South Korea’s Danuri orbiter enters lunar orbit

2:35 pm

South Korea’s first lunar orbiter, dubbed Danuri, has successfully entered lunar orbit after a four-month journey designed to save fuel and weight.

The Danuri spacecraft was expected to begin entering lunar orbit at on Friday (Dec. 17) at 2:45 p.m. EST (1945 GMT, 2:45 a.m. Dec. 17 in South Korea), according to a statement (opens in new tab) from the Korea Aerospace Research Institute (KARI). The maneuver, the first of five planned engine burns through Dec. 28 to refine Danuri’s orbit around the moon, will clear the way for the probe to get started on its lunar science objectives.

Danuri, also known as the Korea Pathfinder Lunar Orbiter (KPLO), began its long and circuitous journey to the moon on Aug. 4, launching on a SpaceX Falcon 9 rocket from Florida’s Cape Canaveral Space Force Station. The moon probe has traveled over 3.3 million miles (5.4 million kilometers) on its journey so far, KARI officials have said.

Its six instruments, including one American camera designed to look into the permanently shadowed craters on the Moon, will study the Moon from a polar orbit.

More results from DART impact of Dimorphos

9:44 am

Didymos and Dimorphos as seen from Earth
Click for movie.

At a science conference this week scientists provided an update on the changes that occurred to the asteroid Dimorphos after it was impacted by the DART spacecraft in September, shortening its orbit around the larger asteroid Didymos by 33 minutes.

The image to the right is a screen capture from a short movie made from 30 images taken by the Magdalena Ridge Observatory in New Mexico, and part of a new image release of the asteroid pair.

It shows the motion of the Didymos system across the sky over the course of roughly 80 minutes, and features a long, linear tail stretching to the right from the asteroid system to the edge of the frame. The animation is roughly 32,000 kilometers across the field of view at the distance of Didymos.

According to the scientists, the impact displaced more than two million pounds of material from Dimorphos.

Observations before and after impact, reveal that Dimorphos and its larger parent asteroid, Didymos, have similar makeup and are composed of the same material – material that has been linked to ordinary chondrites, similar to the most common type of meteorite to impact the Earth. These measurements also took advantage of the ejecta from Dimorphos, which dominated the reflected light from the system in the days after impact. Even now, telescope images of the Didymos system show how solar radiation pressure has stretched the ejecta stream into a comet-like tail tens of thousands of miles in length.

Putting those pieces together, and assuming that Didymos and Dimorphos have the same densities, the team calculates that the momentum transferred when DART hit Dimorphos was roughly 3.6 times greater than if the asteroid had simply absorbed the spacecraft and produced no ejecta at all – indicating the ejecta contributed to moving the asteroid more than the spacecraft did.

This information is teaching us a great deal about these two particular asteroids, which could be used if for some reason their totally safe orbit got changed and they were going to impact Earth. However, NASA’s repeated effort to make believe this info would be useful for deflecting other asteroids is somewhat absurd. It is helpful, but each asteroid is unique. The data from DART is mostly helping astronomers get a better understanding of the geology of these specific asteroids, which will widen their understanding of asteroids in general. Planetary defense is really a very minor aspect of this work.

Russian official: Soyuz leak possibly caused by micrometeorite hit

9:17 am

According to Sergei Krikalev, who heads Roscosmos’ manned program, the leak of coolant from the Soyuz capsule docked at ISS could have been caused by a micrometeorite hit.

Sergei Krikalev, a veteran cosmonaut who serves as the director of crewed space flight programs at Roscosmos, said a meteorite striking one of external radiators of the Soyuz MS-22 capsule could have caused the coolant to escape.

The malfunction could affect the performance of the capsule’s coolant system and the temperature in the equipment section of the capsule but doesn’t endanger the crew, Krikalev said in a statement.

Krikalev said Russian flight controllers were assessing the situation and following temperature indicators on the Soyuz. “There have been no other changes in parameters on the Soyuz spacecraft and the station, so there is no threat for the crew,” he said.

