Partly engulfed Martian craters
Click for full image.
Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) on October 31, 2020. It shows a crater that appears buried in a sea of material so that pretty much the only thing visible is top of its rim.
The full image shows a second larger crater to the northwest that looks the same. In both cases the material fills the craters also fills the surrounding terrain.
Yet, both craters appear to be surrounded by a faint skirt of uplifted material.
What caused this situation?

We are about to find out who our real friends are
Russian Sergei Krikalev on the space shuttle, February 1994.
When in 2002 I was writing my space history, Leaving Earth, I spent more than a month interviewing Russian astronauts in Moscow. Many of those individuals had also flown on the American space shuttle during the initial Mir-Shuttle joint missions followed by the start of the assembly of ISS, which had given them a unique opportunity to get an outsider’s perspective on American culture.
One man Sergei Krikalov, was especially unique. He not only was the first Russian to train at the Johnson Space Center in Houston, he was the first Russian to fly on the space shuttle, and the first to enter ISS’s first module after launch. Because of that experience, he also spoke excellent English, which meant he could describe his experiences to me directly, and not through an interpreter.
When it came to American culture, he noted how as a Russian, he was appalled at the empty nature of American friendships.

Congress frees Europa Clipper from SLS
It appears that Congress has at last removed its requirement that the unmanned probe Europa Clipper must be launched on the continually delayed and very expensive SLS rocket.
Almost unnoticed, tucked into the 2021 fiscal NASA funding section of the recently passed omnibus spending bill, is a provision that would seem to liberate the upcoming Europa Clipper mission from the Space Launch System (SLS).
According to Space News, the mandate that the Europa Clipper mission be launched on an SLS remains in place only if the behind-schedule and overpriced heavy lift rocket is available and if concerns about hardware compatibility between the probe and the launcher are resolved. Otherwise, NASA is free to search for commercial alternatives to get the Europa Clipper to Jupiter’s ice-shrouded moon.
Not only will this secure Europa Clipper’s launch schedule, which had deadlines imposed by orbital mechanics that SLS was not going to meet, the more than $1 billion in savings by using a SpaceX Falcon Heavy will allow the probe to do more while giving NASA more money for other planetary missions.
This is excellent news. It signals that Congress’s long love affair with SLS because of the ample pork it sends to many districts might finally be waning. If so, there is a good chance it will finally be killed, freeing up its bloated budget.
Sadly, in a sane world some of those savings would be used to reduce the overall federal deficit even as some was also used to expand NASA’s space effort. We are not in a sane world, however, so expect no reduction in the federal budget, at all.
Still, this is a move by Congress towards some fiscal responsibility that will make NASA’s efforts more efficient. For that small improvement we should be grateful.
Another new rocket startup, ABL Space, to launch its rocket in ’21
Capitalism in space: ABL Space, another one of the many startups attempting to enter the launch market using private investment capital, now predicts it will attempt its first orbital launch sometime before June of this year.
The company was formed by veterans of SpaceX and Wall Street, and uses that company’s philosophy of building as much of the rocket in-house as possible. That rocket is also more powerful than Rocket Lab’s, aiming for bigger payloads, and is designed with a very simple launchpad arrangement, so that it can launch from practically anywhere there is a concrete pad and do it quickly.
ABL now has about 105 employees, with about 90,000 square feet of space in several buildings in El Segundo, as well as testing facilities at Edwards Air Force Base and at Spaceport America in New Mexico. “We can build and ship a launch vehicle about every 30 days, based on infrastructure we have now,” Piemont said. “We’re tracking towards eight or nine [rockets] a year based on existing infrastructure.”
While ABL has significant contracts and relationships with the Pentagon, Piemont said the company’s customer pipeline is 60% private, or commercial, versus 40% government payloads. The company has customers lined up to launch payloads on its first few missions, although ABL may fly mass simulators, which are often a slab of concrete to represent a spacecraft’s weight, for the first RS1 launch.
