Yutu still operational after two years

8:15 am

Despite an inability to move, China’s rover Yutu has now set the longevity operational record for rover on the Moon.

Yutu was deployed and landed on the moon via China’s Chang’e-3 lunar probe in 2013, staying longer than the Soviet Union’s 1970 moon rover Lunokhod 1, which spent 11 months on the moon. Its operations have streamed live through Sina Weibo, a Chinese microblogging site, and its Weibo account has nearly 600,000 followers.

Yutu experienced a mechanical control abnormality in 2014, but it was revived within a month and, though it is unable to move, it continues to collect data, send and receive signals, and record images and video.

Oxygen in Comet 67P/C-G coma

8:38 am

The uncertainty of science: Unexpectedly scientists using Rosetta data have discovered oxygen in the coma of Comet 67P/C-G.

It was not immediately clear where the oxygen came from. The team discovered that water and oxygen were often found together — an indication that similar processes released both molecules. But Bieler and his colleagues ruled out many scenarios in which oxygen arises as a by-product when energetic particles such as photons and electrons split apart water. Instead, the researchers argue that the oxygen is a remnant from when 67P formed billions of years ago, a process that may have trapped the gas in small grains of ice and rock that coalesced to create the comet’s solid core.

But many models of the early Solar System rule this out because most oxygen tends to pair off with hydrogen. Given this affinity, it is tricky to adjust models of the early Solar System to allow for the survival of gaseous O2, says Mike A’Hearn, an astronomer at the University of Maryland in College Park and a co-investigator on Alice. But he adds that it may be possible with the right chemical abundances and temperature conditions.

45 Republicans vote against Paul Ryan nomination

3:04 pm

The Republicans have nominated Paul Ryan (R-Wisconsin) for Speaker of the House with only 200 of 245 votes.

Those 45 members are enough to block him from getting the Speakership during the partisan floor vote on Thursday — if the 45 GOP legislators maintain their opposition, and if Ryan is not aided by a last-minute bloc of Democratic votes.

During the closed-door conference, Ryan won just 200 votes for the nomination. Former Florida House Speaker Rep. Daniel Webster (R-FL) earned a whopping 43 votes. Rep. Marsha Blackburn (R-TN) — who isn’t officially running for Speaker — received one vote. House Majority Leader Rep. Kevin McCarthy (R-CA), who dropped out of the Speakership race a couple weeks ago, got one vote as well.

The failure on Ryan’s part to win 218 votes—the threshold for anyone to win the Speakership on the House floor assuming every member of the House is present and voting for a person—is a major embarrassment on his part.

If those who opposed Ryan in this Republican vote maintain that opposition when the whole House votes, the only way Ryan can become Speaker is if he gets Democratic votes. If that happens than either he won’t become Speaker or the Republican Party faces a breakup.

Based on recent events with the budget deal, it might make sense for some of these fake conservatives in the Republican Party to admit their real loyalty and join the Democrats. The conservatives would then probably lose control of Congress, but at least we would know where people honestly stood.

A mother and father is still the best for kids

2:14 pm

Science discovers the obvious: Several new studies have found again that children generally do better in a stable family with a mother and a father than in any other combination.

In recent weeks, a barrage of new evidence has come to light demonstrating what was once common sense. “Family structure matters” (in the words of my American Enterprise Institute colleague Brad Wilcox, who is also the director of the National Marriage Project at the University of Virginia). Princeton University and the left-of-center Brookings Institution released a study that reported “most scholars now agree that children raised by two biological parents in a stable marriage do better than children in other family forms across a wide range of outcomes.” Why this is so is still hotly contested.

Another study, co-authored by Wilcox, found that states with more married parents do better on a broad range of economic indicators, including upward mobility for poor children and lower rates of child poverty. On most economic indicators, the Washington Post summarized, “the share of parents who are married in a state is a better predictor of that state’s economic health than the racial composition and educational attainment of the state’s residents.”

I think it amusing that some scientists wonder “why this is so.” I also realize that by stating this obvious fact of nature I and these scientists are being racist homophobes who want to oppress minorities, but who am I to argue with reality?

Another Obamacare co-op fails

10:14 am

Finding out what’s in it: Utah’s only Obamacare co-op has announced it is shutting down at the end of the year due to lack of funding/income.

