Future of InSight’s heat probe dim
Blocked after drilling down only one foot instead of fifteen, engineers are increasingly worried that they will not be able to get InSight’s heat probe past whatever is blocking to so it can begin getting data of Mars’s inner thermal environment.
They are considering a bunch of options, including using InSight’s robot arm to either give the probe a nudge to help it get past the obstruction, or even use the arm to push the probe.
None of the options are encouraging it seems.

A decade of changes at the Martian south pole
Click for full image.
The image above, cropped, reduced, and annotated to post here, was released this week by the Mars Reconnaissance Orbiter (MRO) team. It shows the changes that have occurred at one location at the Martian south polar cap in the past decade. As planetary geologist Alfred McEwen wrote,
The south polar residual cap of carbon dioxide ice rapidly changes. This image was planned as an almost exact match to the illumination and viewing angles of a previous one we took in August 2009.
The pits have all expanded and merged, and we can just barely see the patterns in the 2009 image compared to this January 2019 picture. The 2009 image is also brighter and bluer, with more seasonal frost and/or less dust over the surface. These images were both taken in late southern summer, but our 2019 picture is slightly later in the Martian season by about two weeks.
You can get a better idea how much is changed by seeing the full image from which the above small area was cropped.

The Viking landers and its possible discovery of extraterrestrial life
Link here. One of the scientists involved in the Viking project has written a memoir of her experience, and the article interviews her.
Patricia Straat served as co-experimenter on one of the most controversial experiments ever sent to Mars: the Labeled Release instrument on the Viking Mars landers. The experiment’s principal investigator, Gilbert Levin, insists to this day that the project found extraterrestrial life. Most scientists doubt this interpretation, but the issue has never been fully settled.
Read it. It illustrates how uncertain science can be, even when an experiment produces a result that everyone involved dreamt of. As Straat notes,
The results met the pre-mission definition of a positive life response. But of course as soon as we got it everyone came up with alternative proposals to account for the results nonbiologically.
The problem was that though their experiment found evidence of life, none of the other Viking experiments did. Most significant was the apparently complete lack of organic material (based on carbon) in the soil.
To this day, no one has a good explanation for these results on Viking. The results remain a mystery, one that really will only be solved when we can return to Mars in force, and find out what it is really like.

Global map of Bennu
The OSIRIS-REx science team today released a global map of Bennu, compiled from images taken in December.
The map is above. It was released with no commentary. In comparing it with this global map of Ryugu, created by the Japanese probe Hayabusa-2, I am struck by how much both asteroids resemble each other.
This fact is in many ways a first. Since the first planetary probes left Earth in the 1960s the one reliable expectation that has consistently proven true is that no planetary object, be it planet, dwarf planet, moon, asteroid, or comet, was going to resemble any other planetary object. Each has been entirely unique, and unique in very startling and obvious ways.
Ryugu and Bennu represent the first planetary objects that actually look pretty much the same. Scientist will of course be able to note differences, but overall these objects clearly belong to a specific class of asteroids, which in this case is the rubble pile.
In a sense, this similarity marks a significant advancement in our knowledge. Up until now, we had observed so few objects that our knowledge base wasn’t large enough to start seeing patterns within our general classifications of planet, asteroid, or comets. That is now finally changing.

Boeing confirms delay till August for first unmanned Starliner launch
No surprise here: Boeing today confirmed that it is delaying until August for first unmanned Starliner test launch.
A statement issued by Boeing on Tuesday confirmed previous reports that the company’s CST-100 Starliner spacecraft, designed and built under a $4.2 billion contract from NASA, would miss its previous target launch date for an unpiloted test flight to the International Space Station in April. NASA and industry sources have said for months that an April launch date was not feasible, but NASA and Boeing had not officially published a revised schedule since early February.
The first Starliner test flight with astronauts on-board was previously scheduled for August. In Boeing’s schedule update released Tuesday, the company only said it expects the Crew Flight Test to occur “later this year,” but sources said the Starliner could fly with astronauts in November, at the earliest.
It appears that the fuel leak during a thruster test in June of last year has been the main cause of the delay.
None of this should effect SpaceX, which is primed to fly its mission during the summer. It does however cause more problems for Boeing, which is now also faced with pressure to finish NASA’s SLS rocket, bogged by years of delays and cost overruns.

