Fractured surface in Occator Crater on Ceres

fractures in Occator Crater

Cool image time! Dawn, now in its final very close orbit above the surface of Ceres, has released some new images. The image on the right, cropped to post here, was taken from a distance of only 22 miles, and shows a fracture network and some very pronounced cliffs on the wall of Occator Crater. The sunlight is coming from the right. You can also see a bright spot on an east-facing slope with what looks like an apron of lighter avalanche material below it. The flat smooth surface of the floor of this same canyon is likely because it is filled with dust, which has ponded there.

These fractures suggest that the wall of the crater is undergoing a slow motion avalanche, with sections separating off and slowly sagging into the crater below, creating the fractures.

China launches two satellites

China today successfully launched what it called two “technology test satellites,” using its Long March 2C rocket.

No further information about the satellites was released. The Long March 2C is comparable to India’s PSLV rocket, and thus is used for smaller payloads.

The leaders in the 2018 launch standings:

18 China
11 SpaceX
7 Russia
5 ULA
4 Japan

This launch puts China ahead of the U.S. in the national race, 18-17, though SpaceX’s Dragon launch later this week should tie things up again.

Arianespace lowers its launch forecast for 2018

Capitalism in space: Because of a launch miscue in January and a decision by India to delay a satellite launch, Arianespace today admitted that it will not meet its forecast of fourteen launches in 2018.

Arianespace, majority-owned by a joint venture of Airbus and Safran, has so far conducted only three launches, but expects a busier second half, CEO Stephane Israel said. He now expects around 11 satellite launches for the year.

There might be a similar number of launches in 2019, but it is too early to give a definitive forecast, Israel said, adding the company was now focusing on gaining customers for the lower cost Ariane 6 rocket due to debut in 2020.

The article states the launch cost for Ariane 6 will be 40% less than Ariane 5, which cost $100 million per satellite. This brings the per satellite price for Ariane 6 to $60 million, about what SpaceX presently charges. Whether that can compete with the prices that SpaceX and others will be charging in 2020, when Ariane 6 is expected to become operational, remains unknown.

Grease in space

Based on observed data and lab recreations, astronomers have found that much of the galaxy’s interstellar dust is made of grease-like carbon molecules.

Organic matter of different kinds contains carbon, an element considered essential for life. There is though real uncertainty over its abundance, and only half the carbon expected is found between the stars in its pure form. The rest is chemically bound in two main forms, grease-like (aliphatic) and mothball-like (aromatic).

The UNSW / Ege team used a laboratory to create material with the same properties as interstellar dust. They mimicked the process by which organic molecules are synthesised in the outflows of carbon stars, by expanding a carbon-containing plasma into a vacuum at low temperature. The material was collected and then analysed by a combination of techniques. Using magnetic resonance and spectroscopy (splitting light into its constituent wavelengths) they were able to determine how strongly the material absorbed light with a certain infrared wavelength, a marker for aliphatic carbon.

β€œCombining our lab results with observations from astronomical observatories allows us to measure the amount of aliphatic carbon between us and the stars”, explained Professor Tim Schmidt, from the Australian Research Council Centre of Excellence in Exciton Science in the School of Chemistry at UNSW Sydney.

The researchers found that there are about 100 greasy carbon atoms for every million hydrogen atoms, accounting for between a quarter and a half of the available carbon. In the Milky Way Galaxy, this amounts to about 10 billion trillion trillion tonnes of greasy matter, or enough for 40 trillion trillion trillion packs of butter.

I guarantee that these results have a large margin of error. I also guarantee that they contain a significant element of truth.

House Judiciary Committee calls for impeachment or contempt for Rosenstein

On a partyline vote the House Judiciary Committee today passed a resolution requiring Deputy Attorney General Rod Rosenstein turn over their requested documents in seven days or face impeachment or contempt.

I don’t think Rosenstein is worried, yet. The resolution doesn’t mean much, since the wimpy Republican leadership in the House has to get it passed there, and then it has to pass in the Senate, filled with even more cowardly Republicans and the obstructionist Democrats. However, this increasing pressure might make Trump reconsider Rosenstein’s employment. Or it might make Trump force Rosenstein to turn over the documents, as he is constitutionally required to do.

The mysterious chaos terrain of Mars

In one of my weekly posts last month (dated May 14th) delving into the May image release from Mars Reconnaissance Orbiter’s (MRO) high resolution camera, I featured an image of what planetary geologists have labeled chaos terrain, a hummocky chaotic terrain that has no real parallel on Earth but is found in many places on Mars.

This month’s image MRO release included two more fascinating images of this type of terrain. In addition, the Mars Odyssey team today also released its own image of chaos terrain, showing a small part of a region dubbed Margaritifer Chaos. Below, the Mars Odyssey image is on the right, with one of the MRO images to the left. Both have been cropped, with the MRO image also reduced in resolution. The full MRO image shows what the MRO science team labels “possibly early stage chaos” on the rim of a canyon dubbed Shalbatana Vallis.

