China launches new rocket

9:06 am

The new colonial movement: The Chinese Academy of Science today successfully completed the first launch of Lijian-1, a new four stage solid fueled rocket, placing six satellites into orbit.

The Chinese state press announcement is here. I am using the name of the rocket from this source.

The rocket is an upgrade of a “road-mobile” ICBM, and can place two tons into orbit, making it the largest solid-fueled rocket in China’s arsenal of rockets. It launched from a pad built especially for it at China’s interior Jiuquan spaceport, which means it dumped its first, second, and maybe its third stages on Chinese territory.

The leaders in the 2022 launch race:

33 SpaceX
25 China
9 Russia
5 Rocket Lab
4 ULA

American private enterprise still leads China 46 to 25, and the entire globe combined 46 to 41.

Mike Oldfield – The Source of Secrets

6:01 pm

An evening pause: Actually, this is three pieces, “The Source of the Secrets,” “Secrets,” and “Far above the Clouds.”

Hat tip “t-dub” Tom Wilson.

I’d like one piece of feedback about this video. When you watch it embedded on Behind the Black, is the music interrupted by commercials? That happens when you watch on YouTube. I am curious it this happens when a song is embedded on another webpage.

The very end of an 800-mile-long Martian canyon
Click for full image.

Cool image time! While most geeks interested in Mars are familiar with Valles Marineris, the largest canyon in the solar system, Mars has other large canyons that while not a big are impressive in their own right. The picture to the right, rotated, cropped, and reduced to post here, shows us the very very end of one such canyon. Taken on April 19, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), it shows the easternmost spot where Cerberus Fossae begins. From here, this narrow fracture-caused canyon extends another 800 miles to the west, sometimes splitting into two or three parallel cracks, but always oriented in the same direction, slightly north of due west.

The overview map below provides the context and wider view.

Today’s blacklisted American: Pro-abortion terrorists vandalize 77 churches and pregnancy centers in last ten weeks

11:18 am

The apparent goal of the pro-abortion left
Genocide: The apparent goal of the pro-abortion left

Persecution is now cool! Since the leak on May 8th of the Supreme Court decision to overturn Row v. Wade, pro-abortion terrorists have vandalized 77 churches and pregnancy centers without a single arrest, even as these thugs gleefully brag about their violence on social media and are provided aid and comfort by Democratic Party politicians.

From the first link:

KTTH in Seattle reported, “As churches and pregnancy centers come under assault, Democrat State Senator Emily Randall (D-WA26) is celebrating the vandalism of a pro-life billboard in Gorst. “In a pre-produced Instagram video, Randall giddily reports that a pro-life message was decorated by a pro-abortion extremist. She smiles as she tells her constituents that she ‘had to pull over when I saw the decorated/corrected billboard.'”

Democrats have refused to stop the illegal protests at the homes of justices, even after a Democrat tried to assassinate a justice. Life News reported, “House Democrats Block Resolution to Condemn Violence Against Churches and Pregnancy Centers.”

New boss of Roscosmos confirms decision to leave ISS in 2024.

10:36 am

Yuri Borisov, the new head of Roscosmos, today confirmed that Russia will leave its partnership at ISS in 2024.

The decision to leave the station after 2024 has been made,” Yuri Borisov, appointed this month to lead the Russian space agency, Roscosmos, said during a meeting with President Vladimir Putin. He added: “I think that by that time we will start forming a Russian orbiting station.”

This announcement leaves several questions.

1. What will happen to the Russian modules on ISS? They cannot function on their own, so undocking them means they either must be de-orbited or attached to another station. Since it is more likely a snowman could exist on the Moon than the Russians launching a new station by 2024, the future of those modules must be negotiated.

2. What will the Russians do once out of this partnership? As I said, they will not be able to launch a new station by ’24. In fact, it is more likely they won’t be able to launch one at all, considering the pervasive corruption that permeates all levels of their technological society. It took them almost a quarter century to complete and launch the newest module to ISS, Nauka, with many many technical problems along the way.

3. Will Russia and China forge a closer alliance in space? I expect Russia will try to negotiate a partnership with China on its space station, but I doubt China will agree to any agreement that makes Russia an equal. It isn’t, and China has no interest in making believe Russia is.

4. Will this force an acceleration in the launch of the American private space stations now under construction? Hard to say. If we had a competent executive branch run by a clear-minded president, some action could be taken to help make this happen. The present Biden administration is neither competent nor clear-minded, so I do not expect much from it. Managers at NASA however might be able to push for increased funding to speed development, but even if successful that carries risk. It will make the private stations more beholden to the government, thus lessening their independence.

