New data suggests muon is more magnetic that predicted

9:26 am

The uncertainty of science: New data now suggests that the subatomic particle called the muon is slightly more magnetic that predicted by the standard model of particle physics, a result that if confirmed will require a major rethinking of that standard model.

In 2001, researchers with the Muon g-2 experiment, then at Brookhaven, reported that the muon was a touch more magnetic than the standard model predicts. The discrepancy was only about 2.5 times the combined theoretical and experimental uncertainties. That’s nowhere near physicists’ standard for claiming a discovery: 5 times the total uncertainty. But it was a tantalizing hint of new particles just beyond their grasp.

So in 2013, researchers hauled the experiment to Fermi National Accelerator Laboratory (Fermilab) in Illinois, where they could get purer beams of muons. By the time the revamped experiment started to take data in 2018, the standard model predictions of the muon’s magnetism had improved and the difference between the experimental results and theory had risen to 3.7 times the total uncertainty.

Now, the g-2 team has released the first result from the revamped experiment, using 1 year’s worth of data. And the new result agrees almost exactly with the old one, the team announced today at a symposium at Fermilab. The concordance shows the old result was neither a statistical fluke nor the product of some undetected flaw in the experiment, says Chris Polly, a Fermilab physicist and co-spokesperson for the g-2 team. “Because I was a graduate student on the Brookhaven experiment, it was certainly an overwhelming sense of relief for me,” he says.

Together, the new and old results widen the disagreement with the standard model prediction to 4.2 times the experimental and theoretical errors.

That result is still not five times what theory predicts — the faux standard physicists apparently use to separate a simple margin of error and a true discovery — but it is almost that high, has been found consistently in repeated tests, and appears to be an unexplained discrepancy.

Not that I take any of this too seriously. If you read the entire article, you will understand. There are so many areas of uncertainty, both in the data and in the theories that this research is founded on, that the wise course is to treat it all with a great deal of skepticism. For example, the anomaly reported involves only 2.5 parts in 1 billion. While this data is definitely telling us something, but it is so close to the edge of infinitesimal that one shouldn’t trust it deeply.

Investigation: Top German scientist fabricated data

9:10 am

Fraud in science: A just released investigation has found that one of Germany’s most cited psychologists fabricated data in a government-financed study.

Hans-Ulrich Wittchen, one of Germany’s top psychologists and an expert in treating anxiety and phobias, is not shy about promoting himself. His email signature says he is a “highly cited researcher,” and with good reason. He has almost 1000 articles to his name, according to the Web of Science, and has racked up nearly 70,000 citations. He is an editor of Germany’s diagnostic and statistical manual of mental disorders—the bible of clinical psychology—and until 2017, he led a psychology research institute at the Dresden University of Technology (TU Dresden).

Yet his reputation is under fire after an investigation into one of his studies found evidence of manipulation—and elaborate efforts to cover up the misdeed. The investigation report, turned over to TU Dresden in February and obtained by Science, also shows Wittchen intimidated whistleblowers and pressured senior TU Dresden staff. The Federal Joint Committee (G-BA), a public health organization, is suing the company it paid to do the study. And the Dresden public prosecutor’s office is now investigating criminal charges related to the study.

Apparently the study only surveyed about 75% clinics on its list, and then simply copied data to complete the survey for the other clinics. Then Wittchen made veiled threats to investigators, manipulated documents to hide what had been done, and even tried to get two whistle-blowers fired, accusing them of doing the misdeeds.

This report illustrates a reality that few are willing to recognize. The science field is rife with corruption in the areas where government funds and government-employed scientists converge. The dishonest scientists are likely a very tiny minority, but they are often the ones who have pushed their way up to the most powerful posts, not by doing science but by playing the politics required to gain power. The result is that the science coming from the government institutions they run is now frequently suspect.

We have seen this in the past year in the world’s health agencies worldwide. Their leaders have repeatedly made statements concerning COVID-19 that simply have no backing in research, have no consistency, are repeatedly contradictory, and seem based on politics rather than data. This same problem has also exhibited itself for decades in the climate field, as well as many other sociological and medical fields.

The only long term solution that will really work would be to separate government from science, a goal that is likely unrealistic. At a minimum at least we should be trying to shift the government research money so that it goes to independent private companies on a case-by-case basis, rather than permanent government agencies that are run by the government.

