Engineers shut lunar lander SLIM down in hope sunlight can recharge its batteries

Once they were able to download sufficient data, engineers have intentionally shut down Japan’s lunar lander SLIM in order to increase the chances it will recover should sunlight hit its solar panels and recharge its batteries.

The shutdown occurred three hours after landing on January 19, 2024, when the batteries still has a charge of about 12%.

Before turning the lander off remotely, mission control was able to receive technical and image data from its descent, and from the lunar surface. “We’re relieved and beginning to get excited after confirming a lot of data has been obtained,” JAXA said Monday in a statement, adding that “according to the telemetry data, SLIM’s solar cells are facing west”.

“If sunlight hits the Moon from the west in the future, we believe there’s a possibility of power generation, and we’re currently preparing for restoration,” it said.

The landing took place in the morning on the Moon, so there is a chance that in about a week, when the Sun shifts to the western sky, the panels will get sunlight and begin to recharge the battery.

Meanwhile, engineers confirmed that the two experimental mini-rovers were successfully deployed (see the media kit [pdf] for more details). At the moment we do not know if they have operated as planned, one rolling and the other hopping.

Iran launches another satellite

10:30 pm

Iran today claimed its second satellite launch in less than four months, placing a smallsat into an orbit its state-run press said was 466 miles high.

As yet this launch has not been confirmed by the U.S. military or any other sources. Like its previous launch in September, the information released is so slim it is unclear if the satellite is in orbit or not. This launch however used a new three-stage solid-fueled rocket dubbed Qaem-100, and from the image released, appears powerful enough to do the job.

Meanwhile, SpaceX once again scrubbed a Starlink launch, the third time in three days, due to weather, illustrating once again that despite the company’s almost clockwork ability to launch, its goal of reaching 150 launches in 2024 could be stymied simply by not having enough clear days where weather is not a problem.

6 SpaceX
5 China

Scientists finally look at prime samples captured by OSIRIS-REx of the asteroid Bennu

9:21 pm

The inside of OSIRIS-REx's sample return capsule
Click for original image.

Scientists have finally opened the sample capsule from OSIRIS-REx to see the prime asteroid material obtained from the asteroid Bennu during the spacecraft’s touch-and-go sample grab.

The captured material inside the capsule can be seen in the picture to the right. It is the debris inside the ring.

Erika Blumenfeld, creative lead for the Advanced Imaging and Visualization of Astromaterials (AIVA) and Joe Aebersold, AIVA project lead, captured this photograph of the open TAGSAM head including the asteroid material inside using manual high-resolution precision photography and a semi-automated focus stacking procedure. The result is an image that shows extreme detail of the sample.

Next, the curation team will remove the round metal collar and prepare the glovebox to transfer the remaining sample from the TAGSAM head into pie-wedge sample trays.

The final mass of material will be determined once it is removed and weighed, though the team has already recovered more than 70 grams that had clung to the outside the capsule, which in itself exceeded the mission’s targeted goal.

Ingenuity’s status uncertain but likely healthy

8:42 pm

Overview map
Click for interactive map.

Updates from the engineering team that operates the Mars helicopter Ingenuity in the past two days have suggested the helicopter might be in trouble. First the team issued a status update yesterday that indicated communications had been lost prematurely during the helicopter’s 72nd flight.

The flight was designed as a quick pop-up vertical flight to check out the helicopter’s systems, following an unplanned early landing during its previous flight. Data Ingenuity sent to the Perseverance rover (which acts as a relay between the helicopter and Earth) during the flight indicates it successfully climbed to its assigned maximum altitude of 40 feet (12 meters). During its planned descent, communications between the helicopter and rover terminated early, prior to touchdown.

A further update today said that communications had been regained, but also noted that the engineering team still did not have a full understanding of the helicopter’s status.

We’ve reestablished contact with the #MarsHelicopter after instructing @NASAPersevere
to perform long-duration listening sessions for Ingenuity’s signal.

Based on the information released (or lack thereof) from the previous flight, the 71st, it is my sense that the situation is not as dire as these reports suggest, and that the situation might simply be related to issues of communications. Let me explain why I have come to this conclusion.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

Today’s blacklisted American: Parents sue school and principal for punishing their son for being a football fan

1:30 pm

J. Ameduri
13-year-old J.A., prepped to cheer for his favorite
local high school football team

They’re coming for you next: The parents of a 13-year-old boy, identified only as J.A., are now suing the school principal who suspended their son for two days and banned him from all future sports activities because the middle-schooler had put on black “warrior” face paint under his eyes and on his cheeks, as football players often do and as shown in the picture to the right, in order to properly cheer for his football team at a game.

