South Korea successfully launches its Nuri rocket
The new colonial movement: South Korea today successfully launched its home-built Nuri rocket, placing a test satellite, a dummy satellite, and four university cubesats into orbit.
The government program to build this rocket began in 2010 and cost $616 million, though not all of that money was devoted to the rocket. South Korea’s space agency has four more launches planned through 2027.
This was obviously South Korea’s first launch this year. The leaders in the 2022 launch race thus remain the same:
26 SpaceX
18 China
8 Russia
3 Rocket Lab
3 ULA
American private enterprise now leads China 35 to 18 in the national rankings, and leads the entire world combined 35 to 30.

South Korea reschedules launch to June 21 after fixing sensor issue
The new colonial movement: South Korea space officials from its KARI space agency have now rescheduled the second test launch of their home-built Nuri rocket for June 21st, after replacing a fuel sensor on the rocket that was not working.
ARI said engineers identified the problematic part within the sensor and replaced it, and Kwon said they also found no other problems after inspecting the rest of the rocket. Kwon noted that the rescheduled launch date could be subject to change depending on weather conditions.
This will the second time KARI has attempted an orbital launch of Nuri, with the first experiencing an upper stage failure in October 2021.

South Korea postpones tomorrow’s second test launch of its Nuri rocket
The new colonial movement: Because of unexpected sensor reading in the oxygen tank as the rocket was lifted upright at the launch pad, South Korea has postponed its planned launch tomorrow of its home-built Nuri rocket.
According to KARI [South Korea’s space agency], readings of the oxidizer tank sensor normally change when the rocket is being erected. Readings on Nuri’s sensor, however, did not show any change during the process. “The sensor itself could be problematic, or it could be an issue with the cable or the terminal box,” the official said.
This launch would have been the second attempt to complete an orbital launch, with the first Nuri launch failing in October 2021 when tanks inside the third stage broke free during launch.

South Korea cancels probe to asteroid Apophis
The South Korea government has canceled its proposed unmanned probe to asteroid Apophis that had been designed to reach the asteroid during its ’29 close approach of Earth and fly in formation with it.
The science ministry, which manages state-funded space programs, recently ruled the mission “unfeasible” and decided not to request the $307.7 million budget it initially sought for the mission. … “We’ve decided not to pursue Apophis probe mission because there were various issues making it difficult for the mission to be successful,” Shin Won-sik, a science ministry official, told SpaceNews. “To probe Apophis, we have to launch a spacecraft by 2027 at the latest. But with the rocket and spacecraft-making capabilities we have, it’s unrealistic to launch in time.”
South Korean officials insisted they are not abandoning all future asteroid missions, but merely shifting this effort to other asteroids in which there is less time pressure to launch. Right now they are considering a mission in the mid-2030s, which could also be an asteroid sample return mission.

South Korea’s new president wants bigger space effort closely tied to U.S.
The new president of South Korea, Yoon Suk-yeol, has made it clear that when he takes office today his policy will be to expand that nation’s space effort while tying that effort more closely with NASA and the U.S. military.
[His goals] include establishing an independent aerospace agency offering integrated management of civil and military space programs in Sacheon, South Gyeongsang Province, home to nearly 100 aerospace companies, and developing a high-power rocket for independent satellite launches in the near term and lunar and Mars exploration in the long-run.
…Yoon has also promised to facilitate the public-to-private transfer of space technologies, reform regulations and launch a space industry cluster to grow the country’s nascent domestic space industry. In line with this, the science ministry recently selected five universities that will be subsidized $4 million each over the next five years in return for running education programs designed to nurture skilled space engineers.
“Countries jockey for position in the space industry to secure a competitive edge in national security and future competitiveness,” Yoon wrote in his election manifesto, pledging to make South Korea “one of seven most advanced space powers in the world by 2035.”
However, the first space-related task of Yoon’s adminstration, which merely accelerates what the previous South Korean government had been doing, will likely be to replace the Russian rockets that South Korea presently has contracts with to launch several satellites.

