Big budget boost for ESA

8:49 am

The European Space Agency (ESA) received its largest budget increase ever, 20%, from its 22 member nations at a high level meeting yesterday.

The meeting also included commitments to remain a partner in ISS to 2030 and increase participation in Lunar Gateway. From the press release:

With worldwide partners, Europe will take its place at the heart of space exploration going farther than we have ever gone before – we continue our commitment to the International Space Station until 2030 as well as contributing vital transportation and habitation modules for the Gateway, the first space station to orbit the Moon. ESA’s astronauts recruited in 2009 will continue to receive flight assignments until all of them have been to space for a second time, and we will also begin the process of recruiting a new class to continue European exploration in low Earth orbit and beyond. European astronauts will fly to the Moon for the first time. Member States have confirmed European support for a ground-breaking Mars Sample Return mission, in cooperation with NASA.

ESA will help develop the commercial benefits of space for innovators and governments across the Member States, boosting competitiveness in the NewSpace environment. We will develop the first fully flexible satellite systems to be integrated with 5G networks, as well as next-generation optical technology for a fibre-like ‘network in the sky’, marking a transformation in the satellite communication industry. Satellite communications will join forces with navigation to begin satnav for the Moon, while closer to home commercial companies can access funding for new applications of navigation technologies through the NAVISP programme. ESA Ministers have secured a smooth transition to the next generation of launchers: Ariane 6 and Vega-C, and have given the green light to Space Rider, ESA’s new reusable spaceship.

Isn’t competition wonderful? ESA’s budget has been stagnant for years. Then SpaceX comes along and threatens its commercial market share while generating a new political will in the U.S. to renew its own space effort, and suddenly the European nations that make up ESA decide they need to do the same.

Much of the proposed program for ESA is very likely to happen, especially the commitments to a variety of astronomical and planetary missions. The agency’s commercial effort is also likely to happen, but whether it can happen fast enough to be competitive is questionable. As a government agency ESA’s track record in its effort to compete in the launch market has not been impressive. It took them far too long to accept the idea of reuseable rockets or the need to cut their costs drastically.

Lincoln’s Proclamation of Thanksgiving

10:30 am

Washington, D.C.
October 3, 1863

By the President of the United States of America.

A Proclamation.

The year that is drawing towards its close, has been filled with the blessings of fruitful fields and healthful skies. To these bounties, which are so constantly enjoyed that we are prone to forget the source from which they come, others have been added, which are of so extraordinary a nature, that they cannot fail to penetrate and soften even the heart which is habitually insensible to the ever watchful providence of Almighty God.

In the midst of a civil war of unequalled magnitude and severity, which has sometimes seemed to foreign States to invite and to provoke their aggression, peace has been preserved with all nations, order has been maintained, the laws have been respected and obeyed, and harmony has prevailed everywhere except in the theatre of military conflict; while that theatre has been greatly contracted by the advancing armies and navies of the Union. Needful diversions of wealth and of strength from the fields of peaceful industry to the national defence, have not arrested the plough, the shuttle or the ship; the axe has enlarged the borders of our settlements, and the mines, as well of iron and coal as of the precious metals, have yielded even more abundantly than heretofore. Population has steadily increased, notwithstanding the waste that has been made in the camp, the siege and the battle-field; and the country, rejoicing in the consciousness of augmented strength and vigor, is permitted to expect continuance of years with large increase of freedom.

No human counsel hath devised nor hath any mortal hand worked out these great things. They are the gracious gifts of the Most High God, who, while dealing with us in anger for our sins, hath nevertheless remembered mercy.

It has seemed to me fit and proper that they should be solemnly, reverently and gratefully acknowledged as with one heart and one voice by the whole American People. I do therefore invite my fellow citizens in every part of the United States, and also those who are at sea and those who are sojourning in foreign lands, to set apart and observe the last Thursday of November next, as a day of Thanksgiving and Praise to our beneficent Father who dwelleth in the Heavens. And I recommend to them that while offering up the ascriptions justly due to Him for such singular deliverances and blessings, they do also, with humble penitence for our national perverseness and disobedience, commend to His tender care all those who have become widows, orphans, mourners or sufferers in the lamentable civil strife in which we are unavoidably engaged, and fervently implore the interposition of the Almighty Hand to heal the wounds of the nation and to restore it as soon as may be consistent with the Divine purposes to the full enjoyment of peace, harmony, tranquillity and Union.

