No more Ingenuity flights until August

9:08 am

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.

New Hawaiian law takes control of Mauna Kea away from astronomers

9:01 am

A newly passed Hawaiian law has taken the management of the top of Mauna Kea away from the University of Hawaii and given it to a new community authority which will include many of the activists who have blocked the construction of the Thirty Meter Telescope (TMT).

The new Maunakea authority will include Native Hawaiians in decisions about how the mountain is managed, with an emphasis on mutual stewardship and protecting Maunakea for generations to come. The authority will have 11 voting members, one of whom must be an active practitioner of Native Hawaiian cultural traditions, and one of whom must be a descendant of a cultural practitioner who is associated with Maunakea. There are also spots for representatives drawn from astronomy, education, land management, politics and other fields.

“I’m very hopeful for the new entity,” says Noe Noe Wong-Wilson, a Native Hawaiian elder who has helped to lead road blocks on the mountain. “It is beyond my imagination of where we would be at this time, because we have fought so long to be heard.”

The University of Hawaii has managed most of the lands around the Maunakea summit since 1968, when the state granted it a 65-year lease to operate a scientific reserve focused on astronomy. Maunakea has ideal skies for astronomical observation, given its 4,200-metre height and its stable and dark night skies. The university now has to transfer all of its management duties, including a complex set of subleases, permits and other agreements, to the new authority by 1 July 2028. [emphasis mine]

From the beginning of the protesters against TMT I made several predictions, all of which are now coming true.

  • This is a power play by some activist protesters for money and power. The new law gives them that.
  • The Democratic Party that controls Hawaii utterly supports the protesters, and was working behind the scenes to aid them. The new law proves that.
  • TMT will never be built. This new law makes that prediction almost certain.
  • The real goal of the protesters will be the eventual shut down of all astronomy on Mauna Kea. This new law is the first step in that process.

Forget about TMT. It is dead, as are any new telescopes or upgrades on Mauna Kea. Sometime around 2028, when this new authority takes over, we shall begin to see demands for the removal of telescopes.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

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.

How the localized nature of Democrat vote tampering will influence the 2022 election

3:47 pm

Based on the ample evidence of election fraud, corruption, and vote tampering done repeatedly by Democrats nationwide during the 2020 election, we can expect these politicians and their minions to commit similar election crimes in the upcoming 2022 mid-term elections, especially because the effort by some Republicans to reform their state election systems in the key purple states was so effectively blocked by Democrats, by many quisling Republicans, and by a willing leftist press.

It is however important to understand where that election tampering was done in 2020 in order to understand the election fraud to come, as well as creating a strategy to prevent it. As real estate agents like to say, “Location is everything!”, and it appears this applies to election fraud as well.

Summary slide outlining Powell voter fraud allegations
The 2020 fraud in Democratically-controlled Fulton County (Atlanta), Georgia.

In 2020, in states that were purple and where the final result was in doubt, the Democrats took advantage of their total control of the local urban voting districts in those states — where there are very few Republican voters — to tilt the results. In such places (Philadelphia, New York, Atlanta, Detroit, Phoenix) the government is essentially a one-party Democrat operation. Many election districts in these cities have no Republican election judges at all. If the Democrats wish to commit election fraud, there is no one looking over their shoulder to question them, with some districts actually taking aggressive action in 2020 to illegally keep Republican poll watchers out.

Thus we saw strong evidence in all of these cities of pro-Democrat ballot-stuffing, of all types, from fake ballots to ballots counted multiple times to evidence the votes on the ballots themselves were changed by computer. The fraud however was strongly localized to these urban centers controlled by Democrats. The vote tampering was able to tilt the statewide results. but not the local contests.

