Europe initiates website to name ExoMars 2020 rover

July 21, 2018 9:26 am Robert Zimmerman

The European Space Agency has created a website where people can offer their suggestions to name the ExoMars 2020 rover.

Astronaut Tim Peake is leading the hunt for a great moniker. He wants everyone to go to a special website set up for the purpose and enter a suggestion. But don’t think “Spacey McSpaceFace” is a goer because this is not an online poll. All ideas will be put before an expert panel and it is they who will make the final choice.

If all goes right, 2020 should see two new rovers arrive on the Martian surface.

“They’re coming for you next.”

July 20, 2018 3:57 pm Robert Zimmerman

This week we had a number of really ugly examples of the hate the left has for anyone who might dare express an opinion that might suggest even the slightest support for President Donald Trump.

But then, how is this week different from any other week since Trump was elected president in 2016?

The top example however is how Judge Jeanine Pirro was treated when she appeared on the The View. I have embedded the video below. You must force yourself to watch. It is painful and ugly, but the hate and very clear close-mindedness of those who disagreed with her, especially from Whoopie Goldberg, illustrates well the terrible state we are in.

Most biomedical research cannot be replicated

July 20, 2018 9:13 am Robert Zimmerman

New studies looking at the work of scientists in the biomedical field has found that their research is difficult if not impossible to replicate, partly because much of their raw data is never made available for other researchers to review.

But over the past several years, a growing contingent of scientists has begun to question the accepted veracity of published research—even after it’s cleared the hurdles of peer review and appears in widely respected journals. The problem is a pervasive inability to replicate a large proportion of the results across numerous disciplines.

In 2005, for instance, John Ioannidis, a professor of medicine at Stanford University, used several simulations to show that scientific claims are more likely to be false than true. And this past summer Brian Nosek, a professor of psychology at the University of Virginia, attempted to replicate the findings of 100 psychology studies and found that only 39 percent of the results held up under rigorous re-testing. “There are multiple lines of evidence, both theoretical and empirical, that have begun to bring the reproducibility of a substantial segment of scientific literature into question,” says Ioannidis. “We are getting millions of papers that go nowhere.”

There’s a lot more. Read it all. It appears that much if not all of biomedical research is suspect. Their conclusions might be correct, but their methods are questionable, at best.

Trump administration proposes revisions to Endangered Species Act

July 20, 2018 8:58 am Robert Zimmerman

The Trump administration has proposed some regulatory revisions to Endangered Species Act that would scale back somewhat its sometime draconian powers.

The proposed regulatory changes are both technical and consequential. One, for instance, bears the deceptively dull title of “elimination of blanket 4(d) rule” (E&E News PM, 4 April). The ESA prohibits the “take” of species designated as endangered, while Section 4(d) of the law allows the agency to establish special regulations for threatened species. In 1978, FWS used this authority to extend the prohibition of take to all threatened species. This is known as the “blanket 4(d) rule.”

Take covers a wide range of actions, including those that “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture or collect” a threatened or endangered species. This blanket 4(d) rule for threatened species can be modified by a species-specific 4(d) rule.

Conservatives and private-property advocates have previously sought to scale back the blanket 4(d) rule, which they say erases what should be a meaningful distinction between threatened and endangered species. The proposal would cover only future listings. “Some of our regulations were promulgated back in 1986, and frankly, a great deal has been learned by the agencies administering the act and by the public,” Deputy Interior Secretary David Bernhardt told reporters today.

Another change would establish that the “foreseeable future” definition used in making ESA listing decisions extends only so far as officials “can reasonably determine that the conditions posing the potential danger of extinction are probable.”

A potentially key change involves critical habitats, which are areas important for recovery of a species. Sometimes an area can be considered important for recovery even when it is not currently occupied by the species in question. Under the new proposal, FWS and NOAA Fisheries will designate unoccupied critical habitat only when the occupied areas are inadequate to ensure the conservation of the species or if inclusion of unoccupied areas would yield certain other specified benefits.

In some “rare” cases, officials say, there may be no critical habitat designated.