Europe and China discussing future space cooperation

8:49 am

The new colonial movement: The heads of the space agencies of both Europe and China held a virtual face-to-face discussion on April 1st, discussing their space operations as well as the possibility of future cooperation.

Zhang Kejian, administrator of the CNSA, and new ESA Director General Josef Aschbacher, who entered the post March 1, discussed a range of topics according to a short CNSA press release (Chinese). The parties outlined upcoming activities, with China recently approving a 14th Five-year plan for 2021-2025, and discussed lunar and deep space exploration, Earth observation, and cooperation in ground station.

Josef Aschbacher tweeted after the meeting that he had congratulated Zhang on the Chang’e-5 lunar sample return mission, which in December 2020 delivered to Earth 1.73 kilograms of lunar samples from Oceanus Procellarum on the moon’s near side.

…Karl Bergquist, ESA’s international relations administrator, told SpaceNews that ESA and CNSA went over ongoing activities including telemetry, tracking, and control support activities for the Chinese exploration program.

Apparently Zhang raised the issue of Europe contributing to China’s proposed lunar base. Aschbacher made no commitments, though he later stated that while there is “no ESA stance on this topic”, he anticipates future discussions on the topic.

Some of this is similar to the recent discussions between NASA and China, focused on exchanging telemetry of various orbiters to avoid the possibility of collisions or interference with their operation. I would not be surprised however if Europe expands this conversation and joins China in its space plans. The U.S. is shifting from a government-run space program — which both China and Europe favor — to a commercial model mostly run by private enterprise. Under that model there will be less opportunity for European participation in American space projects.

OSIRIS-REx completes last close-fly of Bennu

12:39 pm

OSIRIS-REx today successfully completed its last close-fly of Bennu before it will fire its engines on May 10th and begin its journey back to Earth to return its samples.

During the flyby, OSIRIS-REx imaged Bennu for 5.9 hours, covering more than a full rotation of the asteroid. It flew within 2.1 miles’ (3.5 kilometers) distance to the surface of Bennu – the closest it’s been since the TAG sample collection event.

It will take until at least April 13 for OSIRIS-REx to downlink all of the data and new pictures of Bennu’s surface recorded during the flyby. It shares the Deep Space Network antennas with other missions like Mars Perseverance, and typically gets 4–6 hours of downlink time per day. “We collected about 4,000 megabytes of data during the flyby,” said Mike Moreau, deputy project manager of OSIRIS-REx at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Bennu is approximately 185 million miles from Earth right now, which means we can only achieve a downlink data-rate of 412 kilobits per second, so it will take several days to download all of the flyby data.”

While they will get images of the asteroid’s entire surface, the region scientists are most interested in is the Nightingale sample return site where the spacecraft grabbed its samples. To best understand the asteroid they need to have before and after shots, and this last fly-by gave them the latter.

Today’s blacklisted Americans: Anyone under 50 in Vermont who is not a minority

12:20 pm

14th amendment banned
We don’t need no stinkin’ 14th amendment in Vermont!

You want to get a COVID-19 vaccine shot in Vermont? Well, if you are not part of the new BIPOC community (Black, Indigenous, People Of Color) you have to go to the back of the bus.

This according to a decision by Vermont’s state government on April 3rd:

Governor Phill Scott, a Republican who voted for Joe Biden, explains. “If you or anyone in your household identifies as Black, Indigenous, or a person of color (BIPOC), including anyone with Abenaki or other First Nations heritage, all household members who are 16 years or older can sign up to get a vaccine!

Before this announcement the rules had limited vaccinations to all those over 50. The new rules opened up shots to everyone but whites over 16 years or older.

Perseverance as seen from orbit

11:03 am

Perseverance landing site prior to landing
Click for full image.

Perservance on the ground
Click for full image.

Cool image time! The two photos to the right show the landing site for the Perseverance rover in Jezero Crater on Mars. The first image was taken in 2016 by the high resolution camera on Mars Reconnaissance Orbiter. The second image was made available today in the monthly release of photos taken that camera on MRO.

The arrow points to a small white streak that is not visible in the 2016 photo. A closer look reveals that the streak is actually two fanlike white deposits expanding outward in opposite directions from a central point.

