Socialists win four Democratic primaries in Pennsylvania

10:07 am

At least they’re honest about who they are: Four socialist candidates won the Democratic Party primaries in Pennsylvania yesterday.

Two were in Philadelphia, and two were in Pittsburgh. Three of the four face no Republican opposition in the general election, which means there will be in increased polarization in the Pennsylvania state government. This also likely means that the governments of both cities will shift leftward. We can therefore reliably predict, as has happened in every place where socialists take power, that the quality of life in both Philadelphia and Pittsburgh will go down, even as both experience ballooning budgets and deficits.

Russian government audit finds $20 billion in “spending violations”

9:44 am

An audit by the Russian equivalent of the GAO has found more than $20 billion in “spending violations” within the government, most of which occurred in the defense and space sectors.

Other words for describing these “spending violations” might be “theft,” “embezzlement,” “misuse of funds,” or any number of more honest direct terms. The Russian government is simply very corrupt, and its culture includes the assumption by administrators and everyone else that it is their right to skim off as much as they can, for themselves.

Sadly, I do not see any reform occurring in the near future. This corruption is deeply ingrained, and the Putin government, also deeply entrenched, apparently likes it, as long as the thefts don’t become so obvious that nothing gets done, as happened at the new Vostochny spaceport during its construction.

Block 5 Falcon 9 first stage returns to port

9:35 am

SpaceX’s first Block 5 first stage for its Falcon 9 rocket, designed to fly a minimum of ten times, has returned to port after its first flight last week.

This is the most interesting detail revealed:

While not visible, the most significant improvements are likely to be found at the base of the first stage’s octaweb – now assembled with bolts instead of welds – in the form of a dramatically improved heat shield around its nine Merlin 1D engines (also upgraded, of course). One of the Falcon recovery technicians showed some exceptional interest in the shield and Merlins, likely documenting their condition in extreme detail to inform engineering reviews of the pathfinder rocket after its first flight test.

The pictures show those bolts quite clearly.

Mars cubesats take picture of Earth and Moon

12:36 am

One of the two MarCO cubesats heading to Mars on the first interplanetary cubesat mission, has taken its a picture of the Earth and the Moon.

NASA set a new distance record for CubeSats on May 8 when a pair of CubeSats called Mars Cube One (MarCO) reached 621,371 miles (1 million kilometers) from Earth. One of the CubeSats, called MarCO-B (and affectionately known as “Wall-E” to the MarCO team) used a fisheye camera to snap its first photo on May 9. That photo is part of the process used by the engineering team to confirm the spacecraft’s high-gain antenna has properly unfolded.

As a bonus, it captured Earth and its moon as tiny specks floating in space.

In a few weeks the two cubesats will make a mid-course correction, also the first time a cubesat has attempted such a thing.

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.

Redactions in Strzok/Page texts reveal FBI/Justice is hiding something

9:12 am

Link here. Essentially, the author did a very careful review of the texts between anti-Trump FBI officials Peter Strzok and Lisa Page during the week in July 2016 when the FBI investigation into Trump-Russian collusion began. What he found was that the many redactions in the texts serve only to hide what was really happening, as well as the extent of involvement in the Obama White House.

It would be interesting to know what is in the emails that apparently clarify how the Obama administration divided responsibility for running the Trump-Russia investigation. Just like it would be interesting to know what is behind all the many redactions in these texts about how and why the Trump-Russia investigation got started.

On what basis has the Justice Department concealed passages and references to government officials from these significant conversations? Are Justice and the Bureau claiming that the redactions are necessary because the information is classified — even though we’re talking about communications between highly trained intelligence officials?

And if that is the claim, are they telling us that Hillary Clinton was investigated — and given a pass — for the unauthorized transmission of classified information by FBI officials who were themselves actively engaged in the unauthorized transmission of classified information?

Based on past revelations, when we finally see what was redacted I expect we shall discover that the redactions had nothing to do with national security and everything to do with hiding malfeasance and the abuse of power by the FBI, the Justice Department, and the Obama administration.

Rogozin to take over Roscosmos?

8:48 am

I wonder if he used a trampoline: Less than a week after Putin dumped Dmitry Rogozin from his cabinet, a story in the Russian press suggests he has been offered the job as head of Roscosmos.

Under the government-run centralized Russian system, it would not surprise me if Rogozin gets this job. With the government, no one ever gets fired, they merely get shuffled about from one job to another. Results are irrelevant.