All in all, a most interesting situation.

Childhood vaccinations in ’20 and ’21 declined the most in 30 years

9:36 am

Surprise! According to WHO data, the number of children receiving effective vaccines for serious known diseases declined in ’20 and ’21, dropping at a rate larger than seen in 30 years.

Data collected by the World Health Organization (WHO) and the United Nations children’s charity UNICEF show that the percentage of children who received three doses of the vaccine against diphtheria, tetanus and whooping cough (DTP3) decreased by 5 percentage points between 2019 and 2021, to 81% worldwide (see ‘Childhood immunizations decline’). DTP3 is considered to be a marker of vaccine coverage; if children miss these jabs, they’re probably also missing out on crucial vaccinations for many other diseases.

The report found that in 2021, 25 million children missed out on routine immunizations against diseases such as measles — leading to avoidable outbreaks. “If this downward trend continues, we can expect to see more cases, outbreaks and deaths from diseases which are completely preventable,” a WHO spokesperson told Nature.

This article, from the very leftist science journal Nature, notes only that WHO attributes the decline to “supply-chain disruption, diversion of resources and lockdowns.” If fails to mention the loss of faith worldwide in vaccines in general, due to the hard push by WHO and other government health agencies to force the relatively ineffective and possibly harmful COVID shots on everyone.

The vaccines for measles, diphtheria, tetanus and whooping cough do work, but by lying about the effectiveness of the COVID shots, health agencies worldwide have lost their credibility. They have successfully convinced millions of parents to fear getting any vaccines, even those that really work and can prevent their children from dying.

Congratulations to WHO, the CDC, and all government agents worldwide! You have helped bring out the death of millions of children. Great work if you can get it.

OneWeb and Eutelsat sign merger deal

9:21 am

Capitalism in space: OneWeb and Eutelsat today confirmed stories during the past few days to announce today that the two companies have signed a merger agreement.

Eutelsat Communications (Euronext Paris: ETL) and key OneWeb shareholders have signed a Memorandum of Understanding with the objective of creating a leading global player in Connectivity through the combination of both companies in an all-share transaction. Eutelsat will combine its 36-strong fleet of GEO satellites with OneWeb’s constellation of 648 Low Earth Orbit satellites, of which 428 are currently in orbit.

The deal still needs regulatory approval, but if this is granted it should be finalized by the first half of ’23.

UAE names astronaut to fly on six month commercial ISS mission, purchased from Axiom

Sultan Al Neyadi in training
Sultan Al Neyadi in training

Capitalism in space: The United Arab Emirates (UAE) yesterday announced that 41-year-old Sultan Al Neyadi will fly on six month ISS mission, launching in the spring of 2023. purchased from Axiom.

The UAE purchased a seat on the Falcon 9 rocket from Axiom Space, a space infrastructure development company in Houston. This is the Falcon 9 seat that Axiom Space was given by Nasa after the company gave up its Russian Soyuz rocket seat for American astronaut Mark Vande Hei in 2021.

MBRSC did not disclose how much they paid Axiom for the seat, but the agreement includes transport to and from the space station; comprehensive mission support; all necessary training and preparation for launch; flight operations, landing and crew rescue services.

The deal behind this seat is very complex. Essentially, Axiom paid for the seat of Mark Vande Hei’s flight on a Soyuz capsule from 2021 to 2022 (because NASA had no authorized funds to purchase that seat), and got a later seat on a Dragon for an Axiom commercial customer. It then signed a deal with the UAE for Al Neyedi’s flight in late April.

The result is the first long term commercial mission to space.

Al Neyadi has been in training for four years, and acted as the back up astronaut to the first UAE manned flight to ISS, purchased from the Russians in 2019.

Tentative crash date for Long March 5B core stage: July 31st

8:56 am

Predicted crash path of Long March 5B core stage
Click for full image.

Engineers from the Aerospace Corporation have now made the first preliminary calculations and determined that the core stage of China’s Long March 5B rocket that launched July 24th will crash to Earth uncontrolled on July 31, 2022, give or take one day.

The map to the right, reduced to post here, shows all the orbits during that 48 hour period. Note that, except for most of Europe, almost all the high population regions of the globe are in the crash zone.