For example, Democrat mayors in Wisconsin teamed up to have drop boxes placed illegally in unsupervised locations, where Democratic Party mules could stuff them with thousands of harvested ballots. The Wisconsin Supreme Court finally ruled on July 8, 2022 that these boxes were illegal, and violated the plain language of the state’s election laws:

July 12, 2022 Zimmerman/Bartholomew podcast

1:43 pm

I did a short twelve minute segment with Bill Bartholomew on the radio in Rhode Island yesterday, which I have embedded below. The subject was the James Webb Space Telescope. While discussing the scientific importance of its images, Bill also allowed me to explain why overall the $10 billion cost and twenty-year development of this telescope was a mistake, and that had the money been better used — building many smaller space telescopes — astronomy would have likely learned much more sooner.

Icy scarps in the high southern latitudes of Mars

Icy scallops in the high southern latitudes of Mars
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on May 30, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label “Patching Mantling Unit,” located at about 57 degrees south latitude in a region where scientists have found good evidence of near surface ice. The top layer, or mantle, is likely patchy because it has a high content of water ice and is sublimating away. That almost all the cliffs are south-facing, which in the southern hemisphere gets the least direct sunlight, supports this supposition. For example, in the crater at the bottom of the image the ice would have disappeared first from the north-facing interior rim slopes, with the sublimation slowly working its way northward. Thus we have that butte extending out from the north rim.

The global map below not only indicates the location of these scallops with the green dot, it illustrates the overall icy nature of most of the Mars.

Pushback: Doctor blacklisted by Twitter for citing peer-reviewed research threatens lawsuit

12:05 pm

Twitter's ban of Bostom's tweet

UPDATE: One day after this post was published, Twitter reinstated Bostom’s account, admitting he broke no rules. As Bostom noted in response, ““Twitter’s arbitrary COVID-19 Lysenkoism must cease, permanently.”

Bring a gun to a knife fight: Doctor and researcher Andrew Bostom, who was blacklisted by Twitter in June simply because he cited a peer-reviewed research paper that suggested the COVID shots impaired semen production, has now retained the same lawyer who successfully forced Twitter to reinstate Alex Berenson’s account after he had been similarly blackballed.

The banned tweet and Twitter’s account suspension are shown in the screen capture to the right. As Bostom notes at the first link above:

The tweet in question contained data from a recent peer reviewed publication in the journal Andrology, with the eponymous title, “Covid-19 vaccination BNT162b2 temporarily impairs semen concentration and total motile count among semen donors”.

The Journal Andrology is highly respected and published through a joint effort of American and European scientific associations, The study was a straightforward, serial analysis of young male Israeli semen donors evaluating the potential impact of Pfizer’s covid-19 mRNA vaccine on their sperm concentration (count), and related functional measures.

Berenson had been banned by Twitter for a similar tweet that summarized these obvious and now well documented facts about the COVID shots:

“It doesn’t stop infection. Or transmission,” he wrote. “Don’t think of it as a vaccine. Think of it – at best – as a therapeutic with a limited window of efficacy and terrible side effect profile that must be dosed IN ADVANCE OF ILLNESS.”

After more than a year, Berenson’s Twitter account was finally reinstated, with Twitter admitting that he had said nothing wrong and should not have been banned. The details of the settlement are under seal, so we do not know if Berenson also received monetary damages from Twitter.

The lawyer who represented him is now representing Bostom in an almost identical case. Bostom’s account shouldn’t simply be reinstated. Twitter should suffer some financial penalty for the improper banning, since it acted to limit the public distribution of his work, and likely caused him some financial loss.

Bostom is not only pushing back against Twitter’s blackballing. He has also exposing Brown University’s effort to hide the negative health effects of its COVID shot mandate on its students. According to Bostom’s research:

Ariane-6 mock-up installed at launchpad for tests

9:28 am

The European Space Agency yesterday announced that it has installed an Ariane-6 full scale mock-up at its launchpad in French Guiana in preparation for tank and launch procedure tests.

The Ariane 6 combined tests model is highly representative of the flight model. It consists of the core stage and the upper stage, which make up the central core, as well as three pylons shaped like the rocket’s solid boosters and a fully representative but inert mockup of the fourth booster.

