Russia announces revised launch schedule for ISS

10:11 pm

As promised, the Russians today revealed their revised schedule of launches for ISS for the next few months.

The next manned launch will be on July 3, and though it will use a Soyuz rocket, it will not use the upgraded rocket version that had a conflict with its Progress freighter during the April launch. They have still not described what that conflict was, or how they plan to fix it on future launches.

Meanwhile, a Soyuz capsule docked to ISS suddenly fired its thrusters unexpectedly during testing of the station’s radio system. The burn changed the station’s orientation, which required other thrusters to compensate.

Did some dinosaur soft tissues survive fossilization?

2:36 pm

The uncertainty of science: New research strongly suggests that within dinosaur fossils are found many preserved soft tissues from when the creature was still living.

As early as the 1970s, researchers captured images of what looked like cellular structures inside dinosaur fossils. But did the structures contain actual tissue? Proteins commonly decay hundreds to thousands of years after an organism dies, but in rare cases they have been known to survive up to 3 million years. In a series of studies beginning a decade ago, a team led by North Carolina State University paleontologist Mary Schweitzer reported that they had extracted what appeared to be collagen, the most abundant protein in bone, from a 68-million-year-old T. rex fossil. They sequenced fragments of the protein and concluded that it closely matched that of birds, dinosaurs’ living descendants (see here and here). But other teams haven’t been able to replicate the work, and others suggested that the collagen could be contamination.

The new study, led by materials scientist Sergio Bertazzo and paleontologist Susannah Maidment, both of Imperial College London, has a different strategy for hunting down ancient proteins. Bertazzo, an expert on how living bones incorporate minerals, uses a tool called a focused ion beam to slice through samples, leaving pristine surfaces that are ideal for high-resolution imaging studies. He teamed up with Maidment to apply the technique to eight chunks of dinosaur toe, rib, hip, leg, and claw.

What they found shocked them. Imaging the fresh-cut surfaces with scanning and transmission electron microscopes, “we didn’t see bone crystallites” as expected, Maidment says. “What we saw instead was soft tissue. It was completely unexpected. My initial response was these results are not real.” [emphasis mine]

It must be noted that the new research depends on many uncertainties that still need to be replicated or confirmed.

$28 billion spent on poor biomedical research?

2:32 pm

The uncertainty of science: A new study suggests that $28 billion is spent on biomedical research that no one can reproduce.

I have no doubt that a vast amount of medical research is so poorly done that no one else will ever be able to replicate the results. However, the article notes that the way the researchers came up with the $28 billion figure is quite questionable, reviewing only about two dozen studies and then extrapolating their numbers across the entire research field. This is highly uncertain and should be taken with a grain of salt.

Obamacare sets record for unpopularity with public

12:22 pm

Finding out what’s in it: A new poll has found that Obamacare, five years after it was passed, is more unpopular now then ever before.

Which is why the Republicans should do nothing to fix it should the Supreme Court rule against Obamacare subsidies in states with no health exchanges, and instead stick with full repeal followed by specific fixes to the previous laws.

I am even more convinced that full repeal is the right political approach after reading this leftwing reporter’s take on the situation. He thinks the above plan is stupid, knows the Democrats and Obama will never agree to it, but also knows that the public does not blame Obamacare in any way on the Republicans. As he notes,

And one of the reasons why Democrats should not assume that a ruling for the plaintiffs in King will totally backfire on Republicans is the cynical, but powerful, source of leverage that Thune is tapping into here: Democrats passed health care reform, and thus Democrats will get blamed for anything bad that happens to the health care system.

The above poll confirms this. The Republicans had better recognize this if they want to take full political advantage of it.

Rare large meteorite stolen from Australian museum

11:18 am

In a heist reminiscent of a Hollywood movie, two thieves in hooded jumpers and white masks stole a 25 pound meteorite the size of a soccer ball on Monday.

The only value of such a meteorite is among collectors, but to sell such a large and unique meteorite without being noticed would be impossible. It is theorized that the thieves might chop it up and sell the pieces to collectors instead.

