Ingenuity’s fourth flight today

9:05 am

The fourth flight of the Mars helicopter Ingenuity has just occurred, with data arriving momentarily.

The fourth Ingenuity flight from Wright Brothers Field, the name for the Martian airfield on which the flight took place, is scheduled to take off Thursday, April 29, at 10:12 a.m. EDT (7:12 a.m. PDT, 12:30 p.m. local Mars time), with the first data expected back at NASA’s Jet Propulsion Laboratory in Southern California at 1:21 p.m. EDT (10:21 a.m. PDT).

…Flight Four sets out to demonstrate the potential value of that aerial perspective. The flight test will begin with Ingenuity climbing to an altitude of 16 feet (5 meters) and then heading south, flying over rocks, sand ripples, and small impact craters for 276 feet (84 meters). As it flies, the rotorcraft will use its downward-looking navigation camera to collect images of the surface every 4 feet (1.2 meters) from that point until it travels a total of 436 feet (133 meters) downrange. Then, Ingenuity will go into a hover and take images with its color camera before heading back to Wright Brothers Field.

Stay tuned for new images. NASA will also hold a press conference tomorrow to outline the results and the rest of Ingenuity’s test program.

Arianespace’s Vega rocket launches six satellites

8:52 am

Arianespace yesterday successfully completed its first Vega rocket lift-off since a launch failure last year, placing six satellites in orbit.

This was Arianespace’s first launch in 2021. Though the year is still early, the timing of this launch, late April, puts them well behind the pace they have set for most of the 21st century.

The leader board for the 2021 launch race remains unchanged:

12 SpaceX
10 China
7 Russia
2 Rocket Lab

The U.S. still leads China 17 to 10 in the national rankings.

SpaceX launches 60 more Starlink satellites; China launches Tianhe station module

10:16 pm

Twas a busy evening. SpaceX successfully put 60 more Starlink satellites into orbit using its Falcon 9 rocket, with the first stage successfully completing its seventh flight, landing safely on the drone ship in the Atlantic.

China in turn successfully used its Long March 5B rocket to place in orbit the core module, dubbed Tianhe, of its planned space station. This is the first of eleven launches in the next two years to assemble the station’s initial configuration, including cargo and manned missions along the way.

The SpaceX live stream is at the link. I have embedded China’s English language live stream of the Tianhe launch below the fold. The launch is about 52 minutes in.

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.

Twisted taffy in the basement of Mars

Taffy on Mars
Click for full image.

Cool image time! The photo to the right, taken on March 7, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and cropped and reduced to post here, shows us an example of one of Mars’ strangest and most puzzling geological features, dubbed banded or “taffy-pull” terrain by scientists.

Taffy-pull terrain has so far only been found within Hellas Basin, Mars’ deepest impact basin and what I like to call the basement of Mars. Because of the lower crater count in this terrain scientists consider it relatively young, no more than 3 billion years old, according to this 2014 paper, which also notes

The apparent sensitivity to local topography and preference for concentrating in localized depressions is compatible with deformation as a viscous fluid.

At the moment what that viscous fluid was remains a matter of debate. Many theories propose that ice and water acting in conjunction with salt caused their formation, similar to salt domes seen on Earth. Other propose that the terrain formed from some kind of volcanic or impact melt process.

Almost all of the taffy terrain on Mars has been found in the deepest parts of Hellas Basin in a curved trough along its western interior, as shown by the light blue areas in the overview map below.

Today’s blacklisted American: Student is persecuted by university for asking a question

12:16 pm

Cancelled Bill of Rights
No longer exists at the University of Virginia

They’re coming for you next: Because medical student Kieran Bhattacharya dared to question the scientific validity of the term “microaggressions” during a panel discussion, the University of Virginia’s School of Medicine began an investigation that accused Bhattacharya of being a threat to others and banned him from the campus.

Here was what the student said.

“Thank you for your presentation,” said Bhattacharya, according to an audio recording of the event. “I had a few questions, just to clarify your definition of microaggressions. Is it a requirement, to be a victim of microaggression, that you are a member of a marginalized group?”

Adams replied that it wasn’t a requirement.