South Korean smallsat rocket startup to launch first suborbital test flight
Capitalism in space: A new South Korean smallsat rocket startup company, Innospace, is now planning its first suborbital test launch in December, launching a Brazilian military payload from that country’s Alcântara Space Center.
The 16.3-meter, single-stage test rocket is a precursor to the company’s planned commercial satellite launcher Hanbit-Nano, a two-stage small satellite launcher designed to carry up to a 50-kilogram payload to a 500-kilometer sun-synchronous orbit. The first stages of the two rockets are powered by a 15-ton-thrust hybrid rocket engine that uses liquid oxygen and paraffin-based propellants. Hanbit-Nano’s upper stage is equipped with a 3-ton hybrid engine, according to the Sejong-based company’s website.
“If the upcoming test launch is successful, we will start preparing for a test launch of Hanbit-Nano,” Innospace spokesperson Kim Jung-hee told SpaceNews.
The company has so far raised almost $28 million in private investment capital. It also has an agreement with Norway to launch its rockets from there.
Since South Korea’s government has its own rocket program, it will be interesting to see which succeeds first in getting into orbit.

South Korea raises its space budget by 19%
The new colonial movement: The South Korean government has decided to further raise its space budget for ’22, increasing the planned budget from what was spent in ’21 by 19%.
About a third of this $619 million budget will be used to develop the country’s home-built rocket. Slightly more than half will finance several different satellite projects. Much of the rest is budgeted for the nation’s planned unmanned probes to the Moon and to the asteroid Apophis.

South Korea to build its own unmanned lunar lander
The new colonial movement: The government of South Korea has begun a project to build its own unmanned lunar lander, scheduled for launch sometime in the 2030s.
South Korea presented an action plan to develop a lunar lander weighing more than 1.5 tons that would carry out scientific research on the surface of the moon in the 2030s. The project is to begin in 2024 after a preliminary feasibility study.
The Ministry of Science and ICT would form a working group of industry-academic experts to conduct research on a lunar lander and draw up strategies and detailed plans by August 2022. It is a follow-up project to launch a lunar orbiter in August 2022. The lunar lander will be lifted by a next-generation homemade rocket.
The goal is to encourage the country’s own aerospace industry. The working group will spend the next month recruiting South Korean companies to join the project.
South Korea however has to first get its own homemade rocket, Nuri, to successfully launch. The first launch attempt in October 2021 failed, and the second has been delayed to fix the cause.

UK bans all space-related exports to Russia
In response to Russia’s invasion of the Ukraine, the United Kingdom yesterday announced new sanctions, banning all space-related exports as well as increased sanctions on aviation.
For Russia, this component of these new space sanctions might be the most painful, should something go wrong on one of its launches:
The space export ban includes all related services, including insurance or reinsurance services, U.K. officials said. “This means cover is withdrawn on existing policies and UK insurers and reinsurers will be unable to pay claims in respect of existing policies in these sectors,” wrote in the statement.
This restriction also means that any satellite customers will not be able to claim damages. Thus, customers like South Korea, which still has two launches planned on Russia rockets, will lose everything if the launch fails. Because of this, it is almost certain that it will cancel these launches,

Launch of two South Korean satellites threatened by Russia’s Ukraine war
According to South Korean officials, the launch later this year of two new home-built satellites on Russian rockets is now unlikely because of the sanctions imposed because of Russia’s invasion of the Ukraine.
South Korea’s CAS500-2 remote sensing satellite is set to launch in the first half of this year on a Russian Soyuz rocket from Russia’s Baikonur Cosmodrome in Kazakhstan. South Korea’s KOMPSAT-6 multipurpose satellite, equipped with synthetic aperture radar (SAR), is due to launch in the second half of the year on a Russian Angara rocket from Plesetsk Cosmodrome in northern Russia.
“For now, nothing has changed to the plan,” Korea Aerospace Research Institute spokesman Roh Hyung-il told SpaceNews. “We are taking a close look at how the situation unfolds because it could have a significant impact on our missions.” He admitted that it’s “very likely” that the satellites won’t be launched as planned.
Those officials also said that losing Russia as a launch option will be a “serious blow” to South Korea’s entire space effort. I find that puzzling. There are plenty of other rocket companies now available. Why South Korea feels a need to depend on Russia seems short-sighted.

