Orbital ATK cargo contract extended

4:56 pm

The competition heats up: NASA has ordered two more cargo flights from Orbital ATK.

Orbital ATK, Dulles, Virginia, will fly two more missions under its 2008 contract for a total of 10 flights, according to Orbital ATK spokeswoman Vicki Cox. The company designated the missions OA-9e and OA-10e, Cox said. She declined to say when those flights will occur, although the company has said it plans to launch any new CRS missions it gets from NASA on Antares once it completes two deliveries using United Launch Alliance’s Atlas 5 rocket. The Atlas 5 launches are slated for December and early 2016 from Cape Canaveral, Florida.

NASA may also order additional cargo flights from its other CRS contractor, SpaceX of Hawthorne, California. “A modification is in work with both [CRS] providers,” NASA spokeswoman Stephanie Schierholz wrote in an Aug. 13 email. “Additional missions for SpaceX are still under discussion.”

That this contract extension occurs about the same time NASA decided to delay its decision on the second round of cargo contracts is probably not a coincidence. It suggests to me that the agency is probably seriously considering awarding one of the next contracts to a more risky proposal, such as Sierra Nevada’s Dream Chaser. In that case, extending the present contracts gives them some additional margin should the new contractors have problems.

IRS computer hack bigger than previously thought

3:32 pm

Government in action! A hack of IRS taxpayer information was significantly bigger than previously estimated, the IRS revealed today.

An additional 220,000 potential victims had information stolen from an IRS website as part of a sophisticated scheme to use stolen identities to claim fraudulent tax refunds, the IRS said Monday. The revelation more than doubles the total number of potential victims, to 334,000.

Well, no matter, this hack is mere chicken feed compared to the 21 million records stolen from the federal Office of Personal Management. And it hardly compares with the recent Pentagon breach, where the Chinese got almost all federal records. No, the IRS is doing a much better job then those other agencies, only being slightly incompetent and screwing up only a little.

And besides, the IRS does such a good job for Obama by harassing anyone that opposes the Democratic Party agenda! How could anyone complain about them?

Fund-raising campaign to help bakery threatened by gay fascists

10:17 am

Defiance: The Colorado baker who is threatened with bankruptcy and even psychatric evaluation because he refuses to bake same-sex wedding cakes due to his religious beliefs has begun a fund-raising campaign to support his fight.

There are those who think I am being unkind by describing the attackers of this baker as fascists. Well, consider this tidbit from the above story:

He declined to provide a wedding cake for a gay couple in July 2012, citing his Christian beliefs, after which the bakery in Lakewood, Colorado, became the target of protests and angry phone calls. “The calls were so vile, Jack would not allow the employees to answer the phone for weeks. The second day, a caller threatened to kill Jack as well as anyone in the bakery,” said the Continue to Give write-up.

It is important to note that no one is oppressing any homosexuals here. They are still free to practice their lifestyle. The only one being oppressed is the Christian, who is being threatened and denied the right to practice his lifestyle.

“When EPA is not ignoring Supreme Court limitations on it, it is blithely disregarding rule-making laws required of it.”

9:00 am

The story that has the quote above outlines the EPA’s recent and past history of ignoring the law and court rulings to write and impose its regulations. It also details the many times the environmental agency has used its ability to impose fines to extort concessions from private landowners, including the recent Colorado mine disaster.

Like the IRS, the EPA has become an out-of-control agency, a haven for fascists eager to use their power to squelch anyone that opposes them. With the former, this power is used by partisan Democrats to help the Democratic Party and hurt its opponents. With the latter, this power is used to destroy private property rights in the name of leftwing environmental fantasies, even if that use of power ends up doing terrible damage to the environment.

NASA postpones decision again for 2nd ISS cargo contracts

8:44 am

In the heat of competition: NASA has again delayed its decision on awarding its second round of contracts for providing cargo to ISS, delaying the decision from September until November 5.

The launch failures this year is the major reason NASA has held off making a decision. They need to see how both SpaceX and Orbital ATK react to the failures, as both have also bid for second round contracts.

Lumbering the Redwoods

6:01 pm

An evening pause: Tonight’s pause is a challenge. Can you watch this 1940s industrial, describing the lumbering and milling of California redwoods, without feeling outrage or indignation against the work being described? Can you watch it with an open mind, recognizing that trees are renewable?

Or will the environmental brainwashing that our society has undergone since the 1960s cause you to shut your mind and refuse to consider the other side of this story?

