SpaceX Starlink becomes first US mega-constellation to gain FCC approval

Published

on

Sans fanfare, the Federal Communications Commission (FCC) has made SpaceX the first US-based entity authorized to launch and operate a massive broadband internet satellite constellation in Low Earth Orbit (LEO).

The Starlink constellation authorization comes a bit less than five weeks after SpaceX launched its first two prototype communications satellites as co-passengers with the Spanish PAZ imaging satellite. CEO Elon Musk confirmed that they had safely made it to orbit and were communication with ground control in Hawthorne, CA, but SpaceX’s lips have remained sealed beyond Musk’s brief mention.

Unofficially, sources in the loop were told that Musk forwarded a memo to all hands soon after launch, confirming that the Starlink prototypes had successfully sent their “Hello, world” message to ground control. In the month since launch, the Tintin twins appear to have both raised their orbits slightly, suggesting that their propulsion systems were/are at least partially functional. Per FCC licenses for the experimental satellites, the Tintins are expected to eventually raise their orbits from 500km to approximately 1100km over the course of testing, maneuvering that would require their SpaceX-designed ion propulsion modules to function properly.

Gwynne Shotwell, COO of SpaceX, gave an official statement on the FCC’s authorization of Starlink, reiterating the company’s awareness of a huge amount of work ahead of any operational constellation.

“We appreciate the FCC’s thorough review and approval of SpaceX’s constellation license. Although we still have much to do with this complex undertaking, this is an important step toward SpaceX building a next-generation satellite network that can link the globe with reliable and affordable broadband service, especially reaching those who are not yet connected.”

As the SpaceX’s first foray into true electric propulsion and dedicated communications satellites, not to mention an array of cutting-edge technologies (optical/laser-based interlinks, advanced antenna tech, and more) presumed to be on board, it’s fair to assume that the public silence is indicative of a heads-down work ethic while Starlink engineers and technicians get a handle on the tasks before them and learn volumes about the manufacture and operation of advanced satellites. If they were to occur, failures or serious problems with these first two prototypes would, in fact, benefit SpaceX and strengthen all future prototype testing efforts, ultimately resulting in a more successful final product and happier customers in the long term.

Although the FCC’s approval carries with it a number of conditional requirements of SpaceX, it is all but guaranteed that SpaceX will be able to satisfy those conditions and ensure that Starlink remains authorized, barring any significant and unforeseen legal challenges. Of those conditions, the most significant condition of note relates to a request for additional information from SpaceX on the company’s end-of-life and deorbit practices in order to guarantee that the constellation’s 4,000+ satellites do not become a space debris risk. The most serious threat to Starlink as it stands proposed today is the FCC’s decision to deny SpaceX a waiver for the requirement that 50% of any given LEO internet constellation must be launched six years after approval. In the case of the 4400+ satellite Starlink constellation, this would require SpaceX to launch more than 30 satellites a month for every month between now and March of 2024. Thankfully, the FCC approval acknowledges that it will reconsider SpaceX’s request for a waiver of this requirement in the future, once the design of Starlink has been finalized. 

Correction: While the FCC’s final license grant appeared to deny a waiver requested by SpaceX for the requirement of launching 50% of the constellation within six years of licensing, the FCC has in fact already reconsidered this requirement [PDF] for uniquely large constellations out of its sheer impracticality. SpaceX should thus have some added flexibility in the pace of its deployment of Starlink.

Limited internet service from SpaceX’s Starlink constellation is not expected to begin before 2020 at the earliest. The FCC’s announcement can be read in the news release here [PDF]  or in the full application approval here [PDF].

SpaceX and Elon Musk explain potential reasons for Starship loss

SpaceX and its CEO Elon Musk are starting to shed some light on the potential reasoning for the loss of Starship yesterday, which was lost after a successful launch and catch of the lower-stage booster.

Starship was lost during its ascension, and debris rained down over the Caribbean less than an hour after SpaceX lost all communication with the spacecraft.

A few hours after the launch was over, SpaceX started to shed some light after looking at preliminary data that the rocket left behind.

The company said that a fire developed in the aft section of Starship:

“Following stage separation, the Starship upper stage successfully lit all six Raptor engines and performed its ascent burn to space. Prior to the burn’s completion, telemetry was lost with the vehicle after approximately eight and a half minutes of flight. Initial data indicates a fire developed in the aft section of the ship, leading to a rapid unscheduled disassembly with debris falling into the Atlantic Ocean within the predefined hazard areas.”

