Witchhunt against Northrop Grumman employee because of his private opinions

11:03 am

The new blacklist: The modern McCarthyism goes after a Northrop Grumman employee because it doesn’t like his private political opinions.

Aerospace giant Northrop Grumman Corp. said it is taking “immediate action” to look into a report that one of its engineers is part of a white nationalist group and was involved in violent brawls during last year’s Unite the Right rally in Charlottesville, Va.

Investigative news outlet ProPublica and PBS documentary program “Frontline” identified Michael Miselis, 29, as a member of the Rise Above Movement, which they described as a Southern California group that “expresses contempt for Muslims, Jews and immigrants.” The Southern Poverty Law Center civil rights group describes the Rise Above Movement as a hate group, and categorizes it specifically as a white nationalist group.

Read the article. The attitude of the author will chill you to the bone.

This is not an endorsement of this employee’s political opinions. In fact, a close read of the article suggests that this person might not even be the person with such opinions. Nonetheless, in a free country one should have the right to any opinions, and those opinions, no matter how vile, should not prevent you from earning your living. Furthermore, a free country will allow you to express those opinions, freely, without threat of harm.

It does not appear we live in such a country at this time. This individual has been identified as having opinions the social justice warriors of the left do not like, and thus he must be stoned to death. I am surprised they haven’t yet gotten the pitchforks and torches out and lynched him.

Astronomers dispute existence of galaxy without dark matter

10:40 am

The uncertainty of science: A new analysis by astronomers disputes the conclusion of different astronomers earlier this year that they had found a galaxy that lacked any dark matter.

The original paper from March based its stunning claim of a dark-matter-free galaxy on the way clusters of stars moved through the thin, diffuse galaxy called NGC1052–DF2: They appeared to move at exactly the speed Einstein’s equations of general relativity would predict based on the visible matter (so, slower than they would if the galaxy held dark matter).

This new paper on arXiv suggested otherwise: First, the authors pointed out that NGC1052–DF2 was already discovered way back in 1976 and has previously been referred to by three different names: KKSG04, PGC3097693 and [KKS2000]04.

Then, using those names and then finding all the available data on the galaxy, the researchers argued that the researchers from the March paper simply mismeasured the distance between that galaxy and Earth. This means the galaxy is probably much closer to us than the original researchers thought.

Astronomers calculate the mass of galaxies based on the objects’ brightness and distance. If the galaxy examined in the paper is closer to Earth than previously thought, then its dimness means it’s also much less massive than researchers thought. And at the newly calculated, lighter mass, all the other features of the galaxy make a lot more sense, the researchers in the new paper said. Its globular clusters aren’t moving slowly because they’re in some strange dark matter-desert; instead, they’re moving at the regular speed for a very lightweight galaxy, the arXiv authors said.

To put it bluntly, the astronomers don’t have enough solid data to decide this issue one way or the other. Moreover, the dispute indicates once again that the whole dark matter theory itself is based on very limited data with large margins of error. It might be the best theory we’ve got to explain the data we have, but no good scientist takes it too seriously. We just don’t know enough yet.

Kepler on verge of death

10:04 am

The Kepler space telescope is now almost out of fuel, and scientists have ceased science observations to devote the telescope’s last days downloading its last 51 days of data.

The telescope lasted far longer than planned, and discovered thousands of exoplanets. Its archives will be producing new discoveries for decades. And a new exoplanet space telescope, TESS, is already in orbit to take over.

Searchers find fragment of asteroid that hit Earth June 2nd

10:00 am

Researchers and local park volunteers in Botswana’s Central Kalahari Game Reserve on July 8 announced the discovery of a fragment from an asteroid that hit the Earth June 2 only eight hours after it was discovered.

“The biggest uncertainty we faced was to determine where exactly the meteorites fell,” says Peter Jenniskens a subject expert of the SETI Institute in California, who traveled to Botswana to assist in the search. He teamed up with Oliver Moses of the University of Botswana’s Okavango Research Institute (ORI), to gather security surveillance videos in Rakops and Maun to get better constraints on the position and altitude of the fireball’s explosion. Team member Tim Cooper of the Astronomical Society of Southern Africa calibrated videos to the south.

After disruption, the asteroid fragments scattered over a wide area, blown by the wind while falling down. Calculations of the landing area were done independently by the NASA-sponsored group headed by Jenniskens, as well as by Esko Lyytinen and Jarmo Moilanen of the Finnish Fireball Network. These calculations were defining the fall area well enough to warrant the deployment of a search expedition.

The first meteorite was found after five days of walking and scouring a landscape of sand, thick tall grass, shrubs and thorn bushes by a team of geoscientists from the Botswana International University of Science and Technology (BUIST), the Botswana Geoscience Institute (BGI) and from ORI, guided by Jenniskens. The Botswana Department of Wildlife and National Parks granted access and deployed their park rangers to provide protection and participate in the search. BUIST student Lesedi Seitshiro was first to spot the stone.