Requiring scientists to document their methods caused positive results in medical trials to plunge

9:35 am

The uncertainty of science: The requirement that medical researchers register in detail the methods they intend to use in their clinical trials, both to record their data as well as document their outcomes, caused a significant drop in trials producing positive results.

A 1997 US law mandated the registry’s creation, requiring researchers from 2000 to record their trial methods and outcome measures before collecting data. The study found that in a sample of 55 large trials testing heart-disease treatments, 57% of those published before 2000 reported positive effects from the treatments. But that figure plunged to just 8% in studies that were conducted after 2000. Study author Veronica Irvin, a health scientist at Oregon State University in Corvallis, says this suggests that registering clinical studies is leading to more rigorous research. Writing on his NeuroLogica Blog, neurologist Steven Novella of Yale University in New Haven, Connecticut, called the study “encouraging” but also “a bit frightening” because it casts doubt on previous positive results.

In other words, before they were required to document their methods, research into new drugs or treatments would prove the success of those drugs or treatment more than half the time. Once they had to document their research methods, however, the drugs or treatments being tested almost never worked.

The article also reveals a failure of the medical research community to confirm their earlier positive results:

Following up on these positive-result studies would be interesting, says Brian Nosek, a psychologist at the University of Virginia in Charlottesville and the executive director of the Center for Open Science, who shared the study results on Twitter in a post that has been retweeted nearly 600 times. He said in an interview: “Have they all held up in subsequent research, or are they showing signs of low reproducibility?”

Well duh! It appears the medical research field has forgotten this basic tenet of science: A result has to be proven by a second independent study before you can take it seriously. Instead, they would do one study, get the results they wanted, and then declare success.

The lack of success once others could see their methods suggests strongly that much of the earlier research was simply junk, not to be taken seriously.

NOAA scientists predict developing El Niño could be strongest ever

9:06 am

The uncertainty of science: NOAA scientists yesterday predicted that the developing El Niño in the Pacific could be strongest ever recorded.

They appear to base this prediction on two factors:

It started unusually early — in March instead of June. This could be because warm waters left over from last year’s weak El Niño gave it a head start, says Anthony Barnston, chief forecaster at the International Research Institute for Climate and Society at Columbia University in Palisades, New York.

And this would be the second El Niño year in a row, following the weak El Niño that developed late last year, Barnston adds. A similar El Niño double-header happened between 1986 and 1988, but forecasters predict that the current El Niño will become stronger than either of those two events.

A strong El Niño would help end the drought in California. However, I wouldn’t bet the house on this prediction, considering how poorly last year’s prediction fared. Scientists really don’t yet understand all the factors behind this phenomenon, so their predictions are pretty much guesses at this point.

Astronomers photograph an exoplanet

2:14 pm

51 Eridani b

Cool image time! Astronomers have used the Gemini Telescope on Mauna Kea to take the clearest image yet of a Jupiter-sized gas giant orbiting another star 96 light years away.

Once the astronomers zeroed in on the star, they blocked its light and spotted 51 Eri b orbiting a little farther away from its parent star than Saturn does from the sun. The light from the planet is very faint — more than one million times fainter than its star – but GPI can see it clearly. Observations revealed that it is roughly twice the mass of Jupiter. Other directly imaged planets are five times the mass of Jupiter or more. In addition to being the lowest-mass planet ever imaged, it’s also the coldest — about 800 degrees Fahrenheit — and features the strongest atmospheric methane signal on record. Previous Jupiter-like exoplanets have shown only faint traces of methane, far different from the heavy methane atmospheres of the gas giants in our solar system.

All of these characteristics, the researchers say, point to a planet that is very much what models suggest Jupiter was like in its infancy.

The exoplanet is the bright spot near the bottom of the image.

Cassini’s last fly-by of Dionne on Monday

2:05 pm

Dionne

On Monday August 17 Cassini will make its last close fly-by of Saturn’s moon Dionne, dipping to within 295 miles of the surface.

During the flyby, Cassini’s cameras and spectrometers will get a high-resolution peek at Dione’s north pole at a resolution of only a few feet (or meters). In addition, Cassini’s Composite Infrared Spectrometer instrument will map areas on the icy moon that have unusual thermal anomalies — those regions are especially good at trapping heat. Meanwhile, the mission’s Cosmic Dust Analyzer continues its search for dust particles emitted from Dione.

The image of Dionne above is from a June 16, 2015 fly-by, The diagonal line at the top is Saturn’s rings.

After more than a decade, Cassini’s mission is in its final stages. When completed, we will have no way for decades to get close-up images of this gas giant, its spectacular rings, or its many very different moons.

