Philae officially dead

10:23 pm

After another attempt to contact Rosetta’s lander Philae ended with no response, engineers now consider the spacecraft dead

“We did not hear anything,” says lander manager Stephan Ulamec. In the best-case scenario, Philae may have received the command and moved, but be unable to respond due to a damaged transmitter. It is more likely that the signal was not received. The team will try a few more commands, but it looks like Philae has officially gone. “We have to face reality, and chances get less and less every day as we are getting farther and farther away from the sun,” says Ulamec. “At some point we have to accept we will not get signals from Philae anymore.”

Cool image time! Be sure to click on this link to see the full resolution Cassini version of the image on the right. Its resolution is 10 miles per pixel, and even so the giant planet cannot be fit in the frame.

One moon, Tethys, is visible, though to make it so required its brightness to be increased by 2. Also, if you look close at the bands at the north pole you can see their strange still-not-understood pentagon shape.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Russians to develop Falcon 9-like rocket

9:21 am

The competition heats up: The Russian government has apparently given the go-ahead to the development of a Falcon 9-like modular rocket, original dubbed Soyuz 5 but now called Fenix (Phoenix).

The images at the link show it to be similar in concept to Falcon 9, with its first stage used as a component to produce multiple configurations. With one first stage it would resemble Falcon 9. In its Falcon Heavy configuration it would use three first stages strapped together. Moreover, the article notes that development would begin as expendable, but shift towards re-usability during operation, like Falcon 9. And it does appear that reducing cost is its main driver, since it will involve the development of only one engine and the reuse of it in every stage, like Falcon 9,

If all goes as outlined in the plan (don’t bet on it), the rocket would be operational by 2025, which is the one difference with Falcon 9. SpaceX got its rocket designed and launched in about five years. The Russian governmental system is going to take ten years to do the same..

The article is a detailed explanation of the rocket mentioned by Deputy Prime Minister Dmitri Rogozin during his confusing television briefing on December 30. The irony here is that, while this rocket might be able to compete with the Falcon 9 of 2016, when it becomes operational in 2025 who knows what will be considered competitive.

“If they can’t, turn into nonpaper w no identifying heading and send nonsecure.”

10:08 am

A new set of Hillary Clinton emails just released by the State Department includes one in which she is clearly ordering a subordinate to violate the law on how classified material should be transmitted.

Has the State Department released a smoking gun in the Hillary Clinton e-mail scandal? In a thread from June 2011, Hillary exchanges e-mails with Jake Sullivan, then her deputy chief of staff and now her campaign foreign-policy adviser, in which she impatiently waits for a set of talking points. When Sullivan tells her that the source is having trouble with the secure fax, Hillary then orders Sullivan to have the data stripped of its markings and sent through a non-secure channel.

Her exact written words are the title of this post.

More here. To me, it really doesn’t matter whether Hillary Clinton is ever indicted for what are clear violations of the law in how she handled classified material while she was Secretary of State. What matters is that we, as voters, have clear evidence now that she has contempt for the law, that she willingly and nonchalantly lies about it to the public, and that she is simply not a trustworthy individual. And this story is only one of many others about Hillary Clinton that all demonstrate the same things about her.

Lay-offs at Bigelow

9:35 am

The competition cools down? Bigelow Aerospace has laid off somewhere between 30 and 50 employees out of approximately 150 total employees.

In a Jan. 6 statement provided to SpaceNews, Bigelow Aerospace President Robert Bigelow said that the company determined that many areas of the company were “overstaffed” and decided to lay off employees to reduce the company’s expenses. “In December of 2015, we analyzed the amount of staff that we employed throughout all of our departments at Bigelow Aerospace, and discovered that numerous departments were overstaffed,” Bigelow said in the statement. “Regrettably, we had to make the choice that, beginning with the New Year, we need to follow standard business protocols, which sensibly requires an attempt to achieve balance in how much staff is necessary.”