South Korea pinpoints cause of October launch failure
The new colonial movement: South Korea’s space agency KARI has completed its investigation of the launch failure in October of its first entirely home-built Nuri rocket, revealing that the support structures for the rocket’s helium tanks were designed incorrectly, and allowed the tanks to break free during launch.
“The support structures holding helium tanks inside the third-stage oxidizer tank were not properly designed to account for a force referred to as buoyancy,” KARI said in a Dec. 29 statement. Buoyancy, the upward force exerted by a fluid that pushes an object, rises along with a rocket’s altitude, which was not accounted for, according to KARI.
The helium tanks with the faulty anchors were inside the upper stage’s oxidizer tank, which was filled with liquid oxygen needed for the rocket’s ignition. With the helium tanks coming loose, they disrupted pipelines within the oxidizer tank and led the liquid oxygen to leak, resulting in early termination of the ignition, KARI explained.
The helium is used to keep the tank pressurized as it uses up its oxygen so that oxygen will continue to flow to the engine. Thus, they sit inside the oxygen tanks, and when they came loose they damaged its internal pipes.
Though they can fix the problem, it will likely cause a delay in the second Nuri launch attempt, presently scheduled for May.

South Korean lawmaker proposes his country build a reusable rocket
The new colonial movement: Following a meeting with high space officials, a South Korean lawmaker announced yesterday that his country is now planning the design and construction of a reusable rocket.
“Starting next year, the development of a high-performance reusable rocket with liquid-fueled 100-ton thrust engines will begin,” said Rep. Cho Seung-rae of the ruling Democratic Party of Korea, who represents the committee. “Having such a liquid-fueled high-performance rocket engine is necessary [for South Korea] to successfully fulfill the missions of launching a [robotic] lunar lander by 2030 and building the Korea Positioning System by 2035 on its own.”
Cho said the envisioned engine will be “capable of controlling its thrust with four consecutive reburns,” a function which he said would “significantly slash launch cost.” The lawmaker said the government will carry out two-year preliminary research on the issue, with the budget of 12 billion won ($10.2 million) in hand.
South Korea has yet to successfully launch its own homebuilt Nuri rocket, with the first test flight failing less than a month ago.
In addition, this announcement was a surprise, as the budget request for ’22, made in September, had not included it. It appears that this lawmaker and those high space officials teamed up to propose it. We shall see if it gets into the final budget.

South Korea’s new Nuri rocket fails during first launch
The new colonial movement: South Korea’s new Nuri rocket, that country’s first homegrown rocket, failed during launch early today when the payload did not reach its proper orbit.
It appears that the third stage shut down prematurely.
They plan to try again in May ’22.
For a first launch attempt this was actually a large success. Getting the first and second stages to work properly is generally the hardest part of any rocket launch.

