Breakthrough increases plant yields by one third

9:29 am

Plant scientists have found a way to encourage plants to better use atmospheric nitrogen, thus increasing yields by more than one third.

For years, scientists have tried to increase the rate of nitrogen fixation in legumes by altering rhizobia bacterioid function or interactions that take place between the bacterioid and the root nodule cells.

Tegeder took a different approach: She increased the number of proteins that help move nitrogen from the rhizobia bacteria to the plant’s leaves, seed-producing organs and other areas where it is needed. The additional transport proteins sped up the overall export of nitrogen from the root nodules. This initiated a feedback loop that caused the rhizobia to start fixing more atmospheric nitrogen, which the plant then used to produce more seeds. “They are bigger, grow faster and generally look better than natural soybean plants,” Tegeder said. “Some evidence we have suggests they might also be highly efficient under stressful conditions like drought.”

The technique not only produces healthier plants and more seeds, it reduces the need for fertilizer, the overuse of which can be an environmental issue.

The Moon gets pounded more than expected

8:55 am

The uncertainty of science: A close review of Lunar Reconnaissance Orbiter (LRO) images now suggests that asteroid impacts occur 33% more than previously estimated.

The research also suggests that the lunar surface gets rechurned faster than previously thought, which could force planetary scientists to adjust their solar system aging system that is based on crater counts.

The article makes the entirely false claim that this increased rate of impacts poses a threat to lunar colonies, probably in an effort by these scientists to lobby for funds for a combined lunar orbiter-lander mission. The first lunar colonies will likely be placed below ground, partly to protect them from the harsh lunar environment as well as from radiation, and partly because that will be the easiest way to build those colonies. The impacts being measured here are all relatively small, and would not threaten these underground colonies.

Vector Space Systems to open Tucson facility

8:38 am

The competition heats up: Vector Space Systems has decided to build a rocket manufacturing facility in Tucson.

The Tucson-based company is expected to create 200 jobs locally within three years of beginning operations, at an average annual salary of $70,000. It could employ as many as 500 people within five years as production ramps up, said its co-founder and CEO, Jim Cantrell. Vector plans to invest roughly $19 million during the first three years, and possibly as much as $50 million over the next 15 years, according to Pima County officials. The total direct economic impact of the facility could be $290 million over five years, says an analysis by Phoenix-based Applied Economics completed for Sun Corridor Inc., the local economic-development agency. The company plans to build 36,000 square feet of office space and another 40,000 square feet for manufacturing south of Tucson International Airport.

The company already has several million in smallsat launch contracts, plus options for $160 million more once they begin producing rockets.

The first nation in space?

8:29 am

A science research center has announced it is forming an independent nation in space which anyone can join.

If you are 18 or over and have an email address, you can apply to become a ‘citizen’ of Asgardia today. At the time of this writing, more than 4,900 people have signed up, including at least one Popular Science editor. “When the number of those applications goes above 100,000 we can officially apply to the UN for the status of state,” said Ashurbeyli, adding that Asgardians would not have to give up citizenship in their countries of origin.

The group hopes to launch its first satellite in 2017 or 2018. How it will avoid being under the jurisdiction of any other country remains to me a mystery.

Eventually, when there are thriving reasonably self-sufficient colonies in space, circumstances will demand that they declare their independence from what is becoming an increasingly oppressive Earth culture. Until then, declarations like Asgardia are nothing more than publicity stunts that are not going to go anywhere.

TMT considers alternative sites to Hawaii

9:36 am

Faced with a continuing legal battle to build the Thirty Meter Telescope (TMT), the consortium running is now seriously considering alternative sites.

Potential Northern Hemisphere sites include San Pedro Mártir in Baja California in Mexico and Roque de los Muchachos on La Palma, a Spanish island off the Atlantic coast of Morocco. “Our friends in La Palma are pushing hard” to get the TMT, says Matt Mountain, president of the Association of Universities for Research in Astronomy in Washington, D.C. But neither alternative matches the seeing conditions on Mauna Kea, and they would bring extra cost and complication. The project has already ruled out sites in the Himalayas, put forward by India and China—both TMT partners along with the United States, Japan, and Canada—because they are too far from ports and have short construction seasons.

The TMT governors are expected to choose their top alternative site later this month. Regardless of what happens in Hawaii, the governors have vowed to start construction—on Mauna Kea or elsewhere—no later than April 2018.

It is clear that Mauna Kea in Hawaii is the best location. Unfortunately, they are faced with the reality that there might be years of delays before they ever get permission to build, if they get permission at all.