Another delay for SLS

8:36 am

This really isn’t news: Work on the core stage for the first SLS rocket launch appears to face another three month delay, threatening the scheduled June 2020 launch date.

The article outlines in great detail the work being done on the SLS core stage, and where the delays might be coming from, while also being vague about what exactly is causing the delay.

It is unknown if the additional time for completion of final assembly of the whole rocket stage is based on the engine section, the other four elements, or continuing refinement of forward work. Most of the hardware and systems that will fly on EM-1 are being built for the first time and the procedures to connect the five pieces of the Core Stage together will also be attempted for the first time.

Of the five elements, the most recent news had the Forward Skirt near completion of its individual work by the end of the month. Work to cover the liquid oxygen tank with its Thermal Protection System (TPS) foam was in final phases, with the liquid hydrogen tank to follow behind it. The engine section and intertank elements continue to be outfitted with propellant lines, pressure tanks, avionics boxes, wiring, and other equipment.

Once complete, the elements will be assembled vertically in two stacks before a horizontal join of the halves of the rocket kicks off final assembly.

In fact, reading the article’s detailed description of the testing and assembly of SLS’s core stage struck me as incredibly slow-paced, so slow paced that it actually filled me with a sense of ennui. In the time they seem to need to only do an equipment review, SpaceX appears to have upgraded and flown a new version of its Falcon 9 first stage, while also redesigning a new core stage for its Falcon Heavy.

Europa water plume detected in old Galileo data

8:22 am

Using old Galileo data and new techniques of analysis scientists have uncovered a water plume on Europa that the spacecraft flew through in 1997.

Over the course of 5 minutes, spikes the spacecraft recorded with its magnetic and plasma sensors reflected the alterations that a veil of ejected water, from one or many vents, could cause in a region matching the telescope observations, they report today in Nature Astronomy. This indicates that a region of the moon potentially 1000 kilometers long could host such activity, though it is impossible to say whether this is a single plume or many, like the complex system of fractures and vents seen on Enceladus. Indeed, on its own, this evidence was too weak to tie to erupting water in a 2001 study describing it, the authors add, but it fits well with the Hubble and modeled evidence.

As indicated by the quote above, the result has a lot of uncertainty.

1984 at the University of Michigan

1:03 pm

Fascist academia: The University of Michigan has been sued by a free speech organization for its 1984-like rules that threaten students with punishment, even re-education camps, if they dare express any opinion that might offend its organized thought police.

As the lawsuit says, the university has created an “elaborate investigatory and disciplinary apparatus to suppress and punish speech other students deem ‘demeaning,’ ‘bothersome,’ or ‘hurtful’.” Yes, really: The student disciplinary code defines “harassment” as any “unwanted negative attention perceived as intimidating, demeaning, or bothersome to an individual”

…The university has its version of the Stasi and Orwell’s Thought Police — a “Bias Response Team” that investigates supposed “bias” complaints from offended students — students who can file their complaints anonymously. So if you are accused of wrongdoing, you don’t even have a right to confront your accuser — just like the former citizens of East Germany where the Stasi had literally hundreds of thousands of informers who could be your next-door neighbor or even a member of your own family. Or in this case, a student down the hall or from one of your classes.

If you think this Star Chamber process is limited to verbal speech, think again. Just like the electronic surveillance in Oceania, the “Bias Incident Report Log” posted by Michigan on its website shows that the Bias Response Team may come after you for what you do and say in “On-line/Social Media” communications including texts, emails, and Twitter.

The log also shows that the campus secret police — sorry, the Bias Response Team — also goes after “Off Campus” speech. So students aren’t safe anywhere. Their First Amendment rights are severely restricted, no matter what they are doing or where they are.

So a student may literally receive a knock on his door “from a team of University officials threatening to refer the student to formal disciplinary authorities” for something some unknown, anonymous informant alleges that he said, something the informant doesn’t like, or doesn’t agree with, or is uncomfortable with. Unless, of course, as the complaint says, the student agrees to submit “to ‘restorative justice,’ ‘individual education,’ or ‘unconscious bias training’.”

In other words, the only way a student may be able to avoid formal charges against meritless claims is by agreeing to submit to the academic equivalent of a communist-style “re-education” camp or brainwashing about the latest liberal fad like “unconscious bias.”