In testimony whereof, I have hereunto set my hand and caused the Seal of the United States to be affixed.

Done at the City of Washington, this Third day of October, in the year of our Lord one thousand eight hundred and sixty-three, and of the Independence of the United States the Eighty-eighth.

By the President: Abraham Lincoln

China launches Earth resource satellite

8:45 am

Using its Long March 4C rocket China yesterday successfully launched Gaofen-12, a remote sensing satellite designd to study Earth resources.

The leaders in the 2019 launch race:

27 China
18 Russia
11 SpaceX
7 Europe (Arianespace)

China now leads the U.S. 27 to 23 in the national rankings.

The launch schedule remains very busy, with a Rocket Lab launch set for early tomorrow and two launches to ISS (a Dragon and Progress) scheduled next week. In fact, seventeen launches are tentatively listed for launch in December, which would be once every other day. Several are unlikely, but regardless December will be a very busy month in the launch industry.

Further explorations at candidate Starship Mars landing site

4:02 pm

Beginning of Possible Glacial Unit near candidate Starship landing sites
Click for full image.

Close-up on exposed lower layer

Cool image time! Even though it appears that SpaceX has completed its first round of images of its candidate landing sites surrounding the Erebus Montes mountains in the Arcadia Planitia plains in the Martian northern lowlands, this does not mean that other planetary scientists are not asking for more images of this region, for their own scientific research.

The photograph on the right, cropped and reduced to post here, was released in the early November image download from the high resolution camera of Mars Reconnaissance Orbiter (MRO). Uncaptioned but dubbed “Beginning of Possible Glacial Unit,” it shows what appears at first glance to be a relatively featureless area south of Erebus Montes, out in the flat plains.

A closer look suggests otherwise. For one, the full image shows darker and lighter areas. The close-up to the right, its location indicated by the white box in the wider image above, also shows several intriguing depressions that appear to be revealing a knobby lower layer. In fact, in the full image it appears that the darker areas are areas where material has covered that knobby lower layer. Where it is bright the ground resembles the floors of these depressions, knobby and complex.

I do not know why they label this the “beginning” of a glacial unit. What I do know is that the research of this region has consistently found evidence of a lot of buried ice. To quote Donna Viola of the University of Arizona noted, “I think you could dig anywhere to get your water ice.” The knobby features to me suggest a surface that is showing signs of sublimation, where the exposed ice is slowly eroding. Think of what happens to a block of ice when you spray warm water on it. As it melts it leaves behind just these kinds of strange formations.

Overview of all MRO images at Starship candidate landing site

The red box in the map on the right shows the location of this photograph relative to the other images taken for SpaceX. The white boxes are the company’s images taken for Starship. The black boxes are the images it obtained in 2017 when it was thinking of sending a Dragon capsule to Mars.

This map does not show all images taken by MRO’s high resolution camera in this area, but the coverage is very scattered, with many gaps. Over time I suspect these gaps will be filled more quickly than other northern plain regions, because the scientists know that SpaceX has an interest in this area. That interest means there is an increased chance that a mission will fly here in the relatively near future, which in turn is going to generate more scientific interest as well.

China unfolds Dutch radio antennas on lunar relay satellite

9:48 am

Chinese engineers have unfolded and activated the Dutch radio antennas on Queqiao, their lunar relay satellite orbiting the Moon, an action that had been delayed because the lander Chang’e-4 and rover Yutu-2 had both exceeded their nominal mission on the surface.

The Chinese satellite was previously mainly seen as a communications satellite. However, the Chinese moon mission has by now achieved its primary goals. Consequently, the Chinese have redefined the satellite to be a radio observatory. As such, the Netherlands-China Low Frequency Explorer is the first Dutch-Chinese space observatory for radio astronomy.

Marc Klein Wolt, Managing Director of the Radboud Radio Lab and leader of the Dutch team, is happy: “Our contribution to the Chinese Chang’e 4 mission has now increased tremendously. We have the opportunity to perform our observations during the fourteen-day-long night behind the moon, which is much longer than was originally the idea. The moon night is ours, now.”

