China releases images from lunar rover and lander

February 4, 2016 10:33 am Robert Zimmerman

Yutu on the Moon

China has made available a new batch of very cool images taken by its Chang’e 3 lander and Yutu rover, and Emily Lakdawalla at the Planetary Society has figured out how to view them.

In a recent guest blog post, Quanzhi Ye pointed to the Chinese version of the Planetary Data System, and shared the great news that Chang’e 3 lander data are now public. The website is a little bit difficult to use, but last week I managed to download all of the data from two of the cameras — a total of 35 Gigabytes of data! — and I’ve spent the subsequent week figuring out what’s there and how to handle it.

So, space fans, without further ado, here, for the first time in a format easily accessible to the public, are hundreds and hundreds of science-quality images from the Chang’e 3 lander and Yutu rover. I don’t usually host entire data sets (PDS-formatted and all) but I made an exception in this case because the Chinese website is a bit challenging to use.

The image above is a cropped version of Yutu, taken by the lander. Be sure and go to the link to see the full image as well as others.

Curiosity moves on, scoop still not working

February 4, 2016 10:10 am Robert Zimmerman

Curiosity’s science team has finished its work at Namib Dune and has decided to move on, even though they are still analyzing an unspecified issue with the rover’s scoop instrument.

So far, in the week since they first had a problem while sifting sand from the dune, they have not described in any way what the problem is. All they have said is this:

Unfortunately, the CHIMRA behaved in an unexpected way during processing of the third scoop on Sol 1231, which prevented completion of the arm activities planned for last weekend.

The robot arm functions, and they used it yesterday to get some extreme close-ups of the sand, but it appears they cannot use the scoop at this time.

A look inside Comet 67P/C-G

February 4, 2016 9:53 am Robert Zimmerman

The Rosetta science team has determined that Comet 67P/C-G has no voids or large caverns in its interior, and that its low density is because its dust and water ice have mixed to produce a “fluffy” density.

In a new study, published in this week’s issue of the journal Nature, a team led by Martin Pätzold, from Rheinische Institut für Umweltforschung an der Universität zu Köln, Germany, have shown that Comet 67P/Churyumov-Gerasimenko is also a low-density object, but they have also been able to rule out a cavernous interior. This result is consistent with earlier results from Rosetta’s CONSERT radar experiment showing that the double-lobed comet’s ‘head’ is fairly homogenous on spatial scales of a few tens of metres.

The most reasonable explanation then is that the comet’s porosity must be an intrinsic property of dust particles mixed with the ice that make up the interior. In fact, earlier spacecraft measurements had shown that comet dust is typically not a compacted solid, but rather a ‘fluffy’ aggregate, giving the dust particles high porosity and low density, and Rosetta’s COSIMA and GIADA instruments have shown that the same kinds of dust grains are also found at 67P/Churyumov-Gerasimenko.

Falcon 9 to be modified

February 4, 2016 9:44 am Robert Zimmerman

The competition heats up: SpaceX is modifying its Falcon 9 rocket based on engine tests it performed on the December 22 returned first stage.

SpaceX will be making modifications to its Falcon 9 rocket based on what the company learned from re-igniting the engines on the vehicle it landed. That’s according to SpaceX president Gwynne Shotwell, who spoke about the state of the company today at the Commercial Space Transportation Conference in Wasington, DC. Shotwell didn’t specify what those modifications will be, but said the changes will make the vehicle “even more robust” for its ascent into space.

This report helps explain why SpaceX has pushed back all planned launches of the upgraded Falcon 9 rocket. Their tests of the returned first stage revealed issues that they think are important enough to be addressed before another rocket is launched, and they are proceeding to deal with those issues.

It also illustrates an enormous advantage they have over every other rocket company that has ever existed in the past. They, unlike all past rocket companies, actually have a used first stage that they can study to see the real consequences of launch and landing. All previous estimates of those consequences were only based on computer models and speculation.

Below the fold is Tuesday’s podcast of my appearance on the John Batchelor show. In addition to discussing Falcon Heavy, Ariane 6, and the question of rocket re-usability, I also lambasted the glacially slow pace of NASA’s Orion project, producing four capsules for a mere $17 billion in only 19 years! And speaking of glaciers, I also noted in the science segment the stonewalling at NOAA that prevents scientists from analyzing the rational behind their “adjustments” to their climate data, all of which cool the past and warm the present.