The “equipment section of the capsule” is its service module, not its habitable orbital module or descent module.

Krikalev, the first Russian to fly on the space shuttle and occupy ISS, is a generally very reliable source. He is speculating, but not wildly but based on what is so far known. The upcoming inspection of the Soyuz using an ISS robot arm will soon tell us whether he is right or not. Krikalev also said that the inspection will tell them whether this capsule can be used to return its astronauts to Earth.

China launches test satellite

9:04 am

The launch list changes immediately! China also completed a successful launched today, using its Long March 11 rocket to put an experimental satellite into orbit, designed to do “in-orbit verification of new space technologies.”

The rocket is solid-fueled, and designed to launch quickly as needed. No word on where its lower stages crashed inside China.

The updated leaders in the 2022 launch race:

60 China
57 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 81 to 60 in the national rankings, but trails the entire world combined 92 to 81.

SpaceX launches oceanography satellite

8:57 am

SpaceX early this morning used its Falcon 9 rocket to successfully launch an oceanography satellite, dubbed SWOT, for both NASA and France’s space agency CNES.

The satellite it designed to measure the height of water on 90% of the Earth’s surface.

The first stage was making its sixth flight, and successfully returned to Earth, touching down on its landing pad at Vandenberg Space Force Base.

The leaders in the 2022 launch race:

59 China
57 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. now leads China 81 to 59 in the national rankings, but trails the entire world combined 91 to 81.

These numbers however should change again later today, as SpaceX has another launch scheduled.

Today’s blacklisted American: Conservative students and pro-speech law firm slandered and threatened at University of Kansas

11:30 am

The University of Kansas Law School: Eager to blacklist

Today’s blacklisted American: When a chapter of the Federalist Society at the University of Kansas Law School scheduled an event featuring a speaker from the Alliance Defending Freedom (ADF), a pro-speech legal firm that has won many cases at the Supreme Court, the school’s “Diversity, Equity, Inclusion, and Belonging Committee” falsely claimed ADF promoted “hate speech”, and two members of the school’s faculty then tried to get the chapter to cancel the event.

The story of what happened are outlined in detail by a justice of the Kansas Supreme Court, Caleb Stegall, in his resignation letter [pdf] in protest of the college’s unwillingness to defend the principle of free speech and open debate. As he wrote, first the law school administrator called a meeting with chapter’s board of students:

France orders Eutelsat to stop broadcasting Russian channels

9:13 am

Arcom, the French television regulation agency, yesterday ordered the communication satellite company Eutelsat to stop allowing three Russian channels from broadcasting using the satellites.

In a news release, Arcom said the television stations’ coverage of Russia’s war in Ukraine “include repeated incitement to hatred and violence and numerous shortcomings to the honesty of the information.” Eutelsat said in a brief statement that “it will no longer be involved in the broadcasting of the three sanctioned channels within the prescribed time-frame.”

Arcom’s decision comes a week after France’s top administrative court, prompted by a request from the Paris-based Reporters Without Borders advocacy group, ordered Arcom to review an initial decision to permit Eutelsat to continue carrying the stations.

Arcom’s claim, that it made this order because of the content of the broadcasts, is another example of the blacklisting/censorship culture we now live in. The French regulators could have simply stated that, as an ally of the Ukraine in the Russian-Ukraine war, it does not want French-regulated satellites to provide aid to the Russian side. There is a war going on, and this alone is a rational reason to block the Russian channels.

Instead, Arcom uses censorship as its justification. It doesn’t like what the Russians are saying, and therefore has the right to censor them. Remember this argument, because in the future Arcom will likely use it again, but next time against any one of the other broadcast channels under its control that simply says something it doesn’t like.

China launches classified remote sensing satellite

8:57 am

Using its Long March 2D rocket, China last night successfully launched a classified remote sensing satellite into orbit.

The launch was from an interior spaceport. No word on where the first stage crash-landed.

The leaders in the 2022 launch race:

59 China
56 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 80 to 59 in the national rankings, but now trails the entire world combined 90 to 81.