The lay-offs do not necessarily indicate the company is failing, only that it is adjusting its payroll to the specific conditions of the moment. They have completed construction of their inflatable module for ISS and now only await its launch. Time to save money until they win their next contract.

Next Falcon 9 first stage will try to land on barge

9:30 am

The competition heats up: With its January 17 launch from Vandenberg, SpaceX will attempt to land the first stage on a barge in the Pacific.

This will also be the first attempt from the California launch site. If successful, it will give SpaceX greater flexibility on future first stage recoveries, as some launches won’t have the fuel to get the stage back to land but could bring it down on a barge at sea.

Mold on ISS plants

9:26 am

In December four of seven zinnia plants in a greenhouse on ISS became sickly or died because they were receiving too much water and developed mold.

The story doesn’t really tell us much, but this paragraph reveals I think some fundamental management problems in the way NASA is running the station:

ISS commander and NASA astronaut Scott Kelly reported the mold to Mission Control Dec. 22 just as Veggie principal investigator Trent Smith was trying to manage the water problem. In pictures, Smith saw water on the plants a few days before. He told Discovery News he was trying to relay a command from NASA’s station operations team to increase fan speed in Veggie, but the mold developed before the command could be put through. One solution was, on Christmas Eve, to designate Kelly “commander” of Veggie. Kelly now has more autonomy to make changes to Veggie’s conditions if he feels the plants need it.

The scientist noticed a problem but was unable to cut through the communications bureaucracy to talk to the astronauts so that changes could be made quickly. Meanwhile, the astronauts on board ISS had not been given the freedom to make common sense changes themselves. The result is that some of the plants died.

The solution, to give an astronaut more “autonomy”, is one that the Russians learned a long time ago on their Mir space station. It was also a lesson NASA learned even longer ago on Skylab. Moreover, when astronauts are finally flying interplanetary spaceships to the planets with greenhouses just like this, they will have to have that autonomy, no matter what rules NASA establishes. It seems amazing to me that NASA is still learning this lesson now.

One more thought: It is not really a problem that the scientist had trouble reaching the astronauts quickly. In fact, it probably indicates an area of management that NASA is handling well. Communications from the ground up to ISS can be a major problem, as everyone wants to talk to the astronauts and if NASA didn’t control that communications the astronauts would never have time to do anything. Thus, placing limits on that communications makes sense, though once again it also requires that the astronauts be given a great deal of freedom to make their own decisions, as they might not be able to talk to the right experts whenever necessary.

Betelgeuse baffles astronomers

9:10 am

The uncertainty of science: New data of the red giant star Betelgeuse says that the star simply doesn’t have the energy to eject the large amount of gas it routinely blows into space.

“[W]e now have a problem”, says Graham Harper, an astrophysicist at the University of Colorado Boulder. “If you’re going to eject matter you have to put energy in, and we’re not seeing that.” Harper and his colleagues used the US–German Stratospheric Observatory for Infrared Astronomy (SOFIA), a 2.5-metre telescope that flies in a modified Boeing 747 aeroplane, to take Betelgeuse’s temperature. They found that the star’s upper atmosphere was much cooler than expected — so cool, in fact, that it doesn’t seem to have enough energy to kick gas out of its gravitational pull and into space.

“This challenges all our theoretical models,” Harper said on 7 January at a meeting of the American Astronomical Society in Kissimmee, Florida. [emphasis mine]

The data suggests the temperature of the ejected gas to be only about 512 degrees Fahrenheit. This is far too cool to fit any theory for explaining the vast amounts of gas that the star routinely puffs into space. It also suggests, not surprisingly, that scientists do not yet have a enough information to develop a clear understanding of stellar evolution. They have enough information to form rough theories, but there is still much too much they do not know.

One last chance for Philae

8:56 am

With time running out as Comet 67P/C-G moves away from the Sun, the Rosetta engineering team is going to try one more time to contact the lander Philae.

