NSF to do environmental impact statement on TMT

July 20, 2022 8:48 am Robert Zimmerman

The National Science Foundation (NSF) has suddenly announced that it plans to complete a full environmental impact statement on the construction of the Thirty Meter Telescope (TMT) on Mauna Kea in Hawaii.

The National Science Foundation plans to host four meetings on the Big Island of Hawaii in August. It said it won’t decide on whether to fund the telescope until after it considers public input, the environmental review, the project’s technical readiness and other factors.

…The National Science Foundation must conduct a new study under U.S. law to invest in the project because it is part of the federal government. A report from the U.S. astronomy community last year said TMT planned to obtain 30% of the project’s estimated construction costs, or $800 million, from the U.S. government.

The timing of this announcement is most interesting, coming more than a year after NSF had decided to partly fund TMT and just shortly after the passage of a new law in Hawaii taking control of telescopes on Mauna Kea away from the University of Hawaii and giving that control to some of the activists protesting TMT. Why is this study suddenly necessary when it hadn’t seem necessary before?

I think this decision is another example of the Biden administration allowing the bureaucrats in the federal government to exercise their power. I also think it is linked with the new bigoted effort in government to always put racial concerns first — in this case tribal Hawaiians. It signals a decision by these federal bureaucrats to team up with those tribal Hawaiians that oppose TMT because it is “white” and “a symbol of colonialism” to kill it.

As I have been predicting for years, TMT will never be built.

Picking the Republican candidates to vote for in the Arizona August 2nd primary

July 19, 2022 2:04 pm Robert Zimmerman

Liberty enlightening the world

As the August 2nd primary approaches here in Arizona, it is now the time to make some preliminary decisions on who to vote for. Below are my recommendations for statewide office as well as my congressional district, followed by my reasoning behind each choice.

First, however, I must note that I consider the August primary for the Republican candidates to be the real election. No matter who is chosen in the Democratic Party primaries, I would consider that candidate to be captured by the communists and anti-American bigots who now run that party. Thus, I couldn’t vote for any, not without seeing some major house-cleaning and change. Since there is no evidence of any Democrats making any effort to do this, the only important decision I see for voters is to decide who is the least likely Republican to lie to us and actually do what they say.

Now for my personal candidate choices. To make these decisions, I did some research, using the links provided by Ballotpedia. With each candidate, I reviewed supplementing my knowledge of them from other reading by reviewing their websites. At a minimum I urge my readers to do the same, in whatever state they live in. Ballotpedia is a magnificent non-partisan resource. It doesn’t take long to do this work, and it gives you a better educated basis for making your decisions.

I also fully recognize that there are no guarantees, and that my choices here may change before August 2nd. Right now however, with the knowledge at hand, these picks are the best I can do. And as always I welcome further intelligent and informative comments from my readers below.

Perseverance gains a little height

July 19, 2022 11:47 am Robert Zimmerman

Click for full image.

Click for interactive map.

Cool image time! The photo above, rotated and cropped to post here, was taken on July 18, 2022 by the right navigation camera on the Mars rover Perseverance.

The view isn’t that remarkable, when compared to many other pictures from Mars. What makes it newly interesting is that it shows that Perseverance has gained a little elevation as it explores the base of the delta that flowed into Jezero Crater. It is no longer on the crater floor, but above it, though not by much.

You can see the far rim of Jezero Crater in the distance, obscured somewhat by the dust that builds up in the Martian atmosphere during the winter. You can also see the gentle left-to-right downward slope of material that flowed down from that delta some time in the past. Also, though the resolution isn’t good enough to show it, the helicopter Ingenuity probably sits somewhere near the center of this picture, just to the right of the nose of the biggest ridgeline.

The overview map on the right gives the context, with the yellow lines showing my estimate of the area viewed by the picture above. The blue dot is Perseverance, the green dot is Ingenuity. The red dotted line is my present guess as to the planned route of Perservance up onto the delta.

Relativity signs deal to launch Impulse Space’s missions to Mars

July 19, 2022 10:20 am Robert Zimmerman

Capitalism in space: The commercial rocket startup Relativity has now signed a deal with the orbital tug startup Impulse Space to launch at least one mission to Mars, possibly as early as 2024.

