NASA wants to use its SLS mobile launch once, then replace it

9:06 am

Government in action! After spending almost a half billion to reconfigure the Apollo mobile launcher first for Ares and then for SLS, NASA now says it needs to build a completely new mobile launcher to replace it.

Apparently, all the work did not make the mobile launcher usable for the larger SLS that will launch astronauts.

According to Hambleton, NASA has made no decision on a second mobile launcher. She declined to address the question of costs. A 2012 report from NASA’s inspector general estimated the costs of building a new mobile launcher then at $122 million, but a new structure expressly for the larger Block 1B rocket to be used for the second flight of the SLS rocket would almost certainly cost more.

Additionally, If NASA builds a new mobile launcher, the modified one now being configured for the first SLS flight would likely be used just once—a waste of infrastructure that cost perhaps half a billion dollars and more than a decade of development.

The absurdity of this is appalling. They spent a decade and half a billion reconfiguring the mobile launcher, under the guise that reusing the old one saved NASA money. Now they want to build a new one?

First discoveries from China’s FAST radio telescope

8:58 am

Astronomers using China’s new FAST radio telescope have announced its first discoveries, the identification of two pulsars,

The new pulsars PSR J1859-01 and PSR J1931-02, also referred to as FAST pulsar #1 and #2 (FP1 and FP2), were detected on August 22 and 25, and were confirmed by the Parkes telescope in Australia on September 10. “FP1 is a pulsar with a spin period of 1.83 second and an estimated distance of 16 thousand light-years, and FP2, is a pulsar with a spin period of 0.59 second and an estimated distance of 4,100 light years,” said Li Di, Deputy Chief Engineer of FAST Project at the National Astronomical Observatories (NAOC), on Tuesday.

FAST’s gigantic size will allow it to pinpoint many similar astronomical objects previously beyond the resolution of radio telescopes.

Note that there is still no word on whether China has found a scientist to head FAST operations.

NanoRacks and Moon Express team up for lunar missions

8:53 am

Capitalism in space: The private space company Moon Express has signed an agreement with NanoRacks to help manage its planned lunar commercial missions.

Under the agreement, NanoRacks, a company best known for transporting satellites and other payloads to the International Space Station, will handle sales, marketing and technical support for payloads that will fly on Moon Express’ series of lunar lander missions, starting in early 2018. “The primary goal of our alliance with NanoRacks is to ensure a great customer experience,” said Bob Richards, founder and chief executive of Moon Express, in a statement. “Our companies share a culture of customer focus, and together we will be able to provide end to end support from payload concept to mission operations.”

NanoRacks does similar work for researchers and cubesat manufacturers who want access to ISS. They act as the go-between, bundling the different projects and arranging them with NASA.

The mysterious dark splotches of Mars

The dark splotches of Mars

Cool image time! The image on the right, cropped and reduced in resolution to post here, shows one particular dark splotch in a region with several similar dark areas.

Geologists aren’t quite sure what to make of the dark splotch in the middle of this image, one of several similar dark splotches that extend east and west for over 100 kilometers. From measurements made in infrared, this and other dark splotches have what we call “high thermal inertia,” meaning that it heats up and cools down slowly. Scientists use thermal inertia to assess how rocky, sandy, or dusty a place is. A higher thermal inertia than the surrounding area means it’s less dusty.

The image below the fold shows at full resolution the area indicated by the white box. It provides me no clue as to the cause for the darker color. I think we can speculate all we want, but the truth is that we simply don’t have enough information. We need a closer look, including boots on the ground, to figure this out.

Why electric cars for interstate travel cannot work

10:49 am

Link here. He does the math, and finds the infrastructure for providing the charging stations necessary to make electric interstate travel possible to be prohibitive.

The bottom line really has more to do with the stupidity of governments banning the use of gasoline cars and dictating the use of electric cars, regardless of what the engineering can do and the economical factors involved. It is much better to leave these decisions up to the free market, with emphasis on the word free. If electric cars are economical, they will eventually replace gasoline. If not, they won’t, and if governments mandate their use all that will happen is that everyone will be poorer, and the environment will likely be worse off.

Sunspot update for September 2017

9:38 am

On Sunday NOAA posted its monthly update of the solar cycle, covering sunspot activity for September. That graph is posted below, with annotations.

