Today’s blacklisted conservative: Professor at Florida University to be fired for wrongthink
They’re coming for you next: A professor at the University of Central Florida, having taught there for 22-years with exemplary ratings, has now been under a seven-month-long investigation by the university, trying to drum up evidence that he created a “hostile” classroom environment so he can be fired, an investigation sparked by Black Lives Matter protests against him because he tweeted things that fascist movement doesn’t like.
The University of Central Florida is set to fire embattled Professor Charles Negy, accusing him of creating a “hostile” classroom environment, the Orlando Sentinel reported this week.
Negy became a target of intense Black Lives Matter protests over the summer after he tweeted: “Black privilege is real: Besides affirm. action, special scholarships and other set asides, being shielded from legitimate criticism is a privilege. But as a group, they’re missing out on much needed feedback.”
He has since deleted the tweet and a few others that caused controversy at the time, but a petition demanding he be fired had garnered nearly 35,000 signatures and protesters even targeted his home.
The university launched an investigation amid the turmoil and recently concluded Negy is guilty of classroom “misconduct,” the Sentinel reported, adding his termination will take effect Jan. 25.
I especially like the truly despicable manner in which the university gathered evidence against Negy:
A June 4th message posted to UCF’s website from the president, provost, and chief diversity officer addressed the content of Negy’s tweets directly and then stated: “If any student, current or former, believes they may have experienced abusive or discriminatory behavior by any faculty or staff member, we want to know about it. UCF takes every report seriously. Concerns can be reported to UCF’s IntegrityLine, which also takes anonymous complaints.” [Emphasis in original]
Read the whole thing. It is very clear that nothing Negy did in the past was considered misconduct, and in fact his work was rated excellent until this witch hunt, much of it inspired by anonymous slanders against him.
Moreover, reread his quoted tweet above. Nothing he says there is untrue. Nor is anything in it racist. It merely notes that affirmative action and being protected from criticism, as too many blacks today are merely because of their skin color, is not healthy for developing a critical mind. Such policies hurt minorities, not help them.
But then, having such opinions outside the norm of our leftist culture today is verboten, and will not be tolerated. And if you dare defy our political masters they will immediately gather to destroy you, no questions asked.
Negy is about to join the modern leftist blacklist, forbidden to speak and forbidden to work. I also think that if they could make him forbidden to even exist, they would. In fact, I fully expect this mob to go in that direction, given time.

The slowly disappearing dry ice cap at Mars’ south pole
Click for the 2020 full image.
Cool image time! The photo to the right of two images taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) was posted as a captioned image by the orbiter’s science team today.
This crater, dubbed the Happy Face Crater because of the shape of the blobby features within it, is located on the south pole ice cap of Mars, about 200 miles from the south pole itself.
Today’s caption noted how these pictures, taken nine years apart, illustrate the change going on at the Martian south pole.
The “blobby” features in the polar cap are due to the sun sublimating away the carbon dioxide into these round patterns. You can see how nine years of this thermal erosion have made the “mouth” of the face larger. The “nose” consisted of a two circular depressions in 2011, and in 2020, those two depressions have grown larger and merged.
While this caption noted the importance of studying these long term changes in order to understand the evolution of Mars’ climate and geology, it did not give the very specific discovery these changes suggest for Mars globally, a discovery that is actually very significant.
The two ice caps of Mars have some fundamental differences, all presently unexplained. The similarities are obvious. Both have permanent caps of water ice that are presently believed to be in a steady state, not shrinking or growing. Both each winter get covered by a thin mantle of dry ice that sublimates away completely with the coming of spring.
The differences are more puzzling, as shown by the maps of the two poles below.

Three aborted static fire tests yesterday for Starship prototype #9
Capitalism in space: After switching out three Raptor engines following successful static fire tests last week, SpaceX attempted three times to complete a new static fire test of Starship prototype #9 yesterday, only to have all three attempts abort just before ignition.
No word on the cause of the aborts, or what SpaceX’s next step will be. The article at the link speculates that SpaceX is merely being cautious, which doesn’t sound right to me. It could be there are specific issues with prototype #9 that are causing the problems. Remember, this is the prototype that tipped over in the assembly building and needed repairs.

