FCC Starlink approvals just keep coming. It's almost as if govt. agencies need it for something...

SpaceX gets OK to re-space Starlink orbits

WASHINGTON  The U.S. Federal Communications Commission approved SpaceX's request to increase the number of lanes its Starlink satellites can orbit, a modification the company said would accelerate service rollout across the United States. 

The FCC said SpaceX can field satellites in 72 rings around the Earth at 550 kilometers -  three times as many as the commission approved in April. 
>
In August, SpaceX told the FCC that by tripling the number of lanes for those first Starlink satellites, it could build out enough coverage to offer internet access in southern states by the 2020 hurricane season. 
>
SpaceX is building out Starlink from the poles, with coverage expanding towards the equator as more satellites get launched. 
>
SpaceX said the Starlink orbit modifications could cut the number of Starlink launches necessary by up to 50%. Under the revised plans, each of the 72 orbital rings will have 22 satellites instead of 66, meaning a single Falcon 9 launch can now populate approximately three rings. The company has been launching 60 satellites at a time on its Falcon 9 rockets. The next Starlink mission, and SpaceXs last launch of the year, is planned for late December.

20 in the 550km group, 40 in the lower group, and the deployment rods are on the way down.  Looks like their Hall thrusters work.

In case you missed it, first launch for the year. This guy amazes me!

4 more launches to a basic  upper US & Canadian Starlink service.

Do we know what their current bottleneck is? 

 

Is it satellite production, second stage production, launch options, money, system testing, etc.

 

Also will they be able to launch starlink from both Vandy and Kennedy?

They have $billions banked, and can get more just by asking. About every major venture capital or sovereign fund on Earth would buy into SpaceX given the chance.  Their last 2 rounds they had more offers than funding  needs.

 

SpaceX is running a satellite mass production line fast enough to support launching 120+ birds/month, and can modify those sat busses for other tasks. Watch that in the future.

 

Because reuse has worked so well they've also been able to switch much first stage production capacity into upper stage production.

 

Bottleneck: user terminal mass production.

 

Basically; an enclosed 30cm ± multi-beam phased array antenna with a 2-axis self-aligning base which can be fastened to a structure, plugged in and turned on for $300-500.

 

They'll need about 1 million, for starts. The patent is public, production is the issue.

The vast majority of Starlink will go up from the Cape due to it now having a polar launch corridor for vehicles with Autonomous Flight Safety Systems; F9, FH, Starship, New Glenn.

 

ULA won't fly an AFSS until Vulcan-Centaur arrives. Rocket Lab's Electron will fly AFSS from Wallops. 

 

Vandenberg SLC-4E will mostly do military, SpaceX SmallSat Rideshare Program and a few other polar launches.

US Air Force and US Space Force could be major Starlink profit centers, and a bit of regulatory grease.