Read it all. It is pretty horrible, and makes me wonder why the state government is providing any funds to this fascist-run university. Time to shut it down.

Chaos on Mars

11:56 am

chaos terrain

Cool image time! The image on the right, cropped and reduced in resolution to post here, shows an area on Mars that geologists have dubbed “Chaos Terrain.” If you click on the image you can see the full image, which also includes several canyons oriented in what seem to be random directions.

I first heard this geological term for regions on Mars shortly after the first orbital missions circling Mars began taking images back in the 1970s. It applied to places where the terrain was hummocky, a crazy collection of hills forming no pattern at all. Earth does not really have such terrain.

The close-up to the right also shows that at least one of these hills is fractured, made up of several large pieces that have separated over time.

This image was part of the May 2nd image release from the high resolution camera on Mars Reconnaissance Orbiter. What makes it interesting is its location on Mars. The image below shows that location, indicated by a white cross.

Dozens killed, including armed terrorists, in Gaza border violence

9:08 am

They also call this cutting off your nose to spite your face: Dozens have been killed today in riots along the Gaza-Israreli border as thousands of Gazan protesters attempted to invade Israel.

More than 35,000 protesters amassed at a dozen locations along the security fence, with many engaging in skirmishes that pushed the death toll Monday to the highest in Gaza since a 2014 cross-border standoff between the militant group Hamas and the Jewish state, according to the Associated Press.

Gaza health officials told the news agency that 41 people so far have been killed in Monday’s violence, and at least 772 have been wounded.

The relocation of the embassy from Tel Aviv, a key campaign promise of President Trump, has infuriated the Palestinians, who seek east Jerusalem as a future capital.

“Moments ago, an IDF patrol foiled a bomb-laying attack by a cell of three armed terrorists near Rafah, close to the border,” the Israeli military said Monday. “This is a particularly violent protest point. The troops responded with fire at the terrorists. The terrorists were killed.”

You want to live in peace? You show others that you mean it. You want others to see you as violent and a killer? You do things that prove it.

These demonstrations prove the latter. In the seventy years since Israel’s founding, that nation has shown, time after time, that it is more than willing to work with the Arabs, the Palestinians, the international community, anyone, in order to establish peaceful relations with its neighbors. Israel even unilaterally walked out of Gaza in order to show the world and the Palestinians that they are willing to allow an independent Palestinian state to exist side-by-side with Israel.

The Gazans here once again prove that they are unready to do so. They only hate, and want to kill, emotions that are hardly a good foundation for a reliable peace treaty.

Riots prompted by Hamas have left Gaza with fuel crisis

7:53 pm

This is called shooting oneself in the foot: The riots that the Hamas leadership of Gaza have been pushing this week have left the territory without cooking gas or diesel fuel, and no way to obtain more.

In Friday night’s attack, a large crowd broke into the Palestinian side of the Kerem Shalom crossing between Gaza and Israel, badly damaging a fuel and gas terminal and a conveyor belt for aggregate and animal feed.

Israel closed Kerem Shalom, saying it would take weeks or months to repair several million dollars in damages. It was not clear when the delivery of consumer goods by trucks would resume, said an army spokesman, Lt. Col. Jonathan Conricus, adding that six trucks with medical supplies entered Gaza on Sunday.

There has been widespread speculation about the motives for the vandalism, with Israel holding Gaza’s rulers from the Islamic militant Hamas group responsible. Friday’s attack was the second on Kerem Shalom in a week, raising questions about why Hamas did not try to protect a key installation.

They estimate that Gaza only has about 7 to 10 days of fuel remaining.

It is unclear if Hamas leaders prompted the riot that destroyed the depot, or if the rioters themselves went out of control. No matter. It illustrates a madness in Gaza that has existed since Israel unilaterally left, giving them control of their own territory so they could rule themselves.

Rather than demonstrate that they were ready for their own state, the residents of Gaza have since chosen a terrorist organization as their leaders, destroyed the profitable infrastructure and businesses that the Israelis left them, and instead devoted their efforts to building missiles and bombs to fling at Israel.

This new destruction is merely par for the course. The riots that I expect tomorrow, when many Gaza residents will try to breach the border, under pressure from or in support of the Hamas leadership, is only going to cause more harm to those residents, and accomplish nothing good.

The cave dwellers of China

7:40 pm

Even as China tries to make them move out, the ethnic Miao villagers that have built homes and lived inside a cave for the past century or so refuse to leave.