Curiosity checks out its wheels
For full resolution images, go here and here for the
top image, and here and here for the bottom image.
Having finished a two week look at a sea of sand, Curiosity’ science team has resumed its journey east towards the higher slopes of Mount Sharp.
Before they started out however, they decided to aim the rover’s high resolution mast camera at Curiosity’s wheels to see how they are faring and whether any of the damage that occurred in the early days of the mission has worsened. The photo on the right compares what was seen this week with the damage on the same wheel as seen in July 2020. This is also the same wheel I have posted images of since September 2017.
Not only does there appear to be no appreciable new damage to this wheel in the six months since July, remarkably, a comparison between today’s image and the photo from September 2017, shows little change as well.
In the more than three years since that 2017 photo, Curiosity has crossed Vera Rubin Ridge, crossed the clay unit, climbed up the next ridge to take a look at the incredibly rough terrain of the Greenheugh Pedimont, and then continued across the clay unit on its way to higher and possibly more challenging terrain.
In all those travels it appears this particular wheel has fared rather nicely, accumulating in at least this part little new damage. This bodes well for the rover’s future, as the wheels have been a concern since Curiosity’s first two years on Mars, when engineers found they were experiencing more damage than expected. The travel techniques they have adopted since to protect the wheels appear to be working.

Today’s new blacklist member: Senator Josh Hawley
They’re coming for you next: Merely because conservative Senator Josh Hawley (R-Missouri) was disturbed by the many allegations of voter fraud and election tampering during the November 3rd election and wanted these allegations investigated before agreeing to the certification of a Joe Biden victory, he has become a marked man, with one publisher canceling a contract to publish his book, and the hotel chain Loews canceling a planned fundraising event for the senator.
Somehow, to the Loews corporate management, simply raising questions about voter fraud is now an act of violence and insurrection. From the Loews company:
We are horrified and opposed to the events at the Capitol and all who supported and incited the actions. In light of those events and for the safety of our guests and team members, we have informed the host of the Feb. fundraiser [for Hawley] that it will no longer be held at Loews Hotels.
Meanwhile, Simon & Schuster canceled Hawley’s book for similar absurd reasons.
As a publisher it will always be our mission to amplify a variety of voices and viewpoints: At the same time we take seriously our larger public responsibility as citizens, and cannot support Senator Hawley after his role in what became a dangerous threat.
That Hawley has for months consistently condemned all violence and rioting, this statement by Simon & Schuster reeks of crocodile tears, hypocrisy, and blatant partisanship. Trust me, as a modern publisher whose staff is dominated by young minds indoctrinated by leftist academia, Simon & Schuster has no interest in “amplifying a variety of voices and viewpoints.” Say something that criticizes the dominant leftist culture and they will squash you like a bug, instantly.
Welcome Senator Hawley to hallowed ground. You have now been blacklisted, merely because you have a different opinion than these liberal thugs. Hold your head high.

An empty Biden inauguration for a false victory
Photos from here.
For those who still think Joe Biden won his election legitimately and with popular support, you need only look at the two screen captures to the right, comparing the crowds at the previous presidential inauguration (at the top) and the crowd today at Biden’s inauguration.
It is also important to note that the Trump crowd in 2017 was totally normal, comparable to every past public inauguration since such events became occasions of grand splendor.
For Democrat Joe Biden, however, the lack of a crowd is essentially unprecedented. While past inaugurations were greeted with large enthusiastic crowds of citizens coming to celebrate the democratic and peaceful transition of power, today’s event was heralded by wartime security, barbed wire fences, military checkpoints, and a military police guard of 25,000 troops. Biden officials claimed this tight security was necessary because of the threat of violence.
I ask however: If 80 million voters swarmed the polls on November 3rd to elect Joe Biden, why does his new administration feel so afraid of the American people? No president in the past was this terrified of taking his oath of office in front of a gigantic crowd. Even Abraham Lincoln did so before a huge crowd in 1865, even as the Civil War still raged, as the photo below shows most emphatically.

