Capitalism in space: For the first time SpaceX yesterday successfully caught both fairings halves in the nets of their ships as they floated down to the ocean on their parasails.
Previously they have mostly plucked the fairings from the sea, though they have caught a few in the netting of the ships. To catch both simplifies the preparation for the next flight enormously, as they never touched the water.

Using a variety of telescopes, especially the Jansky Very Large Array radio telescope, astronomers have successfully mapped the magnetic field lines of a spiral galaxy seen edge on and 67 million light years away.
The image to the right, cropped and reduced to post here, shows what they have found.
The magnetic field lines extend as much as 22,500 light-years beyond the galaxy’s disk. Scientists know that magnetic fields play an important role in many processes, such as star formation, within galaxies. However, it is not fully understood how such huge magnetic fields are generated and maintained. A leading explanation, called the dynamo theory, suggests that magnetic fields are generated by the motion of plasma within the galaxy’s disk. Ideas about the cause of the kinds of large vertical extensions seen in this image are more speculative, and astronomers hope that further observations and more analysis will answer some of the outstanding questions.
Our understanding of these kinds of gigantic magnetic fields is poor, to put it mildly. This data really only begins the research.

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News
The tenth anniversary retrospective of Behind the Black continues: This essay was posted originally on July 20, 2010, then reposted on July 20, 2011, to celebrate the anniversary of the Apollo 11 landing on the Moon. It seems fitting to post it again, on this, the 51st anniversary of that landing.

A flag in the dust
Today, July 20th, is the anniversary of the Apollo 11 landing on the Moon, the first time ever that a human being arrived on another planet. Americans love to celebrate this event, as it symbolizes one of the finest moments in our history, when we set out to achieve something truly great and noble and succeeded far better than we could have imagined. Not only did we get to the Moon as promised, over the next three and a half years we sent another five missions, each with increasingly sophisticated equipment, each sent to explore some increasingly alien terrain. Forty-plus years later, no one has come close to matching this achievement, a fact that emphasizes how difficult it was for the United States to accomplish it.
There is one small but very important detail about the Apollo 11 mission, however, that most Americans are unaware of. » Read more
An evening pause: For this anniversary of Neil Armstrong’s first step on the Moon, a short musical piece, with images, that nicely encapsulates that 1960s space effort. If you are passionate about the human effort to become a space-faring civilization and you don’t know who and what mission each clip portrays, you need to find out.
Now available in hardback and paperback as well as ebook!
From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.
All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount.

They’re coming for you next: The Democrat prosecutor in St. Louis, circuit attorney Kim Gardner, who would eagerly ban you from owning guns and would also gladly defund the police, has issued criminal charges against the St. Louis couple for using their guns to protect their home from trespassing and threatening Antifa/BLM protesters.
The charge relates to them “flourishing” the guns while standing on their own property in order to ward off trespassers who were verbally and physically threatening them.
This is the Democratic Party today. Not only should you be denied the right to own guns, if you do own them you will not be allowed to defend your life with them. Moreover, there must not be any police available to enforce the law. These Democrats will also give carte blanche to any protesters they agree with, allowing them to trespass on your property and do what they will with you, in the name of free speech.
Capitalism in space: SpaceX today successfully launched a South Korean military satellite, with its Falcon 9 rocket using the same first stage that launched two American astronauts to ISS less than two months ago.
This was the company’s fastest turnaround yet of a used first stage, 51 days, which also beats the fastest turnaround ever by the shuttle program, 54 days. And as you can see by the screen capture image to the right, they successfully landed it so that it can be used for a third time.
Watching the camera on that first stage after separation (on SpaceX’s live stream) to landing was most fascinating. After separation its tail end points down to the west and its launch site in Florida. As it curves upward and then down towards its landing in the Atlantic, its small thrusters and grid fins very slowly and gracefully swing that tail to instead point east and down to the drone ship. I had not noticed previously the gentleness of that re-positioning. The daylight clear weather today, plus excellent camera access, made it very obvious.

The Texas Republican Party yesterday ousted its chairman to give former congressman and hard-nosed conservative Allen West the job.
Conservative firebrand and former Florida congressman Allen West will lead the Texas Republican Party into the 2020 election, after ousting the current chairman early Monday during a convention marred by technical difficulties. He vowed to use his post to push back against Democrats’ “progressive socialism.”
“I am sick and tired of Republicans being on their heels, being on the defense, always being reactionary with a party that as we see right now– they don’t stand up for the rule of law, they stand for rule of the mob,” he said during a victory lap on conservative media.
If anything, this decision indicates the continuing shift in the Republican Party from the milquetoast go-along-to-get-along types to those willing to fight the Democrats on all fronts. One of the reasons West lost his seat in Congress is because past Republican leadership looked at him with distaste, refusing to give him the kind of support he needed. That is now changing.
Today there were many many news stories touting the successful launch of the United Arab Emirates’ (UAE) first interplanetary probe, Hope, (al-Amal in Arabic), successfully launched yesterday from Japan. This story at collectSpace is typical, describing the mission in detail and noting its overall goals not only to study the Martian atmosphere but to inspire the young people in the UAE to pursue futures in the fields of science and engineering.
What most of these reports gloss over is how little of Hope was really built by the UAE. The UAE paid the bills, but during design and construction almost everything was done by American universities as part of their education programs, though arranged so that it was UAE’s students and engineers who were getting the education.

