South Korea signs the Artemis Accords

9:15 am

On May 24 South Korea officially signed the Artemis Accords, joining nine other countries in the agreement designed as a work around of the Outer Space Treaty’s provisions in order to protect property rights in space.

By my count, that makes eight signatories, including Japan, United Kingdom, Australia, Canada, Luxembourg, the United Arab Emirates and Italy.

Essentially, the space-faring nations of the world are splitting into two groups, those who will follow these accords, and those who won’t, led by China and Russia. In a sense, we are seeing a renewal of the Cold War in space, with the western powers that believe in private enterprise and freedom aligned against those whose cultures are authoritarian and ruled from above.

Roscosmos finally approves ISS module Nauka for launch

9:10 am

After successfully completing its last ground tests, Roscosmos announced today that it has finally approved the launch on July 15th of its next module for ISS, dubbed Nauka.

Nauka’s long road to space began more than a quarter of a century ago, in 1995, with this year’s launch about fourteen years behind schedule. An engineer who started working on Nauka after graduation at the age of 25 would now be a grizzled veteran of 51 and looking forward to retirement in only a few years.

The module will provide the Russian half of ISS a second restroom, greater oxygen and water recycling capacity, and room for a third resident, all necessary additions for the planned two commercial tourist launches Russia has scheduled for the fall.

NASA gives an American the seat on Dragon flight that it had been holding for Russian

10:15 am

NASA yesterday announced that it has added an American astronaut to the next manned mission to ISS, set for October.

NASA said that Kayla Barron will join the Crew-3 mission, launching on a SpaceX Crew Dragon spacecraft scheduled for launch no earlier than Oct. 23. Barron joins NASA astronauts Raja Chari and Tom Marshburn, and European Space Agency astronaut Matthias Maurer, who had been assigned to Crew-3 last December.

The Crew-3 mission will relieve the Crew-2 astronauts who arrived at the station on another Crew Dragon spacecraft April 24. The four Crew-3 astronauts will remain on the station for a six-month stay.

The space agency had been holding that seat open for a Russian, as part of its long term barter arrangement whereby in exchange for flying Americans on Soyuz capsules, Russia flies Russians on American spacecraft. That arrangement had been used repeatedly when the shuttle was flying, but since its retirement the U.S. has been forced to buy its seats on Soyuz as it had nothing to offer in exchange.

With the arrival of SpaceX’s Dragon capsule however NASA has been trying to get the Russians to renew that arrangement. And though an American, Mark Vande Hei, flew for free on a Soyuz last month, the Russians have as yet refused to assign their own astronaut to this upcoming October flight, despite months of negotiations. It appears NASA decided it could wait no longer, and filled the seat with its own astronaut.

In fact, the announcement by Roscosmos on May 13th that the next two Soyuz launches to ISS will carry two commercial passengers each means that Vande Hei cannot return on a Soyuz until next year. The seat he would have used to come home now must be used by these tourists, meaning his mission will now be extended to last for as much as a full year or more.

Unless of course NASA decides to bring him home on a Dragon capsule instead.

Roscosmos announces two commercial tourist flights to ISS

9:49 am

Capitalism in space: Roscosmos, the government corporation that controls of all of Russia’s space industry, announced today that it will be flying two different commercial tourist flights to ISS, both occurring before the end of this year.

The first will take place in October.

Roscosmos [is] sending an actress and a director to the ISS in October with the aim of making the first feature film in space. The film, whose working title is “Challenge,” is being co-produced by the flamboyant head of Roscosmos, Dmitry Rogozin, and state-run network Channel One.

The second will take place in December, and will fly Japanese billionaire Yusaku Maezawa (the man who has already purchased a Moon mission on SpaceX’s Starship) and his assistant Yozo Hirano in a Soyuz capsule to ISS for twelve days.

Let’s review the upcoming tourist flights now scheduled:

Eutelsat invests $550 million in OneWeb

9:22 am

Capitalism in space: The long established European communications satellite company Eutelsat has committed $550 million in investment capital in OneWeb and its internet satellite constellation.