The boom in commercial space continues
Modern rocketry soaring under freedom
Capitalism in space: In the last two days there have been so many stories about different space companies winning new contracts I think it is important to illustrate this in one essay, rather than in multiple posts. Below is the list:
- SpaceX wins contract to launch Yahsat’s Thuraya 4-NGS satellite
- Rocket Lab wins multi-launch deal for IoT constellation
- Sierra Space and Kanematsu Corporation Creating Japanese Partnerships to Advance International Commercialization of Low-Earth Orbit
- OneWeb and AT&T partner to extend fiberlike coverage across United States
- Isar Aerospace to launch OroraTech wildfire monitoring cubesat constellation
- South Korea to spend $593 million on public-to-private transfer of rocket technologies
Just another contract that illustrates SpaceX’s growing market dominance in the larger satellite and payload business. The company already gets about 90% of the launches for lunar probes. It now appears that for the big comercial satellites, SpaceX’s lower prices are allowing its market share to approach that same number.
This contract is for the launch of 25 satellites, and thus solidifies Rocket Lab’s market share as many other smallsat rocket companies arrive to compete with it.
This press release suggests that Kanematsu will be the another customer for the private space station that Sierra Space is planning to build and launch.
This deal illustrates the growing strength of the satellite industry that feeds the growing launch industry. The OneWeb/ATT partnership is aimed at making the OneWeb satellite constellation available to more customers more quickly.
This German startup has not yet launched anything, but it has raised a lot of capital as it develops its Spectrum rocket for a planned first launch in ’22. This contract is for “multiple launches.”
The last two stories are possibly the most significant, because both show that the shift in space from government-built to privately-built, as I advocated in my 2017 policy paper, Capitalism in Space, is spreading to other countries. » Read more
South Korea to launch its own rocket in October
The new colonial movement: South Korea is now targeting October 21, 2021 for the first test launch of its home-built Nuri rocket.
The October flight will be South Korea’s first domestic orbital launch attempt in more than eight years. On Jan. 30, 2013, a Naro-1 rocket placed the STSAT-2C technology demonstration satellite into low Earth orbit.
It was the final of three launches for now retired Naro-1, which consisted of a Russian Angara first stage with a downgraded engine and a South Korean developed solid-fuel upper stage. Two previous Naro-1 launches failed in 2009 and 2010.
They have also scheduled a follow-up test launch in May ’22, assuming all goes well on this first test launch.

South Korea signs the Artemis Accords
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.

South Korea’s leader announces his nation’s goals in space
The new colonial movement: Moon Jae-in, South Korea’s president since 2017, on March 25th gave his first speech focused on his nation’s goals in space, outlining plans to encourage private enterprise as well as achieving an unmanned mission to the Moon by 2030.
His speech listed three main programs. First, they are developing their own home-built rocket, dubbed the KSLV-2, which they hope to launch on its first orbital test flight by October of this year.
Second, he touted a project to send a probe to the asteroid Apophis in 2029. I described this probe in my November 2020 report on a science conference focused entirely on Apophis. If all goes well, they hope to have the probe fly in formation with the asteroid as it makes its close approach that year.
Third, he committed his nation to landing an unmanned lander on the Moon by the end of this decade. (Sound familiar?)
While much of this was the typical photo-op stuff that politicians love, designed mostly to enhance their public image, Moon did make it clear their goals are also to foster a new private aerospace industry that would compete in the emerging new space market.
Moon underscored the role of the private sector in enhancing Korea’s space development capabilities. To that end, he said, the government will step up efforts to build an “innovative industrial ecosystem that nurtures global space companies such as SpaceX.”
Another issue he put forth was strengthening international competitiveness of made-in-Korea satellite systems, in the lead-up to the introduction of 6G wireless networks, self-driving vehicles, and other products and services enabled or enhanced by satellites.
All-in-all, it is actually surprising that up to now South Korea has not made its presence felt in space. This announcement suggests they now intend to change that.

South Korea test flies its first home-built rocket engine
The new colonial movement: South Korea yesterday successfully completed a suborbital test flight of its first home-built rocket engine.
The 75-ton-thrust engine was fired up and launched the first-stage rocket at the Naro Space Center in Goheung, South Jeolla Province, at 4 p.m., as part of the country’s long-term project to launch the Korea Space Launch Vehicle-2 (KSLV-2), dubbed Nuri, in 2021.
The Ministry of Science and ICT said it achieved an engine burn-time of 151 seconds, which exceeded its goal. It earlier said the test launch would be considered a success if the engine maintained a burn-time of about 140 seconds. The test rocket also reached a maximum altitude of 209 kilometers, 319 seconds after liftoff, and safely landed in international waters southeast of Jeju Island.
The planned orbital launch in 2021 makes this one of many new rockets, from both countries as well as private companies, set to become operational in the early 2020s. It looks like that decade will be especially exciting for space.