Though SpaceX led China in successful launches for most of the year, China historically tends to do a lot of launches in the November-December time period. This is why it has surged ahead in the past month. SpaceX can still catch up, however, as it still has five launches planned for 2022. Either way, we will not know who comes out ahead until probably the end of the year.

That a private American company however has even a chance of beating out the entire world in annual launches is quite remarkable, whether or not SpaceX ends up ahead.

The first launch of China’s Zhuque-2 rocket ends in failure

1:31 pm

The first launch of China’s Zhuque-2 rocket, built by the pseudo-private company Landspace, ended in failure today when the upper stage had problems after separation of the first stage.

Apparent spectator footage posted on Chinese social media showed the rocket ascending into clear skies, trailed by white exhaust. While the first stage is understood to have performed well, separate apparent leaked footage suggests that issues affecting the rocket’s second stage resulted in the failure of the mission.

Data suggest an expected burn of the stage’s vernier thrusters, intended to carry the stage and payloads into orbit after a burn by the main engine, did not occur as planned.

If this launch had been successful, it would have made the Zhuque-2 rocket the first rocket to reach orbit using methane as a fuel, beating three different American companies, SpaceX, Blue Origin, and Relativity.

Relativity has been preparing for the first launch of its Terran-1 rocket since October, with a goal of launching before the end of the year. At the moment however no launch date is set, though the company’s CEO seems confident it will launch soon.

In addition, SpaceX has also been targeting the first orbital launch of its Starship/Superheavy rocket by the end of this year. As with Relativity, no launch date has been set.

The first launch of Blue Origin’s New Glenn rocket meanwhile is nowhere in sight, as yet. It was originally supposed to launch in 2020, but even now has four launches scheduled on its manifest for 2023. None however have been scheduled, and the first launch will likely slip to late in the year, if that soon.

Today’s blacklisted American: Book touting Judeo-Christian values blacklisted from libraries

1:03 pm

Kirk Cameron, blacklisted

They’re coming for you next: Librarians across America — the same ones running drag queen storybook hours with little kids — are routinely blacklisting television actor Kirk Cameron from doing his own library event reading his own book, As You Grow, because it tries to teach children traditional Judeo-Christian values.

It is common for community libraries to run story-hour programs for kids and parents that correspond with the release of a new book. In recent years, libraries have come under fire for promoting drag queens and other LGBTQ+ centric story hours for young children. It now appears to be the case that those same libraries, which are largely funded by taxpayers, have decided there is no space in their programming lineups for more traditional and faith-based titles.

Cameron’s book, As You Grow, ‘teaches biblical wisdom and the value of producing the fruit of the spirit: love, joy, peace, patience, kindness, goodness, gentleness, faithfulness, self-control,’ according to the author.

You can buy Cameron’s book here.

Space Force and South Korea set up joint office to monitor North Korea

9:37 am

The U.S. Space Force has now partnered with a new South Korean Air Force space division to jointly monitor the space-based and military actions of North Korea, including its increasingly aggressive missile testing program.

From the first link:

[Brig. Gen. Anthony Mastalir, commander of the U.S. Space Forces Indo-Pacific.] later told reporters the unit will undergo analysis in the coming months to assess its mission capabilities and said it is interested in holding discussions with South Korea regarding specific future missions, like missile warning and defense.

The new unit is expected to help monitor, detect and trace projectiles from the North and elsewhere in an operation likely to reinforce overall deterrence capabilities of the South Korea-U.S. alliance, observers said.

This new office really isn’t anything new, simply the renaming and reshuffling of the military bureaucracy from the American Air Force to the Space Force. The military has been present in South Korea since the Korean War in the early 1950s, monitoring North Korea. All that has really changed is North Korea’s growing ability to launch missiles, thus changing the focus of that monitoring, combined with South Korea’s recent effort to accelerate its own space effort, both civilian and military.