Why? This explains it:

A cottage industry has popped up in which the cave dwellers earn extra money by renting out rooms in their homes, which over time have clustered within Zhong cave, a limestone cavern big enough to hold four American football fields. The hangar-like cave is so large that their wooden or bamboo-made residences form a small, subterranean village built along its undulating walls.

…Officials say that residents have not taken care of the cave, leaving it unsuitable for inhabitation, and that the government should oversee the village as it is listed as a protected community by the Getu River Tourism Administration, a local agency. They have offered each resident 60,000 renminbi, or approximately $9,500, to leave.

Only five families have agreed to move. The remaining 18 families have held on stubbornly to their homes inside the cave. They say that the new homes are too small, that they fear losing access to their land, and that they alone, because of their historical connection to the cave, should have the right to independently control its small tourism economy.

The Chinese government is simply not offering them enough to leave. And should they leave, I would expect the villagers to come out on the raw end of the deal, while the cave itself, no longer protected by their presence and financial self-interest to preserve it, will also suffer.

Hat tip Willi Kusche.

ULA picks Aerojet Rocketdyne engine for Vulcan upper stage

9:35 am

Capitalism in space: ULA has chosen an Aerojet Rocketdyne engine to power the upper stage of its next generation rocket Vulcan.

The company has not yet made a decision on the engine for the first stage, where Blue Origin’s BE-4 still appears favored over Aerojet Rocketdyne’s AR-1 engine. This decision on the upper stage could partly be a political move, giving Aerojet the upper stage in order to make it easier to give the lower stage to Blue Origin.

ULA is forced to play politics here because politicians are involved. A number of power members of Congress want Aerojet Rocketdyne to get the business, and ULA risks offending these legislators should it abandon that company entirely.

Hiding messages using fonts

9:26 am

A new computer technique has been developed that uses subtle changes to a document’s fonts to encode secret messages and data.

Using Columbia University’s FontCode system, however, users can hide messages within unrelated text via virtually-invisible changes to the displayed letters.

Developed by a team led by associate professor of computer science Changxi Zheng, FontCode works with commonly-used fonts such as Times Roman, Helvetica, and Calibri, plus it’s compatible with most word processing programs. Additionally, the hidden messages are retained even when the document is printed on paper or converted to a different file type.

The video at the link explains very nicely how this works. The technology has some excellent potentially positive applications, such as providing a method of finding out if an original document has been modified. It also carries with it a great potential for misuse because of its ability to hide information unobtrusively in a written document.

NASA will fly a test drone on 2020 Mars rover mission

4:02 pm

NASA today announced that a test drone, dubbed Mars Helicopter, will be flown on the 2020 Mars rover mission.

Once the rover is on the planet’s surface, a suitable location will be found to deploy the helicopter down from the vehicle and place it onto the ground. The rover then will be driven away from the helicopter to a safe distance from which it will relay commands. After its batteries are charged and a myriad of tests are performed, controllers on Earth will command the Mars Helicopter to take its first autonomous flight into history.

“We don’t have a pilot and Earth will be several light minutes away, so there is no way to joystick this mission in real time,” said Aung. “Instead, we have an autonomous capability that will be able to receive and interpret commands from the ground, and then fly the mission on its own.”

The full 30-day flight test campaign will include up to five flights of incrementally farther flight distances, up to a few hundred meters, and longer durations as long as 90 seconds, over a period. On its first flight, the helicopter will make a short vertical climb to 10 feet (3 meters), where it will hover for about 30 seconds.

As a technology demonstration, the Mars Helicopter is considered a high-risk, high-reward project. If it does not work, the Mars 2020 mission will not be impacted. If it does work, helicopters may have a real future as low-flying scouts and aerial vehicles to access locations not reachable by ground travel.

The only word I can think of to express my thoughts on this is “Cool!”

SpaceX successfully launches in Block 5 Falcon 9

1:23 pm

Capitalism in space: SpaceX today successfully placed in orbit Bangladesh’s first communications satellite, successfully using its upgraded Block 5 version of the Falcon 9 rocket, its first stage designed to be reused a minimum of ten times.

They successfully recovered the first stage, and will now take it apart to confirm this new version worked as planned. If so, it will be put back together and returned to service.

The leaders in the 2018 launch standings:

14 China
9 SpaceX
5 Russia
5 ULA

The U.S. and China are once again tied at 14 for the nation lead. SpaceX’s launch rate is presently double what it achieved last year, when it launched the most rockets of any private company ever.

