ESA selects Ariane-6’s first payloads

9:05 am

The European Space Agency (ESA), ArianeGroup, and Arianespace today announced the payloads that will fly on the first launch of its new Ariane-6 rocket.

The payloads are a variety of cubesats and science experiments, none heavier than 175 pounds with a total payload weight less than one ton. These secondary payloads will either be deployed from or kept attached to a dummy mass that will simulate a large primary satellite payload.

The press release makes no mention of a launch date, as has been the pattern in the last few Ariane-6 press releases. The last release to mention a launch date was in October 2020, which then predicted a launch in the second quarter of ’22. That this date is no longer being mentioned suggests the date has been pushed back, though for how long remains a mystery.

New Arianespace Vega-C rocket being prepared for first launch in April

9:22 am

Engineers in French Guiana are now preparing all the components of the first Vega-C rocket, built by the Italian company Avio, for its first launch in April.

Vega-C is an upgraded version of the Vega rocket and is currently set to launch no earlier than April 2022. The rocket will feature improved first and second stage solid rocket motors, an upgraded liquid-fueled AVUM+ upper stage, and usher in an era of propulsion system commonality between the Vega and Ariane rocket lines.

At the moment they are modifying the Vega launchpad and building a new mission control center. Once completed in March they will stack the rocket.

Vega-C, like its predecessor, is powered by solid rockets, which Avio believes can be competitive with reusable rockets, at least for the next decade or so. Arianespace also hopes to lower costs by using the exact same solid rocket boosters on both Vega-C and its new Ariane 6 rocket. Vega-C’s first stage, using a P120C solid rocket motor, is also used as side boosters on Ariane 6.

Ariane-6 finally wins more launch contracts

9:29 am

Arianespace today announced a new slew of launch contracts, including two for its mostly Italian-built Vega rocket family and four for its Ariane family of rockets.

The latter launch contract is significant as those four launches, putting eight more Galileo GPS-type satellites in orbit for the European Union over the next three years, will all be launched by Arianespace’s new Ariane-6 rocket, built and owned by the commercial company ArianeGroup.

The significance is twofold. First, Ariane-6 has struggled to get launch customers because its launch cost is far higher than SpaceX’s, to a point that the low number of contracts weren’t paying for the cost of development. This new contract overcomes that difficulty by adding four more launches.

Second, the nature of all of Ariane-6’s contracts underscore the difficulties it is having. Before the arrival of SpaceX’s mostly reusable and very inexpensive Falcon 9 rocket, Arianespace held 50% of the market share for commercial launch contracts, using its Ariane-5 rocket. Those customers have mostly vanished, however, switching to SpaceX. Ariane-6 was conceived — by the government-run European Space Agency — as a newer cheaper rocket that would recapture some of that market. All of its launch contracts, both old and new, demonstrate that it is failing to do so, however. Its only customers so far are coming from European government entities, who are required to use Ariane-6 as part of their partnership in the European Union and the European Space Agency. No private concern, inside or outside Europe, seems interested in using Ariane-6. It just costs too much.

For Europe to compete in the new commercial launch market it needs to build better rockets. And to do this it needs to release its rocket industry from the control of government.

Webb successfully launched

8:13 am

Early this morning an Ariane 5 rocket successfully launched the James Webb Space Telescope from French Guiana.

The key moment that indicated the launch was success was, after Webb was deployed from the rocket’s upper stage, its solar panels deployed and the telescope began receiving power from them.

The launch itself was something that has been done by the Ariane 5 rocket many many times, without failure. Now comes the part of this operation that has never been done before.

Now “30 days of terror” begin, as JWST starts its career in space. First, it will take the space telescope 30 days to reach the start of its halo orbit at L2. On its way, the telescope must unfurl its 18 gold-plated beryllium mirror segments using 132 actuators. It will also have to deploy its five-layer, origami sunshield and cool down to below 50K (-223°C or -370°F) to begin the start of science operations in 2022.

NASA has a webpage that shows the step-by-step deployment, and allows you to see the status at any time during the next 30 days.

After almost twenty years of development and a budget that went 20x over its original estimate, let’s us all hope that Webb deploys properly and begins collecting data as intended. If it does, it will allow astronomers to make ground-breaking discoveries, and we shall gain a better idea of what lies hidden behind that black sky that surrounds us.