The tenth anniversary retrospective of Behind the Black continues: Tonight’s repost adds more weight to yesterday’s about the uncertainty of any model predicting global warming. Rather than look at the giant gaps in our knowledge, this essay, posted on January 28, 2019, looked at the data tampering that government scientists are doing to their global temperature databases in order to make the past appear cooler and the present appear warmer.
——————————-
The absolute uncertainty of climate science
Even as the United States is being plunged right now into an epic cold spell (something that has been happening repeatedly for almost all the winters of the past decade), and politicians continue to rant about the coming doom due to global warming, none of the data allows anyone the right to make any claims about the future global climate, in any direction.
Why do I feel so certain I can make this claim of uncertainty? Because the data simply isn’t there. And where we do have it, it has been tampered with so badly it is no longer very trustworthy. This very well documented post by Tony Heller proves this reality, quite thoroughly.
First, until the late 20th century, we simply do not have good reliable climate data for the southern hemisphere. Any statement by anyone claiming to know with certainty what the global temperature was prior to 1978 (when the first Nimbus climate satellite was launched) should be treated with some skepticism. Take a look at all the graphs Heller posts, all from reputable science sources, all confirming my own essay on this subject from 2015. The only regions where temperatures were thoroughly measured prior to satellite data was in the United States, Europe, and Japan. There are scattered data points elsewhere, but not many, with none in the southern oceans. And while we do have a great deal of proxy data that provides some guidance as to the global temperature prior to the space age, strongly suggesting there was a global warm period around the year 1000 AD, and a global cold period around 1600 AD, this data also has a lot of uncertainty, so it is entirely reasonable to express some skepticism about it.
Second, the data in those well-covered regions have been tampered with extensively, and always in a manner that reinforces the theory of global warming. Actual temperature readings have been adjusted everywhere, always to cool the past and warm the present. As Heller notes,

A close look at the infection rate based on the increased number of tests in the past two months suggests that by election day the entire country will be close to herd immunity, and that quite possibly 40% of the population is already immune.
As of July 17, 44.2 million people have been tested, with 3.63 million positives (8.2%). Those folks who tested negative either never contracted COVID-19 or had it (with or without symptoms) and recovered.
…One eighth of the country [44.2 million] already tested is a very large sample, statistically. Applying the 8% baseline infection rate to the entire population, this means that every week after the beginning of April, another 2.67% of the people in the U.S. had recovered from COVID-19, were immune and non-contagious, and were not a threat to anybody. These numbers are additive. By July 17 (15 weeks), 40% of the country is now immune to the coronavirus, whether or not these people know it, and they cannot infect anybody else (for as long as the period of immunity lasts, likely well into the fall).
We can use the trajectory of the “hot spots” in March and April (which peaked about mid-April) to estimate the future trajectory of the percent of nationwide positive COVD-19 test results — which are now less than 2% in the former hot-spot areas — as the current set of “hot spots,” which are currently at peak, subside. I roughly estimate the following: for August, 5.4%; September, 4.0%; October, 2.1%. On the day you go to the polls to vote for either Orange Man or Senator Senex, by my estimate, 62% of the country will be immune to COVID-19, which is close to herd immunity.
And yes, there is uncertainty here, but the analysis appears reasonable, based on the number so far tested and the numbers found to test positive. It also matches what a reasonable person should expect from this respiratory disease.
Of course, because it suggests we have a lot to be optimistic about the Wuhan virus, this analysis must be dismissed immediately, out of hand. It just can’t be right. We are all gonna die from COVID-19 and that’s it.
According to the university consortium building the Thirty Meter Telescope (TMT), they will make no attempt to begin construction until the end of winter in 2021.
According to the official spokesman, the consortium remains committed to building the telescope in Hawaii on Mauna Kea, but I do not see how it will ever happen. The present Democratic government supports the protesters, and there is no chance that government will ever be voted out of power.
Based on this information, I do not think TMT will ever be built, anywhere.
The new colonial movement: The United Arab Emirates first interplanetary probe, its Hope Mars Orbiter, was successfully launched by a Mitsubishi H-2A rocket today from Japan, and is now on its way to Mars.
It will arrive in February 2021, when it will attempt to inject itself into orbit, where it will then be used to study the Martian weather.
The leaders in the 2020 launch race:
16 China
10 SpaceX
7 Russia
3 ULA
3 Japan
The U.S. still leads China in the national rankings, 17 to 16.