The article above, from the journal Science, shocked me by its reasonable discussion of these proposed changes. I had expected an anti-Trump screed, similar to the original version of this Daily Mail article from yesterday. Today it reads more reasonably, but yesterday the article was far more devoted to airing opposition to the Trump proposals.

No matter. There is madness out there, it has taken possession of the entire anti-Trump community. It won’t make a difference how reasonable the administration’s proposals might be, there will be over-the-top declarations about the evils of these proposals and how they will destroy everything.

A detailed look at upcoming SpaceX launch recovery operations

July 19, 2018 11:19 pm Robert Zimmerman

Link here. They are expanding their drone fleet and their capsule recovery fleet. Though we should expect some big developments in the coming year, there was also this tidbit:

Earlier this year, the company’s president Gwynne Shotwell told CNBC that next year will see a decrease in the company’s launch cadence. The slip is due to a decline in the number of large geostationary communications satellites needing a launch.

Missions to a geostationary transfer orbit make up the majority of launches requiring a droneship recovery. Therefore, it is unlikely that two east coast droneships will be needed to support Falcon 9 over the next year or two.

It appears that after five years of effort, SpaceX has finally begun to clean out its backlog of contracted launches, caused by the initial development delays of the Falcon 9 and its two failures.

China developing a robot satellite refueling spacecraft

July 19, 2018 11:11 pm Robert Zimmerman

The new colonial movement: China today reported that it is developing a robot satellite that would attach itself to satellites that are out of fuel and use its own fuel to make the spacecraft usable again.

Hu Di, the chief designer of the vehicle, said compared with foreign research that focuses on refueling satellites that have run out of fuel, their option is much simpler and efficient. The vehicle will take about two years to complete.

Hu Di is wrong. In fact, I wonder if they have stolen this idea from Northrop Grumman, which as Orbital ATK has been developing a project exactly like this for several years.

Hayabusa-2 finds Ryugu covered with scattered large boulders

July 19, 2018 11:02 pm Robert Zimmerman

Hayabusa-2 has found that the asteroid Ryugu is covered with many scattered large boulders.

The Hayabusa 2 space probe discovered many boulders scattered on the asteroid Ryugu, suggesting it was formed from fragments of other celestial bodies, the Japan Aerospace Exploration Agency (JAXA) said July 19. More than 100 rocks larger than 8 meters in length were confirmed on the surface of the “spinning top” asteroid from images captured by Hayabusa 2, according to JAXA. The largest boulder was about 130 meters in length near the south pole.

The rocks are likely too big to be meteor fragments from collisions with Ryugu, which has a diameter of about 900 meters. “(The finding) is compelling evidence to prove that the Ryugu asteroid was formed by fragments of larger celestial bodies,” said Seiichiro Watanabe, head of the study team and professor of Nagoya University.

The asteroid’s slightly tilted axis of rotation gives Ryugu two seasons: summer and winter. Hayabusa 2 found the temperature ranged from about 20 to 100 degrees on Ryugu’s surface.

Surprise! This finding makes Ryugu very different from every other asteroid previously visited. Most have had relatively smooth surfaces, with lots of dust.

Global mosiacs of Titan in infrared

July 19, 2018 8:53 am Robert Zimmerman

Titan in infrared

The Cassini science team today released global infrared mosaics of Titan, created from images accumulated during the more than 100 fly-bys of the moon during the spacecraft’s thirteen years in orbit around Saturn.

The image on the right, cropped and reduced in resolution to post here, is only one such global mosaic. Go to the story to see them all.

Making mosaics of VIMS images of Titan has always been a challenge because the data were obtained over many different flybys with different observing geometries and atmospheric conditions. One result is that very prominent seams appear in the mosaics that are quite difficult for imaging scientists to remove. But, through laborious and detailed analyses of the data, along with time consuming hand processing of the mosaics, the seams have been mostly removed. This is an update to the work previously discussed in PIA20022.

Any full color image is comprised of three color channels: red, green and blue. Each of the three color channels combined to create these views was produced using a ratio between the brightness of Titan’s surface at two different wavelengths (1.59/1.27 microns [red], 2.03/1.27 microns [green] and 1.27/1.08 microns [blue]). This technique (called a “band-ratio” technique) reduces the prominence of seams, as well as emphasizing subtle spectral variations in the materials on Titan’s surface. For example, the moon’s equatorial dune fields appear a consistent brown color here. There are also bluish and purplish areas that may have different compositions from the other bright areas, and may be enriched in water ice.

