Charon in color

11:39 am

Charon

The New Horizons science team has released new high resolution images of Pluto’s moon Charon, including the global enhanced color view on the right.

High-resolution images of the Pluto-facing hemisphere of Charon, taken by New Horizons as the spacecraft sped through the Pluto system on July 14, and transmitted to Earth on Sept. 21, reveal details of a belt of fractures and canyons just north of the moon’s equator. This great canyon system stretches across the entire face of Charon, more than a thousand miles, and probably around onto Charon’s far side. Four times as long as the Grand Canyon, and twice as deep in places, these faults and canyons indicate a titanic geological upheaval in Charon’s past. “It looks like the entire crust of Charon has been split open,” said John Spencer, deputy lead for GGI at the Southwest Research Institute in Boulder, Colorado. “In respect to its size relative to Charon, this feature is much like the vast Valles Marineris canyon system on Mars.”

The team has also discovered that the plains south of the canyon, informally referred to as Vulcan Planum, have fewer large craters than the regions to the north, indicating that they are noticeably younger. The smoothness of the plains, as well as their grooves and faint ridges, are clear signs of wide-scale resurfacing.

In many ways these images remind me of an upside-down Mars, with the smooth lower plains in the south instead of the north. Obviously, the causes on Charon are going to be significantly different than those on Mars.

Vostochny launch building built to the wrong size

8:37 am

Government marches on! The Russians have just discovered that their Soyuz 2 rocket does not fit in the building just finished at their new spaceport at Vostochny.

The cutting-edge facility was meant be ready for launches of Soyuz-2 rockets in December, but an unidentified space agency of a of a told the TASS news agency of a of a late Thursday that the rocket would not fit inside the assembly building where its parts are stacked and tested before launch. The building “has been designed for a different modification of the Soyuz rocket,” the source said, according to news website Medusa, which picked up the story from TASS.

The rocket had just been delivered to Vostochny for assembly, so this report, though unconfirmed at this time, fits well with current events.

NASA pulls funding from private asteroid hunter

10:57 pm

Because of a failure to meet its developmental deadlines, NASA has cut its ties with the privately funded Sentinel satellite, designed to spot 90% of all near Earth asteroids that might pose a threat to the Earth.

The problem for the B612 Foundation, the private company committed to building Sentinel, is that they haven’t clearly laid out a way any investors could make money from the satellite. Thus, they have so far raised only $1.6 million from private sources. They need almost half a billion to build it, according to their own budget numbers.

Congress places additional limits on Russian rocket engine use

10:48 pm

Bad news for ULA and the Atlas 5: A defense bill approved by the Congressional negotiators has placed further limits on the number of Russian rocket engines ULA can use in future Atlas 5 government launches.

The bill, which still faces an Obama veto, only allows ULA to use 9 more Russian engines. The company however says it needs to have at least 18 available to keep its ability to launch government payloads while it develops its new Vulcan rocket.

Read the whole article. The political complexity of this whole situation does not bode well for ULA or its Vulcan rocket. Too many players with too many conflicting goals appear to make it difficult for the company to push the development forward efficiently.

Smallsat company buys its own Falcon 9 rocket to launch 20 satelites

10:40 pm

The competition heats up: Spaceflight Industries has purchased a single dedicated Falcon 9 rocket launch to launch 20 small satellites sometime in 2017.

Buying a dedicated launch, rather that seeking excess capacity on other launches, provides Spaceflight with more than just additional payload capacity. Secondary or “rideshare” payloads are subject to the schedule of the primary capability, and can be bumped off the launch if the mass of the primary payload grows. With a dedicated mission, Spaceflight is in greater control. “It helps us establish a regular cadence of launches,” Blake said. “We can book all kinds of rideshare passengers onto something that is going to be there at a certain time to a certain orbit.”

This purchase also indicates the growing strength of the smallsat industry. These companies are beginning to gain the investment capital to buy their own launches rather than fly as secondary payloads.

