Russians routinely disrupt GPS data in sensitive areas

March 27, 2019 12:14 pm Robert Zimmerman

According to one report, in the past three years the Russians have routinely and successfully fed fake GPS data to units at locations the Russians consider sensitive or of high priority.

The report — published by the Center for Advanced Defense (C4ADS), a nonprofit intelligence firm focused on worldwide security issues — found that at least 9,883 instances of spoofing occurred near sensitive areas in Russia and Crimea and during times when high-ranking officials, such as President Vladamir Putin, were present. In addition, the data showed that spoofing regularly occurred near Khmeimim Airbase in Syria during Russian operations there.

The findings underscore the dangers of relying on global positioning data, such as that provided by the global positioning system and similar technology across the globe, because the service can be disrupted or co-opted to deliver false data, says one author of the C4ADS report, who asked not to be named because of the sensitivity of the topic.

The story also described one case where researchers at the University of Texas in Austin:

were able to build a device for less than $1,000 to spoof the position of a ship and cause it to change course. “The ship actually turned, and we could all feel it, but the chart display and the crew saw only a straight line,” said Todd Humphreys, assistant professor of the department of aerospace engineering and engineering mechanics, at the time.

None of this should surprise anyone. It does however underline the need for there to be alternative navigational systems available. Ship’s crews should have a sextant available and should know how to use it. Missiles and airplanes similarly should have a backup system to check their GPS against.

And hikers and drivers should never totally rely on their GPS. Use it as a map, for guidance, but always verify its suggestions with common sense.

The National Space Council’s full recommendations

March 27, 2019 9:31 am Robert Zimmerman

Yesterday’s meeting of the National Space Council resulted in a number of recommendations beyond vice-president Mike Pence’s announcement that the Trump administration is quite willing to dump SLS if it doesn’t get its act together.

First, see this statement by NASA administrator Jim Bridenstine. He outlines the tasks that NASA has now been given, including getting astronauts on the Moon by 2024. Those tasks also require NASA to “[s]tay on schedule for flying Exploration Mission-1 with Orion on the Space Launch System (SLS) rocket next year, and for sending the first crewed mission to the lunar vicinity by 2022.”

This article at SpacePolicyOnline outlines those tasks in more detail, stating that:

NASA will create a Moon-to-Mars Mission Directorate and make all necessary efforts to achieve Exploration Mission-1 no later than 2020 and Exploration Mission-2 no later than 2022. [emphasis mine]

These announcements inadvertently reveal two facts. First, the establishment of a new directorate at NASA is Bridenstine’s attempt to shake up and take control of NASA’s bureaucracy. This will allow him to put people in place that support his agenda.

Will this work? I doubt it. I have watched NASA administrators do this time after time in the past twenty years, with nothing really changing. In a sense, it is really nothing more than rearranging the deck chairs on the Titanic.

Second, they are admitting here (as indicated by the highlighted words) that the first SLS unmanned launch will not happen in June 2020. They have reviewed everything and realized the fastest way to get this launch off is to allow SLS to launch it, but they have also realized that the June date can’t be met. This announcement gives NASA and Boeing an extra six months, to the end of 2020, to get the mission off the ground.

The recommendations also included the release of major suggested changes to streamline how both the State Department and the FAA regulate commercial space. Neither appear to streamline things much. For example, the FAA’s new rule [pdf] on federal commercial space transportation requirements is only 580 pages long. My eyes glazed over as soon as I started reading it. Similarly, the new State Department procedures appear as complex. I haven’t digested either yet, so my pessimism might be unfounded. We shall see.

All in all, the significance of these policy announcements is not so much in the details, all of which illustrate the continuing incompetence and failures of the federal space bureaucracy. What these announcements instead tell us is that the Trump administration is finally attempting the first baby steps for gaining some measure of control over that federal space bureaucracy. It is telling that bureaucracy that it had finally has to do something, or face the consequences.

Whether the administration’s efforts will succeed however remains very questionable. Many in that bureaucracy and in Congress will oppose this effort. They like things as they are, where billions get distributed throughout the country to their friends, and no one is ever required to accomplish anything. And they have managed for the past twenty years to maintain this status quo. It will not be easy to force a change now.