Hints that NASA will redo the SLS static fire test
While NASA has not yet announced any decision on whether it will redo the full static fire test of its SLS core stage — following the January 16th abort — there are hints coming from industry sources that the agency is leaning to doing another test.
According to sources at the agency, program managers are in fact leaning toward conducting a second hot-fire test in Mississippi. Due to the need to obtain more propellant at the test site, conduct minor refurbishment to the vehicle, and possibly change the erratic sensor on Engine 4, the agency estimates it will require about three to four weeks before conducting another test.
Based on that schedule, the actual Artemis 1 unmanned flight, now set for November, will likely have to be delayed one month to December, since after the static fire test it will take several months to disassembly and prep the core stage for shipment to Florida and then reassembly it and prepare it for launch. That November launch date was predicated on a successful completion of the static fire test by January.
NASA and Boeing (the lead contractor building SLS) do not have much schedule margin however. They have begun stacking the solid rocket boosters that strap-on to the core stage. Once this is done the boosters supposedly have a life span of approximately one year, which means the launch must occur by about January ’22 though I would not be surprised if NASA waives that use-by-date if it needs to.
I am in a betting mood this morning. Want to bet SpaceX’s Starship completes its first orbital flight before SLS, even though it has been in development for one tenth the time (2 years vs 20) and for one thirtieth the cost ($2 billion vs $60)? I think the odds right now are very very likely. One way or the other, the race will definitely be neck-and-neck.

SpaceX buys two floating oil rigs for Starship/Super Heavy
Capitalism in space: As has been expected now since June, SpaceX has now officially purchased two floating oil rigs to be used for the launch and landing of its Starship/Super Heavy reusable heavy-lift rocket.
Named Phobos and Deimos, after the two moons of Mars, they are currently undergoing modifications to support Starship launch operations.
SpaceX has long been hinting at future floating launch and landing sites for their Starship launch system. The super heavy lift launch vehicle will have a large blast danger area and pose noise concerns if launched frequently near populated areas. Therefore, sea launch platforms will play a key role in the launch cadence SpaceX plans to reach with Starship, including on-orbit refueling flights for deep space missions and transportation from one place to another on Earth.
Job postings by SpaceX have indicated that work on offshore launch platforms has begun in Brownsville, Texas, near their Starship manufacturing and launch facilities in Boca Chica. Positions included crane operators, electricians, and offshore operations engineers, and several of the job listings specified that the position was part of the company’s Starship program. Job descriptions for these positions included responsibilities like “designing and building an operational offshore rocket launch facility” and required the “ability to work on an offshore platform in Brownsville, Texas.”
Out of work because you live in a fascist Democratic Party-controlled state and have had your job destroyed by their tyrannical policies? Move to Texas and go to work for SpaceX! At the moment at least the United States remains a collection of 50 sovereign states, with the ability of citizens to move from one to the other freely to improve their lives. Some states, such as Texas and Florida, are moving forward under the American concepts of freedom and private enterprise. Others, such as California and New York, are not.
Want to bet which ones will prosper in the coming decade? I pick Texas and Florida. Anyone willing to bet me?

Update on China’s pseudo-private commercial launch industry
Link here. Unlike past Space News articles which generally made believe these privately funded Chinese companies were truly private, the article at the link today is very clear about the close supervision maintained by the Chinese communist government over these companies. They might get funding through private investment capital, but everything they do is approved by their government.
A 2014 central government policy shift opened the Chinese launch and small satellite sectors to private capital. Since then around 20 launch vehicle-related firms have been established in China.
These commercial launch companies are being supported by a national strategy of civil-military fusion. This includes facilitating the transfer of restricted technologies to approved firms in order to promote innovation in dual-use technology. The State Administration for Science, Technology and Industry for National Defense (SASTIND) oversees activities.
Provincial and local governments are also providing support for space companies as they look to attract high-end and emerging technology firms.
The initial focus of the article is on iSpace, also called Interstellar Glory Space, which is planning another fund-raising round. This company, whose Hyperbola-1 solid rocket reached orbit for the first time in 2019, is now designing a liquid-fueled rocket whose first stage will be reusable.
The article also gives a quick review of some of the other Chinese companies.
It is all part of the new colonial movement, the international race to gain dominance in space. The competition is presently fierce, and should only become fiercer based on China’s decision to encourage internal competition.