This is only the second time in history that a small asteroid observed in space was recovered following its impact on Earth.

I have amateur astronomer friends who attempted to do this exact thing, here in Tucson. We actually went out one day hunting for a meteorite they had tracked, but were unsuccessful in finding anything. To have had success we would have likely required more search time and a better constraint on the asteroid’s landing zone.

India tests launch abort system for its own manned capsule

9:31 am

India on July 5 successfully tested its own launch abort system for use on its own manned capsule.

The test was over in 259 seconds, during which the crew escape system along with crew module soared skyward, reached an altitude of nearly 2.7 km, swerved over the Bay of Bengal and floated back to Earth under its parachutes about 2.9 km from Sriharikota.

A video showing excerpts of the test can be viewed here.

India has not yet fully committed to building a manned capsule, but they have been moving forward on testing for several years now, and I expect them to make a commitment within the next year. In fact, I think it likely that India will be the fourth nation, after Russia, the U.S., and China, to launch its own astronauts into space on its own spacecraft.

Back from Belize

9:21 am

Home at last! The week of caving in Belize was somewhat exhausting, which is why I only had time to post on the one day I took time off. It was a great success however. We managed to survey all of my goals for the week, which essentially covers the most important parts of the cave. We also had a number of local cave guides participate so that they could learn cave surveying and hopefully continue the survey on their own. The map will get finished much faster if the locals mapped it.

More important, it is their cave. They really are the ones that should do it.

I will be posting throughout the day, catching up.

AT&T: How to Use the Dial Phone

6:01 pm

An evening pause: I would not be surprised if some of the younger readers of Behind the Black would need the instructions in this silent film in order to properly use a rotary phone.

Introducing any new technology requires instruction. This was strange stuff to homeowners in 1927, but a great improvement over party line phones that required an operator to do the dialing. And this was cutting edge then, and a symbol of the future.

Hat tip Jim Mallamace.

An evening pause: As John Adams predicted right after ratification of the Declaration of Independence, Independence Day “…ought to be solemnized with pomp and parade, with shows, games, sports, guns, bells, bonfires, and illuminations from one end of this continent to the other, from this time forward forever more.”

It was a declaration for freedom. And even if freedom dies here in this country, the idea will live on, as long as the individual soul of any human beats strong.

As an aside, check out this old post, before I moved to Arizona, when I used to participate on a fireworks team.

The Declaration of Independence

12:49 pm

Link here. I think today it is worthwhile to read the whole thing, even though it is the first sentence in the paragraph below that is most often quoted. The following sentences are just as important, though less frequently quoted.

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness. — That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, — That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness. Prudence, indeed, will dictate that Governments long established should not be changed for light and transient causes; and accordingly all experience hath shewn that mankind are more disposed to suffer, while evils are sufferable than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same Object evinces a design to reduce them under absolute Despotism, it is their right, it is their duty, to throw off such Government, and to provide new Guards for their future security.

All governments tend toward oppression. Power-hungry individuals always act to use the power government wields for their own corrupt purposes. Thus, Jefferson was correct above when he said that, when those abuses become bad enough, it is the right of the citizen “to throw off such government.”

We sadly might be approaching a time in the U.S. where such action will once again be necessary.

Day off on the Fourth of July in Belize

10:07 am

After three hard days of caving, I decided to take the Fourth of July off to rest, relax, sit by the pool, and catch up with the news in space and elsewhere.

The cave surveying has been going well, but we have been trying to finish the survey of the cave’s largest room, and have found it daunting. Basically we have four survey teams spread out across the room’s width, marching forward to cover the entire passage. Since the room is never less than 150 feet wide, this takes time. After three full days of work, we finally reached the far wall yesterday, though we still have significant clean-up in many places.

Nor is this the cave’s only passage. We have several other areas that need survey, many of which I hope the local cavers will do after we Americans go home on Saturday.

More launch delays from Russia

10:00 am

Russia has decided to delay one of three commercial Soyuz rocket launches to 2019 due to unspecified “readiness” issues.

The launch of Soyuz-ST launch vehicle with a European satellite was initially scheduled for October 6, a source in the aerospace industry told Interfax. “However, evaluating relevant conditions and the launch vehicle’s readiness, the decision was made to move the launch to November 6,” the source said.

In all, three Russian launch vehicles were expected to take off from the Kourou Space Center by the yearend. Italy’s CSG-1 satellite was scheduled to be launched in November, which was to be followed by the launch of OneWeb’s pilot mini-satellites. Due to the delay of the European weather-forecasting satellite’s launch, the launch of two more rockets from Kourou was endangered. “One of the three launches has to be postponed until next year. This is most likely to be Italy’s CSG-1 satellite. However, a lift-off of satellites under the contract with OneWeb may be adjourned,” he said.

In addition, there was this story (behind a paywall) that noted that the only Proton-M launch in 2018 will also be delayed until 2019.

