Where I was this past weekend

11:15 am

Bob Zimmerman underground

Several readers have asked in the comments for a report on what I did this past weekend.

I went caving. The photo to the right, taken on a previous trip several years ago, will give you an idea. The cave is amazingly beautiful. The trip was to designed to give a bunch of people a chance to see it.

I won’t say much more than this, mostly because it is unwise to reveal too much about the caves one visits because this then attracts people to them who are often either inexperienced (and thus a risk to themselves) or untrustworthy in terms of protecting the cave’s beauty. I am totally willing and open to bring anyone who wants to go to the caves I visit, but a newbie should go the first time with someone experienced, for the reasons already outlined.

Virgin Orbit’s LauncherOne successfully reaches orbit

9:35 am

Capitalism in space: After eight years of development, Virgin Orbit has finally used its LauncherOne air-launched rocket to successfully put ten satellites into orbit.

After an eight month stand down to resolve issues revealed during the first mission of Virgin Orbit’s LauncherOne rocket, the company made their second orbital launch attempt on Sunday, January 17. The air-launched rocket successfully carried ten CubeSats to their target orbit for NASA’s Educational Launch of Nanosatellites (ELaNa) program.

This makes Virgin Orbit the second smallsat rocket company to achieve orbit, following Rocket Lab. They have beat out a large number of startups, and are now well positioned to gain some of the market share in this new component of the launch market.

They have also made true my September 2016 prediction that Virgin Orbit would complete its first commercial launch before Virgin Galactic’s first suborbital commercial flight, even though Virgin Galactic’s SpaceShipTwo began development eight years earlier.

As for the 2021 launch race, right now only SpaceX and Virgin Orbit have launched in 2021. They are tied for the lead, and also combine to put the U.S. ahead 2 to nothing over everyone else.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

The print edition can be purchased at Amazon or any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

SLS core stage static fire test aborts after only one minute

9:23 pm

During the crucial first static fire test of SLS’s core stage yesterday — meant to last a full eight minutes — the booster aborted the test after only one minute.

It’s still too early to know exactly what caused the early shutdown in Saturday’s engine test.

Flight controllers could be heard during the test referring to an “MCF” (a major component failure) apparently related to engine No. 4 on the SLS booster. John Honeycutt, NASA’s SLS program manager, added that at about the 60-second mark, cameras caught a flash in a protective thermal blanket on the engine, though its cause and significance remain to be determined.

Honeycutt said it’s too early to know if a second hot-fire test will be required at Stennis, or if it can be done later at NASA’s Kennedy Space Center in Florida, where the SLS is scheduled to launch the uncrewed Artemis 1 mission around the moon by the end of this year. Similarly, it’s too early to know if Artemis 1 will still be able to launch this year. “I think it’s still too early to tell,” Bridenstine said of whether a 2021 launch for Artemis 1 is still in the cards. “As we figure out what went wrong, we’re going to know kind of what the future holds.” [emphasis mine]

If this engine abort had occurred during a launch, with the two strap-on solid rocket boosters still firing (and no way to turn them off), the entire rocket would have been lost. Thus, for NASA to even consider shipping this core stage to Florida before figuring out the problem and fixing it is downright insane.

They need to figure out what went wrong, fix it, and then test again, even if if means the first unmanned Artemis flight experiences a serious delay. If they don’t then this whole program is proved to be an idiotic sham (something I have believed for about a decade), and should be shut down by Congress and the new President, immediately.

I am reporting this late because this weekend I was out in the country on a caving trip, taking a very much needed break from the truly horrible news of modern America.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

SpaceX replacing two engines on Starship prototype #9

1:11 pm

Capitalism in space: After the static fire engine tests earlier this week, SpaceX has decided to replace two of the Raptor engines in its ninth Starship prototype before moving on to its 50,000 foot test flight.

“Two of the engines need slight repairs, so will be switched out,” SpaceX founder and CEO Elon Musk said via Twitter early this morning (Jan. 15).

Musk did not give a target launch date for SN9. But he did say, in another tweet, that it’s “probably wise” to perform another static fire with the vehicle after the engine swap is complete. So a weekend launch for SN9 seems pretty unlikely.