If Queqiao is now dedicated to being a radio antenna full time during the lunar night, I wonder if this means the Chinese are shutting down Chang’e-4 and Yutu-2. Up to now both spacecraft have only operated during the lunar night, which suggests that was the only time they could relay data. It is possible that data relay could take place at other times, and that the lander and rover can function autonomously, but I have my doubts.

Both Chang’e-4 and Yutu-2 functioned for twelve lunar nights, four times longer than planned, so shifting gears on Queqiao to do radio astronomy is not unreasonable. Unfortunately, the lack of transparency from China leaves us in the dark about the fate of Chang’e-4 and Yutu-2.

Does zero gravity cause intestinal issues?

9:23 am

The uncertainties of science: New research simulating microgravity on Earth now suggests that zero gravity might weaken the walls of the intestines.

The barrier function of the intestinal epithelium, he added, is critical for maintaining a healthy intestine; when disrupted, it can lead to increased permeability or leakiness. This, in turn, can greatly increase the risk of infections and chronic inflammatory conditions such as inflammatory bowel disease, celiac disease, Type 1 diabetes, and liver disease.

McCole’s team used a rotating wall vessel — a bioreactor that maintains cells in a controlled rotation environment that simulates near weightlessness — to examine the impact of simulated microgravity on cultured intestinal epithelial cells.

Following culture for 18 days in the vessel, the team discovered intestinal epithelial cells showed delayed formation of “tight junctions,” which are junctions that connect individual epithelial cells and are necessary for maintaining impermeability. The rotating wall vessel also produces an altered pattern of tight junction assembly that is retained up to 14 days after the intestinal epithelial cells were removed from the vessel.

This is good research, but it has not proved anything, merely indicated an area of research that needs a follow-up in space. I also wonder if there has been any evidence of this phenomenon from astronauts returning from long missions. As far as I know, intestinal issues have never been mentioned as a problem post flight.

Climate change protesters mob local UK spaceport council

9:04 am

Mob rule: A local Cornwall council meeting yesterday approved a $10 million grant for a new spaceport despite protesters screaming and yelling in the gallery and outside, forcing the meeting to end early.

After deciding not to defer a decision, councillors voted to grant £10.32m of capital funding to the spaceport by 66 to 34, with one abstention.

The gallery then erupted with chants as protesters launched paper airplanes. The chamber was then cleared of councillors and the meeting adjourned as the crowds continued to chant and shouted at councillors as they left saying things like “shame on you”. [emphasis mine]

Police were required to maintain order.

I have highlighted the vote count to note that these protesters clearly did not have that much real support. Their protests however remain a good intimidation tactic, so expect more protests if this project continues, especially because it appears the climate change crowd is beginning to behave as if any new technology is a threat. From the article it appears the protests were dominated by global warming activists from the group Extinction Rebellion. Also, “the groups Red Rebels and deathly-looking Penitents were joined by locals carrying signs and flags.”

I grant that it might not make sense for this local council to spend so much money for a spaceport, especially because they are doing it mostly for Richard Branson’s Virgin Galactic. They are likely to find the money wasted.

The protests however are mindless and an act of bullying, and are not the way to debate this or any subject sanely.

New image of Comet 2I/Borisov

1:22 pm

Comet 2I/Borisov
Click for full image.

Astronomers have taken a new image of the interstellar comet 2I/Borisov. The photograph to the right is that image, with the Earth placed alongside to show scale.

According to van Dokkum the comet’s tail, shown in the new image, is nearly 100,000 miles long, which is 14 times the size of Earth. “It’s humbling to realize how small Earth is next to this visitor from another solar system,” van Dokkum said.

Laughlin noted that 2l/Borisov is evaporating as it gets closer to Earth, releasing gas and fine dust in its tail. “Astronomers are taking advantage of Borisov’s visit, using telescopes such as Keck to obtain information about the building blocks of planets in systems other than our own,” Laughlin said.

The solid nucleus of the comet is only about a mile wide. As it began reacting to the Sun’s warming effect, the comet has taken on a “ghostly” appearance, the researchers said.

The comet will reach its closest point to the Earth, 190 million miles, in early December.

More Martian pits, filled and unfilled!

12:33 pm

Pit in Ceraunius Fossae
Click for full image.