Bhattacharya suggested that this was contradictory, since a slide in her presentation had defined microaggressions as negative interactions with members of marginalized groups. Adams and Bhattacharya then clashed for a few minutes about how to define the term. It was a polite disagreement. Adams generally maintained that microaggression theory was a broad and important topic and that the slights caused real harm. Bhattacharya expressed a scientific skepticism that a microaggression could be distinguished from an unintentionally rude statement. His doubts were well-founded given that microaggression theory is not a particularly rigorous concept.

You can listen to the audio of this exchange here, beginning at about 28 minutes. Bhattacharya is respectful and calm, and is asking legitimate questions. It appears his main concern was the blanket vagueness of the term that allows anyone to claim a microaggression for almost any statement or act.

Apparently, the organizers of the event then decided that his questions were a microaggression in themselves, for which he must be punished.

Apollo 11 astronaut Michael Collins has passed away at 90

10:51 am

R.I.P. Michael Collins, the astronaut on Apollo 11 who stayed in lunar orbit while Neil Armstrong and Buzz Aldrin walked on the Moon, passed away today at the age of 90.

Collins was one of the most friendly and personable astronauts I ever met. He was always available and willing to answer questions, sometimes even willing to go an extra mile to provide you more than you asked for.

In many ways his later work as head of the Air & Space Museum was more important than his time as an astronaut. He helped make that museum and the history it documents one of the most popular in the world.

As long as humanity exists, on Earth and in space, Michael Collins will never be forgotten.

Perseverance as seen by Ingenuity

Perserverance as seen by Ingenuity
Click for full image.

Cool image time! JPL today released the photo to the right, cropped to post here. It was taken by the helicopter Ingenuity during its third flight on April 25th and shows the rover Perseverance at its left edge.

The horizon is tilted because the camera lens is very wide angle to capture as much terrain as possible and thus produces a fisheye curved distortion to the image’s periphery.

This image was taken as Ingenuity flew north about 160 feet away from Perseverance, probably in the first part of its flight as seen by photos taken by Perseverance of Ingenuity during its flight.

The mountains in the distance are the rim of Jezero Crater.

Dynetics has joined Blue Origin in protesting Starship contract by NASA

5:06 pm

Capitalism in space? Dynetics today joined Blue Origin in protesting NASA’s decision to award SpaceX the sole contract for building a manned lunar lander, using its Starship spacecraft.

Though the company’s protest did not going into specifics, it appears that Dynetics main complaint is the decision to not award two companies a contract, as originally planned. Even so, these factors make Dynetics bid quite problematic:

Of the three bidders, Dynetics was the lowest ranked. It had a technical rating of “Marginal,” one step below the “Acceptable” that Blue Origin and SpaceX received. Its Management rating of “Very Good” was the same as Blue Origin but one step below SpaceX’s “Outstanding.”

In the source selection statement, Kathy Lueders, NASA associate administrator for human exploration and operations, said the Dynetics lander “suffered from a number of serious drawbacks” that increased risk. The lander was overweight, which at this early stage of development “calls into question the feasibility of Dynetics’ mission architecture and its ability to successfully close its mission as proposed,” she wrote. The evaluation also questioned the maturity of the technology for performing in-space cryogenic fluid transfer required to refuel the lander, as the company planned.

Lueders concluded that “while Dynetics’ proposal does have some meritorious technical and management attributes, it is overall of limited merit and is only somewhat in alignment with the objectives as set forth in this solicitation.” The document only stated that Dynetics’ proposal had a price “significantly higher” than Blue Origin’s proposal, which in turn was significantly higher than SpaceX’s winning bid of $2.89 billion. Blue Origin disclosed in its protest that it bid $5.99 billion. [emphasis mine]

So, Dynetics proposed to build an overweight lander and do it at the highest price. If anything this protest enhances Blue Origin’s protest. It certainly doesn’t do much for Dynetics.

In fact, a good metaphor for the bidding here would be to imagine three vacuum cleaner salesman arriving at your door, all at the same time. One salesman, Mr. Newbie Dynetics, offers you a vacuum cleaner (as yet unbuilt in any form) that as presently designed will only be able to suck in about two-thirds of the dirt on your floor, and demands you pay $800 for it. The second salesman, Jeff “Blue” Origin, says his design (also unbuilt) is far better because they’ve done some successful tests of a tiny handheld prototype, and in addition he’ll only charge you $599 for it.