Russia completes Soyuz launchpad at Vostochny

10:43 am

The competition heats up: Russia has completed assembly of the Soyuz-2 launch system at Vostochny a month ahead of schedule.

I must say that this story confuses me. Just this past weekend it was reported in the Russian press that they were abandoning efforts to build a Soyuz launchpad for manned flights at Vostochny and would instead focus on Angara. Why then are they finishing this Soyuz-2 launchpad now, and ahead of schedule?

One theory: The new launchpad might be for a new upgraded Soyuz rocket to be used for unmanned missions and thus different than the manned launchpad.

Or it might be that even though the government canceled it, workers continued to work on it and finished it, unaware of the cancellation. It is not unusual in big government projects for the right hand to not know what the left hand is doing.

UPDATE: My first theory was correct. Anatoly Zak of russianspaceweb.com has confirmed to me in an email that they only cancelled manned Soyuz flights at Vostochny. This launchpad will be used for an upgraded Soyuz rocket for unmanned flights.

Hole in observatory door was not caused by bullet

10:26 am

Curiouser and curiouser: In a statement to the press the Subaru Telescope has said that the hole in its door was not caused by a bullet this past weekend but has been known about for months and was caused by wind banging the door against a piece of equipment.

But on Monday, the observatory said in a statement the hole was caused by strong wind swinging a metal door into an instrument fixture attached to a wall. “We at Subaru Telescope are relieved that this is the case and regret the confusion caused by earlier reports,” the statement said.

A detective investigated Monday and determined the hole from the bolt on the wall was there about six months, police said. The observatory’s statement says the day crews knew about the hole from a severe winter storm earlier this year. The observatory didn’t immediately explain why someone reported it to police Saturday night.

The contradictions between the story released today and what was revealed yesterday is quite stark. My guess would be that someone at the telescope, unaware of the hole previously, saw it this weekend and panicked, thinking it caused by a bullet and fearful because of the illegal presence of protesters on the road to the mountain. It is also possible that someone at the telescope saw the hole for the first time and wanted to smear the demonstrators. It is also possible that the rumor was spread by a demonstrator who wanted to smear the astronomers, knowing that the false story would be quickly uncovered.

I could speculate for hours, pointlessly. The bottom line is that the lack of good will from the demonstrators is successfully spreading the ill will to all sides.

Parachute problems again for NASA’s flying saucer

5:06 pm

In its second flight today NASA’s engineering vehicle for testing Mars landing technologies, dubbed a flying saucer by the press because of its shape, had a similar problem as in its first flight, with its parachutes failing to inflate properly during landing.

More here. This test was not only to check out landing technologies, it was to check out the redesigned parachute that had failed in the previous test last year.

Want a law passed? Bribe your Senator!

12:30 pm

Good work if you can get it: A survey of the Senators who voted for the secret fast track trade legislation — whose language has still not been published for the public to read — has found that they all received huge donations in the past few months from businesses that support the legislation, while the law was being written and voted on.

Some were Democrats who held back until they got a lot of cash donations, then voted yes. Some were Republicans who took the money up front and then wrote the legislation. All told more than a million dollars in bribes were handed over to senators to guarantee their “yay” votes.

TSA fails to find links to terrorism of airport workers

10:46 am

Does this make you feel safer? An audit of the TSA has found that the agency failed to uncover the terrorist connections of 73 aviation workers when it did background checks of them.

According to TSA data, these individuals were employed by major airlines, airport vendors, and other employers. TSA did not identify these individuals through its vetting operations because it is not authorized to receive all terrorism-related categories under current interagency watchlisting policy,” the redacted report reads. “TSA acknowledged that these individuals were cleared for access to secure airport areas despite representing a potential transportation security threat,” it added.

The new audit comes on the heels of another damaging Inspector General report on TSA’s security measures, which found the aviation security body was unable to detect fake bombs and weapons in 95 percent of trial runs. Revealed last week in an ABC News report, the OIG’s findings resulted in the Acting TSA Administrator, Melvin Carraway’s, removal from the post.

