FCC approves SpaceX’s Starlink constellation

Capitalism in space: The FCC has approved SpaceX’s revised plan for its Starlink satellite constellation designed to provide global internet access.

SpaceX already had authorization for 4,425 Starlink satellites that would use Ku- and Ka-band radio spectrum to beam internet data, but last November, the company asked the FCC to sign off on a plan that would put more than a third of the satellites in 550-kilometer-high (340-mile-high) orbits rather than the previously approved 1,150-kilometer (715-mile) orbits.

Eventually, SpaceX plans to add another wave of more than 7,500 satellites in even lower orbits to enhance the constellation’s coverage.

They hope to begin launching their first set of satellites by May, and begin commercial operations as early as 2021.

SpaceX raises a half billion for its Starlink satellite constellation

Capitalism in space: SpaceX has raised $500 million in investment capital to help fund its planned Starlink internet constellation expected to have just under 12,000 satellites in orbit.

I wonder if SpaceX will also be using this money for the development of Super Heavy/Starship. The article implies no, but the article also does not have access to the specific terms of the deal.

I also notice the interesting timing of this story today and yesterday’s story about how the Starlink satellites pose a threat of hitting people when they get de-orbited. Timing like this is rarely an accident. There are a lot of competitors to SpaceX who do not want it to succeed, and it would not surprise me if they are trying to throw a wrench in the operation to stop Starlink. A bad report like yesterday’s might cause big investors to back out.

FCC: SpaceX’s Starlink satellites can kill

The sky is falling! The FCC has calculated that fragments from SpaceX’s planned Starlink constellation of almost 12,000 satellites pose a risk of landing on humans on Earth.

SpaceX estimates that several kilograms of each 386-kilogram Starlink could reach the Earth’s surface with sufficient energy to harm or kill someone. NASA has fixed this figure at 15 joules—about the same wallop as a baseball traveling at 51 kilometers per hour. Depending on the satellite’s configuration, iron thruster components, stainless steel reaction wheels, or silicon carbide mirrors could survive the journey from orbit to your head.

…In March and June 2017, the FCC calculated the aggregate risk to humans from the entire constellation. Assuming the 11,927 satellites are launched on a regular basis, they will fail in the same way. Starting around six years from the first launch, an average of five satellites a day will reenter the Earth’s atmosphere, each with a tiny chance of failing to completely burn up, resulting in a part that could hit someone.

But with more than a thousand satellites falling a year, those tiny risks add up. The FCC figured out that, over their lifetime, satellites in the LEO shells posed a 1 in 5 risk of hurting or killing someone, and the VLEO satellites carried a 1 in 4 risk. IEEE Spectrum’s calculations using SpaceX’s most up-to-date information suggests that the overall risk of debris from the constellation causing an injury or death will be 45 percent.

Rather than demanding that we restrict or change what SpaceX does, I see this as an opportunity for someone designing robot satellites designed to clean up space junk. Offer your services to SpaceX. They get their problem solved easily, and you make some money.

Shake-up in SpaceX’s Starlink satellite division

Capitalism in space: It appears that Elon Musk has done a major shake-up in SpaceX’s Starlink satellite division, firing a number of managers because he was unsatisfied with the slow pace of development.

The management shakeup followed in-fighting over pressure from Musk to speed up satellite testing schedules, one of the sources said. SpaceX’s Behrend offered no comment on the matter.

Culture was also a challenge for recent hires, a second source said. A number of the managers had been hired from nearby technology giant Microsoft, where workers were more accustomed to longer development schedules than Musk’s famously short deadlines. Another senior manager that left SpaceX was Kim Schulze, who was previously a development manager at Microsoft, one of the people said. Schulze did not respond to a request for comment.

“Rajeev wanted three more iterations of test satellites,” one of the sources said. “Elon thinks we can do the job with cheaper and simpler satellites, sooner.”

A billionaire and Chief Executive Officer of Tesla Inc, Musk is known for ambitious projects ranging from auto electrification and rocket-building to high-speed transit tunnels.

Musk’s desire for speed here actually makes very good economic sense. There are other companies developing similar internet satellite constellations, and if SpaceX’s launches late they will likely lose a significant market share.

His concern about the slow pace seems to me also justified. This technology, while cutting edge, shouldn’t require as much testing and prototype work as it appears the fired managers wanted. Better to get something working and launched and making money, introducing upgrades as you go, as SpaceX has done so successfully with its Falcon 9 rocket.

FCC approves SpaceX 4K+ satellite constellation with strict new requirements

Capitalism in space: The FCC today approved SpaceX proposed gigantic 4,425 Starlink satellite constellation, designed to provide internet access worldwide, while also imposing a deadline for its launch and requiring the company to provide detailed de-orbit plans.

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.

SpaceX said the FCC’s deadline was “impractical” and that it could start broadband service without the full constellation. The FCC said no, but gave SpaceX permission to re-submit a waiver request in the future. SpaceX said in October it plans to start service with 800 to 900 satellites.

SpaceX’s constellation is the largest of all the applicants, generating concern about its potential to enshroud the Earth in a cloud of space debris. Fleet operators OneWeb, Spire, SES and Space Norway all expressed concern about how SpaceX will protect the space environment when operating so many satellites. But weighing more heavily with the FCC was NASA, which said a constellation as large as SpaceX’s likely needs to meet more stringent standards than what NASA recommends for de-orbit reliability. NASA’s reliability standard is that at least 90 percent of satellites can deorbit properly after their mission is complete.

The FCC did say that SpaceX will have the right in the future to request a waiver on the launch deadline.
