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.

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.

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.

For the first time astronomers think they have measured the rotation rate of an exoplanet, thus determining the length of its day.

For the first time astronomers think they have measured the rotation rate of an exoplanet, thus determining the length of its day.

Ignas Snellen and his colleagues at Leiden University in the Netherlands report in Nature1 that a gaseous planet orbiting the star β Pictoris rotates at 25 kilometres per second at its equator — faster than any planet in the Solar System and about 50 times faster than Earth. A day on the planet, called β Pictoris b, lasts just over eight hours, even though the planet has a diameter more than 16 times that of Earth’s and carries more than 3,000 times Earth’s heft.

This result falls under my category of “the uncertainty of science.” Though quite cool, and based on real data, the uncertainties are great. Don’t bet the house that this result will stand up to closer observations in the future.

Engineers commanded Curiosity to drill its third drill hole on Tuesday on what looks like an outcrop of sandstone in Gale Crater.

Engineers commanded Curiosity to drill its third drill hole on Tuesday on what looks like an outcrop of sandstone in Gale Crater.

This hole is shallow and is merely a test to see if a deeper full bore would be worthwhile geological.

That Curiosity has only drilled three holes, and is now only doing a test bore first is partly because engineers fear that using the drill too much will cause a short circuit that will disable the rover entirely. This fear is because of a design flaw in the construction of the rover and the drill.

A gigantic forest fire threatens Russia’s new spaceport under construction in Vostochny.

A gigantic forest fire threatens Russia’s new spaceport under construction in Vostochny.

[Spaceport construction chief Konstantin] Chmarov reportedly characterized the fire-fighting effort in the region as “chaos.” Fueled by hot weather and strong winds, the fire approached the airport in Svobodny and was also moving toward Vostochny. In the meantime, satellite images showed heavy smoke blanketing the future space center.

The Putin government has been giving the completion of this spaceport a high priority. Having it burn down before completion is not what they want.

SpaceX has won an injunction from a federal judge, preventing ULA from buying any further Russian engines.

9:03 am

SpaceX has won an injunction from a federal judge, preventing ULA from buying any further Russian engines.

Federal Claims Court Judge Susan Braden said her preliminary injunction was warranted because of the possibility that United Launch Alliance’s purchase of Russian-made engines might run afoul of the sanctions. NBC News’ past coverage of the issue was cited in Braden’s ruling.

Wednesday’s injunction prohibits any future purchases or payments by the Air Force or United Launch Alliance to NPO Energomash, unless and until the Treasury Department or the Commerce Department determines that the deal doesn’t run counter to the U.S. sanctions against Russian officials. Braden stressed that her ruling does not affect previous payments to the Russians, or purchase orders that have already been placed. United Launch Alliance says it already has some of the engines on hand.

This injunction is not directed specifically at the Air Force’s bulk buy from ULA, nor does it address the cartel-like nature of the ULA monopoly for Air Force launches that SpaceX is challenging. However, it does put a serious crimp, if temporary, on the use of Lockheed Martin’s Atlas 5 rocket, which depends on the engine for all its launches. Though the company has engines in stock, they will quickly run out with no way to immediately replace them.

I will be making a special appearance on the Space Show this coming Tuesday, May 6, at 7 pm (Pacific) to discuss at length how the political friction between the United States and Russia over the Ukraine might impact the situation at ISS.

Should be quite fun. Feel free to tune in and to call in questions.

Orbital Sciences is considering using ATK’s solid rocket motors to replace the refurbished Russian engines in the first stage of its Antares rocket.

Orbital Sciences is considering using ATK’s solid rocket motors to replace the refurbished Russian engines in the first stage of its Antares rocket.

This helps explain the merger between the two companies, as it gives Orbital control over the equipment it needs to keep Antares viable. More important, it also could make it entirely American made, which will be attractive to both Congress and many U.S. commercial satellite companies.

Senate Democrats plan a vote to amend the First Amendment to curtail criticism.

10:57 am

Fascists: Senate Democrats plan a vote to amend the First Amendment to curtail criticism.

Think of the big issues facing the American public. We now routinely borrow about 40 cents on the dollar for our federal budget, our entitlement programs are heading for a fiscal collapse in the hundreds of trillions of dollars, and our economy has stagnated through nearly five years of Democratic-run economic policy in the “recovery.” What do Senate Democrats plan to do about this? Make it harder for us to complain about it.

The text of the amendment specifically gives Congress the power to limit the right of citizens to support the candidates of their choice. Who thinks they won’t abuse that power, should they get it?

This year saw the biggest increase in healthcare spending in thirty years.

9:48 am

Finding out what’s in it: This year saw the biggest increase in healthcare spending in thirty years.

The cause is undeniably Obamacare, but whether the increase is good or bad can be argued. Supporters of Obamacare (few as they are) would say that this is because of the increased demand for healthcare and larger customer base that Obamacare mandated. Opponents (like me) would agree, but add that the increases are impractical, unrealistic, and raise prices unnecessarily. Many of these new unwilling customers are being forced to buy a product they don’t need.

More delays seen in the completion of a new and critical module to the Russian portion of ISS.

More delays seen in the completion of a new and critical module to the Russian portion of ISS.

The delays have nothing to do with the Ukraine and everything to do with poor quality control in the Russian company building the module.