Overview of Ceraunius Fossae

Time for what has almost become a monthly pit report from Mars Reconnaissance Orbiter (MRO). The November image download from the spacecraft’s high resolution camera included two pit-related photographs, both very different. To the right is the first, cropped to focus on the pit and the immediate surrounding terrain. Below that is a wider overview map to provide the context.

This pit’s location is indicated by the white box at the southern end of a region dubbed Ceraunius Fossae, made of hundreds and hundreds of parallel north-south fissures extending more than seven hundred miles south of the giant volcano Alba Mons and caused when the ground was stretched from below, causing it to crack.

This surrounding terrain helps to explain the pit’s origin. First it is located in a north-south depression with a number of other less pronounced depressions. While these do not line up precisely, they still suggest that they are sinkholes where the surface material is draining downward into voids below. Normally the assumption would be the existence of a lava tube, but here the downward grade is very small. Instead, what is likely happening is that the ground is being stretched, causing cracks to form into which surface material slips downward.

The Ceraunius Fossae fractures are extensional features produced when the crust is stretched apart…. Mechanical studies indicate that a regional pattern of radiating graben and rifts is consistent with stresses caused by loading of the lithosphere by the enormous weight of the Tharsis bulge….Several generations of grabens with slightly different orientations are present in Ceraunius Fossae, indicating that stress fields have changed somewhat over time.

In addition to producing normal faults and graben, extensional stresses can produce dilatant fractures or tension cracks that can open up subsurface voids. When surface material slides into the void, a pit crater may form. Pit craters are distinguishable from impact craters in lacking raised rims and surrounding ejecta blankets. On Mars, individual pit craters can coalesce to form crater chains (catenae) or troughs with scalloped edges.

That’s what we see here. The pit is suggestive of a void below, but it is likely not going to be a long coherent underground passage but a serious of random gaps, aligned roughly along the larger crack and producing the various depressions on the surface.

Today’s second pit is of an entire different nature.

First detection of extended galactic magnetic field

9:51 am

Whale galaxy with magnetic filaments
Click for full image.

Astronomers have made the first detection in another galaxy of a magnetic field that extends out into the galaxy’s halo.

The image above, based on data from the Jansky radio telescope, illustrates what they found..

The spiral galaxy is seen edge-on, with its disk of stars shown in pink. The filaments, shown in green and blue, extend beyond the disk into the galaxy’s extended halo. Green indicates filaments with their magnetic field pointing roughly toward us and blue with the field pointing away. This phenomenon, with the field alternating in direction, has never before been seen in the halo of a galaxy.

“This is the first time that we have clearly detected what astronomers call large-scale, coherent, magnetic fields far in the halo of a spiral galaxy, with the field lines aligned in the same direction over distances of a thousand light-years. We even see a regular pattern of this organized field changing direction,” said Marita Krause, of the Max-Planck Institute for Radioastronomy in Bonn, Germany.

The galaxy, dubbed the Whale by the astronomers, is about 35 million light years away, and has a diameter of about 80,000 light years, slightly smaller than the Milky Way.

Astronomers find 19 more galaxies showing lack of dark matter

9:11 am

The uncertainty of science: Astronomers have discovered 19 more dwarf galaxies, now totaling 23, that appear to have significant deficits of dark matter.

Of 324 dwarf galaxies analyzed, 19 appear to be missing similarly large stores of dark matter. Those 19 are all within about 500 million light-years of Earth, and five are in or near other groups of galaxies. In those cases, the researchers note, perhaps their galactic neighbors have somehow siphoned off their dark matter. But the remaining 14 are far from other galaxies. Either these oddballs were born different, or some internal machinations such as exploding stars have upset their balance of dark matter and everyday matter, or baryons.

It may not be a case of missing dark matter, says James Bullock, an astrophysicist at the University of California, Irvine. Instead, maybe these dwarf galaxies have clung to their normal matter — or even stolen some — and so “have too many baryons.” Either way, he says, “this is telling us something about the diversity of galaxy formation…. Exactly what that’s telling us, that’s the trick.”

Since we do not know what dark matter is to begin with, finding galaxies lacking it only makes more difficult to create a theory to explain it. Something causes most galaxies to rotate faster than they should, based on their visible mass. What that is remains an unknown.

