July 30, 2019 Zimmerman Space Show podcast

David Livingston has now made the podcast of my two hour appearance on the Space Show available. You can either listen or download the podcast here.

Another show. I will admit when the conversation shifted to the federal budget and the desires of space geeks to have lots of money for space, regardless of the debt it creates, I got a little hot. I then referenced this essay by me from November 2011: NASA, the federal budget, and common sense.

Everything I wrote then still applies. Worse, no one in our federal government has attempted any of it. The federal budget continues to rage out of control, and what NASA spends continues to be spent poorly.

Democrats fire six people because they are white

The racist party: In order to hire more minorities (despite 13 of 27 of the staff already being minorities), the Democratic Congressional Campaign Committee this week fired six staffers, merely because they were white.

As the article at the link correctly notes,

This firing, and that’s what it is, not a free resignation, sends a message to everyone, and especially to young people of any race who are interested in politics. If an organization is actually willing to fire you from your job just because you’re white, do you really want to be involved with it?

Would you even want to vote for it?

The only criteria Democratic politicians use these days to determine their policy and opinions is skin color and ethnicity. Either you agree with them, or you are a racist.

For ordinary Democrats, this bigotry should cause great pause. Do you want to be associated with such bigotry?

LightSail-2 successfully raises its orbit using sunlight

Capitalism in space: By raising its orbit by the use of sunlight only, LightSail-2 has confirmed what an earlier Japanese solar sail Ikaros had demonstrated, that it is possible to use solar sails to travel in space.

Since unfurling the spacecraft’s silver solar sail last week, mission managers have been optimizing the way the spacecraft orients itself during solar sailing. After a few tweaks, LightSail 2 began raising its orbit around the Earth. In the past 4 days, the spacecraft has raised its orbital high point, or apogee, by about 2 kilometers. The perigee, or low point of its orbit, has dropped by a similar amount, which is consistent with pre-flight expectations for the effects of atmospheric drag on the spacecraft. The mission team has confirmed the apogee increase can only be attributed to solar sailing, meaning LightSail 2 has successfully completed its primary goal of demonstrating flight by light for CubeSats. [emphasis mine]

The highlighted text notes a secondary but possibly more important engineering achievement here. LightSail-2 was launched as a cubesat. It has now proven that such a cubesat can include a solar sail and use it for purposes of transportation.

Moreover, that this engineering test was funded entirely by private funds proves again that the government is not necessary for great things to be achieved.

They will continue to raise the spacecraft’s apogee for the next month, until the lowering of the perigee causes the spacecraft to get pulled out of orbit by the drag from the atmosphere. That second process will still take about a year.

More exoplanets found by TESS

Worlds without end: In confirming a candidate exoplanet previously discovered by TESS, astronomers have detected two more exoplanets orbiting the same star.

The transits TESS observed belong to GJ 357 b, a planet about 22% larger than Earth. It orbits 11 times closer to its star than Mercury does our Sun. This gives it an equilibrium temperature — calculated without accounting for the additional warming effects of a possible atmosphere — of around 490 degrees Fahrenheit (254 degrees Celsius). “We describe GJ 357 b as a ‘hot Earth,’” explains co-author Enric Pallé, an astrophysicist at the IAC and Luque’s doctoral supervisor. “Although it cannot host life, it is noteworthy as the third-nearest transiting exoplanet known to date and one of the best rocky planets we have for measuring the composition of any atmosphere it may possess.”

But while researchers were looking at ground-based data to confirm the existence of the hot Earth, they uncovered two additional worlds. The farthest-known planet, named GJ 357 d, is especially intriguing. “GJ 357 d is located within the outer edge of its star’s habitable zone, where it receives about the same amount of stellar energy from its star as Mars does from the Sun,” said co-author Diana Kossakowski at the Max Planck Institute for Astronomy in Heidelberg, Germany. “If the planet has a dense atmosphere, which will take future studies to determine, it could trap enough heat to warm the planet and allow liquid water on its surface.”

Without an atmosphere, it has an equilibrium temperature of -64 F (-53 C), which would make the planet seem more glacial than habitable. The planet weighs at least 6.1 times Earth’s mass, and orbits the star every 55.7 days at a range about 20% of Earth’s distance from the Sun. The planet’s size and composition are unknown, but a rocky world with this mass would range from about one to two times Earth’s size.

Even through TESS monitored the star for about a month, Luque’s team predicts any transit would have occurred outside the TESS observing window.

I think the results from TESS are soon going to overwhelm the general press. I myself had to check and make sure this story was about different exoplanets than the previous exoplanet discovery story from two days ago.

What is most interesting about these new exoplanets is their mass and size. TESS appears so far to be finding a lot of superEarths, something that Kepler did not do.

iSpace plans eight launches in 2020

After its first successful orbital mission last week, China’s semi-private rocket company iSpace announced today that it hopes to complete eight launches in 2020.

Clients from Singapore, Italy, Spain, Hong Kong and Sri Lanka, as well as mainland customers, have already either signed up for a spot on iSpace’s rockets or expressed interest.

iSpace is open to both private and government clients. “It’s the same for us whether it’s a private or a state-owned company,” Vice President for Marketing and Communications Yao Bowen said.