How not to fall for modern news propaganda
Mollie Hemingway of The Federalist yesterday posted a very cogent and honest essay entitled, “Here’s Why I Didn’t Fall For The Russia-Trump Conspiracy.”
To preface, during the past two years Hemingway, along with a small cadre of honest Washington reporters, maintained their objectivity and did not fall for the Russian collusion scam. Instead, they documented the absurdity of the mainstream press’s claims and its never-ending “bombshells” (all of which ended up to be duds).
Hemingway outlines how, living deep within that Washington press culture, she at first found it difficult to resist peer pressure to accept the anti-Trump claims. She then describes how she did come to resist, and concludes as follows:
I didn’t fall for the Russia hoax that CNN and other media outlets did because I worked hard at understanding the appeal of his candidacy even before the Russia narrative started. At the same time, I recognized how disruptive he was to the established order and the livelihoods of those who had grown comfortable in D.C. Unlike many reporters, I knew and loved many people who voted for Trump. My background as a media critic made me aware of information campaigns and how to resist them. My dislike of the interventionist foreign policy made me less susceptible to scaremongering about realist foreign policy.
Her essay is worth reading because it provides a nice summary of the dishonesty rampant the past two years in the leftist press and Washington culture.
Reading her essay, however, made me wonder why I never fell for the Russia-Trump conspiracy. The answer was obvious. Hemingway, seeped in that mainstream press culture, as a Washington reporter, found increasingly she had to check what that press was telling her, and repeatedly found what it was saying was a lie.
I however long ago realized how dishonest and untrustworthy that mainstream press is, and thus have not relied on it for information, in the slightest, for about two decades. When a news source routinely gets its story wrong and then does nothing to correct the problem, I then decide that news source is not a source I will rely on for information.
For the past two years I have routinely ignored the anti-Trump claims and “bombshells” put forth by the NY Times, Washington Post, CNN, MSNBC, NBC, CBS, ABC, and all the other mainstream news sources. I simply don’t go to them for information. I knew from much experience that information would be wrong, and not worth the electrons that broadcast it.
Thus, I found it easy to dismiss as hogwash their claims that Trump was an agent for Russia. I already knew the people making the claim were clowns not to be listened to.
Does that make me uninformed or close-minded? No. Instead, I avoid being misinformed, as the facts I dig up from many other news sources, checked against each other, generally turn out to be trustworthy.
Everyone in the U.S., going forward, should keep this in mind. These leftist news sources are merely propaganda operations for the Democratic Party. If you rely on them for information you will definitely not know what is going on. Instead, you will be a puppet for that political party, someone unfit to call themselves a free citizen of a free nation.

CNN reporter advocates censorship by the FBI
Words fail me: In an interview of former FBI head James Comey, CNN’s Christiane Amanpour actually had to have the first amendment explained to her by Comey after she suggested that the FBI should act to censor speech it considers “hate speech.”.
“Of course, ‘lock her up’ was a feature of the 2016 Trump campaign,” Amanpour said. “Do you in retrospect wish that people like yourself, the FBI, I mean, the people in charge of law and order, had shut down that language — that it was dangerous potentially, that it could’ve created violence, that it’s kind of hate speech. Should that have been allowed?”
Comey explained the First Amendment to Amanpour, replying, “That’s not the role for government to play. The beauty of this country is people can say what they want, even if it’s misleading and it’s demagoguery.” [emphasis mine]
I am no fan of Comey, as I think he was a willing participant in the effort at the FBI to illegally overturn the 2016 election of Trump. However, he at least has a basic understanding of the Constitution, the fundamental law of the land. For a reporter at a national cable network to not understand this is horrifying.
The video of Amanpour’s comments is posted below the fold. The clip begins with Amanpour giving Comey a platform to condemn any possible investigation into the FBI’s abuse of power. Not surprising, as he and others remain very vulnerable in this matter.
Amanpour then wonders why that the FBI didn’t shut down free speech she and Comey didn’t like. Also not surprising, coming from an employee of a network whose sole purpose these past two years has been to overthrow the legal election of Trump, in league with that corrupt FBI.
And CNN wonders why Trump calls them “fake news”.