Impulse Space has announced that the company will launch the first commercial payload to Mars on board Relativity Space’s Terran R rocket. Under the new partnership, Relativity will launch Impulse’s Mars Cruise Vehicle and Mars Lander from Cape Canaveral, Florida, as part of an exclusive agreement until 2029.

The earliest anticipated launch window occurs between 2024 and 2025 and would make use of Relativity’s fully reusable Terran R rocket launching from Space Launch Complex 16 (SLC-16) at the Cape Canaveral Space Force Station.

Terran R is planned to complete the trans-Mars injection burn to place the cruise vehicle, carrying the lander, on a trajectory toward Mars. The cruise vehicle will then separate from the lander that, protected by an aeroshell, will enter the Martian atmosphere and attempt to propulsively land on the surface of the red planet.

To say that this plan is tentative is to state the obvious. First, Relativity has not yet launched its first rocket. It hopes to do so before the end of this year, but that rocket is the Terran-1, much smaller than the proposed Terran-R. Second, Impulse itself has not yet launched any tugs, though its founder, Tom Mueller, was the head engine development at SpaceX when it developed the Merlin, Draco, Super Draco, and Raptor engines. After leaving SpaceX he created Impulse Space to provide orbital and interplanetary transportation for others. It appears he has decided that an early Mars mission will be the best way to put his company on the map.

Long March 5B rolls to launchpad, carrying China’s next large space station module

July 19, 2022 9:59 am Robert Zimmerman

Long March 5B being rolled to launch site

China’s big Long March 5B rocket was successfully rolled to its launch site yesterday in preparation for a July 24, 2022 launch that will put China’s next large space station module, Wentian, into orbit.

The Wentian module, with a launch weight near 44,000 pounds (20 metric tons), will dock with the Tianhe core module on China’s Tiangong station in low Earth orbit. Chinese astronauts Chen Dong, Liu Yang, and Cai Xuzhe living on the Tiangong complex will monitor Wentian’s arrival, then become the first crew members to float into the station’s new module.

The launch this weekend will add the second of three large pressurized modules needed to complete the initial construction of the Tiangong space station. The Tianhe core module launched on a Long March 5B rocket in April 2021, and Chinese ground teams are preparing the Mengtian module for launch on a Long March 5B rocket in October.

The big question mark however concerning this upcoming launch is the central core stage of the Long March 5B, seen in the picture above surrounded by four strap-on boosters with Wentian stacked on top. In all previous Long March 5B launches, that core stage reached orbit, deployed its payload, and then crashed to Earth uncontrolled because its main engines could not be restarted. Will this core stage do the same?

The name of this particular Long March 5B also carries with it a new suffix, “Y3”. In the past when the Chinese added letters to a name it was because the rocket had been changed or upgraded in some manner. Furthermore, in March China did some static fire engine tests of what were suggested to be new engines for the core stage.

Developed by the China Aerospace Science and Technology Corporation, the engine is designed for the core stage of the Long March-5 carrier rocket series, which will be used to launch two lab modules of China’s orbiting Tiangong space station this year.

The long-range test, lasting 520 seconds, has verified the reliability of the engine, and there will be more than 20 experimental tasks that the rocket engine will undergo to further test its performance, the company disclosed.

Based on this meager information, it appears that China might have upgraded the core stage’s engines so they can be restarted and the stage’s de-orbit can be controlled so it crashes over the ocean, not over some random point of inhabited land. We shall have to wait until after the launch on July 24th to find out.

The May micrometeoroid impact on Webb’s mirror

July 19, 2022 9:37 am Robert Zimmerman

Figure 3 from report

In a detailed report [pdf] of Webb’s overall excellent operational status following its in-space commissioning, the science team also included an analysis of the May 2022 micrometeoriod impact on one segment of Webb’s mirror.