India claims it has successfully destroyed a satellite using an anti-sat missile

March 27, 2019 8:56 am Robert Zimmerman

The new colonial movement: In a speech to his nation today, India’s Prime Minister Narendra Modi announced that they have successfully completed their first anti-sat test, using a missile to destroy a satellite in low Earth orbit.

The Indian ASAT test is believed to have destroyed either the Microsat-R or the Microsat-TD satellite, likelier the former according to some sources. They were both built by the Defence Research and Development Organisation (DRDO). ISRO launched the Microsat-R on January 24 this year and the Microsat-TD a year before that.

Prime Minister Modi declared the test, codenamed Mission Shakti, a success and claimed that an ASAT missile had destroyed the satellite in its low-Earth orbit.

The missile in question is described as a kinetic kill vehicle, which means it does not carry any explosives or other devices. Instead, its ‘kill’ capability arises simply from the fact that it smashes into the target satellite and shatters it using its kinetic energy.

At this altitude, about 300 km, experts said that debris from the collision would fall back to Earth, burning up in the atmosphere in a matter of weeks instead of posing a threat to other satellites. As a result, Mission Shakti is called a controlled ASAT test.

What this anti-sat test really demonstrates is India’s ability to to hit a very tiny target that is moving more than 17,000 miles per hour with a missile shot from Earth, which proves they can hit any target on Earth, with great accuracy. And it thus a blunt message to both Pakistan and China. Don’t attack us, because if you do, we have the capability to do you great harm.

Children benefit more when parents read to them from printed books

March 27, 2019 8:36 am Robert Zimmerman

A new study has found that parent-child interactions are more enhanced when parents read to them using printed books rather than ebooks.

The results were starkly clear, with verbal interactions between parent and child decreasing when using either form of e-book. The study revealed e-books and enhanced e-books altered both the activity of the parent and the child’s response to the experience. Parents using enhanced e-books, for example, asked fewer prompting questions to a child while reading, and what conversation there was tended to more frequently be about the device and the technology, instead of the story and characters.

“Parents strengthen their children’s ability to acquire knowledge by relating new content to their children’s lived experiences,” says lead author in the study Tiffany Munzer. “Research tells us that parent-led conversations are especially important for toddlers because they learn and retain new information better from in-person interactions than from digital media.”

The study is not an outright condemnation of ebooks. It is instead a first guidepost for reworking the electronic medium to make it function better, in all cases.

OneSpace orbital launch fails

March 27, 2019 8:31 am Robert Zimmerman

Capitalism in space? The first orbital launch attempt by China’s smallsat company OneSpace failed today.

No information about the cause of the failure or what happened has been released as yet.

I’m going to say this again: While OneSpace is financed through private capital, like a private company, it is also supervised closely by the Chinese government. It is hardly a private company as we in the West would define it.

Pence reiterates Trump administration’s willingness to abandon SLS

March 26, 2019 1:15 pm Robert Zimmerman

Turf war! At today’s National Space Council meeting, vice-president Mike Pence reiterated the Trump administration’s willingness to replace SLS with commercial rockets, if that is what it will take to get Americans back to the Moon by 2024.

Pence said the schedule for completing SLS must be accelerated, but also opened the door to using rockets built by a commercial spaceflight company for the lunar mission. “We’re not committed to any one contractor. If our current contractors can’t meet this objective, then we’ll find ones that will,” he said. “And if commercial rockets are the only way to get American astronauts to the moon in the next five years, then commercial rockets it will be.”

It is very clear now that the Trump administration is beginning the political war necessary for shutting down the SLS boondoggle, something that cannot happen easily considering how its large workforce is scattered in so many states and congressional districts. To make it happen, they need to publicly illustrate its failure, repeatedly, but do so in a manner that does not overly antagonize SLS’s supporters. This is why both Pence and NASA administrator Jim Bridenstine have been careful to express support for SLS, even as they hint at its replacement.

The battle is joined, however, and that could be a very good thing for the American space industry, in the coming years.

Strange craters in the Martian northern lowlands

March 26, 2019 12:58 pm Robert Zimmerman

Click for full image.

Cool image time! The image on the right, cropped and rotated to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and released in the monthly image dump provided by the science team. The release had no caption. It merely described this as a “Layered mound in crater.”