Carter would pick Trump if he had no other choice

February 3, 2016 4:26 pm Robert Zimmerman

Heh: When asked by a reporter about the Presidential campaign, former President Jimmy Carter said he’d pick Donald Trump over Ted Cruz if they were his only choices. And why would he do that?

If he had to choose between Cruz and Trump for the Republican nomination, Carter chuckled, “I think I would choose Trump, which may surprise some of you.” (It did, judging by the loud laughter from the audience.)

“The reason is, Trump has proven already he’s completely malleable,” Carter explained. [emphasis mine]

I think this might one of those very rare moments when Jimmy Carter has correctly analyzed the situation.

Luxembourg to establish space property rights

February 3, 2016 10:34 am Robert Zimmerman

The competition heats up: The government of Luxembourg today announced an initiative to establish a legal framework that will ensure property rights in space for private investors.

The Luxembourg Government announced a series of measures to position Luxembourg as a European hub in the exploration and use of space resources. Amongst the key steps undertaken, as part of the spaceresources.lu initiative, will be the development of a legal and regulatory framework confirming certainty about the future ownership of minerals extracted in space from Near Earth Objects (NEO’s) such as asteroids.

Luxembourg is the first European country to announce its intention to set out a formal legal framework which ensures that private operators working in space can be confident about their rights to the resources they extract, i.e. rare minerals from asteroids. Such a legal framework will be worked out in full consideration of international law. Luxembourg is eager to engage with other countries on this matter within a multilateral framework.

The announcement is a bit vague about what exactly Luxembourg really plans to do. For example, it is unclear if this framework will only apply to Luxembourg citizens, or will be used to bring the private efforts from other countries to Luxembourg (the more likely scenario). It also does not tell us how the initiative will deal with the UN Outer Space Treaty, which essentially outlaws countries from establishing their own legal framework in space. Individuals can supposedly own private property in space under that treaty, but no country can claim territory or impose its own legal framework on any territory, thus making any private property claims unclear and weak.

North Korea announces planned satellite launch

February 3, 2016 10:19 am Robert Zimmerman

North Korea today revealed plans to place a satellite in non-geosynchronous orbit sometime in the next two weeks.

News of the planned launch between Feb. 8 and Feb. 25 drew fresh U.S. calls for tougher U.N. sanctions already under discussion in response to North Korea’s nuclear test. State Department spokesman John Kirby said the United Nations needed to “send the North Koreans a swift, firm message.”

Pyongyang has said it has a sovereign right to pursue a space programme by launching rockets, although the United States and other governments worry that such launches are missile tests in disguise.

It is horrifyingly hilarious to read the bluster put forth by Obama administration officials about this new North Korean effort to develop ICBMs that, as the article says, “could reach the U.S. West Coast.” Besides wanting to send “a swift, firm message,” they call the North Korean launch announcement a “slap in the face”, “another destabilizing provocation,” and “an egregious violation.” They then say they are working “cooperatively and effectively with the Chinese to counter this threat.”

It is laughable, but terrifying at the same time. North Korea, led by the worst kind of power-mad tyrant, is developing the ability to launch nuclear weapons to any place on Earth, and all our leaders can do is whine how mean they are.

National debt tops $19 trillion

February 3, 2016 12:37 am Robert Zimmerman

The coming dark age: The national debt has hit $19 trillion, and the increase from $18 trillion was the fastest on record.

It took a little more than 13 months for the debt to climb by $1 trillion. The national debt hit $18 trillion on Dec. 15, 2014. That’s a slightly stepped-up pace compared to the last few $1 trillion mileposts. It took about 14 months for the debt to climb from $17 trillion to $18 trillion, and about the same amount of time to go from $16 trillion to $17 trillion.

The facts here also illustrate the complete failure of the Republican leadership to do what they promised when the voters gave them control of Congress.

But increasingly, Congress has instead allowed more borrowing by suspending the debt ceiling for long periods of time. That allows the government to borrow any amount it needs until the suspension period ends. Back in November, the debt ceiling was suspended again, after having been frozen at $18.1 trillion for several months. As soon as it was suspended, months of pent-up borrowing demand by the government led to a $339 billion jump in the national debt in a single day.

Under current law, the debt ceiling is suspended until March, 2017, meaning the government can borrow without limit until then. Obama is expected to leave office with a total national debt of nearly $20 trillion by the time he leaves office.