The image to the right, taken from figure 3 of the report, shows the remaining alignment error of Webb’s entire mirror, after alignment. Except for that one bright spot in the segment to the lower right, all of the segments show excellent alignment, well within the range predicted before launch. The bright spot however is from the impact, and suggests that one mirror segment is significantly damaged. From the report:

The micrometeoroid which hit segment C3 in the period 22—24 May 2022 UT caused significant uncorrectable change in the overall figure of that segment. However, the effect was small at the full telescope level because only a small portion of the telescope area was affected. After two subsequent realignment steps, the telescope was aligned to a minimum of 59 nm rms, which is about 5-10 nm rms above the previous best wavefront error rms values 7 . It should be noted that the drifts and stability levels of the telescope mean that science observations will typically see telescope contribution between 60 nm rms (minimum) and 80 nm rms (where WF control will typically be performed). Further, the telescope WFE combines with the science instrument WFE to yield total observatory levels in the range 70-130 nm (see Table 2), so the slight increase to telescope WFE from this strike has a relatively smaller effect on total observatory WFE.

In plain English, the impact while damaging has not seriously reduced the telescope’s predicted capabilities.

However, to be hit with this size impact so soon after launch is very worrisome, especially because Webb’s mirror is not housed in any protective tube like Hubble or most telescopes. From the report:

It is not yet clear whether the May 2022 hit to segment C3 was a rare event (i.e. an unlucky early strike by a high kinetic energy micrometeoroid that statistically might occur only once in several years), or whether the telescope may be more susceptible to damage by micrometeoroids than pre-launch modeling predicted.

The science team is presently trying to anticipate what might happen if the impact rate turns out to be much higher than expected, and what can be done to mitigate the degradation of the mirror should more impacts occur.

Russia may delay its Luna-25 lander again

July 19, 2022 9:10 am Robert Zimmerman

The landing area for Luna-25
The landing zone for Luna-25 at Boguslawsky Crater

According to Russia’s state run media, Roscosmos is considering delaying its Luna-25 lander again from September ’22 to sometime next year because of recently discovered issues with its landing system.

The launch of Russia’s lunar mission Luna 25 will most likely be pushed back to 2023 at the earliest because recent tests of its soft-landing device showed it failed to meet requirements, two sources in the space industry told TASS.

The Doppler speed and distance sensor made by the Vega Concern, part of the Rostech State Corporation, was tested in May and June and underperformed in terms of measurement precision, the sources said. The current precision would give 80% probability of a successful landing while the desired specifications call for a higher probability, which means either the device or the landing plan will have to be reworked.

The launch of this lunar lander has been delayed repeatedly, though the recently deposed head of Roscosmos, Dmitry Rogozin, had said as recently as late May that the September launch date was firm. It could very well be that with his removal the new head, Yuri Borisov, took another look and decided this new delay was necessary.

NASA delays launch of its VIPER lunar rover to over concerns about commercial lander

July 19, 2022 8:58 am Robert Zimmerman

VIPER's planned route on the Moon
VIPER’s planned route at the Moon’s south pole

In order to do more engineering tests of Astrobotic’s Griffin lunar lander, NASA has now delayed the launch of its VIPER lunar rover from November 2023 to November 2024.

NASA’s decision to pursue a 2024 delivery date results from the agency’s request to Astrobotic for additional ground testing of the company’s Griffin lunar lander, which will deliver VIPER to the lunar surface through CLPS. The additional tests aim to reduce the overall risk to VIPER’s delivery to the Moon. To complete the additional NASA-mandated tests of the Griffin lunar lander, an additional $67.8 million has been added to Astrobotic’s CLPS contract, which now totals $320.4 million.

Though the press release makes no mention of it, the launch of Astrobotic’s Griffin lander is partly dependent on the launch of Astrobotic’s first and smaller lunar lander, Peregrine, which was originally supposed to fly on the inaugural flight of ULA’s new Vulcan rocket, in 2021. That rocket’s first flight however has been delayed repeatedly because of delays by Blue Origin in completing development of the BE-4 rocket engine, to be used in Vulcan’s first stage. It is presently scheduled for early 2023, but that date remains tentative. This new delay of Griffin could be to make sure Peregrine flies first.

Regardless, this new budget increase means that the budget for Griffin has experienced a 62% cost overrun from its original $199 million number. This large increase in what is supposed to be a fixed price contract suggests that Astrobotic has been having some problems unstated by NASA, despite an inspector general report [pdf] that said all was going reasonably well.

Pushback: PA school board settles lawsuit and will pay $300K for censoring critics

July 18, 2022 12:15 pm Robert Zimmerman

Reaffirmed at Pennsbury, despite its school board’s hostility

Bring a gun to a knife fight: The Pennsbury school board in Pennsylvania has now been forced to pay $300K and fire its attorney, Peter Amuso, because that attorney silenced three different individuals during the open comments period at a school board meeting, simply because they were criticizing the board’s policies.

