Worms on Mars!

9:09 am

Scientists growing plants on Earth using a simulated Martian soil have found that earthworms like it.

These slimy invertebrates play a key role in making Earth soil healthy by digesting dead organic matter and excreting a potent fertilizer that helps release nutrients like nitrogen and phosphorus. Their constant burrowing also helps lighten up the soil, allowing air and water to seep through better.

That’s an important improvement for the simulated Mars soil, which water struggled to soak through in previous tests. Altogether, the tests showed that the combination of worms and pig slurry helped the plants grow in Martin soil, and the worms not only thrived but reproduced. “Clearly the manure stimulated growth, especially in the Mars soil simulant, and we saw that the worms were active,” says Wamelink. “However, the best surprise came at the end of the experiment when we found two young worms in the Mars soil simulant.”

Obviously, we do not know yet how the worms would respond to the lower Martian gravity, but it sure would be a significant experiment to see them reproduce there.

SpaceX raises another $100 million in investment capital

9:03 am

Capitalism in space: In its current round of stock sales SpaceX had raised another $100 million in investment capital.

In August, the space exploration company sold $349.9 million worth of shares, a Securities and Exchange Commission (SEC) filing showed. That amount has now risen to $449.9 million, a new filing showed on Monday, adding an extra $100 million onto the current fundraising effort.

The latest injection of cash values SpaceX at $21.5 billion, according to Equidate, a platform that facilitates the trading of shares in private technology firms. SpaceX was not immediately available for comment on the valuation when contacted by CNBC.

If I was a big money investor I too would be interested in buying some SpaceX stock. Meanwhile, Aviation Week is reporting that the first Falcon Heavy launch has slipped to 2018. I am not surprised, but I have also not seen any other news reports on this, so I am withholding judgement.

Second Soyuz launch from Vostochny a failure

8:50 am

The second Soyuz rocket launch from Russia’s new spaceport in Vostochny ended in failure this morning due to a problem with the rocket’s upper stage

It is presently unclear what happened. One Russian news report suggests “human error,” though I do not understand exactly what they mean by that. Either way, all 19 satellites, including a new Russian weather satellite and 18 smallsats, were lost.

For Russia, this failure comes at a bad time. Roscosmos had been striving to recover from last year’s recall of all rocket engines due to corruption at one of their factories. A new launch failure, especially if it is due to another engine issue, will not encourage sales from the international market. Worse, the lose of the 18 smallsats on this launch will certainly make future smallsat companies more reluctant to fly on a Russian rocket.

Europe finally begins to realize that reusability cuts costs

11:19 pm

Capitalism in space: Faced with stiff and increasing competition from SpaceX, European governments are finally beginning to realize that their decades of poo-pooing the concept of rocket reusability might have been a big mistake.

In what was likely an unexpected question during a Nov. 19 interview with Europe 1 radio, French Economy and Finance Minister Bruno Le Maire was asked if SpaceX meant the death of Ariane.

“Death? I’m not sure I’d say that. But I am certain of the threat,” Le Maire said. “I am worried.” Le Maire cited figures that are far from proven — including a possible 80% reduction in the already low SpaceX Falcon 9 launch price once the benefits of reusability are realized. “We need to relfect on a reusable launcher in Europe, and we need to invest massively in innovation,” Le Maire said.

Then there was a report out of Germany that has concluded that SpaceX commitment to reusability is about to pay off.

The article also cites those in Europe and with the U.S. company ULA that remain convinced that they can compete with expendable rockets. In reading their analysis, however, I was struck by how much it appeared they were putting their heads in the sand to avoid facing the realities, one of which has been the obvious fact that SpaceX has been competitively running rings around them all. This is a company that did not even exist a decade ago. This year it very well could launch more satellites than Europe and ULA combined.

New report says WFIRST is “not executable”

11:05 pm

Another Webb! New NASA report has declared the agency’s next big telescope following the James Webb Space Telescope, dubbed the Wide Field Infrared Survey Telescope (WFIRST) is “not executable” and is significantly over budget.

“The risks to the primary mission of WFIRST are significant and therefore the mission is not executable without adjustments and/or additional resources,” the report states. It estimated the cost of the project at $3.9 billion to $4.2 billion, significantly above the project’s $3.6 billion budget.

Produced by an independent and external team to review the technical aspects of the program, its management, and costs, the report is critical of a series of key decisions made by NASA. The addition of a coronagraph and other design choices have made for a telescope that is “more complex than probably anticipated” and have substantially increased risks and costs, according to the report.

It also offered a scathing review of the relationship between NASA headquarters and the telescope’s program managers at Goddard Space Flight Center. “The NASA HQ-to-Program governance structure is dysfunctional and should be corrected for clarity in roles, accountability, and authority,” the report states.

Did you ever get a feeling of deja-vu? This is the same story that we saw with Hubble, and with Webb. It’s called a buy-in. The agency purposely sets the budget too low to begin with, gets it started, which then forces Congress to pay the big bucks when the budget inevitably goes out of control.