More Martian Pits!
As I said in my last post in February showing recent pit discoveries on Mars, I could almost make this a monthly series. In the March image download from the high resolution camera of Mars Reconnaissance Orbiter (MRO) were three (maybe four) more pits, all likely skylights above lava tubes and all located near the giant volcano Arsia Mons in the region dubbed the Tharsis Bulge. The image to the right shows all three, with a possible fourth just northwest of pit #2 and visible in its full image. For the full images of the other two pits go here (#1) and here (#3). In all three cases, click on the “black & white map projected” link to see the full image with scale.
The overview map on right shows where these three pits are located. If you compare this map with my previous overview maps from November 12, 2018 and February 22, 2019 you can see that while these pits are all found on the volcanic slopes surrounding Arsia Mons, they are all different pits. Moreover, the ten pits listed in these three posts are only a small sampling of the more than hundred already found.
Whether these pits are deadend sinks or skylights into underground lava tubes that connect is at this point unknown. It would be a reasonable speculation to assume that some are deadends, and some link to extensive tubes of varying lengths. It would also be dangerous. Mars is alien. While the geology will be based on the same physical laws found on Earth, the lighter gravity is going to produce things differently.
The three images above however do show some intriguing details.

Professor fired for challenging new fad of letting children pick their sex
They’re coming for you next: A University of Louisville (Kentucky) professor, fired for saying it is a bad idea to allow children to pick their sex, is suing the university.
The guy was chief of the university’s Division of Child and Adolescent Psychiatry and Psychology. and merely said that it is a mistake to pump drugs into little kids just because they express confusion about sex.
Young children have nowhere near the life experience necessary to ‘decide’ they want to be a different sex. “When you think of it, children don’t know much about anything — and I say this with respect — I’ve raised three…but they don’t know anything at the age of 7, 8, or 9. Why should we listen to a 9-year-old about what time they’re going to bed?” Josephson said. “We don’t let them vote, we don’t let them drive, and so are we going to let them at the age of 8 or 9 decide they are no longer male or female? Unbelievable!”
…Instead of just putting young children on meds that block puberty development and cross-sex hormones, Josephson recommends a ‘go-slow’ approach (to, you know, let the kid grow up a little and get some more life experience). “In actuality, Dr. Josephson never refuted the existence of gender dysphoria; he simply advocated a different method for treating individuals experiencing it,” says the lawsuit.
Josephson, according to the lawsuit, has warned that trying to change one’s sex “often involves permanent social, medical, psychiatric, and other consequences that cannot be fully appreciated until adulthood (e.g., psychopathology, suicidal behavior, peer rejection, and permanent sterility).” He also noted that some kids and even teens who go through gender dysphoria will cease to experience it by late adolescence.
It appears the gay studies community at the university, upon hearing this professor’s opinions, then rallied to get him removed, with the full cooperation of university’s management.
Note that they aimed to get him fired because he expressed an opinion dissenting from the current gay agenda. How dare he! Such things are not allowed in today’s America. Doesn’t he know that the first amendment was designed to provide free speech only to some people, who have the right opinions. All others must shut up.

India’s Chandrayaan-2 lunar lander delayed until May
The new colonial movement: India has once again delayed the launch of its Chandrayaan-2 lunar lander, pushing the launch back to May.
Previously they had said they’d launch in mid-April.
The article implies that the month delay has to do with scheduling the lander’s arrival so that it arrives at the best time during the long lunar day.
This mission was originally set to launch in April 2018, then October 2018, then January 2019. Because of these delays, Israel’s Beresheet lunar lander leap-frogged them to the Moon, and now stands poised to make Israel the fourth nation to achieve a lunar landing, beating India.

Hayabusa-2 to make crater on Ryugu later this week
The new colonial movement: Hayabusa-2’s planned attempt to blast a crater on the surface of the rubble pile asteroid Ryugu is now set for later this week.
Hayabusa2 is scheduled to start its descent from 20,000 meters above Ryugu at around 1 p.m. Thursday, Japan time.
The probe is to continue to move down slowly and, at 500 meters above the surface, release a device called an impactor at around 11 a.m. Friday. The impactor is designed to explode 40 minutes later to fire a metal object into the asteroid’s surface at a speed of 7,200 kilometers per hour.
The original point of creating this crater was to allow visual access to the asteroid’s interior for geological study. Now it will also tell us exactly how cemented together this rubble pile is. The cobble might be held together tightly, or loosely. We shall see later this week.