The TSA is nothing more than childish feel-good theater used to convince Americans that the government has the right to sexually abuse them, if it wants. It does little to prevent hijackings or terrorist attacks. The smartest thing we could do is to shut it down, close down the security posts, and simply let Americans be armed on planes. Trust me, terrorists — being cowardly bullies who look for easy targets — would stay away, and no gun shots would ever get fired.

Problems at Stratolaunch

10:29 am

In the heat of competition: Stratolaunch and Orbital ATK have quietly parted ways as problems have developed in building Stratolaunch’s giant first stage aircraft.

The company went with a radical engineering idea — using a giant airplane as their first stage — which might turn out great but could just as easily become a disaster and failure. Such ideas are by their nature filled with many unknowns.

In a sense, this story validates SpaceX’s approach to developing new space technology, which is to take known engineering and to upgrade it while refining the production methods for building it to lower costs. With this approach, you lower risks by reducing the number of unknowns you have to deal with.

Bullet hole found in Mauna Kea observatory

10:20 am

Even as protesters continue to block the roads to the top of Mauna Kea to prevent construction of the Thirty Meter Telescope (TMT), workers at the Subaru Telescope at the mountain have reported a bullet hole in one door that had been put there sometime over the weekend.

No one knows who did it, or even if the hole was caused by a bullet, though that is what it looks like. The leader of the protests has of course denied any participation and condemned it.

I found this quote from the first link above (which spends a lot of time describing the heroic protesters who have been camping on the road) to be very revealing about this whole affair:

In an email Saturday, DLNR spokeswoman Deborah Ward said the area is not permitted for camping but did not respond to the Tribune-Herald’s questions about why the department has allowed the protesters to remain at the site. “Both state and county officials are monitoring the situation,” she wrote.

Gee, don’t we all remember how government officials turned a blind eye to tea party protests? Not! They did however allow illegal trespassing for Occupy Wall Street. In all these cases, the government officials reveal whose side they are on.

I personally think the astronomy community should organize a boycott of tourism to Hawaii. If their island is so sacred that outsiders shouldn’t be there, maybe we should hold them to their word. We would then find out how serious they really are about the island’s sacredness.

LightSail successfully deploys solar sail

9:58 am

Engineers have confirmed that the cubesat prototype LightSail has successfully deployed its solar sails.

This is I think only the second time a solar sail has successfully deployed in space. More significant to me is the fact that it is the first time this kind of complex engineering test has been tried using a cubesat. If cubesats can begin to handle these kinds of tasks, unmanned satellite technology is going to take a gigantic leap forward.

Dawn makes a movie of Ceres

9:28 am

Cool image time! Using images that Dawn has accumulated since it entered orbit around Ceres, scientists have created an animation showing the dwarf planet as it rotates.

Video below the fold. Note that this is an animation. They have filled in the gaps between images to make the rotation smooth, exaggerated the scale two times to bring out details, and added a background of stars that is not visible in the original images. Even so, this video is scientifically useful, as it shows Ceres in its entirety. It is also very spectacular.

Jets on Comet 67P/C-G now persist into the night

9:18 am

jets from Comet 67P/C-G

Cool image time! Rosetta’s high resolution camera is now finding that, due to increased activity as Comet 67P/C-G approaches the sun, jets of material now continue to evaporate off the surface even after sunset.

“Only recently have we begun to observe dust jets persisting even after sunset”, says OSIRIS Principal Investigator Holger Sierks from the Max Planck Institute for Solar System Research (MPS) in Germany. In the past months, the comet’s activity originated from illuminated areas on the day side. As soon as the Sun set, these jets subsided and did not re-awake until after the next sunrise. (An exception poses an image from 12 March, 2015 showing the onset of a dust jet on the brink of dawn.)

According to OSIRIS scientists, the jets now occurring even after sunset are another sign of the comet’s increasing activity. “Currently, 67P is rapidly approaching perihelion in mid-August”, says Sierks. At the time the image was taken, comet and Sun were only 270 million kilometers apart. “The solar irradiation is getting more and more intense, the illuminated surface warmer and warmer”, Sierks adds.