The Ariane 6 combined tests model central core was precisely mated in the purpose-built launcher assembly building, where this task is carried out horizontally. Automated guidance vehicles then brought the assembled core to the launch and, working with the crane at the mobile gantry, raised it to its vertical position.

The date of the actual first launch has not been announced, though ESA has officially admitted that it will not occur this year as hoped.

Roscosmos forbids its astronauts from using Europe’s robot arm

9:19 am

In response to the final decision this week by the European Space Agency to officially end its cooperation with Russia on its ExoMars mission, Roscosmos today forbid its astronauts from using Europe’s new robot arm that was recently installed on the Russian Nauka module of ISS.

Russia’s crew onboard the International Space Station (ISS) will stop using the European ERA manipulator arm in response to the European Space Agency’s (ESA) refusal from cooperation on the ExoMars project, CEO of Russia’s state space corporation Roscosmos Dmitry Rogozin said on Tuesday.

“In my turn, I instruct our ISS crew to stop using the European Robotic Arm (ERA). Let [ESA Director General Josef] Aschbacher along with his boss [EU foreign policy chief Josep] Borrell fly to space and do at least something useful in their entire lives,” he wrote on his Telegram channel.

The arm was designed to work on the Russian part of ISS, so it appears this decision by Rogozin is an example of someone cutting off his nose to spite his face. It essentially reduces Russia’s capabilities on the station.

As for ExoMars, it is unclear what will happen to the lander that Russia built to put Europe’s Franklin rover on Mars. Roscosmos has said it might proceed with its own mission to Mars, using that lander, but it has not made the full commitment to do so.

ABL completes static fire test of first stage of its new RS1 rocket

9:06 am

Capitalism in space: The new smallsat rocket startup ABL has successfully completed a full static fire test of the first stage of its new RS1 rocket from its launchpad in Kodiak, Alaska.

Company executives said that they performed the static-fire test of the first stage of its RS1 rocket July 9 at the Pacific Spaceport Complex – Alaska on Kodiak Island, the site where the company plans to conduct its first launch.

“The operation verified our startup sequence and stage level engine performance,” Harry O’Hanley, chief executive of ABL, said in a statement to SpaceNews. “A testament to our team’s intense preparation, we completed the test on the first attempt.”

The static-fire test also verified the performance of the ground systems, including a portable launch stool that can be packed into a shipping container. That system, O’Hanley said, enables launching from a flat pad like at Kodiak.

The company is presently completing testing of the rocket’s upper stage, with its next task to mate the two and complete a full dress rehearsal countdown. Though no launch date has been set, the company has been targeting a launch before the end of this year.

OneWeb agrees with SpaceX: Dish’s ground-based plans a frequency threat

9:01 am

Capitalism in space: In a filing with the FCC, OneWeb has come out in full agreement with its competitor SpaceX, stating that Dish’s proposal to use the 12 GHz wavelength would threaten its satellite communications.

In a letter to the Federal Communications Commission, OneWeb urged the regulator to reject a request from satellite broadcaster Dish Network and spectrum holder RS Access to run two-way mobile services in the band. If approved, “it would leave significant areas of the United States unusable by the otherwise ubiquitous NGSO [fixed satellite service] user terminals,” wrote Kimberly Baum, OneWeb’s vice president of spectrum engineering and strategy.

To connect user terminals, the SpaceX-owned Starlink and OneWeb megaconstellations use a satellite downlink band that extends from 10.7 GHz to 12.7 GHz. The analysis from OneWeb is the latest in a string of studies assessing how a high-power mobile network in the 12.2-12.7 GHz band would impact NGSO services.

Though the FCC has not yet made a final decision, it has already rejected Dish network’s request to block SpaceX’s use with Starlink of these wavelengths.

Rocket Lab & ESA complete launches

8:40 am

Very early today from New Zealand Rocket Lab successfully launched the first of two quickly scheduled launches for the National Reconnaissance Office, designed to demonstrate its ability to achieve fast scheduling and rapid turnaround. The second launch is targeting July 22, 2022, only ten days later.