Obamacare forces schools to cut back

11:30 am

Finding out what’s in it: Public school budgets continue to be squeezed by the cost of Obamacare.

They find they either have to cut employee hours, privatize some services, or eliminate health insurance entirely and pay the Obamacare fines. Otherwise, they can’t afford the costs.

This quote however illustrates the educational cost of Obamacare:

School officials say that it’s hard for students to adjust to having multiple part-time educators throughout the day. Chris Johnson, an administrator with the Penn Manor school district in Pennsylvania, told a publication there that, “If you start doing a half day with this person and then a half day with that person, those students don’t react well.”

Even as it bankrupts us financially, Obamacare is also bankrupting us socially. What a disaster. We desperately need to repeal it, as soon as possible.

The wild Martian terrain

10:56 am

Yardangs on Mars

This week’s image release from the high resolution camera on Mars Reconnaissance Orbiter illustrate well the wild and mysterious geology of the Martian surface. I include cropped sections from two images here, just to give you a taste. Go to the link to do your own exploring.

The image to the right is a cropped and scaled down version of the original image, so the details are not easily seen. Make sure you look at the original. The strange yardang ridges, all aligned alike, rise up out of a relatively smooth plain.

Yardangs are formed when a surface that is composed of materials of differing strengths (i.e., of both harder and softer materials) is shaped by the abrasive action of sand and dust carried by the wind. In this case, and given the proximity of the Apollonaris Patera volcanic center, we think that these wind-carved deposits are comprised of volcanic ash and pyroclastics that erupted from Apollonaris when it was last active in the not-too-distant geologic past. Over time, the softer materials (likely volcanic ash) were eroded away, leaving behind the harder materials in the form of elongated ridges that are parallel to the direction of the prevailing wind. The end result is a stunning, out-of-this-world display of yardangs, sculpted with the artistic chisel of the Martian wind.

That’s the theory, anyway. The actual geological process that formed these ridges is probably a lot more complicated.

The image below the fold illustrates the on-going surface activity on Mars.

A look at Ted Cruz’s election strategy

9:36 am

The presidential election: While other candidates trash Rand Paul, Donald Trump, and their supporters, Cruz refuses to do so, taking the high road in the expectation that he will eventually win those supporters when Paul and Trump drop out of the campaign.

As Cruz is quoted in this different article,

“I would … note that an awful lot of Republicans, including other Republican candidates, have gone out of their way to smack Donald Trump with a stick. Now I think that’s just foolish,” he said. Asked why, Cruz paused and then replied, “Donald Trump had a rally in Phoenix, Ariz. [to which] between 10 and 20 thousand people came out. When you attack and vilify the people at that rally as crazies, it does nothing to help Republicans win in 2016. I’d like every single person at that rally to show up and vote in 2016, knock on doors with energy and passion, and turn this country around. If Washington politicians show contempt and condescension to those [voters,] that is a path to losing at the ballot box.”

Though I don’t post much about election campaigns, this does not mean I do not follow them closely. Most of what happens is childish drivel (such as last week’s debate and the big to-do between Trump and Megan Kelly), but if you look for real nuggets of information about the candidates you can find them. These two stories illustrate the cool-headed strength of Ted Cruz. His track record shows he is not afraid to fight, but it also appears he knows how to choose his fights well.

I have liked Scott Walker for the same reasons. In Wisconsin he was willing to fight, but kept a cool head and held back from fighting over petty issues. The problem for Walker now is that he has seemed too cool-headed during the campaign, unwilling to do anything that might offend anyone. This is not going to win elections. Nor is it going to change things even if he should win.

DARPA awards phase 2 space plane contracts

9:05 am

The competition heats up: The second phase contracts in the development of a reusable space plane have been awarded by DARPA.

DARPA has awarded $6.5 million each to three companies for developmental design work, including Boeing (in partnership with Blue Origin), Northrop Grumman (in partnership with Scaled Composites and Virgin Galactic), and Masten Space Science Systems (in partnership with XCOR Aerospace).

The requirements are that the plane fly 10 times in 10 days, reach Mach 10+, put a 3,000 to 5000 pound payload in orbit, and cost less than $5 million per flight. In this new phase, the companies are to deliver finalized designs by 2016, with prototype development to follow.

NASA considers using Bigelow module for deep space missions

8:56 am

The competition heats up: Rather than build something in-house for gobs of money and decades of work, NASA is considering using Bigelow Aerospace’s largest inflatable modules for its deep space missions.