That is certainly what is is. However, layering suggests a regionwide process. The crater to the immediate northeast (the rim of which can be seen in the upper corner of this image), does not have the same kind of layering. (Be sure to click on the image to see that other crater.) Its crater floor is instead a blob of chaotic knobs, with the only layering scattered in spots along its north interior rim.

That the layering of both craters favors the north suggests a relationship, but what that is is beyond me. Prevailing winds? Maybe, but I don’t have the knowledge to explain how that process would work.

It is not even certain that these two craters were formed by impact. They are located in the northern lowlands where an intermittent ocean is believed to have once existed, and thus might be remnants of that ocean’s floor. That they both have a muddy appearance reinforces this hypothesis, but once again, I would not bet much money on this theory. The features here could also be expressing the effect of an impact on a muddy seafloor.

In either case the craters imply that the ocean that might have once been here existed a long enough time ago for these craters to form (either by impact or some other process) and then evolve. This has been a relatively dry place for a very long time.

OneSpace to attempt first orbital launch this week

March 26, 2019 9:20 am Robert Zimmerman

OneSpace, one of a bunch of companies in China attempting to launch smallsats, is expected to attempt its first orbital launch this week.

The article gives a nice overview of the present competition in China between several of these smallsat private companies, dubbed OneSpace, LandSpace, ISpace, and LinkSpace. All are funded through private investment capital, so all claim to be a private companies. However, nothing done in space in China is done without the approval and direction of the government. They might be designed as private companies, but they are also designed expressly to serve the needs of the Chinese government. That their company names are all so similar only strengthens this conclusion.

Key House Democrat announces opposition to Trump’s Space Force proposal

March 26, 2019 9:10 am Robert Zimmerman

Adam Smith (D-Washington), the House Democrat who now heads the committee that approves military space funding, has announced his opposition to Trump’s Space Force proposal.

He revealed two objections. One, he claimed the proposal was top heavy in management, with its leadership delegated to one civilian and two generals. The second complaint I think is more pertinent.

The Trump proposal includes language about the Space Force’s civilian workforce that the Democrats just can’t stomach. In his statement, Smith says that “a large part of the proposal is an attack on the rights of DoD civilian employees. It asks for broad authority to waive long-standing and effective elements of civil service rules, pay rates, merit-based hiring, and senior civilian management practices.”

As usual, the Democrats are more interested in acting as union reps for the government workforce than serving the needs of the country. Trump’s proposal, as put forth, might not make sense, but Smith is clearly not interested in fixing it. Instead, he wants shape this new bureaucracy so that it provides him and DC with more funding and power. The country can go to hell.

Russia cuts Proton price to match SpaceX

March 26, 2019 9:00 am Robert Zimmerman

Capitalism in space: Dmitry Rogozin, the head of Roscosmos, yesterday said that Russia will cut costs so that the price they charge for a Proton launch will match SpaceX.

Russia is struggling to regain its Proton customer base after the launch failures of the past few years. I don’t think matching SpaceX’s prices will do it. Right now satellite companies view them as offering a less reliable product, and until they can prove this impression false they need to offer their rocket for even less that SpaceX.

This is in fact what SpaceX did at the beginning. Its rockets were untested and thus risky to use. To compensate they offered a cheaper way to space. Now Russia has to do the same, or the business will continue to go to others. I wonder if Rogozin understands this.

Update of Starhopper testing in Texas

March 26, 2019 8:43 am Robert Zimmerman

Link here. Nothing spectacular yet, just steady and relatively quick developments.

I did find one aspect of these events a little disturbing:

In quick order, residents of Boca Chica Village were notified via mail of imminent tests and road closures that would occur as early as this week, the week of 18 March.

The notice to residents revealed that a security checkpoint would be set up on the road leading to Boca Chica Village and that residents would have to show proof of residence in order to gain access to their homes; any passengers in those vehicles would also have to show proof of residence.

This indicates that no guests will be allowed past the security checkpoint during the coming flight test operations of Starhopper.

A hard checkpoint beyond which no access to Boca Chica Beach will be granted will be further down the road.

By what right do the authorities have the power to prevent American citizens from bringing guests to their homes? None. If I lived in this development I would fight this, hard.

U.S. recognizes Israeli sovereignty of Golan Heights

March 25, 2019 4:50 pm Robert Zimmerman

The United States today officially recognized the Israeli claim of sovereignty over the Golan Heights.

