No rotational light curve from Ultima Thule?

Data from New Horizons as it is quickly approaching Ultima Thule has found that even though the object is expected to be oblong or even two objects it has shown absolutely no variation in light as it rotates.

Even though scientists determined in 2017 that the Kuiper Belt object isn’t shaped like a sphere – that it is probably elongated or maybe even two objects – they haven’t seen the repeated pulsations in brightness that they’d expect from a rotating object of that shape. The periodic variation in brightness during every rotation produces what scientists refer to as a light curve.

“It’s really a puzzle,” said New Horizons Principal Investigator Alan Stern, of the Southwest Research Institute. “I call this Ultima’s first puzzle – why does it have such a tiny light curve that we can’t even detect it? I expect the detailed flyby images coming soon to give us many more mysteries, but I did not expect this, and so soon.”

They have several theories, all implausible, to explain this. It could be they are looking at the object’s pole. Or maybe a dust cloud or numerous tumbling moons surround the object and hide the light variation.

Fortunately, we shall have an answer to this mystery in less than two weeks, when New Horizons zips past.

Trump’s decision to leave Syria

Link here. A less favorable analysis can be read here.

It is very clear, as the first article notes, that Trump was making the same decision as Reagan did back in the earlier 1980s in Lebanon. You either fight a war hard, without hesitation, aiming for complete victory, or you get out. Anything in between wastes lives, money, and only makes a bad situation worse. Reagan in Lebanon chose the latter. I suspect Trump today in Syria was doing the same.

The bad part of this is that our political leadership since 1945 had routinely chosen the middle, wishy-washy route, which has failed time after time and left us where we are today. This Babylon Bee satire article, “Trump Criticized For Breaking With Longstanding American Tradition Of Remaining In Middle Eastern Countries Indefinitely”, captures perfectly the insane approach to foreign policy by our elitist culture that they have followed for decades. It is not that they don’t want to make positive changes and help America’s strategic position globally, it is that they have no desire to make the real and possibly very violent commitments necessary to accomplish their goals. They instead do the insane thing, doing the same indecisive thing over and over, even though doing that thing is guaranteed to fail, every single time.

Trump at least made a firm decision, that in the short run will likely save American lives and money. In the long run, however, we continue to put our heads in the sand. We do not want to deal with the violent evil in the world, both at home and abroad, that is gaining power and dominance. This weakness is eventually going to bite us, badly.

Hat tip to Kirk Hilliard for prodding me to report on this story. I admit to being lax about reporting it. Since the election, my desire to read hard news has waned somewhat, though it is probably still far more extensive than most people. I see very bad things coming, and have found little in the news to reassure me that I am wrong. And I hate reporting bad and depressing news. I saw this story in a number of news outlets but just didn’t have the urge to read and report it.

CNN’s “Journalist of the Year” fired for fabricating stories

Modern journalism: CNN’s “Journalist of the year” for 2014 has been fired for fabricating stories by the German magazine Der Spiegel.

Claas Relotius, a reporter and editor, admitted to fabricating parts of at least 14 stories following the magazine’s internal investigation. The publication said the issue “marks a low point in the 70-year history of Der Spiegel.”

…The reporter contributed around 60 articles to Der Spiegel, one of the leading German magazines for investigative reporting. He previously worked for other publications in Europe and won awards such as CNN Journalist of the Year in 2014.

The fabricated articles include a phone interview with the parents of free agent NFL player Colin Kaepernick and a story about an American woman who claims to have volunteered to witness the executions of death row inmates.

Relotius also drew the fury of locals in Fergus Falls, Minn., after spending three weeks in town and fabricating facts, characters and quotes from people in an effort to portray the town in a negative light. “What happened is beyond what I could have ever imagined: An article titled ‘Where they pray for Trump on Sundays,’ and endless pages of an insulting, if not hilarious, excuse for journalism,” wrote Michele Anderson and Jake Krohn who investigated Relotius’ Der Spiegel article about the town.

Both Anderson and Krohn went on to reveal that the article doesn’t contain any truth except for the town’s population, the average temperature, and names of the businesses or public figures. Nearly everything else, including a coal plant employee named Neil Becker, who doesn’t actually exist, or quotes from a restaurant employee, who was falsely called the owner of a restaurant and whose son was given a fictional illness, was made up.

It is clear from the above that this reporter’s fakery was designed to confirm the false narrative of our elitist intellectual society that believes that everyone in mid-America who might have voted for Trump is an idiot and a fool with the education of a turnip. No wonder CNN considered him a top journalist, since this is the same fakery I see repeatedly on that network.