Development of Blue Origin’s BE-4 rocket engine moves forward

10:33 pm

The competition heats up: Blue Origin has completed more than 100 development tests of its new BE-4 rocket engine, being developed for ULA.

Much of this announcement sounds like public relations blather. However, it contained this nugget of information that is crucial to understanding why this engine is likely to get built quickly:

The BE-4 engine is also the leading candidate to be used in the first stage of ULA’s Vulcan vehicle. Speaking to reporters after the Sept. 15 Florida event, Blue Origin founder Jeff Bezos said that while he was aware of competing engines for the Vulcan, like the AR-1 under development by Aerojet Rocketdyne, he was focused on completing the BE-4. “We’re going to build the best 21st century engine that we can for ULA,” he said. “Ultimately they will make the decision about what they want to do.”

Bezos also noted that, unlike the AR-1 or other concepts, Blue Origin was not seeking funding from the U.S. Air Force to help pay for development of the BE-4. “The most unique feature of the BE-4 engine is that it’s fully funded,” he said. “It’s not something you see in rocket engine programs very often.” [emphasis mine]

Aerojet Rocketdyne wants the government to pay for its new AR-1 engine. To get that done, they need to lobby Congress for funds that are simply unreliable in these days of budget-cutting. Moreover, it means that Aerojet Rocketdyne is not fully committed to the engine: if the funds don’t arrive they won’t build it.

Blue Origin is going forward, fully committed, and will likely deliver, if only because they can’t get their investment back until they do.

Creeping towards commercial and private weather satellites

10:13 pm

Link here. The editorial at Space News outlines the effort in Congress to force NOAA to buy weather data supplied by private commercial satellite companies rather than build its own satellites. It also outlines what might be the major reason private companies have never been able to make a profit in the field:

The agency [NOAA] is obliged as a member the World Meteorological Organization [WMO] to share weather data openly and freely with other nations. If that obligation applies to commercially procured data, as NOAA insists, it could dramatically shrink the addressable global market for commercial weather data — to the point that it could shatter business models. – See more at: http://spacenews.com/editorial-inching-toward-a-commercial-weather-policy/#sthash.vG9fs3Sj.dpuf

In other words, private companies can’t sell their data because of the U.S.’s membership in the WMO, which requires that data to be made available for free. To make the commercialization of weather work, the U.S. is going to have to pull out of WMO, something I think will be difficult to sell to Congress.

Virgin Galactic tests new rocket engine

10:04 pm

The competition heats up? Virgin Galactic has released video of a test burn of a new engine designed to work with its LauncherOne rocket.

I put a question mark above because I have become very skeptical of any press announcements out of Virgin Galactic. They might have made progress on this new engine, and it also appears that they are doing engine work first for developing LauncherOne, a wise plan. However, their track record with SpaceShipTwo makes me doubtful about their ability to follow through. They need to produce to make me a believer once again.

Back from the Grand Canyon

4:27 pm

Diane and Gang on the Tonto Plateau

Diane and I just got home and are in the process of catching up. Posting shall resume this weekend, maybe tonight! Meanwhile, I was pleasantly surprised that even with my absence, my thoughtful readers (even ones I sometimes disagree with) have been keeping things lively here with some intelligent debate. Kudos to you all!

And as always, the Canyon was what it always is, magnificent and awe-inspiring. The picture on the right shows us hiking on the Tonto Plateau, about 4000 feet down from the rim but above the Colorado River 1000 feet below. If you look real close you can see the tiny figures of Diane and others on the trail.

The modern glassmaker

6:01 pm

An evening pause: Though the last two minutes are a commercial and can be ignored, the rest of this video shows the modern way glass is produced for our technological society. Most fascinating, especially because the way it is done surprised me.

Hat tip Rocco.