New close-up images of Ceres

Cerealia Facula on Ceres

Cool image time! The image on the right, cropped and reduced in resolution to post here, is one of two images released today by the Dawn science team of the double bright spots found in Occator Crater, taken from the spacecraft’s tight final orbit above Ceres. This image shows what they have dubbed Cerealia Facula. The second image shows Vinalia Faculae.

This mosaic of Cerealia Facula is based on images obtained by NASA’s Dawn spacecraft in its second extended mission, from an altitude as low as about 21 miles (34 kilometers). The contrast in resolution obtained by the two phases is visible here, reflected by a few gaps in the high-resolution coverage. This image is superposed to a similar scene acquired in the low-altitude mapping orbit of the mission from an altitude of about 240 miles (385 km).

Inset of Cerealia Facula

The second image on the left is a crop at full resolution of the area in the white box above. This gives you a taste of the many interesting things found in the full resolution image. For example, the bright spots scattered throughout this image suggest they are recent upwellings from below. The ridgelines in the upper right are either the remains of the water-ice volcano they think once stood here but subsequently slumped back down to form a depression, or pressure ridges being pushed up by later upwellings.

The full image has lots more. So does the image of Vinalia Faculae. Check them out.

Chinese officials quite rightly dismiss LOP-G

July 18, 2018 11:07 am Robert Zimmerman

At a science workshop in Europe this week Chinese space officials made it clear that they found the concept of NASA Lunar Orbiting Platform-Gateway (LOP-G) to be unimpressive and uninteresting.

Moreover, they said that while it appears we will be delaying our landings on the Moon for at least a decade because of LOP-G, they will be focused on getting and building a research station on the surface, right off the bat.

Overall, Pei does not appear to be a fan of NASA’s plan to build a deep space gateway, formally known as the Lunar Orbital Platform-Gateway, at a near-rectilinear halo orbit. Whereas NASA will focus its activities on this gateway away from the Moon, Pei said China will focus on a “lunar scientific research station.”

Another slide from Pei offered some thoughts on the gateway concept, which NASA intends to build out during the 2020s, delaying a human landing on the Moon until the end of the decade at the earliest. Pei does not appear to be certain about the scientific objectives of such a station, and the deputy director concludes that, from a cost-benefit standpoint, the gateway would have “lost cost-effectiveness.”

The Chinese are right of course. LOP-G is merely a fake project to justify SLS and Orion, designed not to explore space but to provide Congress a jobs program on Earth. It will hand the Moon to China, while we dither in lunar orbit.

Entire Martian atmosphere appears to act as a single unit

July 18, 2018 10:32 am Robert Zimmerman

Using ten years of accumulated data from Europe’s Mars Express orbiter scientists have found that the Martian atmosphere appears to behave as a single unit, with changes its upper and lower levels closely connected.

“We discovered a surprising and significant increase in the amount of charged particles in the upper atmosphere during springtime in the Northern hemisphere, which is when the mass in the lower atmosphere is growing as ice sublimates from the northern polar cap,” adds Beatriz.

Mars’ polar caps are made up of a mix of water ice and frozen carbon dioxide. Each winter, up to a third of the mass in Mars’ atmosphere condenses to form an icy layer at each of the planet’s poles. Every spring, some of the mass within these caps sublimates to rejoin the atmosphere, and the caps visibly shrink as a result. “This sublimation process was thought to mostly only affect the lower atmosphere – we didn’t expect to see its effects clearly propagating upwards to higher levels,” says co-author Olivier Witasse of the European Space Agency, and former ESA Project Scientist for Mars Express. “It’s very interesting to find a connection like this.”

The finding suggests that the atmosphere of Mars behaves as a single system.

This finding might also explain why periodically Mars experiences a planet-wide dust storm, as it is doing right now.