This prediction is very tentative, and will change as the core stage’s orbit evolves in the next few weeks. It also could change entirely if China has updated the rocket’s engines so they can be restarted at least once to de-orbit the stage properly, as it has hinted it could do. If however the orbit begins to decay without any action by China, then we will know those hints were lies, and that China is once again violating the Outer Space Treaty by acting with willful negligence to threaten harm to others with one of its launches.

Dean Martin & Rick Nelson – Rio Bravo

6:01 pm

An evening pause: This medley of songs were performed as part of the Howard Hawks’ 1959 western Rio Bravo. The first song, “My rifle, my pony, and me,” was actually adapted from the main theme by Dimitri Tiomkin from Hawks’ earlier classic, Red River (1948). When Diane and I were watching this recently, I recognized the music, but it took a while to figure out where I’d heard it before.

Both movies are examples of the kind of entertaining and rich films Hollywood used to produce, routinely.

The corruption of medical science is surges on

12:32 pm

The modern basis of medical research in the dark age
The modern basis of medical research in the dark age

Three stories this past week clearly illustrate that the field of medical science — based on the philosophy to always seek the truth no matter where it leads — is now teetering on the edge of death, and might already have died.

First we have the revelation that a major 2006 paper on the roots of Alzheimer’s disease is likely fraudulent, its results fabricated.

The investigation uncovered evidence suggesting several instances of image manipulation in the work of Sylvain Lesné, a researcher working at the University of Minnesota and an author of the 2006 study. The paper, which is cited by more than 2,200 academic papers as a reference, launched interest in a specific protein called Aβ*56 [a beta-amyloid] as a promising target for early intervention in Alzheimer’s disease.

…Whistleblower Matthew Schrag, a neuroscientist at Vanderbilt University, first flagged his concerns about the images to the NIH on January 2022. Science asked two image analysis experts to review Lesné’s published work. They echoed Shrag’s concerns. They identified a total of 20 “suspect papers” authored by Lesné, 10 of which had to do with Aβ*56, per Science.

This discovery might also explain why there has been a 99% failure rate for all Alzheimer drug trials. Most of that work was based on Lesné’s work, specifically on his paper that pointed to amyloids.

Curiosity looks ahead

Curiosity looks ahead
Click for full resolution. For original images go here and here.

Overview map
Click for interactive map.

Cool image time! The panorama above, taken by one of the navigation cameras on the Mars rover Curiosity on July 23, 2022, forms a nice bookend to yesterday’s panorama. Yesterday Curiosity looked back at its past travels. Today it looks forward at where it is almost certainly heading in the days ahead.

On the overview map to the right, the yellow lines indicate the approximate area viewed by the panorama. The large red dotted line marks the rover’s original planned route, abandoned when the science team found the terrain on the Greenheugh Pediment too rough for Curiosity’s wheels. The smaller red dotted line is my present guess as to the rover’s future route to get back on course.

The flat-topped mountain dubbed Kukenán by the science team has probably been one of the prime goals of the entire mission, from the beginning. Its almost vertical face has innumerable layers, all of which record in great detail the geological history of Mars and Gale Crater. As noted by Abigail Fraeman from the Jet Propulsion Laboratory on June 30, 2022:

Kukenán’s Earth namesake is a tepui, or distinctive isolated table-top mountain, found in South America. The Martian Kukenán is also somewhat flat topped and an impressive expression in Mt. Sharp’s topography. While it looks like it’s about the same size as the hills that bound it in the above Navcam image (“Deepdale” on the left and the edge of “Bolivar” on the right), this effect is just due to forced perspective. In reality, Kukenán is nearly five times farther away and over three times as tall as Deepdale! Curiosity’s strategic traverse path takes the rover right past Kukenán in about a kilometer or so, so this feature will become a familiar landmark rising in our windshield for months to come.

The science team will likely park Curiosity in the saddle of the gap ahead for at least a week and spend a lot of time documenting that cliff face with multiple cameras, since at this location the rover will have an excellent view of that entire face. As it gets closer the angle looking up will get steeper, thus making viewing of the upper layers more difficult.

Long March 5B core stage from July 24th launch remains in orbit

8:50 am

According to data from the U.S. Space Command, the core stage of the Long March 5B rocket used to launch China’s next large module for its Tiangong space station is still in orbit, with no indication yet that China has the ability to safely de-orbit it over the ocean in a controlled manner.

