Ground tests of SpaceShipTwo’s engines continue.

9:20 am

Ground tests of SpaceShipTwo’s engines continue.

No flight tests have occurred in four months, however, which suggests that they have decided to abandon their first engine design and are now doing these new ground tests to prove the reliability of the new engine before proceeding to flight tests. The lack of flight tests also suggests that Richard Branson’s most recent announcement that he will definitely fly as a passenger this year is most likely hogwash.

The trip of what is essentially a circuit breaker on ISS has reduced the station’s power by about 12.5%.

The trip of what is essentially a circuit breaker on ISS has reduced the station’s power by about 12.5%.

The cause and solution has not yet been isolated. The loss of power at this point is not critical, and has not effected any experiments or the safety of the crew.

The article itself gives a very detailed and informative outline of the system and what has happened, though you have to spend the time to wade through the alphabet soup of NASA terminology — SSU, SAWs, VDC, DCSUs, MBSUs, DDCUs, POR — that NASA uses.

The 2013 Walter Duranty Prize for mendacious journalism was announced on Monday.

9:39 am

The 2013 Walter Duranty Prize for mendacious journalism was announced on Monday.

This prize – in honor (or, more accurately, dishonor) of Walter Duranty, the New York Times Moscow correspondent during the 1920s and 1930s – was first given in 2011 by PJ Media and The New Criterion. For various reasons of sloth and bureaucracy, it has taken the organizations a year and a half to award a second round, but the prize will now be put on an annual basis.

A second award – The Rather (after Dan Rather) — for lifetime achievement in mendacious journalism was initiated this year.

Sadly, the number of qualified candidates far exceeded the number of prizes.

In related news: “A suspected arms dealer, an allegedly crooked mayor dealing in White House access, and a cowardly attorney general walk into a bar. Even if it’s the bar right next door to The Washington Post, would they get any coverage? If they’re Democrats, the answer is probably no.”

Building a scale model of the International Space Station — using matchsticks!

Building a scale model of the International Space Station — using matchsticks!

Recently completed by Acton, the wooden ISS is as impressive in size as it is in detail. Comprised of 282,000 matchsticks, the 1/26 scale model required 8 gal (30 L) of glue and took roughly 1,950 hours to complete. Whereas the actual ISS measures out at 108.5 m (356 ft) wide and 72.8 m (239 ft) long, Acton’s scaled down version measures out at an impressive 4.1 m (13.5 ft) and 2.8 m (9.2 ft) wide. Solar arrays, trusses, communication components, and even the Space Shuttle Atlantis, are all there in intricate detail.

With pictures.

Fact checking Elon Musk’s statements about his company’s efforts to reuse the Falcon 9 first stage reminds us of some space history and one of Musk’s chief competitors.

Fact checking Elon Musk’s statements about his company’s efforts to reuse the Falcon 9 first stage reminds us of some space history and one of Musk’s chief competitors.

The bottom line: Bringing the first stage back to Earth safely and vertically is doable, and has been done before.

In response to the Obama administration’s request a judge has lifted her injunction against the purchase of Russian rocket engines for the Atlas 5 rocket.

In response to the Obama administration’s request a judge has lifted her injunction against the purchase of Russian rocket engines for the Atlas 5 rocket.

More here. It appears that, at least for the moment, the Atlas 5 rocket will be allowed to buy these engines. Whether the Russians will continue to allow them to buy them however remains an open question, especially if things in the Ukraine get worse.

Less than 24 hours after the House held Lois Lerner in contempt, the IRS has finally agreed to turn over all her emails to House investigators.

2:31 pm

Less than 24 hours after the House held Lois Lerner in contempt, the IRS has finally agreed to turn over all her emails to House investigators.

Republican lawmakers have been demanding the documents for months and, in March, Oversight Committee chairman Darrell Issa threatened to hold IRS commissioner John Koskinen in contempt if he did not produce the e-mails requested by the committee. Koskinen had told lawmakers it might take years to produce them. [emphasis mine]

Years, eh? That’s suddenly changed, hasn’t it?

How to turn an American spacecraft ferrying astronauts to ISS serve as a lifeboat as well.

How to turn an American spacecraft ferrying astronauts to ISS serve as a lifeboat as well.

A very interesting read, as it outlines the specific technical problems faced by engineers that one wouldn’t normally consider. The capsule has to be able to remain functional and reliable after months in orbit, but it also has to become functional at a moment’s notice, should an emergency happen.