Russians launch military satellite

9:02 am

Using a Soyuz-2 rocket the Russians today successfully launched a classified military satellite from its spaceport in Plesetsk.

The leaders in the 2019 launch race:

26 China
18 Russia
11 SpaceX
6 Europe (Arianespace)

China continues to lead the U.S. in the national rankings, 26 to 23.

These numbers will change again later today if Arianespace successfully launches two communications satellites. They have been trying to launch now for three days, but minor technical problems and weather have stymied them.

Supreme Court allows Mann defamation case to proceed

2:01 pm

The Supreme Court today ruled that the defamation suit of global warming activist Michael Mann against the National Review and the Competitive Enterprise Institute can go forward.

On Monday, the Supreme Court denied a petition by the Competitive Enterprise Institute and National Review magazine to rehear and dismiss the defamation lawsuit brought by well-known climate scientist Michael Mann. The Competitive Enterprise Institute and National Review have been fighting for years to dismiss the case before it goes to trial, but the Supreme Court’s denial means the case will move forward in D.C. district court.

The Supreme Court rejected the petition without comment. But Justice Samuel Alito, a conservative, dissented, arguing that the case addresses critical freedom of speech and freedom of the press issues.

The court has basically ruled that Mann should be allowed his day in court. Since the case stems from criticism of Mann’s shoddy climate science work, I suspect he will find himself having problems once that day arrives, as he did in Canada.

The bad part of this is that it allows Mann to achieve part of his strategy, which is to chill any criticisms of his shoddy work, out of fear he will sue and thus cost the critic a lot of money mounting a defense. No one should be allowed to use the law as a weapon to prevent criticism, especially if that criticism successfully proves the nature of that person’s very shoddy and incompetent climate research, including faking data and hiding pertinent real data.

UPDATE: I have crossed out the words above because they misconstrued my intended meaning. Mann’s effort to use the law to try to squelch opposing points of view is wrong, but in a free society we must allow him this bad behavior. If the law functions properly, his misbehavior (and shoddy science work) will become very evident with time.

By the way, did I mention that Mann’s scientific work is generally very shoddy, and not very trustworthy?

A society run by mob rule

1:15 pm

In the past week several ugly events have illustrated forcefully how mob rule now dictates who can or cannot speak freely in America. Worse, these events show that we are no longer a civilized social order run by reason. Instead, we have become a culture where whoever can throw the loudest tantrum dictates policy.

First we have the horrible events last week at the State University of New York-Binghamton.

To understand how disgusting and despicable the first story above is, it is necessary for you to watch the video below. Pay special attention to the taller girl in the fur-lined parka who at about four minutes keeps looking at the camera-person (whom I think is also a girl) and aggressively and repeatedly asking, “Why are you shaking so? Why are you shaking so?” The reason is obvious. The girl filming is one the conservative students, and she is justifiably frightened. The taller girl, hostile and irrationally angry because a conservative dared to advocate opinions she doesn’t like, is clearly being physically threatening. As are all of her leftist compatriots.

The response of the college administration to this atrocious behavior was even more vile, essentially endorsing the actions of the mob:

Sweeping victories for pro-democracy protesters in Hong Kong elections

10:27 am

Good news: In elections yesterday in Hong Kong, pro-democracy candidates won a landslide victory, capturing control of 17 of 18 local councils.

Some 2.94 million people voted in the election, compared with 1.4 million in 2015.

Pro-democracy candidates won close to 60% of the total vote on Sunday, but achieved a landslide in terms of seats because of the first-past-the-post system, local media report. Pro-democracy contenders were victorious in 347 of the 452 district council seats up for grabs; pro-Beijing candidates won 60 seats; while independents – many of them pro-democracy – got 45, according to the South China Morning Post.

In the last election four years ago, pro-Beijing councillors won 298 seats, but the distribution of these seats meant they took control of all 18 district councils.

The official response from the China-appointed leader of the Hong Kong Special Administrative Region (HKSAR), Carrie Lam, was somewhat conciliatory:

After the social unrest in the past five months, I firmly believe that the vast majority of the public would share my wish for the peaceful, safe and orderly situation to continue.

The HKSAR Government respects the election results. There are various analyses and interpretations in the community in relation to the results, and quite a few are of the view that the results reflect people’s dissatisfaction with the current situation and the deep-seated problems in society. The HKSAR Government will listen to the opinions of members of the public humbly and seriously reflect.