While such delays in rocket launches are not unusual and are an accepted part of the business, these delays for Russia do not help them. The technical problems in recent years that have caused many launch failures, combined with these delays, will further encourage their international customers to go elsewhere.

Justice Department lets Imran Awan walk

8:42 am

The swamp wins! The Department of Justice this week made a plea deal with former House IT specialist Imran Awan, allowing him to walk away free on probation.

Federal prosecutors on Tuesday entered a plea deal with Imran Awan, ringleader of the Pakistani family at the center of the House IT scandal, and in the process defied President Donald Trump and explicitly contradicted congressional investigators who described the group as “an ongoing and serious risk to the House of Representatives.” In a statement to the court, Department of Justice (DOJ) prosecutors said they “found no evidence that [Imran] illegally removed House data from the House network or from House members’ offices, stole the House Democratic Caucus server, stole or destroyed House information technology equipment, or improperly accessed or transferred government information.”

The prosecutors told the court they would not object if Awan received probation, and they agreed to drop fraud-related charges against his wife. The deal means Awan is free to leave the country and won’t face prosecution in connection with his congressional employment.

The DOJ announcement flew directly in the face of Trump’s June 7, 2018, tweet saying, “Our Justice Department must not let Awan & Debbie Wasserman Schultz off the hook. The Democrat I.T. scandal is a key to much of the corruption we see today. They want to make a ‘plea deal’ to hide what is on their Server. Where is Server? Really bad!”

Trump is by law the boss of the Department of Justice, but prosecutors there continue to act as if they are in charge and the president is merely an annoyance who must be bypassed. Moreover, these prosecutors appear to have been working entirely in league with House Democrats to squash this investigation, from the beginning. Because Trump did not take control, they have now succeeded.

I should add that this case demonstrates clearly that Trump is not really acting to drain the swamp. He is cleaning out a few select agencies (EPA), but allowing the rest to remain, with the worst being Justice and the FBI. Trump is essentially a transitional president. The question remains: What are we transitioning to? To me, it increasingly appears we are transitioning to the fall of our democratic government and the freedom it formerly gave to all citizens, equal before the law. And that I write this on Independence Day is more than tragic.

Virgin Orbit gets first launch license

7:54 am

Capitalism in space: Virgin Orbit has obtained its first launch license from the FAA.

They hope to fly this first orbital flight before the end of the summer. Previously they have announced launch contracts calling for commercial launches in 2019, which requires these test flights in 2018.

Either way, it appears that, as I predicted in 2016, Virgin Orbit will achieve its first operational flight ahead of Virgin Galactic, even though the latter has been in development more than twice as long.

Galaxies collide!

7:07 am

Using data from then space telescope Gaia, astronomers have identified evidence that 8 to 10 billion years ago the Milky Way collided with a dwarf galaxy.

The astronomers propose that around 8 billion to 10 billion years ago, an unknown dwarf galaxy smashed into our own Milky Way. The dwarf did not survive the impact: It quickly fell apart, and the wreckage is now all around us.

“The collision ripped the dwarf to shreds, leaving its stars moving in very radial orbits” that are long and narrow like needles, said Vasily Belokurov of the University of Cambridge and the Center for Computational Astrophysics at the Flatiron Institute in New York City. The stars’ paths take them “very close to the center of our galaxy. This is a telltale sign that the dwarf galaxy came in on a really eccentric orbit and its fate was sealed.”

It is thought that this dwarf galaxy was quite large for a dwarf galaxy.

A star that shoots cosmic rays

7:02 am

New data from the space telescope NuSTAR suggests that the giant star Eta Carina, expected to be a supernova sometime in the future, emits cosmic rays, some of which reach the Earth.

The cosmic rays are produced by shock waves resulting from the clash between the intense solar winds of the system’s two stars.

Go to the link to see a truly beautiful image of this star system. You will immediately see that it is a system exploding.

More close-up images of Ceres

6:48 am

On Monday the Dawn science team released more close-up images of Ceres, taken from Dawn’s final close orbit of the dwarf planet, with the focus of this release Occator Crater and its bright spots.

The current images now show numerous sections of Occator Crater from an altitude of 35 kilometers and with a resolution less than 5 meters per pixel. “The data exceeds all our expectations,” Dr. Andreas Nathues from the MPS, Framing Camera Lead Investigator, says. In the new images, the surface is now ten times better resolved than in the best images from the previous three years.

Impressive avalanches reveal themselves in the new views of the eastern wall of Occator Crater: there are clear signs that material has been recently moving down the slopes; some of it remains stuck halfway. Other images allow a close look at the interplay of bright and dark material in the eastern part of the crater. “We now hope to understand how the bright deposits outside the crater center came about – and what they tell us about Ceres’ interior,” says Nathues. Various analyses of the past years suggest that Ceres has a water-rich crust. Small impacts and landslides regularly expose ice at the surface, which produces a thin exosphere of water vapor.

I have posted some of these images previously, but there are several new ones at the link.