It was the Republican leadership that suspended the debt ceiling and allowed spending to rise so fast. This is also the reason that their favorite candidates for President, led by Jeb Bush, have done so poorly, and why the outsiders (Trump and Carson) and the new generation of tea party politicians (Cruz and Rubio) dominated the Iowa caucuses. And I expect that domination to continue in New Hampshire, South Carolina, and beyond.

New Shepard launch update

February 2, 2016 10:49 pm Robert Zimmerman

The competition heats up: Blue Origin expects to do about one launch per month of its New Shepard rocket in the next two years leading up to commercial space tourism flights in 2018.

Reports from the meeting quoted [Blue Origin executive Brett] Alexander as saying there would be a couple of dozen such test flights over the course of the next two years – which works out to an average of one flight per month. Alexander also told the gathering that it’s still too early to announce the ticket price for passenger flights.

First SLS launch will carry 13 cubesats

February 2, 2016 10:42 pm Robert Zimmerman

NASA today announced that the first test flight of its giant SLS rocket, more powerful than the Saturn 5 and intended to make human missions beyond Earth orbit possible, will carry 13 cubesats in addition to its Orion capsule.

Because the mission plans on sending the unmanned Orion on an Earth orbit beyond the Moon, these cubesats will have an opportunity to go where no cubesat has gone before.

The candidates’ take on science

February 2, 2016 9:30 am Robert Zimmerman

The journal Science today posted this somewhat useful review of the positions that the presidential candidates have taken on a variety of science issues.

One must read this article while recognizing that Science is not trustworthy on many of these subjects. For one, its position is always for more funding. If a politician even suggests that the rate of budget increases should be trimmed, Science will frame that suggestion as if the politician wants to slash all spending for science.

For another, Science is quite biased and agenda-driven when it comes to climate change, and illustrates that bias in this article in its reporting on Ted Cruz (R-Texas) and his position on this subject. To quote:

Cruz has used his position as head of a Senate subcommittee that oversees climate research to question recent temperature trends. Last fall Cruz called climate change a “religion.” Voted no on a measure affirming that humans contribute to climate change. [emphasis mine]

The highlighted words above is a misstatement of what Cruz has said and serves to trivialize his position. He hasn’t questioned the “temperature trends”, which for almost two decades have been stalled. If anything, he has noted these trends as evidence that the theory of human-caused global warming has a problem. What he has questioned is the data that NOAA and NASA have been publishing. If anything, Cruz’s positions on the science of climate change have indicated that he has educated himself well on the subject, and has taken some thoughtful positions on it.

Nonetheless, this article is worth reviewing, as it reveals a great deal about the candidates. A close look for example at Rubio’s position on climate change reveals that he might not be consistent, and that his stated positions now might not match what he does should he become president.

NASA ships a capsule

February 2, 2016 9:10 am Robert Zimmerman

In what appears to me to be a overwrought attempt to make the minor shipment of one Orion capsule appear to be a major achievement, NASA on Monday transported the next Orion capsule from Louisiana to Florida.

They used the NASA’s Super Guppy cargo plane to do it, even though I suspect that the capsule really isn’t that large and could have likely been shipped by road in a truck for a lot less. The agency also apparently made a big deal about this shipment with the press, which like sheep went along with it.

The pictures here illustrate what I mean. I grant that the Super Guppy is a cool plane, and it is certainly fun to see how it is loaded and flies, but from a cost perspective this seems to be a very expensive way to transport the capsule.

As a result, the impression this all leaves me with is that NASA is really not doing very much with Orion, working at a snail’s pace to stretch out the payments, and thus has to sell every little thing to convince the public that this project is accomplishing a lot.

Iowa results suggest strong Cruz future

February 1, 2016 10:18 pm Robert Zimmerman

Ted Cruz’s strong win in the Iowa caucuses tonight, combined with a record turnout of Republican voters (180K+) indicates that his support is far deeper than any poll or expert had predicted. Every prediction had insisted that if the turnout was big, Donald Trump would win. As noted at the second link, “By Team Cruz’s own admission, turnout of 175,000 tonight would strongly favor a Trump win.”.

Instead, the turnout was 180,000, and Trump lost to Cruz handily and was almost beaten by Marco Rubio.

On the other side of the aisle Clinton appears to have barely squeaked by Sanders. To me the more significant number is that the Democrats could only marshal about 10,000 voters, far less than in the past and suggesting that the enthusiasm for either of their candidates is weak.