The test rocket also reached a maximum altitude of 209 kilometers, 319 seconds after liftoff, and safely landed in international waters southeast of Jeju Island.
The planned orbital launch in 2021 makes this one of many new rockets, from both countries as well as private companies, set to become operational in the early 2020s. It looks like that decade will be especially exciting for space.
Big earthquake in South Korea linked to geothermal power plant
South Korea’s second largest earthquake has now been linked by two different studies to the injection of water deep below the surface at a new geothermal power plant.
Perched on South Korea’s southeast coast and far from grinding tectonic plates, Pohang is an unlikely spot for a big earthquake. Before the geothermal plant’s two wells were drilled, there had never been an earthquake there of any significance, says Kwanghee Kim, a seismologist at Pusan National University in Busan, South Korea, and lead author of one study. But while Kim was monitoring the aftermath of an unrelated earthquake in 2016, he began to detect rumbles from Pohang. That prompted his lab to deploy eight temporary seismic sensors at the site, which were finally in place on 10 November 2017. He expected any quakes to be small—after all, the largest previous quake tied to enhanced geothermal power, in Basel, Switzerland, was just 3.4 in magnitude.
It took only 5 days to be proved wrong. “The Pohang earthquake was larger than any predicted by existing theories,” Kim says. Although some initial measures placed the source of the quake several kilometers away from the plant, Kim’s network revealed that the earthquake, and several of its foreshocks, all began right below the 4-kilometer-deep well used to inject water into the subsurface to create the plant’s heating reservoir. Indeed, it appears likely that the well’s high-pressure water lubricated an unknown fault in the rock, causing it to slip and triggering the quake, Kim says.
A second paper, by European scientists who used regional seismic data, reinforces the South Korean team’s results, in particular its shallow depth. That study also points out that an earlier 3.1-magnitude earthquake also took place near the well bottom, increasing the odds of a common source. Satellite measures of shifts in the surface after the November 2017 quake support that idea, says Stefan Wiemer, the second study’s lead author and director of the Swiss Seismological Service in Zurich. It’s clear the locked fault was storing energy that was waiting to be released, Wiemer says. “If that fault would have gone next Tuesday or 50 years from now, we’ll never know.”
The article notes that scientists had previously concluded that injecting water underground for geothermal purposes was okay (since it reduced use of fossil fuels) while doing the same for fracking (to obtain and use fossil fuels) was bad.. The data here actually suggests just the reverse, since fracking has never produced an earthquake as large as the 5.5 magnitude Pohang quake.

China and South Korea agree to counter North Korea’s missile/nuclear program
Under pressure from the Trump administration to do something about North Korea’s out-of-control and aggressive nuclear and missile program, China has worked out an agreement with South Korea to take “strong action”.
It remains a question how serious this response will be, but it is also the first sign in a long time that China is finally taking the threat from North Korea seriously.
Update: China refuses acceptance of coal from a fleet of North Korean ships.
This new story confirms that China was serious about this ban when it announced it in February. Set to run to at least the end of this year, the loss of income to North Korea, very poor already, should have some influence there. Whether good or bad, however, remains unknown. One cannot expect irrational and mad individuals holding great power to come to rational conclusions.

Angara gets a customer
The competition heats up: Russia has signed its first international contract for its new still-underdevelopment Angara rocket.
Leading Russian rocket developer, GKNPTs Khrunichev, signed up the first foreign commercial passenger for the light version of its new-generation Angara rocket. The South-Korean Kompsat-6 remote-sensing satellite (a.k.a. Arirang) was booked for a ride on the Angara-1.2 launch vehicle from Plesetsk around 2020. Equipped with a Synthetic Aperture Radar, SAR, the 1.7 ton spacecraft should be inserted into the Sun-synchronous orbit.