President Trump on Monday formally recognized the Golan Heights as Israeli territory, giving Prime Minister Benjamin Netanyahu a much-needed boost as he raced home to respond to a rocket attack that struck near Tel Aviv, wounding seven.

Mr. Trump’s proclamation reversed about a half-century of U.S. policy, which viewed the Golan Heights as Syrian territory occupied by Israel. “This was a long time in the making, it should have taken place many decades ago,” Mr. Trump said as he signed the papers inside the White House.

The rocket attack came from Gaza, causing Netanyahu to cut short his U.S. trip to deal with it.

Remember Gaza? That was the territory that Israel once controlled, and unilaterally left in order to give the Palestinians their own sovereign state. They have since used that sovereignty to elect terrorists as their leaders, and to lob bombs at innocent Israelis.

European Court upholds conviction for condemning Mohammad’s child marriage

March 25, 2019 3:35 pm Robert Zimmerman

Fascist Europe: The European Court today upheld the Austrian conviction and punishment of a woman merely because she gave a talk where she described and then condemned Mohammad’s child marriage to a six-year-old, that he consummated with a rape when the child was nine.

Sabaditsch-Wolff, a diplomat’s daughter who has lived and worked in the Middle East, was censured for having spoken at a meeting organized by the right-wing Austrian Freedom Party 10 years ago in Vienna. Her intention was to speak about the treatment of women and the practice of jihad (“Holy War”) in countries such as Iran and Libya, on the basis of her own experience.

During her speech aimed at an audience of about 30 people, she spoke freely about the prophet Muhammad and his relationship with Aisha, whom he saw and desired when she was six years old. He married her on the spot, and the union was consummated when she was nine. He “liked to do it with children,” she said, adding that she had argued with her sister about the words she would use to describe the facts.

She insisted on being straightforward: “A 56-year-old and a six-year-old? What do we call it, if it is not pedophilia?”

A journalist present at the meeting taped her words. His editor-in-chief went on to turn them over to the police, and Sabaditsch-Wolff was indicted for inciting hatred toward Muslims and for having disparaged their prophet as unworthy of veneration.

She was not found guilty of the first violation. But she was condemned for the “disparagement” in 2011 to a 480-euro fine (about 550 U.S. dollars) or up to 60 days imprisonment.

The court has essentially endorsed the heckler’s veto, though we all know that if a Christian tried to do the same they would be denied. What will now happen is that the European Union will team up with vast numbers of new Muslim immigrants it forced its member nations to accept in the past decade to impose sharia on Europe.

College political course chooses authors by race

March 25, 2019 3:07 pm Robert Zimmerman

Bigoted academia: A college course at the University of Colorado-Denver that is falsely dubbed “American Political Thought” specifically excludes any white authors from its reading list.

The syllabus fails to mention any of the major figures in America’s founding, including the Founding Fathers. When challenged by The College Fix on the lack of these voices in the syllabus given the title of the course, [Professor Chad] Shomura argued that he aims to encourage students to expand their perception of which thinkers are included in mainstream American thought. Shomura even admitted that past students have criticized the disconnect between the title of the course and the assigned texts.

Even if the course was titled “Fringe Figures in American Political Thought” it would still be bigoted. The criteria used to pick the reading material is not based on content but purely on race.

There was a time when everyone would have seen this professor for the bigot that he is. Now, we make excuses.

Does the Mueller report suggest there is hope?

March 25, 2019 1:28 pm Robert Zimmerman

I have come to three somewhat contradictory conclusions in thinking this weekend about the unexpectedly reasonable conclusions announced in the final Mueller report, stating that, despite two years of intense investigation which at times bordered on a witch hunt, there was no collusion between Trump and the Russians to win the election.

1. Robert Mueller is a hack who works hard for the liberal Washington swamp, doing their bidding whenever he can. The summary letter of his report by Attorney General William Barr inadvertently reveals this.

In the first paragraph of Barr’s letter he describes Mueller’s report has entitled “Report on the Investigation into Russian Interference in the 2016 Presidential Election.” This would imply that Mueller’s goal was to investigate all possible aspects of Russian interference, including collusion that might have also taken place in the Clinton campaign.