Arches, the only co-op health plan in Utah, began offering insurance through the Affordable Care Act in fall 2013, beginning coverage in January 2014. The nonprofit group says it’s ceasing operations because of a lack of funding from the federal “risk corridor” program, which was built into the Affordable Care Act and intended to protect insurance companies from their losses. “As one of the carriers on the (health care) exchange, we stood to benefit by our calculations in excess of $30 million for those ‘risk corridor’ payments,” Tricia Schumann, chief marketing and communications officer for Arches, told KSL. “We did anticipate those cash payments coming in … this quarter.”

The point of the fund was to mitigate losses among insurance companies and co-ops that suffered large financial risk associated with the Affordable Care Act because of unprecedented enrollment for coverage.

However, federal officials announced Oct. 1 that only 12.6 percent of the expected windfall from that risk management fund would be awarded to insurance companies.

In other words, they — and Obamacare — never had a viable profit model (as predicted by conservatives even before the law was passed). Instead, they were depending on large federal government handouts, as mandated by Obamacare itself. The federal government however simply can’t afford to give out that much money, and thus, bankruptcy.

All the more reason to continue to vote Democrat! They cared, even though they hadn’t the slightest idea of what they were doing and thus pushed through a law that was incredibly stupid and damaging. That they cared however is all that matters.

Ryan to support budget deal

9:57 am

The fix is in: House Speaker-to-be Paul Ryan (R-Wisconsin) announced today that he will support the two year budget deal worked out by the White House and Republican and Democratic leaders that locks in increased spending and raises the debt limit for the next two years.

I could also say that Ryan’s betrayal of the conservatives in Congress didn’t take long. He didn’t even wait until he was officially elected Speaker. And if you read his reasons for this decision at the link, you will see them for what they are, shallow talking points that mean nothing.

The only good thing about this is — and it isn’t much — is that it will likely provide Ted Cruz some nice ammunition during tonight’s Presidential debate.

That the Freedom Caucus in the House is pissed at the deal and will oppose it also suggests to me that we are getting closer and closer to a split in the Republican Party.

Get 2 out of 10 questions right and pass!

9:41 am

The coming dark age: A California school district has instituted a new grading scale that allows students to pass with a score of only 20 out of 100.

Some teachers have tried to hang on to the traditional grading system but have been tripped up by a blanket new policy that students, even if they do not hand in homework or take a test, get 50 percent. Under the new rule, it’s possible for a student who skips a test to receive a better grade than a student who takes the test and does poorly. “This is just incomprehensible. I don’t have words,” said Lanny Lowery, who has taught English at Rancho Cotate High since 1980

And then there’s this: NYC schools passing failing students, colleges accepting them.

In other words, you can now graduate having learned absolutely nothing. Should make for an interesting future for the student and the society that student helps shape.

Comet 67P/C-G has passed peak brightness

9:31 am

Using both ground-based and Rosetta observations scientists have now measured when the comet reached its peak brightness as well as how much material it lost during this orbit’s closest approach to the Sun.

Based on Rosetta’s pre-perihelion measurements that indicate the dust:gas ratio was approximately 4 , that means roughly 80% of the material being lost is dust, with the rest dominated by water, CO, and CO2 ices. (Note: at the time of that blog post an estimate of 3 was made for perihelion, but the actual data has yet to be analysed.) In any case, using 3 and 4 respectively, the total mass loss rate at its peak is likely in the range of about 100,000–115,000 tonnes per day.

Of course, that’s not a huge amount compared to the comet’s overall mass of around 10 billion tonnes. But nevertheless, a very simple calculation reveals that if, for example, the comet lost that much mass continuously for 100 days, it would correspond to roughly 0.4-0.5 metres of its surface being removed in that time.

In other words, the surface lost about 1.5 feet during close approach.

Peak brightness occurred near the end of August, and has been declining since.

Russia’s ten-year space policy delayed again

9:22 am

The competition heats up: The completion of Russia’s much delayed ten-year space policy plan, originally planned for last year and then planned for November, has likely been delayed again.

The program was supposed to be submitted to the government for approval late last year, but the collapse of the ruble, ongoing launch failures and related mishaps, leadership shakeups at the federal space agency, and an industry-wide reform plan have all conspired to delay the final draft. A draft was expected this summer, but in March a senior Roscosmos official was quoted by the TASS news agency as saying that the proposal had already been significantly altered, and “looks completely different” than it did when originally completed in 2014. The biggest change to the draft was the level of funding dedicated to Russian space exploration over the 10-year period from 2016 to 2025, which was reduced by 10 percent between drafts to 3.4 trillion rubles ($52.5 billion).