The principal of his school, part of the San Diego Unified School District, claimed it was “blackface,” though he never interviewed the boy, this companions, or anyone involved before issuing his banning edicts. For example, the boy had not even known what blackface was prior to this event. Moreover, no one at the game had complained or had been offended, and in fact, one black security guard joked with the boy, saying he should have made the spikes on the side higher, covering even more of his face.

“We’re suing the principal directly, the superintendent and then the people who made the decision to rubber-stamp the principal’s ridiculous decision to suspend J.A.,” Attorney Karin Sweigart said.

JAXA: SLIM soft landing successful but will likely die prematurely after landing

10:40 am

According to managers at Japan’s space agency JAXA, its SLIM lunar lander successfully completed its soft landing on the Moon.

It appears SLIM’s solar cells are not producing power. The spacecraft is presently on battery power, which will only last a few hours. Engineers are presently rushing to download images, taken during descent and after landing. There is also no word yet on whether the two test rovers were successfully released and achieved their test goals.

To precisely determine if the lander achieved its goal to hit a precise landing zone less than 300 feet across will require further analysis, much of which will depend on the images presently being downloaded. At the moment the engineers believe this goal was achieved, however, based on the telemetry already received.

Thus, it appears Japan has managed a soft-landing, something that in the past few years several countries (Israel, Russia, India, United States) and private companies (SpaceIL, Ispace, Astrobotic) have failed to do. Right now Japan appears to be the third nation to succeed in this new round of lunar exploration, joining China and India (which succeeded on its second attempt).

The next lunar landing attempt will be by the American private company, Intuitive Machines. Its Nova-C lander is scheduled for launch on a Falcon 9 rocket in mid-February.

SLIM lands on the Moon

9:00 am

Telemetry after SLIM's landing

According to telemetry data (as shown on the screen capture to the right), Japan’s SLIM lander has apparently landed on the Moon near Shioli Crater, proving its autonomous precision landing system worked as planned.

At the moment however Japan’s space agency JAXA has not yet confirmed that the landing was completely successful. After landing the announcers on the live stream repeatedly noted that though the telemetry indicated it had landed as planned, engineers had not yet confirmed that the lander was still operational. Note how the data to the right suggests the spacecraft is tilted slightly. This tilt appears to match the tilt of the surface, but it could also indicate a problem with communications.

A press conference announcing either a confirmation or a failure will begin shortly at the live stream above.

Chinese pseudo-company successfully completes rocket hop test

8:55 am

The Chinese pseudo-company Landspace successfully completed a rocket hop flight of its Zhuque-3 prototype hopper yesterday, testing vertical take-off and landing in preparation of recovering and reusing the first stage of its rockets.

The hop itself went to 350 meters and performed a small translation maneuver to the landing pad. The hope is called “ZQ-3 VTVL-1” which refers to “Vertical Takeoff – Vertical Landing”. It uses a single TQ-12 methane engine, which is also used on the current ZQ-2 rocket. The engine can throttle between 50-110% of the normal 80 tons of thrust, giving it a throttle range between 40 and 88 tons. The performed flight went on for roughly 60 seconds. The weight of the hopper is 50.3 tons.

Landpace confirmed the landing precision with 2.4 meters, with a landing speed of 0.75 meters per second, at a pitch angle of roughly 0.14 degrees, and a roll angle of 4.4 degrees. The hopper survived the hop and is already being inspected after the flight.

Video of the hop can be viewed at the link. The hopper is almost identical in concept to SpaceX’s Grasshopper test vehicle used by that company, flying with one engine of the same type used in its operational rocket.

If their test program continues as planned, Landspace hopes to begin flying reuseable stages in 2025, with that first stage capable of flying 20 times.

Of all the pseudo-companies in China, Landspace appears to be the most successful. It not only has an operational orbital rocket, Zhuque-2, that has carried satellites into orbit twice (here and here), it is very close to achieving rocket reuseability competitive with SpaceX.

Astrobotic’s Peregrine burns up in Earth’s atmosphere

8:23 am

At about 3:50 pm (Eastern) yesterday, the lunar lander Peregrine, built by the private company Astrobotic, hit the Earth’s atmosphere above the South Pacific and burned up, according to an update from the company.

The mission is over, having failed to reach the Moon due to a ruptured propellant tank caused by a leak in an interior helium tank.