However, in the very next paragraph Barr states,

Rogozin: Investigation into Soyuz sabotage to continue on ISS

March 25, 2019 9:22 am Robert Zimmerman

In his remarks to journalists today Roscosmos head Dmitry Rogozin also said that the Russian investigation into the hole that was drilled in a Soyuz capsule last year is not over, and that they plan to do further “experiments” on ISS.

“The samples collected on the ISS are insufficient for final conclusions. Apparently, additional experiments in orbit will be required,” Rogozin said.

What those “additional experiments in orbit” will be was not explained. I suspect he is referring to the security cameras the Russians are installing on their part of ISS, with the hope of catching the saboteur in the act.

What I think is going on here is that they have not been able to uncover who did this on the ground, and are now trying to imply it might have been sabotage by a U.S. astronaut. Rogozin can’t say this outright, because he wants to keep good relations with the U.S. in the partnership on ISS. He can hint at it, however, and let his own press run with it.

Russia offers to take over ISS if US exits

March 25, 2019 8:59 am Robert Zimmerman

How kind of them! Dmitry Rogozin, the head of Roscosmos, told journalists today that Russia has formulated a proposal to take over ISS operations completely should the U.S. withdraw from the station.

“This is Roscosmos’ proposal. We believe that we can keep the station in case the Americans decide to withdraw from this project, through other countries and partners. We have technological and technical capabilities to keep the station on the orbit and fully provide both electric energy and water there,” Rogozin said.

Roscosmos’ director general explained that the Russian section may add new modules on the basis of the Science-Power Module (SPM), the first version of which will be launched to the station in 2022. “Here the Russian Federation has a unique opportunity. We can duplicate the SPM. Its design makes it possible to turn into home for other states – there can be the SPM-2, SPM-3, SPM-4, they may grow further, extending the international part of the station. We formulated this proposal, and we suggest our new partners doing it,” Rogozin said. [emphasis mine]

The highlighted text reveals Russia’s real goal. They take over station operations, and then sell to other nations modules for the station. Does the UAE want its own space station manned program? Buy a Russian-built module of your own, get it attached to ISS, and “Voila!” you have a very sophisticated and relatively permanent in-space facility all your own. And Russia will provide you the manned ferrying services!

This idea makes great sense. The Russians could even do it should the U.S. stick with ISS. It allows them to offer something far superior to the private, small, and short-lived separate station modules that a variety of private American companies are developing and offering for purchase or rent.

Of course, NASA could do the same, by allowing our private companies to attach modules of their own to ISS, for their own purposes. Historically, however, NASA’s management has been hostile to private enterprise, and in the past has frequently acted to oppose independent commercial activities on ISS. For example, when Russians wanted to fly Dennis Tito to ISS NASA strongly opposed this, and tried to stop it.

NASA has been changing in the past decades, however, so it could be that if the Russians push this hard, the competition could help the factions in NASA who are favor of private and free competition gain control of station management.

Electron launch scrubbed, rescheduled for March 26

March 25, 2019 12:19 am Robert Zimmerman

Capitalism in space: Rocket Lab’s launch today of a DARPA satellite was scrubbed when a video transmitter did not work as expected.

“The team has identified a video transmitter 13dB down with low performance,” Rocket Lab tweeted. “It’s not an issue for flight, but we want to understand why, so we’re waiving off for the day.”

Peter Beck, Rocket Lab’s founder and CEO, added that the rocket was “technically good to fly, as we have redundant links, but we don’t know why the performance dropped and that makes me uncomfortable.”

In an update a few hours later, Rocket Lab said crews aim to replace the suspect video transmitter in time for a second launch attempt Tuesday (U.S. time). The four-hour launch window Tuesday will open at 6:30 p.m. EDT (2230 GMT).

Rocket Lab had hoped to move to monthly launches beginning in February. While they will probably do so before the year is out, it seems it might take most of the year to get to that pace.

Swedish Facebook suspends journalist for defending freedom of speech

March 24, 2019 5:12 pm Robert Zimmerman

They’re coming for you next: An independent journalist in Sweden says that she was suspended from Swedish Facebook for seven days for posting an essay supporting British reporter Tommy Robinson and the concept of true freedom of speech, where you defend all opinions, even those you oppose.