As for the 2021 launch race, this is the updated leader board:

49 China
31 SpaceX
22 Russia
7 Europe (Arianespace)

China will likely be the winner in the national rankings, 49 to 48 over the U.S. This was the 130th successful launch in 2021, only the second time in the history of space exploration that the world reached that number of launches in a single year.

Webb telescope reaches launchpad on Ariane 5 + how to watch launch

9:14 am

The James Webb Space Telescope, stacked on top of Arianespace’s Ariane 5 rocket, has finally reached its launchpad in French Guiana after twenty years of development costing 20 times its original budget.

The launch itself is now scheduled for December 25, 2021 at 7:20 am (Eastern). It will be live streamed by both NASA (in English) and Arianespace (with options in English, French, or Spanish).

I have embedded below NASA’s feed. As always, expect NASA to pump you with lots of propaganda during its live stream.

When all is said and done, Webb has the chance to show us things about the universe we’ve never seen before. Optimized for deep space cosmology, it will provide us a window into the earliest moments of the universe’s existence. And is infrared capabilities will allow it to peer into many nearer places obscured by dust with a resolution unmatched by previous telescopes.

Keep your fingers crossed all goes as planned.

ESA delays Webb launch one day due to weather

8:41 am

The European Space Agency (ESA) announced late yesterday that, due to “adverse weather conditions” in French Guiana, it has delayed the launch of the James Webb Space Telescope on an Ariane 5 rocket one day to December 25th.

The announcement also stated that the final launch readiness review also approved the launch, though no update has yet been issued on the ground control communications problem that had caused a two day delay last week.

Meanwhile, this story and its headline encapsulates the terror I think many astronomers presently feel about this telescope:

Why Astronomers Are “Crying and Throwing Up Everywhere” Over the Upcoming Telescope Launch

The sense is one of helpless panic among astronomers who want to use Webb. They know it will do really cutting edge science, but they also know that many things can go wrong, and the history of the telescope (ten years late and 20x overbudget) will likely make replacing it impossible.

And many things can go wrong. Below is NASA’s video showing the telescope’s complex unfolding, step-by-step, after launch.

Webb launch confirmed for December 24, 2021

9:01 am

Ten years late and twenty times over budget the European Space Agency (ESA) yesterday confirmed that the launch of NASA’s infrared James Webb Space Telescope is now scheduled for December 24, 2021.

The ESA announcement is only a couple of sentences long, and does not mention if engineers had solved the intermittent ground communications issue with the telescope. Further tweets from ESA and NASA also said nothing about the communication issue.

A final readiness review is set for December 21st where a final launch decision will be made.

Webb launch delayed two days because of ground equipment issue

9:42 pm

After engineers at Arianespace’s French Guiana launch facility found an intermittent issue with ground equipment related to the Ariane 5 rocket launching the James Webb Space Telescope, it was decided to delay the launch two days to make sure the problem was resolved.

n a brief statement, NASA wrote on its website late Tuesday that the Webb team is “working a communications issue between the observatory and the launch vehicle system.”

Thomas Zurbuchen, associate administrator for NASA’s science mission directorate, said Tuesday that engineers found an “interface problem” in a system that communicates with Webb while it’s on top of the Ariane 5 rocket. “The way to think about it is it’s a ground support equipment thing,” Zurbuchen said Tuesday night in an interview with Spaceflight Now. “Basically, the data cables are dropping some frames.”

Technicians inside the Ariane 5 rocket’s final assembly building in Kourou have tried to diagnose the problem, but so far, haven’t been able to resolve it.

The December 24th target day date remains tentative, and could slip to December 25th, or even later, depending on how successful engineers are at fixing the issue.

Arianespace launches two Galileo GPS-type satellites

8:14 pm

Capitalism in space: Using a Russian Soyuz-2 rocket, Arianespace successfully launched two Galileo GPS-type satellites from its spaceport in French Guiana tonight.

The leaders in the 2021 launch race:

45 China
27 SpaceX
20 Russia
6 Europe (Arianespace)

China still leads the U.S. 45 to 42 in the national rankings. This launch tonight was 116th successful launch in 2021, which is the most launches completed in a year since 1988. Based on the number of planned launched over the next three weeks, there is an outside chance that the global total will top 127, making this the second most active year ever in the history of space. Even if the numbers end up in the mid-120s, 2021 will be among the top eight years ever.