Beresheet makes course adjustment just prior to entering lunar orbit
The Israeli privately-funded lunar lander Beresheet yesterday completed a one-minute engine burn to adjust its course slightly in preparation for entering lunar orbit on April 4.
This morning’s 72-second-long burn helped make some “final adjustments” ahead of capture into lunar orbit, mission team members said in an update this morning. It’s unclear if any further such tweaks will be needed. “The teams are assessing the results to determine if another alignment will be required before Beresheet enters the lunar orbit this Thursday,” project team members said.
The image to the right was taken by Beresheet of the Earth during its last close approach on March 31. It appropriately shows the Middle East, with the Arabian peninsula visible just below center.
The landing is still scheduled for April 11.

Vector delays next test launch until June
Capitalism in space: Vector Launch has now delayed its next suborbital test launch three months to June.
Previously they had hoped to get this suborbital test launched in March/April. The company has not set any firm date in June, and cautions that further delays should not be unexpected. Assuming this suborbital launch happens this summer, they then hope to get their first orbital rocket launched by the end of the year.

Yutu-2 and Chang’e-4 awake for fourth lunar day
The Chinese rover Yutu-2 and lander Chang’e-4 were awakened on March 30, 2019 to begin work for their fourth lunar day on the surface of the Moon’s far side.
The rover was designed to last for three lunar days, but much like NASA missions that regularly outlive their initial mandates, Yutu 2’s mission may stretch on longer, the Chinese space agency hopes. (The current rover’s predecessor, Yutu, lost its roving ability on its second day on the moon.)
The China Lunar Exploration Program, which heads up the mission, has not provided any details about its scientific plans for the fourth day of Chang’e 4, which is focused on exploring the far side of the moon and how it differs from the near side.
Based on the images taken by Lunar Reconnaissance Orbiter, it appears they will be heading west, following the smoothest route away from Chang’e-4. This will place Yutu-2 in an area of small craters.

Chick-fil-A banned from another airport
They’re coming for you next: A second airport has decided to not allow a Chick-fil-A franchise there because its owners are conservative.
New York Assemblyman Sean Ryan, a Democrat, celebrated the decision by the Niagara Frontier Transportation Authority (NFTA) and Delaware North to not move forward with plans to bring Chick-fil-A to the Buffalo Niagara International Airport. “A publicly financed facility like the Buffalo Niagara International Airport is not the appropriate venue for a Chick-fil-A restaurant,” Mr. Ryan said in a statement Friday. “I applaud the decision that has been made to remove Chick-fil-A from the plans for this project.”
Mr. Ryan said he opposes the popular chicken chain because of its “long history of supporting and funding anti-LGBTQ organizations.” [emphasis mine]
And exactly what are the evil causes that Chick-fil-A support?
The criticism of Chick-fil-A’s donating practices was renewed last month after the left-wing ThinkProgress released a report saying the chain’s foundation donated $1.8 million in 2017 to Christian and socially conservative groups with an alleged history of anti-LGBTQ bias, including the Salvation Army. The allegations are part of an ongoing backlash against Chick-fil-A that started in 2012 after CEO Dan Cathy, a conservative Christian, revealed his disapproval of gay marriage.
In other words, you are no longer allowed to express any dissent to the idea of gay marriage. You must be silenced, your businesses destroyed, and your families hounded from public life. In fact, why not simply round all these evil Christians up and put them in concentration camps? That would be the best way to stop them from expressing their evil ideas in public.

Mars Express confirms Curiosity 2013 methane detection
The uncertainty of science: The Mars Express science team today announced that a reanalysis of the orbiter’s data showed the same spike spike of methane detection as seen by Curiosity on June 15, 2013.
The study exploited a new observation technique, allowing the collection of several hundred measurements in one area over a short period of time. The teams also developed a refined analysis technique to get the best out of their data.
“In general we did not detect any methane, aside from one definite detection of about 15 parts per billion by volume of methane in the atmosphere, which turned out to be a day after Curiosity reported a spike of about six parts per billion,” says Marco Giuranna from the Institute for Space Astrophysics and Planetology in Rome, Italy, the principal investigator for the PFS experiment, and lead author of the paper reporting the results in Nature Geoscience today.
“Although parts per billion in general means a relatively small amount, it is quite remarkable for Mars – our measurement corresponds to an average of about 46 tonnes of methane that was present in the area of 49 000 square kilometres observed from our orbit.”
Ten other observations in the Mars Express study period that reported no detections at the limit of the spectrometer’s sensitivity corresponded to a period of low measurements reported by Curiosity.
The data, along with their estimate about the source location for the methane, suggests that this was a geological event, not the result of biological life. They think the methane was trapped in ice-filled fissures, and released when that ice either broke or melted. Whether the methane itself was formed by past microbial life sometime in the past remains completely unknown.
To put it mildly, there are a lot of uncertainties in this result.

