Progress docks with ISS

As expected a Russian Progress freighter docked with ISS yesterday, on schedule and with no mishaps.

I report this non-news story simply because of the Russian claim yesterday that a SpaceX Starlink satellite and Falcon 9 upper stage threatened a collision with that freighter as it maneuvered in orbit prior to docking.

Not surprisingly, there was no collision. The Russians knew this, or they would never have launched as they did. They made a stink about it as a ploy to stain SpaceX, a company that has taken almost all their commercial launch business by offering cheaper and more reliable rockets.

Russia: Progress freighter and SpaceX rocket/satellite to have near miss

According to a Russia news outlet, their just launched Progress freighter will have a near miss today prior to its docking with ISS with two SpaceX objects, a Falcon 9 upper stage and a decommissioned Starlink satellite.

The Progress spacecraft, which carries about 3,600 lbs. (1,633 kilograms) of cargo including food, fuel and other supplies to the orbital outpost, launched from Roscomos’ Baikonur cosmodrome in Kazakhstan at 7:27 p.m. EDT (2327 GMT) on Tuesday (June 29). Progress 78 will approach the two objects about three and a half hours before its docking at the International Space Station, which is scheduled for 9:02 p.m. EDT on July 1 (0102 July 2 GMT).

The close approach, which triggered a potential collision alert, was detected by the Roscosmos TsNIIMash Main Information and Analytical Center of the Automated System for Warning of Hazardous Situations in Near-Earth Space (ASPOS OKP), Roscosmos said in the statement issued on the space agency’s website Wednesday (June 30) at 7:47 a.m. EDT (1147 GMT).

Based on preliminary calculations, the Starlink 1691 satellite will be just 0.9 miles (1.5 kilometers) away from Progress 78 on Thursday (July 1) at 5:32 p.m. EDT (2132 GMT). Three minutes later, a fragment of a Falcon 9 rocket booster left in orbit in 2020 is expected to approach the spaceship within 0.3 miles (500 meters).

Based on that timetable, the near miss has already occurred. No word yet on whether there were any issues.

What is interesting is that Russia should have known this prior to launch. It is routine procedure to consider known orbital objects in scheduling liftoffs. Either they knew and decided to purposely fly this close for political reasons (it allows them to slam SpaceX while also touting the dangers of space junk) or had not done their due diligence before launch.

OneWeb signs deal with BT, Britain’s biggest telecommunications company

Capitalism in space: OneWeb has signed a deal with BT (formerly British Telecom) where BT will test the use of OneWeb’s satellites to provide internet to remote regions in Great Britain.

The tie-up with Oneweb will come as a major boost to BT as it ramps up its efforts to roll out full-fibre broadband across the country. The telecoms giant recently hiked its target to 25m premises by the end of 2026. However, BT has previously warned that regulatory hurdles and geographic challenges could slow down the project. The companies said they would explore how a partnership could boost capacity, mobile resilience, backhaul and coverage in remote locations.

This means that OneWeb and SpaceX’s Starlink are now in direct competition for customers in the rural areas of Great Britain. While a Starlink customer uses their own dish to communicate directly to the SpaceX satellite constellation, OneWeb is designed to have many nearby customers first link via a ground network to a much larger single dish, in this case something that BT would provide, which will then send the data to the satellite constellation.

I have no idea which design is better. For customers however the existence of two options is great, and will guarantee better service and lower prices.

Some Starlink units shut down if weather gets too hot

Capitalism in space: Some users of SpaceX’s Starlink internet dishes have found that the units shut down if the local weather gets too hot.

The units presently being distributed to customers are beta units, designed to test the system before SpaceX rolls out full commercial availability, so finding such issues is not unexpected. According to one engineer quoted at the link,

Engineers could change Dishy’s mechanical design to achieve better heat rejection, change the dish’s electrical components to expand its thermal operating window, or develop a feature that allows Dishy’s components to operate at reduced power to create less heat. He noted the latter two options would likely be taller orders. “If changes to Dishy’s mechanical design are insufficient to reject heat at a rate exceeding its ability to produce it, software changes will be required to make the system more thermally efficient,” Keiter said. “But if speed limiting and system optimization can’t fix the issue, it will require a significant hardware revision for the commercial launch.”

“Since they’ve got a lot of custom silicon in there—likely the limiting factor—the turnaround time on this would be very slow,” he added. “They could resort to some form of active heat removal like fans or thermoelectric cooling, but then they burn a ton of power which would make Dishy even more power hungry than it already is.”

“This is a really tricky engineering problem with some insanely tight constraints,” Keiter said. “The good news is that the team is pretty sharp.”

China creates company to build mega-satellite constellation

The new colonial movement: Late last month China officially created a company to build its own mega-satellite constellation, consisting of 13,000 satellites to provide internet access globally, to compete with the commercial constellations being built by SpaceX, OneWeb, and (someday) Amazon.

Spectrum allocation filings submitted to the International Telecommunication Union (ITU) by China in September last year revealed plans to construct two similarly named “GW” [Guowang] low Earth orbit constellations totaling 12,992 satellites. The filings indicate plans for GW to consist of sub-constellations ranging from 500-1,145 kilometers in altitude with inclinations between 30-85 degrees. The satellites would operate across a range of frequency bands.

