Issue with thermometers on Parker Solar Probe

8:56 am

As NASA prepares the Parker Solar Probe for its summer launch, engineers are reviewing an issue with the spacecraft’s thermometers.

As those preparations continue, officials are studying problems with devices known as platinum resistance thermometers that are part of the spacecraft’s thermal control system. Those devices have suffered a higher-than-expected failure rate, according to a presentation at an April 5 meeting of NASA’s Heliophysics Advisory Committee.

The thermometers are lightweight, highly sensitive temperature sensors used to help provide feedback to the spacecraft’s cooling system and solar arrays, NASA spokesman Dwayne Brown said April 9. “We put all spacecraft through a rigorous test program to make sure all systems are working as designed and it is normal for a test program to uncover issues.”

“The team is looking very carefully at whether any change is needed,” Peg Luce, acting director of NASA’s heliophysics division, said at the meeting. The issue, she said, was debated “quite significantly” at a review last week to approve the shipment of the spacecraft to Florida, including whether to delay that shipment to study the problem. “There are certain, possible fixes if we need to fix something that could be done at the Cape, so the decision was to go ahead and ship,” she said.

This issue is especially critical as the spacecraft is intended to fly as close as four million miles from the Sun. If these thermometers fail too easily, the spacecraft will not be able to monitor its temperature properly, and it will likely fail much sooner than planned.

China successfully launches three military satellites

8:47 am

The launch race: China today successfully launched three military satellites, using its Long March 4B rocket.

As is typical of Chinese military launches, no information was released about the satellites, and there was no publicity about the launch prior to liftoff. This launch however puts China ahead of the U.S. in total launches in 2018, 11 to 10. The leaders in the 2018 launch standings are as follows:

11 China
7 SpaceX
3 Japan
3 Russia
3 ULA
3 Europe

Europe’s Trace Gas Orbiter achieves operational orbit around Mars

8:33 am

After a year of aerobraking to lower its orbit, the European Space Agency’s Trace Gas Orbiter has reached its planned orbit around Mars, and is about to begin studying the red planet’s atmosphere.

The primary goal is to take a detailed inventory of trace gases – those that make up less than 1% of the total volume of the planet’s atmosphere. In particular, the orbiter will seek evidence of methane and other gases that could be signatures of active biological or geological activity.

On Earth, living organisms release much of the planet’s methane. It is also the main component of naturally occurring hydrocarbon gas reservoirs, and a contribution is also provided by volcanic and hydrothermal activity. Methane on Mars is expected to have a rather short lifetime – around 400 years – because it is broken down by ultraviolet light from the Sun. It also reacts with other species in the atmosphere, and is subject to mixing and dispersal by winds. That means, if it is detected today, it was likely created or released from an ancient reservoir relatively recently. Previous possible detections of methane by ESA’s Mars Express and more recently by NASA’s Curiosity rover have been hinted at, but are still the subject of much debate.

The Trace Gas Orbiter can detect and analyse methane and other trace gases even in extremely low concentrations, with an improved accuracy of three orders of magnitude over previous measurements. It will also be able to help distinguish between the different possible origins. [emphasis mine]

The highlighted sentence is important. Pinpointing a region where methane is concentrated will allow scientists to better understand where it is coming from, and what is causing its release. It could be microbiological life, but it also could be from active volcanic processes. Finding either or both would be significant, to put it mildly.

Two investigations blame Northrop Grumman for Zuma failure

2:18 pm

Two independent investigations have now placed the blame for the failure of the classified Zuma satellite to reach orbit on Northrop Grumman, not SpaceX.

Two independent investigations, made up of federal and industry officials, pointed to Northrop’s payload adapter as the cause of the satellite’s loss, the report said, citing people familiar with the probes. The payload adapter is a key part of deploying a satellite in orbit, connecting the satellite to the upper stage of a rocket.

…The investigations tentatively concluded that onboard sensors did not immediately communicate to ground systems that the satellite did not separate from the rocket, according to the Journal. Unbeknownst to officials at the time, the planned return of the rocket’s upper stage — a method of disposal to avoid adding space debris around the Earth — brought the satellite back down with it. By the time the satellite separated from the rocket it was too late, putting Zuma too low in orbit to save, according to the report.

I still have a nagging suspicion that Zuma actually did reach orbit, and this entire story that it never separated from the upper stage is all a disinformation campaign to help distract people from the satellite’s existence in orbit. At the same time, by this time I don’t put much faith in my own suspicions. These two reports appear to settle the matter.

Sunspot update for March 2018: the sun crashes!

11:49 am

It surely looks like the solar minimum has arrived, and it has done so far earlier than expected! On Sunday NOAA posted its monthly update of the solar cycle, covering sunspot activity for March 2018. Below is my annotated version of that graph.

March 2018 was the least active month for sunspots since the middle of 2009, almost nine years ago. In fact, activity in the past few months has been so low it matches the low activity seen in late 2007 and early 2008, ten years ago when the last solar minimum began and indicated by the yellow line that I have added to the graph below. If the solar minimum has actually arrived now, this would make this cycle only ten years long, one of the shortest solar cycles on record. More important, it is a weak cycle. In the past, all short cycles were active cycles. This is the first time we have seen a short and weak cycle since scientists began tracking the solar cycle in the 1700s, following the last grand minimum in the 1600s when there were almost no sunspots.