Did the Obama administration use the FBI to put a spy in the Trump campaign?

10:16 am

New evidence forced by Congress from the FBI now suggests that during the campaign the Obama administration used the FBI to insert a spy into the Trump campaign.

The details can be found here, including this quote:

The bureau already has some explaining to do. Thanks to the Washington Post’s unnamed law-enforcement leakers, we know Mr. Nunes’s request deals with a “top secret intelligence source” of the FBI and CIA, who is a U.S. citizen and who was involved in the Russia collusion probe. When government agencies refer to sources, they mean people who appear to be average citizens but use their profession or contacts to spy for the agency. Ergo, we might take this to mean that the FBI secretly had a person on the payroll who used his or her non-FBI credentials to interact in some capacity with the Trump campaign.

This would amount to spying, and it is hugely disconcerting. It would also be a major escalation from the electronic surveillance we already knew about, which was bad enough. Obama political appointees rampantly “unmasked” Trump campaign officials to monitor their conversations, while the FBI played dirty with its surveillance warrant against Carter Page, failing to tell the Foreign Intelligence Surveillance Court that its supporting information came from the Hillary Clinton campaign. Now we find it may have also been rolling out human intelligence, John Le Carré style, to infiltrate the Trump campaign.

If this is true, this abuse of power here by the Obama administration, during a campaign, is far worse that anything anyone has accused Trump of doing. More important, we have zero evidence against Trump, but now ample evidence against Obama and the Democrats. Just as Obama weaponized the IRS illegally to attack conservatives, it now appears he used the FBI and the Justice Department to illegally spy on the Republican campaign for President.

The Middle East following Trump’s rejection of Iran deal

9:54 am

Many pundits had predicted that Donald Trump as president would lead to war with North Korea.

They were wrong. Completely, utterly, and foolishly. Instead, Trump’s hardline approach finally forced North Korea’s allies to force that nation to come to the negotiating table. For the first time in decades it appears we are going to see some substantive and positive changes in North Korea’s relations with the world.

This same pundit class, all operatives of the Democratic Party, have for the last few days been screaming that Trump’s exit from the Iran nuclear deal would also lead to war. Will these predictions be right this time? At this moment it is hard to say. Almost immediately after Trump’s announcement Iran and Israel exchanged missile fire. Overall, however, that exchange has turned out badly for Iran, the world’s biggest financier of terrorism and the instigator of most of the problems that presently exist in the Middle East.

First, it appears that militarily Iran did badly in the missile exchange, with Israel doing their capabilities in Syria serious harm. Second, Iran apparently did not tell anyone in Syria it was going to do use that country as a military launch site, and this is already causing them problems with their allies. For example, Russia announced today that it will not deliver new missiles to Syria, despite an earlier promise to do so.

Finally, a host of Arab Middle East countries have not only celebrated Trump’s actions, it has prompted some to reveal support for Israel, something that would have seemed impossible only two years ago.

It remains unclear if Trump’s actions will have the same positive effect on Iran as his actions did on North Korea. The two situations are not identical. Iran’s leaders have more flexibility and options that North Korea’s. Still, what Trump has accomplished is to get some important Arab nations to move to our side against Iran, and in doing so to increasingly ally themselves with Israel as well. This cannot be a bad thing.

Meanwhile, the anti-Semitic leader of Hamas announced yesterday that the protests next week in Gaza will be “decisive” and that many will die. Whether this really happens, it is apparent that such protests are not garnering Hamas the same worldwide support they once did. The same Middle East countries that have celebrated Trump’s actions have also made it clear they no longer support the terrorist tactics of the leaders in both the West Bank and Gaza. These Arab nations have quietly made it clear that they actually back Israel now.

Trump’s actions in the Middle East appear to have shifted the balance of power, and that shift has been in favor of Israel, the only democratically-elected nation in the area. This cannot be a bad thing.

People object to Google’s robot call technology sounding just like a human

9:18 am

In creating its new Google assistant, called Duplex, and designing it to be able to make phone calls to schedule appointments, the company made it indistinguishable from a human and successfully hid the fact that it was a robot.

The company was then surprised that many were horrified by this and objected.

