit of 720 x 450 km, 97.4 degree inclination. After its deployment from the launch vehicle, SHERPA will initiate a sequence of procedures to begin the deployment of its own payload and the communication that is . the subject of the instant requests will commence. Spaceflight seeks authority to permit it to establish communications between SHERPA and three earth stations during the twelve—hour operational of the SHERPA payload.2 The communications links, which will consist of two—way data transmissions, will permit the Spaceflight technical crew to track the launch and download status information from SHERPA. The proposed frequencies for communication to and from SHERPA are UHF frequencies authorized under the FCC‘s Table of Frequency Allocations for space operations. The payload of SHERPA will consist of small spacecraft that are owned and to be operated by Spaceflight‘s customers. Each customer is expressly required under its agreement with Spaceflight to obtain all licenses, authorization, clearances, and permits that may be necessary to operate its individual spacecraft. — Spaceflight asserts that grant of the instant requests for Special Temporary Authority will be in the public interest. Such grant will permit Spaceflight to initiate a new and innovative deployment technology for small spacecraft, thereby providing a cost—efficient means for placing them into their designed orbits. 1 Recent developments in the spacecraft launch industry have resulted in a number of launch delays and uncertainties as to when future launches will occur. The timeframe set forth above reflects the current launch period assigned for the Spaceflight launch. Spaceflight has not yet been assigned an exact date of the SHERPA launch. Accordingly, Spaceflight is herein seeking STA to cover a period of three (3) months. However, as described herein, the actual communications for which STA is sought will occur over a period of only twelve (12) hours. Spaceflight will notify the Commission as its launch period is narrowed to a particular day as soon as that information is confirmed to it by the launch provider. 2 Spaceflight is submitting concurrently unique applications for space station STA to cover the communications of SHERPA and earth station STA to cover the ground station locations.

Technical Annex: Spaceflight SHERPA Spacecraft Description The Spaceflight SHERPA spacecraft is a non—propulsive, free—flying spacecraft intended to deploy auxiliary spacecraft from each of five ports. The spacecraft is primarily composed of commercial off the shelf (COTS) hardware, with the core structure being a custom ESPA Grande ring. Auxiliary satellites are integrated to each port using simple plates and separated using proven separation systems, such as the Planetary Systems Corporation (PSC) Motorized Lightband (MLB) and the Innovative Solutions in Space (ISIS) QuadPack. The configuration, shown in Figure 1, is intended to deploy three microsatellites using MLBs as well as several CubeSats and nanosatellites from twenty—one (21) QuadPack dispensers. Each QuadPack holds 12VU worth of CubeSat payload. A CubeSat, based on the Cal Poly CubeSat standard, has nominal dimensions 10 x 10 x 10 cm. SHERPA runs flight software on COTS Andrews Space CORTEX avionics and it is equipped with its own power and power distribution system to deploy each auxiliary spacecraft in a pre—programmed sequence. The primary mission is satisfied by successful deployment of each auxiliary payload. The confirmation of successful payload deployment is given by the transmission of telemetry containing SHERPA state vectors taken upon each discrete deployment event. The SHERPA mission itself is expected to last approximately Figure 1. SHERPA Spacecraft shown thebrimerybayload.TheprimarypayloadtslaunchedInto_ . * ‘ Mlegrated with the Payload Attach Fitting {below) and the Primary Payload Adapter 720 km circular sun synchronous orbit and then separated. (above) The upper stage, with SHERPA attached, executes a maneuver to lower the perigee of the orbit to 450 km and change the inclination to 97.4 degrees. At this orbit, SHERPA is separated from the upper stage. The separation event activates the SHERPA spacecraft through the closing of separation switches, which will turn on for the first time. After initialization, SHERPA begins a pre—programmed sequence of deployments. No uplink is necessary to begin deployments. For each deployment event time, position, and velocity (determined via GPS receiver) are logged in the form of a state vector to be transmitted. Upon completion of deployments, SHERPA transmits the telemetry to a ground station. SHERPA‘s communication system utilizes an onboard UHF radio with 4 antenna. SHERPA batteries are expected to last for duration less than 20 hours until they‘re expended. Ultimately, SHERPA de—orbits through orbital decay due to atmospheric drag approximately 20 years after launch.