Also today the European Space Agency (ESA) successfully completed the first launch of its new upgraded Vega-C rocket, putting its prime payload (a passive test satellite) plus six cubesats into orbit. Though ESA says it will eventually hand over operations to Arianespace, its commercial arm, the rocket itself is mostly built by the Italian company Avio. Also, the rocket’s solid rocket first stage will be used as an optional side booster on the Ariane-6 rocket ArianeGroup is building for ESA.

Though ESA launched Vega-C, as it will eventually be managed by Arianespace I include it in that company’s total, which is now three launches for 2022.

The leaders in the 2022 launch race:

29 SpaceX
22 China
9 Russia
5 Rocket Lab
4 ULA

American private enterprise. now leads China 42 to 22 in the national rankings, and the entire globe 42 to 38.

The highest point on Mars

The highest point on Mars
Click for full image.

Today’s cool image is cool not because of anything visible within it, but because of its location. The picture to the right, cropped to post here, was taken on May 27, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). While the terrain shown is a relatively featureless plain of craters and gullies not unlike the surface of the Moon, what we are really looking at is the peak of Mars’ tallest mountain, Olympus Mons.

That’s right, this spot on Mars sits about 70,000 feet above Mars’ mean “sea level”, the elevation scientists have chosen as the average elevation on Mars from its center. At 70,000 feet, this peak is more than twice as high as Mount Everest on Earth.

Yet you wouldn’t really know you are at this height if you stood there. The scale of this mountain is so large that this peak, which actually forms the southern rim of the volcano’s 50 to 60 mile wide caldera, is actually relatively flat. If you stood here, you would not see the vast distant terrain far below. Instead, you’d see an ordinary horizon line in the near distance only slightly lower than where you stand.

Today’s blacklisted American: Scientists questioning Big Bang theory protest censorship of their work

11:38 am

Webb's first deep field image
Nothing in Webb’s first deep field image shall be questioned, by anyone!

While the blacklisting described in today’s column has little to do with left vs right politics, it demonstrates clearly that the desire to silence dissent is now culturally pervasive across many fields. In science it has become especially toxic, as this story clearly shows:

Twenty-four astronomers and physicists from ten countries have signed a petition protesting the censorship of papers that are critical of the Big Bang Hypothesis by the open pre-print website arXiv. Run by Cornell University, arXiv is supposed to provide an open public forum for researchers to exchange pre-publication papers, without peer-review. But during June, 2022, arXiv rejected for publication on the website three papers by Dr. Riccardo Scarpa, Instituto de Astrofisica de Canarias, and Eric J. Lerner, LPPFusion, Inc. which are critical of the validity of the Big Bang hypothesis.

…[quoting the petition] “Without judging the scientific validity of the papers, it is clear to us that these papers are both original and substantive and are of interest to all those concerned with the current crisis in cosmology. It plainly appears that arXiv has refused publication to these papers only because of their conclusions, which both provide specific predictions relevant to forthcoming observations and challenge LCDM cosmology [the standard dark matter/dark energy Big Bang hypothesis]. Such censorship is anathema to scientific discourse and to the possibility of scientific advance.

“We strongly urge that arXiv maintain its long-standing practice of being an “open-access archive” of non-peer reviewed “scholarly articles” and not violate that worthy practice by imposing any censorship. Instead, we encourage arXiv to abide by its own principles, and publish these three papers and others like them that clearly provide ‘sufficient original or substantive scholarly research’ results and are of obvious great interest to the arXiv audience.”

Lerner and Scarpa had attempted to get their papers published in a peer review journal and had been stymied, apparently because the topic of their paper was inappropriate for that journal. They then decided to publish on arXiv, which has for almost three decades been open to the publication of all scientific papers written by credentialed scientists, as noted at the website:

India inaugurates its own space debris tracking facility

9:21 am

ISRO, India’s government space agency, today inaugurated its own space debris tracking facility, designed to track space junk much as the Space Force does in the U.S.