Russia gets two contracts for Proton

9:30 am

The competition heats up: Russia has signed two new contracts using its newly announced Proton-Medium rocket configuration.

Both contracts are for the same launch. The primary payload will be a Intelsat communications satellite. The secondary payload will be Orbital ATK’s first Mission Extension Vehicle (MEV-1), which is actually more significant and somewhat ground-breaking.

The MEV-1 provides life-extending services by taking over the propulsion and attitude control functions. Satellites have an average of 15 years of life on orbit, before they need to be replaced. The vehicle itself has a 15-year design life with the ability to perform numerous dockings and undockings during its life span. “Rather than launching new satellites, operators can extend the life of healthy in-orbit satellites, providing enhanced flexibility through Orbital ATK’s scalable and cost-efficient capabilities,” noted Our simple approach minimizes risk, enhances mission assurance, and enables our customers to realize the maximum value of their in-orbit satellite assets.”

The launch of MEV-1 will involve in-orbit testing and a demonstration to be performed with an Intelsat satellite. MEV-1 will then relocate to the Intelsat satellite scheduled for the mission extension service, which is planned for a five-year period. Intelsat will also have the option to service multiple satellites using the same MEV.

If MEV-1 proves successful, Orbital ATK will have built, launched, and made money from the first robot repair satellite. While at first glance this success suggests that satellite companies will need to launch fewer satellites, thus reducing the market demand for rockets, what it will really do is make the orbiting satellite more useful and profitable, thus encouraging new players to enter the market. The demand for satellites will increase, thus increasing the demand for rockets.

Ain’t freedom and private enterprise grand?

Boeing pushes back first Starliner flights

9:17 am

Boeing has delayed the first test flight of its Starliner manned capsule from the end of 2017 until June 2018.

Boeing says that production delays and problems with qualification tests are partly to blame for the timeline slip. The company also found a production flaw in September that forced them to get rid of a main element on one of their spacecrafts — a dome that made up the pressure shell of the crew module. All of these complications combined prompted Boeing to push back the development timeline of Starliner by about six months.

A*Teens – Halfway Around The World

6:01 pm

An evening pause: Watching this only confirms for me a well known fact: Young people sure have more energy than they know what to do with. In this case, it is used well.

Hat tip Jim Mallamace, who adds that this “Swedish group originally formed as an ABBA tribute band (originally, they called themselves “ABBA Teens”). As they became older, they branched out into their own music selections that had nothing to do with ABBA.”

NASA to offer port on ISS for private modules

3:58 pm

The competition heats up: NASA to offer port on ISS for private modules.

Several companies have previously expressed an interest in adding a module to the ISS for commercial or NASA use. In April, Bigelow Aerospace said it had made an unsolicited proposal to NASA to add one of its B330 modules under development to the ISS. In August, the company received an award from NASA’s Next Space Technologies for Exploration Partnerships (NextSTEP) to study that concept in more detail.

Axiom Space, a company led by former NASA station program manager Mike Suffredini, announced in June plans to develop a commercial module that could be added to the station as a precursor to a standalone commercial space station. Suffredini said in July that his company planned to respond to the NASA RFI.

Another venture that received a NASA NextSTEP award in August was a consortium called Ixion, which includes NanoRacks, Space Systems Loral and United Launch Alliance. Ixion will study converting a Centaur upper stage into a commercial ISS module.

This confirms my belief that ISS will not be retired in 2024, but will slowly transition to private hands and will be steadily replaced by new private modules as old ones wear out.

A large Kuiper Belt object discovered

3:55 pm

Astronomers have detected a new but very distant Kuiper Belt object.

For now, his team knows little more about their distant discovery other than its orbit and apparent brightness. Given its distance, however, the object should be sizable — anywhere from 400 km across (if its surface is bright and 50% reflective) to 1,200 km (if very dark and 5% reflective). If its true size edges toward the larger end of this range, then 2014 UZ224 would likely qualify for dwarf-planet status.

Fortunately, we should have a much better estimate of the object’s size very soon. Gerdes has used the ALMA radio-telescope array to measure the heat radiating from 2014 UZ224, which can be combined with the optical measurements to yield its size and albedo.

The object has a very eccentric 1,140 year orbit, coming as close to the sun as Pluto at its closest and almost five times farther away at its furthest.

Note: I have changed the article title because this new object is almost certainly not bigger the Pluto, as one of my readers pointed out.

Obama makes another empty space commitment

1:06 pm

In an op-ed today, President Barack Obama made another one of those Presidential Kennedy-like space commitments, this time proposing that the U.S. send humans to Mars.

