Glacial evidence in the dry equatorial regions of Mars?

11:15 am

Is this evidence of glacial ice in the Martian dry equatorial regions?

Cool image time! The picture to the right, rotated, cropped, rotated, and sharpened to post here, was taken on June 3, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the eastern half of a six-mile-wide unnamed crater with a depth of about 1,500 to 2,000 feet from rim to floor.

What makes this picture significant is the patchy material in the center of that crater floor, some of which looks almost like very old peeling paint. It also resembles the kind of glacial features routinely seen in many craters poleward of 30 degrees latitude on Mars.

Is this another example of such glacial features? If so, its location is what makes it significant.

The results of one in four medical clinical trials are probably fraudulent or unreliable

9:11 am

In 2020 a researcher in Great Britain decided to analyze the raw data used by 500 medical clinical trials, and found that one in four contained fraudulent or unreliable data.

Carlisle, an anaesthetist who works for England’s National Health Service, is renowned for his ability to spot dodgy data in medical trials. He is also an editor at the journal Anaesthesia, and in 2017, he decided to scour all the manuscripts he handled that reported a randomized controlled trial (RCT) — the gold standard of medical research. Over three years, he scrutinized more than 500 studies.

For more than 150 trials, Carlisle got access to anonymized individual participant data (IPD). By studying the IPD spreadsheets, he judged that 44% of these trials contained at least some flawed data: impossible statistics, incorrect calculations or duplicated numbers or figures, for instance. And 26% of the papers had problems that were so widespread that the trial was impossible to trust, he judged — either because the authors were incompetent, or because they had faked the data.

Carlisle called these ‘zombie’ trials because they had the semblance of real research, but closer scrutiny showed they were actually hollow shells, masquerading as reliable information. Even he was surprised by their prevalence. “I anticipated maybe one in ten,” he says.

There is the real story, however.

Carlisle rejected every zombie trial, but by now, almost three years later, most have been published in other journals — sometimes with different data to those submitted with the manuscript he had seen. He is writing to journal editors to alert them, but expects that little will be done.

In other words, the peer-review medical community continues to allow fake research to be published, even when it has been warned that research is fake.

But of course, we must trust everything they tell us. They are SCIENTISTS, and we must “follow the SCIENCE!”

SpaceX to raise another $750 million in stock sale; earnings rise to $8 billion in ’23

8:49 am

According to anonymous sources, a new stock sale at SpaceX is likely to raise another $750 million because of enthusiasm on Wall Street for the stock due to the company’s growing earnings, which are expected to double to $8 billion this year.

Last week, CNBC reported that Elon Musk’s SpaceX valuation reached nearly $150B following an announcement of a stock sale by existing investors. According to a copy of the purchase offer sent by CFO Bret Johnsen, which CNBC obtained, the company has entered into an agreement with new and existing investors to sell up to $750 million in stock at a price of $81 per share. This represents a 5% increase from the previous secondary sale at $77 per share, which valued the company at approximately $140B. SpaceX has not provided any comments regarding the purchase offer.

Though the article does not say, that revenue comes from two sources, SpaceX’s rocket launches and its Starlink constellation. In the first case the company dominates the launch industry, because its launch price is so much cheaper than everyone else. In the second case, Starlink is producing so much revenue because Elon Musk forced the company to move fast and get its satellites in orbit quickly. Though both SpaceX and Amazon announced their internet constellations at about the same time, Amazon has still not launched any satellites, while SpaceX has more than 4,000 in orbit. This active and operating constellation has allowed SpaceX to grab market share that Amazon is now likely never to get, even when it begins launching.

All this makes SpaceX very appealing to investors, which is why its private stock price has gone up. It is also why it has been able to raise now almost $11 billion in private investment capital for building both Starlink and its Starship/Superheavy rocket.

Rocket Lab launches seven satellites; recovers first stage from ocean

6:46 pm

Rocket Lab today successfully used its Electron rocket to place seven smallsats into orbit, lifting off from New Zealand.