The company was successful in regaining control over the mission after the leak, activating all payloads and getting data back from them, including images and even a short movie. It was also able to communicate with it from lunar distances. It failed however in testing its landing capabilities, its primary mission.

SpaceX successfully launches four astronauts to ISS on Axiom private mission

3:03 pm

They’re coming for you next: SpaceX today successfully launched three European astronauts (plus the company capsule commander) to ISS on an Axiom private mission, its Falcon 9 rocket lifting off from Cape Canaveral at 4:49 pm (Eastern).

The capsule, Freedom, is flying humans into space for its third time. The first stage successfully completed its fourth flight, landing back at Cape Canaveral.

The mission itself is private, but the customer is the European Space Agency, which has paid the company Axiom to bring its astronauts to ISS for a fourteen day mission. Axiom in turn hired SpaceX to provide the rocket and capsule. This flight is confirmation that Europe has accepted the concept of capitalism in space, whereby it no longer depends on governments to accomplish what it wants, but instead is a customer buying those products from the private sector.

The astronauts are expected to dock with ISS early tomorrow morning.

More academics demand that space activity be controlled and regulated, by them

1:13 pm

Modern academia: Marching with Lenin!
Modern academia, proudly marching with Lenin!

Yesterday I linked to a student newspaper article at the University of Alberta advocating more regulation over all space activity, focused on replacing private ownership with collective ownership while simultaneously imposing Marxist racial quotas to get rid “old white men”.

Today there was another story from academia demanding similar regulation. On January 12, 2024 there was a public panel discussion at Arizona State University (ASU), where four academics argued for the need for more government regulation of space. The description of the panel’s goals at the event’s website gives us a good hint of the goals of these academics:

Space exploration and utilization is a rapidly expanding sector, and there is growing consensus that the complex space governance system must evolve with it. Faced with this dynamic nature, in this fireside chat, with leading experts in space governance, policy law and space science, we present a clear framework for conceptualizing the space governance system as a tool for discussions on space law and policy, demystifying its structure and the actors, instruments and collaborations within it. We then consider key debates in the space policy field within this framework from a global and transdisciplinary perspective.

This is typically bad academic writing, designed to intentionally hide its meaning. One of the panelists however translated it most bluntly in this quote from article about the event:

Scientists: Evidence of large deposits of buried ice along Martian equator

10:24 am

Theorized buried ice deposits on Mars
Click for original figure from paper.

Using data obtained from Europe’s Mars Express orbiter, scientists believe they have detected evidence of a very large and extensive deposit of buried ice in the dry Martian equatorial regions, buried within the Medusae Fossae Formation, what is thought to be the largest volcanic ash deposit on Mars.

The blue-to-orange areas inside the Medusae on the map to the right, taken from figure 5 of the paper, shows where they have detected potential buried ice, at depths ranging from one to two thousand feet below the surface. The orange areas indicate the thickest ice deposits, as much as two miles thick. From the paper’s abstract:

The MARSIS radar sounder [on Mars Express] detects echoes in Medusae Fossae Formation deposits that occur between the surface and the base which are interpreted as layers within the deposit like those found in Polar Layered Deposits of the North and South Poles. The subsurface reflectors suggest transitions between mixtures of ice-rich and ice-poor dust analogous to the multi-layered, ice-rich polar deposits.

Assuming this detection is real, this would be the largest reservoir of potential water in the dry equatorial regions found yet, comparable to another similar buried detection deep below the giant canyon Valles Marineris but much larger.

Accessing this water however will not be simple, as it is deep underground. You couldn’t just drill a well, as it is ice, not a liquid water table. It would have to mined like minerals on Earth. There are uncertainties about this conclusion as well. It is possible the detection is not water but volcanic ash or dust compacted in a way that mimics an ice detection.

SpaceX files for permits to build a shopping center and restaurant at Boca Chica

9:44 am

SpaceX has now filed for permits to build both a shopping center and restaurant at Boca Chica, with construction beginning in March and completed by the end of the year.

The location proposed is on the beach only a short distance to the west of SpaceX’s Starship/Superheavy facilities. It will be located looking north not at the Gulf of Mexico but at South Bay, one of the large inlets that surround the spit of land where those facilities are located. It is also located on roads that might not close during launches, which means it might be an excellent location to attract tourists during launches, about six miles from the launch site itself.

The Japanese unmanned lunar lander SLIM, in orbit around the Moon since December 25, 2023, has now lowered its orbit in preparation for its lunar landing attempt, now scheduled for tomorrow, January 19, 2024, with operations beginning at 10:00 am (Eastern).