A new facility dubbed the System for Safe & Sustainable Operation has been inaugurated in Bengaluru that will deal with emerging threats from space debris.

The new facility will help India achieve its Space Situational Awareness (SSA) goals by providing comprehensive and timely information about the space environment. The system will alert the agency about probabilities of in-orbit collisions, fragmentation, atmospheric re-entry risk, space-based strategic information, hazardous asteroids and space weather forecasts.

Though China might have its own comparable facility, I am unsure. Even if it does, the U.S. military has been for decades the only nation that does this tracking and then provides the data to the world, at no cost. That India is now developing its own capability signals that nation’s desire to chart its own path in space that does not depend on the resources of others.

This facility also signals the shift in ISRO’s job. Before, this government agency built and owned India’s rockets, flying commercial missions for profit. Now, the Modi government wants to transfer those tasks to India’s private sector, with ISRO merely acting as a customer if it needs such services. This change however will reduce ISRO’s influence, something that factions within India’s government are resisting. By giving ISRO the new task of tracking space debris, the Modi government gives ISRO new responsibilities to replace the ones it is losing. This will ease the turf war and speed the transition to a competing commercial industry.

More Webb images released

9:08 am

Southern Ring Nebula, as taken by Webb
Click for full image.

As planned, NASA this morning released four new science images from the James Webb Space Telescope, in addition to the deep field image released yesterday.

All are spectacular, with each producing new information not previously observed. To see the Stephen’s Quintet image go here. For the exoplanet data, showing the presence of water in its atmosphere, go here. For the Carina nebula image, go here.

The image to the right, reduced to post here, shows the Southern Ring Nebula as taken by two Webb cameras in different infrared wavelengths. From the press release:

Two stars, which are locked in a tight orbit, shape the local landscape. Webb’s infrared images feature new details in this complex system. The stars – and their layers of light – are prominent in the image from Webb’s Near-Infrared Camera (NIRCam) [at the top], while the image from Webb’s Mid-Infrared Instrument (MIRI) on the [bottom] shows for the first time that the second star is surrounded by dust. The brighter star is in an earlier stage of its stellar evolution and will probably eject its own planetary nebula in the future.

In the meantime, the brighter star influences the nebula’s appearance. As the pair continues to orbit one another, they “stir the pot” of gas and dust, causing asymmetrical patterns.

Because this is an infrared image, the colors are not natural, but were assigned based on the slightly different infrared wavelengths produced by the object’s different features. From the image’s webpage:

Several filters were used to sample narrow and broad wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter.

Eventually astronomers will use Webb to look at many astronomical objects that Hubble has been observing for the past thirty years, adding a high resolution infrared view that will add to Hubble’s views.

Superheavy prototype #7 explodes during tanking test

8:37 am

Capitalism in space: SpaceX’s Superheavy prototype #7 exploded yesterday during a tanking test in Boca Chica, Texas.

I have embedded the video of the explosion below, cued to just before it occurred.

According to Musk, the engineering teams are presently assessing damage. The booster itself appeared relatively intact afterward, though leaning slightly to one side.

At a minimum this incident will delay the orbital launch attempt, especially if booster #7 must be replaced with booster #8, already being prepped in the assembly building nearby.

First science image released from Webb

3:40 pm

Webb's first deep field image
Click for original image.

The first science image from the James Webb Space Telescope has now been unveiled.

That image is to the right, reduced to post here. From the press release:

Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail. Thousands of galaxies – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe covers a patch of sky approximately the size of a grain of sand held at arm’s length by someone on the ground.

This deep field, taken by Webb’s Near-Infrared Camera (NIRCam), is a composite made from images at different wavelengths, totaling 12.5 hours – achieving depths at infrared wavelengths beyond the Hubble Space Telescope’s deepest fields, which took weeks.