Back to the Grand Canyon

12:01 pm

Hiking in the Grand Canyon

Diane and I are about to leave for our annual hike to the bottom of the Grand Canyon. Though I might be able to post during the drive north today and from the hotel on the rim tonight, from Tuesday until Thursday I will be out of touch with the world of computers, a welcome break that I do need periodically.

Unlike previous trips, this time we are going with a bunch of friends. Last year I obtained a reservation for a 10-person cabin at Phantom Ranch in the Canyon so that we could all be together. Should be a lot of fun!

Comet 67P/C-G was formed by a soft collision

9:04 am

Scientists, using data from Rosetta, have concluded that Comet 67P/C-G’s double lobed shape was caused by the slow-motion collision of two distinct comets.

By using high-resolution images taken between 6 August 2014 and 17 March 2015 to study the layers of material seen all over the nucleus, they have shown that the shape arose from a low-speed collision between two fully fledged, separately formed comets. “It is clear from the images that both lobes have an outer envelope of material organised in distinct layers, and we think these extend for several hundred metres below the surface,” says Matteo Massironi, lead author from the University of Padova, Italy, and an associate scientist of the OSIRIS team. “You can imagine the layering a bit like an onion, except in this case we are considering two separate onions of differing size that have grown independently before fusing together.”

While erosion continues to eat away at the comet’s surface, changing its shape, the two lobes formed separately, though in much the same way.

India launches its first space observatory

8:46 am

The competition heats up: India today successfully launched Astrosat, its first space telescope.

ASTROSAT, with a mission life of five years, is armed with telescopes that will simultaneously study the space in visible light, ultraviolet (UV) rays and low- and high-energy X-rays, plus an X-ray scanning sky monitor to detect transient X-ray emissions and γ-ray bursts. The observatory aims to study star-birth regions and high-energy processes, including binary star systems of neutron stars and black holes.

This space observatory fills several gaps that have existed in astronomical research since the shut down of NASA’s Rossi X-Ray Timing Explorer in 2012 as well as the International Ultraviolet Explorer in 1996.

The launch also put six other small satellites into orbit, demonstrating once again the reliability of India’s smaller Polar Satellite Launch Vehicle (PSLV).

New EPA ozone regulations based on fantasy

4:46 pm

We’re here to help you: New proposed EPA regulations for reducing ozone are expected to cost trillions to enforce, even though there is no evidence that the regulations will do anything to improve health.

In the name of fighting asthma, the Environmental Protection Agency (EPA) requested permission to decrease the ozone standard  — the amount of ozone allowed in the atmosphere — to a level some scientists say is physically impossible to achieve. One organization estimates the cost to implement these new rules will be $1.1 trillion. Even worse, data shows that as ozone levels in the U.S. have decreased, asthma cases have increased.

This regulation may be the most expensive in history, and bring absolutely no health benefits.

Worse, there is absolutely no scientific basis for these ozone regulations.

While average levels of ozone have decreased 33 percent since 1980, the number of asthma patients has increased over that time. The Global Asthma Report for 2014 lists environmental factors which lead to asthma, but never mentions smog or ozone. The National Institutes of Health does not list climate change or ozone as a cause of asthma mainly because the exact causes are unknown. Excessive hygiene once was considered the primary cause, but this view has been mostly refuted. “The World Health Organization report “Ambient (Outdoor) Air Quality and Health” does make the argument that ozone may trigger asthma, but it does not refute the negative correlation between improving air quality and the worsening Asthma epidemic in the US.”

While proposing the new standard, the EPA cited a study of which the agency itself had previously said “it is convenient for fitting the model, but it is not accurate.” As Tony Cox pointed out, “there is abundant historical data on ozone levels and asthma levels in U.S. cities and counties over the past 20 years,” so it is relatively easy to see if decreasing ozone has positive effects on respiratory health. It does not.

Read the whole thing. The only reason the EPA is going to try to impose this regulation, which by the way is so stringent that it will likely be impossible for anyone to meet it, is because they can. It is a power play, pure and simple, imposed by appointed fascist bureaucrats who have an ideology that they intend to force on everyone else, regardless of the harm it does.