Independent journalist and freedom fighter Katerina Janouch wrote a short introduction for an article in her own online magazine “Katerina Magasin.” The article, written by another Swedish writer – Madeleine Rönnqvist Lilja — is about the British freedom fighter Tommy Robinson. In her text, Katerina wrote: “Defending freedom of expression when you agree is a breeze, but if we are to have any freedom of speech worth mentioning, it must also be defended when it is challenged and not all agree.” She then pointed out that it “may be your turn next”.

And Swedish Facebook took Katerina at her word and suspended her.

It would not surprise me if this claim is 100% true. However, the article does not provide detailed information about what Swedish Facebook claimed was the reason, if any, for the suspension, and the source article that does give those details is in Swedish. It is therefore possible that Facebook had some other reason for its actions. I just can’t confirm that.

I must emphasize however that I am trying to be unreasonably fair here. The behavior of large tech companies like Facebook, Google, Twitter, etc. has been routinely leftist and increasingly hostile to opposing opinions. Moreover, this is Swedish Facebook, where I expect the political culture is even more leftist and intolerant of opposing views. I would expect them to try an shut down any postings that express strong reservations about Islam, because the left for some reason has apparently decided that Muslims are a protected and oppressed minority that must never be challenged.

For those who are unfamiliar with Tommy Robinson, he is an activist and online writer who has been imprisoned and harassed by British authorities because he has been uncompromising in his reporting of radical Islam.

Mueller submits report, ends investigation

March 22, 2019 3:42 pm Robert Zimmerman

Special Council Robert Mueller today submitted his report to his new boss Attorney General Bill Barr at the Department of Justice, officially ending his two year long investigation that was supposedly aimed at proving collusion between Donald Trump and the Russian government in order to get him elected.

In those two years, Mueller made a few indictments, none of which had anything to do with Trump-Russian collusion. Most were process crimes, created during the investigation against individuals for either not answering questions perfectly or because Mueller went on a fishing expedition until he found something. None would have happened had this faux investigation had not been instigated.

Moreover, according to the news story at the link, Mueller is “not recommending any further indictments” with this submission.

Or to put it more bluntly, this was all a sham, aimed at deposing the legally elected president of the United States.

Meanwhile, evidence of real collusion, involving Obama and Hillary Clinton and the Russians, was ignored, and in fact the FBI took hostile actions against those involved in revealing it.

The pro-Iran and anti-Israel Democratic Party

March 22, 2019 2:25 pm Robert Zimmerman

Two stories in the past few days illustrate once again the growing fascist and anti-democratic trends within the modern Democratic Party, trends that every registered Democrat should look at with horror.

First there was condemnation by liberal activist groups like MoveOn and Code Pink of the American Israel Public Affairs Committee (AIPAC). Both also demanded that all Democratic presidential candidate boycott AIPAC’s annual conference. To quote MoveOn’s petition:

“It’s no secret that that AIPAC has worked to hinder diplomatic efforts like the Iran deal, is undermining Palestinian self-determination, and inviting figures actively involved in human rights violations to its stage,” Iram Ali, campaign director at MoveOn Political Action, said in a statement provided first to Politico. Ali said the move should “give a clear insight to 2020 candidates on where their base stands instead of prioritizing lobbying groups and policy people who rarely step outside of D.C.”

None of these claims are true. What AIPAC has done for decades is to support the right of Israel to exist, to oppose Islamic terrorism and the wholesale slaughter of Jews, and encourage the U.S. to work with the only viable democracy in the Middle East, for both Jews and Muslims.

These liberal demands were then followed by the immediate decision by all but one Democratic presidential candidate to skip the conference. What makes this significant is that many of these same Democrats have repeatedly spoken there in the past, and in doing so had expressed positive opinions about the organization.

Now however the Democratic Party increasingly sees Israel and its Jewish population as evil, and instead wish to ally themselves with the Islamic movement, a position that follows the lead of their younger anti-Semitic lawmakers like Ilhan Omar (D-Minnesota).

The party’s desire to link itself to radical Islam is demonstrated by the second story today, in which five Democratic presidential candidates announced their endorsement of Iran and the very bad Obama nuclear deal that the U.S. should never have agreed to and that President Trump wisely terminated last year.

Sens. Bernie Sanders (I-Vt.), Elizabeth Warren (D-Mass.), and Kamala Harris (D-Calif.) declared they’d rejoin the Iran deal if Iran abides by it and so did two less-known candidates: Mayor of Miramar, Florida, Wayne Messam and writer and charity activist Marianne Williamson, reported Al-Monitor on March 19.