The lander team are going to try another method to trigger a reponse from Philae: on 10 January they will send a command, via Rosetta, to attempt to make Philae’s momentum wheel switch on. “Time is running out, so we want to explore all possibilities,” says Stephan Ulamec, Philae lander manager at DLR. Philae’s momentum wheel ensured that it was stable during its descent from the orbiter on 12 November, 2014.

If the command is successfully received and executed, the hope is that it might shift the lander’s position.”At best, the spacecraft might shake dust from its solar panels and better align itself with the Sun,” explains Philae technical manager Koen Geurts at DLR’s lander control centre.

They also believe that one of the lander’s two transmitters and one of its two receivers are broken, which makes communications difficult at best.

Sunspot decline continues

12:06 pm

NOAA’s monthly update of the solar cycle, showing the Sun’s sunspot activity in December, was posted earlier this week, and I am posting it here, as I do every month, with annotations to give it context.

The decline in sunspots continues, tracking closely the rate of decline predicted by the 2007 and 2009 predictions (the lower green curve and the red curve) but the overall solar maximum has been far shorter and less powerful than predicted.

How to really look for aliens

11:38 am

Two scientists summarize the challenge for finding alien life in the universe.

Look for high amounts of oxygen and mid-infrared energy, the second of which has already produced some candidates.

A recent large survey by the Wide-field Infrared Survey Explorer (WISE) satellite did identify five red spiral galaxies whose combination of high MIR and low near-ultraviolet luminosities are inconsistent with simple expectations from high rates of star formation. A conventional explanation for these observations, such as the presence of large amounts of internal dust, has not been ruled out, however. Such peculiar objects deserve follow-up observations before we explore whether they might represent the signatures of galaxy-dominating species.

The article is very thoughtful, however, and outlines in detail the issues and problems the research faces. We might, in a few decades, have the capability to answer this question, but then, the aliens might be alien enough to still be undetectable. Or they might not exist at all.

Arianespace sales top SpaceX in 2015

10:14 am

The competition heats up: According to Arianespace’s CEO Stephane Israel, the company signed more new launch contracts in 2015 than SpaceX, despite their competitor’s much larger PR footprint.

At a briefing here outlining Evry, France-based Arianespace 2015 record and plans for 2016, Israel sought to portray Arianespace as once again in the driver’s seat when it comes to commercial launches. After drawing even with Hawthorne, California-based SpaceX in 2014, with nine commercial orders each, Arianespace’s count for 2015 showed its Ariane 5 rocket winning 14 contracts for geostationary-orbit satellites, compared to nine for SpaceX and one each for International Launch Services of Reston, Virginia, which markets Russia’s Proton; and for the Atlas 5 rocket of United Launch Alliance of Centennial, Colorado.

Arianespace’s count includes one undisclosed customer. Unless it’s identified, it will not be included in SpaceNews’s annual count of firm contract awards. Of the 13 satellites remaining, two are for Europe’s meteorological satellite organization, Eumetsat, and cannot be considered commercial wins. In addition to the geostationary-satellite contracts, Arianespace in 2015 booked the largest single launch contract, to use 21 Russian Soyuz rockets — including the Europeanized version operated from Europe’s spaceport — to launch the OneWeb low-orbiting broadband constellation.

Israel also spent a lot of time at the briefing dealing with reporters’ questions about SpaceX, where he poo-pooed the significance of the Falcon 9 first stage landing, noting repeatedly the accepted wisdom that the stress of launch limits the re-usability of rocket stages. This suggests that Arianespace’s next generation rocket, Ariane 6, is not likely to have this capability. Considering that its launch price is now estimated to be between $90 and $100 million, I wonder how they will compete with a reusable Falcon 9 that will likely cost a third this price.

That the Russians only signed one new contract for its Proton last year, as noted in the quote above, also tells us that SpaceX is getting most of its market share from the Russians. If the company should continue to lower its costs and increase its launch rate over time, they will then start stealing market share from others. Thus, Arianespace’s CEO makes a very big mistake if he takes their competitive threat lightly.