Without doubt these results make it difficult for China to use military force on Hong Kong. The elected leadership throughout all but one district will oppose and stymie such actions. To make it happen the Chinese will literally have to arrest everyone.

In a sense, Hong Kong is becoming the West Berlin of China. It is now a path for ordinary Chinese citizens dissatisfied with communist rule to see another option. For totalitarian regimes, this is never a good thing, as when compared to free societies they never do better.

“Damaged cable” causes Russians to delay Progress launch

8:36 am

Because of the discovery of a “damaged cable” on a Progress freighter, the Russians have delayed its launch from December 1 to December 6.

On the morning of November 25, Roskosmos announced that issues had been found during the preparations of Progress MS-13 for launch. “Problems are now resolved and the checks of onboard systems are ongoing,” the State Corporation said. “There will be a separate announcement on the launch date…” the announcement said, hinting that the planned December 1 launch window was no longer valid. Before the end of the work day in Moscow on November 25, Roskosmos posted an update announcing that the launch of Progress MS-13 had been rescheduled for December 6, 2019, at 12:34 Moscow Time, due to an issue with an onboard cable found by specialists from RKK Energia. The problem was resolved after the replacement of the cable, the company said. According to a posting on the online forum of the Novosti Kosmonavtiki magazine, specialists spent past two days trying to find a source of electric charge on the body of the spacecraft and then discovered a damaged cable in the vehicle’s instrument compartment. [emphasis mine]

Considering the drillhole found in an earlier Soyuz capsule, I cannot help wondering if this damage was intentional. The Russians never revealed if they had identified the culprit of that earlier damage, and the reports from Russia today are somewhat vague about this new damage.

This Progress launch had earlier been rescheduled from December 6 to avoid a conflict with the launch of a Dragon cargo capsule. There is no word yet on how that conflict will be mitigated now that the launch is back on that date.

Home destroyed by Long March 3B 1st stage

8:27 am

It appears from a number of twitter-type sources coming from China that the spent first stage of the Long March 3B rocket that successfully launched two GPS-type satellites this weekend crashed onto a house, destroying it.

Video footage emerged on Chinese social media shortly after launch showing the apparent destruction of a rural building. Flames are seen within the building along with fumes from residual propellant rising from the booster wreckage.

…The first stage and four side boosters of the Long March 3B use a toxic hypergolic propellant combination of hydrazine and nitrogen tetroxide.

There have so far been no state media reports on the incident. The footage and social media comments suggest the owners returned home following standard evacuation ahead of launch.

According to other such reports, the home-owners will be compensated, but this is not confirmed.

Regardless, because of China’s effort to increase its launch rate, launches coming from its inland spaceports are either going to develop controlled landing for the expendable stages or will cease. The damage both to their own citizens as well as the bad press these crashes garner are aspects that the Chinese government will want to avoid, with the bad press likely its greater concern.

Nick Sandmann $275 million libel suit against NBC to proceed

10:31 pm

A judge has now ruled that the $275 million libel suit against NBC filed by Covington teen-ager Nick Sandmann can move forward.

A federal judge ruled Thursday that Covington Catholic student Nicholas Sandmann’s $275 million lawsuit against NBCUniversal may proceed on limited grounds, as he had with similar cases against The Washington Post and CNN.

U.S. District Court Judge William Bertelsman dismissed parts of the lawsuit while allowing discovery on allegations that the network’s coverage defamed the teen by reporting that he “blocked” Native American elder Nathan Phillips in a Jan. 18 encounter at the Lincoln Memorial.

…”As predicted, today Judge Bertelsman entered an order allowing the Nicholas Sandmann case against NBCUniversal to proceed to discovery just as he had earlier ruled with respect to WaPo & CNN cases. Huge, huge win!” tweeted Sandmann attorney L. Lin Wood.

Both the Post and NBC are very exposed here, especially when these lawsuits go before Kentucky juries. My big fear is that Sandmann’s lawyer will settle too easily, as these corrupt news organizations need to be slapped down hard for their routine effort to slander anyone on the right or even innocent who happens to do anything that appears to oppose the agenda of the Democratic Party or the left (I repeat myself).