What has happened is that NASA has signed a joint agreement with Bigelow to study the possibility of using Bigelow’s B330 module as a transport habitat on long flights. The agency really has no choice, as it doesn’t have the funding to develop the necessary large spacecraft for these missions, and Bigelow can provide them to it for much less.

This description of the background of Bigelow’s inflatable modules illustrates why NASA can’t build these itself:

The B330 evolved from the Genesis I and II modules that Bigelow Aerospace had launched into space. Those technology demonstrators were born out of the NASA project known as TransHab. The TransHab was an inflatable module designed for the ISS but was ultimately cancelled in 1999 due to budget constraints. The module would have provided a 4 level 27.5 feet (8.4 meter) diameter habitat for the astronauts.

After TransHab was cancelled, Bigelow worked with NASA on a technology transfer, giving Bigelow Aerospace exclusive rights to the technology. Using this technology, Bigelow designed, built and launched two technology demonstrators. They are still on orbit today. Genesis I was launched in 2006 with it’s sister ship launching in 2007. Both ships tested flight operations processes and on-board electronics and have performed above design specifications. [emphasis mine]

Unlike NASA, as a private company Bigelow was able to build this technology quickly and at a low cost. With the new agreement, the goal will be study the operation of a B330 in independent flight in low Earth orbit. Whether an actual B330 will be build and launched however is not yet clear.

The Space Show modernization crowd-funding campaign

12:52 pm

For more than a decade David Livingston has been producing and hosting The Space Show, the aerospace industry’s most important outlet for telling the public what is happening in space.

Now David is starting a crowd-funding campaign to finance a major update to The Space Show archives, in order to make them fully searchable and thus accessible to historians and researchers. As he notes,

Our archives as of this morning contain 2, 524 interview programs. These interviews tell the story of the space industry as many guests were there when it started, when we went to the Moon, and even before SpaceX was started. But as it stands, nobody can search our archives for information, program content, breaking news, etc. The closest one can come to a search is the GuestSearch tool on our current website, but searches are not interactive and about two-thirds of our programs have no key words so a search using the GuestSearch tool is not very useful Space Show archives are a treasure of information and history. By making them fully searchable and of archival quality, everyone benefits, even the casual Space Show listener.

As a space historian, I think David’s effort here is essential. The data hidden in the Space Show archives is invaluable, describing the beginning of the commercial space industry better than any other source. Making it searchable would make this history available to future generations that otherwise would never see it.

Check out the campaign as well as the Space Show support site and contribute. Not only can you help future space historians you will help keep the Space Show on the air.

Contract to build upgraded Vega rocket signed

9:58 am

The competition heats up: The European Space Agency today signed a contract to develop an upgraded version of its Vega rocket.

With respect to the VEGA configuration currently in operation, VEGA C aims to increase the load capacity of the orbital launcher up to 50%. Together with a further increase in operational flexibility, while maintaining its unrivalled orbital precision, it is expected to expand the capability to transport in the same flight a larger number of small satellites, in different orbital planes, or larger satellites. The new version of VEGA will be flight qualified in late 2018 for an entry into service as early as 2019. The group of countries which already participated in the development of VEGA, with Italy playing a major role with a 65% participation, welcomes now the entry of Germany.

I get the impression from this article that Vega is being used by ESA to spread the pork around, since to get Ariane 6 built they had to agree to not do so and give the work and control entirely to Airbus Safran. I thus wonder how competitive Vega will truly be.

Orbital ATK orders second Atlas 5 for launching cargo to ISS

9:43 am

In the heat of competition: Even as it has accepted delivery of two new Russian engines to power its Antares rocket, Orbital ATK has ordered a second Atlas 5 rocket to launch its Cygnus cargo capsule to ISS.

I suspect they want to give themselves some cushion time to test and install these new Russian engines prior to an actual launch. In order to fulfill their contract with NASA, however, they have to launch several times next year, thus requiring more replacements for Antares.

Where is Pluto’s nitrogen coming from?

9:28 am

As New Horizons’ engineers download data and plan future maneuvers to fly past one of two candidate Kuiper Belt objects, the science team today outlined the background mystery of Pluto’s nitrogen.

Pluto’s atmosphere is similar to Earth’s in that it is predominantly composed of nitrogen (N). But Pluto’s atmosphere is ~98% N, while Earth’s is only ~78% N. Pluto’s atmosphere is also considerably thinner than Earth’s with ~10,000 times lower pressure at the surface.