September 2017 Solar Cycle graph

The graph above has been modified to show the predictions of the solar science community. The green curves show the community’s two original predictions from April 2007, with half the scientists predicting a very strong maximum and half predicting a weak one. The red curve is their revised May 2009 prediction.

Last month saw the strongest amount of sunspot activity in a year, thus helping to bring the pace in the decline of sunspot activity back towards the low prediction from April 2007. This also suggests that the ramp down to solar minimum will continue through 2019, with minimum not occurring before then, at the earliest. At the same time, the increase in sunspot activity seen in September seems to have eased in October, with the return of a blank Sun this past week.

A modern academic looks at the Outer Space Treaty

8:40 am

Link here. I could also label this another sign of the coming dark age. Consider her proposals:

Space laws need to be updated for our time. Extending the Outer Space Treaty or writing a new one is unlikely to work, as US hesitancy to sign the [Treaty on Prevention of the Placement of Weapons in Outer Space and of the Threat or Use of Force Against Outer Space Objects (PPWT)] shows. ‘Soft law’, driven by need, seems the best option for revising the rules for space operators.

Soft law comprises rules or guidelines that have legal significance but are not binding. It sets standards of conduct for agreeing parties, much like those that protect the environment and endangered species. ‘Rules of the road’ and best practices for space should be developed. These could take a similar form to the navigation guidelines set out in the 1972 Convention on International Regulations for Preventing Collisions at Sea, which govern when one vessel should give way to another, as well as other interactions.

Soft law works when it is in the interest of all parties to abide by it. If countries and companies want to maintain the space environment as a usable domain, then it is in their interests to accommodate a variety of operations. Space is more complex to manage than air, land or sea because of the distance, physics and technology involved. Just as in the cyber domain, technology has preceded regulation, making it difficult to impose after the fact.

The first focus of an analogous set of space guidelines should be environmental protection and debris avoidance, areas that most spacefaring nations agree on. [emphasis mine]

Rather than fix a bad law, the Outer Space Treaty, that is binding on everyone, she proposes the we make the laws “soft,” thus unreliable because everyone can ignore them whenever they want. The result? Utter contempt for the law.

Then she indicates her main interest, which isn’t exploration or the settlement of the solar system, which is the actual interest of the people who are building rockets and spaceships, but “environmental protection.” Above all, we must establish strict regulations that will prevent those pristine lifeless worlds from being damaged by us evil humans!

If anything is a prescription for stunting the growth of space exploration, this is it. Unfortunately, it appears that this prescription is also the dominate intellectual approach of today’s academic community.

Death threats force journal to remove pro-colonialism paper

8:49 pm

The fascists win: Death threats have finally forced the academic journal Third World Quarterly to take down a paper that had expressed some pro-colonialism ideas.

In a “withdrawal notice” posted on the now-blank “Viewpoint” article page, publisher Taylor & Francis said the death threats were “serious and credible” and “linked to the publication of this essay.” It reiterated against contrary claims that the article had “undergone double-blind peer review.”

Gilley [the author] himself had asked for the article’s withdrawal following a coordinated international campaign to ruin his reputation and blacklist him from other journals, and to shame Third World Quarterly into removing it. Fifteen members of its editorial board resigned in protest of its publication.

What had Gilley said that was so terrible?

Research …often finds that at least some if not many or most episodes of Western colonialism were a net benefit…Such works have found evidence for significant social, economic and political gains under colonialism: expanded education, improved public health, the abolition of slavery, widened employment opportunities, improved administration, the creation of basic infrastructure, female rights, enfranchisement of untouchable or historically excluded communities, fair taxation, access to capital, the generation of historical and cultural knowledge, and national identify formation, to mention just a few dimensions.

He couched this statement with numerous caveats and politically correct expressions of doubt, in the hope the mob would not come after him for stating something that is simply not permitted in today’s modern fascist academic community. I should also note that as a historian who has researched this subject myself, his position is easily documented by numerous papers across the entire field. The colonialism movement of Europe had numerous bad aspects, but numerous benefits as well for the countries colonized.

None of this mattered. Gilley had blasphemed against the leftist anti-western ideology, and had to be destroyed, along with anyone else who even hinted at mild support.