The demonstration of the technology at the conference was both impressive and startling. The first example showed Duplex calling a hair salon and scheduling an appointment. The second example involved an even more complex conversation, with the system calling a restaurant to try to make a reservation. In the course of the conversation the system is told it wouldn’t need a reservation for that many people on that particular day. Understanding this, Duplex thanks the person on the other end and hangs up.

These examples of a human-sounding AI interacting with a real person are undeniably impressive, but the technology’s ability to so blatantly fool another human being into thinking it is real has left many unnerved. From suggestions Google had failed at ethical and creative AI design to more explicit accusations that the company was ethically lost, rudderless and outright deceptive, it seems something had gone drastically wrong.

You can watch the demonstration at the link. The robocall technology is quite amazing, and it is also incredibly dishonest and morally bankrupt. Google makes no effort to identify its robot to the listener, and is actually proud that it successfully fools them into thinking they are talking to a human.

The article notes that the company has gotten a lot of negative response to this, and has since said it will always make full disclosure in the future. I have my doubts. I also expect that politicians and survey companies will soon take advantage of this as well. I now routinely hang up on surveys that use robots. To discover that they can fool us makes me want to hang up on all surveys, in all cases.

Cracks in pedestrian bridge possible root of failure

2:42 pm

Cracks found in a Florida pedestrian bridge prior to its collapse, killing six, might have indicated the upcoming failure.

A key concrete support truss in the doomed Florida International University pedestrian bridge developed worrisome cracks 10 days before the structure was lifted into place over the Tamiami Trail, photographs and an internal email unintentionally released by the school show.

The documents, released in response to public records requests from the Miami Herald, show that FIU’s construction and engineering team discovered potentially problematic cracks in the bridge earlier than officials have previously acknowledged.

Because of the ongoing investigation we do not yet how the engineering company building the bridge responded to the cracks. They might have analyzed them and dismissed them. Or the might have ignored them entirely.

Most scientific studies cannot be reproduced

12:13 pm

A new report looking at a number of important research studies has found that almost all could not be reproduced, and that the research was often fraught with fraud and “political groupthink.”

For this study, researchers tried to reproduce the results of “53 landmark studies in oncology and hematology.” Researchers were only able to replicate the results of six studies. “People have found similar results in psychology and economics. Different fields are affected different amounts,” Randall told The College Fix. “As a rule of thumb, fields that use statistics intensively are more likely to have troubles than fields that don’t.”

The report hypothesized that there are a number of different reasons for irreproducibility that include such things as “flawed statistics, faulty data, deliberate exclusion of data, and political groupthink,” among other reasons. “Actual fraud on the part of researchers appears to be a growing problem,” the report also states.

The report also singled out the field of climate science as having significant problems along these same lines, especially in areas of its statistical research.

Mars Odyssey looks down at Curiosity

10:39 am

Gale Crater

The Mars Odyssey team today released an image the spacecraft took of Gale Crater on January 16, 2018. This image, reduced in resolution, is posted on the right and captures the entire region that the rover Curiosity has been traversing for the past six years. If you click on the image you can view the full resolution original.

I have placed Curiosity’s full route since its landing on this image so that we can see where the rover has been. The actual peak of Mount Sharp is a considerable distance to the south and is not visible in this image. (For the full context of the crater and Curiosity’s travels see my March 2016 post, Pinpointing Curiosity’s location in Gale Crater)

The river-like flow feature cutting through the north rim is called Peace Vallis. Scientists think this was formed by water flowing into the crater when the climate of Mars was wetter and there was a lake inside the crater floor.

You can get another perspective of this same view by looking at the panorama looking north that Curiosity took once it climbed up onto Vera Rubin Ridge.

I have said this before, but this Mars Odyssey image once again illustrates how little of Mars we have so far seen. Curiosity has barely begun its climb into the foothills of Mount Sharp. The mile-high mountains that form the rim of Gale Crater are far away, and will not be walked for probably generations. I do not expect any space probe or explorer to enter Peace Vallis for at least a hundred years, since there are so many other places on Mars to visit and Gale Crater has already gotten its first reconnaissance by Curiosity.

The image also gives as a view of Curiosity’s future travels. Based on this October 3, 2016 press release, Curiosity will eventually head into the mouth of the large canyon directly to the south of its present position. Whether the mission will continue up this canyon wash, using it as the route up Mount Sharp, will depend on many things, including the roughness of the terrain in that canyon and the simple question of whether the rover will be able to operate that long.

If it does, the views then from inside that canyon should be quite breathtaking.