Starliner schedule shapes up

9:49 am

The competition heats up: The schedule and launch plans for Boeing’s manned Starliner spacecraft are now becoming solidified.

For Boeing, Starliner will first launch on an uncrewed test flight to the Station via the “Boe-OFT” mission in April or May, 2017 – on a 30 day mission, ending with a parachute-assisted return. Should all go to plan, the second mission will involve a crew on a mission designated “Boe-CFT”, launching sometime between July and September, 2017, on a 14-day mission to the ISS.

The article also outlines the launch procedures Boeing intends to follow, some determined by the company and some by NASA’s complex safety rules. One interesting tidbit about Starliner revealed here that I was unaware of previously is that the capsule is made of separate top and bottom units that are only fitted together late in the launch process, allowing for easier access.

Rubio as establishment proves tea party won

9:49 am

David French notes that if Marco Rubio is now considered a RINO establishment candidate whom conservatives must oppose it demonstrates beyond doubt that the tea party has won the debate.

It seems that [Rubio’s] now the “establishment” candidate mainly because a number of establishment figures and donors have defected to him after their preferred candidate — perhaps Bush, Christie, or Kasich — failed to gain traction. But if the standard for establishment status is simply whether establishment figures have chosen to support you after their first-choice candidate fails, then every single GOP contender is either establishment or establishment-in-waiting. After all, if Rubio falters, mass numbers of establishment politicians and donors will rush to back Cruz over Trump. And if Cruz falters, those same people will presumably back Trump over Hillary.

Here’s the reality: In the battle — launched in 2010 — between the tea party and traditional GOP powers, the tea party largely won. The contest between Rubio, Cruz, and Trump is a fight between Tea Party 1.0, Tea Party 2.0, and classic American populism. And each one of these candidates would need traditional Republican or “establishment” support in the general election.

He’s right. The political debate is now being fought entirely on tea party terms, with those terms forcing the candidates consistently rightward on every issue. Not only is this a good thing, it suggests a major shift by the American public itself. Our so-called “intellectual elites” might still be liberal, standing there with their fingers in their ears and eyes closed chanting “La-la-la-la-la-la-la-LA!!” so they won’t get triggered by new ideas, but the public has heard what tea party advocates have said and has found those positions worth supporting.

This suggests to me that we might even be seeing a shift in the voting patterns of the low-information television voter, the kind of voter who only comes out during Presidential elections and routinely supports the Democratic candidate being pushed by the mainstream networks. If so, the Democratic Party is in very deep trouble, as they continue to behave as if their low-information voting block remains solid and under their control.

Europe might end its ISS partnership in 2020

9:26 am

Despite agreements by Russia, Canada, and Japan to extend their ISS partnership with the U.S. through 2024, both France and Germany of the European Space Agency (ESA) are having second thoughts and might pull out in 2020 instead.

In separate statements Jan. 4 and Jan. 5, the heads of the French and German space agencies said a detailed study is under way to assess the future operating cost of the station, and whether the cost can be justified given the pressure on near-term budgets.

Pascale Ehrenfreund, chairman of the board of the German Aerospace Center, DLR, which is Germany’s space agency, said DLR would make no promises until after a full review of ISS’s value. “In view of the high cost involved and the resulting implications on budgets of [European Space Agency] member states, we have to evaluate very carefully costs and benefits of a continued participation in the ISS,” Ehrenfreund said in a Jan. 5 statement in response to SpaceNews inquiries. “It’s only based on this evaluation that we will be able to take a definite position.”

Germany has been Europe’s ISS champion — its biggest paymaster and most vocal booster — for more than 20 years and at times has had to strong-arm France into boosting its support under threat of reduced German backing of Europe’s Ariane rocket program, a French priority.