Neither Newbie or Jeff have any financing, so you will have to foot the entire bill.

The third salesman, Elon Starship, shows up with a full size prototype that while it has some problems, actually functions, and has been tested a number of times already. He also has more than two thirds of his development already financed by others, and only wants to charge you $289.

Who would you pick?

Since I know my readers are neither elected officials nor government officials in Washington and therefore know how to use their brains intelligently, I suspect I know.

We shall soon find out just how smart or dumb those elected officials or government officials in Washington really are.

Martian pit on top of Martian dome

12:55 pm

Dome with pit
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on March 7, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and was simply labeled “Pit on Top of Dome in Promethei Terra.”

The cropped section to the right shows one of two such pits visible on the entire image. Promethei Terra is a large 2,000 mile long cratered region due east from Hellas Basin, the deepest large region on Mars.

What caused these pits? The known facts provide clues, but do not really solve the mystery.

First, this image is located in the southern cratered highlands at 45 degrees south latitude. Thus, it is not surprising that it resembles similar terrain in the northern lowlands that suggests an ice layer very close to the surface.

Today’s blacklisted American: Any business in a Massachusetts town that does not genuflect to BLM and its Marxist agenda

11:31 am

Today's modern witch hunt
Witch burning returns to Massachusetts!

The worst horror of the new leftist blacklisting that is sweeping America is how pervasive it is. This intolerance for dissent is not limited to a small number of people leading the way, but seems to instead be springing upward from that movement’s grass roots.

Today’s blacklist story illustrates this quite starkly.

In the small town of Sturbridge, Mass., a group of 200 left-leaning citizens organized on Facebook to compile a list of businesses to avoid due to insufficient wokeness. The group even planned to present every local business with a pro-Black Lives Matter statement to sign — or face a local boycott.

When the website Turtleboy Sports published that list in full, the woman who created it, Sarah Prager, as well as the administrators of that private Facebook group, Amanda Ivey and Chelsea Ann, then apparently claimed (along with others from that group) that it was merely an internal document not meant for public viewing. They also justified its existence by saying it was not a blacklist but a list of all businesses in town, and had been designed merely to record the political leanings of each so that people would know which businesses had bad political leanings and could be properly avoided. Here are some examples, as noted by Turtleboy:

Starship prototype #15 completes static fire test

9:20 am

Capitalism in space: SpaceX’s fifteenth Starship prototype successfully completed a static fire test yesterday, and the company is now hoping to do its first test flight this week, possibly as early as tomorrow.

Meanwhile, preparations continue for the first test launch of a Superheavy prototype, as well construction at Boca Chica of the orbital launchpad.

The Orbital Launch Site is a hive of activity, with work ranging from the installation of large GSE (Ground Support Equipment) tanks to continued work on the launch mount and launch and integration tower.

The latter has now started to rise into the air next to the mount, which is yet to receive its launch table.

When finished, the tower will be the tallest structure in the region, at nearly 152 meters — towering over the 120 meter tall, fully integrated Starship/Super Heavy stack. The Tower will eventually host a crane and, as crazy as it initially sounded when Elon revealed it, arms designed to catch the returning booster.

It is not yet clear what the test schedule for Superheavy will be leading to that first orbital launch. They will likely fly a prototype on a hop first, then fly it with Starship stacked above. SpaceX however has not said exactly what its plans are, and even if it had, the company has been quite willing to revise those plans should it decide a change is advisable.

The commercial history of Russia’s Proton rocket

9:10 am

Doug Messier at Parabolic Arc today published a detailed launch history of Russia’s Proton rocket, outlining its commercial rise beginning in the 1990s and its fall in the 2010s with the arrival of SpaceX.

The fading of Proton reflected strong competition from SpaceX’s reusable Falcon 9 rocket, which captured an increasing percentage of commercial launches with significantly lower prices.

There was also a global shift away from Proton’s bread and butter, the geosynchronous communications satellite, toward large constellations deployed into low and medium Earth orbits.