Boeing’s first stealth plane concept

10:57 am

Boeing has just released the few remaining photos and documents relating to a 1960s stealth plane concept, including pictures of a half-scale prototype.

The concept dates back to the early 1960s, with a one-half scale model of the aircraft being built sometime between 1962 and 1963. The aircraft was an exercise in utilizing specific materials and shapes to drastically reduce the radar cross-section of a tactical aircraft. From this pioneering design, five Boeing “stealth” patents were awarded, and they only appear to have shown up in public records in the early 1990s, decades after they were officially filed. 

The model of Quiet Bird was said to have been tested at Boeing’s Wichita facility in 1962-1963, all of which occurred on a radar range. No actual flight testing of Quiet Bird itself was said to have happened, though. But the tests were highly successful: they proved that it was possible to drastically decrease the radar signature of a tactical aircraft.

Using fish to study bone loss in weightlessness

9:04 pm

A Japanese experiment on ISS, comparing the development of fish in weightlessness with those on the ground, has provided` scientists more information about bone density loss in weightlessness.

Akira Kudo at Tokyo Institute of Technology, together with scientists across Japan, have shown that medaka fish reared on the International Space Station for 56 days experienced increased osteoclast activity – bone cells involved in the re-absorption of bone tissue – likely leading to a subsequent reduction of bone density. They also found several genes that were upregulated in the fish during the space mission. The team generated fish with osteoclasts that emit a fluorescent signal. They sent 24 fish into space as juveniles, and monitored their development for 56 days under microgravity. The results were compared with a fish control group kept on Earth.

Kudo and his team found that bone mineral density in the pharyngeal bone (the jaw bone at the back of the throat) and the teeth of the fish reduced significantly, with decreased calcification by day 56 compared with the control group. This thinning of bone was accompanied by an increase in the volume and activity of osteoclasts. The team conducted whole transcriptome analysis of the fish jaws, and uncovered two strongly upregulated genes (fkbp5 and ddit4), together with 15 other mitochondria-related genes whose expression was also enhanced. Reduced movement under microgravity also has an influence. The fish began to exhibit unusual behavior towards the latter stages of their stay in space, showing motionless at day 47.

What the data mostly confirms is that long-term weightlessness is a bad thing for the development of bones, and not just in humans. Whether scientists can use these results to counter these harmful effects is not clear, however.

66% of all surface climate data is adjusted

8:56 am

The uncertainty of science: An analysis of the surface global weather data, dubbed GHCN and used by NASA’s Goddard Institute of Space Sciences (GISS) to demonstrate the climate has been warming for the past century, has found that 66% of that data is adjusted or estimated and is not based on the actual raw data.

Overall, from 1880 to the present, approximately 66% of the temperature data in the adjusted GHCN temperature data consists of estimated values produced by adjustment models, while 34% of the data are raw values retained from direct measurements. The rural split is 60% estimated, 40% retained. The non-rural split is 68% estimated, 32% retained. Total non-rural measurements outpace rural measurements by a factor of 3x.

The estimates produced by NOAA for the GHNC data introduce a warming trend of approximately a quarter degree C per century. Those estimates are produced at a slightly higher rate for non-rural stations than rural stations over most of the record. During the first 60 years of the record measurements were estimated at a rate of about 75%, with the rate gradually dropping to 40% in the early 1990s, followed by a brief spike in the rate before resuming the drop to its present level.

Approximately 7% of the raw data is discarded. If this data were included as-is in the final record it would likely introduce a warming component from 1880 to 1950, followed by a cooling component from 1951 to the present.

As I have noted previously, all the adjustments cool the past and warm the present, a pattern that is just not realistic in the real world, and could only exist if the people doing the adjustment are either not recognizing their biases or are consciously manipulating the data to prove those biases.