More details here. This quote describes how Amuso shouted down one of those speakers, Doug Marshall:

Marshall was interrupted by solicitor Peter Amuso for referring to the equity policy as the “equity and critical race theory policy,” which, Marshall is told, isn’t what it is officially called. … Marshall is later asked to stop speaking for sharing “irrelevant” information and violating Pennsbury School Board Policy 903, which states that members of the public can be asked to stop speaking for “lengthy, personally directed, abusive, obscene or irrelevant” comments.

“You’re now being disruptive and disorderly, you’re done,” Amuso can be heard telling Marshall as he objects to being cut off.

The board’s defeat in court was certain because a federal court has already ruled [pdf] that the board’s actions were unconstitutional.

UAE earmarks $820 million for space-related projects

July 18, 2022 10:40 am Robert Zimmerman

The new colonial movement: The government of the United Arab Emirates (UAE) announced yesterday that it has budgeted $820 million for its space program, with the first project to be a constellation of Earth observation satellites.

Its first project will be to build a constellation of advanced imaging satellites, to be named Sirb, an Arabic term for a flock of birds. They will be used for environmental and land usage monitoring, data collection, and analysis. “These small-scale satellites are more agile, faster to develop and more powerful – an indicator of the types of new generation systems that technology is now making possible,” Al Amari said, noting the satellite’s use of SAR (synthetic aperture radar) technology.

The goal is to launch the first satellite by 2025, with the constellation completed by 2028.

It is not stated how else this allocated money will be spent, since such a constellation of smallsats should not cost almost a billion dollars to build.

Chinese university tests hypersonic space plane

July 18, 2022 10:30 am Robert Zimmerman

fietian-1, Chinese spaceplane

According to social media reports, a Chinese university, Northwestern Polytechnical University (NPU), successfully tested on July 4, 2022 a prototype hypersonic prototype that uses both rocket and scramjet engines, as explained at this report:

What is particularly interesting about the launch of Feitian-1 is that it uses an RBCC [Rocket-Based Combined Cycle] engine to propel it to speeds in excess of Mach 5. An RBCC engine is a combination of an air-breathing ramjet, air-breathing scramjet, and ducted rocket. As the vehicle accelerates, the engine transfers from one mode to the next, allowing it to cope with air hitting the intake at greater and greater speed, and then becoming a pure rocket at top speed and very high altitudes.

The two images shown above are an attempt to get a sense of scale for this rocket. I think it is smaller than the Chinese wish us to believe, probably less than fifty feet tall, as stacked. Note the buildings in the right image. Other images showed no tower or strongback, also suggesting a small rocket. Moreover, all the released images hide the base of the rocket, suggesting there are attachments there the Chinese do not wish us to see, probably fuel and communications lines, all of which would help determine scale.

Finally, the upper stage, which I estimate to be no more than fifteen feet long, is purposely photographed from the side to hide its likely spaceplane appearance. This spaceplane look suggests this particular engineering research is at least superficially commercial and not military, connected more with the effort in China to develop hypersonic planes. That the Chinese government allowed this much information to be released also tells us that this particular prototype is not specifically military in nature.

This is not to say that the technology will not be adapted for military use. It certainly will be. NPU and its Institute of Spaceplanes and Hypersonic Technologies is also sanctioned by the U.S. government because of its ties to China’s military.

The US sanctions list frequently includes Northwestern Polytechnical University among the sanctioned entities from China. The University’s staff and students are not allowed to purchase or use commodities made in the US, including mathematical software.

Despite being a space plane test of the small prototype hypersonic rocket, this is the first reliable report from China that I have seen of such a suborbital test. Previous reports, despite being heavily touted by the U.S. military and accepted without question by the mainstream press, were unconfirmed and appeared untrustworthy. This report, showing proof of a suborbital test of what looks like a smaller scaled prototype I think gives us a more accurate picture of China’s present capabilities in this technology. They are moving fast, but are not there yet.