Air Force to still limit launch contractors to two

10:09 pm

The bureaucracy wins again! Though Blue Origin’s protest of the Air Force’s planned launch contract rules was sustained, and the Air Force plans to revise its contracting rules accordingly, the Air Force today announced that because the ruling itself was somewhat limited, it will still be able to limit future bidding for launches to only two contractors, through 2026.

[T]he Air Force intends to award in mid-2020 five-year contracts to two providers. Four companies submitted proposals: Blue Origin, Northrop Grumman, SpaceX and United Launch Alliance.

Although Blue Origin challenged the Air Force’s decision to pick two providers as harmful to the industrial base, GAO had no objections to that approach. “On the whole, we are pleased that the GAO upheld the major components of the National Security Space Launch competition, especially award timelines, quantities, and period of performance,” said [Air Force acquisition executive Will] Roper.

If you read the article, you will discover why the Air Force still wants to limit to two the number of contractors who can bid on launches. Its rules and methods, as described, are so tortuousness and complex that I suspect even the Air Force doesn’t completely understand them. Thus, to deal with more than two bids individually for each launch is beyond the comprehension or ability of these military bureaucrats. Rather streamline their bidding rules, they have decided it is better to put limits on American private enterprise, raise costs for the taxpayer, and squelch innovation and fast development within the military space effort.

Mars Express confirms ancient glaciers in northern Martian mid-latitudes

9:46 pm

Perspective view of Deuteronilus Mensae
Click for full image.

The European Space Agency’s orbiter Mars Express has confirmed the presence of large fractured ice sheets suggestive of buried and ancient glaciers. These ice sheets are within one region on Mars located in the mid-latitudes where many such glacial features have been found. They are also in the transition zone between the northern lowlands and the southern highlands.

This landscape shows clear and widespread signs of significant, lasting erosion. As is common with fretted terrain, it contains a mix of cliffs, canyons, scarps, steep-sided and flat-topped mounds (mesa), furrows, fractured ridges and more, a selection of which can be seen dotted across the frame.

These features were created as flowing material dissected the area, cutting through the existing landscape and carving out a web of winding channels. In the case of Deuteronilus Mensae, flowing ice is the most likely culprit. Scientists believe that this terrain has experienced extensive past glacial activity across numerous martian epochs.

It is thought that glaciers slowly but surely ate away at the plains and plateaus that once covered this region, leaving only a scattering of steep, flat, isolated mounds of rock in their wake.

Smooth deposits cover the floor itself, some marked with flow patterns from material slowly moving downhill – a mix of ice and accumulated debris that came together to form and feed viscous, moving flows of mass somewhat akin to a landslide or mudflow here on Earth.

Studies of this region by NASA’s Mars Reconnaissance Orbiter [MRO] have shown that most of the features seen here do indeed contain high levels of water ice. Estimates place the ice content of some glacial features in the region at up to 90%. This suggests that, rather than hosting individual or occasional icy pockets and glaciers, Deuteronilus Mensae may actually represent the remnants of an old regional ice sheet. This ice sheet may once have covered the entire area, lying atop the plateaus and plains. As the martian climate changed this ice began to shift around and disappear, slowly revealing the rock beneath.

Overall, the data coming from both Mars Express and MRO increasingly suggests that there is a lot of buried glacial ice in the mid-latitudes. Mars might be a desert, but it is increasingly beginning to look like much of the planet is a desert like Antarctica, not the Sahara.

Chang’e-4 and Yutu-2 begin 12th lunar day

9:29 pm

Chinese engineers have reactivated both their lunar lander, Chang’e-4, and its rover, Yutu-2, for their twelve lunar day on the far side of the Moon.

The lander woke up at 5:03 p.m. Thursday (Beijing Time), and the rover, Yutu-2 (Jade Rabbit-2), awoke at 0:51 a.m. the same day. Both are in normal working order, according to the Lunar Exploration and Space Program Center of the China National Space Administration.

No word on where Yutu-2 will be sent over then next two weeks.

Posting was light during the day today because Diane and I were on a hike that I needed to do for the upcoming planned second edition of my hiking guidebook, Circuit Hikes of Southern Arizona. My boss (me) allowed me to go, since this hike was not pure pleasure, but reconnaissance for one of my books.