Eutelsat, one of the world’s leading satellite operators, will receive a c.24% equity stake in OneWeb and similar governance rights to the U.K. Government and Bharti Global, making it a significant equity partner and joining leading investors including the U.K. Government, Bharti Global and SoftBank. The investment is expected to be completed in the second half of 2021, subject to regulatory approvals.

This investment raises OneWeb’s total funding to $1.9 billion, and puts it in a good position to complete its 648 satellite constellation on schedule, with the first commercial operations beginning when the total in orbit tops 250 in July, after the next two Soyuz-2 launches.

The commercial history of Russia’s Proton rocket

9:10 am

Doug Messier at Parabolic Arc today published a detailed launch history of Russia’s Proton rocket, outlining its commercial rise beginning in the 1990s and its fall in the 2010s with the arrival of SpaceX.

The fading of Proton reflected strong competition from SpaceX’s reusable Falcon 9 rocket, which captured an increasing percentage of commercial launches with significantly lower prices.

There was also a global shift away from Proton’s bread and butter, the geosynchronous communications satellite, toward large constellations deployed into low and medium Earth orbits.

Proton’s reputation was also damaged by serious quality control problems that affected the entire Russian launch industry. Proton suffered 9 launch failures and one partial failure in the 10 years between 2006 and 2015. The booster was left grounded for as long as a year at a time. Insurance rates for Proton flights soared.

Proton appears to still have six launches on its manifest, but the shift in Russia to its Angara rocket likely means the end of Proton’s long history, begun at the very beginnings of the space age in the 1960s, is in sight.

Soyuz-2 rocket launches 36 more OneWeb satellites

8:53 pm

Capitalism in space: Russia’s Soyuz-2 rocket today successfully launched from its Vostochny spaceport another 36 more OneWeb satellites, raising that internet constellation to 182 satellites of a planned 650 satellites.

The constellation will take 20 Soyuz launches to finish, and like other competitor services such as Starlink, is designed to provide high speed, low latency broadband services to areas where such service is unavailable now. Whereas Starlink is being marketed to individuals, OneWeb’s services are designed for enterprise customers, including broadband providers. User terminals can enable 3G, LTE, 5G, and Wi-Fi service over land, sea, and air.

The leaders in the 2021 launch race:

11 SpaceX
8 China
7 Russia
2 Rocket Lab

The U.S. still leads China 15 to 8 in the national rankings. And these numbers will likely see some change as there are four launches scheduled in the next four days. First ULA’s Delta 4 Heavy will launch a spy satellite tomorrow, then the next day Arianespace will do its first launch this year, launching a commercial Airbus Earth observation satellite with a Vega rocket.

On April 28 SpaceX plans to launch another 60 Starlink satellites, followed on April 29th by the launch by China of the first module of its space station, using their Long March 5B rocket.

Things are heating up, and this is only the beginning.

China and Russia sign agreement to build moon base

10:24 am

The new colonial movement: Yesterday China and Russia announced that they have signed an agreement to jointly work together to build a base on the Moon.

The link above is from the Chinese state-run press, stating:

In a joint statement issued at the conference, the CNSA and Roscosmos said the moon station will be open to all interested countries, international organizations and partners in terms of planning, design, research, development, implementation and operation at all stages and levels of the project.

The Russian state-run press made a similar announcement.

The new Cold War in space is beginning to shape up. On one side will be free enterprise, led by the United States and the many private companies working independently to make their own profits in space, and on the other side will be the former communist nations whose cultures require all such efforts be controlled from the top by the government.

And like the Cold War of the 20th century, the big question will be the actions of third parties, like Europe, India, Japan, the UAE, and other new space-faring nations. Will they join with the U.S., or join China and Russia to gang up on private enterprise? Right now I will not be surprised if all these countries eventually join the Chinese/Russian effort. Worse, I have great doubts about the U.S. government’s commitment to the capitalist path it is presently taking. If enough pressure was applied by these authoritarian regimes we should not be surprised if our generally authoritarian present government decides to join them as well, using their combined power to squelch freedom and private enterprise in space.

The battle is drawn, but the forces for liberty and freedom are sadly outnumbered.