July 17, 2018 Zimmerman/Batchelor podcast

July 17, 2018 9:48 pm Robert Zimmerman

Embedded below the fold in two parts. This podcast, entitled “Why does the US not have a manned spacecraft to orbit and to Mars?”, was a special broadcast, where the entire two segments were focused on outlining the delays NASA has forced on the private commercial crew companies, most especially SpaceX, in order to favor SLS as well as Boeing.

The first segment outlined the background. The second segment outlines solutions, central to which was the need to shut down SLS, Orion, and LOP-G now, before they do even more harm to the U.S.’s ability to compete effectively in space.

Whatever manned projects the federal government decides it must do, it must stop trying to ask NASA to build these projects. Instead, it must name a goal (building a base on the Moon, for example), and contract the requirements out to private companies. For the price of SLS we could launch between 300 and 400 Falcon Heavies, and do it NOW, repeatedly, rather than once four years hence. Nor is Falcon Heavy the only private option. Both Blue Origin and Northrop Grumman are building rockets that can supplement or even supplant SpaceX.

We should be relying on freedom and competition, the basic tenets of our country, not a Soviet-style top-down space program run by the government.

Professor calls for the defunding and shutting of America’s universities

July 17, 2018 5:18 pm Robert Zimmerman

Link here. Key quote:

When the term “Western civilization” is equated with racism, cultural superiority and pervasive oppression, and students in my political philosophy class refuse to study the works of John Stuart Mill or John Locke (or any other white thinker) because they consider them white supremacists, there is no lower level of educational hell. The manifest destiny of the humanities and social science professoriat is to have politicized knowledge supersede truth, objectivity, facts and genuine learning.

There are many social ills taking place in the academy, but the cultural relativists who rule its turf would abolish reason, rational argument, appeal to traditional canonical texts as evidence for objective truths about our world, and belief in an objective reality. Too often, they deride reason as a Eurocentric creation used to rationalize the existence of colonialism, slavery and genocide of native peoples.

Ordinarily, the best way to counter an intellectual adversary is through a contest of rational faculties. The person with reality on his or her side, with the best relevant facts and strongest arguments, usually wins. But today’s scholars in humanities and social sciences increasingly declare that modern argumentation is a white, Western form of domination and linguistic imperialism that silences racial and ethnic minorities and devalues their “lived experiences.”

One cannot argue with such people. The only alternative is to shut them down.

From his description of this new generation of students and the leftist teachers who now run American universities and are indoctrinating them I can only conclude that they are bigots filled with a hatred of all white people, and would prefer genocide to reasoned debate. Based on this, he is right. The funding to these teachers should cease, now.

A petition to kill SLS/Orion and LOP-G

July 17, 2018 12:54 pm Robert Zimmerman

Link here. To quote their announcement at the link:

What’s killing America’s human access to space? Three projects: a rocket called the Space Launch System, a capsule called the Orion, and a new project called the Lunar Orbital Platform-Gateway.

These three programs are political boondoggles, pork, pie in the sky, jobs programs disguised as space programs. The Space Launch System, for example, is touted as the biggest rocket ever built. But its $30 billion development cost is eating up almost all of NASA’s human budget for deep space. Compare that $30 billion with the cost of developing Elon Musk’s Falcon Heavy—less than a billion dollars. In other words, for the cost of developing the Space Launch System, we could develop thirty brand new rockets if we took the Elon Musk route. Or we could develop an entire Moon and Mars program.

After thirteen years of promises, the Space Launch System has never flown. And when it does, it will cripple NASA. The cost of one launch will be between one and two billion dollars. For that price, you could buy between eleven and 22 launches of the Falcon Heavy. You could buy the launches for an entire Moon and Mars program.

What’s worse, after the launch of each Space Launch System rocket, we will throw the exorbitantly-priced rocket away, then we will be forced to buy another one. Meanwhile, Elon Musk and Jeff Bezos are making rockets reusable. And reusable rockets, like reusable busses, trucks, trains, cars, and airplanes, will lower our cost of access to space dramatically.

Then there’s the Orion capsule that the SLS will fling into space. It cannot land. It can’t land on the Moon. It can’t land on Mars. And it’s too small to carry crews to Mars. It is a boondoggle.