Either way, the surface temperature data as released by GISS is simply not trustworthy for determining the changes in the Earth’s climate over the past few centuries.

First rocket arrives at Vostochny

8:25 am

The competition heats up: The Russians have now delivered to Vostochny the first Soyuz rocket for launch from that spaceport.

The launch is still planned for December, though no one would be surprised if it got delayed.

One minor but interesting thing to note at the link above. The pictures of the train and the containers holding the rocket sections were taken by none other than Dmitry Rogozin, the Russian deputy prime minister whom Putin himself has placed in charge of the construction of Vostochny. This is as if Obama put Biden in charge of NASA’s SLS program, and Biden himself took pictures of some construction event for the news media.

Boehner steps down

10:31 am

Good news: House Speaker John Boehner (R-Ohio) today announced that he will resign as speaker as of the end of October.

I’ve already seen a number of stories suggesting that Boehner’s second-in-command, Kevin McCarthy (R-California), is the likely replacement. McCarthy would not be much different than Boehner, except that he will know that the conservative wing of the Republican Party was able to force out his predecessor for not supporting conservative objectives. I expect we will thus see the House leadership develop a little more spine in future conflicts with the Democrats.

This is all part of a long term process. Every election that increases the number of conservatives in Congress increases their ability to achieve their goals. Nor is this unusual. I saw the same thing in the 1960s. At the time the public wanted Congress to pass very leftwing legislation. Congress wasn’t willing to do it. It took a decade, until the late 1970s, before Congress had followed the public’s lead and become as liberal as the public.

There is always a lag. I expect the conservative momentum to continue to accelerate in the coming years.

Rosetta data reveals how a comet evaporates

9:57 am

Newly released Rosetta data has shown, for at least one area on the surface of Comet 67P/C-G, the process by which the surface ice is replaced by water ice from below as the comet rotates and sunlight causes the surface ice to evaporate away.

The data suggest that water ice on and a few centimetres below the surface ‘sublimates’ when illuminated by sunlight, turning it into gas that then flows away from the comet. Then, as the comet rotates and the same region falls into darkness, the surface rapidly cools again. However, the underlying layers remain warm owing to the sunlight they received in the previous hours, and, as a result, subsurface water ice keeps sublimating and finding its way to the surface through the comet’s porous interior.

But as soon as this ‘underground’ water vapour reaches the cold surface, it freezes again, blanketing that patch of comet surface with a thin layer of fresh ice. Eventually, as the Sun rises again over this part of the surface on the next comet day, the molecules in the newly formed ice layer are the first to sublimate and flow away from the comet, restarting the cycle.

They discovered this process when they noticed surface ice evaporating in this region during the comet’s 6-hour day and then getting resurfaced with ice during the comet’s 6-hour night.

Meanwhile, Rosetta is about to move as much as 1500 kilometers away from the comet for several weeks so that its scientists can study its coma more broadly.

Aerojet is considering increasing its $2 billion offer to buy ULA

9:29 am

The competition heats up: A news report today suggests that Aeroject Rocketdyne is considering increasing its $2 billion bid to buy ULA, thus forcing that company to use its rocket engines rather than Blue Origin’s.

The article contains a lot of information that helps explain the background behind Aerojet Rocketdyne’s offer as well as ULA’s recent switch to Blue Origin. For one thing, ULA apparently dumped Aeroject because the company refused to invest any of its own money in developing a new rocket engine.

Last summer, Aerojet’s board also rejected ULA’s request that Aerojet invest $300 million to accelerate work on the AR-1 engine it is developing as an alternative to the Russian RD-180 engine that powers ULA’s Atlas V rocket, the sources said. … Aerojet’s refusal to invest more in the AR-1 engine ultimately drove ULA to opt for the BE-4 engine being developed by privately held Blue Origin, which is owned by Amazon.com founder and billionaire Jeff Bezos, the sources said.