The creation in the lab of an as yet unnamed superheavy element adds weight to the theory that there might exist even heavier elements that are stable in nature.

8:59 am

The creation in the lab of an as yet unnamed superheavy element adds weight to the theory that there might exist even heavier elements that are stable in nature.

The scientists did not observe element 117 directly. Instead, they searched for its daughter products after it radioactively decayed by emitting alpha particles—helium nuclei with two protons and two neutrons. “The heavy nuclei makes an alpha decay to produce element 115, and this also decays by alpha decay,” says Jadambaa Khuyagbaatar of GSI, lead author of a paper reporting the results published on 1 May in Physical Review Letters.

After a few more steps in this decay chain, one of the nuclei produced is the isotope lawrencium 266—a nucleus with 103 protons and 163 neutrons that had never been seen before. Previously known isotopes of lawrencium have fewer neutrons, and are less stable. This novel species, however, has an astonishingly long half-life of 11 hours, making it one of the longest-lived superheavy isotopes known to date. “Perhaps we are at the shore of the island of stability,” Düllmann says.

If these superheavy elements could be created, they would be the stuff of science fiction. They might have properties that we would find extremely useful.

The IRS audited 10 percent of all Tea Party donors, a rate much higher than for average Americans.

9:52 pm

Working for the Democratic Party: The IRS audited 10 percent of all Tea Party donors, a rate much higher than for average Americans.

Republicans said 24 conservative groups were asked for their donor lists. The IRS initially told Congress that those lists were destroyed, but when they went through their files they discovered three lists that weren’t destroyed.

Rep. Dave Camp, Michigan Republican and chairman of the House Ways and Means Committee, asked the IRS to review the names on those lists to see whether any had been audited. The IRS reported back that 10 percent were audited — substantially higher than the average rate of 1 percent of average Americans who are audited each year.

In other words, the IRS acted as an agent of the Democratic Party to harass and strike fear into their opponents.

According to a GAO report, the sequester cuts that were going to destroy civilization as we know it resulted in exactly one layoff across the entire federal government.

According to a GAO report, the sequester cuts that were going to destroy civilization as we know it resulted in exactly one layoff across the entire federal government.

That is not a typo. Only one person total was laid off to meet the mandated cuts imposed by sequestration. Most agencies froze hiring or imposed furloughs, though even the number of furloughs was less than predicted.

Remember this fact the next time a politician screams dire warnings about any cuts in the federal budget.

Obama administration officials from three departments have asked a federal judge to lift her injunction against Lockheed Martin’s use of Russian engines in its Atlas 5 rocket.

Obama administration officials from three departments have asked a federal judge to lift her injunction against Lockheed Martin’s use of Russian engines in its Atlas 5 rocket.

Not much teeth in these sanctions imposed by the Obama administration, is there? They exempt ISS, which is the bulk of NASA’s effort with the Russians. Now they wish to exempt the Atlas 5. Pretty soon I expect them to exempt almost everything else.

Putin and the Russians are certainly watching this story unfold, and will use what happens here to help gauge how much they can get away with in the Ukraine. And based on some fascinating information conveyed by a caller to my appearance last night on the Space Show, the Russians are definitely going to have to grab more of the Ukraine to make their capture of the Crimea stick. Expect that situation to remain very hot for the near future.

I will again be discussing this subject in depth tonight on Coast to Coast with George Noory.

SpaceX continues to acquire land in Texas for its planned spaceport in Brownsville.

8:40 am

The competition heats up: SpaceX continues to acquire land in Texas for its planned spaceport in Brownsville.

Elon Musk’s Dogleg Park LLC picked up an additional five lots in late April, bringing the total number of lots it has acquired in Cameron County to 95. The total land area that SpaceX now owns is roughly 38 acres of land, public records show. This is in addition to 56.5 acres that SpaceX has under lease at the site of what would be the world’s first private and commercial vertical launch site.

Compared to the acquisitions made by the federal government when it established its space centers in Florida and Wallops Island, these purchases are small. Nonetheless, they are likely sufficient for what the company plans to do.

SpaceX releases spectacular footage of another vertical take-off and landing test of their Falcon 9R rocket.

8:33 am

The competition heats up: SpaceX releases spectacular footage of another vertical take-off and landing test of their Falcon 9R rocket, this time flying over 3,000 feet in the air.

Video below the fold. What I think everyone, including me, has missed so far about both the Grasshopper and the Falcon 9R test flights is that the test vehicle not only was able to land safely using its rockets, both vehicles were quickly turned around and flown again. This certainly lends weight to the feasibility of the company’s plan to make their first stage reusable.