Topping it all off is the Lunar Orbital Platform – Gateway, another nipple in the mouth of the Space Military Industrial Complex, another make-work program. It is a mini space station orbiting the moon. It’s useless and can’t even be manned or womanned year-round. But it will cost so much to build that we’ll never be able to build lunar landers. We won’t touch down on the moon. We’ll simply circle the moon from a distance and watch with frustration as the Chinese land human beings. [emphasis in original]

The last point about LOP-G is especially important. It is designed not to promote the exploration and settlement of the solar system, but as a kind of purgatory where the U.S. will remain trapped in lunar orbit, accomplishing nothing, while other nations land and settle the Moon.

I have signed. Anyone who has been reading Behind the Black or listening to me for the past decade will know that this has been my position, from the get-go. I am very glad that others in the space industry are now standing up to echo that position.

Curiosity's travels on and off Vera Rubin Ridge

For the overall context of Curiosity’s travels, see Pinpointing Curiosity’s location in Gale Crater.

In the almost two months since my May 23, 2018 update, a lot has happened, much of which I covered in daily updates. Curiosity found a good drill spot to once again test the new drilling techniques designed by engineers to bypass its stuck drill feed mechanism, and was successful in getting its first drill sample in about a year and a half. The rover then returned uphill, returning to a spot on Vera Rubin Ridge that, according to satellite data, has the highest signature for hematite on the entire ridge. The light green dotted line in the traverse map to the right shows the route Curiosity has taken back up onto Vera Rubin Ridge. The red dotted line shows the original planned route off the ridge and up Mount Sharp.

On the radio

Tonight I will have two radio appearances. First my normal twenty minute John Batchelor Show appearance will be structured somewhat differently. Instead of reviewing the space news for the past few days, we will be focused entirely on reviewing NASA’s seeming effort to slow commercial space down, so as to reduce the embarrassment to SLS as well as benefit Boeing.

The idea will be that we will make believe that I am giving a briefing to Mike Pence and the National Space Council, explaining in detail why NASA actually seems hostile to getting anything done. It is our hope that maybe someone in the administration might hear it, and rethink the Trump space policy.

Then, beginning at 7 pm (Pacific), I will be doing another live two hour appearance on The Space Show with David Livingston. I am sure the same subject will come up, along with other things. Feel free to call in to ask questions. David does not screen his calls, so this is your opportunity to ask me anything.

Astronomers discover 10 more Jupiter moons

July 17, 2018 9:48 am Robert Zimmerman

Worlds without end: Astronomers, while searching for objects in the Kuiper Belt, have discovered 10 more Jupiter moons.

All the newfound moons are small, between about 1 and 3 kilometres across. Seven of them travel in remote orbits more than 20 million kilometres away from Jupiter, and in the opposite direction from the planet’s rotation. That puts them in the category known as retrograde moons.

The eighth moon stands out because it travels in the same region of space as the retrograde moons, but in the opposite direction (that is, in the same direction as Jupiter’s spin). Its orbit is also tilted with respect to those of the retrograde moons. That means it could easily smash into the retrograde moons, pulverizing itself into oblivion. It may be the leftovers of a bigger cosmic collision in the past, Sheppard says.

Jupiter’s moons are named after gods with connections to the mythological Jupiter or Zeus. Sheppard has proposed naming the oddball Valetudo, after one of Jupiter’s descendants, the Roman goddess of hygiene and health.

The ninth and tenth newfound moons orbit closer to Jupiter, moving in the same direction as the planet.

I predict that these are not the last moons of Jupiter to be discovered. As our observing skills improve, more are certain to pop up.

Lockheed Martin key investor in Rocket Lab

July 17, 2018 9:39 am Robert Zimmerman

Capitalism in space: In this article about how Lockheed Martin and a smallsat rocket company have won launch development contracts from the British government in connection with the UK’s first spaceport in Scotland was this tidbit of information I have never known:

Lockheed Martin and Orbex, a UK-based company development a small satellite booster, have announced their intention to launch from Sutherland. Lockheed Martin will receive £23.5 million ($31.1 million) and Orbex will get £5.5 million ($7.3 million) from the U.K. Space Agency to advance work on their launcher programs.