And I expect next year to easily top this year.

Engineers: Webb undamaged by “incident”, ready for December 22nd launch

9:46 am

Arianespace engineers have confirmed after testing that the James Webb Space Telescope was undamaged by “incident” that occurred during stacking, and have okayed the resumption of the telescope’s preparation for launch.

On Wednesday, Nov. 24, engineering teams completed these tests, and a NASA-led anomaly review board concluded no observatory components were damaged in the incident. A “consent to fuel” review was held, and NASA gave approval to begin fueling the observatory. Fueling operations will begin Thursday, Nov. 25, and will take about 10 days.

The launch is now set for December 22nd.

Webb launch delayed four days because of “incident” during stacking

2:18 pm

NASA management has decided to delay the launch of the James Webb Space Telescope for four days while engineers investigate whether an “incident” that occurred during the telescope’s stacking on top of an Ariane 5 rocket could have long term consequences.

Technicians were preparing to attach Webb to the launch vehicle adapter, which is used to integrate the observatory with the upper stage of the Ariane 5 rocket. A sudden, unplanned release of a clamp band – which secures Webb to the launch vehicle adapter – caused a vibration throughout the observatory.

A NASA-led anomaly review board was immediately convened to investigate and instituted additional testing to determine with certainty the incident did not damage any components. NASA and its mission partners will provide an update when the testing is completed at the end of this week.

The launch had been scheduled for December 18th. They have now pushed it back to December 22nd.

Arianespace and Chinese launches this weekend

10:25 pm

Two launches occurred this weekend.

First Arianespace used its Ariane 5 rocket to place two communications satellites in orbit, one for the French military and the second for the commercial company SES. The total payload weight set a record for the rocket.

With this success the path is now clear for the launch of the James Webb Space Telescope on the next Ariane 5 launch in December.

Next the Chinese used its Long March 3B rocket to launch a technology test satellite aimed at testing “space debris mitigation technologies.” No other information was released.

The leaders in the 2021 launch race:

37 China
23 SpaceX
17 Russia
4 Northrop Grumman
4 ULA
4 Arianespace (Europe)

China now leads the U.S. 37 to 36 in the national rankings.

Next Ariane 5 launch postponed

11:39 am

Arianespace today announced that it has postponed its next Ariane 5 launch of two communications satellites, scheduled for October 22nd, because of issues with ground equipment.

Though there appear to be no issues with the rocket, this delay could effect the launch of the James Webb Space Telescope in December on another Ariane 5 rocket. Arianespace has said that it wants to complete this launch first, to make sure the fixes it completed on the rocket’s fairing are truly working.

It was those problems that shut down all Ariane 5 launches for almost a full year.

No new launch date has been set. Normally, ground equipment issues cause short delays, so we should be hopeful all will be fixed quickly and this launch will be quickly rescheduled and take off without problems.

Webb telescope finally arrives at launch site in French Guiana

2:54 pm

Webb deployment

After almost twenty years of construction (a decade behind schedule) and a cost of $10 billion, ($9.5 billion over budget), the James Webb Space Telescope today arrived at the processing facility at Arianespace’s French Guiana spaceport, where it will be prepared for a December 18, 2021 launch on an Ariane 5 rocket.

Once launched the telescope, which is not a replacement for Hubble because it observes in the infrared (not optical) and is optimized for deep space cosmology, will take two weeks to reach its orbital position about a million miles from Earth, as shown in the graphic.

Let us all cross our fingers and toes that it all works as designed, for if it doesn’t this will be the biggest failure ever in the history of NASA.

Italy switches from Arianespace to SpaceX for launch contract

9:05 am

Capitalism in space: Because of the two recent launch failures of Arianespace’s Vega rocket (built mostly in Italy), the Italian space agency (ASI) has decided to take the launch of an Earth observation satellite from Arianespace and award the launch contract instead to SpaceX.

The article at the link describes in detail the history and politics that make this decision significant. Essentially, because Arianespace in the past decade has failed to meet the challenge of SpaceX, so that its launches continue to be more expensive, this government-subsidized business has tried to force nations in the European Space Agency (ESA) to use Arianespace rockets via political agreements.

