FCC approves SpaceX constellation, denies waiver for easier deployment deadline

SpaceX will have to launch at least half of its constellation of Ku- and Ka-band satellites within six years of today,
per the agency’s recently revised rules,
or its authorization freezes at the number of satellites in operation at that date.
The FCC in September relaxed its deadline, giving operators nine years
to launch their full constellation, but even those rules are stricter than what SpaceX would refer.
The launch-provider-turned-satellite operator asked the FCC for an okay to launch 1,600 satellites in six years
— just over a third of its full constellation.

展開期限の制約の他，スペースデブリの懸念もある．