From my perspective I think this is the time to shut the project down. Since Hubble astronomers have apparently begun to take NASA’s cash cow for granted, and need to relearn the lesson that they don’t have a guarantee on the treasury. Once they get over the shock of losing WFIRST, they might then start proposing good space telescopes that are affordable and can be built relatively quickly, instead of these boondoggles that take forever and ten times the initial budget to build.

Another Evergreen employee resigns to protest college policies

9:25 am

Fascist and corrupt: Another Evergreen employee has resigned to protest policies at the leftist college, including some of which appear to violate state law.

Michael Radelich, who left the Washington state public college earlier this month, told The College Fix the Writing Center had been using financial aid money intended for students to hire non-student workers….According to documents given to The Fix by Radelich, the Writing Center spent 73 percent of its budget on items other than student salaries during the 2016-2017 academic year. Of that amount, 55 percent was spent on non-student temporary assistants and 18 percent on non-student elements of Inkwell, the annual magazine it produced.

…According to the exit survey that Radelich filled out and submitted when he left, “the college’s financial policy makers” told Yannone “every year” that she needed to spend at least 90 percent of her budget on student salaries. “She was always told you can’t be hiring temporary workers that are paid with student funds. There was no oversight from stopping her from doing that,” Radelich said in the interview near WWU.

In addition, the article describes how Radelich wanted out because of the college’s unbearable leftist politically correct culture.

Why anyone is sending their children to this college baffles me. The last thing anyone would accomplish there is to learn how to think.

Russia astronauts have found bacteria living on the outside of ISS

8:42 am

Russia astronauts have found bacteria that was not intentionally brought into space living on the outside of ISS.

They are being studied on Earth but most likely they don’t pose any sort of danger, Russian cosmonaut Anton Shkaplerov told TASS on Monday. According to him, during spacewalks from the International Space Station under the Russian program, the cosmonauts took samples with cotton swabs from the station’s external surface. In particular, they took probes from places where the accumulation of fuel wastes were discharged during the engines’ operation or at places where the station’s surface is more obscure. After that, the samples were sent back to Earth.

“And now it turns out that somehow these swabs reveal bacteria that were absent during the launch of the ISS module. That is, they have come from outer space and settled along the external surface.”

I suspect it is a bit of hyperbole to say the bacteria came from outer space. It more likely came from either the station itself, or later spacecraft docking with the station. At the same time, the article is vague about what has been discovered. For example, it says nothing about the bacteria itself.

California cities charge citizens massive prosecutions fees for minor violations

8:48 pm

Fascist California: Two California cities fine citizens for minor offenses, then force them to pay the exorbitant bills of the lawyers who prosecuted them.

The cities of Indio and Coachella partnered up with a private law firm, Silver & Wright, to prosecute citizens in criminal court for violations of city ordinances that call for nothing more than small fines—things like having a mess in your yard or selling food without a business license.

Those cited for these violations fix the problems and pay the fines, a typical code enforcement story. The kicker comes a few weeks or months later when citizens get a bill in the mail for thousands of dollars from the law firm that prosecuted them. They are forcing citizens to pay for the private lawyers used to take them to court in the first place. So a fine for a couple of hundred dollars suddenly becomes a bill for $3,000 or $20,000 or even more.

In Coachella, a man was fined $900 for expanding his living room without getting a permit. He paid his fine. Then more than a year later he got a bill in the mail from Silver & Wright for $26,000. They told him that he had to pay the cost of prosecuting him, and if he didn’t, they could put a lien on his house and the city could sell it against his will. When he appealed the bill they charged him even more for the cost of defending against the appeal. The bill went from $26,000 to $31,000.

There’s more, including the fact that when challenged it appeared that the officials of one of theses cities were actually proud of what they are doing.

A mission to interstellar object Oumuamua?

11:31 am

A private company and a volunteer group dedicated to promoting interstellar travel have written a paper [pdf] exploring the possibility of launching a mission to fly past the interstellar object Oumuamua, now speeding out of our solar system.

As they note in the paper’s abstract,

Can such objects be intercepted? The challenge of reaching the object within a reasonable timeframe is formidable due to its high heliocentric hyperbolic excess velocity of about 26 km/s; much faster than any vehicle yet launched. This paper presents a high-level analysis of potential near-term options for such a mission. Launching a spacecraft in a reasonable timeframe of 5-10 years requires a hyperbolic solar system excess velocity between 33 to 76 km/s for mission durations between 30 to 5 years. Different mission durations and their velocity requirements are explored with respect to the launch date, assuming direct impulsive transfer to the intercept trajectory. Several technology options are outlined, ranging from a close solar Oberth Maneuver using chemical propulsion, and the more advanced options of solar and laser sails. To maximize science return decelerating the spacecraft at ’Oumuamua is highly desirable, due to the minimal science return from a hyper-velocity encounter. It is concluded that although reaching the object is challenging, there seem to be viable options based on current and near-term technology.

The paper even considers the use of SLS or SpaceX’s Big Falcon Rocket.