From Jonathan McDowell’s Twitter feed:

Two objects cataloged from the CZ-5B launch: 53239 / 2022-085A in a 166 x 318 km x 41.4 deg orbit, 53240 / 2022-085B in a 182 x 299 km x 41.4 deg orbit. Orbital epoch of ~1200 UTC confirms that the inert 21t rocket core stage remains in orbit and was not actively deorbited.

In all previous Long March 5B launches the core stage reached orbit, deployed its payload, and then crashed back to Earth uncontrolled a few weeks later because its engines could not be restarted. Since it is large, pieces hit the ground, but fortunately nothing landed in habitable areas. In one case however had the return occurred fifteen minutes earlier it would have landed in the New York City metropolitan area.

There were comments made during the launch countdown by Chinese officials suggesting the stage’s engine can now be restarted to allow it to be de-orbited properly, but if so there is as yet no indication that this has happened. If anything, the presence of these objects in orbit suggest otherwise.

It is also possible Chinese engineers are doing further orbital tests with both objects, and will de-orbit them properly in the next week or so. That China conducted a series of static fire tests of this stage’s engines prior to launch strongly suggested that they can now control its re-entry.

Since China won’t say, however, we can only wait and watch.

OneWeb and Eutelsat negotiating possible merger

8:35 am

In a press release today the geosynchronous (GEO) communications satellite company Eutelsat revealed that it is negotiating a possible merger with the low Earth orbit (LEO) communications satellite company OneWeb.

The combined entity would be the first multi-orbit satellite operator offering integrated GEO and LEO solutions and would be uniquely positioned to address a booming ~$16bn (2030) Satellite Connectivity market. OneWeb is one of the two only global LEO networks and has experienced strong momentum over recent months, with service expected to be fully deployed in 2023.

The transaction would represent a logical next step in the successful partnership between Eutelsat and OneWeb, started with Eutelsat’s equity investment in OneWeb in April 2021 and deepened with the Global Distribution Agreement announced in March 2022. Eutelsat currently holds 23% of OneWeb’s share capital, alongside a consortium of high-profile public and private investors.

Under the terms of the transaction being discussed, Eutelsat and OneWeb shareholders would each hold 50% of the combined group’s shares. [emphasis mine]

This appears to be an attempt by Eutelsat to survive, since the future of geosynchronous communications satellites is presently very questionable with the arrival of the many LEO satellite constellations like OneWeb and Starlink.

Meanwhile, the highlighted words in the quote do not match reality. If anything OneWeb has stalled badly since February, when Russia invaded the Ukraine and cancelled the remaining half dozen or so scheduled OneWeb launches. OneWeb has announced new launch contracts with SpaceX and India, but because none have even been scheduled, it increasingly appears its constellation will not be operational by 2023.

Completely misunderstanding Trump’s influence in the Republican Party

12:30 pm

In a column today at PJMedia, Rick Moran discussed in detail the battle going on right now in Arizona for control of the Republican Party. On one side we have Donald Trump and the candidates he has endorsed, led by Kari Lake for governor and Blake Masters for the Senate. On the other we have establishment candidates endorsed by former vice president Mike Pence and Arizona governor Doug Ducey.

Right now, the polls indicated strongly that the Trump side in this battle is going to win the August 2nd primary, and Moran was attempting to pinpoint the fundamental beliefs behind this rift.

The split in the Republican Party in Arizona and almost everywhere else is not a fight over issues. It’s not even a fight over Trump. It’s a fight over the perception of the party and what it means to be a Republican.

Trump defines the party in terms of loyalty to Donald Trump. And Trump defines “loyalty” as the extent to which you support him — personally and politically. Many Republicans see nothing wrong with that. Others, like Pence, see that kind of cult of personality as unconservative and dangerous. They take a far more traditional view of the Republican Party and want a return to the GOP’s roots of supporting God, low taxes, and small government.

In other words, according to Moran, ordinary Republicans are voting for Trump due to hero-worship, while establishment Republicans oppose Trump because they think such hero-worship unhealthy.

Moran’s analysis appears to represent the thinking of many Republican pundits. It also represents an analysis that is so wrong and out of touch with ordinary Republicans as to be downright laughable.

People are not voting for Trump-endorsed candidates because a childish “loyalty” to Trump. They are voting for his candidates because — based on his actions as President — they strongly believe those candidates are actually going to keep their conservative promises should they win. Trump did keep his campaign promises, and it appears he is trying to find candidates who will do the same. He knows that Republicans are sick and tired of fake conservatives like Pence and Ducey and the Bushes, who for decades have repeatedly made big conservative promises during the campaign but then have stabbed those voters in the back the minute any Democrat screamed at them.