The anti-satellite missile the Soviet Union designed for one of its early space stations

9:25 am

Link here. Apparently a prototype was actually flown in 1975 on the second successful Soviet space station, Salyut 3, a military mission. A more sophisticated version was never flown when the Soviet’s cancelled their military space station program. However, its design was most fascinating:

[L]ittle is known about the specifications and operation of the system, but, according to the Head of Science and Research Center at NPO Mashinostroenia Leonard Smirichevsky, who introduced the weapon, the vehicle’s grenade-like solid propellant charges doubled as engines! RussianSpaceWeb.com’s 3D recreation of the displayed variant established that it held 96 casings with solid propellant arranged in a globular fashion like the petals of a dandelion around a central combustion chamber. Upon their ignition, the chambers/grenades might have fed hot propulsive gas into a single or multiple combustion chambers at the center of the contraption, producing either the main thrust and/or steering the vehicle. When the missile reached the proximity of the target, according to its guiding radar, the entire vehicle would explode and the small solid chambers would eject under their own propulsive force in every direction acting as shrapnel.

The missile had a flight range of about 70 miles, and was designed to destroy any hostile satellite or spacecraft that approached the military station.

Russia hands over last rocket engines to ULA

9:20 am

In a ceremony in Russia yesterday, Roscosmos’s Energomash division completed and handed over ownership to ULA six RD-180 engines, to be used in ULA’s Atlas 5 rocket.

These are the last such engines required as part of the contract. They will also likely be the last Russian engines ULA will ever buy. The company is retiring its Atlas 5 rocket, which requires them, and replacing it with its Vulcan rocket, which will instead use Blue Origin’s BE-4 engine.

Furthermore, as of September 1st, 2021 such commercial space contracts with Russia will be difficult to obtain because of new sanctions imposed on Russia by the Biden administration.

Russia to build own space station; admits Zvezda is failing

9:10 am

Zvezda module of ISS
The Zvezda module, with aft section indicated
where the cracks have been found.

The new colonial movement: On April 12th, the 60th anniversary of the flight of Yuri Gagarin, Russian President Vladimir Putin announced that Russia is going to build its own independent space station, dubbed the Russian Orbital Space Station (ROSS), to replace its half of ISS.

More important however was this carefully worded admission:

In recent years, the ISS has begun to fall apart, with astronauts now frequently discovering cracks. Last week, it was revealed that Russian cosmonauts were still working on plugging a leak first noticed in 2019. The ongoing problems with the international station have prompted Moscow to begin creating a replacement.

What this state-run news article failed to mention is that the cracks and leaks have only been found in Russia’s twenty-year-old Zvezda module, not the rest of ISS. What ISS faces is the failure of the core section of Russia’s half of the station.

This public statement however is the first from Russia that clearly admits that the cracks in Zvezda are likely systemic stress fractures, and the patches to seal them are mere bandaids on a much more fundamental problem that is certain to get worse over time.

The decision to build its own new station is however not really surprising. The American goals in space have been shifting from promoting the government’s program to stimulating the American commercial aerospace industry. International cooperation is no longer the primary goal. The American foreign aid to Russia’s space program from the early days of ISS’s construction has long ago dried up, and Russia is also no longer getting any cash from the U.S. to fly American astronauts to ISS. The incentive to remain a partner has vanished.

If successful this will make three national stations in orbit, ISS, China’s, and Russia’s. In addition, we should start seeing the launch of several private commercial stations sometime this decade.

The competition is going to be glorious, with the results fast-paced and exciting. The moribund days of boring international cooperation where everything was squeezed into a single project, the International Space Station, appear over.

Commerce increases sanctions on Russia impacting space commerce and trade

9:47 am

The Commerce Department last month announced that is increasing the level of sanctions against trade with Russia because it had determined that country had violated international law by using chemical weapons against specific dissidents both in and out of Russia.

On March 4, 2018, the Russia Government deployed a Novichok nerve agent in an attack against former Russian military officer Sergei Skripal and his daughter Yulia Skripal in the United Kingdom. In response, the U.S. Government imposed two sets of sanctions against Russia pursuant to the Chemical and Biological Weapons Control and Warfare Elimination Act of 1991 (CBW Act) in August 2018 and August 2019.