Just like the Soviet era’s many repeated five-year plans, expect the goals of this policy statement, once announced, to fail repeatedly. They will have some initial success, but in the end this top-down government program, like NASA’s SLS, will have more to do with creating non-productive jobs than actually building spaceships and rockets.

ULA shuffles and trims its executive leadership

9:11 am

The competition heats up: In its effort to improve its efficiency and lower costs, ULA shuffled and reduced the size of its executive team.

All these changes are under the leadership of the company’s CEO Tory Bruno, who took over in 2014 with the goal of cutting what company charges for a launch while speeding up its launch prep times. The effort to launch three Atlas 5s in this month is clearly the result of this policy.

Early Apollo rover prototype sold for scrap

9:00 am

An early test prototype of the Apollo lunar rovers, apparently parked in an Alabama backyard for decades, was sold for scrap and lost when the estate of its owner was liquidated.

“It has come to the attention of the Marshall Space Flight Center historian that you may be in the possession of a prototype of a Lunar Roving Vehicle,” NASA wrote to the buggy’s owner in an August 2014 letter requesting that the LRV be turned over. “Returning the vehicle to the Marshall Space Flight Center would allow MSFC to restore [it] so it might be used for historical and educational purposes.”

Unfortunately, the letter arrived too late. “Upon contacting the current owner,” NASA’s Office of the Inspector General reported in December, “we learned the LRV had been sold for scrap after [redacted] had passed away.”

Buy the first computer to fly in space!

8:51 am

The first digital RAM computer memory chip to fly in space is up for auction and you can buy it.

As part of its Space Exploration Signature Auction, Heritage Auctions is taking bids for a vintage random access, non-destructive readout 4,096 bit memory plane that flew on Gemini 3. This ferric memory unit was an integral part of the Gemini Spacecraft Computer, which was the first computer installed in a manned space capsule.

Gemini 3 was the first manned Gemini mission and completed 3 orbits on March 23, 1965. The auction goes through November 3, and bidding is presently at $2,000.

Dawn begins descent to final orbit around Ceres

8:33 pm

Engineers have fired up Dawn’s ion engine and have begun lowering the spacecraft’s orbit downward.

The spacecraft is now on its way to the final orbit of the mission, called the low-altitude mapping orbit. Dawn will spend more than seven weeks descending to this vantage point, which will be less than 235 miles (380 kilometers) from the surface of Ceres. In mid-December, Dawn will begin taking observations from this orbit, including images at a resolution of 120 feet (35 meters) per pixel.

They’ve also released a nice mosaic showing the double bright spots in Occator Crater as well as the surrounding terrain.

The Okinawa missiles of October

11:42 pm

Though the story is not confirmed, it appears that in 1962 the Air Force base at Okinawa came mere seconds from launching its nuclear missiles during the Cuban missile crisis.

The most frightening part of the story is this:

According to Bordne’s account—which, recall, is based on hearing just one side of a phone call—the situation of one launch crew was particularly stark: All its targets were in Russia. Its launch officer, a lieutenant, did not acknowledge the authority of the senior field officer—i.e. Capt. Bassett—to override the now-repeated order of the major. The second launch officer at that site reported to Bassett that the lieutenant had ordered his crew to proceed with the launch of its missiles! Bassett immediately ordered the other launch officer, as Bordne remembers it, “to send two airmen over with weapons and shoot the [lieutenant] if he tries to launch without [either] verbal authorization from the ‘senior officer in the field’ or the upgrade to DEFCON 1 by Missile Operations Center.”

Read it all. Quite fascinating, and chilling. A hat tip to Shane Rollin, my web guy, for sending this to me.

Lockheed Martin ready to build Orion?

6:08 pm

O joy! After more than a decade of design work, costing billions, Lockheed Martin now says it is ready to begin building the first Orion capsule for eventual launch only 8 years from now!

“The vast majority of Orion’s design is over, and now we will only change things when new requirements come into play,” said Michael Hawes, Lockheed Martin Orion vice president and program manager. “Considering the incredible complexity of this spacecraft, the team is very proud to have successfully completed the design review and is looking forward to seeing it fly.”

For those who don’t detect my sarcasm, I find this project more than absurd. Bush proposed Orion in 2004. Lockheed has been spending billions for years just designing it. In about six to eight years from now they might finally get one capsule completed for launch in 2023, almost two decades after it was first proposed.