SpaceX and Rocket Lab complete launches
Capitalism in space: Two successfully launches this morning.
First Rocket Lab used its Electron rocket to launch a German cubesat thought to be a prototype for a Chinese communications constellation, though no information has been publicly released. No recovery attempts were made on the rocket’s first stage.
Then SpaceX successfully completed its 17th Starlink launch and second launch in 2021. This puts about 950 Starlink satellites in orbit. The booster for this flight landed on the drone ship, completing its record eighth flight.
The 2021 launch race:
2 SpaceX
1 Virgin Orbit
1 China
1 Rocket Lab
The U.S. now leads China 4 to 1 in the national rankings.

SLS static fire abort not caused by malfunction but too-tight parameters
According to NASA today the reason the SLS static fire test cut off after only one minute was because of too conservative margins set in the computer software.
In an update today, however, NASA said it was engine 2 that caused the abort. At that moment, the engines were underdoing a gimble test where they are rotated in different directions just as they must do during ascent to steer the rocket. Actuators in the Thrust Vector Control system that generate the force to gimble an engine are powered by hydraulic Core Stage Auxiliary Power Units (CAPUs). The CAPUs for engine 2 exceeded pre-set test limits and the computer system automatically shut down the test as it was designed to do, but NASA said it would not have been a problem during a launch.
According to NASA’s update,
The specific logic that stopped the test is unique to the ground test when the core stage is mounted in the B-2 test stand at Stennis. If this scenario occurred during a flight, the rocket would have continued to fly using the remaining CAPUs to power the thrust vector control systems for the engines.
Note too that another issue during the test needs resolution:
Initial data indicate the sensor reading for a major component failure, or MCF, that occurred about 1.5 seconds after engine start was not related to the hot fire shutdown. It involved the loss of one leg of redundancy prior to T-0 in the instrumentation for Engine 4, also known as engine number E2060. Engine ignition begins 6 seconds prior to T-0, and they fire in sequence about 120 milliseconds apart. Test constraints for hot fire were set up to allow the test to proceed with this condition, because the engine control system still has sufficient redundancy to ensure safe engine operation during the test. The team plans to investigate and resolve the Engine 4 instrumentation issue before the next use of the core stage.
No decision has been made yet whether they will do another static fire test before shipping the core stage to Florida for launch. They are under a time limit, as they have begun stacking the SLS rocket’s strap-on solid rocket side boosters, and those only have a life expectancy of one year once stacking has begun.
As far as I am concerned, nothing about the development of this rocket makes sense. I would never fly on it no matter how much money was offered to me, and anyone who does must know the terrible risk they take.

They are under a time limit, as they have begun stacking the SLS rocket’s strap-on solid rocket side boosters, and those only have a life expectancy of one year once stacking has begun.
As far as I am concerned, nothing about the development of this rocket makes sense. I would never fly on it no matter how much money was offered to me, and anyone who does must know the terrible risk they take.
New daily record for search engine DuckDuckGo
DuckDuckGo, the search engine that respects the privacy of its users, has set a new record for use with more than a 100 million daily search requests for the first time.
Privacy-focused search engine DuckDuckGo reached a major milestone in its 12-year-old history this week when it recorded on Monday its first-ever day with more than 100 million user search queries.
The achievement comes after a period of sustained growth the company has been seeing for the past two years, and especially since August 2020, when the search engine began seeing more than 2 billion search queries a month on a regular basis. The numbers are small in comparison to Google’s 5 billion daily search queries but it’s a positive sign that users are looking for alternatives.
The numbers are still too small. Why is anyone who reads this still using Google? It is incredibly trivial to switch. More important, you will find that you are getting better information in your searches, as DuckDuckGo does not play favorites nor does it squelch results from some websites because it disagrees with their politics.
And best of all, your privacy will be better protected.