The image to the right indicates the targeted landing area near Shioli Crater. The mission’s prime engineering goal is to demonstrate precise robotic landing technology, able to land a spacecraft softly on another planet within a target zone less than 300 feet across. If successful it is expected to survive for about two weeks, studying the surface below it with a multi-spectral camera but also releasing two test probes, one a hopping rover and the second a rolling spherical rover. Both carry their own science instruments.

Astronomical high-altitude balloon flight now exceeds two weeks

9:14 am

GUSTO's flight path as of January 18, 2024

A high-altitude stratospheric balloon, dubbed GUSTO and designed to study the interstellar medium, has now been circling the south pole over Antarctica for fifteen days.

The map to the right shows its full flight path since its launch on December 31, 2023. From the press release:

GUSTO is mapping a large portion of the Milky Way galaxy and Large Magellanic Cloud to help scientists study the interstellar medium. The observatory is transmitting the data it collects back to watchful teams on the ground as it steadily circumnavigates the South Pole around 120,000+ feet.

GUSTO is flying on a 39 million cubic-foot zero-pressure scientific balloon, which is so large it could easily fit 195 blimps inside of it. The balloon is used to fly missions for long periods of time during the Austral Summer over Antarctica. GUSTO is aiming for a NASA record of 55+ days in flight to achieve its science goals.

You can follow GUSTO’s flight in real time here.

SpaceX requests 43 acres of nearby Boca Chica State Park, offering to expand another park by 477 acres

1:52 pm

In order to “expand its operational footprint” at Boca Chica, SpaceX is asking to buy 43 acres of nearby Boca Chica State Park, and will offer as part of the purchase 477 acres adjacent to the Laguna Atascoca National Wildlife Refuge several miles to the north.

The link above includes maps showing the relative location of the properties. According to the meeting agenda for the Texas Parks and Wildlife department (TPWD), scheduled to take up this exchange next week, the commission already favors the deal.

“This acquisition will provide increased public recreational opportunities including hiking, camping, water recreation, and wildlife viewing, and allow for greater conservation of sensitive habitats for wintering and migratory birds,” the TPWD agenda stated. The agenda concludes by stating that the Commission finds that the proposed exchange is in the best interest of TPWD.

The public has been invited to comment on the deal at the meeting. Do not be surprised if we have a riot at that meeting of leftist activists protesting this deal.

Nazi brown shirts destroying Jewish businesses on Kristallnacht
Nazi brown shirts destroying Jewish businesses on Kristallnacht

While there remains a shrinking percentage of Democrats who strongly believe in the law and the Constitution, the leadership of that political party is largely now controlled by those who believe otherwise.

Two incidents the past week illustrated this fact most starkly.

First a pro-Hamas protest in front of the White House on January 13, 2024 became so violent that many staffers inside the building were evacuated for their safety.

“During the demonstration near the White House complex Jan. 13, a portion of the anti-scale fencing that was erected for the event sustained temporary damage,” the statement read. “The issues were promptly repaired on site by U.S. Secret Service support teams.”

The U.S. Secret Service told Fox News Digital that some fences were damaged outside the White House, and that staff members and journalists were “relocated” as a result. “As a precaution, some members of the media and staff in proximity to Pennsylvania Avenue were temporarily relocated while the issue was being addressed,” the statement continued. “The Secret Service made no arrests associated with the march and there was no property damage to the White House or adjacent buildings.”[emphasis mine]

You can see video of these attempts to break into the White House here. Though the White House grounds were never penetrated, the violent self-righteous attitude of the mob is quite clear: They have the right to break in, because their cause is just. The law does not apply to them.

The highlighted words in the quote above provide a further explanation as to why this violence happened. » Read more

A rock tadpole on Mars

A rock tadpole on Mars

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on January 11, 2024 by the left navigation camera of the Mars rover Curiosity.

The picture was highlighted in yesterday’s update from the rover’s science team, describing the team’s upcoming geological goals for the next few days.

We have observed resistant, polygonal fractures/ridges in many recent bedrock blocks. There is much speculation among the team as to the origin of these features. Hypotheses have different implications for past environments, and the polygonal fractures are therefore of high interest. As well as the polygonal fractures, there are more continuous linear veins. The relationship between the polygonal and linear fractures can also help to inform our interpretations

You can see the polygonal fractures in the full image. The thin line of rock sticking up from the tadpole illustrates one of these continuous linear veins. The material that fills the vein is obviously more resistent to erosion, so as the wind (and maybe ancient ice or water activity) scoured the rock into its tadpole shape, the vein material remained.