The British government, Lockheed Martin and Orbex made their announcements at the Farnborough International Airshow.

Lockheed Martin is reportedly interested in launching a variant of Rocket Lab’s Electron booster from the Sutherland site. The U.S. aerospace contractor is a strategic investor in Rocket Lab, which already operates an orbital spaceport in New Zealand, and is planning to develop a U.S. launch pad for the Electron vehicle, which has made two test flights to date. [emphasis mine]

It sounds as if Lockheed Martin, after funding Rocket Lab and letting it do all the initial risky development, is now moving in to use its vast resources to develop its own competitive smallsat rocket, possibly using some of the knowledge gained by Rocket Lab.

India tests upgraded rocket engine

July 16, 2018 10:17 pm Robert Zimmerman

The new colonial movement: India’s space agency ISRO has successfully tested an upgraded version of the Vikas rocket engine it uses in its PSLV and GSLV rockets.

The test was conducted on Sunday, and validated the performance adequacy of Vikas Engine to be used in the upcoming second developmental flight of GSLV Mk-III

Vikas Engine, a workhorse liquid rocket engine designed by the Indian Space Research Organsiation (ISRO), powers the second stage of Polar Satellite Launch Vehicle (PSLV) of India. It also powers the second stage and the fourth strap of Geosynchronous Launch Vehicle (GSLV) and the twin-engine core liquid stage (L110) of GSLV Mk-III.

Essentially India here is doing what SpaceX did with its Merlin engine. Rather than start over with a new engine, they are upgrading it, a process that is faster and less expensive. And as they do it, they remain operational and competitive in the launch market, with as many as five launches now scheduled before the end of 2018.

ArianeGroup successfully tests solid rocket booster

July 16, 2018 10:11 pm Robert Zimmerman

Capitalism in space: ArianeGroup today successfully tested the solid rocket booster that it will use on both its Ariane 6 and Vega-C rockets in the 2020s.

The test success is good news for ArianeGroup, but this quote is actually more significant:

A compromise reached in May by European Space Agency members funding launch vehicle development will keep production of the P120C in Italy, allowing Avio to produce up to 35 boosters annually. A previous arrangement would have split production between Colleferro, Italy-based Avio and MT Aerospace of Augsburg, Germany.

The economies of scale provided by using the same booster for two rockets and concentrating production in one place are a key aspect of reducing the price for Ariane 6 missions by 40 to 50 percent compared to the Ariane 5 in use today.

Faced with stiff competition from SpaceX, the European Space Agency (ESA) gave ArianeGroup the power to structure operations more efficiently rather than cater to the pork desires of the agency’s many member nations.

Whether either Ariane 6 or Vega-C can compete with SpaceX’s reusuable rockets however remains doubtful. I expect that almost all of ArianeGroup’s customers in the next decade will be ESA member nations, required to buy its more expensive services.

A weird lunar lava field

July 16, 2018 2:43 pm Robert Zimmerman

Weird terrain at Ina on the Moon

Cool image time! The image on the right, reduced and rotated 180 degrees to post here, comes from a recent release for Lunar Reconnaissance Orbiter (LRO). It shows a flow of lava that partly covers an older terrain.

Some scientists propose that Ina formed as very young (less than 100 million years) volcanic eruptions because only a few larger impact craters (>20 m) have formed on its surface. Others believe it is quite ancient (3.5 billion years), possessing highly unusual physical properties that stifle the formation of normal impact craters. At least everybody agrees it was formed as basalt was erupted to the surface! But how and when Ina formed remains open.

Ina’s morphology is so unusual that it is easy to see inverted topography – that is, craters appear as bubbles rather than bowls! Think of Ina as a cast iron frying pan with freshly poured pancake batter; the wiggly textured material is the frying pan and the bulbous smoother mounds are the batter.

The image to the right has been rotated 180 degrees so that my mind at least can see it with the craters as bowls and the uplifted smooth lava as uplifted. If this doesn’t work for you, click on the link and look at the original image.

While some scientists think the lava flows are recent, no one knows at present the origins of the rougher terrain that the lava has partly obscured.