This quote stood out however:

With its central position in the architecture of the Russian segment, the MLM’s troubles also stall the launch of all subsequent Russian components of the station, including the Node Module, UM, (already under construction) and the NEM laboratory and power supply module, whose full-scale development started in 2012.

Given such a prolonged delay, combined with worsening political relations between Russia and its partners in the ISS project, the questions were raised whether the MLM module and the successive components of the Russian segment could be grounded until the assembly of the new all-Russian station in the post-ISS era. Under such a scenario, the troubled spacecraft could play a role of an early hub for the future orbital outpost.

If the Russians get enough modules built to launch their own station, I expect them to do it and cut their ties with ISS.

SpaceX has released video of its Falcon 9 first stage splashing down vertically in the ocean.

SpaceX has released video of its Falcon 9 first stage splashing down vertically in the ocean.

The video is not very good, but at one point you can clearly see for a flash that the first stage is vertical and appears to be hovering above the water.

For decades engineers and managers in the aerospace industry have said that returning a first stage vertically made no sense. Elon Musk insisted that SpaceX try. It appears he and his company are now going to prove that everyone else was wrong about this.

A doctor’s declaration of independence.

A doctor’s declaration of independence.

I don’t know about other physicians but I am tired—tired of the mandates, tired of outside interference, tired of anything that unnecessarily interferes with the way I practice medicine. No other profession would put up with this kind of scrutiny and coercion from outside forces. The legal profession would not. The labor unions would not. We as physicians continue to plod along and take care of our patients while those on the outside continue to intrude and interfere with the practice of medicine.

We could change the paradigm. We could as a group elect not to take any insurance, not to accept Medicare—many doctors are already taking these steps—and not to roll over time and time again. We have let nearly everyone trespass on the practice of medicine. Are we better for it? Has it improved quality? Do we have more of a voice at the table or less? Are we as physicians happier or more disgruntled then two years ago? Five years ago? Ten years ago?

Russia responds to new U.S. sanctions by threatening U.S. astronauts on ISS.

10:06 am

Uh-oh: Russia responds to new U.S. sanctions by threatening U.S. astronauts on ISS.

Moscow reacted with fury to the inclusion in the sanctions of high-tech exports to Russia and threatened reprisals. “If their aim is to deliver a blow to Russia’s rocket-building sector, then by default, they would be exposing their astronauts on the ISS,” Russian Deputy Prime Minister Dmitry Rogozin said, according to the Interfax news agency.

“Sanctions are always a boomerang which come back and painfully hit those who launched them,” added Rogozin on a visit to Crimea, which Russia annexed from Ukraine in March. [emphasis mine]

Was Rogozin actually hinting that Russia might strand U.S. astronauts on ISS?

ATK is splitting off its aerospace division to merge that division with Orbital Sciences.

9:27 am

The competition cools? ATK is splitting off its aerospace division to merge that division with Orbital Sciences.

Alliant Techsystems Inc. ATK on Tuesday said it plans to split into two independent companies, one focused on outdoor sports and hunting products, the other centered on aerospace and defense. The outdoor sports operations–which produce commercial ammunition, hunting products and other related items–will be spun off to Alliant shareholders in a tax-free transaction, the company said. The segment generated $2.2 billion in revenue during 2013, Alliant said.

After the separation, Alliant said it plans to merge the aerospace and defense business–which produces rocket propulsion systems and satellite systems, among other things–with rocket and space-system developer Orbital Sciences Inc. The company will be named Orbital ATK Inc.

More here. The company press releases call this “a merger of equals” and do not make it clear what instigated the deal. Did Orbital offer to buy ATK’s aerospace division with its ammo business spun off, or did ATK want to sell off its aerospace division to focus on ammo? I wonder. The ammo business right now is booming, while aerospace remains a much more risky venture. ATK might have wanted to focus on ammo, where the money is, and proposed the idea to Orbital.

Arianespace today scrubbed the third launch of its new Vega rocket at T-minus 10 minutes due to a technical problem.

The reliability of Arianespace’s rockets has always been the company’s big selling point, so a launch scrub is very unusual for them. Then again, this is only the third launch of Vega, so we shouldn’t be surprised if they are still working out the kinks.

A proposed House bill would forbid use of Russian rocket engines in launching any American military payloads.

4:52 pm

A proposed House bill would forbid use of Russian rocket engines in launching any American military payloads.

This bill is being put forth partly because of the Ukrainian situation and partly to support SpaceX’s effort to break the ULA Atlas/Delta monopoly on military launches. Whether it makes any sense or not is of course beside the point.

Meanwhile, the State Department has expanded the sanctions on satellite exports to Russia, which might threaten some future commercial Proton launches.

Both actions suggest that Elon Musk’s political clout is growing. Obviously his company’s concerns are not the prime motivation behind these decisions, but we should note that both actions hurt his direct competitors, while doing little harm to SpaceX.

ULA has accelerated delivery of its required Russian rocket engines in anticipation of worsening relations with Russia and with members of Congress.

8:53 am

The competition heats up: ULA has accelerated delivery of its required Russian rocket engines in anticipation of worsening relations with Russia and with members of Congress.

ULA presently is the only company the Air Force uses to launch its military satellites, and members of Congress are questioning this monopoly in the context of the situation in the Ukraine as well as SpaceX’s lawsuit challenging it.