Proton’s reputation was also damaged by serious quality control problems that affected the entire Russian launch industry. Proton suffered 9 launch failures and one partial failure in the 10 years between 2006 and 2015. The booster was left grounded for as long as a year at a time. Insurance rates for Proton flights soared.

Proton appears to still have six launches on its manifest, but the shift in Russia to its Angara rocket likely means the end of Proton’s long history, begun at the very beginnings of the space age in the 1960s, is in sight.

SpaceX leases bigger space at LA port for processing Falcon 9 boosters after launch

9:03 am

Capitalism in space: According to the mayor of Los Angeles, SpaceX has signed a new lease for more space at the city’s port, taking over the facilities no longer used by Sea Launch’s floating launch platform that is now in Russia.

News of the port lease broke on April 26th with a tweet from the mayor of Long Beach, California after the Port of Long Beach (POLB) Commission voted to approve SpaceX’s 24-month sublease with an effective start date of May 1st, 2021. From 2014 to 2020, a massive floating rocket launch complex and associated service ships once used by SeaLaunch called POLB’s Pier 16 home while mothballed and the company left behind a decent amount of infrastructure when it vacated the facility last year.

That includes a ~5600 square meter (~65,000 sq ft) warehouse and office space formerly used to process SeaLaunch payloads and Ukrainian Zenit rockets, as well as a pier and dock space generally optimized for loading and unloading large rockets from rocket transport ships. In other words, Pier 16 is a perfect fit for SpaceX’s needs.

SpaceX has twice before signed similar leases and then canceled them. Now it appears the deal is more firm, as the company appears to be gearing up for regular Starlink satellite launches from Vandenberg, requiring a bigger need in LA for processing Falcon 9 first stage boosters after launch.

I wonder too if this deal might be in connection with Starship and the two used floating oil rigs that SpaceX now owns and is refitting as Superheavy/Starship launch and landing pads. This LA facility would be ideal for these ocean platforms before and after launch.

German smallsat rocket startup wins launch contract

8:42 am

Capitalism in space: The German smallsat rocket startup company Isar Aerospace has won its first launch contract, to place an Airbus Earth observation satellite using its new Spectrum rocket.

Isar is one of three new German rocket companies competing for the smallsat market that all hope to launch for the first time next year.

Along with Rocket Factory Augsburg and HyImpulse Technologies, the three startups are competing as part of the German Space Agency DLR’s microlauncher competition.

The competition, which is being run in conjunction with ESA [European Space Agency], will award one of the three startups with 11 million euros ($13 million) in funding later this year. The funding is to be used to support a qualification flight that will carry a payload for a university or research institution for free. A second prize of 11 million euros in funding will then be awarded in 2022 as the final stage of the competition.

In evaluating the three startups, the DLR panel of judges will examine the technical aspects and commercial feasibility of each launcher. As a result, each startup’s success in securing funding and signing launch contracts will play a role in their chance of winning the competition.

Rocket Factory has also won a launch contract, with that commercial launch set for 2024.

Note how ESA is shifting its approach. Previously it focused its commercial effort entirely within the government-controlled Arianespace company. Now it is awarding competitive contracts to independent private companies. It appears that the ESA, like NASA, is adopting the recommendations put forth in my policy paper Capitalism in Space. It no longer wants to be the company but is instead acting as a customer looking for a product to buy.

Hopefully more than one of these three German companies will succeed, so that the competition will increase. That in turn will force prices down while encouraging greater innovation.

Blue Origin protests Starship contract award for lunar lander

10:09 pm

Blue Origin today filed a protest with the Government Accountability Office (GAO) of NASA’s decision to award SpaceX’s Starship the sole contract for building a manned lunar lander, claiming the agency “moved the goalposts” during the award process.

Blue Origin says in the GAO protest that its “National Team,” which included Draper, Lockheed Martin and Northrop Grumman, bid $5.99 billion for the HLS [Human Landing System] award, slightly more than double SpaceX’s bid. However, it argues that it was not given the opportunity to revise that bid when NASA concluded that the funding available would not allow it to select two bidders, as originally anticipated. NASA requested $3.3 billion for HLS in its fiscal year 2021 budget proposal but received only $850 million in an omnibus appropriations bill passed in December 2020. [emphasis mine]

The highlighted words kind of say it all. Blue Origin’s National Team put in a very high bid. Why should they have any expectation of winning?