These fakers simply don’t fight, and in Arizona, it is very clear that the candidates whom Pence and Ducey have endorsed are just another bunch of fakers. As soon as they get into office, they will forget all their conservative promises, and team up with the Democrats to maintain the failing status quo.

This is why there is a rift in the Republican Party. The established party has been a failure, and the new upstarts being touted by Trump appear willing to change that. Republican voters have come to recognize that — thanks to Trump — and are now voting accordingly, which is why an enormous number of Republican incumbents have been defeated this primary season.

It is astonishing to find that conservative pundits still don’t recognize these facts. Not only will their blindness leave them repeatedly shocked when Trump candidates win, it makes it impossible for them to understand the true dynamics behind this election season.

Cool image time! Normally I’d be hiking today, but since it is raining in southern Arizona at every mountain location we might want to go, I am forced to imagine hiking on Mars instead. The photo above, cropped to post here, was part of a mosaic of images taken on July 22, 2022 by the right navigation camera on the rover Curiosity.

Curiosity had just completed several drives that had it skirt around those two boulders visible in the center of the picture, as shown in the inset in the overview map to the right. The yellow lines indicate the approximate area covered by the photo. The blue dot marks Curiosity’s present location. The larger red dotted line the rover’s original planned route, with the smaller dotted line my guess as to the route the science team now plans to take to return to that course.

The rim of Gale Crater can be seen in the far distance, about 20 to 30 miles away and largely obscured by the winter dust that presently fills the atmosphere.

The science team had hoped to get close enough to these two boulders to touch them with the rover’s instruments, but decided to keep away because of both appeared a bit unstable.

The new colonial movement: China on July 24, 2022 (China time) has successfully used its Long March 5B rocket to put into orbit its Wentian module, the next large section that will dock with the Tiangong station in the next day or so.

According to one announcer, the core stage will not crash to Earth in an uncontrolled manner, as in previous Long March 5B launches. However, this is China, and his statement cannot be taken at face value. We shall find out in the coming days if this is so, or whether the core stage will be a threat to habitable areas as its orbit decays.

China releases one photo of Phobos taken by its Tianwen-1 Mars orbiter

3:58 pm

Phobos as seen by Tianwen-1
Click to see original photo.

China today released a single photo of the Martian moon Phobos, taken by its Tianwen-1 Mars orbiter, to mark the second anniversary of the orbiter’s launch.

The English press release at the link conveniently did not provide the image to the non=Chinese world, but the Chinese language release did. That picture is to the right, reduced slightly to post here. Considering its disinterest in making it easy to find this photo for English speakers, it is intriguing that China included the English language name Opik for one crater.

Moreover, this single picture release illustrates the paucity of Tianwen-1 photos made available to the public by China. Very few have been released, and though eventually China has been making its raw data available, it has not been doing so in a manner that makes it easy for outsiders to access it.

Nonetheless, this is one of the best pictures of Phobos I have yet seen.

NASA’s safety panel questions NASA commitment to commercial space stations

10:18 am

We’re here to help you! Not surprisingly, members of NASA’s safety panel have once again expressed doubts about NASA’s ongoing effort to encourage a thriving private, competitive, and efficient commercial space industry, this time questioning the transition from NASA’s government-built space station, ISS, to privately-built and owned space stations, four of which are presently under development.

At a July 21 meeting of the Aerospace Safety Advisory Panel, members said they were concerned that commercial stations whose development is being supported by NASA were unlikely to be ready in time before the ISS is retired at the end of the decade, and that those efforts suffered from insufficient budgets.

Those plans, called Commercial Leo Earth Orbit (LEO) Destinations by NASA, “are on a precarious trajectory to realization on a schedule and within the projected resources needed to maintain a NASA LEO presence,” said Patricia Sanders, chair of the panel. “This is an area of concern for us.”

The panelists also questioned how quickly the stations would be man-rated (claiming NASA was not allocating enough time to do so) as well as whether NASA had enough work for four stations.

For the past decade this safety panel has consistently shown itself to be hostile to the new commercial space companies. It has never seen any safety issues or scheduling problems with NASA’s big SLS rocket. Nor did it notice Boeing’s significant software and valve problems on Starliner. Yet somehow, the work of SpaceX was dangerous (when it was not), and now these new stations, most of which are being built by new space companies, are equally unfit for use.