The first stage used parachutes to softly splash down in the ocean, where it was recovered for refurbishment and relaunch. As this stage is the first in which this full reuse will be attempted, the ability to refurbish the stage after its salt water swim remains the critical factor. We will not know its state until a complete inspection plus static fire engine tests are completed.

The leaders in the 2023 launch race:

47 SpaceX
26 China
9 Russia
6 Rocket Lab
5 India

American private enterprise now leads China in successful launches 54 to 26, and the entire world combined 54 to 45, while SpaceX alone still leads the rest of the world (excluding other American companies) 47 to 45.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

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

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

 

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

 

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

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Flat-topped Martian mesa

Flat-topped mesa on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, and reduced to post here, was taken on April 18, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows only one of many flat-topped mesas in a chaos terrain region dubbed Oxia Chaos.

The mesa top is about 540 feet above the floor of the canyon to the north, which in turn is about 840 feet below the flat terrain north of it. That flat terrain to the north is not part of the chaos terrain, however, but the northern rim of the plateau that surrounds the chaos. Moreover, this particular piece of rim is separating from the plateau, as shown near the top of this January 16, 2008 context camera image from MRO. At some point in the future it will break off and fall into that canyon and on top of this mesa.

California Democrats retreat on their effort to defend child slavers

12:34 pm

The Democratic Party: eagerly supporting pedophilia
The Democratic Party: caught in the act of eagerly
supporting pedophiles

Pigs fly! After initially killing a bill on July 12, 2023 that would have increased the penalties on child sex traffickers, the Democrats who completely control the California Assembly’s Public Safety Committee reversed course one day later and voted to advance the bill.

With a final vote of 6-0, including two abstentions from progressive Democrats, the bill now moves to the Appropriations Committee, after which, if it is approved, can move the bill to be voted upon by the entire State Assembly. If passed, SB 14 will make trafficking of minors a serious felony that would qualify under California’s three strikes law, which keeps dangerous, serial criminals off the streets, and make individuals convicted of the crime ineligible for early release. [emphasis mine]

I highlight the two abstentions by Democrats. Even after a nationwide uproar over their willingness to block harsh penalties on those who traffic young children for sexual slavery, these two Democrats, including Assembly Majority Leader Isaac Bryan (D-Los Angeles), still could not bring themselves to vote for the bill.

Nonetheless, the reversal by the rest of the Democrats on the committee marks a major event. » Read more

Chandrayaan-3 completes second orbital maneuver

9:32 am

Chandrayaan-3's mission profile

According to India’s space agency ISRO, its lunar lander/rover Chandrayaan-3 today completed second orbital maneuver, raising the spacecraft’s orbit around the Earth from 41,762 by 173 kilometers to 41,603 x 226 kilometers.

The graphic to the right shows the entire mission profile of Chandayaan-3. It still has three more orbital adjustments to make in Earth orbit before it does its trans-lunar-injection burn to send it to the Moon. Once it arrives in lunar orbit it will then have to make six orbital adjustments to lower its orbit before making the descent to the surface.

The lunar landing itself is presently scheduled for August 23, 2023.

An apparent rocket section washes up on Australian coast

9:19 am

What appears to be a section of India’s PSLV rocket washed up on the western Australian coast yesterday, though at the moment the identity of the wreckage as not been confirmed.

Dr Alice Gorman, an expert in the field of space archaeology, said she believes the object is a fuel cylinder that came from the the third stage of India’s polar satellite launch vehicle rocket (PSLV), as many have suggested on social media.

The article includes a picture of that stage in orbit during a 2017 launch, and the similarity is obvious. If true, its specific launch at present remains unknown, though it appears it could have been floating in the ocean for years, a fact that is surprising in itself.