SpaceX completes 31st launch in 2022, matching its entire output in 2021

July 17, 2022 12:17 pm Robert Zimmerman

Capitalism in space: SpaceX today successfully launched 53 Starlink satellites with its Falcon 9 rocket, completing its 31st launch in 2022, matching the company’s entire output for all 2021 in only a little more than six months.

The first stage completed its 13th mission.

The leaders in the 2022 launch race:

31 Space
23 China
9 Russia
5 Rocket Lab
4 ULA

American private enterprise now leads China 44 to 23 in the national rankings, and the entire world combined 44 to 39.

SpaceX is targeting 60 launches in 2022. With the year just a little more than half over, it is setting a pace capable of achieving that goal.

NASA and Roscosmos finalize barter deal for flying astronauts to ISS

July 16, 2022 9:35 am Robert Zimmerman

As expected, mere hours after the firing of Dmitry Rogozin as head of Roscosmos, the Russians finally signed a barter deal with NASA for flying astronauts on each other’s spacecraft.

U.S. astronaut Frank Rubio will launch to the space station from Kazakhstan with two Russians in September. That same month, Russian cosmonaut, Anna Kikina, will join two Americans and one Japanese aboard a SpaceX rocket flying from Florida. Another crew swap will occur next spring.

No money will exchange hands under the agreement, according to NASA.

It appears that the firing of Rogozin by Putin signals larger strategic goals. Putin wants to defuse the tensions between the west and Russia, and this barter deal indicates Rogozin’s firing has achieved that aim, at least in space. Whether Roscosmos’s new head, Yuri Borisov, can regain Russia’s international commercial rocket customers is more questionable. Roscosmos under Rogozin proved to be a very unreliable partner. Regaining trust so that westerners will be willing to buy its services again could take decades.

Layered mesa on Mars

July 15, 2022 12:57 pm Robert Zimmerman

Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on May 26, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a mesa about three quarters of a mile in length that appears to be many-layered, from top to bottom.

The brightness of the mesa, compared to the surrounding plains, also emphasizes the different layers, though in this case it suggests two major epochs where the material being laid down in each was fundamentally different.

Or the difference could simply mean that the surrounding terrain is covered with dust, hiding its true color.

There is no question that winds in the thin Martian atmosphere have contributed to the erosion that formed this mesa, much like the buttes in the American southwest are shaped by winds. Whether water was a factor for this Martian butte is far less certain.

Pushback: Blacklisted small businessman sues Biden administration for its racist contracting policies

July 15, 2022 11:48 am Robert Zimmerman

Democrats as always dedicated to segregation!
Democrats: dedicated to the new segregation!

“Segregation today, segregation tomorrow, segregation forever!” Christian Bruckner, a Romanian immigrant who runs a small business that competes for government contracts, is suing the Biden administration for its race and gender quotas outlined in the $1.2 trillion federal infrastructure law passed late last year by Congress.

The Infrastructure Investment and Jobs Act, signed into law in November 2021, appropriated $1.2 trillion for new infrastructure projects. As part of this law, Congress authorized $370 billion in spending for roads, bridges, and other transportation projects. But the law contains a quota, requiring that at least 10% of all funding ($37 billion) go to small businesses owned by “socially and economically disadvantaged individuals.”

Federal regulations define “socially disadvantaged” as the following racial or ethnic groups: Black Americans, Hispanic Americans, Native Americans, Asian Pacific Americans, or Subcontinent Asian Americans. And women are deemed “socially and economically disadvantaged.” Small businesses owned by males who are not in these preferred racial groups cannot compete for this money. This would include not only businesses owned by white males, but also males whose ancestors are from many countries in Central and South America, North Africa, the Middle East, and North and West Asia.

Saudi Arabia signs Artemis Accords

July 15, 2022 10:31 am Robert Zimmerman

According to an announcement yesterday by NASA administrator Bill Nelson, Saudi Arabia has now become the twenty-first nation to sign the Artemis Accords, joining the growing American alliance to explore the solar system.

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

The accords were introduced by the Trump administration and are bi-lateral agreements between each nation and the United States. Their language is designed to protect property rights in space, and thus get around the limitations of the Outer Space Treaty. By signing up as many nations as possible, the accords are also creating this new American space alliance, which will be competing against the Chinese-Russian axis that opposes the accords.

