India’s competitor for the the Google Lunar X-Prize, Team Indus, has exited the competition because it could not raise the funds needed to buy a launch on an Indian PSLV rocket.
It is unclear how this will effect Japan’s team, Hakuto, which was going to fly on the same rocket, mounted to the Team Indus lander. I suspect that their effort is over as well.
An online pubic program designed to allow ordinary people to use their computers to identify previously unknown prime numbers has found the largest so far, 23 million digits long.
It was discovered on December 26, 2017 by electrical engineer Jonathan Pace, and it initially took six days of non-stop number crunching to show that it was indeed a prime number. Pace was using a consumer-level PC running an Intel i5-6600 processor, and after it was identified it was then independently verified by other users, with a range of other programs and hardware setups.
China completed its first launch of 2018, launching two civilian high resolution Earth observation satellites.
The launch standings in 2018 is presently a tie between SpaceX and China. I expect it to be a neck and neck race between both for the rest of the year.
The first six mirror segments of the European Southern Observatory’s Extremely Large Telescope have been successfully cast.
These segments will form parts of the ELT’s 39-metre main mirror, which will have 798 segments in total when completed. The ELT will be the largest optical telescope in the world when it sees first light in 2024.
The 39-metre-diameter primary mirror of ESO’s Extremely Large Telescope will be by far the largest ever made for an optical-infrared telescope. Such a giant is much too large to be made from a single piece of glass, so it will consist of 798 individual hexagonal segments, each measuring 1.4 metres across and about 5 centimetres thick. The segments will work together as a single huge mirror to collect tens of millions of times as much light as the human eye.
The segments must now be cooled, then their surfaces ground and polished to the right shape. If all goes right, they will make more than 900 segments (with about a 130 as spares), manufactured to have the telescope operational by 2024.
Capitalism in space: Blue Origin has released a short video showing a recently completed successful static fire test of its BE-4 rocket engine.
You can see the test here. The article above actually doesn’t provide much information about the engine’s testing program, other than claiming that the company is ramping up its testing.
An evening pause: Performed live in 1996.
Hat tip Edward Thelen.
Anonymous sources are suggesting that the top secret government payload that SpaceX successfully placed in orbit two days ago might have been lost.
Very little is presently known. Statements from SpaceX suggest that its Falcon 9 rocket worked perfectly, which would suggest the problems occurred after second stage separation. However, one source seems to suggest otherwise.
Until I get more information, I am therefore still counting this launch as a success for SpaceX.
The precipitous decline in sunspots continues. While November 2017 remains the most inactive month for sunspots since the middle of 2009, December was a very close second.
Below is my annotated version of NOAA’s monthly update of the solar cycle, covering sunspot activity for December, which they posted on Sunday.
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.
The graph on the right, produced by SILSO (Sunspot Index and Long-term Solar Observations) on December 31, shows only 14 days during the month when there were sunspots active on the Sun’s visible hemisphere. This is only four more days then seen in November. And like November, the few sunspots were weak, resulting in tiny sunspot numbers total.
The first graph above illustrates how weak this on-going sunspot cycle has been. While the curve most closely matches the 2007 weak prediction of half the solar science community, it has one very notable difference. The actual ramp up to solar maximum started two years later than predicted, even though it appears to be ending when that prediction expected. The result is a very very short solar cycle, something that has historically always been associated with very active and intense sunspot activity. Instead, this short cycle has only seen weak activity, generally below all the predictions.
All signs continue to point to an early arrival of solar minimum. They also suggest that the next maximum will also be weak, and might even not come at all, as some solar scientists have proposed. Instead, we might be heading toward another Grand Minimum, with no significant sunspots for decades.
So, is it cold outside right now? Well, that’s weather, not climate. Nonetheless, there is a lot of circumstantial evidence that few sunspots correspond with a cooling climate on Earth. (The last grand minimum occurred in the 1600s, during what was called the Little Ice Age.) There is even some preliminary evidence to suggest that cosmic rays might be a cause. (Watch the video at the end of this link.).
Whether any of this will happen however remains unknown. We will need to wait to find out.
In November over a period of two weeks the Mars Odyssey team posted ten images of Pavonis Mons, the smallest of the aligned three giant volcanoes just to the east of Olympus Mons, the largest known volcano in the solar system. I then made all of those images available in a single link, with some analysis.
They have now done the same thing for the southernmost (and possibly the most interesting) of those three aligned volcanoes, Arsia Mons. From the first image below:
Arsia Mons is the southernmost of the Tharsis volcanoes. It is 270 miles (450km) in diameter, almost 12 miles (20km) high, and the summit caldera is 72 miles (120km) wide. For comparison, the largest volcano on Earth is Mauna Loa. From its base on the sea floor, Mauna Loa measures only 6.3 miles high and 75 miles in diameter. A large volcanic crater known as a caldera is located at the summit of all of the Tharsis volcanoes. These calderas are produced by massive volcanic explosions and collapse. The Arsia Mons summit caldera is larger than many volcanoes on Earth.