Note that there is ample evidence, outlined in great detail at the link, that Iran never abided by the treaty, before or after its signing.

Not all the Democratic candidates made this endorsement, but the trend is clear, nonetheless. The Democratic Party now increasingly prefers to ally itself with nations whose leaders routinely chant “Death to America!” and call for the annihilation of Israel.

And this trend makes sense, considering that party’s willingness in the last few years to abandon or even reject the Bill of Rights, preferring to use force and the power of government to impose their will on everyone. For such a party, being fellow-travelers with dictators and tyrants is not difficult.

If you are an ordinary registered Democrat, you need to reassess your loyalty to that party. It is not the political organization you probably think it is.

Jezero Crater: The landing site for the Mars 2020 rover

March 22, 2019 12:21 pm Robert Zimmerman

Jezero Crater delta

At this week’s 50th Lunar and Planetary Science Conference in Texas, there were many papers detailing the geological, topographical, chemical, meteorology and biological circumstances at the landing sites for the 2020 Martian rovers, Jezero Crater for the U.S.’s Mars 2020 and Oxia Planum for Europe’s Rosalind Franklin.

Most of these papers are a bit too esoteric for the general public (though if you like to delve into this stuff like I do, go to the conference program and search for “Jezero” and “Oxia” and you can delve to your heart’s content).

Oxia Planum drainages

These papers do make it possible to understand why each site was chosen. I have already done this analysis for Rosalind Franklin, which you can read here and here. Oxia Planum is in the transition between the southern highlands and the northern lowlands (where an intermittent ocean might have once existed). Here can be found many shoreline features. In fact, one of the papers at this week’s conference mapped [pdf] the drainage patterns surrounding the landing ellipse, including the water catchment areas, as shown by the figure from that paper on the right.

With this post I want to focus on Jezero Crater, the Mars 2020 landing site. The image above shows the crater’s most interesting feature, an impressive delta of material that apparently flowed out of the break in the western wall of the crater.

This image however does not tell us much about where exactly the rover will land, or go. To do that, we must zoom out a bit.

Arianespace’s Vega rocket launches Italian earth observation satellite

March 22, 2019 12:09 am Robert Zimmerman

Capitalism in space: Arianespace today successfully used its Vega rocket to place an Italian earth observation satellite into orbit.

The leaders in the 2019 launch race:

3 SpaceX
3 China
3 Europe (Arianespace)
2 Russia
2 ULA

The U.S. still leads in the national rankings 5 to 3 over China and Europe.

The changing surface of Comet 67P/C-G

Changes on Comet 67P/C-G after outburst

More results from this week’s 50th Lunar and Planetary Science Conference in Texas! Two presentations today focused on showing the dramatic changes on the surface of Comet 67P/C-G that were documented by Rosetta. The first focused on the changes produced after massive outbursts during the comet’s closest approach to the Sun. The second documented several more evolutionary changes that changed more slowly.

The image to the right comes from the first paper, and shows the changes that took place on the surface following one massive outburst, with the numbers in red indicating unchanged features between the two photographs.

It appears an entire cliff section has disappeared, replaced by a single large giant boulder. Interestingly there is no obvious vent opening for the outburst. Instead, it appears that the eruption occurred below ground, and merely blasted part of the surface into space. As noted in the paper:

We report here on a third cliff collapse that occurred in the southern hemisphere in the Sobek region [7], which corresponds to the neck region in the 67P’s southern hemisphere. Due to the close alignment of the 67P’s
southern summer solstice with perihelion passage, the southern hemisphere is subjected to higher solar input, resulting in higher levels of activity and more intensive erosion. The location of the collapsing cliff in Sobek is consistent with the inferred source region of one of the strong outbursts [previously reported].

The paper also showed evidence of a large boulder more than a 100 feet across moving several hundred feet over a period of seven months.

The second paper showed various changes in a number of depressions and scarps on the smooth flat surfaces near the narrow neck that connected the comet’s two lobes. Examples of this terrain can be seen in high resolution pictures here and here and here and here.

From this data scientist suggest that the neck region is slowly dissolving away, its material in these flat areas flying away because the neck happens to be a region of low gravity.