With this decision Italy is defying that pressure, which in turn is going to increase the pressure on Arianespace to finally step up its game, or die from lack of business. For example, when the ESA agreed to have Arianespace build its next generation rocket, the Ariane 6, it failed to require it to be reuseable. The Ariane 6 rocket was therefore designed as an expendable rocket, which meant that right from the start it could not compete with SpaceX’s Falcon 9. It has therefore failed to win launch contracts.

Expect the Ariane 6 to continue to fade as the years pass, simply because the bureaucrats in ESA and Arianespace refused to take their competition seriously.

Arianespace successfully completes first Ariane 5 launch in almost a year

11:23 pm

Arianespace today successfully completed its first Ariane 5 launch since August 2020, placing in orbit two commercial communications satellites.

The long gap in launches occurred because of a vibration issue discovered during that August 2020 launch durng the release of the rocket’s two fairing halves.

Engineers introduced modifications to the Ariane 5’s payload fairing, or nose cone, to reduce vibrations imparted on the satellites during separation of the shroud, which protects payloads during the first few minutes of flight through the atmosphere. Ground teams will analyze data from the rocket to make sure the changes reduced the vibrations.

Another launch is scheduled for September, followed next by the launch of the James Webb Space Telescope in either November or December. The results from today’s launch as well as the one in September will determine if the Webb launch will go forward on time.

These issues with Ariane 5, delays imposed by the company in fear of the Wuhan flu, and other launch problems with Arianespace’s Vega rocket, has meant that this is only its second launch in 2021, a pace that is below its pace for most of the last decade. Whether the company can recover and pick up the pace before the end of the year will depend on what they learn during today’s launch.

With only two launches total, Europe’s Arianespace remains off the leader board in the 2021 launch race:

24 China
20 SpaceX
12 Russia
3 Northrop Grumman
3 Rocket Lab

The U.S. lead over China in the national rankings remains 30 to 24.

Ariane 6 inaugural launch date appears to be delayed again

9:46 am

It appears that officials at the European Space Agency (ESA) have begun preparing the public for a further delay in the first launch of its new Ariane 6 rocket, from the second quarter of 2022, as announced in October 2020, to the third quarter of 2022, at the earliest.

Josef Aschbacher, director general of the European Space Agency, at the Paris Air Forum [described the creation of] “a small group” … to make an independent assessment of the schedule for the final development phase of the Ariane 6 rocket. The goal of this task force will be to ensure that Europe does everything it needs to do launch on time.

…In referring to an “on time” launch, Aschbacher said he meant next year, before the European Space Agency’s Ministerial Council meeting that is typically held in October or November. This is a high-level meeting where representatives from each member nation of the space agency gather to set policy. The European Space Agency’s budget is provided, in varying amounts, by member nations. “This is a must,” Aschbacher said of launching before the 2022 meeting, “because we need good news, and good success, for our politicians to see that Europe performs, that Europe delivers, and therefore it is worth investing in space in the ministerial conference.”

It appears from these statements that the development of Ariane 6 is now faced with delays that might make a launch by the third quarter in ’22 difficult, and this new independent committee is being put together to try to forestall that possibility. What makes this even more significant for Ariane 6 is that it continues to have trouble winning contracts from the nations within ESA, as it remains far more expensive that SpaceX’s Falcon 9. If that first launch is delayed past that important fall ’22 high-level meeting, those politicians at that meeting might decide to consider serious new alternatives to it, or even more drastically decide to replace it entirely.

Problem with Ariane 5 rocket causes Arianespace to delay Webb telescope launch

9:08 am

As first revealed in mid-May, Arianespace has been forced to delay the launch of the James Webb Space Telescope by at least one month because of a problem with the fairing on its Ariane 5 rocket, found during an August 2020 launch.

There have been no Ariane 5 launches since. According to yesterday’s press briefing, however:

“The origin of the problem has been found. Corrective actions have been taken,” Daniel de Chambure, acting head of Ariane 5 adaptations and future missions at ESA, said. “The qualification review has started, so we should be able to confirm all that within a few days or weeks.” He did not elaborate on the problem or those corrective actions, beyond stating that the problem took place during separation of the payload fairing. Industry sources said in May that, on the two launches, the separation system imparted vibrations on the payload above acceptable limits, but did not damage the payloads.

It appears this new delay to Webb’s launch is because two commercial payloads must lift off first before Webb, with the first now scheduled for July. According to Arianespace, it will take two months prep for the next commercial launch, followed by two months prep for the Webb launch. That puts the launch of Webb in November.