NASA, Boeing, and the UAE negotiating partnership for building Lunar Gateway airlock

9:26 am

According to press reports in the United Arab Emirates (UAE), that country is negotiating with NASA and Boeing on a partnership to build an airlock module for NASA’s Lunar Gateway Moon space station.

US aerospace company Boeing said it has held discussions with Emirates officials about the UAE providing an airlock module on the Lunar Gateway. This is an airtight room that astronauts would use to enter and exit the space station.

John Mulholland, vice president and International Space Station programme manager at Boeing, told The National that the company was “actively working” with the UAE on the concept and design.

It appears the UAE is offering to pay Boeing to build it for NASA, and would expect in exchange a larger share in the use of the station.

If this deal works out, the UAE will essentially replace Russia as a Gateway partner. Russia had signed an agreement with NASA in 2017 to build that airlock, but that deal is now null and void following the Russian invasion of the Ukraine and its desire to partner with China instead.

For the U.S., this is a win-win, since it will now be an American company building the airlock, not Russia.

Rwanda and Nigeria to sign Artemis Accords

9:13 am

Rwanda and Nigeria have become the first two African nations to sign te Artemis Accords, bringing the number of signatories to this American-led alliance to 23.

Neither Nigerian nor Rwandan officials described in detail any plans to participate in Artemis at the signing ceremony, but at the Secure World Foundation event, a State Department official said that is not a condition for signing the Accords.

“We continue to encourage all responsible spacefaring nations to sign the Accords, and we also encourage countries that are just developing their space sector to also consider signing,” said Kristina Leszczak of the State Department’s Office of Space Affairs. “We stress that interested countries do not need to come to the table with existing space capabilities or even near-term plans to contribute to Artemis. We find this opens the conversation up to a much more diverse group.”

The full list of signatories so far: Australia, Bahrain, Brazil, Canada, Columbia, France, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, South Korea, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

The accords, bi-lateral agreements between each nation and the U.S., were designed during the Trump administration to emphasize the rights of private investors in space and thus do an end-around of the Outer Space Treaty. Under the Biden administration it is no longer clear if that remains the goal. The existence of a signed alliance led by the U.S. and the capitalistic west however gives the U.S. the political force to protect those rights, assuming the American government is interested in the future in doing so.

Ariane 5 successfully launches three satellites

3:33 pm

Arianespace’s Ariane 5 rocket successfully launched two communications satellites plus a weather satellite today, leaving that rocket only two more launches left before it is permanently retired.

As this was only the fifth successful launch this year by Arianespace (representing Europe), the leader board in the 2022 launch race remains unchanged:

58 China
56 SpaceX
21 Russia
9 Rocket Lab
8 ULA

The U.S. still leads China 80 to 58 in the national rankings, but now trails the entire world combined 90 to 80.

Today’s blacklisted Americans: Archaeologists go underground to practice their research

11:44 am

What modern academia demands from teachers, researchers, and students
Mindless conforming robots: What today’s leftist academia demands

The modern dark age: In order to do their archaeological research free from the Marxist and bigotry tropes now required in academia — or else be blacklisted — many young archaeologists are now going underground, forming anonymous chat groups to discuss their work safe from blacklisting.

The essay at the link first outlines in detail the oppressive leftist culture that now makes honest and open scientific research difficult if not impossible among our intellectual class. Dare to say or write anything that even suggests some cultures are different or better than others and you will be ostracized so quickly you won’t know what happened to you.

Research: Those who get the jab are intolerant and eager to discriminate

9:21 am

According to a new peer-reviewed research paper in Nature that studied more than 15,000 people in 21 countries, those who chose to get COVID shots are strongly intolerant of those who have not, and express that intolerance with an eagerness to deny others their human rights.

The research found that vaccinated people express discriminatory attitudes towards individuals who are unvaccinated at levels as high as or higher than discriminatory attitudes directed towards other common targets of prejudice, such as immigrant populations or people who struggle with drug addiction. On the whole, this prejudice tends to be one-sided; only in the USA and Germany do the authors find that unvaccinated individuals feel some antipathy towards those who are vaccinated, although no statistical evidence of negative stereotyping or exclusionary attitudes towards these latter individuals were observed. Researchers also found evidence in support of discriminatory attitudes against the unvaccinated in all countries except Hungary and Romania and find that discriminatory attitudes are more strongly expressed in cultures with stronger cooperative norms.