What we are seeing are the exhaust fans blown onto the Martian surface by the retro-jets on the Sky crane that was lowering Perseverance to the ground. The rover was put down at the centerpoint, and was still at that spot on March 2nd when this photo was acquired.

The highest resolution version of this image requires special software, so in this version you cannot see the rover itself. Nor can you see the Sky crane after it crashed landed or the parachutes.

The new photo was taken one week after the first high resolution image from MRO, as part of what will become a routine periodic monitoring of the site, along with obtaining mapping information for picking the rover’s upcoming route They will also probably use both images to try to locate both the Sky crane and parachutes, on the ground.

SpaceX successfully launches another sixty Starlink satellites

9:48 am

Falcon 9 today, with booster on 7th flight

SpaceX this morning successfully launched another 60 Starlink satellites, bringing the total number in orbit to more than 1,500.

The first stage, on its seventh flight, successfully landed on the drone ship. During SpaceX’s live stream they noted that every launch by the company this year has used a previously flown first stage. Both fairings on this flight were also reused.

The leaders in the 2021 launch race:

10 SpaceX
7 China
5 Russia
2 Rocket Lab

The U.S. now leads China 14 to 7 in the national rankings.

I have embedded SpaceX’s live stream below the fold. Because of the clear weather this was a particularly beautiful launch. The video during the landing of the first stage was especially spectacular, with the camera on the booster showing the entire landing.

Watching Ingenuity’s flight

8:35 am

NASA has now announced the planned flight time for its Ingenuity helicopter now on the Martian surface, including information for watching the live stream of the attempt.

A livestream confirming Ingenuity’s first flight is targeted to begin around 3:30 a.m. EDT Monday, April 12, on NASA Television, the NASA app, and the agency’s website, and will livestream on multiple agency social media platforms, including the JPL YouTube and Facebook channels.

I will embed the JPL live stream on Behind the Black when it goes live.

Meanwhile, Perseverance’s weather station is now functioning, providing its first weather reports from Jezero Crater.

[E]ngineers now have atmospheric data from three different locations on the Red Planet – Perseverance, Curiosity, and NASA’s InSight lander, which hosts the Temperature and Wind sensors for InSight (TWINS). The trio will enable a deeper understanding of Martian weather patterns, events, and atmospheric turbulence that could influence planning for future missions. In the near term, MEDA’s information is helping decide the best atmospheric conditions for the Ingenuity Mars Helicopter flights.

As Ingenuity achieved pre-flight milestones, a MEDA report from the 43rd and 44th Martian days, or sols, of the mission (April 3-4 on Earth) showed a temperature high of minus 7.6 degrees Fahrenheit (minus 22 degrees Celsius) and low of minus 117.4 degrees Fahrenheit (minus 83 degrees Celsius) in Jezero Crater. MEDA also measured wind gusts at around 22 mph (10 meters per second).

Those numbers are about normal for Jezero Crater at 18 degrees north latitude in the spring.

Chang’e-4 and Yutu-2 reactivated for 29th lunar day

8:28 am

Chinese engineers have reactivated their Chang’e-4 lander and Yutu-2 rover, beginning their 29th lunar day on the far side of the Moon.

As is usual from the state-run Chinese press, the article provides little other detail, other than stating that Yutu-2 ” will continue to move northwest toward the basalt distribution area located about 1.2 km away from the rover.” That’s about 3,900 feet. Based on Yutu-2 pace of moving about 100 feet per lunar day, it will be more than three years before it reaches that goal.

Study: a Martian crater lake fed by glacial run-off

1:19 pm

Map of crater lake and run-offs
From figure 1 on the research paper.

A new study of a 33-mile-wide Martian crater in its southern cratered highlands has found evidence that a lake had once existed on the crater floor, and was fed entirely by glacial run-off in a cold climate, coming from its interior walls, not from outside the crater.

In a study published in Planetary Science Journal, a research team led by Brown Ph.D. student Ben Boatwright describes an as-yet unnamed crater with some puzzling characteristics. The crater’s floor has unmistakable geologic evidence of ancient stream beds and ponds, yet there’s no evidence of inlet channels where water could have entered the crater from outside, and no evidence of groundwater activity where it could have bubbled up from below.