Two decades to build one capsule! With a cost in the billions. Let these facts sink in for a bit and then ask yourself: Why are we spending money on this pork project that will never fly?

Worldview tests subscale prototype of its balloon and capsule

5:59 pm

The competition heats up: Worldview, the company planning to sell tickets for high-altitude tourist flights to the edge of space, successfully completed this weekend a test flight of a 10-percent scale prototype of its capsule and balloon.

The balloon reached an altitude just over 100,000 feet, just under 19 miles. The capsule then separated and landed safely using a parafoil. This success keeps them on schedule for their first commercial flights in 2017.

Congressional leaders negotiating 2-year spending deal

10:48 am

The fix is in: The White House and Republican and Democratic Congressional leaders hope to complete a two year budget deal by tonight that will allow an increase in the debt limit.

White House budget director Shaun Donovan and legislative affairs director Katie Beirne Fallon are hammering out the package with staff representing Senate Majority Leader Mitch McConnell (R-Ky.), Speaker John Boehner (R-Ohio), Senate Democratic Leader Harry Reid (Nev.) and House Democratic Leader Nancy Pelosi (Calif.). House Ways and Means Chairman Paul Ryan (R-Wis.) is expected to be elected Speaker on Thursday, but he has not taken part in these budget negotiations, aides said. In recent weeks, Boehner has said he wants to “clean the barn up a little bit” before he leaves Congress at the end of the week.

Legislation to raise the debt ceiling and fund the government is central to the deal, but the talks are also said to include measures that would fund highway and infrastructure construction and renew the Export-Import Bank for one year.  

If you read the article with a clear mind, you will see that all the dealmaking is designed to increase spending. Moreover, it notes how Senate Republican leader Mitch McConnell (R-Kentucky) does not want to have the renewal of the Export-Import Bank on a stand-alone bill. Unstated is why, as he knows that on its own the Republican majorities in both Houses would shoot it down in a second.

When Senator Ted Cruz (R-Texas) refers to these guys as the “Washington cartel” he is exactly right. They have no interest in cutting the size of the federal government, and are doing whatever they can to maintain their steadily weakening grip on power. The good news is that their grip is weakening.

Billions of Obamacare funds pocketed by Democrats

9:17 am

Finding out what’s in it (for Democrats): Billions of dollars of Obamacare funds have vanished, having been given to sixteen states — mostly Democratically-run — to build Obamacare marketplaces but never used as intended.

The controls on federal spending right now are nil. The money almost goes out randomly, without any scrutiny, funding the friends of the Washington politicians both in Washington and throughout the country. The Democrats might have benefited royally from Obamacare, but the Republican leadership gets its own payoffs with these funds, which is why they haven’t done much to cut spending, even though that was the promise they ran under.

Pluto’s meandering canyons

8:52 am

canyons of Pluto

Cool image time! In scrolling through the new raw images downloaded from New Horizons today I came across an image, one of several, that showed what clearly appeared to be meandering canyons carved by flowing liquid.

To show it here, I have cropped it and reduced its size somewhat, highlighting the most interesting features. As you can see, the largest canyon not only appears to have a dark floor, it cuts right through an older crater. Smaller canyons do the same thing. In addition, many of the craters seem to be ponded with the same dark material that floors the canyons, while some of the smaller canyons show tributaries that come together, just like rivers. Are these flows of liquid nitrogen?

I eagerly await the conclusions of the scientists, who are probably only slightly less baffled by these features as I am.

Be sure and check out the full image, as well as the other raw images. The data continue to come in from New Horizons, but the science team is no longer under the same kind of public pressure to make announcements or hold press conferences. There are gems hidden there that are worth looking at, even if they are not as yet accompanied by any scientific analysis.

NASA to decide on 2nd cargo contracts Nov 5

9:40 am

The competition heats up: NASA will announce the two contract winners for its second round of ISS cargo contracts on November 5.

If it was up to me to pick the two winners from the four companies bidding, SpaceX, Boeing, Orbital ATK, and Sierra Nevada, I would go with Orbital ATK and Sierra Nevada. SpaceX and Boeing already have contracts to ferry crews to ISS with their Dragon and Starliner capsules. By picking Orbital ATK’s Cygnus capsule and Sierra Nevada’s Dream Chaser reusable mini-shuttle, NASA would then have four different ways to get payloads to ISS.

Sadly, the decision is not up to me. It is more likely NASA will pick SpaceX and Boeing. Boeing especially is likely to get picked because they are an established big player with lots of capital and influence.