Radiation Hazard Report . Exhibit Page 1 of 5 Analysis of Non—lonizing Radiation for a 3.05—Meter Yagi Antenna Earth Station System This report analyzes the non—ionizing radiation levels for a 3.05—meter Yagi antenna earth station system. The analysis and calculations performed in this report comply with the methods described in the FCC Office of Engineering and Technology‘s General RF Exposure Guidance, 447498 DO1 vO5r02. The radiation safety limits used in the analysis are in conformance with Title 47 Chapter I, Subchapter A, Part 1, Subpart I, Section 1.1310. Section 1.1310 specifies that there are two separate tiers of exposure limits that are dependent on the situation in which the exposure takes place and/or the status of the individuals who are subject to the exposure. The Maximum Permissible Exposure (MPE) limits for persons in a General Population/Uncontrolled environment are shown in Table 1. The General Population/Uncontrolled MPE is a function of transmit frequency and is for an exposure period of thirty minutes or less. The MPE limits for persons in an Occupational/Controlled environment are shown in Table 2. The Occupational MPE is a function of transmit frequency and is for an exposure period of six minutes or less. The purpose of the analysis described in this report is to determine the power flux density levels of the earth station in the far—field, near—field, transition region, and between the antenna edge and the ground and to compare these levels to the specified MPEs.

Radiation Hazard Report Exhibit Page 3 of 5 1. Far Field Distance Calculation A The distance to the beginning of the far field can be determined from the following equation: Distance to the Far Field Region Rf = 0.60 D/A (1) = 8.36 m The maximum main beam power density in the far field can be determined from the following equation: On—Axis Power Density in the Far Field S = GP/(A4mtRy") (2) = 0.23 W/m? = 0.023 mW/cm* 2. Near Field Calculation Power flux density is considered to be at a maximum value throughout the entire length of the defined Near Field region. The region is contained within a cylindrical volume having the same surface area as the antenna. Past the boundary of the Near Field region, the power density from the antenna decreases linearly with respect to increasing distance. The distance to the end of the Near Field can be determined from the following equation: Extent of the Near Field Rp; = D* /(42) (3) = 3.48 m The maximum power density in the Near Field can be determined from the following equation: Near Field Power Density Saft = 41P/Agurface (4) = 12.8 W/m = 1.28 mW/cm* 3. Transition Region Calculation The Transition region is located between the Near and Far Field regions. The power density begins to decrease linearly with increasing distance in the Transition region. While the power density decreases inversely with distance in the Transition region, the power density decreases inversely with the square of the distance in the Far Field region. The maximum power density in the Transition region will not exceed that calculated for the Near Field region. The power density calculated in Section 2 is the highest power density the antenna can produce in any of the regions away from the antenna. The power density at a distance Ry can be determined from the following equation: Transition Region Power Density Stz = SnfRnf/Rtz (5) = 1.28 mW/cm* Rr is calculated at a distance of 3.48 meters from the antenna, which is the worst—case distance. This is the edge of the near—field, Rnf.

Radiation Hazard Report Exhibit Page 4 of 5 4. Region between the Antenna and the Ground Assuming uniform illumination of the antenna surface, the power density between the antenna and the ground can be determined from the following equation: Power Density between Antenna and Ground Sg = P/Agurface (6) = 3.37 W/m* = 0.337 mW/cm* 5.

Radiation Hazard Report Exhibit Page 5 of 5 6. Conclusions Based upon the above analysis, it is concluded that FCC RF Guidelines have been exceeded in the Near Field, the Transition Zone, and the region between the Antenna and the Ground of the Uncontrolled (Table 4) environment. In the Controlled (Table 5) environments none of the regions have levels that: exceed the FCC RF Guidelines. The applicant proposes to comply with the Maximum Permissible Exposure (MPE) limits of 0.3 mW/cm> for the Uncontrolled Areas, and the MPE limits of 1.5 mW/cm? for the Controlled Areas. The earth station Yagi antenna will be mounted on a platform; so the applicant agrees that the antenna will be in an area secured from the public and worker personnel not familiar with the earth station system. Non—assigned worker personnel and the general public must be accompanied by knowledgeable earth station personnel when they enter the earth station secured area. The earth station‘s secured area will be marked with the required radiation hazard signs as described in the recent FCC R&O 13—39. The area in the vicinity of the earth station secured area will also have signs to inform those in the general population and those who may be working in the area or otherwise present that they are close to a RF System capable of producing hazardous levels. The applicant agrees to abide by the conditions specified in Condition 5208 provided below: Condition 5208 — The licensee shall take all necessary measures to ensure that the antenna does not create potential exposure ofhumans to radiofrequency radiation in excess ofthe FCC exposure limits defined in 47 CFR 1.1307(b) and 1.1310 wherever such exposures might occur. Measures must be taken to ensure compliance with limitsfor both occupational/controlled exposure andfor general population/uncontrolled exposure, as defined in these rule sections. Compliance can be accomplished in most cases by appropriate restrictions such asfencing. Requirementsfor restrictions can be determined by predictions based on calculations, modeling or by field measurements. The FCC‘s OET Bulletin 65 (available on—line at wwwfee.gov/oet/rfsafety) provides information on predicting exposure levels and on methodsfor ensuring compliance, including the use of warning and alerting signs andprotective equipmentfor worker.