On August 20, 2020, the Russian Government again deployed a Novichok nerve agent, this time against Russian opposition figure Aleksey Navalny, warranting a new determination by the Secretary of State and additional sanctions under the CBW Act.

While this ruling will have a negative impact on any space-related U.S./Russian activities, the full ruling specifically included these waivers:

Soyuz-2 launches three astronauts to ISS

9:08 am

Russia today successfully used its Soyuz-2 rocket to launch three astronauts to ISS.

Because this flight is occurring three days before the 60th anniversary of Yuri Gagarin’s first human flight in space, the Russians gave the Soyuz capsule his name to honor him and the event. The spacecraft docked with ISS only two orbits later.

The crew also included an American, Mark Vande Hei, who is flying as part of the new barter agreement with Russia, whereby Americans fly in Soyuz in exchange for Russians flying in American commercial capsule. This was the first time NASA paid nothing for a flight on Soyuz since the shuttle retired a decade ago.

The return to Earth of Vande Hei and his fellow crew member Pyotr Dubrov will be on the next Soyuz capsule to launch in October, MS-19, in order to accommodate a short visit by a Russian movie director and actress.

Roscosmos will launch Soyuz MS-19 no earlier than October 5 with Commander Anton Shkaplerov and two civilian spaceflight participants. Russian film director Klim Shipenko and a Russian actress, who is yet to be named, will film a movie called “The Challenge” and spend approximately a week aboard the ISS before returning to Earth aboard Soyuz MS-18 with Novitsky.

With this commercial manned flight there will be two such flights in the fall, the Dragon Inspiration4 flight that will not dock with ISS and this Russian one. Both will then be followed by the Axiom commercial tourist flight on a Dragon capsule early in ’22. Expect such commercial manned flights to become somewhat routine in the coming years.

UPDATE: China also launched an Earth observation satellite yesterday, using its Long March 4B rocket
The leaders in the 2021 launch race:

Russia’s first private space tourism company shuts down

9:54 am

Capitalism in space? Russia’s first private space tourism company has been forced to close before it even launched its first rocket because of the obstacles placed before by Russia’s government.

Kosmokurs’ operations will cease due to “insurmountable difficulties” in coordinating with local authorities on the cosmodrome project as well as the company’s “inability to obtain needed regulatory documents from the Defense Ministry” for the design of a suborbital tourist rocket, its CEO Pavel Pushkin told RIA Novosti.

However, the government-run Roscosmos, which controls the rest of Russia’s aerospace industry, has graciously announced it will hire Kosmokurs’ fifty employees.

Do you see a pattern? I do. Kosmokurs was cutting into Roscosmos’s territory. That could not be tolerated, and so the government moved to sabotage it. Now that it is dead, the government can absorb it to try to build its rocket and make money using it.

This kind of mob rule by the Russian government is why that country’s space industry is failing to compete with the new commercial industry coming out of the U.S. and elsewhere. It does not tolerate free competition, only top-down control by the government. The result is that while Russia might eventually fly its own space tourism rockets, it will have only one, and it will likely not be as efficient or as competitive. The only cost advantage it will likely have is Russia’s low wages.

More leaks found in Russian Zvezda module on ISS

10:34 am

Earlier this week Russian astronauts located and patched three more leaks in the 20+ year old Russian Zvezda module on ISS.

Prior to this week’s discovery, the recent patching done by Russian astronauts had reduced the air loss by about half. They need to do another seal test of Zvezda to see if these newer patches have reduced it further.

The report at the link from Russia is as usual very vague. No photos of any of the leaks have been released, by either Russia or NASA. No cause either has been described. This lack of information suggests that the leaks represent a more systemic problem, possibly related to stress fractures from age and wear. If so, it also suggests that Zvezda is nearing its pull-date. How this central module will be replaced from the station remains a major mystery.

Above all, this puts some urgency to the launch of newer modules, such as those being built by the private company Axiom.