So where did the water come from?

The researchers conclude that the system was likely fed by runoff from a long-lost Martian glacier. Water flowed into the crater atop the glacier, which meant it didn’t leave behind a valley as it would have had it flowed directly on the ground. The water eventually emptied into the low-lying crater floor, where it left its geological mark on the bare Martian soil.

You can read the full paper here. The crater is considered very old, which means this evidence dates from a very early Mars when the climate was very different. As the scientists note in their conclusion:

Today’s blacklisted American: Whites at Cornell University

12:55 pm

The Civil Rights Act of 1964: repealed by Cornell
The Civil Rights Act of 1964: repealed by Cornell

Continuing my weeklong series documenting the modern bigotry of our culture, today’s bigot is Cornell University, who recently offered a segregated rock-climbing course that whites were forbidden to attend. From the course’s original description:

This class is for people who identify as Black, Indigenous, Latinx, Asian, or other people of color.

Moreover, that original course description made it very clear that the course was limited to such students only.

The original description gave no indication that BIPOC [Black, Indigenous People, Others of Color] students were the “special focus” of the course, instead of the only eligible category for enrollment. While [that original version] said students “will also talk about BIPOC individuals and groups in rock climbing,” that sentence was immediately followed by the restriction to “people who identify as” BIPOC.

Such a class would be illegal under both federal and New York state law.

SpaceX’s decision to build launchpad with Starship tanks proves the rocket will be cheapest ever built

10:10 am

Capitalism in space: The decision by SpaceX’s to build the tank farm for its Starship/Super Heavy launchpad at Boca Chica using Starship tanks, rather than inexpensive off-the-shelf storage tanks, strongly suggests that the company’s manufacturing facility for building those tanks makes them very inexpensive, and also suggests that the final rocket will be as cheap to launch as SpaceX has promised.

SpaceX is effectively taking identical rocket parts, slightly tweaking a handful of those parts, and turning what could have been a rocket into a propellant storage tank. This is significant because relative to all other rockets in history, even including SpaceX’s own Falcon 9 and Heavy, building storage tanks with unchanged rocket parts on a rocket assembly line would be roughly akin to hiring Vincent van Gogh to paint lane lines.

Ever since Elon Musk made the radical decision to switch from composite structures to stainless steel, Starship has always aimed to be radically different than any large rocket before it. Crucially, by using commodity steel, the CEO imagined SpaceX would be able to build Starships fairly easily and for pennies on the dollar next to even SpaceX’s exceptionally affordable Falcon 9. In the last 18 months, it’s become apparent that SpaceX has built a factory capable of churning out one or two massive steel rockets per month and is willing to consign at least four or five of those Starship prototypes to all-but-guaranteed failures for the sake of data-gathering and iterative improvement.

Technically, the most logical conclusion would be that Musk was right and that SpaceX has quickly developed the ability to build steel rockets larger than any other launch vehicle on Earth for perhaps just $5M or less apiece.

The analysis at the link is detailed and worth reading. If correct, this decision by SpaceX proves that Starship and Super Heavy will be the cheapest rocket ever flown, even though it will be the largest ever flown, and also completely reusable.

Russia’s first private space tourism company shuts down

9:54 am

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

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

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

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

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

Rocket startup ABL Space gets giant Lockheed Martin launch contract

9:40 am

Capitalism in space: Smallsat rocket startup ABL Space, which has yet to launch its first test rocket, has won a gigantic launch contract from Lockheed Martin for as many as 58 launches through 2029.

Under terms of the block-buy agreement between ABL Space Systems and Lockheed, the aerospace giant will purchase “up to” 26 launches through 2026 and as many as 32 additional launches through 2029. If the terms are fulfilled, this would come to 58 launches over the next eight years for ABL Space. In an industry where even a single launch contract often produces a news release, a contract for five dozen launches is unprecedented for a private company.

…The partnership will allow Lockheed, which builds large numbers of satellites for commercial customers, frequent and low-cost access to space. It is perhaps not a surprise that Lockheed selected ABL Space for its small launch needs, as Lockhead was an early investor in the launch company during a seed phase in 2019 and has continued to participate in additional rounds of fundraising. ABL has raised a total of $219 million to date.