A look at the emerging dark age in California

February 1, 2016 10:20 am Robert Zimmerman

The coming dark age: Victor Davis Hanson took a journey through California recently and what he learned he found quite depressing.

The state bears little to no resemblance to what I was born into. In a word, it is now a medieval place of lords and peasants—and few in between. Or rather, as I gazed out on the California Aqueduct, the Golden Gate Bridge and the San Luis Reservoir, I realized we are like the hapless, squatter Greeks of the Dark Ages, who could not figure out who those mythical Mycenaean lords were that built huge projects still standing in their midst, long after Lord Ajax and King Odysseus disappeared into exaggeration and myth. Henry Huntington built the entire Big Creek Hydroelectric Project in the time it took our generation to go to three hearings on a proposed dam.

His analysis is cogent and worth a careful read. I think the most depressing point he makes is how the priorities of liberal elites of California have no connection with the real needs of the general population, and are thus causing the quality of life for those without gobs of money to decline precipitously.

Stranger still, the infusion of hundreds of billions of global tech capital created a new, politically active, multimillionaire elite, completely insulated from the consequences of their own therapeutic ideologies. The reason why California’s gas and electricity prices are among the highest in the nation, why its income, sales and gas taxes are likewise among the steepest, and why the price of housing per square foot soars over $1,000 while nearby tens of thousands of acres of open ground sit sacrosanct—essential open viewing space for those who can afford $1.5 million, 1,500 sq. feet 1970s houses—is this new rich elite.

California is No Place for the Middle Class

Easy money translated into a utopian view of living. Higher taxes were a small price to pay for the psychological reassurance that a millionaire was still liberal. Professions of abstract progressive piety make guilt-free grasping materialism possible. I suppose if you make $800,000, having your legislature outlaw dogs chasing bears and bobcats instead of building a reservoir makes you feel as if you make $80,000.

We are seeing this pattern repeat everywhere across the country. We are even seeing it repeat in Europe, with the ordinary citizens finding their lives destroyed by Islamic immigrants forced on them by pie-in-the-sky elite elected officials.

The last link is very illuminating. It shows a German townhall meeting where an elected mayor tells his citizens that rather than stop the physical abuse of women by Muslim immigrants the women should run and hide. The crowd understandably reacts in horror and indignation. Whether they will move to replace this mayor and his ilk remains an unknown. In the U.S. too many Americans remain willing to accept the rule of similar elitists, which is why we still have a viable Democratic Party.

Another 5 month slip of first Falcon Heavy launch

February 1, 2016 9:46 am Robert Zimmerman

In the heat of competition: Amid a slew of SpaceX launch delays in the past month due to the introduction of an upgraded Falcon 9, Elon Musk noted at a student event in Texas on Sunday that the first demo launch of the Falcon Heavy is likely to happen in September, not April as previously announced.

The article is mostly focused on the launch delays of the Falcon 9, which for some of SpaceX’s customers are becoming a financial problem. The company is obviously trying to make sure that further Falcon 9 launches are a success, but the unreliability of its schedule is clearly a reason satellite companies like Eutelsat have signed new contracts with Russia’s ILS or Arianespace. Even with the problems Russia has had with its Proton they have managed a more reliable launch schedule.

Then again, the Proton and Ariane 5 have been around for decades. Their companies aren’t trying to improve them in any way. The delays in SpaceX’s schedule are somewhat understandable in this context. Better to launch slowly with new designs then to have a failure that entirely stops things for months.

Nonetheless, it might be wise for SpaceX to settle on the present Falcon 9 design for awhile, so that they can catch up and make their customers happy. Moreover, the further delay of the Falcon Heavy launch is definitely disappointing.

An issue with Curiosity’s scoop

January 30, 2016 10:35 pm Robert Zimmerman

The unit at the end of Curiosity’s robot arm that scoops up sand and processes it through sieves experienced “an anomaly” on January 25, causing a halt in arm operations.

The instrument has been scooping up sand from the sand dune that the rover has been studying recently. So far there has been no details at all about the “anomaly”, so it is unclear how serious the problem is. In the meantime the rover has been using its cameras and other instruments to do other observations.

Russian Proton rocket successfully launches commercial satellite

January 30, 2016 10:21 pm Robert Zimmerman

The competition heats up: The Russians successfully put a European commercial communications satellite into orbit today their Proton rocket.