Today’s blacklisted conservative: Lawyer who represented Trump fired by university
They’re coming for you next: A lawyer who both represented Trump in his legal challenges to the November 3rd vote count as well as gave a public speech in support of Trump has been fired by his university.
Chapman University President Daniele Struppa promptly denounced Eastman for engaging in constitutionally protected free speech. Struppa accused Eastman in a Jan. 8 statement of playing “a role in the tragic events in Washington, D.C., that jeopardized our democracy. … Eastman’s actions are in direct opposition to the values and beliefs of our institution. He has now put Chapman in the position of being publicly disparaged for the actions of a single faculty member, and for what many call my failure to punish and fire him,” Struppa wrote.
Struppa also said, “This week has also demonstrated that this country has a great deal of work to do for social justice and equity.”
Lisa Leitz, a professor of peace studies at Chapman, was one of 169 faculty members who signed an open letter addressed to the university demanding Eastman be fired. She told a local media outlet that Eastman’s appearance at the rally and his Trump campaign activities have damaged the university. “It associates us with a racist insurrection against the U.S. democracy, and it undermines the credibility of every faculty member,” she said.
On Jan. 13, Struppa announced that a settlement had been reached with Eastman and that he would be leaving his post “effective immediately.”
And what exactly did this man do? Nothing illegal, that’s for sure. All he did was express his opinion, in public, and then take action as a lawyer to represent his client.
I plan on posting one of these “newly blacklisted” stories daily for as long as they keep happening. Sadly, I already have a backlog. I could be reporting these stories of oppression and blacklisting I think for the next four years, daily, without any trouble at all. That is assuming of course they don’t come after me and get this website shut down, something I fully expect is a possibility in the next four years.
And remember, these attacks against outspoken conservatives are only a precursor for when these thugs come after you, no matter who you are. You might not be speaking out publicly, but you have had the temerity to read this material, something that the cultural dictators who now rule us cannot allow.

More evidence Mars’s glaciers formed across many ice ages
The uncertainty of science: New research using the boulders found on the top of Martian glaciers has now strengthened the evidence that Mars must have undergone many previous ice age cycles going back as much as 800 million years, with those glaciers waxing and waning during each cycle.
This new data helps map the cycles earlier than 20 million years ago, which have been difficult to map out based solely on the orbital data available from Earth and from Mars orbit. The results suggest that before then there were from six to twenty additional cycles during the last 300 to 800 million years.
These numbers are decidedly uncertain. It is likely that there were many more cycles, as suggested by the many layers seen at the edges of the north and south polar ice caps.
Be aware as well that if you read the press release you should know that it falsely implies that this research is the first to map out these ice age cycles. This is not true. All this research has done is provide more evidence for cycles prior to 20 million years ago, cycles that scientists have long believed must have happened based on other data.
In the end, for us to map out the full climate history of Mars will require numerous ice core samples at the planet’s poles, something that will not be possible until people are living and working on Mars routinely.

Mysterious colors on Mars, near the landing site of Europe’s rover
Click for full image.
Cool image time! Today the science team for the high resolution camera on Mars Reconnaissance Orbiter (MRO) released a new captioned image, which I have cropped and reduced to post here to the right.
The photo was taken October 12, 2020, and shows a small very colorful area on top of an isolated hill. To quote the caption, written by Sharon Wilson:
An isolated, elongated mound (about 1 mile wide and 3.75 miles long) rises above the smooth, surrounding plains. Horizontal layers are exposed at the northern end of the mound, and its surface is characterized by a very unusual quasi-circular pattern with varying colors that likely reflect diverse mineral compositions.
…The origin of this mound is unknown, but its formation may be related to the clay-bearing rocks in the nearby Oxia Planum region.

Chang’e-5’s lunar samples less dense than expected
Because the lunar samples retrieved by China’s Chang’e-5 probe were less dense than expected, it ended up recovering only 3.8 pounds of material rather than the targeted 4.4 pounds.
The probe had estimated the lunar rocks to have a density of 1.6 grams per cubic millimetre, based on data from past missions by other countries, said Pei Zhaoyu, the mission spokesman. Going by that figure, the probe stopped taking samples after just 12 hours, apparently assessing that the target had been reached. “However, from tests, the actual density might not be that high,” Pei told reporters.
This is not a failure, but a discovery. In order to make sure the lander did not recover too much material, weighing too much, they needed to set limits based on the expected weight of the material recovered. That these samples taken from the Mons Rümker volcano complex are lighter than expected reveals something about them. It suggests the lava here was different than lava samples taken elsewhere.