NASA head says that Falcon Heavy remains a future option for Orion
At an agency meeting for employees NASA administrator Jim Bridenstine reiterated that NASA is still seriously considering the use of SpaceX’s Falcon Heavy for future Orion lunar missions instead of SLS.
Bridenstine then laid out one scenario that has huge implications, not for a 2020 launch, but one later on. Until now, it was thought that only NASA’s Space Launch System could directly inject the Orion spacecraft into a lunar orbit, which made it the preferred option for getting astronauts to the Moon for any potential landing by 2024. However, Bridenstine said there was another option: a Falcon Heavy rocket with an Interim Cryogenic Propulsion Stage built by United Launch Alliance. “Talk about strange bedfellows,” he mused about the two rocket rivals.
This plan has the ability to put humans on the Moon by 2024, Bridenstine said. He then emphasized—twice—that NASA’s chief of human spaceflight, William Gerstenmaier, has yet to bless this approach due to a number of technical details. His reservations include the challenge of integrating the Falcon Heavy rocket in a horizontal position and then loading Orion with fuel in a vertical configuration on the launchpad. The Falcon Heavy would also require a larger payload fairing than it normally flies with. This would place uncertain stress on the rocket’s side-mounted boosters.
All the problems outlined in the second paragraph are the result of bad past management at NASA. Just as you design your rocket based the rocket engines you have — in order to save time and money — you design your capsule and manned vehicles based on the rockets that are available. NASA did not do this. It built Orion in a fantasy la-la land, without addressing the real world rocket options available. Now it has to either reconfigure, or get SpaceX to rethink the Falcon Heavy. Neither option will be cheap.
Regardless, Bridenstine’s statement is another shot across the bow to the porkmeisters in Congress. SLS is on shaky financial ground. It cannot compete in price with the commercial options. More significantly, it cannot come close to matching the launch rates of the private rockets. In the time NASA could put together one SLS launch, SpaceX could likely fly five to ten Falcon Heavies, and still do it for less money overall.
SLS is now tasked with a December 2020 deadline for launching that first unmanned test flight. Should it fail to meet that date, the political battle lines are now being laid for replacing it.

Circular feature on Mars?
Click for full resolution image.
Today’s cool image is cool for two reasons. First and foremost, the image, found in the archive of the high resolution camera of Mars Reconnaissance Orbiter (MRO), is titled “Circular Feature.” On the right is the full image, reduced to post here. I have searched it high and low, at low resolution as well as full resolution, and can find nothing, nothing at all, that invokes a circular feature to me.
This strange terrain is located very close to the southern icecap. If anything, the knobs and features that fill this image remind me of brain terrain, partly obscured by a layer of partly melted snow or frost. Nothing however seems circular in the slightest.
The second reason this image is cool is that it is very representative of its very large surrounding region. For what appears to be several hundred miles in all directions this is all that one can see, in a variety of MRO images, here, here, here, here, here, and here, to show only a few. Ever so often a craterlike feature pops out, like in the last example, but generally the surface continues in this undulating bland manner, endlessly. The only changing aspect is the dark streaks that cut across, likely dust devil tracks made over a long period of time.
Below the fold is a section of the full resolution image, at full resolution. It doesn’t really matter where I took the crop, as anywhere in the full image everything looks pretty much the same. The only slow change that I can perceive is that the surface seems to be descending to the north, with the lighter areas implying the existence of terraces.
Take a look, and try to figure out for yourself what is going on here.