By my count, this makes seven new rocket companies — Virgin Orbit, Firefly, Astra, Relativity Space, Aevum, ABL Space, and Blue Origin — all planning their inaugural launches in ’21. The competition for business thus should be very fierce, which is all to the good, as it will encourage these companies to all find ways to cut costs.
The new dark age of silencing
Click for most recent page.
The dark age has arrived! The screen capture on the right, cropped, rearranged, and color adjusted slightly to fit here, comes from the front page of the conservative news aggregate site Rantingly from tonight, the evening of January 8, 2021, only two days after Congress certified Joe Biden as president-elect and only three days after the Democrats had confirmed that they will have majority control of the both the House and Senate in Congress.
I have highlighted in red the pertinent stories. Very quickly, the Democratic Party’s allies in at Google, Twitter, Facebook, and Apple have moved to shut down many legitimate and popular conservative and Republican news outlets, including the Twitter feed of the President of the United States. With the Democrats in control of the government, these leftist internet platforms know they have nothing to fear by doing this, that if anything the Democrats controlling Congress will applaud them and encourage them to censor more conservative and Republican outlets, to shut them all down if possible.
Beforehand, these social media platforms had held their fire somewhat out of fear that the Republicans would change their special tax status exemptions that define them as open platforms, not publishers. No longer. Their desire to silence their opponents can now swing into high gear, and they are pushing it for all it is worth, including attempting to silence their direct competitors, such as Parler, a twitter-like platform that prides itself on censoring no one.
It is also very important to recognize that this isn’t being done only by the big corporate bosses. No, sirree, this censorship of conservatives and Republicans is fully endorsed by the workforce at these companies. Today’s young generation, properly indoctrinated in leftist-controlled universities to hate conservatives and view them all as white supremacists, have been eager to do this for the last two years, and have actually been held back by their corporate bosses. The reins are now off, and their modern culture of oppression and intolerance has moved to the forefront. Persecution is now cool!
This is only the beginning. Even as I wrote this post more links appeared at Rantingly of more examples of censorship.
For myself, because I for years refused to do business with corrupt companies like Google, Apple, Facebook, and Twitter, there is not much they can do right now to hurt me. But these actions today point to the future, and I am not confident my immunity will last very long. The leftists doing this have the power and the willing support of a large percentage of the population. They will use that power and support to jam their boot into every one of their opponent’s faces, given time.
The worst part of this horror is that the people who should read it and learn from it, the low information Democratic Party supporters who really don’t understand how evil that party has become, will never see it. My readers generally agree with me. Those that do not generally fall into two categories, those who are strongly partisan and will deny these facts whole-heartedly, or hacks working for the Democratic Party who come here merely to spread misinformation and lies.
The decent and moderate people who are knee-jerk Democrats and who desperately need to read this and to see the intolerance spreading across America from the party they support are just not interested. They will turn away, dismissing what I write with a wave of the hand. This can’t be true! It must be some mad conspiracy claims of the racist alt-right! And maybe those sites are bad and should be silenced!
And I write this from direct knowledge. I have been surrounded by these people my entire life, being a secular Jew who has also been a college teacher, a film maker, and a science journalist. All these communities are dominated by low information Democrats. I have known them all and have I spent my life trying to get them to wake up, all to no avail.
They will not see. They will not hear. And they will not speak up. And so, worse is coming. We no longer live in the land of the free and the home of the brave.
Soon, it will be a land of oppression and murder and genocide, all because too many Americans decided to close their minds and do nothing.