Because the jets are now remaining active into the night, it is allowing us to see more precisely their points of origin on the surface, which can then be studied more closely in daylight. Previously it was difficult in daylight to pinpoint the exact spot where the jets began.

LightSail deploys its solar sails

10:48 pm

Though full confirmation will not come until later tonight, telemetry from LightSail suggests that its solar sails have successfully begun deployment.

Telemetry received on the ground showed motor counts climbing to the halfway point before LightSail traveled out of range. Power levels were consistent with ground-based deployment tests, and the spacecraft’s cameras were on. “All indications are that the solar sail deployment was proceeding nominally,” wrote mission manager David Spencer in an email update.

They will have to wait until the cubesat comes back in range at 2:46 am (Eastern) to see if the deployment completed successfully, as well as download images.

Turkey’s Islamists lose Parliament in elections today

3:25 pm

Some good news: The increasingly authoritarian Islamic-controlled party of President Erdogan of Turkey was soundly defeated in elections today.

Turks went to the polls today in parliamentary elections, and the era of single-party Islamist rule appears to be over. President Recep Tayyip Erdogan had been counting on the continued rule of his AKP party to change the country’s constitution after these elections, consolidating his already increasingly authoritarian rule into something even more dastardly. But a 2/3 majority of AKP in parliament is needed to change the constitution.

Today, the Islamist party walked away with only 41 percent of seats. That’s an eight percent drop from 2011.

AKP still holds the most seats of any party, but it appears their effort to make the country more Islamic caused many people to go to the polls and vote against them. The result will likely be a coalition of other parties now controlling Parliament.

Bee die off hasn’t happened

11:39 am

The uncertainty of science: Despite numerous claims by environmentalists and scientists in the past decade that the bee population was dying off, new data from the Agriculture Department suggests that bee populations are now at a 20 year high.

The reason? It appears that beekeepers have been very innovative and creative when faced with disease or other problems that hurt bees. Driven by the profit motive and competition and free to act, they have come up with solutions.

State Department proposes fines for writing about guns without permission

11:31 am

New regulations being proposed by the Obama administration would require anyone writing on the web about guns to get approval first from the State Department or face serious fines.

In their current form, the ITAR do not (as a rule) regulate technical data that are in what the regulations call the ‘public domain.’ Essentially, this means data ‘which is published and which is generally accessible or available to the public’ through a variety of specified means. These include ‘at libraries open to the public or from which the public can obtain documents.’ Many have read this provision to include material that is posted on publicly available websites, since most public libraries these days make Internet access available to their patrons.

The ITAR, however, were originally promulgated in the days before the Internet. Some State Department officials now insist that anything published online in a generally-accessible location has essentially been ‘exported,’ as it would be accessible to foreign nationals both in the U.S. and overseas.

With the new proposal published on June 3, the State Department claims to be ‘clarifying’ the rules concerning ‘technical data’ posted online or otherwise ‘released’ into the ‘public domain.’ To the contrary, however, the proposal would institute a massive new prior restraint on free speech. This is because all such releases would require the ‘authorization’ of the government before they occurred. The cumbersome and time-consuming process of obtaining such authorizations, moreover, would make online communication about certain technical aspects of firearms and ammunition essentially impossible. [emphasis mine]

In your wildest dreams did you ever think we’d come to a time in the U.S. where the federal government thought it acceptable to require citizens to get their permission before they could publish something?

Obamacare bureaucracy threatens doctors who speak out

11:23 am

Finding out what’s in it: Doctors are finding that they better not criticize Obamacare in public or they will face retribution from its bureaucracy.

For physicians in this position, public advocacy against the ACA could be in violation of employment contracts or could be a source for dismissal. Most doctors’ contracts also include a two-year noncompete clause that essentially requires the doctor to move out of town once he or she leaves a specific job. So, running afoul of your employer by criticizing the ACA could result in not just losing your job but also forcing you to leave your hometown.

And that’s not all. Many doctors are also afraid of losing insurance contracts. The vast majority of doctors who are still private-practice owners are dependent on a handful of large insurance contracts for revenue. Speaking out against insurance companies — which were complicit in the ACA’s passage and are some of its primary beneficiaries — can result in cancellation of those contracts.