Right now Germany and India remain the only major players in space who have not aligned themselves with either side. I expect Germany to eventually sign. India however appears to want to remain non-aligned.

Virgin Galactic leases facility in Arizona to build up to six of its reusable suborbital space planes

July 15, 2022 9:13 am Robert Zimmerman

Capitalism in space: Virgin Galactic announced on July 14, 2022 that it has leased a new facility in Mesa, Arizona where it will build up to six of its reusable suborbital space planes, with the goal of beginning commercial flights by late 2025.

The Delta class spaceship is Virgin Galactic’s production vehicle that is designed to fly weekly, supporting the Company’s target of 400 flights per year from Spaceport America. Based on current schedules, the first of these ships is expected to commence revenue-generating payload flights in late 2025, progressing to private astronaut flights in 2026.

The Company is currently selecting various suppliers to build the spaceship’s major subassemblies, which will be delivered to the new Mesa facility for final assembly. Virgin Galactic motherships will ferry completed spaceships to Spaceport America, New Mexico for flight test and commercial operation.

Combined with its recent contract award to Aurora to build two new motherships, it appears the management that replaced Richard Branson at Virgin Galactic has found that it can’t really proceed with commercial operations with the ships Branson left behind. Apparently the company is working to replace everything, and will likely delay commercial operations another few years in the process.

These decisions might be smart, but considering the company’s long history of endless delays, the buying public and the investment community might not be willing to tolerate more delays. It also remains very questionable there is enough business to justify its prediction of 400 flights per year, even if the company loses no customers.

Masten lays off staff, apparently shuts down

July 15, 2022 9:02 am Robert Zimmerman

Capitalism in space: The small lunar lander company Masten Space Systems, which for years has worked to develop vertical rocket landing technology and has a $75.9 million contract with NASA to put a rover on the Moon, has apparently furloughed its staff and shut down operations.

The XL-1 lander was originally scheduled to launch in December 2022 bound for a landing at the moon’s south pole. In June 2021, Masten announced an 11-month launch delay to November 2023. The company said the delay was caused by industry-wide supply chain disruptions and the effects of the ongoing COVID-19 pandemic.

CLPS partners are expected to supplement NASA mission funding by carrying payloads for other parties. The source who requested anonymity said that is where Masten’s mission ran into problems. “We ran out of money after grossly underbidding. The estimate was $105 million but I was told that we had found a 30 million dollar private customer who wanted to fly with us,” the source said.

However, that customer later pulled out the venture. Subsequent attempts to fill the gap failed, the source added.

Masten is one of four companies with similar NASA lunar lander contracts. The others, Astrobotic, Firefly, and Intuitive Machines, all have scheduled missions planned, all of which however have been delayed for a variety of reasons.

Rogozin removed as Roscosmos’ head

July 15, 2022 8:52 am Robert Zimmerman

Dmitry Rogozin, the head of Russia’s Roscosmos space corporation which controls the country’s entire aerospace industry, was fired yesterday and replaced by another former deputy prime minister, Yuri Borisov.

Don’t think Rogozin is out of favor with Putin however. Instead, it appears Putin wants his bull-headedness for running one of the regions Russia has conquered in the eastern Ukraine.

Following its tumultuous tenure as the head of Roskosmos, Rogozin was expected to move to the presidential administration and, possibly, lead it or “curate” the Russian occupation of the Eastern Ukraine, the independent Meduza publication reported.

I wonder if Rogozin’s removal is connected in any way with the ongoing negotiations between NASA and Russia’s foreign ministry for the barter agreement to allow the two to fly each other’s astronauts on each other’s capsules.

That agreement has been in negotiations and reviews for months by the two agencies as well as the U.S. State Department and Russian Foreign Ministry. NASA has long advocated for the agreement to enable what it calls “mixed crews” or “integrated crews” on spacecraft. That would ensure at least one NASA astronaut and one Roscosmos cosmonaut would be on the station should either Soyuz or commercial crew vehicles be unavailable for an extended period.

Rogozin’s bellicose manner has I think made those negotiations difficult. Putin might have decided, especially with the break up of its space partnership with Europe, to tone things down. Moreover, he might have realized that Rogozin’s contentious manner might be better put trying to take control of occupied Ukrainian territory.

Webb infrared image of Jupiter & Europa

July 14, 2022 3:36 pm Robert Zimmerman

Click for full image.

