Land of stucco and lava-filled cracks

Stucco and filled cracks on Mars
Click for full image.

Cool image time! The picture on the right, cropped and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter in December 2018 and released earlier this year. It shows a filled fault/fissure in a region dubbed Cereberus Palus, located south of the giant volcano Elysium Mons and to the west of Olympus Mons. This region is also biggest and most extensive sections of the transition zone between Mars’s southern highlands and the northern lowlands. This area however is so far from the lowlands its geology is more likely influenced more by the volcanism that created Elysium Mons to the north.

Overview map

The overview map to the right illustrates this geography, with the black square indicating the location of this image.

The image itself strengthens my uneducated conclusion. This region of Cereberus Palus is filled with many faults, cracks caused as the terrain was stretched by the rising volcano. In some cases, as shown here, the cracks became filled with lava from below, as indicated by the lighter color of the material in those filled cracks..

What struck me most about this image was the terrain on the picture’s right. Looks exactly like the stucco on the outside of my house. It is as if a plasterer came by before the lava solidified and ran his putty knife over the surface to create the multiple small ridges.

It is worthwhile checking out the full resolution image. The details are especially intriguing.

Rules for commenting now posted permanently

12:54 pm

My very simple rules for commenting on Behind the Black have now been added to the right column (seen at the bottom of the page on mobile devices), placed just above the box listing the last ten comments. The rules are hardly odious:

I welcome all opinions, even those that strongly criticize my commentary.

However, name-calling and obscenities will not be tolerated. First time offenders who are new to the site will be warned. Second time offenders or first time offenders who have been here awhile will be suspended for a week. After that, I will ban you. Period.

I have stated these rules in posts in the past. Now they are permanently displayed at a place where I think all commenters will see them. There will therefore be no excuse for violating them in the future.

House proposes streamlined Space Corps within Air Force

12:09 pm

The House Armed Services Committee has proposed a streamlined Space Corps operating within the Air Force.

The bipartisan agreement calls for a single four-star general in charge of Space Force, compared with the three four-star generals the administration envisioned. It would also have fewer personnel transferred from other services into the Space Force, Smith said. “The main difference from the administration’s approach is less bureaucracy,” Smith said.

This is largely the same plan the committee endorsed in the House’s version of the 2018 NDAA, he said. The Senate Armed Services Committee, which has endorsed Trump’s plan, rejected Space Corps and the language did not make it into the final bill.

As always in Washington, the battle is between those who want to increase the size, power, and wealth of government, and those who wish to shrink it, while making it more effective (something it has not been for decades). The Democratic House plan appears to be taking the latter approach, while the Republican Senate wants the former.

Note how the partisan politics here are reversed. The Democrats in the House are pushing for smaller and more efficient government, and the Republican Senate is opposed, preferring a big unwieldy and unneeded Space Force instead.

In other words, politicians from both parties are not to be trusted. We need to make them all understand that we are watching, and that they will lose at the polls if they choose to expand this bankrupt government.

As for this House proposal, I am encouraged that the House is still pushing it. Hopefully the Senate will finally get on board.

Ginsberg extols Kavanaugh for hiring female law clerks

9:57 am

Supreme Court justice Ruth Bader Ginsberg yesterday extolled fellow justice Brett Kavanaugh for hiring the most female law clerks of any previous justice.

Ginsburg, in prepared remarks to a conference for judges in New York, noted that while women have made progress towards equal representation among the court’s clerks there are areas where improvements are still needed. “Justice Kavanaugh made history by bringing on board an all-female law clerk crew. Thanks to his selections, the Court has this Term, for the first time ever, more women than men serving as law clerks,” she said, according to remarks released by the court.

During Kavanaugh’s nomination hearing he promised to do this, and has followed through, putting the lie to all the evil slanders the Democrats accused him of during those hearings.

As I wrote on American Greatness in October,

Now is the time to look these bullies in the eyes, and tell them that we will not be intimidated, that we will stand for what we believe, and we will not bow to their smears and slanders and screaming protesters who know nothing of us, care nothing for us, and are increasingly willing to harm us and our children because we reject their oppressive and overbearing demands.

Kavanaugh has done this. And so has Ginsburg now. She is considered a hero by the same leftists that slandered Kavanaugh, and she is now telling those slanderers they were full of bunk. Good for her!

Trump announces immigration deal with Mexico, suspending tariffs

9:08 pm

President Trump today announced that an immigration deal has been worked out with Mexico, and that he is indefinitely suspending the tariffs he was going to impose on imports from that country.

A “U.S.-Mexico Joint Declaration” released by the State Department late June 7 outlined the details of the deal, saying the U.S. “will immediately expand the implementation” of a program that returns immigrants who cross the southern border to Mexico while their claims are adjudicated. Mexico will “offer jobs, healthcare and education” to those people, “according to its principles,” the agreement stated.

Mexico has also agreed, it said, to take “unprecedented steps to increase enforcement to curb irregular migration,” including the deployment of the Mexican National Guard throughout the country, starting June 10, especially on its southern border with Guatemala. And Mexico is taking “decisive action to dismantle human smuggling and trafficking organizations as well as their illicit financial and transportation networks,” the State Department said.