The sad state of South Korea’s space sector
The new colonial movement: It appears that South Korea’s space industry is faltering, according to unnamed sources in that industry, and must be revitalized.
Many critics also point to the near absence of Korean conglomerates in the domestic aerospace scene as a major setback for the nation. “Since space businesses do not generate short-term revenues, most Korean conglomerates are reluctant to jump into the sector,” said an official from the aerospace sector. “Other nations, including the U.S. and Russia, on the other hand, have been running space programs for decades and have a large pool of seasoned engineers and talents, which is why the Korean aerospace industry is far behind in the race for outer space,” he said.
Samsung Group, the largest conglomerate here, previously ran aerospace business arm Samsung Techwin, now renamed Hanhwa Techwin after it was acquired by Hanhwa Group in 2014. Techwin was established in 1977 to develop flight engines. Samsung Group sold part of Techwin’s flight engines business to Korea Aerospace Industries in 1999 and pulled completely out of the aerospace sector in 2014.
What makes this story different from my previous two posts is that its focus is not building a government program (and the bureaucracy to go with it) but to find way to develop a robust private aerospace industry, competing for market share in the world market. With that approach, South Korea might actually launch something in the coming years.

South Korea commits almost a billion dollars to AI research
In reaction to the recent Go victory by a computer program over a human, the government of South Korea has quickly accelerated its plans to back research into the field of artificial intelligence with a commitment of $863 million and the establishment of public/private institute.
Scrambling to respond to the success of Google DeepMind’s world-beating Go program AlphaGo, South Korea announced on 17 March that it would invest $863 million (1 trillion won) in artificial-intelligence (AI) research over the next five years. It is not immediately clear whether the cash represents new funding, or had been previously allocated to AI efforts. But it does include the founding of a high-profile, public–private research centre with participation from several Korean conglomerates, including Samsung, LG Electronics and Hyundai Motor, as well as the technology firm Naver, based near Seoul.
The timing of the announcement indicates the impact in South Korea of AlphaGo, which two days earlier wrapped up a 4–1 victory over grandmaster Lee Sedol in an exhibition match in Seoul. The feat was hailed as a milestone for AI research. But it also shocked the Korean public, stoking widespread concern over the capabilities of AI, as well as a spate of newspaper headlines worrying that South Korea was falling behind in a crucial growth industry.
South Korean President Park Geun-hye has also announced the formation of a council that will provide recommendations to overhaul the nation’s research and development process to enhance productivity. In her 17 March speech, she emphasized that “artificial intelligence can be a blessing for human society” and called it “the fourth industrial revolution”. She added, “Above all, Korean society is ironically lucky, that thanks to the ‘AlphaGo shock’, we have learned the importance of AI before it is too late.”
Not surprisingly, some academics are complaining that the money is going to industry rather than the universities. For myself, I wonder if this crony capitalistic approach will produce any real development, or whether it will instead end up to be a pork-laden jobs program for South Korean politicians.

Using Roman tactics to quell riots
An evening pause: The following was a drill by South Korean police to practice the techniques they use to control demonstrations and riots. Anyone who knows anything about Roman military tactics will instantly recognize what they are doing.
While this is not a real world situation, in an actual riot these techniques are certainly going to be effective. They also illustrate who is the civilized side in these disturbances.

South Korea unveils its own lunar rover
The competition heats up: South Korea has revealed its preliminary design for a lunar rover, set to launch in 2020 on a Korean-built rocket.
The article does not indicate whether this project has actually been approved or is merely being touted by Korea Institute of Science and Technology, which made the announcement. The cost to build it is estimated to be more than $7 billion, which seems quite exorbitant and over-priced.
Update: I had misread the conversion in the article from U.S. to Korean currency and thought the proposed cost for this mission was way more than it really is, which is about $7 million, a much more reasonable number. Thanks to Edward for the correction.

North Korea on Wednesday closed access to the Kaesong Industrial Park, a joint factory zone with South Korea.
Bad news: North Korea on Wednesday closed access to the Kaesong Industrial Park, a joint factory zone with South Korea.
Experts on the Korean situation had noted that we shouldn’t take seriously the harsh language coming out of North Korea as long as Kaesong was in operation. Thus, this news is very bad indeed.