Makes sense, but I must admit a bit of disappointment. I was really hoping that the next flight would occur on the same day NASA attempts its first static fire test of the core stage of SLS. The contrast would have been edifying.

Personally this delay is great for me, as I will be out in the country caving this entire weekend, and would have missed it if it had occurred during the weekend. I will miss the SLS static fire test, but that will be far less interesting (unless something goes wrong).

Blue Origin aims for first manned suborbital flight in April

8:41 am

Capitalism in space: According to this CNBC report, Blue Origin is now targeting its first manned suborbital flight of New Shepard by April, after completing one more unmanned test flight in late February.

Blue Origin on Thursday completed the fourteenth test flight of its New Shepard rocket booster and capsule. Called NS-14, the successful test flight featured the debut of a new booster and an upgraded capsule. Beyond the upgrades, CNBC has learned that NS-14 also marked one of the last remaining steps before Blue Origin flies its first crew to space.

The flight was the first of two “stable configuration” test flights, people familiar with Blue Origin’s plans told CNBC. Stable configuration means that the company plans to avoid making major changes between this flight and the next. Additionally, those people said that Blue Origin aims to launch the second test flight within six weeks, or by late February, and the first crewed flight six weeks after that, or by early April.

We shall see. The sources are anonymous, and thus not entirely reliable. Furthermore, this schedule is far faster than the pace that Blue Origin has traditionally set.

At the same time, the competition to get those first suborbital passengers in space is heating up, as Virgin Galactic is rumored to have a somewhat similar schedule. Moreover, the first entirely private manned orbital tourist mission by SpaceX is presently set for October. If these two suborbital companies fail to begin manned flights before SpaceX their ability to garner customers will be sorely damaged.

InSight scientists give up on heat sensor mole

9:25 pm

After another failed attempt earlier this month to dig with the German-made mole on the InSight Mars lander, the science team has decided to abandon all further efforts.

After getting the top of the mole about 2 or 3 centimetres under the surface, the team tried one last time to use a scoop on InSight’s robotic arm to scrape soil onto the probe and tamp it down to provide added friction. After the probe conducted 500 additional hammer strokes on 9 January, with no progress, the team called an end to their efforts.

This means the heat sensor, one of the two instruments carried by InSight, is also a failure, and will not be able to provide any data about the planet’s interior temperature.

From the beginning InSight appears to have been a poorly run and badly chosen project. Other than a weather station, it carried only two instruments, a seismometer and a heat sensor. Its launch was delayed two years when the French attempt to build the seismometer failed and JPL had to take over, fortunately with success. Now the failure of the German-made mole has made the heat sensor a failure.

To send a lander to Mars at a cost of a billion dollars with so little payoff seems in hindsight to have been bad use of money. Plenty of other NASA planetary missions have done far better for far less.

Another professor arrested for hiding ties to China

9:11 pm

An MIT professor has been arrested for hiding his extensive ties to the Chinese communist government, even as he took almost $20 million in grants from the Department of Energy.

According to prosecutors, Gang Chen, a mechanical engineering professor at MIT, has held various positions on behalf of the PRC aimed at promoting China’s technological and scientific capabilities. He allegedly shared his expertise directly with Chinese government officials, “often in exchange for financial compensation,” said prosecutors in the U.S. attorney’s office in Boston.

The Chinese consulate in New York allegedly requested that Chen, a naturalized U.S. citizen, act as an “overseas expert” for the PRC. He was also a member of two talent programs that the PRC has used to place Chinese students at American universities.

This is not the NASA scientist who pled guilty to similar charges yesterday.

It appears to me that the Trump Justice Department is trying to wrap up as many of its cases of academics spying for China as it can before Joe Biden takes over.

Leftist activist arrested for inciting riot at Capitol

9:03 pm

A leftist activist who is very anti-Trump and heads an organization founded in support of Black Lives Matter causes has been arrested by the FBI for participating and inciting the riot that occurred at the Capitol Building on January 6th.