Russian gov’t okays extension of U.S cooperative space treaty to ’30

9:45 am

The Russian government yesterday officially approved an extension to 2030 of the cooperative space treaty with the United States that was initially signed in 1992.

According to the TASS article at the link, the U.S. government has already approved this extension. The original agreement was for U.S. flights to the Russian space station Mir. It has been renewed four times since to cover the deal to build and use ISS.

This could very well be the last extension of this deal. By 2030 private commercial American stations should be operational, and the age of some of the oldest sections of ISS will likely need replacement. At that point the U.S. will probably decide to retire its half of ISS.

What the Russians will do is uncertain. The government doesn’t have the cash to build its own station. Nor has that government allowed a private commercial space industry to thrive and thus be financially able to build private commercial stations. Russia may separate its part of ISS and attempt to keep it aloft, but some of their modules are the oldest, and have shown signs of that age.

Russia offers to partner in Turkey’s space program

9:16 am

The new colonial movement: Dmitri Rogozin, head of Russia’s Roscosmos, said yesterday that his agency is eager to partner with Turkey in its new effort to develop its own space program.

Explaining that a draft document is being prepared to make these contacts more systematic and comprehensive, Rogozin said that this will be the legal framework of the peaceful space activities cooperation between Ankara and Moscow.

Pointing out that a strong political will and competent management are required for the realization of space programs, Rogozin said, “Provided that the support of experienced partners is also required, a young space power can easily prepare and implement a full-fledged interplanetary mission in a very short time.”

For Turkey such a partnership would make great sense. Russia has done this kind of work many times in the past, for India, China, and the UAE. No reason Turkey can’t gain from Russia’s help. And Russia could use the cash that Turkey will pay for the business.

Air leak continues despite repairs on Zvezda module of ISS

9:48 am

According to a report today in the Russian press, the air in the Zvezda module of ISS continued to leak away slowly during a test, following this week’s repair of two cracks in the module’s hull.

At about 07:00 GMT on Saturday, ISS cosmonaut Sergei Ryzhikov told a specialist at the Mission Control Center, located near Moscow, that the pressure in the intermediate chamber of the Zvezda module was 678 millimetres of mercury. The pressure stood at 730 millimetres of mercury on Friday evening, right after the hatch of the compartment was closed. Thus, the pressure in the chamber decreased by 52 millimetres of mercury over 11.5 hours.

Based on the thorough nature of the two repairs, this leak must be coming from another very tiny leak that has not yet been detected. Though the leak is very slow and thus not an immediate threat to the astronauts on board, it suggests once again that the leaks are coming from stress fractures resulting from Zvezda’s 20-plus years in orbit. If so, the problem is very serious indeed. Zvezda is the central module for ISS. Replacing it will not be simple or easy.

Russia: Air leaks fixed on Zvezda

9:30 am

According to the Russian state-run press, Russian astronauts have completed their repair work on the ISS module Zvezda and are about to seal the module to test their work.

“The crew of the International Space Station has completed the repair and recovery work on the hull of the Zvezda module. In the coming days, Sergei Ryzhikov and Sergei Kud-Sverchkov will close the hatches in the Zvezda module to check the atmospheric level,” the press office said.

Previous reports suggested the astronauts had located a total of two cracks, both now sealed.

The larger question however remains. Are the cracks stress fractures, and if so do they suggest that Zvezda’s 20-year-old hull is beginning to fail? The Russians have been very silent about these questions, though they have admitted the possibility once or twice, almost as an aside.

Nor has NASA been forthcoming. The American space agency has apparently joined the Russians in keeping this problem out of the news, at all costs. Once, the employees at NASA were Americans who demanded openness from Russia and from themselves. No more. Increasingly our government workers are indistinguishable from Soviet apparatchiks, whose main goal was to protect the government from bad press.

If Zvezda’s hull is failing then ISS faces some very serious engineering issues. They can be solved, but not by silence and sticking one’s head in the sand.

NASA forges deal with private company to put American on Russian Soyuz

9:57 am

Capitalism in space: It appears NASA used the private company Axiom as its go-between to obtain a seat for an American astronaut on the next Soyuz launch to ISS in April.