You can read the paper here.

I can guess that the higher level of anger by the unjabbed to the jabbed in the U.S. is directly because the discrimination and intolerance imposed by the jabbed, such as Joe Biden’s shot mandates, violated what Americans consider their fundamental Constitutional rights. Who wouldn’t be hostile to someone who illegally cost you your job, your career, or even all your social contacts, because you didn’t want to get a COVID shot?

The study however is in general very depressing, because it tells us that the open-mindedness and toleration that was the hallmark of western civilization is largely gone. The future, built by the intolerant attitudes of today’s majority populations, will be a vicious and narrow-minded place.

NASA approves $1.2 billion asteroid-hunting space telescope

8:51 am

NASA has given the go-ahead to build NEO-Surveyor for $1.2 billion, more than twice the cost of its original proposal, to launch by 2028 and then look for potentially dangerous asteroids.

Notably, NEO Surveyor was earlier estimated to cost between $500 million and $600 million, or around half of the new commitment. The NASA statement said that the cost and schedule commitments outlined align the mission with “program management best practices that account for potential technical risks and budgetary uncertainty beyond the development project’s control.” Earlier this year, the project’s launch was delayed two years, from 2026, due to agency budget concerns.

The mission is designed to discover 90% of potentially Earth-threatening asteroids and comets 460 feet (140 meters) or larger that come within 30 million miles (48 million kilometers) of Earth’s orbit. The spacecraft will carry out the survey while from Earth-sun Lagrange Point 1, a gravitationally stable spot in space about 930,000 miles (1.5 million kilometers) inside the Earth’s orbit around the sun.

A prediction: It will cost more, and not launch on time. NASA’s decision to double the budget and delay the launch two years suggests it did not trust the JPL cost and time estimates. Based on most NASA-centered projects, however, it is likely the new numbers will still be insufficient.

Another space station company, ThinkOrbital, enters the competition

8:39 am

Though it failed to win a NASA contract to build its manned space station concept, the company ThinkOrbital has instead won small two research grants from the Space Force.

Earlier this year ThinkOrbital — with partners Redwire, KMI and Arizona State University — won two research contracts worth $260,000 under the U.S. Space Force Orbital Prime program for in-space servicing, assembly and manufacturing. Rosen said the plan is to refine the design concept for a space structure that could be used for debris removal and recycling.

“We’re working on a hub and spoke concept where smaller satellites would go out and gather the debris, bring it back to a central location, process it and we could either turn them into fuel or deorbit them,” said Rosen. “We could process debris at that hub, for example, and turn aluminum into aluminum powder that could be used for spacecraft fuel.”

ThinkOrbital is hoping to be selected for the next phase of Orbital Prime which could be worth up to $1.5 million.

This new concept would not be manned, but would instead be used by unmanned robots as service depot.

Today’s blacklisted American: Judge orders Philadelphia to stop blacklisting Christopher Columbus

12:48 pm

What Philadelphia thinks of Columbus
How Philadelphia wants Christopher Columbus honored

The modern dark age: A state judge has now ordered the city of Philadelphia to remove the plywood box that has covered its statue of Christopher Columbus for the past two years.

In her ruling, Judge Mary Hannah Leavitt said that if the city disagrees with the “message” the statue sends, it can add its own plaque with what it wants to convey. “More to the point, the City accepted the donation of the Columbus statue in 1876. It has a fiduciary duty to preserve that statue, which it designated an historic object in 2017. The Columbus statue is not City property as is, for example, a City snowblower,” the judge wrote.

On orders by the city’s Democratic Party mayor, Jim Kenny, the statue had been covered during the worst of the riots in 2020, with Kenny’s stated intention to remove it entirely at some point.