In other words, you could fit almost all of Mauna Loa entirely within the caldera of Arsia Mons.
The image on the right above is the master index, annotated by me to show the area covered by each image. The images can accessed individually below.

The law is such an inconvenient thing: The federal judge in the Cliven Bundy case has dismissed all charges against Bundy and three others, citing “flagrant prosecutorial misconduct.”
I think the article provides a fair and good summary of the history behind these events, which are complex, with no one entirely innocent. Overall my sympathies tend to favor Bundy, as the problem began with the take-over of his family’s traditional grazing lands a long time ago by the federal government.
Link here. The CFPB was established under the Dodd-Frank law signed by Obama under a framework that one court has already ruled is unconstitutional.
[A]s is common in Washington, the vague language used to craft that law gave regulators wide latitude and the bureau emerged in the Obama administration as a powerful force in the regulatory state.
“There’s strong evidence that the CFPB was pursuing Obama administration tactics and priorities, even if it was not directly coordinating with other Obama-run agencies,” said John Berlau, a scholar with the conservative Competitive Enterprise Institute. As an example of such connections, Berlau pointed to Operation Choke Point, a 2013 Justice Department initiative during which the CFPB pursued payday lenders while prosecutors focused on banks dealing with those businesses or gun retailers. “Like other Obama regulators, the CFPB attempted to make law through administrative maneuvers,” Berlau told RCI. “Yet the CFPB’s abuses of process exceeded even those of other Obama administration bureaucracies due to the bureau’s unique lack of accountability.”
That lack of accountability was one of the reasons a three-judge panel on the D.C. Circuit Court of Appeals ruled the CFPB an unconstitutional entity in October 2016 – a decision that awaits an en banc ruling from the Appeals Court.
The article outlines how the CFPB has used its vague regulatory powers during the Obama administration to begin open investigations into numerous businesses, not based on any suspected crimes but as a weapon of the Obama administration against businesses it did not like.
The bad part of this story is that there appears no effort by the Trump administration to shut down this out-of-control agency. Instead, it is trying to “rein” it in. Meanwhile, this agency, which according to the law that created it, can spend money without Congressional approval, and is doing so at rates that would make billionaires like Trump blush: A New CFPB Scandal – Cost Overruns for Its New Lux Headquarters
Original cost estimates for the CFPB’s renovation were estimated at $55 million, but the bureau ran up the proposed cost to $216 million. The Federal Reserve Inspector General rejected the proposal in 2014, saying there was no “sound basis” for the figure.
The world is faced with threats of nuclear and chemical attacks from North Korea. Iran is hit by protests that might escalate into all out civil war. Islamic terrorist attacks have now become almost routine. And in the U.S. there appears to be corruption at the highest levels of the FBI and the Department of Justice, while at the same time the federal government has produced a national debt exceeding $20 trillion, with more debt on the way.
Have any of these significant stories been the primary focus of our American media, from either side of the political spectrum?
An objective look at the culture of today’s press says no. Even as the leftist American mainstream media continues to focus its energies on petty and ineffective attacks of Donald Trump, too many journalists on the right unfortunately appear to be diving right in to join them with their own petty counter-attacks. The result is a press that spends the bulk of its time on irrelevant stories of partisan bickering that have little substance or importance.
In the last week of 2017 we had one particularly acute example of this. First a mainstream liberal news source pushed an absurdly trivial story in a shallow effort to discredit Donald Trump. This was then followed by a frenzied and as-shallow response from the conservative press. I want to showcase both, not merely to illustrate how weak the original story was (which is obvious on its face), but to also point out the childishness of the response.
I must add that everything written in every one of the news sources that I will cite below appears to be 100% accurate. My point here isn’t to highlight examples of error-filled news reporting — which these days mostly comes from left leaning sources overwhelmed by their blind hatred of Trump — but to illustrate reporting from both sides that hardly rises above the level of a five year old, and is thus completely inconsequential.
From CNN: Truck blocks cameras from filming Trump on golf course.
Apparently the day before CNN had managed, by peering through some bushes on the edge of the Trump International Golf Club in Florida, to videotape President Trump playing some golf. When they came back the next day a white truck now blocked their view. This then became a big scandal for CNN, with the cable network then spending gobs of time every hour for the next few days investigating the truck and following up on this terrible act of corruption, obviously part of the evil Trump administration’s effort to cancel the First Amendment and to silence the press! Much of the leftwing media piled on as well. Below are some of CNN’s coverage, as well as a bit of that liberal news pile on.