Democracy comes to Turkey?
In local elections yesterday the party of Turkey’s long-time president Recep Tayyip Erdogan was pounded by several startling defeats.
The party of Turkey’s President Recep Tayyip Erdogan has lost control of the capital, Ankara, in local elections, in a blow to his 16-year rule.
The main opposition is also slightly ahead in the contest for mayor of Istanbul, figures published by the state-run Anadolu news agency suggest.
But the president’s AKP party is challenging the result in both cities.
Municipal elections were held across the nation on Sunday and an AKP-led alliance won more than 51% of the vote. [emphasis mine]
The article at the link hints at a depressed economy as the cause of these defeats, but I wonder if Erdogan’s recent moves trending in support of radical Islam also contributed. I also suspect that Erodgan’s support was actually a lot less than indicated by these numbers. Turkey is not really a democracy as an American would perceive it.
With most media either pro-government or controlled by Mr Erdogan’s supporters, critics believe opposition parties campaigned at a disadvantage. Mr Erdogan’s rallies dominated TV coverage.
The opposition pro-Kurdish Peoples’ Democratic Party (HDP) said the elections were unfair and refused to put forward candidates in several cities. Some of its leaders have been jailed on terrorism charges, accusations they reject.
I will not be surprised if the results flip in the coming week’s so that Erdogan’s party retains control in both cities. If this happens, however, I would also expect more turmoil there, as we are also seeing in many other places worldwide. Elections results recently have repeatedly slammed the status quo in places ruled by globalists, leftists, or Islamists. The establishment that has been in control then maneuvers things to nullify those elections.
The result: protests, violence, revolution, and bloodshed. Expect this in Turkey if the vote changes.

Comedian wins plurality in Ukrainian election; run-off April 21
A Trump-type non-politician who plays a comedian-turned-president has won a plurality in Sunday’s Ukrainian election, with a run-off between the two top vote-getters set for April 21.
Volodymyr Zelensky, who plays a fictional president in a popular TV show, secured 30.4 percent of the vote on Sunday, early results showed. Petro Poroshenko, a billionaire magnate and Ukraine’s current leader, received 17.8 percent. With no-one expected to secure a majority when the final results are confirmed later on Monday, the two largely pro-EU candidates are set to go head-to-head in a run-off vote on April 21.
Though his lead in the first election is large, no one should assume he will win the plurality.

India launches military satellite plus 28 smallsats
Capitalism in space: India today successfully used its PSLV rocket to launch one Indian military satellite plus 28 smallsats.
The rocket’s fourth stage demonstrated an additional capability.
Monday’s launch, the second of the year for India’s Polar Satellite Launch Vehicle (PSLV), was tasked with a series of maneuvers for the rocket’s upper stage to insert twenty-nine deployable payloads into their pre-planned orbits over the first two hours of its flight.
Following separation of the last payload, the upper stage will maneuver to a final orbit where it will operate as a research platform, hosting three attached payloads to demonstrate this capability for future missions. The launch also tests out a new configuration for the PSLV, a further intermediate between the lightest and heaviest versions of the rocket.
UPDATE: Yesterday China also launched a communications satellite designed to facilitate in-space communications, using its Long March 3B rocket.
The leaders in the 2019 launch race:
4 China
3 SpaceX
3 Europe (Arianespace)
2 Russia
2 India
The U.S. continues to lead China in the national rankings 6 to 4.

Cruz’s Space Frontier Act reintroduced; extends ISS to 2030
This week a bi-partisan group of senators reintroduced Senator Ted Cruz’s (R-Texas) Space Frontier Act.
The bill closely follows last year’s version of the Space Frontier Act, which Cruz and then-Sen. Bill Nelson (D-Fla.) shepherded through the Senate. Most of the bill covers efforts to reform commercial launch and remote sensing regulations in parallel with rulemaking activities currently underway by the Commerce and Transportation Departments. The bill also authorizes an extension of the International Space Station from 2024 to 2030 and elevates the Office of Space Commerce within the Commerce Department to the Bureau of Space Commerce.
They have changed one item that caused the House to reject the bill last year, one that exempted space-related bureaucracies from “the Federal Advisory Committee Act, which sets requirements for public meetings by such committees.” I suspect the exemption was an attempt to keep the job simple for these bureaucracies. At the same time, allowing them to function in the dark as they make regulations is not good either.
I have read through the bill [pdf], and my impression is that it really won’t change much. That it mandates the extension of ISS to 2030 however is important, as this means this big government project will continue to be funded, whether or not it makes sense to do so. Many in the space station private sector have said that it would be better that ISS was gone so that their efforts would not have to compete with it. I’m not sure this is true, however. All NASA really has to do to make ISS more commercially viable is to allow more commercial activities on it, including allowing private companies to attach their own modules that they own and control. Should NASA do this, the objections of the private space station community would become moot.
On a positive note, forcing NASA to continue to support ISS — which does have great value — will make it harder for NASA to find money for its Lunar Gateway boondoggle, a project that to my mind has far less obvious value, especially because it will cost far more than ISS to build and operate.