College professors insist all private activity in space must be regulated, by them

10:32 am

Now that private enterprise and free civilians are beginning to fly missions to space, independent of the government, “an international team of experts” have published a paper that demands that all future private activity in space be strictly regulated. From an article in the student newspaper of the University of Alberta:

Private citizens or corporations that collect data or research in space pose unique ethical concerns, Caulfield said. Previously, space travel was “largely funded by the public purse.” For example, the National Aeronautics and Space Administration (NASA) receives its funding from the United States government. Publicly funded research has to follow certain rules and there is a degree of oversight, Caulfield explained. But, “if space flight is funded primarily or largely by private companies like Blue Origin [and] SpaceX, what rules do they need to follow?”

Caulfield is Timothy Caulfield, the Canada Research Chair in Health Law and Policy and a professor in the University of Alberta’s faculty of law. He is also one of the twenty co-authors of this paper, the authors of which somehow think that because they teach at colleges they have better ethics that the owners of private space companies. Not only do they want to establish strict rules over what can be done in space, they want all research and data to be open source. The private data obtained by missions paid for by others must be available to everyone, even if they didn’t do a damn thing to get it.

These control freaks also insist that commercial space must follow standards of diversity, inclusion, and equity.

“This has been for too long dominated by old white men,” [Caulfield] said. “We’ve got to change that.”

O joy! We are here to help you! These idiots have ruined the entire academic community, making colleges worldwide cesspools of bigotry and race hate. They now want to impose their Marxist ideals to commercial space, probably because deep down they resent the fact that others are doing it and they are incapable of accomplishing anything on their own.

That Alberta’s student newspaper is all-in on these foolish ideas is especially disturbing. The students appear to have been brainwashed to accept such stupidity, and since they represent the future, it tells us what that future will be like.

Next manned mission to ISS to launch tomorrow

10:12 am

The next manned mission to ISS, a private mission by the company Axiom carrying three European astronauts and commanded by an Axiom astronaut, is presently scheduled to launch tomorrow, January 18, 2024, at 4:49 pm (Eastern).

This is a private mission by Axiom, launched on SpaceX’s Falcon 9 and flying the astronauts in its Freedom Dragon manned capsule. This will be Freedom’s third flight to ISS. The launch was originally scheduled for today, but SpaceX scrubbed the mission today in order to give it “additional time allows teams to complete pre-launch checkouts and data analysis on the vehicle.” It appears during normal prelaunch checkouts engineers found the joints between the upper stage and the capsule were not tightened the proper amount. The company decided to replace the joints, which caused this one day delay.

The crew will spend up to fourteen days at ISS.

Webb confirms the unusual shape of early galaxies as seen by Hubble

9:52 am

Earth galaxies shapes, as seen by Webb in infrared
Click for original image.

The uncertainty of science: The infrared view of the Webb Space Telescope appears to have confirmed and even underlined the unusual shapes of many early galaxies as previously seen by the Hubble Space Telescope.

Researchers analyzing images from NASA’s James Webb Space Telescope have found that galaxies in the early universe are often flat and elongated, like surfboards and pool noodles – and are rarely round, like volleyballs or frisbees. “Roughly 50 to 80% of the galaxies we studied appear to be flattened in two dimensions,” explained lead author Viraj Pandya, a NASA Hubble Fellow at Columbia University in New York. “Galaxies that look like pool noodles or surfboards seem to be very common in the early universe, which is surprising, since they are uncommon nearby.”

The team focused on a vast field of near-infrared images delivered by Webb, known as the Cosmic Evolution Early Release Science (CEERS) Survey, plucking out galaxies that are estimated to exist when the universe was 600 million to 6 billion years old.

While most distant galaxies look like surfboards and pool noodles, others are shaped like frisbees and volleyballs. The “volleyballs,” or sphere-shaped galaxies, appear the most compact type on the cosmic “ocean” and were also the least frequently identified. The frisbees were found to be as large as the surfboard- and pool noodle-shaped galaxies along the “horizon,” but become more common closer to “shore” in the nearby universe.

The galaxies also appear generally far less massive than galaxies in the near universe, which fits with the Big Bang theory that says they had less time to grow.

The press release notes that the sample size is still very small, and further observations will be required to confirm whether these shapes are common in the early universe.