Homeland Security to track journalists and bloggers in the media

9:42 am

We get our own KGB! Homeland Security has requested bids on providing a database that will continually track of activities of “journalists, editors, correspondents, social media influencers, bloggers etc.”

The DHS’s “Media Monitoring” plan, which was first reported by FedBizOpps.gov, would give the contracting company “24/7 access to a password protected, media influencer database, including journalists, editors, correspondents, social media influencers, bloggers etc.” in order to “identify any and all media coverage related to the Department of Homeland Security or a particular event.”

The database would be designed to monitor the public activities of media members and influencers by “location, beat and influencers,” the document says.

The chosen contractor should be able to “present contact details and any other information that could be relevant including publications this influencer writes for, and an overview of the previous coverage published by the influencer.”

A Homeland Security official claimed this was “standard practice” but he was either ignorant or lying. This is a new tool for spying on journalists while also obtaining information that can be used against them for political purposes. Any government agency that had proposed such a thing to past American generations would have found itself very quickly shut down. The idea of the government tracking individuals reporting the news would have been considered disgusting and a violation of numerous amendments in the Bill of Rights.

Today however, not so much. We need our KGB, and we are going to get it, come hell or high water!

An added note: Most of the outrage about censorship and spying that we see today in the press is focused on Google, Facebook, and the unsavory stuff these big software companies are doing. These are private efforts, however, and there is a simple solution to stopping their bad behavior: Their customers have to find a competitor who doesn’t do it and switch services.

Unfortunately, we instead have increasing calls for the government to regulate and even break up these companies. This is exactly not what we should do, as it will only place more power in that government. If anything, it will provide justification for the government to spy on journalists and regulate them, as illustrated by this newly proposed law in fascist California.

“If you have wrongthink, you will not be allowed.”

1:34 pm

The fascist, intolerant, and oppressive nature of today’s leftist culture has now gotten so bad that The Atlantic, a liberal publication long considered a reasonable intellectual voice from the left, can no longer tolerate for more than two weeks the hiring of a conservative, even though that conservative, Kevin Williamson, was also a vehement opponent of Donald Trump.

The quote that forms the title of this essay however comes not from the above Williamson story, but from a cogent essay by Ben Domenech, publisher of The Federalist about that intolerant leftist culture. As he says,

This story [Williamson’s firing] is a predictable continuation of the left’s ownership not just of media but indeed of all institutions. It is depressing. It is predictable. And it is where we are as a country now. It is not confined to the realm of ideas. Eich, Damore, Williamson and others are subject to blacklists and HR reports and firing in every arena of industry and culture. If you have wrongthink, you will not be allowed for long to make your living within any space the left has determined they own – first the academy, then the media, then corporate America, and now the public square. You will bake the cake, you will use the proper pronoun, and you will never say that what Planned Parenthood does is murder for hire, and should be punished as such under the law.

As Domenech notes, Williamson’s firing is only one example of a legion of similar stories. There is the fascist intolerance of modern academia for example. Or we can talk about the hateful scapegoating of innocent NRA members, blaming them for a murderer’s violence merely because they wish to defend their Constitutional rights as specifically outlined in the Bill of Rights.

Or maybe we should mention the hate and violence committed against children and students, merely because they either wear a “Make America Great Again” t-shirt or carry signs supporting Trump.

I wish these were only isolated examples. They are not. For most of the second half of last year I was able to post weekly updates listing anywhere from six to several dozen new stories describing this hateful leftist culture. Here are just a few more that I gathered in mid-March but found too depressing to report at the time:

A detailed analysis of the recent seemingly pro-Israel remarks by the Saudi leader

9:07 am

Link here. The analysis takes a close look at what Saudi Crown Prince Muhammad bin Salman really said about Israel’s right to exist, and found that, while much of what he said was hopeful, it was couched in enough vagueness that no one should celebrate too wildly.

In short, Muhammad said nothing revolutionary. He bore no glad tidings of a strategic shift in the Saudi Islam or in the manner that the Saudis relate to the world, including the Jews.

Which brings us back to the main question. What did we learn from this interview? The most significant thing that came out of the interview is that Saudi Arabia’s crown prince is very keen to cooperate with the US and with Israel in everything related to defeating what he refers to as the “triangle of evil.”

The three sides of his triangle are Iran, the Muslim Brotherhood, and the terrorist groups the Muslim Brotherhood has spawned, including al-Qaeda and Islamic State.

Saudi Arabia is still an Islamic country run by the corrupt and violent Arabian culture. As noted elsewhere in the article,

The problem is that Muhammad’s regime is built on shaky foundations. Muhammad instigated a blood feud with powerful forces within his family when he carried out a string of arrests last year. Among those arrested were several prominent princes.

Rhode [a Middle East expert] explains that the Saudi ruling clan divvied up the organs of government among branches of the family. For instance, one branch controls the Defense Ministry, another controls the Education Ministry, and so on down the line.

“In the Islamic world, humiliation is worse than death,” Rhode notes. “When Muhammad arrested the other princes, he humiliated them,” Rhode says. “And they will never forgive him. They will wait for the day they can exact revenge for their humiliation even if it only comes when their great-grandchildren have succeeded them.”

We cannot trust them very much, but we can take advantage of their internal conflicts to push them in a more reasonable direction.