It was the sixth successful Proton launch since their May failure. The key quote from the article however was this:

ILS owner Khrunichev State Research and Production Space Center of Moscow has said it would give ILS leeway to reduce prices to work its way back into the regular commercial-launch rotation alongside SpaceX and Europe’s Arianespace. The decline of the Russian ruble against the U.S. dollar has made that task easier as most commercial launch contracts are priced in dollars.

In other words they are going to cut prices to compete, and the falling ruble has given them more leeway to do it.

Water ice on Pluto’s surface

January 29, 2016 1:33 pm Robert Zimmerman

The uncertainty of science: An analysis of data from New Horizons suggests that water ice is more widespread on Pluto’s surface than previously believed.

The new map shows exposed water ice to be considerably more widespread across Pluto’s surface than was previously known — an important discovery. But despite its much greater sensitivity, the map still shows little or no water ice in the informally named places called Sputnik Planum (the left or western region of Pluto’s “heart”) and Lowell Regio (far north on the encounter hemisphere). This indicates that at least in these regions, Pluto’s icy bedrock is well hidden beneath a thick blanket of other ices such as methane, nitrogen and carbon monoxide.

As the press release notes, water ice is actually “Pluto’s crustal ‘bedrock'”, so there really is plenty there. It is just buried below a surface of methane, nitrogen, and carbon monoxide “topsoil”.

300 climate scientists demand NOAA explain its global warming climate data

January 29, 2016 9:32 am Robert Zimmerman

No settled science here: Three hundred climate scientists have signed a letter demanding that NOAA stop stonewalling the Congressioinal investigation of the agency’s repeated adjustments to raw climate data so that the record shows increased warming, when there is none.

Of the 300 letter signers, 150 had doctorates in a related field. Signers also included: 25 climate or atmospheric scientists, 23 geologists, 18 meteorologists, 51 engineers, 74 physicists, 20 chemists and 12 economists. Additionally, one signer was a Nobel Prize winning physicist and two were astronauts.

Seems to me that this letter and the number of climate scientists willing to sign it alone demonstrates that the “97 percent consensus” on global warming is bogus. As for NOAA, the agency is legally in violation of the law by refusing to provide information requested by Congress. Moreover, what are they afraid of? If they haven’t been tampering with the data improperly, they should have no reason to resist the congressional investigation. That they are stonewalling it suggests that they are hiding something. It also suggests that they haven’t the faintest idea what the scientific method is, which requires total transparency so that others can check the results and make sure they are correct.

Average Obamacare premiums are unaffordable

January 29, 2016 9:11 am Robert Zimmerman

Finding out what’s in it: Independent studies have found that the average cost for health insurance under Obamacare in 2016 will be about $300 a month for the program’s silver plan.

That’s not the biggest problem, according to analysts. For many, their health insurance has dramatically changed under Obamacare. Deductibles and out of pocket expenses are higher, so many of their medical expenses are no longer covered. Some consumers who say they had good, affordable plans prior to the Affordable Care Act say they can no longer afford the new plans, which are substandard in terms of what they cover.

Obviously, this means the voters should throw their support to the Democratic Party and any one of their presidential candidates, all of whom have promised to fix this disaster of a law with even more government-imposed rules.

Europe settles on Ariane 6 design

January 28, 2016 6:47 pm Robert Zimmerman

The competition heats up? Airbus Safran and the European Space Agency have settled on the design of their next generation rocket, Ariane 6.

It will not be re-usable, and though they say it will be 40-50% cheaper to produce than Ariane 5, it is very clear from the quotes in the article that they are instead depending on trade restrictions to maintain their European customers, even if it costs them a lot more to put satellites in orbit.

For its part, Airbus Safran does not envisage making Ariane 6 recoverable, not in the short term. Mr Charmeau [the company’s CEO] believes that different market conditions apply in Europe and the US, which means there will not be a single, winner-takes-all approach. He cites, for example, the restricted procurement that exists in all major political blocs, which essentially bars foreign rockets from launching home institutional and government satellites. Nowhere is this more true than in the US, but in Europe too there is an “unwritten rule” that European states should use European rockets.

From an American perspective this lazy attitude is fine with me. Let American companies compete aggressively. They will then leave the Europeans and everyone else in the dust.

Using Roman tactics to quell riots

An evening pause: The following was a drill by South Korean police to practice the techniques they use to control demonstrations and riots. Anyone who knows anything about Roman military tactics will instantly recognize what they are doing.

While this is not a real world situation, in an actual riot these techniques are certainly going to be effective. They also illustrate who is the civilized side in these disturbances.