Eventually, all the partners running ISS with the U.S. are going to come to this decision, which means the U.S. government should begin thinking about what it does at that time. I say, when that time comes the government will privatize the station, giving it to the private companies best able to make a profit from it. And by 2024 the U.S. is likely to have a number of companies quite capable of doing so, from SpaceX to Blue Origin to Bigelow.

There also will be no reason to destroy the station at that time. Being modular, much of it is relatively new, and what is old could be replaced with relatively simplicity. This is a national asset that should not be abandoned nonchalantly.

Hillary Clinton vows to investigate UFOs if elected

8:55 am

Well, we now know her priorities! In a meeting with the editorial board of a New Hampshire newspaper, Democratic presidential candidate Hillary Clinton vowed to find out once and for all whether UFOs have been discovered by the federal government and kept secret.

Her husband Bill Clinton apparently tried and failed to uncover those buried records while he was President.

I am sure this reassures you all. While the Republicans are distracted by unimportant issues, such as terrorism, radical Islam, a weak economy, an out-of-control federal budget, and a corrupt federal bureaucracy that is abusing its power while failing to do its job, Hillary Clinton has her sights on issues of real importance.

2015 the busiest launch year for Florida since 2003

8:46 am

The competition heats up: With 17, Florida had more rocket launches in 2015 than it has had in more than a dozen years.

Russia once again had the most launches in the year, with 29 (including 3 failures). Overall, launches worldwide were down, from 92 in 2014 to 87 in 2015. However, the uptick in the U.S., spurred I think by SpaceX, suggests that the U.S. numbers will continue to rise, and in in a few years the U.S.will take the lead.

Note also that when the shuttle was retired many thought that — with the loss of that government operation — it would be the end of the Florida launch business. Competition and private enterprise have instead shown that a dependence on government is not the only way to do things, and is in fact not the best way to do things.

Four elements added to periodic table

8:30 am

Scientists have now officially added four new elements to the periodic table, completing the discovery of all elements through 118.

All of the elements were created in the lab, by smashing lighter atomic nuclei together. The unstable agglomerations of protons and neutrons last mere fractions of a second before they fall apart into smaller, more stable fragments.

The teams that have been given credit for the discoveries can now put forward proposals for the elements’ names and two-letter symbols. Elements can be named after one of their chemical or physical properties, a mythological concept, a mineral, a place or country, or a scientist. Priority for discovering element 113 went to researchers in Japan, who are particularly delighted because it will become the first artificial element to be named in East Asia. When the element was first sighted 12 years ago, ‘Japonium’ was suggested as a name.

While creating element 119 is believed possible, beyond that it is thought unlikely that anything heavier can be produced in the lab.

Millions opt out of Obamacare despite penalities

8:48 am

Finding out what’s in it: The White House last month admitted that millions of healthy Americans have decided it is cheaper to pay the Obamacare penalty for not having health insurance than pay for insurance that is too expensive and does them little good.

Because so many young and healthy people are doing the math and refusing to pay for a product they don’t need and costs them far more than it is worth, the insurance pool is, as predicted, increasingly made up of sick people only. Such a pool is not viable for the insurance companies, and guarantees that they will eventually go bankrupt.

But hey, Obama and the Democrats promised us all that Obamacare would lower costs and make everyone happy. They wouldn’t lie to us, would they?

A detailed look at Trump’s positions

8:45 am

This link provides a very detailed but thorough summary of the political positions that Donald Trump has taken in the past year during his presidential campaign. Take a look, as it does a nice job of listing his stance on almost all the important issues that appear to concern Americans at this time. His conclusion is telling:

Except for immigration, foreign policy, and energy, all of Trump’s contemporary positions are more identifiable with liberal positions, which is not surprising, considering he has spent most of his life as a liberal Democrat. Now, if you’re a conservative and immigration is your number-one issue, you can still justify a vote for Donald Trump. But Ted Cruz is almost as good – promising to build a wall, oppose amnesty, and enforce the law – and he’s much better on just about every other issue.