The deal is very complex.

Based on the initial partnership arrangement between the Russians and NASA, astronauts for both countries would fly in equal numbers on each other’s spacecraft in a barter arrangement that involved no exchange of funds. Russia however has been balking at flying its astronauts on Dragon, claiming it does not yet meet their standards for a manned spacecraft. Thus, they have been demanding that NASA pay them to fly an American on Soyuz.

NASA meanwhile doesn’t have the funds, but it still wants to make sure there is always an American on board ISS, and to do that requires a second ferry besides Dragon to provide redundancy. With Boeing’s Starliner delayed, they have been trying to get a seat on Soyuz as part of that barter deal, to no avail.

The solution? Private enterprise! To get that Soyuz seat at no cost it appears NASA made a barter deal with the private space company Axiom. Axiom is apparently paying the Russians for a seat on next month’s Soyuz flight, which will be filled by a NASA astronaut, and gets in return from NASA a free spare seat on a later American capsule.

The result? NASA pays nothing to the Russians, and still gets its seat on Soyuz. Where Axiom is getting the financing for its purchase is unclear, but because it is getting an extra seat at no cost that it can sell later for a big profit, I suspect that financing was not difficult to obtain.

The details for Axiom’s deal with Roscosmos have not as yet been revealed, though I am sure the Russians charged Axiom plenty for the seat on Soyuz. I also suspect that amount was far less then what the Russians would have charged NASA directly.

Once Starliner finally becomes operational NASA will have enough redundancy for getting Americans to ISS it will no longer need the Russians. Hopefully that will happen by the end of this year. If so, such shenanigans will no longer be required.

China and Russia sign partnership agreement for lunar exploration

2:11 pm

The new colonial movement: China and Russia today signed an agreement outlining a partnership to jointly build a base and orbiting station on and around the Moon.

The International Lunar Research Station (ILRS) is described as a comprehensive scientific experiment base built on the lunar surface or on the lunar orbit that can carry out multi-disciplinary and multi-objective scientific research activities including exploration and utilization, lunar-based observation, basic scientific experiment and technical verification, and long-term autonomous operation. Statements from Roscosmos and CNSA underline that the project will be “open to all interested countries and international partners.”

Though not explicitly stated it is understood that the ILRS would be constructed at the lunar south pole.

Russia is slowly breaking off its partnership with the U.S. because the U.S. is insisting it sign the Artemis Accords, which require all signatories to honor property rights in space. Neither Russian nor China wish to do that, instead reserving those rights wholly to their own governments, their citizens be damned.

Thus, we have a deal for Russia and China to work together. China actually doesn’t need Russia, as it has clearly shown in the past five years that its space capabilities are quite sufficient and well funded. Russia however needs China, as its capabilities have been declining in recent years due to corruption within its aerospace industry as well as a shortage of funds caused by a poor economy and the drop in oil prices.

Working together however could help speed what they achieve while simultaneously fueling the growing international competition in space. In the end this will benefit everyone, as more will get done faster.

How we shall settle the disagreement over property rights and government power in space is a entirely different question, one that I address at great length in my next soon-to-be published book, entitled Conscious Choice: The origins of slavery in America and why it matters today and into the future. Stay tuned!

Russian astronauts begin work to seal 2nd Zvezda leak on ISS

9:27 am

After successfully sealing the largest crack on the twenty-year-old Zvezda module on ISS, Russian astronauts have now begun work on sealing a second such crack.

The report, from Russia’s state-run news service TASS, is not very informative. It does not report the size of the leaks, their nature, and any other important conclusions the Russians have gathered about Zvezda’s overall condition and future, based on these cracks.

Nor has state-run NASA been very transparent on this subject, releasing little further information. The silence from these government entities about the cracks is very worrisome, as it suggests these fixes are merely bandaids on a more serious issue with Zvezda’s structure, and our dishonest and bureaucratic governments do not wish to reveal this fact to the public.

