White nose syndrome found on Washington state bat

4:08 pm

Bad news for bats: Scientists have confirmed a bat with white nose syndrome in the state of Washington, 1,300 miles further west than the previous detection.

On March 11, hikers found the sick bat about 30 miles east of Seattle near North Bend, and took it to Progressive Animal Welfare Society (PAWS) for care. The bat died two days later, and had visible symptoms of a skin infection common in bats with WNS. PAWS then submitted the bat for testing to the USGS National Wildlife Health Center, which confirmed through fungal culture, molecular and pathology analyses that it had WNS.

I hate to express such a thought, but I can’t help wonder about the legitimacy of this detection. It is so far west and so far from the nearest other bat with white nose syndrome I cannot understand how this bat came to be infected, naturally. In order for this discovery to be confirmed they are going to have to detect it again, and more than once, on a number of bats. Otherwise, it will remain suspect and a possible false positive.

The worst part of this is that the government is surely going to begin instituting draconian measures to protect the bats in Washington, as well as across the entire western United States, even before this detection is confirmed. Having this single detection will make it much easier for government officials to ban humans from many more places, even though white nose syndrome is nowhere close.

India signs deal for its own LIGO

11:56 am

India today signed an agreement with the National Science Foundation to build its own LIGO gravitational wave detector

This deal, combined with the possibility that TMT might move to India as well, suggests that India is about to move aggressively from the Third World to the First. And the reason, after decades of wallowing in poverty and failure, is that they finally abandoned in the late 1990s the Soviet models of socialism and communism and embraced private enterprise and capitalism, ideas championed by the United States.

If only some modern Americans would do the same.

OneWeb begins hiring in Florida

10:03 am

The competition heats up: The new satellite company OneWeb, with plans to launch a constellation of 900 satellites beginning next year, has begun hiring engineers for a manufacturing plant it intends to locate in Florida.

The article also notes the construction start of a new building that is suspected but not confirmed as the location of that manufacturing plant.

OneWeb’s existence is visible proof of my contention that if the launch business can lower the cost to orbit it will create new customers who can afford to buy the product. OneWeb is partly lowering the cost on its own by using small cubesat-like satellites, but it is also taking advantage of the renewed competition in the launch industry to get better deals on buying the rockets it needs to launch those satellites.

Earth forming around sun-like star?

9:51 am

proto-planetary disk

Worlds without end: The ground-based telescope ALMA has imaged a proto-planetary disk around a sun-like star that suggests an exoEarth is forming there the same distance from the star as our Earth is from our Sun.

The star, TW Hydrae, is a popular target of study for astronomers because of its proximity to Earth (approximately 175 light-years away) and its status as a veritable newborn (about 10 million years old). It also has a face-on orientation as seen from Earth. This affords astronomers a rare, undistorted view of the complete disk. “Previous studies with optical and radio telescopes confirm that this star hosts a prominent disk with features that strongly suggest planets are beginning to coalesce,” said Sean Andrews with the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., and lead author on a paper published today in Astrophysical Journal Letters. “The new ALMA images show the disk in unprecedented detail, revealing a series of concentric dusty bright rings and dark gaps, including intriguing features that suggest a planet with an Earth-like orbit is forming there.”

Other pronounced gap features are located 3 billion and 6 billion kilometers from the central star, similar to the distances from the Sun to Uranus and Pluto in our own Solar System.

The image above right is the inner section of that disk, showing the gap at one astronomical unit, or about 100 million miles from the star, the same as the distance of the Earth from the Sun. Essentially, this relatively close star system is providing us a perfect opportunity to study the formation of a solar system not unlike our own.

Further chaos at Vostochny

9:16 am

One week after the Moscow Commercial Court ordered the contractor building the new Russian spaceport Vostochny to repay $52 million in bank loans, that contractor has now filed three lawsuits totaling $17.9 million against the organization that runs the spaceport.

The new lawsuits suggest that even as the contractor’s managers were embezzling millions from the spaceport, the spaceport organization was also pocketing some money that was supposed to go to the contractor.

Russia: a true worker’s paradise!

Russia selling Sea Launch?

12:12 am

The competition heats up? Though he couldn’t reveal any details, the director of Russian space agency Roscosmos today said that they have found a buyer for Sea Launch.

“I cannot tell you who the investor is, or the value of the contract, due to certain obligations. I hope that we will have something to say about it by the end of April,” Komarov said. He did, however, say that investors from the U.S., Australia, China and Europe have expressed interest in the project.

Because Sea Launch is a floating launch platform, there really is no reason the company can’t be taken over by anyone in the world. And should the buyer use the Ukrainian Zenit rocket that the platform was designed to use, the technical problems might be reduced as well.