Moreover, their track record, especially Blue Origin’s (the leader of the team), pales in comparison to SpaceX.

An evening pause: Seems appropriate with Ingenuity flying about on Mars. From the youtube webpage:

This was the maiden flight of my latest design. It was a bit of a mash-up, using existing wings and tail from old models. It weighs 1.5kg and was flying in about 7-10mph of wind. I feel it will be happier in about 5mph. The all-moving tail needs changing slightly as it developed some serious flutter if I picked up too much airspeed.

The uncertainty of science: A just-published survey of Mars following the 2018 global dust storm found that there was a significant increase in the seasonal dark streaks that scientists call recurring slope lineae, providing more evidence that these streaks are not caused by some form of water seepage but instead are related to some dry process.

The map to the right is figure 2 from that paper. The white dots show the candidate lineae that appeared following the 2018 global dust storm. About half were new streaks, not seen previously.

The devastating epidemic that simply wasn’t devastating

1:04 pm

It is now more than a year since the arrival of the coronavirus in the United States and the panicky wave of fear it brought to our governments and many of our citizens, shutting down whole states, bankrupting millions of businesses, and shuttering schools for practically a whole year. In the process our governments have demanded we change how we live in fundamental ways, from no longer gathering together in any social setting to wearing masks wherever we go, inside or out.

Was that reaction correct? Readers of my website know that I never believed it rational, and that it was an entirely out-of-proportion response to what was really nothing more than a new variation of the flu.

Well, we now have some data that reveals the actual scale of the COVID-19 epidemic, as shown by the CDC graph below:

Bill Nelson: now an advocate of private commercial space?

9:49 am

Though this is certainly not a firm rule, I rarely pay much attention to the nomination hearings in the Senate that take place whenever a new administration from another party takes over and nominates a new set of Washington apparatchiks to run various government agencies. Almost always, you can glean most of what you need to know by reading the nominee’s opening statement as well as later news reports. Saves a lot of time.

Last week came the nomination hearing of former senator Bill Nelson as NASA’s new administrator. As I had expected, based on all reports the hearing was a lovefest, with almost all questions friendly and enthusiastic. This is generally what happens when a Democrat gets nominated, as the Democrats have no reason to oppose the nominee and the Republicans generally don’t play “we oppose all Democrats, no matter what.” It also always happens when the nominee is a former member of that exclusive senatorial club, as Bill Nelson was.

The first news reports also mentioned that Nelson seemed surprisingly enthusiastic towards commercial space, given his past hostility towards it. This report by Mark Whittington today at The Hill provides a much deeper look, and notes that, as his report’s headline states, Nelson is now “a born-again” believer in the idea of capitalism in space, with NASA now merely being the customer. This is a major change from his position when he was a senator, when he tried repeatedly to strangle commercial space and give its money to SLS.

Nelson also announced that he was totally committed to continuing the Artemis program and timetable as laid out by the Trump administration:

Ingenuity completes third flight!

9:40 pm

Low resolution montage showing Ingenuity's third flight on Mars, April 25, 2021
Click for full resolution. Individual images can be found, in sequence, here, here, here, and here.

Early today Ingenuity successfully completed its third flight on Mars, traveling a considerable distance north from its taken-off point and then returning almost exactly to that point, as shown by the montage of four Perseverance navigation images above.

You will want to look at the high resolution montage, as the details are much clearer. The large mountains in the background are the rim of Jezero Crater. The smaller plateau in front of these mountains and much closer is the edge of the delta that Perseverance will explore.

According to this NASA press release:

The helicopter took off at 4:31 a.m. EDT (1:31 a.m. PDT), or 12:33 p.m. local Mars time, rising 16 feet (5 meters) – the same altitude as its second flight. Then it zipped downrange 164 feet (50 meters), just over half the length of a football field, reaching a top speed of 6.6 feet per second (2 meters per second).