The image shows the galaxy cluster SMACS 0723 as it appeared 4.6 billion years ago. The combined mass of this galaxy cluster acts as a gravitational lens, magnifying much more distant galaxies behind it. Webb’s NIRCam has brought those distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features.

The smeared concentric arrangement of many reddish objects surrounding the picture’s center strongly suggests we are seeing distortion by the gravity of this galaxy cluster.

While nothing in this image appears at first glance to be different than many earlier Hubble images, it looks at objects in the infrared that are much farther away than anything ever seen before, farther than Hubble in the optical could see. To understand the new discoveries hidden in such an image will likely take several years of further research. For example, before astronomers can understand what this image shows they need to determine the red shift of each galaxy, thus roughly determining its distance and the overall 3D structure of the objects visible. Moreover, the consequences of the gravitational lensing must be unpacked.

The White House briefing itself was somewhat embarrassing to watch, as Vice President Kamala Harris, President Joe Biden, and NASA administrator Bill Nelson all struggled to explain what this image shows, and failed miserably. Moreover, the briefing had technical problems, started very late, and it appeared that Bill Nelson especially had no idea what he was looking at. The briefing also ended very abruptly when it shifted to reporters’ questions.

Collapse pits on Mars

Elongated collapse pit on Mars
Click for full image.

Cool image time! The photo to the right, cropped to post here, was taken on May 21, 2022 and was today’s picture of the day from the high resolution camera on Mars Reconnaissance Orbiter (MRO). Dubbed “An Elongated Collapse Pit” by the science team, their caption explains:

This observation can help to tell whether or not there is a subterranean connection to this pit. As an added bonus, the much smaller depression to its south also appears to be another collapse pit.

This image had already been in my queue for a future cool image post, but since the scientists have posted it, it is time that I did as well.

In the inset I have brightened the image drastically to try to illuminate the darkest spots in both pits. The elongated pit appears to slope downward towards a hole in the southeast corner, while the interior of the second pit to the south remains completely dark. Both appear to suggest a void below that both reach.

The wider context image and overview map below shows that there is further evidence of more voids in this region of Mars, dubbed Ceraunius Fossae, because of its many north-south parallel fissures.

Today’s blacklisted American: Lake Superior State University bans free speech

12:17 pm

No first amendment allowed at Lake Superior State University
No free speech allowed at Lake Superior State University

The modern dark age: In June Lake Superior State University earned the Speech Code of the Month award from the Foundation for Individual Rights and Expression (FIRE) for having a vague and oppressive policy towards the placement of posters on campus.

Students wishing to put up posters on campus at Lake Superior State University better choose their words carefully, as the public university’s posting policy threatens “disciplinary sanctioning” over material deemed “offensive, sexist, vulgar, discriminatory or suggestive.” The trouble with this policy is that anyone, for just about any reason, can claim that someone else’s speech is “offensive” or “suggestive.”

Every month, FIRE highlights a university policy that hinders students’ free expression, and we’ve made Lake Superior State’s “Posting Policy” FIRE’s Speech Code of the Month for June.

FIRE’s main complaint about the college’s poster policy is that it is “overbroad” and “vague,” and could be abused to ban almost any speech. Students are thus forced to self-censor out of fear that any proposed poster he or she wishes to post could be deemed “offensive” and not only be banned, but cause the school to impose sanctions against the student.

The policy however is far worse. Note the highlighted phrases from that policy:

lacy Martian rock

Cool image time! Because the Curiosity team is presently conducting a drilling campaign at its present position in the lower mountains of Gale Crater, the rover has not moved in the past few weeks. At these times, the science team also has the rover’s other cameras do extensive surveys of the surrounding terrain, including high resolution mosaics by its high resolution camera.

To the right is one photo from the most recent mosaic, cropped to post here. It was taken on July 10, 2022, and shows one many layered rock on the ground near the rover. Though no scale is provided, I suspect the extended flake from this rock is somewhere between six to twelve inches long.

Another illustration of the alien nature of Mars. This flake could not exist on Earth, where the heavier gravity and atmosphere would have acted to break it.