Additionally, Musk said that there was some sort of oxygen or fuel leak in the cavity above the ship engine firewall.

The leak was evidently large enough to build more pressure than the vent was able to handle:

Some also seemed to recognize evidence of fires throughout the flight of Starship, which is obviously an anomaly:

There will be more information regarding the loss of Starship in the coming days and weeks, but Musk already believes that a bit of fire suppression and more volume in the cavity above the ship engine firewall could fix the issue.

“Nothing so far suggests pushing next launch past next month,” he said, so Flight 8 could happen sometime in February.

SpaceX completes second catch of lower stage, but loses Starship

SpaceX completed its seventh launch of Starship on Thursday, accomplishing a clean liftoff and catch of the first-stage booster. However, the upper stage was lost after its ascent.

The launch took place just a few minutes after 5 p.m. on the East Coast, as the first attempts at getting Starship in the air for the seventh time were delayed by weather both last week and this week.

Conditions were favorable on Thursday as SpaceX looked to follow up a successful campaign by Blue Origin, Jeff Bezos’s company, earlier today.

SpaceX went into the seventh Starship launch with plans for a catch attempt of the first-stage booster, something it attempted and completed during the fifth test launch last year. It decided to skip a catch attempt with the sixth test flight as conditions were not aligned.

For now, SpaceX is extremely selective as to when it attempts catches.

However, it was successful during this attempt, its second completed catch:

This flight differed from previous launches as SpaceX rolled out several improvements to the rocket and the processes as it featured plans to do a Starlink deployment simulation and had various adjustments to flap placement and avionics.

These plans were disrupted by the fact that SpaceX lost all communications with Starship about ten minutes into the flight, which the aerospace company confirmed was a result of losing the spacecraft sometime during its ascent.

Although the catch was successful, the loss of the actual rocket seemed to be a huge damper on the entire event. SpaceX confirmed several minutes after the loss of communications that the rocket was destroyed and was lost.

It was its first failure since the second Starship launch in November 2023. SpaceX had no answers for why the rocket was destroyed and lost.

We will keep you updated in the coming days.

SpaceX confirms next Starship launch target – Here’s when it will take off

SpaceX has confirmed a new target date for the seventh Starship test launch after weather in Texas delayed the first scheduled date for “three or four days.”

The company is now targeting the launch for Monday, January 13, at 4 p.m. CST or 5 p.m. EST. The launch date is not set in stone as any variety of delays could impact this, but SpaceX hopes to finally take off after a delay that pushed it back from January 10.

What’s new with this Starship launch

With this being the seventh test launch of Starship, there are several things that the company will change and hope to accomplish. All of these launches are done in preparation for eventually taking flight to Mars, something that will happen next year, according to CEO Elon Musk.

First, SpaceX is rolling out a next-generation ship with “significant upgrades.” Forward flaps have been made smaller and are repositioned away from the heat shield, which will “reduce their exposure to reentry heating.”

SpaceX eyes 25 annual Starship launches starting next year

There is also a 25 percent increase in propellant volume, a new fuel feedline system for the Raptor vacuum engines, and a better-than-ever propulsion avionics module that will control the valves and reading sensors.

Avionics, as a whole, underwent a redesign and now have more capability and redundancy for missions as they become more complex.

Starlink test

SpaceX is also planning to deploy 10 Starlink simulators that are similar in size and weight to the next-generation Starlink satellites:

“While in space, Starship will deploy 10 Starlink simulators, similar in size and weight to next-generation Starlink satellites as the first exercise of a satellite deploy mission. The Starlink simulators will be on the same suborbital trajectory as Starship, with splashdown targeted in the Indian Ocean. A relight of a single Raptor engine while in space is also planned.”

Ship return and catch

There will be several experiments that have to do with returning Starship and various catch scenarios and sequences. One of which will see “a significant number of tiles be removed to stress-test vulnerable areas across the vehicle.”

The ship’s reentry profile was also intentionally designed to test the structural limits of the flaps while at the point of maximum dynamic pressure during reentry.

Currently, SpaceX did not detail whether it would attempt another catch during this test launch. These are usually game-time decisions.