The nitrogen in Pluto’s atmosphere (in the form of N2 gas) is actually flowing away and escaping the planet at an estimated rate of hundreds of tons per hour. We also see what looks like flowing ice on Pluto’s surface in high resolution images made by New Horizons. The water ice (H2O) that we are familiar with on Earth would be completely rigid and stiff at Pluto’s surface temperatures, but ice made out of N2 would be able to flow like a glacier. So where does all of this nitrogen come from?

They have rejected comets as a source, and have predicted that geologic activity on Pluto itself could dredge the nitrogen up from the planet’s interior. (This prediction by the way was made before the New Horizons’ flyby, which has proved it likely.)

If their theory ends up the answer, then they will also prove that Pluto is losing mass, albeit slowly. Nitrogen from within is being processed out of the interior, into the atmosphere as gas, and then into space because Pluto’s gravity is too small to hold it.

July 4th flash flood captured on video

6:01 pm

An evening pause: Hat tip to caver Ray Keeler. As noted by Walt Willis, who had tipped Ray off and knows some of the people on this rafting trip,

They were rafting on the San Juan river and camped in a side canyon for the night. It started to rain so they all went under an overhang to stay dry (good decision). The person in blue (doing all the yelling) is my Cousin.

There are obvious lessons to be learned here. One never ever discounts “Luck”. They lost some of their gear but left with their lives. My Cousin was yelling at one of her friends not to go out and try and save anything.“ He thought better of the idea and stayed put. She proved that the sign above my desk is not always correct (“You Can’t Fix Stupid”).

Astronomers chart the universe’s slow death

9:40 am

Using data gathered from more than 200,000 galaxies, astronomers have been able to measure the slow decline in the universe’s energy output since the Big Bang.

The fact that the Universe is slowly fading has been known since the late 1990s, but this work shows that it is happening across all wavelengths from the ultraviolet to the infrared, representing the most comprehensive assessment of the energy output of the nearby Universe. “The Universe will decline from here on in, sliding gently into old age. The Universe has basically sat down on the sofa, pulled up a blanket and is about to nod off for an eternal doze,” concludes Simon Driver.

I wish to note the significant uncertainty of this result. While this result is important and does strongly suggest that the universe is dying, 200,000 galaxies is hardly a significant representation of the universe’s galaxy population.

Ten years after the Russians did it, NASA finally produces lettuce in space

9:29 am

Lots of news stories today about yesterday’s lettuce feast on ISS, where a Japanese and two NASA astronauts chowed down on lettuce grown in a NASA-built space greenhouse, ten years after the Russians did it with the American-built and still working LADA greenhouse.

Almost all the stories below, however, fail to note that earlier effort, and instead make the false claim that this NASA experiment is the first to grow lettuce in space.

Only the last article, written at an alternative space news website normally focused on the collection of space memorabilia, gets it right, noting that the Russians did it more than a decade ago and have since then been regularly growing lettuce, peas, and radishes on ISS — and eating them. (They also link to the 2003 Air & Space article I wrote on this very subject.)

Meanwhile, take a scan of all the important mainstream news outlets above, none of whom did the slightest bit of research or fact-checking so they could find out that NASA’s experiment now is not the first, and in fact is more than a decade behind an earlier co-operative effort between the Russians and Utah State University.

This should make you wonder if maybe their other news research is as sloppy.

Update on Boeing’s CST-100

8:55 am

This article provides an update on the status of the construction of Boeing’s CST-100 manned capsule.

It also describes NASA’s lobbying effort with Congress to get the full budget it had proposed for the construction of the commercial crew spacecraft.

I note instead the apparent bureaucratic focus of all the work Boeing seems to be doing.

Following the CBR [Certification Baseline Review], Boeing successfully completed the Ground Segment CDR (Critical Design Review) on 4 December 2014 before moving onto the Phase 2 Safety Review (Part B) in early January 2015. By mid-March, Boeing completed the Phase 2 Safety Review (Safety Technical Review Board Readiness) and moved on to the Delta Integrated CDR, which took place on 27 March 2015.

Since then, Boeing has spent the summer months conducting the Phase 2 Safety review (STRB 80%) as well as producing the CDR for the launch elements of the program and the Qualification Test Article Production Readiness Review.

Moreover, in late July, teams at the Kennedy Space Center began building the Structural Test Article (STA) for the CST-100 capsule inside former Orbiter Processing Facility bay 3 (OPF-3).

Lots of reviews, but notice in the last paragraph they have only begun building the first capsule. As much as these reviews might help them make sure they are doing things right, they seem to create a situation where the company is able to slow-walk construction to help NASA with its congressional lobbying effort, while simultaneously making it sound like they are accomplishing a lot.