Emory University alumni push back against free speech attacks

12:40 pm

Push back: Emory University alumini are circulating a petition calling for the university to recommit itself to free speech instead of pandering to protesters demanding “emotional comfort, ideological conformity, and yes, ‘safe environments’.”

The petition was authored by alumni Matthew Walker and Ed Thayer, who said this:

“My Emory experience, which I look upon fondly, was periodically defined by eruptions of illiberal behavior from various student groups, although nothing as shrill and totalitarian as we are witnessing today,” Thayer said, adding that Emory administrators used to err on the side of free speech. “Nowadays they seem inclined to appease the worst intolerant and alarmist instincts of some students, while undercutting the foundations of free speech, tolerance, and a robust debate, which should thrive at a university.

Matthew Walker, for his part, summed up the whole situation in one word: “Unacceptable.”

The article above begins by focusing on how the university president has backed down from his original willingness to support the squelching of free speech. I suspect this pressure from alumni, who with most universities provide a great deal of financial support, is making him rethink his positions.

Another subsidized solar power company going bust?

11:13 am

Your tax dollars at work! The U.S.’s largest solar power company, heavily subsidized by the federal government, now faces bankruptcy.

An SEC filing from TerraForm Global, a unit of SunEdison, claims “due to SunEdison’s liquidity difficulties, there is a substantial risk that SunEdison will soon seek bankruptcy protection.” Both SunEdison and TerraForm are delaying the filing of their annual financial report to the SEC.

News of SunEdison’s impending bankruptcy filing comes after the company’s shares fell 95 percent in the past 12 months, with shares now trading for less than $1 for the first time since the green energy company went public in 1995. SunEdison’s market value fell from $10 billion in July 2015 to around $400 million today.

The news also comes after the SEC announced it was launching an investigation into SunEdison’s disclosures to shareholders regarding the company’s liquidity. SEC enforcement officials “are looking into whether SunEdison overstated its liquidity last fall when it told investors it had more than $1 billion in cash,” according to The Wall Street Journal.

…The pro-labor union group Good Jobs First reported last year that SunEdison and its subsidiaries got nearly $650 million in subsidies and tax credits from the federal government since 2000. It was the 13th most heavily-subsidized company in America. This includes nearly $4.6 million in subsidies from the Department of Energy and Department of Treasury. Watchdog.org reported in October 2015 that SunEdison had gotten nearly $4.6 million from the Obama administration, including funding to build semi-conductors. A SunEdison bankruptcy could leave taxpayers on the hook for more than $2 billion.

But hey, what’s a few billion here or there, if the cause is worthwhile?

Using lasers to travel to the stars

9:44 am

The competition really heats up! A research team at the University of California, Santa Barbara (UCSB) has proposed that an array of space-based lasers can be used to accelerate a solar sail to speeds as much as 26% the speed of light, thus making interstellar travel possible.

[The] key breakthrough was the development of modular arrays of synchronized high-power lasers, fed by a common “seed laser.” The modularity removes the need for building powerful lasers as a single device, splitting them instead into manageable parts and powering the seed laser with relatively little energy. Lockheed Martin has recently exploited this advance to manufacture powerful new weapons for the US Army. In March last year, the aerospace and defense giant demonstrated a 30 kW laser weapon (and its devastating effect on a truck). By October, the laser’s power had already doubled to 60 kW and offered the option to reach 120 kW by linking two modules using off-the-shelf components.

The UCSB researchers refer to their own planned arrays as DE-STAR (Directed Energy System for Targeting of Asteroids and ExploRation), with a trailing number to denote their size. A DE-STAR-1 would be a square array 10 meters (33 ft) per side and about as powerful as Lockheed’s latest; at the other end of the spectrum, a DE-STAR-4 would be a 70 GW array covering a massive area of 100 square kilometers (39 square miles).

…Lubin stresses that even a relatively modest orbital array could offer interesting propulsion capabilities to CubeSats and nanosatellites headed beyond Earth orbit, and that useful initial tests would still be conducted on the ground first on one-meter (3-ft) arrays, gradually ramping up toward assembling small arrays in orbit. While even a small laser array could accelerate probes of all sizes, the larger 70-GW system would of course be the most powerful, capable of generating enough thrust to send a CubeSat probe to Mars in eight hours – or a much larger 10,000-kg (22,000-lb) craft to the same destination in a single month, down from a typical six to eight.

Further upgrades would make it possible to send a cubesate and its lightsail to Alpha Centuri in about fifteen years.

The important point here is that it appears that all the technology for building this already exists, or is relatively straightforward to develop.