I have embedded below the fold video of the helicopter’s take off, flight to the north, and then return and landing, created from Perseverance images. Because the camera did not pan the helicopter moves off frame for the middle part of its flight. In the coming days I expect they will assemble a video showing the entire flight.

The fourth flight is now only days away.

Soyuz-2 rocket launches 36 more OneWeb satellites

8:53 pm

Capitalism in space: Russia’s Soyuz-2 rocket today successfully launched from its Vostochny spaceport another 36 more OneWeb satellites, raising that internet constellation to 182 satellites of a planned 650 satellites.

The constellation will take 20 Soyuz launches to finish, and like other competitor services such as Starlink, is designed to provide high speed, low latency broadband services to areas where such service is unavailable now. Whereas Starlink is being marketed to individuals, OneWeb’s services are designed for enterprise customers, including broadband providers. User terminals can enable 3G, LTE, 5G, and Wi-Fi service over land, sea, and air.

The leaders in the 2021 launch race:

11 SpaceX
8 China
7 Russia
2 Rocket Lab

The U.S. still leads China 15 to 8 in the national rankings. And these numbers will likely see some change as there are four launches scheduled in the next four days. First ULA’s Delta 4 Heavy will launch a spy satellite tomorrow, then the next day Arianespace will do its first launch this year, launching a commercial Airbus Earth observation satellite with a Vega rocket.

On April 28 SpaceX plans to launch another 60 Starlink satellites, followed on April 29th by the launch by China of the first module of its space station, using their Long March 5B rocket.

Things are heating up, and this is only the beginning.

Curiosity’s mesa-top view of Gale Crater

The view of Gale Crater from on top of Mont Mercou
Click for full image.

Cool image time! The photo above, reduced slightly to post here, was taken on April 14, 2021 by one of the navigation cameras on Curiosity. The rover was then and is still sitting on top of the twenty foot high outcrop dubbed Mont Mercou.

Last week I had posted a panorama made from images at this viewpoint looking south towards Mount Sharp. Today’s image is from the same place, but now looks north across the floor of Gale Crater at the areas that Curiosity had previously traveled. I think the smallest mesas on the left of this image are the Murray Buttes which Curiosity was traveling through back in 2016, but am not certain.

The mountains in the far distance are the rim of the crater, about 30 miles away.

The new colonial movement: Yesterday China and Russia announced that they have signed an agreement to jointly work together to build a base on the Moon.

The link above is from the Chinese state-run press, stating:

In a joint statement issued at the conference, the CNSA and Roscosmos said the moon station will be open to all interested countries, international organizations and partners in terms of planning, design, research, development, implementation and operation at all stages and levels of the project.

The Russian state-run press made a similar announcement.

The new Cold War in space is beginning to shape up. On one side will be free enterprise, led by the United States and the many private companies working independently to make their own profits in space, and on the other side will be the former communist nations whose cultures require all such efforts be controlled from the top by the government.

And like the Cold War of the 20th century, the big question will be the actions of third parties, like Europe, India, Japan, the UAE, and other new space-faring nations. Will they join with the U.S., or join China and Russia to gang up on private enterprise? Right now I will not be surprised if all these countries eventually join the Chinese/Russian effort. Worse, I have great doubts about the U.S. government’s commitment to the capitalist path it is presently taking. If enough pressure was applied by these authoritarian regimes we should not be surprised if our generally authoritarian present government decides to join them as well, using their combined power to squelch freedom and private enterprise in space.

The battle is drawn, but the forces for liberty and freedom are sadly outnumbered.

China names its Mars rover Zhurong, after traditional fire god

9:52 am

The new colonial movement: The Chinese state-run press today announced that it has chosen Zhurong, a traditional Chinese fire god, as the name of the rover that is presently orbiting Mars on its Tianwen-1 orbiter and is targeting a landing sometime in mid-May.

They note that this name matches well with the Chinese name for Mars, “Huo Xing,” or fire star.

The announcement provided little additional information, other than stating that the prime landing site is in the previously announced Utopia Planitia region, which suggests the high resolutions images being taken by Tianwen-1 (unreleased by China) continue to show no reason to change that target.