It turns out that the object dubbed G2 that is zipping past the Milky Way’s central black hole is behaving not like a cloud but more like a star.

10:24 pm

The uncertainty of science: It turns out that the object dubbed G2 that is zipping past the Milky Way’s central black hole is behaving not like a cloud but more like a star.

The latest observations by the Keck Observatory in Hawaii show that the gas cloud called “G2” was surprisingly still intact, even during its closest approach to the supermassive black hole at the center of our Milky Way galaxy. Astronomers from the UCLA Galactic Center Group reported today that observations obtained on March 19 and 20, 2014 show the object’s density was still “robust” enough to be detected. This means G2 is not just a gas cloud, but likely has a star inside.

When I wrote a piece about this object for Sky & Telescope I found that among astronomers there was great skepticism about it being just a gas cloud that would be ripped apart when it flew past the black hole. The early data was not conclusive, but enough of it suggested G2 was a star, not a cloud. It turns out here that the skeptics were right.

The porksters arrive!

9:01 am

A draft bill in Congress is proposing the Pentagon develop an engine for the Atlas 5 engine to replace the Russian engine now used.

The legislation passed by a House subcommittee Wednesday calls for up the U.S. military to spend up to $220 million next year to kick off full-scale development of the engine, which could be ready for flights no later than 2019. The bill states the Defense Department “should develop a next-generation liquid rocket engine that is made in the United States, meets the requirements of the national security space community, is developed by not later than 2019, is developed using full and open competition, and is available for purchase by all space launch providers of the United States.”

There is no reason for this funding gift to the aerospace industry. For one thing, there are two rockets that already exist that use all U.S. parts, the Delta family of rockets and the Falcon 9. For another, if Congress stays out, the private sector will take care of this need and do it for a lot less and far quicker, while costing the taxpayers relatively little. By making this a government project we guarantee it will be expensive and take forever, thus keeping the pork flowing to Congressional districts without solving the problem.

And speaking of keeping pork flowing to Congressional districts, pork king Senator Richard Shelby (R-Alabama) today ripped into NASA for trying to trim a little from the budget of SLS (which sends a lot of cash to Alabama). He also condemned NASA’s manned commercial effort.

In addition to my May 6 at 7 pm (Pacific) appearance on the Space Show with David Livingston to discuss the situation with the Russians and ISS, I am also going to appear on Coast to Coast with George Noory on May 7 from 10 to 11 pm (Pacific) to discuss the same topic.

The Russian situation is a difficult one for the United States, and the reason it is difficult is because of a long series of incredibly stupid decisions by our elected officials, from both parties, for the past decade. Nor is my complaint here 20-20 hindsight. From the day George Bush proposed retiring the shuttle in 2010 and not replacing it until 2014, at the earliest, I have said this is stupid and astonishingly short-sighted. Sadly, Congress liked Bush’s short-sightedness and has been endorsing it now for a decade. Hearing them complain now about our dependence on Russian space capabilities is more than infuriating. Where were they when they might have done something to prevent this situation?

Listen in. I think it will be entertaining.

“Obama’s 3-Part Benghazi strategy: Lie, lie, and lie again.”

“Obama’s 3-Part Benghazi strategy: Lie, lie, and lie again.”

I haven’t posted much on Benghazi, but even a nonchalant read of the subject reveals the same pattern of blatant lies from the Obama administration as we saw with his promise that “If you like your healthplan you can keep it.” Why anyone with any intelligence trusts anything this administration says is beyond me.

Iowa City police seized $48K in cash from a Minnesota couple during a traffic stop in March and now refuse to return it.

9:49 am

Theft by government: Iowa City police seized $48K in cash from a Minnesota couple during a traffic stop in March and now refuse to return it.

The publication says Kearnice C. Overton, of St. Paul, was pulled over March 16 for speeding. Overton’s kids were in the car at the time. Police say a K-9 signal gave them the authority to search the car, the Press-Citizen reports. So they did, found the $48,000 in cash, and seized it.

Overton says he got the money from his wife, Tiffani D.S. Barber, to buy some property in Iowa; he drove down there, the deal fell through so he was on his way home. Barber and Overton filed a petition stating the money was wrongly seized – no charges were filed, Overton was not arrested, and he claims it wasn’t illegally earned – and they want it back, the Press-Citizen reports. [emphasis mine]

So, police can take your money, even if you broke no law, and keep it. A good deal, especially since there is no one around to arrest them for theft.