More significant, it appears that the Rocketdyne portion of the company is owned by the Russians!

An Aerojet takeover of ULA would also require Russia to give its regulatory approval and transfer a technology license for use of the RD-180 engines, according to two of the sources. Russia refused to transfer the license to Aerojet when it bought Rocketdyne from Pratt & Whitney, a United Technologies Corp (UTX.N) unit in 2013, forcing Pratt to retain control of a small company that brokers RD-180 sales, and could be more reluctant to do so now, the sources said.

While the quote above is somewhat confusing, it certainly suggests that, with Congress banning the use of Russian-built engines in American rockets, using Aerojet Rocketdyne engines by ULA has become problematic.

In related more bad news for Aeroject Rocketdyne, the company has just agreed to pay Orbital ATK $50 million in connection with last year’s Antares launch failure. In addition, they will take back the Russian-built engines they refurshed and sold to Orbital. The agreement also ends the company’s part in Antares.

China debuts another new rocket

9:10 am

The competition heats up: China successfully completed the first launch of another new rocket today, putting three technology satellites into orbit with its solid-fueled Long March 11 rocket.

The Long March-11 (Chang Zhwng-11) is a small solid-fueled quick-reaction launch vehicle developed by the China Academy of Launch Vehicle Technology (CALT). It’s goal is to provide an easy to operate quick-reaction launch vehicle, that can remain in storage for long period and to provide a reliably launch on short notice. Very little is known about the rocket, with only one badly taken photo available on the internet. However, LM-11 is known to be a solid-fueled launch vehicle equipped with a liquid-fueled trim stage.

Moreover, the three satellites the rocket put in orbit are cubesats designed to test formation flying technologies. This puts China in the forefront of the effort to make these tiny satellites capable of doing what larger satellites now do, thus making possible the eventual replacement of those more costly larger satellites.

New Pluto images

4:07 pm

thumbnail of Pluto closeup

Cool image time! The New Horizons team has released some new images. A thumbnail of what I think is the most interesting image is shown on the right. Be sure to look at the full resolution image. It shows a flat plain of what look like frozen polygon plates with a thin layer of what appear to be dunes. In the center some rocks poke out like islands, with what looks like a wind-swept wake to the right. The wake could be caused by Pluto’s very thin atmosphere. Or maybe there are currents that slowly push the frozen plates past the harder rocks (which probably are ice, which in Pluto’s very cold environment has the structural strength of granite).

These images were posted on the New Horizons website with no accompanying press release. I think the science team has decided it will just upload them, and reserve press releases for when they have accumulated enough data to announce some intelligent conclusions. Right now, they can only speculate as wildly as I from these images. It is reasonable to give them the time to assess the data more closely before announcing any explanations. At the same time, we should also congratulate them for posting the images immediately so that others can see them.

Update: a press release was released, though it really doesn’t add much except review the images.

Obamacare causes health insurance deductibles to skyrocket

2:48 pm

Finding out what’s in it: Health insurance deductibles have gone up seven times faster than the rate of inflation since Obamacare became law.

According to a new report by the Kaiser Family Foundation and the Health Research & Educational Trust, the increase brings the average deductible that workers must pay for their health insurance plans to $1,077; more than triple what it was a decade ago. As reported in the L.A. Times, “That is seven times faster than wages have risen in the same period.”

Kaiser Family Foundation president Drew Altman said, “It’s a quiet revolution. When deductibles are rising seven times faster than wages … it means that people can’t pay their rent. … They can’t buy their gas. They can’t eat.” As a comparison, “workers’ wages increased 1.9% between April 2014 and April 2015, according to federal data analyzed by the report’s authors.” The news is also bad for family plans as, the “average family plan cost workers $4,955, up 3% from last year.”.

Obviously this is the fault of the Republicans campaigning for president. Their opposition to Obama and the Democrats is certainly the reason why Obamacare continues to be such a unmitigated disaster for Americans.