It is time to shut down this panel. Or at a minimum fire its present members and bring in new blood more willing to look at the entire space industry with a more objective eye.

A large majority of today’s college students think blacklisting is a good thing

12:14 pm

The user manual for the modern generation
The user manual for the modern generation

The modern dark age: Old-fashioned Americans, who believe in free speech and tolerance, often assume that the spate of cruel blacklisting stories that now dominate our society are merely the actions of a few isolated individuals who have happened to gain a position of power and are abusing it.

This assumption could not be more wrong. We are entering a future where blacklisting, censorship, and the abuse of power will become the norm, because apparently the new generation thinks such things are always justified, if they have been offended in any way. From a recent poll of 2,000 students at 130 colleges:

In one eye-opening finding, 74 percent of undergrads endorse the view that a professor who says “something that students find offensive” should be reported to the university. By a majority almost as lopsided, 65 percent believe that a fellow student who says something they consider offensive should be turned in. That informers’ mindset is especially pronounced among students who identify themselves as politically liberal, fully 85 percent of whom would report a professor who offends them. But even among self-identified conservatives, a solid majority, 56 percent, are of the same mindset. [emphasis in original]

Collapsed dunes in Jezero Crater

Collapsed dune on Mars
Click for full image.

Cool image time! The photo above, cropped and reduced to post here, was taken on July 20, 2022 by one of high resolution cameras on the rover Perseverance. It shows what appears to be a collapsed dune on the floor of Jezero Crater.

The arrows mark the highest dune ridge line that suddenly ends at a cliff, with the sand that is piled up at its base appearing almost like it flowed like thick mud outward away from that cliff. Apparently, that material broke off in one single event sometime in the past.

Note the many parallel lines pointing outward from the base of the cliff. These lines appear to reflect the internal structure visible in the cliff itself. Somehow, when that sand collapsed, it flowed away while retaining some of that structure.

When this collapse happened is unclear. I don’t think it has happened recently, since Perseverance’s arrival, but I could be wrong.

China rethinking its proposed heavy lift rocket to make it a Starship clone

Long March 9, now a Starship clone

Chinese rocket designers appear to be rethinking the proposed design of the Long March 9 heavy lift rocket that China is building, switching from an expendable clone of NASA’s SLS to a reusable clone of SpaceX’s Starship/Superheavy.

The original design had called for three expendable stages and four strap-on expendable boosters using kerosene fuel, and was targeting a 2030 launch. The new design is two reusable stages, with the first having 26 engines fueled by methane, and would launch by 2035.

The image to the right is a screen capture from a presentation given by a long time rocket designer in China, viewable here cued to this point. Note the two large rockets on the right. The smaller is a two stage version, while the larger is a three stage version. Both look remarkably like Starship/Superheavy.

Isar Aerospace signs deal to launch from French Guiana

9:37 am

Capitalism in space: The German smallsat rocket startup Isar Aerospace has now signed a deal with the French space agency CNES to use one of its launchpads in French Guiana for launches of its new Spectrum rocket.

The Diamant pad was built more than a half-century ago for the French rocket of the same name, but has been dormant for decades. CNES is now working to convert the facility into a multi-user site for small launch vehicles, and Isar is the first company the agency selected in an open competition to use the site.

Isar also has a deal to launch from Norway. As recently as seven months ago the company was claiming its first test launch would occur there before the end of ’22. All told, Isar has three different launch contracts and has raised almost $200 million in investment capital.

Draper wins NASA contract to put a lander on the Moon’s far side

9:28 am

Capitalism in space: NASA yesterday awarded a $73 million contract to the space company Draper to place a lander on the Moon’s far side by 2025.

The lander, called SERIES-2 by Draper, will deliver to Schrödinger Basin three experiments to collect seismic data, measure the heat flow and electrical conductivity of the lunar subsurface and measure electromagnetic phenomena created by the interaction of the solar wind and plasma with the lunar surface.

The mission is the eighth NASA has awarded to date as part of CLPS, but the first to go to the lunar farside. The only mission by any country to land on the far side of the moon is China’s Chang’e-4 mission, which successfully landed in Von Kármán Crater in January 2019 and deployed the Yutu 2 rover that remains operational today.

With this award, there are presently five American companies with contracts to put landers on the Moon, Intuitive Machines, Astrobotic, Firefly, and Masten. Masten however shut down operations recently. This new contract to Draper for almost the exact same amount that had been awarded to Masten appears to replace Masten in the program.