[John] Sullivan, the founder of “an activist group formed after the killing of George Floyd in the summer of 2020” entitled Insurgence USA which “calls itself anti-fascist and protests police brutality,” insisted he was only inside the U.S. Capitol on January 6th to “record.”

…The 18-page affidavit reveals that Sullivan allegedly incited violence by exclaiming “we gotta get this [expletive] burned” and “it’s our house mother[expletive].” … During one of his interactions with others, Sullivan can be heard in the video saying, “We gotta get this [expletive] burned.” At other times as he is walking through the Capitol, Sullivan can be heard saying, among other things, “it’s our house mother[expletive]” and “we are getting this [expletive].”

At this link you can see a video of Sullivan speaking at what appears to be a DC rally, threatening violence and insurrection against Trump.

He is not the only one arrested, and his leftist agenda only illustrates that the politics of the individuals who attacked the Capitol Building were not all the same. It also adds weight to the possibility that many who were there were not there in support of Trump, as has now become the accepted but very unproven wisdom, but might actually have been there to help slander those Trump supporters.

And I still want to know more about that woman in the pink hat.

Craters in slush on Mars

Dust devil steak across a slushy plain on Mars
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on October 27, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It was taken not for any particular research project, but as one of the periodic images the camera team needs to take maintain the camera’s proper temperature. When they need to do this, they often will take a picture in an area not previously viewed at high resolution. Sometimes the image is boring. Sometimes they photograph some geology that is really fascinating, and begs for some young scientist to devote some effort to studying it.

In this case the photo was of the generally featureless northern lowland plains. What the image shows us is a scattering of impact craters that appear to have cut into a flat plain likely saturated with ice very close to the surface.

How can I conclude so confidently that these craters impacted into ice close to the surface? The location gives it away.

These rioters in the Capitol are not Trump protesters

11:39 am

Below is a video taken inside the Capitol building on January 6th, apparently right after protesters have broken a window and gotten inside. It opens with one of them asking someone outside “Where’s the floor plan?” Later a woman in a pink wool hat outside sticks her head through the window, shouting military-like commands with a bullhorn.

Watch. I have been to numerous conservative demonstrations. I have never ever seen Republican protesters act like this. Never. Their behavior has almost always tried to stay within the law, and when someone begins to act unlawfully, usually there are cries everywhere to stop, with several quickly moving in to prevent it. Conservative protesters also are never organized in this manner. They come to the protest randomly, and mill about randomly.

A second video at this link is from outside before they have broken the window, and shows the woman in the pink hat apparently in command and helping to use a battering ram, clearly prepared beforehand, to smash a window.

As far as I am concerned, these rioters are not supporters of Trump. Their techniques, behavior, and approach all scream Antifa, in every way, dressed up to look like Trump supporters.

I might be wrong. There is no evidence right now one way or the other. Finding and interrogating that woman in the pink hat would be especially illuminating, because this footage clearly shows her breaking the law and leading the attack.

Too bad we no longer have a legitimate police force in DC willing to honestly investigate this.

Scientist pleads guilty of lying about ties to China

8:50 am

A NASA scientist yesterday pled guilty of lying about his participation in China’s Thousand Talents program, designed to recruit scholars for stealing U.S. intellectual property.

On or about October 27, 2020, MEYYAPPAN was interviewed by the FBI, NASA OIG, and the USAO, in New York, New York. During that interview, MEYYAPPAN falsely stated, among other things, that he was not a member of the Thousand Talents Program and that he did not hold a professorship at a Chinese university. In truth and in fact, MEYYAPPAN was a member of the Thousand Talents Program and held a professorship at a Chinese university, funded by the Chinese government.

This guy is one of a slew of scientists the Trump administration has caught spying for China. There are certainly many others, as our academic community generally has more loyalty to communism and China than it does to the U.S.

Unfortunately, he will likely be one of the last such spies caught, as we can surely expect the Biden administration, with its own ties to China, to shut down this national security work.

Blacklists are back and the Democrats have got ’em

9:50 pm

The Bill of Rights, cancelled

They’re coming for you next: Oh boy, it’s the 1950s again and its time for witchhunts from Congress and big corporations.