Though Lockheed Martin is not ABL’s biggest investor, by being an early investor it has been involved in the development of ABL’s RS1 rocket from the start, which also means that Lockheed Martin was essentially buying its own rocket company to place the satellites it makes into orbit.

In fact, this decision falls into line with what appears to be Lockheed Martin’s long term corporate strategy. In 2017 the company opened its satellite-making factory with the satellites designed with standardized structures so that customers could pick and choose the design of their liking.

In 2018 it was revealed that the company was a key investor in Rocket Lab, while also participating in the creation of the United Kingdom’s first spaceport in Sutherland, Scotland.

It then decided to become a major investor in ABL, probably taking advantage of what it learned from Rocket Lab to improve the design. Now it plans to use that new rocket to launch a large number of the smallsats it is building in its factory.

Lockheed Martin is essentially copying SpaceX’s vertical integration strategy, whereby it owns or builds all aspects of its launch business. This allows it to reduce costs while controlling construction entirely. You cut out the middle man, and make your satellites cheaper to sell to others.

The first launch of ABL’s RS1 rocket was originally scheduled for the first half of this year, but has now been pushed back to the third quarter. If successful the company says it will follow it with two more launches before the end of the year, and very ambitious schedule.

Ingenuity survives first night on its own on Mars

3:17 pm

Completing another a major engineering hurdle, the Ingenuity helicopter successfully survived its first night on Mars, unprotected by the power and shielding of the Perseverance rover.

“This is the first time that Ingenuity has been on its own on the surface of Mars,” said MiMi Aung, Ingenuity project manager at NASA’s Jet Propulsion Laboratory in Southern California. “But we now have confirmation that we have the right insulation, the right heaters, and enough energy in its battery to survive the cold night, which is a big win for the team. We’re excited to continue to prepare Ingenuity for its first flight test.”

Engineers will spend the next two days fine-tuning Ingenuity’s thermal and power systems. Then on April 7th they will begin testing the helicopter’s rotary blades and their motors. If all goes right, the actual flight will occur on April 11th.

Colorful mesa in the Martian northern lowland plains

1:34 pm

Colorful mound in Martian northern lowland plains
Click for full image.

Cool image time! The photo to the right, rotated and cropped to post here and taken on January 15, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), shows the colorful top of a small mesa in the northern lowland plains of Mars and about 300 miles north of the planned landing zone for Europe’s Franklin rover, scheduled to launch in 2022.

What makes this mesa stand out is the bright and colorful areas on its slopes. The colors are false, but they indicate [pdf] certain things. The yellow is likely dust covered rock. The pinkish rock is also likely dust-covered, but made up of coarser material. The bluish strip running along the mesa’s northern slope is possibly frost or ice, not unlikely as this mound is at 25 degrees north latitude and was taken during winter. The slope faces north, which would put it in shadow much of the time during winter.

The colors however only hint at what is there.

Today’s blacklisted Americans: Coca-Cola’s racist policies that discriminate against whites

12:00 pm

Coca-Cola's bigoted company policy
Examples of the bigoted educational material
being pushed by Coca-Cola

This week is going to be racism week for my daily posts on blacklisting in today’s fascist culture. Each day I will highlight another example of modern racism by companies and governments against innocent people simply because they were born with the wrong skin color. And that skin color will be white, which is now the one kind of racism that the left now honors and demands, from everyone.

Our first bigot this week is the multi-national soda company Coca-Cola. Most of the news this past week or so has been focused on this company’s mindless decision to condemn Georgia’s new election law, based on Democratic Party lies and a refusal to even read the law.

However, let’s take a closer look at Coke’s bigoted policies, which are expressly designed to create a hostile work environment for anyone who happens to be white, solely based not on their performance but their skin color. The image above shows screen captures of just four slides from a Coke-Cola critical race theory training class, provided by a whistle-blower but later confirmed by the company as accurate.

Methane tank leak caused Starship #11 failure

9:24 am

Capitalism in space: According to Elon Musk, a small leak of methane from one tank caused the failure of the eleventh Starship prototype. From Musk’s tweet:

Ascent phase, transition to horizontal & control during free fall were good.

A (relatively) small CH4 leak led to fire on engine 2 & fried part of avionics, causing hard start attempting landing burn in CH4 turbopump.

This is getting fixed 6 ways to Sunday.