I hope I am wrong, but suspect I am not. If Russia follows its pattern for the past half century, they will provide a more detailed report only after the problem has been completely solved. If these patches are merely temporary fixes over a more serious problem, don’t expect that detailed report for some time.

Update on ISS leaks: Several to be drilled & sealed over next 5 days

8:44 am

According to Russia’s state news service, astronauts on ISS have located several leaks in the 20-year-old Zvezda module of ISS, and will spend the next five days fixing them.

This report clarifies a previous report that left more questions than it answered. It appears that there are several leaks that were found using a microscope sent to the station and temporarily sealed. Now the goal in the next five days will be to permanently seal them.

[A] hole will be drilled at one of the fracture’s ends, which will be filled with cold welding and sealed with a fluoroplastic film on top. The same procedure will be done with other holes. After that, the surface will be sanded and wiped with alcohol wipes and covered with a sealant. Overall, the cosmonauts will put three layers of the sealant.

The repair method suggests that they are all cracks. To stop a crack from growing you drill out the end.

That they are all cracks further suggests that these are all stress fractures. Thus, no matter how permanent these particular repairs are, they cannot solve the greater problem of the aging module itself. We should expect more cracks to appear in the future unless something more drastic is done.

India & Russia successfully launch satellites

11:04 pm

Both India and Russia today successfully launched satellites into orbit.

For India it was their first launch in 2021. Their PSLV rocket put into orbit a Brazillian satellite for studying Earth resources. The launch also included 18 other cubesats.

Russia in turn used its Soyuz-2 rocket to launch a new generation weather satellite for studying that country’s remote Arctic regions.

SpaceX had also planned another Starlink launch but aborted the countdown with just over a minute to go. They plan to try again tomorrow.

The 2021 launch race:

5 SpaceX
4 China
3 Russia
1 Rocket Lab
1 Virgin Orbit
1 Northrop Grumman
1 India

The U.S. still leads China 8 to 4 in the national rankings.

First air leak crack on ISS has not grown

9:25 am

A inspection of the first air leak crack that had been found and patched in the Zvezda module on ISS last year has found that it apparently not increased in size since then.

The size of a crack in the intermediate chamber of the Russian Zvezda module aboard the International Space Station (ISS) remains unchanged, cosmonaut Sergei Ryzhikov reported to Russia’s Flight Control Center on Wednesday. “It [the length] has not changed. As in the previous measurements, I do not see any changes,” Ryzhikov said during his talks with Mission Control broadcast on NASA’s website.

On February 23, the cosmonaut carried out work with a microscope to trace another possible air leak. The photos of the work were transmitted to Earth and the video from GoPro cameras will be sent via the Russian broadband communications system. After completing the work, the cosmonaut reinstalled the patch in the area of the crack.

This Russian report is decidedly unclear about some details. Though it appears the astronaut was using the microscope to inspect another leak, he also apparently removed the patch on the first leak to check the crack for any changes, then replaced it. How one removes and replaces such a patch is a puzzle however. Such things are generally not removable.

No matter. The important detail is that the crack has not grown. If it was a stress fracture the recent dockings of spacecraft to the nearby port might cause it to grow. That it has not is good news.

The bad news is that the inspection did not find the second small leak that is thought to be in this same Zvezda module.

Roscosmos head: Russia to launch 29 rockets in ’21

5:10 pm

Dmitry Rogozin, the head of Russia’s space agency Roscosmos, announced yesterday that they expect to complete 29 launches in 2021.

These numbers include all Russia’s launches, including the ones done for Arianespace in French Guiana. In my regular launch updates I don’t count those as Russian launches, as they are run and controlled by Arianespace, under Arianespace contracts.

Nonetheless, there should be an increase in the number of Russian launches in ’21, as they should resume OneWeb launches that were halted last year due to that company going into bankruptcy and then recovering. That bankruptcy meant that Russia’s total launches last year were less than half what they predicted.

The increase in ’21 does not mean Russia will successfully complete 29 launches. Rogozin and Roscosmos have for years routinely overstated their goals, and I think they are doing so again. I expect Russia to complete around 20-25 launches by the end of the year. If they top 25 it would make ’21 their best year since ’15.