We have set a clear goal vital to the next chapter of America’s story in space: sending humans to Mars by the 2030s and returning them safely to Earth, with the ultimate ambition to one day remain there for an extended time. Getting to Mars will require continued cooperation between government and private innovators, and we’re already well on our way. Within the next two years, private companies will for the first time send astronauts to the International Space Station.

Obama in his op-ed spends a lot of time claiming credit for the recent resurgence in the American space industry. Though his administration does deserve some of the credit, in that they continued and expanded the commercial space initiative first started in the Bush administration, the bulk of the credit here really must be given to the private companies that did the actual work. SpaceX and Orbital ATK took enormous financial risks to make their rockets and capsules fly. They made it happen, proving at last to a generation that had lost faith in private enterprise and freedom that relying on private enterprise and freedom really is the best way to do things.

Meanwhile, I would not take Obama’s proposal very seriously. We will have a new president in just a matter of a few months, and that president will make his or her own decisions. Moreover, it really won’t matter that much what that next president proposes anyway. The real story will be with private individuals and private companies, forging their own dreams as they search for ways to get into space in a profitable manner.

More madness from our intellectual betters

9:29 am

Below is another collection of links I have been gathering since last week, illustrating the intellectual bankruptcy that presently dominates American society and the so-called elite culture that is supposed to lead us.

I wish I could say that these stories are the exceptions that prove freedom and the demand from western civilization that we always seek the truth is still thriving in America, but if I did I’d be lying. These stories reflect the close-minded and oppressive attitude that is permeating our intellectual climate and is acting to squelch freedom and the ability of people to express alternative points of view.

The first three stories illustrate the hate of western civilization that dominates modern intellectual culture. The last three stories illustrate its close-mindedness. For example, consider the James Madison University speech guide:

Student leaders of this year’s freshman orientation at James Madison University were given a list of 35 things they should avoid saying, including phrases such as “you have such a pretty face,” “love the sinner, hate the sin,” “we’re all part of the human race,” “I treat all people the same,” “it was only a joke,” “I never owned slaves,” and “people just need to pick themselves up by their bootstraps,” among other expressions.

Meanwhile, a police chief (who happens to be black) is banned from speaking about the use of forensics in police work because he has had the nerve to publicly criticize the racist Black Lives Movement. We can’t have that!

The worst aspect of these stories is the lack of resistance to these totalitarian measures. If I was attending James Madison University, my response to that speech guide would be to start wearing t-shirts with those banned phrases blazoned across the front, while chalking those phrases everywhere on sidewalks. I do not get the sense that today’s students have the same courage. In fact, the story on trigger warnings suggests that today’s students are wholly in favor of this oppression, and get upset if anyone dares express a dissenting view to them.

Cosmic rays a threat to Mars travel

8:45 am

The uncertainty of science: New research using rats has found that cosmic rays might damage human brains during a long mission to and from Mars.

Radiation oncologist Charles Limoli and his colleagues at the University of California Irvine bombarded mice and rats with low-doses of ionized oxygen or titanium. These charged particles have similar energies to those of cosmic rays that can pass right through the shielding on spacecraft. The dosage levels that the researchers used were similar to what astronauts would be exposed to during a three-year round-trip mission to Mars, Limoli says.

The researchers looked at the prefrontal cortex, the brain region linked to decision-making, executive function, and long-term memory. They saw significant damage and inflammation in the brains of exposed animals as long as six months after the exposure. The radiation damaged the tiny branches on neurons that help transmit electric signals to the nerve cell body. This led to a loss in learning and memory. The exposed animals performed poorly on behavioral tests that measure intelligence, and they showed higher, constant anxiety levels.

Though the uncertainties here are enormous, the research here has essentially discovered the obvious. The radiation experienced during a long interplanetary voyage is unhealthy, and any interplanetary vessel for carrying humans on such a voyage must be designed with sufficient shielding to protect its passengers. That this research has proven that cosmic rays are a threat also means that providing a ship with a safe room where passengers can take refuge during solar storms is not sufficient. Cosmic rays are random and come at all times in an unpredictable manner. The research suggests that the shielding will have to protect the ship’s entire living quarters.

The payload weight requirements for any rocket that will launch the first interplanetary ships just went up significantly. This means that space stations we have been building (Mir, ISS, and Tiangong) are not even close to sufficient for interplanetary travel, and need significant redesign to make them work. This also means that human interplanetary travel will require cost-efficient heavy lift rockets such as the Falcon Heavy.