Meanwhile, prototype #15 is getting prepped for rollout to the launchpad (Numbers 12-14 were scrapped), and the first prototype of first stage Super Heavy is being assembled to testing. It is presently unclear when either will take place, though the company still has a target date of July for its first orbital launch. According to Musk, the first orbital prototypes of Starship will be those numbered 20 or higher.

“Those ships will be orbit-capable with heat shield & stage separation system,” Musk tweeted. “Ascent success probability is high. However, SN20+ vehicles will probably need many flight attempts to survive Mach 25 entry heating & land intact.”

Knowing those first orbital ships will likely not land properly raises the question as to where they will be aimed to come down. SpaceX now owns two retired floating oil platforms, and is preparing them for use by Starship/Super Heavy. It could very well be that test flights of prototype #20+ will take place to and from those pads, out in the ocean, so as to minimize any risk to populated areas. Doing so will also allow SpaceX to hone its procedures for moving these big spaceships to and from the platforms.

Resilience successfully moves from one ISS docking port to another

4:29 am

With four astronauts on board the Dragon capsule Resilience tonight successfully undocked from one docking port on ISS and redocked to a different port.

This was the first time an American spacecraft had accomplished this task. It was necessary to clear the docking port that the next Dragon capsule, Endeavour, will use to bring its crew to ISS, presently set for launch on April 22nd.

Russian astronauts have piloted Soyuz spacecraft between different ports numerous times, both on ISS and on Russia’s earlier space stations. Tonight’s transfer by Resilience however was done entirely on autopilot. The American astronauts could have taken over manually at any time, but the spacecraft did the entire maneuver on its own.

There is a certain irony in how the Russians have always done this maneuver, manually, and how Resilience did this, without any human intervention. From the 1960s through the entire space shuttle program Americans and all its astronauts strongly demanded that their spacecraft be piloted, by the humans on board, rather than being controlled by software or ground control. The Russians instead insisted, at least initially, that while their astronauts had the capability of doing all maneuvers manually, their software or mission control should run things. This difference seemed to nicely symbolize the down-up nature of America versus the top-down culture of Russia.

Things are now reversed. I wonder if that tells us anything about the two cultures today.

More leaks found in Russian Zvezda module on ISS

10:34 am

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

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

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

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

Ingenuity on the ground
Click for full image.

Perseverance engineers have now confirmed that the Ingenuity helicopter was successfully released below the rover earlier today, and the rover immediately moved away to expose the helicopter to sunlight so that its solar panels can charge its batteries.

The photo to the right, cropped to post here, was taken by one of Perseverance’s rear hazard avoidance cameras, shortly after the release and move. They will now begin about a week of check-outs to make sure Ingenuity is functioning properly, even as they drive Perseverance a distance away to a lookout point where it can safely observe the helicopter’s test flight on Mars, presently targeted for April 11th. If successful this will be the first powered flight ever achieved on another world.

Sunspot update: Higher than predicted activity continues

12:10 am

The uncertainty of science: Time for our monthly update of the Sun’s on-going sunspot cycle. Below is NOAA’s April 1, 2021 monthly graph, showing the Sun’s sunspot activity through the end of March 2021. I have annotated it as always to show the previous solar cycle predictions.

The higher than expected sunspot activity that has been occurring almost from the moment the ramp up to solar maximum began in 2020 continued in March. The numbers weren’t as high as they were in December and January, but they were still higher than the predicted sunspot number.

Falcon 9 upper stage debris lands on Washington farm

9:57 am

Falcon 9 helium pressure tank
Click for full image.

When a Falcon 9 upper stage broke up over the Pacific northwest last week apparently one of its interior helium pressure tanks, used to help push the fuel or oxidizer from the larger tank during launch, fell on a Washington farm and has since been recovered.

The image to the right is that tank, in what appears to be remarkable shape. From the article:

Composite-overwrapped pressure vessels, or COPVs, are standard components in Falcon 9 rockets. They’re designed to hold the helium gas that’s used to pressurize propellant tanks. COPVs are likely candidates to survive re-entry because they’re relatively lightweight and heat-resistant.

The tank has been returned to SpaceX, which I am sure is going to be very interested in studying its condition very thoroughly.

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

9:45 am

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

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

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

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