Overall this particular delay is slight, only a few weeks, and pales in comparison to the ten years of delays experienced by NASA during development and construction of Webb. It also will add very little to the telescope’s overall budget, which has grown from an original price of $500 million to now about $10 billion.

More delays for Webb telescope?

8:53 am

An issue with the fairing release on the last two Ariane 5 launches has not only paused use of that rocket since August 2020, it might cause another delay in the planned October 31, 2021 launch of the James Webb Space Telescope.

In a statement to SpaceNews, Arianespace acknowledged that “post-flight analyses conducted on two recent Ariane 5 launches have indicated the occurrence of a less than fully nominal separation of the fairing, however with no adverse impact on the Ariane 5 flights in question.”

The company did not elaborate on the problem, but industry sources familiar with the issue said that, on both the August 2020 launch and the previous Ariane launch in February 2020, the separation of the faring induced vibrations into the payload stack well above acceptable limits. Neither incident damaged any of the payloads, but raised concerns about the effect on future missions, including JWST.

Moreover, Arianespace has two Ariane 5 launches on its schedule that are supposed to launch before Webb. If those are delayed it puts a further squeeze on the Webb launch date.

Meanwhile, the final checkouts of the Webb telescope have been proceeding, including a successful test of the unfolding of the telescope’s segmented mirror.

After a more than decade of delays and budget overruns — raising this telescope’s budget from 1/2 billion to $10 billion — it appears that Webb’s final schedule delay might occur not because of the telescope but because of the rocket.

In addition, the issue at Arianespace appears to be seriously impacting that company’s ’21 launch schedule, having failed to launch any Ariane 5 rockets so far this year.

Arianespace’s Vega rocket launches six satellites

8:52 am

Arianespace yesterday successfully completed its first Vega rocket lift-off since a launch failure last year, placing six satellites in orbit.

This was Arianespace’s first launch in 2021. Though the year is still early, the timing of this launch, late April, puts them well behind the pace they have set for most of the 21st century.

The leader board for the 2021 launch race remains unchanged:

12 SpaceX
10 China
7 Russia
2 Rocket Lab

The U.S. still leads China 17 to 10 in the national rankings.

ESA confirms cause of November Vega launch failure

9:09 am

The European Space Agengy (ESA) has now completed its full investigation of a Vega rocket launch failure in November, and confirmed that the initially announced cause of “human error” was correct.

Engineers had installed cables backwards causing the nozzle in the upper stage to go one way when it should have gone the other.

The press release at the link is a wonder of bureaucratic cover-your-behind gobbly-gook, saying much without providing any concrete information about the corrections imposed. For example, the upper stage structure is built by one company, Airbus, the engine is built by two Russian companies, Yuzhnoye and Yuzhmash, while a fourth company, Avio, supervises the stage’s assembly. The press release makes it a point to not tell us where the error was made by which company, though by vague implication it suggests the error occurred during final assembly by Avio.

If I was a satellite company thinking of buying a Vega launch I would demand a much more straight-forward explanation. Otherwise I’d go elsewhere.

German smallsat startup raises $91 million for new rocket

9:36 am

Capitalism in space: A German startup, dubbed Isar Aerospace, has successfully raised $91 million in private investment capital to finance design and construction of a new rocket aimed at launching smallsats.

It plans to use the money to continue its research, development and production en route to its first commercial launches, planned for early 2022. The launcher is not just significant for its design innovation, but if it proves successful, it would make Isar the first European space company to build a successful satellite launcher to compete in the global satellite market.

The round, a Series B, is being led by Lakestar, with significant contributions also from Earlybird and Vsquared Ventures; additional funding from existing investors like Airbus Ventures, former SpaceX Vice President Bulent Altan, Christian Angermayer’s Apeiron, and UVC; and also new investors HV Capital and Ann-Kristin and Paul Achleitner are also joining the round.

Earlybird and Airbus Ventures led Isar’s previous round of $17 million in December 2019.

There are a lot of such startups right now, the majority of which I expect to fall by the wayside, especially the latecomers. What makes this particular story interesting is that it describes a European company. So far there has not been much activity in the new launch market coming from independent European companies. With the government-run Arianespace dominating the market, it is difficult for private companies to gain a foothold.