The agreement calls for more negotiations over the next ninety days.

We shall see. These kind of government deals never seem to accomplish what they promise, so I therefore remain skeptical Mexico will do much to stem the tide of illegals flowing through their country to the U.S.

White House to allow ISS commercialization, including tourists

2:27 pm

Capitalism in space: The White House today released an interim proposal [pdf] that would allow private enterprise on ISS, including allowing American private companies to fly tourists to the station.

A new interim directive from NASA allows private companies to buy time and space on the ISS for producing, marketing, or testing their products. It also allows those companies to use resources on the ISS for commercial purposes, even making use of NASA astronauts’ time and expertise (but not their likeness). If companies want, they can even send their own astronauts to the ISS, starting as early as 2020, but all of these activities come with a hefty price tag.

This fits with the Trump administration’s overall push to shift the American space effort from a NASA “program” to an independent and profitable American space industry.

Will this work? I cannot see how it can’t. At a minimum, it will tell us if there really is a viable market for space tourism and industry on the space station.

For the Russians this is another disaster. They had planned to sell the available seats on their Soyuz, no longer used by NASA astronauts, to tourists. It is very likely that business will shift to the U.S. manned capsules being built by SpaceX and Boeing.

Park Service removes signs saying glaciers to be gone by 2020 and 2030

12:19 pm

The National Park Service has finally recognized reality and removed or changed its displays at Glacier National Park that as recently September 2018 had said that the glaciers would be gone by either 2020 and 2030.

At the same time, the park service is still clinging, quite bitterly if you ask me, to its religious faith in global warming, even though the glaciers in the park have not been shrinking at all in recent years.

The National Park Service (NPS) quietly removed a visitor center sign saying the glaciers at Glacier National Park would disappear by 2020 due to climate change.

As it turns out, higher-than-average snowfall in recent years upended computer model projections from the early 2000s that NPS based its claim glaciers “will all be gone by the year 2020,” federal officials said.

“Glacier retreat in Glacier National Park speeds up and slows down with fluctuations in the local climate,” the U.S. Geological Survey (USGS), which monitors Glacier National Park, told The Daily Caller News Foundation. “Those signs were based on the observation prior to 2010 that glaciers were shrinking more quickly than a computer model predicted they would,” USGS said. “Subsequently, larger than average snowfall over several winters slowed down that retreat rate and the 2020 date used in the NPS display does not apply anymore.”

NPS updated signs at the St. Mary Visitor Center glacier exhibit over the winter. Sign changes meant the display warning glaciers would all disappear by 2020 now says: “When they completely disappear, however, will depend on how and when we act.” [emphasis mine]

The highlighted text illustrates the political agenda of the park service, something they have no mandate to have.

If you want to see how stupid the signage was, read my report when Diane and I visited Glacier in summer of 2017. As I wrote then,

The park’s sloppiness and political posturing here however does serve to produce one good, though certainly unintended, result. It helps to discredit the National Park Service’s global-warming activism, which hasn’t been based on good science for quite awhile. It will also help to raise the skepticism of ordinary park visitors, who will either notice the contradictions, or laugh at the absurdity of the prediction that the glaciers will vanish only three years hence.

I guess the park service finally got tired of dealing with the ridicule.

Virgin Orbit sues OneWeb over canceled launches

10:15 am

Capitalism in space: Virgin Orbit this week filed a lawsuit against the satellite company OneWeb for its cancellation of 35 of 39 launches.

According to a complaint Virgin Orbit filed June 4 in U.S. District Court for the Southern District of New York, OneWeb quietly canceled 35 of a planned 39 launches last June, triggering a $70 million termination fee spelled out in the contract. Virgin Orbit says OneWeb still owes $46.32 million. The lawsuit was first reported by Law360.com.

The real significance of this story is the decision of OneWeb to back out of its deal with Virgin Orbit. Richard Branson is an investor in both, which is why I think Virgin Orbit got the contract originally, when they were nowhere close to flying.

The timing of OneWeb’s cancellation in June 2018 is interesting. In July 2018 Virgin Orbit announced that it had received a launch license from the FAA for a flight it hoped to do before the end of the summer. That flight never happened.

So, did OneWeb’s cancellation cause the Virgin Orbit flight schedule to stall, or did OneWeb realize in June 2018 that the schedule was unrealistic, and that it was time to get out?

Either way, the lose of this income is a serious blow for this Branson company, and probably does explain the lack of flights in the past year.

If I was to rank the American smallsat orbital rocket companies at this point, Rocket Lab leads, with Vector and Firefly tied for a distance second. I would also consider EXOS Aerospace up there among the leaders, even though they are not yet building an orbital rocket. Instead, they are flying their reusable SARGE suborbital rocket on commercial flights (the next is scheduled for June 30), and using it as a guide for developing the orbital rocket to follow. Virgin Orbit should be among these leaders, but the lose of this contract and their failure to fly as scheduled makes me want to lower them in the rankings.