Beals Science – Resurrecting a carbide lamp
An evening pause: Long time cavers are very familiar with the carbide lamp, as it was used routinely until around 1998, when LED lights arrived and finally superseded it.
Until then, the advantage of a carbide light was the quality of the light it produced, a soft bright glow rather than the harsh reflective rings produced by older electric lights.
The disadvantage however was the endless fiddling required to keep them working. For example, near the end of this video when he finally gets the light to work, he turns up the water flow to brighten the light. I guarantee that very soon the light would go out, as he was flooding the carbide. The water drip had to be precisely right. Too slow and not enough gas. Too fast and too much water.
I personally hated carbide lights because of that fiddling, especially because lamps made after 1970 were junk and didn’t work well. Most cavers who used carbide would scour yard sales to find old lights like this one, as older carbide lamps were made well and would work reliably.

Today’s new member of the blacklist: conservative radio host Robert Pratt
Without warning the marketing heads of the corporation that manages the radio stations that air the conservative Pratt on Texas radio show for the past fifteen years announced today they were cancelling the program, despite its profitable status and high ratings.
Robert Pratt’s comments on this decision:
Since I began the program, in April of 2006 taking the time slot of the syndicated Michael Reagan show, Pratt on Texas has more than paid the show’s way increasing TM’s take during the time slot significantly. It was setup that way with Clear Channel in 2006; if successful it was to be a complete win-win proposition and if not it would fold.
And thanks to each of you, I had it confirmed Friday night, that ratings for Pratt on Texas are as great as ever. We have consistently been not just the top talk or news program in our base KFYO market in “afternoon drive,” we have generally been the top, second, or third spot with our intended adult demographic, in all radio formats, in each ratings book for 14 years – almost unheard of. But those things are not valued in Cancel Culture because the goal is to have fewer hear differences of opinion, not more.
Despite what one TM employee has intimated this weekend to a former TM employ, there has been no contractual or other dispute between TM and Perstruo Texas, Inc. (Perstruo Texas, Inc. is the entity that owns and contracted with TM to provide Pratt on Texas and of which I am an employee and officer.)
So no, there is no money losing, no sagging ratings, nor business disputes (other than the cancellation executed Friday night of course.)
Understand that Cancel Culture doesn’t care about money. Cancel Culture is about advancing a political agenda and operates outside of the idea of making money and being successful financially. The goal is to marginalize, at minimum, and to de-platform and destroy the ability of opposing viewpoints from reaching an audience.
Post election certification, Cancel Culture has rapidly grown beyond its roots in social media to include all forms of media and political thought sharing. It will flourish without mass opposition.
I have no doubt this is the reason behind this decision as well, based on numerous discussions I’ve had with other conservative media people. They are scared, they have ample evidence that the fascist left is coming for them, and they don’t know what to do about it.

Pioneers and the future
From Pioneer: The asteroid mining ship Dream Watcher docked
on the Mars space station Landville, c2183.
When I first wrote my sole science fiction book, Pioneer, back in the mid-1980s, I strongly believed (and still do) that for the human race to prosper in space and truly build new civilizations on other worlds, freedom, private enterprise, and courage would be required.
It was for this reason there is absolute no mention of NASA in the book. Unlike most modern movies that idolize this mostly dysfunctional government agency and see it as the only solution for accomplishing anything in space (watch The Martian again to see what I mean), I knew that while government will be strongly involved in space exploration for the foreseeable future, for anything to get done quickly those governments will best step aside and figure out how to let their citizens both freely do it and also own what they do.
This weekend’s aborted SLS static fire test illustrates my point perfectly. Rather than depend on private enterprise to get this rocket built, both George Bush Jr. and Congress decided to give the job to their government bureaucrats. The result has been nothing for now over a decade.

Where I was this past weekend
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
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.

SLS core stage static fire test aborts after only one minute
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.