LightSail back in business?

8:57 am

The Planetary Society’s solar sail engineering test called LightSail has re-established communications with the ground, allowing for the possibility that it can finally achieve its solar sail deployment, the main purpose of the mission.

I had previously reported that the sails had deployed, but a commenter correctly noted that only the panels have deployed, not the sails themselves, which need full battery power. The communications problem has been related to a battery charging problem. They are hoping that the batteries will get charged by mid-day today when they will try to deploy the sails.

Manned flights from Vostochny delayed

9:02 am

In order to save construction costs at its new spaceport at Vostochny, Russia has decided to delay its first manned flight there until 2023.

They originally were going prepare a launchpad for Soyuz rockets so that they could do a manned launch at Vostochny as early as 2019, but had already admitted this was inefficient and had abandoned the plan. Now they have admitted that it will take until 2023 for them to get Vostochny and Angara ready for manned flights.

That it will still take almost 8 years to prepare a launchpad and get Angara ready to launch manned capsules, however, seems an ungodly long period of time. It should not take that long.

Hawaii’s highest court takes on TMT case

8:54 am

In a move that appears to be a victory for the protesters trying to shut down the construction of the Thirty Meter Telescope on Mauna Kea, Hawaii’s supreme court on Friday agreed to bypass lower court procedures and immediately consider the case.

It is even possible the court could rule that it is inappropriate to have any telescopes on Mauna Kea.

Airbus unveils its first stage re-useability concept

2:32 pm

The competition heats up: Airbus unveiled today its prototype design to recover and reuse the engines and avionics of its Ariane rockets.

Herve Gilibert, technical director for Airbus’ Space Systems division, said the Adeline propulsion unit — engine and avionics — is where lies most of the value of the first stage. The Airbus team concluded that SpaceX’s design of returning the full stage to Earth could be simplified by separating the propulsion bay from the rest of the stage, protecting the motor on reentry and, using the winglets and turbofans, return horizontally to a conventional air strip. “We are using an aerodynamic shield so that the motor is not subjected to such high stress on reentry,” Gilibert said. “We need very little fuel for the turbofans and the performance penalty we pay for the Ariane 6 launcher is far less than the 30 percent or more performance penalty that SpaceX pays for the reusable Falcon 9 first stage.

Gee, for decades Arianespace and Boeing and Lockheed Martin and everyone else in the launch industry insisted it made no economic sense to try to recover and reuse the first stage of their rockets. Then SpaceX comes along and makes an effort to do so, without as yet even coming close, and suddenly everyone agrees it is economically essential to do it as well.

Isn’t competition wonderful?

Republicans propose replacement after they repeal Obamacare

9:35 am

A plan revealed today and endorsed by nearly 170 House Republicans would repeal Obamacare in total and then introduce a number of tweaks to the many past healthcare laws in an effort to reduce costs and increase competition.

A summary of the 192 page proposal can be read here. Take a look. It is far from perfect, but its main advantage, from what I can see, is that it doesn’t try to fiddle with Obamacare, it gets rid of it and then attempts to make changes to the laws that had existed before Obamacare was passed.

In other words, it tries to do what should have been done back in 2010, when the Democrats forced their crap bill (which most of them didn’t read) down our throats without any negotiations.

Should the Supreme Court rule that the Obamacare subsidies are illegal and the press tries to falsely blame Republicans for that disaster, this bill should be noted as a reasonable offer to solve the problem.

Scott Walker reveals his inner Democrat

9:11 am

In a disappointing move, Scott Walker, Wisconsin governor and presidential candidate, has announced his support for state funding for a new basketball arena, which would require increased taxes as well.

It seems to me that Republicans, no matter how conservative, always eventually disappoint and evolve into big government stooges. This happens partly because they are politicians, who are generally a lower form of life, and partly because politicians tend to do what the voting public wants. Sadly, for the past century the American voting public — even the so-called conservative voting public — has consistently voted for more government handouts, which is why Republicans evolve to the left with time.

For Walker this is unfortunately seems to be happening sooner than I had hoped.