The price tag to launch a rocket is 4.5 million euros ($5 million), Yao added.

This launch price is just under what Rocket Lab has been charging, $6 million, and is clearly designed to take business from them. It is however higher than what Vector says it will charge, $4 million, should that company ever get its rocket off the ground.

The article also notes the investment capital raised by iSpace, totaling just over $100 million. This does make this company appear a private company, but don’t believe it. Its existence is very much tied to and supervised by the Chinese government.

Russia launches and docks new Progress freighter to ISS

Russia today launched and quickly docked a new Progress freighter, to ISS, with the trip taking slightly over three hours.

I think this might have been the fastest flight to ISS, though if not it is certainly among the fastest.

The leaders in the 2019 launch race:

11 China
11 Russia
9 SpaceX
5 Europe (Arianespace)
4 India

The U.S. continues to lead in the national rankings, 15-11.

Oberlin College posts $36 million bond, appeal to go forward

Oberlin College today posted a $36 million bond to cover the jury award to Gibson’s Bakery, thus allowing the college’s appeal of that verdict to go forward.

The judgement is now stayed about three weeks, until August 19, 2019, during which time Oberlin must submit its appeal. If it does so the stay will be extended another two weeks for responses, with a decision on September 9.

At that point expect further appeals, no matter how the judge rules.

Democrats once again push to repeal 1st amendment

A party of fascists: A group of Democratic Senators today re-introduced their 2014 constitutional amendment that would repeal the first amendment of the Bill of Rights.

The language from 2014:

To advance democratic self-government and political equality, and to protect the integrity of government and the electoral process, Congress and the States may regulate and set reasonable limits on the raising and spending of money by candidates and others to influence elections.

Essentially, this amendment eliminates the ban set by the first amendment that states that “Congress shall make no law … abridging the freedom of speech.”

If you have always been a registered Democratic, you need to reassess that position. This party has nothing to do with that political organization from the past. It has morphed into a fascist and oppressive bunch of totalitarians who pose a serious threat to everyone’s freedom.

School fires teacher for praising western civilization

They’re coming for you next: A California private school, covering elementary through high school grades and catering to Hollywood celebrities, fired one of its teachers in May for praising western civilization.

On the 5th of May, the American Freedom Alliance convened a conference on leftist radicalism. Before David Horowitz stepped up to the podium to discuss the threat of leftist extremism, Dr. Karen Siegemund, the president of the AFA, welcomed the attendees by speaking to our common values. “Each of us here believes in the unparalleled force for good that is Western Civilization, that is our heritage, whether we were born here or not,” she said.

After Dr. Siegemund and Horowitz’s remarks, a panel discussed radicalism in the school system.

The day after this event, Dr. Siegemund was informed by Le Lycée Français de Los Angeles, the school where she had taught mathematics for four years and where she had studied as a child, that her contract would not be renewed because she had praised western civilization.

The conference, which had addressed leftist radicalism in educational institutions, had struck home.

“On Monday, I was informed that my teaching contract won’t be renewed because of my ‘widely publicized views,’” Dr. Siegemund said. “You know, I’d always known I was vulnerable – of course. We on the right all know how vulnerable we are. But when it happens – when you actually become a victim, a casualty of this Long March, of the Left’s silencing tactics, it’s truly breathtaking.” [emphasis mine]

The key here is that the modern cultural left is not interested in other points of view. Either you agree with them, or you are evil and must be squashed. Or as Orwell said, speaking of the socialist/communist attitude toward power in 1984:

If you want a picture of the future, imagine a boot stamping on a human face — forever.

Orwell’s book was supposed to a warning to the future. Instead, for the left it has become an instruction manual. As spoken by those in power in Orwell’s book,

Don’t you see that the whole aim of Newspeak is to narrow the range of thought? In the end we shall make thoughtcrime literally impossible, because there will be no words in which to express it. Every concept that can ever be needed, will be expressed by exactly one word, with its meaning rigidly defined and all its subsidiary meanings rubbed out and forgotten…The process will still be continuing long after you and I are dead. Every year fewer and fewer words, and the range of consciousness always a little smaller.

The demonizing of western civilization and American history is all part of a comparable effort to make that knowledge inaccessible to future generations. And it appears that too many modern Americans are too cowardly to fight that effort.

A bullseye on Mars

Layered crater at equator
Click for full image.

Cool image time! In researching my piece last week on the glaciers of Mars I had wanted to include a picture of a typical concentric glacier-filled crater, the most widespread glacial feature on the Martian surface, found in a band at latitudes between 30 and 60 degrees. (You can see the example I found at the link above, near the end of the article.)

To find that picture I searched the Mars Reconnaissance Orbiter (MRO) archive. Among the images I found was a captioned image taken very early in MRO’s mission showing a crater with concentric rings very similar to the concentric glacial-filled craters. The image at the right is that crater, the image reduced and cropped to post here. As described in that caption,