Currently no details have been released on the contractors to be involved in the constellation. Notably the China Satellite Network Group will exist independent from and parallel to China’s main space contractors, the China Aerospace Science and Technology Corp. (CASC), and the China Aerospace Science and Industry Corporation (CASIC).

The apparent independence of China Satellite Network Group from CASC and CASIC indicates that other actors, such as other state-owned enterprises and commercial sector space companies could be involved in the construction of the constellation.

Not only does the creation of this company suggest a power-struggle within China’s government, it illustrates the intensifying competition internationally over space. While commercial satellite constellations like SpaceX and OneWeb will be able to provide their services to China, they will also be outside the control of that nation’s dictatorship. If their citizens use them they will have free access to information, something that China’s leaders refuse to allow.

Thus, the political decision in China to build their own constellation. It will also give China the ability to exert its influence worldwide by offering an alternative to the commercial western constellations, one that other dictators can control as well.

Expect more whining from astronomers about how this constellation of satellites will add to their woes. Instead of whining, might they finally decide to at last consider building in-space telescopes, where there is no atmosphere to fog their view and no satellites blocking their vision?

SpaceX successfully launches another 60 Starlink satellites

Capitalism in space: SpaceX today successfully used its Falcon 9 rocket to place another sixty Starlink satellites in orbit, bringing that constellation to over 1,700 in orbit.

The first stage was making its second flight, and landed successfully on the drone ship in the Atlantic. Both fairings were reused, with one making a record fifth flight. Though the rocket has not yet deployed the satellites as I write this, it is expected in about a half hour and based on past history, should proceed with no problems. If there is an issue I will report it immediately.

The leaders in the 2021 launch race:

16 SpaceX
13 China
7 Russia
2 Rocket Lab
2 ULA

The U.S. now leads China 22 to 13 in the national rankings.

Viasat asks FCC to block further launches of SpaceX’s Starlink satellites

Capitalism in space? The geosynchronous communications satellite company Viasat has demanded the FCC freeze any further launches of SpaceX’s quickly growing constellation of Starlink satellites.

The company claims a recent modification of SpaceX’s FCC license should not have been granted without a new environmental review of the 4,000+ satellite constellation’s impact.

Viasat is asking the FCC to hit pause on further launches until federal courts can review the legality of the license modification.

Carlsbad, California-based Viasat, which provides broadband services from geostationary orbit (GEO), had petitioned the FCC to conduct an environmental review before granting the license modification as part of the National Environmental Policy Act (NEPA), which currently categorically exempts satellite systems, but says this did not happen despite megaconstellations bringing new considerations for regulators.

Some astronomers had also requested an environmental assessment, worried about how the constellation’s reflectivity affects ground-based telescope observations.

What is really happening here is that Viasat, having discovered its market share is seriously threatened by a competitor, is trying to use the government to squelch that competition. Viasat doesn’t really give a twit about the environmental issues. It is launching its own new three-satellite geosynchronous constellation next year to provide broadband services globally, and Starlink’s success threatens to cut into its profits.

The article also reveals one interesting tidbit about former NASA administrator Jim Bridenstine. During his short three-year tenure heading NASA he aggressively moved to encourage provide competition and private enterprise by transferring the design, construction, and ownership of rockets and spaceships from NASA to the commercial sector.

Now that he is out of the government however he — like most Washington swamp creatures — has discovered his true calling: using his influence to squelch private competition:

In April, former NASA administrator Jim Bridenstine joined Viasat’s board of directors. Bridenstine told SpaceNews in an interview at the time that the threat of megaconstellations to space safety, and the overall space access environment, were among issues on his radar.

Like a ventriloquist’s dummy, Bridenstine upon leaving NASA immediately began mouthing the manufactured concerns of his new patrons at Viasat. To hell with allowing real competition and freedom. It is much more important to manipulate the power of the government to prevent Viasat’s competitors from succeeding. And earn a nice big salary at the same time.

SpaceX launches 60 more Starlink satellites; China launches Tianhe station module

Twas a busy evening. SpaceX successfully put 60 more Starlink satellites into orbit using its Falcon 9 rocket, with the first stage successfully completing its seventh flight, landing safely on the drone ship in the Atlantic.

China in turn successfully used its Long March 5B rocket to place in orbit the core module, dubbed Tianhe, of its planned space station. This is the first of eleven launches in the next two years to assemble the station’s initial configuration, including cargo and manned missions along the way.

The SpaceX live stream is at the link. I have embedded China’s English language live stream of the Tianhe launch below the fold. The launch is about 52 minutes in.

SpaceX raises another $1.16 billion in private capital

Capitalism in space: In a regulatory filing yesterday SpaceX revealed that it raised another $1.16 billion in private investment capital in just the past two months.

This follows two other recent financing rounds since August of last year in which SpaceX raised almost $3 billion. That makes $4 billion raised in eight months. All told, I think this brings the total private investment capital SpaceX has raised in the past two years to approximately $6 billion, all for building both the Starlink satellite constellation and the Starship/Superheavy rocket.

Not only does this give SpaceX ample cash to build both, it signals the growing faith big money investors have in the company’s plans. They have bought into Elon Musk’s dreams because he has proven that his dreams deliver, not only in exciting space ventures but in profits.

This fund-raising success also tells us that even if Starship does not reach orbit before SLS, it will very soon eclipse it entirely. It has the money now to get built, and the way SpaceX builds things, it will get built fast.