Unlike the 1950s, however, the question will not be whether you have ever been a member of the Communist Party. No, now the question will be much more effective and to the point. It will be “Have you ever been conservative or a member of the Republican Party?”

And as always, today’s progressive Democratic Party is on the ball! Congresswoman Alexandria Ocasio-Cortez has revealed members of the House are planning to form a commission to “rein in” conservative media, to prevent them from “spewing disinformation and misinformation.”

During a lengthy Instagram Live on Tuesday evening where she revealed that she feared for her life during the siege, the “Squad” member accused the mainstream media of “spewing disinformation” ahead of the deadly riot in which five people died.

“There’s absolutely a commission that’s being discussed but it seems to be more investigating in style rather than truth and reconciliation,” she said. “I do think that several members of Congress in some of my discussions have brought up media literacy because that is part of what happened here,” Ocasio-Cortez (D-NY) went on. “We’re going to have to figure out how we rein in our media environment so you can’t just spew disinformation and misinformation,” she said.

Hey, Alexandria, I’ve got the perfect name for your congressional commission. Why not call it the House Un-American Activities Committee? You could subpoena right-wing writers and journalists to testify against their will in Congress, demanding to know their party affiliations. You could also set up lists of these proven conservatives so that businesses nationwide can blacklist them and keep them from working.

In fact, many of big corporations, their boards dominated by Democrats, are already ahead of the curve, cutting off all donations to all Republicans who simply wanted to find out if there was election fraud in the 2020 election. Other businesses in turn have begun firing anyone who worked for Trump.

It is obvious, Alexandra, that the work will be rewarding and productive. Get that committee going. Send out those subpoenas. Harass those witnesses.

We can’t have those evil Republicans poisoning our glorious socialist paradise, can we?

Starship prototype #9 completes three static fire tests in one day

3:36 pm

Capitalism in space: SpaceX engineers today successfully completed three static fire tests of their Starship prototype #9, all within a space of just over three hours.

The three-engine SN9 vehicle performed its second, third and fourth “static fire” tests in quick succession today (Jan. 13) at SpaceX’s South Texas facilities, near the Gulf Coast village of Boca Chica. The engines lit up briefly at 1:28 p.m. EST (1828 GMT), again at 3:22 p.m. EST (2022 GMT) and then yet again at 4:36 p.m. EST (2136 GMT).

During static fires, engines blaze briefly while a vehicle remains tethered to the ground. SN9 already had one such test under its belt, having completed a short static fire on Jan. 6.

In each case they likely practiced their countdown and fueling procedures, followed by procedures allowing for a quick recycle should they have to abort a countdown but have time to still launch that day.

All this strengthens the reliability and overall design and operation of the rocket as they develop it.

The actual hop could occur, based on road closure announcements, on Friday. It is also possible the company will do additional static fire tests beforehand.

I think it also pertinent to once again compare SpaceX’s development approach to that of Boeing and NASA in their development of SLS. SpaceX is aggressively doing a lot of tests of hardware, continually. They then redesign and rebuild based on those tests. The pace is fast and compressed, and gets things built at a remarkable low cost, considering. It also forces them to design things in a way that makes redesign easy and fast.

Boeing and NASA have done no such tests in building SLS. Instead, they designed it by computer, giving themselves large safety margins in design. This might have reduced or eliminated the need for tests, but it raises the cost of the rocket while stretching out the development time enormously. And it carries great risk. In two days they will attempt their very first static fire test of SLS’s core stage, after almost a decade of development. The actual launch is planned for within a year.

If that static fire test has any issues, the whole SLS project will face serious problems that will, based on its design, be very difficult to fix.

Perseverance's landing ellipse on Mars
Click for full image.

In just over a month, on February 18, 2021, the American rover Perseverance will come screaming through the thin atmosphere of Mars at a speed of over 12,000 miles per hour to hopefully land successfully in Jezero Crater.

The map to the right, cropped and reduced to post here, was released last week by the Perseverance science team and shows the landing ellipse in that crater. It also shows the much larger landing ellipses of previous landers/rovers. As they noted,