Biden to unveil first Webb science image today

This should be entertaining: NASA today announced that the unveiling of the first science image from the James Webb Space Telescope has been moved up to later today, so that President Joe Biden can do the unveiling from the White House. From the NASA tweet:

We can’t contain the excitement for @NASAWebb’s first full-color images!

On Monday, July 11 at 5pm ET (21:00 UTC), President Biden will unveil one of the space telescope’s first images of deep space as a preview of what’s ahead.

It appears that the picture Biden will use in this photo op will be the only deep field cosmological picture scheduled for release:

SMACS 0723: Massive foreground galaxy clusters magnify and distort the light of objects behind them, permitting a deep field view into both the extremely distant and intrinsically faint galaxy populations.

The remaining four images will still be released on July 12, 2022, as originally planned.

The live stream of this event will be broadcast on NASA TV.

SpaceX launches another 46 Starlink satellites

6:49 pm

Capitalism in space: Using its Falcon 9 rocket, SpaceX today successfully launched another 46 Starlink satellites from Vandenberg Space Force Base in California.

The first stage completed its sixth flight, landing on the drone ship in the Pacific.

A minor note: SpaceX has clearly decided to simplify these broadcasts. Each is now starting much closer to launch, and the announcers have reduced their narration to the absolute minimum. Overall, this seems a wise policy, because though these live streams are good advertising, most of the people listening at this point do not need detailed explanations of everything. If anything, too much chatter is annoying, and as always less is more.

The leaders in the 2022 launch race:

29 SpaceX
21 China
9 Russia
4 Rocket Lab
4 ULA

The U.S. now leads China 41 to 21 in the national rankings, and the entire world combined 41 to 36. The forty-one launches in just over half of ’22 beats the U.S.’s total for the whole year just two years ago.

Elon Musk gives a tutorial on the Raptor-2 engine

6:16 pm

Tim Dodd of Everyday Astronaut on Friday released another video from his most recent tour of Starbase at Boca Chica with Elon Musk. I have embedded it below.

Essentially, this 41 minute video is Elon Musk giving us a tutorial on how SpaceX simplified and improved its Raptor engines from its first iteration to the present Raptor-2. He does this while standing in front of a long row of finished Raptor-2s, all meant for installation in the seventh prototype of Superheavy, the booster now on the launchpad with those engines installed and being prepared for its first static fire test prior to the orbital flight.

Musk revealed two interesting factoids during this video. First SpaceX blew up approximately 20 to 30 Raptor engines during the development phase, and melted the chambers on another 50. All of this was perfectly acceptable, because they designed engine manufacture so that a high production rate was built in. As Musk noted, “A high production rate solves many ills.” Losing engines during testing and development was no big deal because they were able to quickly replace them, with revisions and upgrades.

Secondly, Musk claimed that the Raptor-2 engine has a 99% efficiency, a level of efficiency that is unheard of in any engine for any purpose ever. I wonder if that claim will hold up as new companies and engineers work to beat SpaceX in the coming centuries.

A galaxy with swirling arms

A galaxy with swirling arms
Click for full image.

Cool image time! The picture to the right, cropped and reduced to post here, was released yesterday by the science team that operates the Hubble Space Telescope. It captures a galaxy about 520 million light years away that appears to have been reshaped due to a galaxy merger.

That merger somehow distorted the disk of the inner galaxy, the brightest area, while also producing two sweeping spiral streams in the surrounding periphery.

Despite its unusual shape, astronomers did not choose to study this galaxy. From the caption:

This observation is a gem from the Galaxy Zoo project, a citizen science project involving hundreds of thousands of volunteers from around the world who classified galaxies to help scientists solve a problem of astronomical proportions: how to sort through the vast amounts of data generated by telescopes. A public vote selected the most astronomically intriguing objects for follow-up observations with Hubble. CGCG 396-2 is one such object, imaged here by Hubble’s Advanced Camera for Surveys.