During the commissioning phase after deployment, the James Webb Space Telescope took images of Jupiter and several asteroids in order test the telescope’s instruments. The photo to the right, cropped and reduced to post here, shows both Jupiter and its moon Europa to the left.

Fans of Jupiter will recognize some familiar features of our solar system’s enormous planet in these images seen through Webb’s infrared gaze. A view from the NIRCam instrument’s short-wavelength filter shows distinct bands that encircle the planet as well as the Great Red Spot, a storm big enough to swallow the Earth. The iconic spot appears white in this image because of the way Webb’s infrared image was processed.

…Clearly visible at left is Europa, a moon with a probable ocean below its thick icy crust, and the target of NASA’s forthcoming Europa Clipper mission. What’s more, Europa’s shadow can be seen to the left of the Great Red Spot. Other visible moons in these images include Thebe and Metis.

The false color differences indicated differences in heat ~~but it is not explained whether brighter is colder or warmer in this photo.~~. As one of my readers below correctly notes, Europa’s shadow tells us that darker is cooler. This one image shows that the Red Spot and Jupiter’s equatorial regions and poles are generally warm.

July 14, 2022 11:22 am Robert Zimmerman

Academia: dedicated to segregation!
University of California: dedicated to the new segregation!

“Segregation today, segregation tomorrow, segregation forever!” The University of California has now joined with the University of Arizona in deciding that American Indians should be afforded special favored treatment above all other races and will therefore no longer have to pay tuition.

From the announcement letter [pdf], signed by the university’s president, Michael Drake:

Starting in Fall 2022, the University will ensure in-state systemwide Tuition and Student Services Fees are fully covered for California residents who are members of federally recognized Native American, American Indian, and Alaska Native tribes. This plan will be funded through a combination of existing State and University financial aid programs as well as other resources.

…The University of California is committed to recognizing and acknowledging historical wrongs endured by Native Americans. I am proud of the efforts the University has made to support the Native American community, including the creation of the UC Native American Opportunity Plan, and appreciate our conversations to date on all the ways in which we can better support Native American students. I am hopeful that this new program will benefit our students and continue to position the University of new program will benefit our students and continue to position the University of California as the institution of choice for Native American students. [emphasis mine]

For giving favored treatment to this special race of people, Drake has most generously decided that everyone else must pay for it:

Comet K2: big and doing unexpected things

July 14, 2022 9:19 am Robert Zimmerman

Link here. The article provides a nice overview of the observations so far of this very distant but very large comet making its suspected first close approach to the Sun this week, though still beyond the orbit of Mars and barely visible to amateurs.

K2 was first sighted in May 2017 at a much farther distance from the Sun than most comet discoveries. It had developed a coma much earlier than expected, which scientists now think came from from carbon monoxide.

“Carbon monoxide has been detected in other comets closer to the sun, although in much lower quantities than water. Carbon monoxide is very volatile and hard to freeze into a solid.” Jewitt and his colleagues theorized that as the comet slightly warmed while moving toward the planetary region of the solar system, the carbon monoxide ice near its surface turned into a gas that streamed into the vacuum of interplanetary space like constant wind. This wind stirred up dust particles from the comet’s surface, creating the round puffball-like coma.

But it took several failed attempts to measure the chemical composition of the comet to confirm the theory, Jewitt said. The team finally succeeded last year when the comet reached the orbit of Jupiter, and the scientists finally spotted carbon monoxide in the heart of the comet.

Comet K2 also did not develop a comet tail as expected. This appears to be because the particles in its coma are much larger than expected, something that at present is a complete puzzle.

No more Ingenuity flights until August

July 14, 2022 9:08 am Robert Zimmerman

Because it is now winter on Mars, with lots of seasonal dust in the atmosphere, the engineering team operating the helicopter Ingenuity have decided to suspend further flights until August.

Dust levels are expected to subside later in July, so the team has decided to give the helicopter’s batteries a break for a few weeks and build their daily state of charge back up. Weather permitting, Ingenuity is expected to be back in the air around the start of August.

This decision is not a surprise. When the team announced in May the plans for the helicopter’s most recent flight, completed in June, they suggested flights would pause for awhile thereafter. They have now made it official.
