                  REQUEST FOR EXTENSION OF SPECIAL TEMPORARY AUTHORITY
       On May 9, 2019, the Commission granted Space Exploration Holdings, LLC (“SpaceX”)
Special Temporary Authority (“STA”) for the first tranche of its non-geostationary orbit
(“NGSO”) satellites launched on May 24, 2019 to communicate with seven earth stations operated
by its sister company, SpaceX Services, Inc. (“SpaceX Services”). 1 The Commission
subsequently extended that STA through August 24, 2019. 2 SpaceX respectfully requests that the
Commission further extend that STA for an additional 30 days for the reasons discussed below.
         SpaceX has been authorized to launch and operate a constellation of 4,409 NGSO satellites
(call sign S2983/S3018) using Ku- and Ka-band spectrum. Pursuant to the STA, SpaceX has been
communicating with an earth station to conduct telemetry, tracking, and control (“TT&C”)
functions during orbit raising and initial on-station operations, 3 and has also been communicating
with six Ku-band gateway earth stations to test the communications payload on each of its
satellites. 4 SpaceX has operated with these earth station pursuant to the STA for nearly three
months, and has received no complaints from any other authorized spectrum user.
        Allowing continued communications between the SpaceX space stations and SpaceX
Services earth stations while applications for the latter are being processed would serve the public
interest. The STA covers TT&C functions that are essential to commanding the spacecraft and
ensuring the health and safety of SpaceX’s nascent constellation. The STA also allows SpaceX to
confirm the operational status of its satellites on an ongoing basis. While much of the orbit-raising
phase is now complete, there are still some satellites that have yet to reach their authorized altitude.
In addition, there are two spacecraft that are being intentionally de-orbited in order to assess
performance during this phase of the mission. Extending the STA would allow SpaceX to continue
to provide TT&C functions that are essential to commanding all of these spacecraft and ensuring
continuing monitoring of and control over SpaceX’s nascent constellation, as well as maintaining
communications with these craft to assess their functionality. Accordingly, extension of the STA
will continue serve the public interest by enhancing space safety and promoting the health and
safety of SpaceX’s NGSO constellation.
        SpaceX will continue to operate on a non-interference basis, and in conformance with the
applicable equivalent power flux-density (“EPFD”) limits set forth in Article 22 and Resolution
76 of the ITU Radio Regulations and the applicable power flux-density (“PFD”) limits set forth in

1
    See Public Notice, Rep. No. SAT-01388 (rel. May 10, 2019). As required under the STA, SpaceX confirmed
    the launch and commencement of operations date for its satellites, which began the term of the STA.

    See Public Notice, Rep. No. SAT-01404 (rel. July 26, 2019).

    Although the Commission by rule authorizes TT&C operations for GSO satellites during the orbit-raising
    phase, it has not yet adopted a similar rule for NGSO systems (though one is currently under consideration).
    See 47 C.F.R. § 25.282; Mitigation of Orbital Debris in the New Space Age, FCC 18-159, ¶ 70 (rel. Nov. 19,
    2018).

    SpaceX Services currently has applications pending for six Ku-band gateway earth stations (located in North
    Bend, WA; Conrad, MT; Merrillan, WI; Greenville, PA; Redmond, WA; and Hawthorne, CA) and one TT&C
    earth station (located in Brewster, WA). SpaceX Services received complementary STAs for these earth stations
    to communicate with the SpaceX NGSO satellites.


the Commission’s rules and Article 21 of the ITU Radio Regulations, which the Commission has
found sufficient to protect GSO systems and terrestrial systems, respectively, against harmful
interference. In the extremely unlikely event that harmful interference should occur due to
transmissions to or from its earth station, SpaceX will take all reasonable steps to eliminate the
interference. Should an issue arise, SpaceX can be reached at satellite-operators-
pager@spacex.com, which links to the pagers of appropriate technical personnel 24/7.
        Accordingly, SpaceX requests that the Commission extend the STA for these space stations
for up to an additional 30 days.