Supreme Court upholds Trump travel ban

In a 5-4 ruling the Supreme Court today upheld President Trump’s constitutional powers to enforce immigration law by upholding his travel ban.

Chief Justice John Roberts, writing for the majority, made it clear that the court viewed the ability to regulate immigration as squarely within a president’s powers and he rejected critics’ claims of anti-Muslim bias. “We express no view on the soundness of the policy,” Roberts wrote.

Moreover, the court also ruled today that fascist California cannot force pro-life centers to advertise pro-abortion announcements.

“The unlicensed notice imposes a government-scripted, speaker-based disclosure requirement that is wholly disconnected from California’s informational interest,” wrote Justice Thomas. “California has offered no justification that the notice plausibly furthers. It targets speakers, not speech, and imposes an unduly burdensome disclosure requirement that will chill their protected speech.”

Thomas also wrote that the law not only forced pro-life centers to promote abortion, but to do so while diminishing their own message on pregnancy care. “As California conceded at oral argument, a billboard for an unlicensed facility that says ‘Choose Life’ would have to surround that two-word statement with a 29-word statement from the government, in as many as 13 different languages,” continued Thomas.

“In this way, the unlicensed notice drowns out the facility’s own message. More likely, the ‘detail required’ by the unlicensed notice ‘effectively rules out’ the possibility of having such a billboard in the first place.”

The left is on a bad losing streak at the Supreme Court so far this year. And with the strong possibility that at least one of its liberal judges might soon be replaced by Trump, the left’s ability to impose its will through the courts should be further diminished.

The dying Russian space program

Three articles today illustrate starkly the sad state of the Russian space program.

The first story describes the serious problems for Russia’s first lunar probe in decades.

Its launch was originally scheduled for 2016 but was postponed to 2019 mainly because of lack of funding. Roscosmos allocated a budget of 4.5 billion rubles to NPO Lavochkin, Luna-Glob’s builder, as recently as October 2016.

Since then, almost everything has gone according to the plan, except with a crucial instrument called BIB, the probe’s inertial measurement unit. Provided by the Russian company NPO IT – located in the city of Korolyov, not far from ISS Mission Control – the BIB should provide the onboard computer with the necessary information to ensure guidance on the path from the Earth to the Moon.

However, BIB testing at NPO IT showed unexpected results, clearly indicating it was not working properly. The designers of this system noted it won’t be ready for the 2019 launch window, which resulted in NPO Lavochkin trying to replace it with a European equivalent called ASTRIX, designed by Airbus Defence & Space.

However, sanctions against Russia – from the European Commission in the fallout of the Ukrainian crisis – strictly forbid such a deal.

A different Russian instrument could replace BIB, but it won’t be ready in time, further delaying the mission to 2021 when many of its other instruments will be past their own due dates.

The second story describes the end of Russia’s Proton rocket, first built in the mid-1960s and since the 1990s has been its commercial workhorse. Faced with numerous failures and an inability to compete with SpaceX, it has lost its market share, and will now be replaced by Russia’s new Angara rocket. The problem is that Angara itself is not ready, and will likely not be operational until 2021, at the earliest.

The third article describes some of the reasons why Angara will take so long to be operational. Vostochny, Russia’s new spaceport, doesn’t have the necessary facilities, and it appears there is a disagreement within the Russian aerospace community about how fast those facilities can be built, or even if all are needed immediately. The top management in Roscosmos seems reluctant to switch all operations from Baikonur, probably for political reasons, while the expert quoted by the article says they should do it fast.

Either way, the entire Russian space program seems mired in bad technology, overpriced products, and poor and confused management. They have lost most of their commercial international customers, are about to lose NASA as well when Dragon and Starliner begin flying American astronauts, and do not have the resources to replace this lost income. Further, the top-down centralized management by the government of the entire aerospace industry has worsened these problems by stifling competition and innovation.

Russia might recover eventually, but for the next decade expect them to play a very minor role in space.

Judge throws out California climate lawsuits

A federal judge has tossed out climate lawsuits by San Francisco and Oakland against most of the largest oil companies, noting that the facts of the case make it a political one that should not be decided by a court.

“Although the scope of plaintiffs’ claims is determined by federal law, there are sound reasons why regulation of the worldwide problem of global warming should be determined by our political branches, not by our judiciary.

“…The dangers raised in the complaints are very real. But those dangers are worldwide. Their causes are worldwide. The benefits of fossil fuels are worldwide. The problem deserves a solution on a more vast scale than can be supplied by a district judge or jury in a public nuisance case.”

In other words, while the judge accepted the idea of human-caused global warming, he reiterated that it was not the court’s job to settle the matter.

That government officials in California wanted to bypass the political process (elections, the voters, open debate) and impose their will internationally by court order is another indication of the fascist mentality that is taking over that state.