Colliding galaxies!
Click here and here to see full images.
Cool images from Hubble! The two photos to the right, cropped and reduced to post here, shows two different galaxies undergoing a collision with another galaxy. Both images are from of a montage of six galaxy merger images from the Hubble Space Telescope, released yesterday.
To celebrate a new year, the NASA/ESA Hubble Space Telescope has published a montage of six beautiful galaxy mergers. Each of these merging systems was studied as part of the recent HiPEEC survey to investigate the rate of new star formation within such systems. These interactions are a key aspect of galaxy evolution and are among the most spectacular events in the lifetime of a galaxy.
It is during rare merging events that galaxies undergo dramatic changes in their appearance and in their stellar content. These systems are excellent laboratories to trace the formation of star clusters under extreme physical conditions.
The first galaxy merger to the right is dubbed NGC 6052, and is located in the constellation of Hercules about 230 million light-years away. This pair of colliding galaxies, according to the caption, “were first discovered in 1784 by William Herschel and were originally classified as a single irregular galaxy because of their odd shape. However, we now know that NGC 6052 actually consists of two galaxies that are in the process of colliding.”
The second image shows two galaxies, IC 694 and NGC 3690, about 700 millions after they had completed a close pass of each other. From the caption: “As a result of this interaction, the system underwent a fierce burst of star formation. In the last fifteen years or so six supernovae have popped off in the outer reaches of the galaxy, making this system a distinguished supernova factory.”
You can see all six merger images here, though to my eye these two are the most impressive.
Draping moraines on Mars
Click for full image.
Cool image time! The photo on the right, rotated, cropped, reduced, and annotated to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter on October 6, 2020. It shows the northern interior rim of 42-mile-wide Greg Crater in the southern cratered highlands of Mars.
What makes it interesting is the curving ridge that appears to drape itself around several larger hilltops. That ridge is a moraine, the debris or glacial till that accumulates at the foot of glaciers as push their way down hill. As the glacier had flowed those hills became obstacles, so that the glacier (and its moraine) were forced to go around.
The overview map and wider view from the context camera on MRO below give the setting.

Momentus forced to delay its first mission due to FAA bureaucrats
Capitalism in space? Momentus, aiming to provide satellite makers a tug that can move satellites to their preferred orbit, has delayed its first mission because the many bureaucrats in the federal government need more time to review the paperwork.
In a Jan. 4 statement, Momentus said the flight of its first Vigoride tug, which was to be part of the payloads on a Falcon 9 dedicated rideshare mission launching as soon as Jan. 14, will be delayed to later in the year because it was unable to get approval from the Federal Aviation Administration for the mission. “This move will allow for the additional time necessary to secure FAA approval of Momentus’ payloads, including completion of a standard interagency review,” the company said in a statement.
The company did not elaborate on that review, but part of the FAA commercial launch licensing process is a review of the payload that the agency describes as intended “to determine whether its launch would jeopardize public health and safety, safety of property, U.S. national security or foreign policy interests, or international obligations of the United States.” That process can include consultation with other government agencies.
In a Jan. 5 document filed with the Securities and Exchange Commission in the form of an interview, Fred Kennedy, president of Momentus, said there was no specific issue that was delaying that review. “The FAA did not express any specific concerns of its own, but rather indicated that more time was needed to complete its interagency review of Momentus’ payload,” he said. [emphasis mine]
The highlighted words reveal the truth. There is nothing wrong with the payload or its tasks. The problem is that several government agencies have not completed the paperwork, and so Momentus must wait. I imagine that there is a thick application sitting on some bureaucrat’s desk, requiring a signature, and that bureaucrat has been too busy collecting his or her paycheck at home because God forbid he or she might get the cororavirus by coming into work.
This is modern America. You don’t have the real freedom to do what you want. You must sit, twiddling your thumbs, while your betters in Washington decide whether they will allow you to do it. It doesn’t matter they know little or nothing about your goals. All that matters is that they are in charge, and can boss you around at their whim.

SpaceX launches Turkish communication satellite
SpaceX today successfully completed the first launch of 2021, placing a communications satellite built by Airbus for Turkey.
The first stage successfully completed its fourth flight. Both fairings were also used, having flown previously.
At the moment, SpaceX is the only one to launch in 2021, so it leads the world at the moment.