This might be changing because of the failure of Arianespace’s Ariane 6 to successfully compete on price with SpaceX, a failure that gives new companies an opening to gain some market share in Europe. The two recent launch failures of Arianespace’s smaller Vega rocket likely helps that new competition as well. Isar’s funding success here might be indicating this.

Arianespace: Cause of Vega launch failure “human error”

10:18 pm

According to Arianespace officials, today’s failure of their Vega rocket likely occurred because of “human error” in the installation of cables.

Engineers concluded that cables leading to thrust vector control actuators on the upper stage were inverted, apparently a mistake from the assembly of the upper stage engine, according to Roland Lagier, Arianespace’s chief technical officer. The thrust vector control system pivots the upper stage engine nozzle to direct thrust, allowing the rocket to control its orientation and steering.

The cabling problem caused the engine to move its nozzle in the wrong direction in response to commands from the rocket’s guidance system. That resulted in the rocket losing control and tumbling just after ignition of the upper stage engine around eight minutes after launch.

Lagier characterized the inverted cables as a “human error,” and not a design problem.

The next obvious question is the source of the error. The answer was not revealed, I think partly because of the number of contractors involved in building that upper stage:

The AVUM upper stage’s structure is produced by Airbus, and the Ukrainian rocket contractors Yuzhnoye and Yuzhmash supply the AVUM stage’s main engine, which consumes hydrazine and nitrogen tetroxide propellants. Avio, the Vega rocket’s Italian prime contractor, oversees final integration of the AVUM upper stage.

The goal of the investigation that will now follow will be to point that source among these contracts, and how their interaction might have contributed to it.

Arianespace’s Vega rocket fails again at launch

8:55 am

Early today Arianespace’s Vega rocket failed, for the second time in its last three launches, to put two satellites into orbit.

A liquid-fueled upper stage — known as the Attitude and Vernier Upper Module, or AVUM — was supposed to fire four times Monday night to place the Spanish SEOSAT-Ingenio Earth observation satellite and the Taranis research spacecraft from the French space agency CNES into slightly different orbits at an altitude of roughly 420 miles (676 kilometers) .

But something went wrong just after the first ignition of the AVUM fourth stage. “After the first nominal ignition of the last stage engine, an anomaly has occurred, which caused a trajectory deviation entailing the loss of the mission,” said Avio, the Vega rocket’s Italian prime contractor, in a statement. “Data analyses are in progress to determine the causes.”

This is bad new for Europe’s space effort. It will likely but a crimp in the development of their two next generation rockets, the Ariane 6 and the Vega-C, as the upper stage that failed involves all the contractors building those rockets, Airbus and Avio.

The failure of this particular engine also badly damages the future of the two Ukrainian contractors, Yuzhnoye and Yuzhmash, who built it. They have lost all business with Russia because of the war between those two countries, and now have this failure to darken their resume with the rest of the world.

OneWeb announces new launch schedule, cancels Ariane 6 launch

9:47 am

Capitalism in space: OneWeb, as it restructures itself after its purchase by a partnership of an Indian company and the UK government, has announced a new launch schedule for completing its satellite communications constellation by 2022, with the first launch in December.

The key change is that they have cancelled their deal to fly OneWeb satellites on the first launch of Arianespace’s Ariane 6 rocket. From the first link:

Arianespace will conduct 16 Soyuz launches for OneWeb, each carrying 34-36 satellites, to complete OneWeb’s internet megaconstellation by the end of 2022. The revised contract canceled two Soyuz launches, and removed OneWeb as the customer for the inaugural Ariane 6 launch, an Arianespace spokesperson told SpaceNews.

The Ariane 6 cancellation is bad news for Arianespace’s new rocket, which has had trouble garnering customers. I am sure OneWeb was offered a great price to launch some satellites on that inaugural flight, and still OneWeb backed out.

For Russia this announcement is good news, even if they have lost two Soyuz launches. It means the bulk of their Soyuz launches will go forward, pumping money into the Russia’s starving commercial launch industry. This launch contract is essentially the only Russian commercial contract, with SpaceX stealing all of Russia’s former customers, and the bankruptcy had threatened it.

Finally, this announcement shows that OneWeb’s new owners have recognized that they have to get their satellites launched as fast as possible if they are going to compete with SpaceX’s Starlink constellation.