André Rieu – Hava Nagila
An evening pause: From the Wikipedia page:
Havah Nagilah…was composed in 1915 in Ottoman Palestine, when Hebrew was being revived as a spoken language after falling into disuse in this form for approximately 1,700 years, following the destruction of the Second Temple in 70 CE and the Bar Kokhba revolt in 132–136 CE. For the first time, Jews were being encouraged to speak Hebrew as a common language, instead of Yiddish, Arabic, Ladino, or other regional Jewish languages.
The lyrics reflect these events:
Let’s rejoice
Let’s rejoice
Let’s rejoice and be happy
Let’s sing
Let’s sing
Let’s sing and be happy
Awake, awake, my brothers!
Awake my brothers with a happy heart
Awake, my brothers, awake, my brothers!
With a happy heart
May we all sing with as much joy.

A look at the March 31 Ukrainian election
Link here. It appears to be a race between a Trump and two established politicians of mixed qualities.
The choice is stark.
Stay the slow and not-quite-steady course with a deeply unpopular but seasoned leader [incumbent President Petro Poroshenko] who knows the ropes and has taken Ukraine westward despite foot-dragging on reforms and a failure to tackle entrenched corruption.
Go with another veteran [former Prime Minister Yulia Tymoshenko], a political survivor with a dodgy past twice imprisoned by opponents who has lost two presidential elections but is banking on public disappointment and populist promises to carry her to victory.
Or take a chance on a comedian [Volodymyr Zelenskyy]with no experience in politics and governing but who has managed to tap into an antiestablishment mood similar to what’s brought unconventional leaders to power in the West by appealing directly to them for answers.
Right now, the comedian leads in the polls, and in looking at the videos at the link, it sure looks like he is trying to duplicate Trump’s success.
If no one gets 50% in the March 31 election, they will hold a run-off on April 21.

UK lawmakers reject all Brexit deals
The British parliament today rejected for the third and probably last time the deals negotiated by prime minister Teresa May in connection with her country’s exit from the European Union.
Right now it looks like the UK will leave the European Union on April 12, with no deal. While this possibility is causing heartache and terror among establishment politicians in Europe and Britain, it would honor the will of the voters, who voted to leave, period. The deals that have been offered have generally been a maneuver to nullify that vote.
Those establishment politicians have offered several new options to nullify the voters’ choice, including delaying the exit by a year to allow time for new negotiations, or offering a do-over election. Right now it looks like neither will happen, and Great Britain will leave.
Will an exit be good or bad? It is hard to say, but my sense is that it will be generally good for Great Britain, with most of the suffering focused among the establishment, who have used the EU as a means to power. An exit will strip them of this.

Scientists propose widespread deep groundwater on Mars
In a new study, scientists are now suggesting that widespread deep groundwater exists on Mars, and is the cause of the recurring slope lineae seen on many Martian slopes.
Previous theories for the cause of lineae proposed both dry and wet processes, all related to either near surface or atmospheric phenomenon. This new hypothesis is different, as it proposes deep groundwater as the source.
“We propose an alternative hypothesis that they originate from a deep pressurized groundwater source which comes to the surface moving upward along ground cracks,” Heggy says. “The experience we gained from our research in desert hydrology was the cornerstone in reaching this conclusion. We have seen the same mechanisms in the North African Sahara and in the Arabian Peninsula, and it helped us explore the same mechanism on Mars,” said Abotalib Z. Abotalib, the paper’s first author.
The two scientists concluded that fractures within some of Mars’ craters, enabled water springs to rise up to the surface as a result of pressure deep below. These springs leaked onto the surface, generating the sharp and distinct linear features found on the walls of these craters. The scientists also provide an explanation on how these water features fluctuate with seasonality on Mars.
This conclusion is most intriguing, but it is far from certain. Scientists have found a lot of lineae. For all of them to come from deep groundwater rising under pressure through fractures seems unlikely.
Nonetheless, this research indicates the growing belief among Mars researchers that water exists everywhere on Mars, and is accessible.