The article notes other similar cases of journalist corruption from the Washington Post, the New York Times, and the New Republic. The important historical context of these stories — besides that they all occurred at liberal outlets — is that they were once rare. When Janet Cooke was caught fabricating facts in 1981, she was almost a first. Such a thing had been unheard of in the top journalist world for literally decades. Previously, if you got a job at a place like the Washington Post it was because you knew how to do the job. Cooke indicated that this standard had failed, and it is clearly failing more and more routinely, at numerous so-called top liberal news outlets, in the subsequent years.

Worse, this is only the tip of the iceberg. Trump’s accusations of fakery in the liberal press resonates with people because it contains a substantial element of truth. It also resonates because these liberal outlets have very obviously done nothing to correct their errors and false reporting. Bad reporters continue to work for them, even after they have been found to make egregious errors, including plagiarism.

InSight installs seismometer on Martian surface

InSight has successfully placed its first instrument, its seismometer, on Martian surface.

They aren’t yet ready to start gathering data, however.

In the coming days, the InSight team will work on leveling the seismometer, which is sitting on ground that is tilted 2 to 3 degrees. The first seismometer science data should begin to flow back to Earth after the seismometer is in the right position.

But engineers and scientists at JPL, the French national space agency Centre National d’Études Spatiales (CNES) and other institutions affiliated with the SEIS team will need several additional weeks to make sure the returned data are as clear as possible. For one thing, they will check and possibly adjust the seismometer’s long, wire-lined tether to minimize noise that could travel along it to the seismometer. Then, in early January, engineers expect to command the robotic arm to place the Wind and Thermal Shield over the seismometer to stabilize the environment around the sensors.

They plan on deploying the heat probe (which will drill down about 16 feet) in January.

Curiosity’s future travels

MRO image of Curiosity's future travels

In the December release of images from the high resolution camera on Mars Reconnaissance Orbiter (MRO), there was one image entitled “Monitor Region Near Curiosity Rover.” To the right is a reduced, cropped, and rotated section of that image, annotated by me to show Curiosity’s future planned route (indicated by the yellow line). If you click on the image you can see the untouched full resolution version.

Curiosity’s journey has not yet brought it onto the terrain shown in this image. (For the overall context of Curiosity’s travels, see Pinpointing Curiosity’s location in Gale Crater.) The rover is right now just off the left edge of the photograph, on the white ridge dubbed Vera Rubin Ridge visible in the uppermost left. This week it completed the last planned drill sampling on that ridge, and it will soon descend off the ridge and begin heading along the yellow route up the mountain. The white dots along its future route are the locations of recurring slope lines, believed to be seasonal seeps of brine coming from below and causing gentle landslides that darken the surface. As you can see, they hope to get very close to the first seep, and will observe the second from across the canyon from a distance of about 1,200 feet.

The peak of Mount Sharp is quite a distance to the south, far beyond the bottom of the photograph. Even in these proposed travels the rover will remain in the mountain’s lowest foothills, though the terrain will be getting considerably more dramatic.

Below is a full resolution section of the image showing the spectacular canyon to the south of that second seep. This is where Curiosity will be going, a deep canyon about 1,500 feet across and probably as deep, its floor a smooth series of curved layers, reminiscent of The Wave in northern Arizona. The canyon appears to show evidence of water flow down its slopes, but that is unproven.

SpaceX raises a half billion for its Starlink satellite constellation

Capitalism in space: SpaceX has raised $500 million in investment capital to help fund its planned Starlink internet constellation expected to have just under 12,000 satellites in orbit.

I wonder if SpaceX will also be using this money for the development of Super Heavy/Starship. The article implies no, but the article also does not have access to the specific terms of the deal.

I also notice the interesting timing of this story today and yesterday’s story about how the Starlink satellites pose a threat of hitting people when they get de-orbited. Timing like this is rarely an accident. There are a lot of competitors to SpaceX who do not want it to succeed, and it would not surprise me if they are trying to throw a wrench in the operation to stop Starlink. A bad report like yesterday’s might cause big investors to back out.

BepiColombo begins first operational engine burn

The European/Japanese mission to Mercury has begun the first operational firing of its four ion engines, set to last for the next two months.

This might seem like a ridiculously long burn, since most conventional rocket engines fire for minutes, not months. These are ion engines, however, far more efficient but producing a very tiny acceleration. It takes a long time for their burns to accumulate a velocity change.