SpaceX launches using its second Falcon 9 first stage on its sixteenth flight

9:14 pm

SpaceX tonight successfully launched 54 Starlink satellites into orbit, lifting off from Cape Canaveral.

The Falcon 9 rocket used a first stage flying on its sixteenth flight, landing successfully on a drone ship in the Atlantic. That is the second 1st stage in SpaceX’s fleet to complete that many flights. Both first stages completed their sixteen flights in only three years, which means that those two first stages have actually flown more times than the entire United States rocket industry did annually from 2000 to 2019. I don’t have a full count, but I suspect both stages have launched in those three years more satellites then the totals for almost all other nations, excepting possibly Russia and the U.S. Both probably allowed SpaceX to amortize the cost of those launches considerably, possibly as much as 90%.

Just remember: Rocket industry experts were insisting even as late as 2016 that it was impractical to make rocket stages reusable, that to make a profit “a partially reusable rocket would need to launch 35-40 times per year to maintain a sizable production facility while introducing reused hardware into the manifest.” Based on that calculation, these experts determined with utmost certainty that a partly reusable rocket — like the Falcon 9 — could never make a profit.

Elon Musk must have agreed, and decided he needed an extra profit center for the Falcon 9. Starlink has provided that profit center. It not only needs that many launches, and pays for them, its profit stream from its internet customers is already adding to SpaceX’s bottom line.

Regardless, Musk has proved these “experts” utterly wrong. I always thought they were talking through their hat, but had no way to prove it. Thank you Mr. Musk for proving the point.

Note too that the two fairing halves on this flight were also reused, completing their ninth and tenth flights respectively.

The leaders in the 2023 launch race:

47 SpaceX
26 China
9 Russia
5 Rocket Lab
5 India

American private enterprise now leads China in successful launches 53 to 26, and the entire world combined 53 to 45, while SpaceX alone now leads the rest of the world (excluding other American companies) 47 to 45.

And it is doing this with that impractical, unprofitable, and impossible reusable Falcon 9 rocket. Heh.

House committee imposes major cuts to Justice, FBI, Commerce

11:15 am

As had been suggested by its decision to not impose any cuts (or increases) to the NASA budget, the House appropriation subcommittee in charge of Commerce, Justice, Science-related agencies imposed all of the 28.8% cuts required by the House leadership on the Department of Justice, the FBI, and the Commerce department.

Overall, the bill appropriates $58.4 billion for programs under the jurisdiction of the committee, a $23.8 billion cut compared to the current fiscal year. It eliminates 14 “diversity, equity and inclusion” programs in the covered agencies, cuts spending on “wasteful” climate change programs, and saves more than $50 million by ending the Biden administration’s plan to replace auto fleets at the Department of Commerce and Department of Justice with electric vehicles.

According to the GOP summary, the Commerce Department would see a $1.4 billion cut in discretionary funding, and the Department of Justice would see a $2 billion cut. Federal science agencies together would face a $1.1 billion cut under the bill.

The FBI’s budget is to be cut $1 billion, or 9% (an actual cut, not a reduction in the increase in spending), with $400 million of that coming from salaries and expenses. It also forbids the agency from spending a dime on its planned dream of a new posh and palatial headquarters in the DC suburbs, twice the size of the Pentagon and costing more than $3 billion.

This is exactly what Republicans should have been doing for decades, and were too cowardly to attempt. If an agency of unelected employees in the executive branch abuses its power and causes harm to innocent citizens, something the FBI and the Justice Department have been eagerly doing since Trump became president, then it is the responsibilty and obligation of Congress to use its power of the purse to cut those agencies’ funding.

Even now, however, no one should be confident these cuts will end up in the final bill. This is only the recommendations of one subcommittee. There are still many Republican cowards in the full House, and even more in the full Senate, who will gladly team up with the Democrats (who are all in favor of the abuse of power and the harm to innocent citizens) to reinstate the cuts.

Nonetheless, this is a start. It indicates that we might finally have turned a real political corner towards reform.
