Update on MOXIE’s two years on Mars, producing oxygen

9:17 pm

Link here. MOXIE is a technology test instrument on the rover Perseverance that has proven it will be possible to practically produce sufficient oxygen from the Martian atmosphere to sustain a human colony.

The link provides a nice summary of everything the engineering team has accomplished since Perseverance landed in testing this technology. As I wrote in my December post about MOXIE’s achievements:

Based on these tests, MOXIE has unequivocally proven that future human explorers will not need to bring much oxygen with them, and will in fact have essentially an unlimited supply, on hand from the red planet itself. More important, MOXIE has also proven that the technology to obtain this oxygen already exists.

All we need to do is plant enough MOXIE trees on Mars.

Midnight repost: The Democratic Party of thugs and goons

1:01 am

The indictment of Donald Trump this week on bogus charges by a local New York Democratic Party machine politician, done for entirely political reasons, once again illustrates the ugliness of that party. Seems therefore appropriate to repost this August 2022 essay. The only thing that has changed since then an increase in the aggressive, vicious, and violent nature of the Democrats and their allies in the various LBGQTBIBOC etc queer and bigoted identity movements. They are acting with ever greater impunity, while we certainly have not seen any clear evidence that the decent population of the United States has risen up in outrage. Instead, it increasingly appears they are bowing their heads in fear, and letting the bullies win.

It also appears that even if decent Americans finally now step up with outrage, it will be too little too late. For far too long they slept, and now they reap the whirlwind.

The Democratic Party of thugs and goons

Rick, stating the truth in Casablanca
Will the Trump raid finally wake Americans up?

While the outrage and fury has only begun to rise over the unjustified raid of the home of former President Donald Trump yesterday by the FBI, ordered by Biden Justice Department with a warrant issued by an Obama-supporting judge with ties to Jeffrey Epstein’s child sex operation, nothing about that raid was anything new or startling. For the past seven years, since Donald Trump won the presidency in 2016, the Democratic Party and its supporters have increasingly acted like Nazi storm-troopers, willing, able, and eager to crush their opponents at every opportunity, and to do so cruelly and with great viciousness.

I therefore ask, shouldn’t we have exhibited the same amount of rage and fury for the hundreds and hundreds of ordinary Americans these same thugs have harassed and ruined since 2016? Why did it take a raid on Trump to finally bring that rage to the forefront?

Two Americans committed suicide because of Biden administration persecution after they dared protest the questionable election of Joe Biden on January 6th. What about them?

Scores of conservative FBI agents in the past two years have been fired from their jobs, simply because they did not agree politically with the Democrats. What about them?

What about the arrest by the FBI of a Republican candidate for Michigan governor, simply because he had also protested on January 6th the questionable election of thug Joe Biden? Or the threats of violence and murder against Supreme Court justices by leftist Democratic Party allies?

What about the effort by Biden’s labor board to shut down the conservative outlet The Federalist, simply because its founder sent out an anti-union joke?

What about the former Trump lawyer whose career was destroyed, simply because he was a former lawyer of Trump?

These stories are only a small sampling of the political abuses of power exercised by Democrats and the Biden administration time after time against their political opponents in just the last eighteen months. The list is long and painful to read.

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, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, 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

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.

Sponge terrain on Mars

Sponge terrain on Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on January 11, 2023 by the high resolution camera on Mars Reconnaissnace Orbiter (MRO).

The scientists labeled this picture “Rocky Terrain.” Though this describes the overall sense of the full image, it fails to capture correctly the nature of this patch of ground at the center of the picture. As you can see, this patch of spongelike surface starts and ends abruptly. It appears that it is a layer on top of the surrounding terrain that has also been eroded aggressively since its placement.

The many craters on its surface seem to have come later, though as the crater size diminishes it becomes harder to separate the craters from the sponge holes. Moreover, some of the larger craters are distorted in shape, as if the impact hit material that was viscous and could flow somewhat.

The overview map below gives some context, but only some.

Spain’s government officially establishes a Spanish space agency

9:41 am

Spain’s Council of Ministers has voted to officially established a Spanish space agency, with operations beginning on March 7, 2023 with an initial budget of $753 million.

This announcement comes only a month before the private Spanish company, PLD, attempts its first suborbital launch from a Spanish spaceport of its Miura-1 rocket, its first stage designed to come back to Earth by parachute, recovered, and then reused. If successful the company hopes to then develop an orbital version.

The news from Europe increasing suggests that the members of the European Space Agency (ESA) are beginning to go their own way, relying less upon it. In addition to these developments in Spain, Germany now has three private companies developing rockets while Italy’s government has provided $308 million to its own Italian rocket company Avio. The United Kingdom meanwhile has had its own space agency for several years, is building several spaceports, and has been trying to develop its own space industry, with very mixed results. In addition, both Norway and Sweden are building spaceports for commercial operations.

ESA, while mouthing support for commercial space, has so far not done well in the past decade in transitioning from a government run, built, and owned operation to one owned by commercial companies. Its new Ariane-6 rocket, built and controlled by ArianeGroup but heavily managed by ESA, is still too expensive to compete with the new commercial rockets from the U.S. Nor does it appear ESA is moving very fast to fix this situation. It appears many people in Europe have recognized this state of affairs, and are looking for alternatives.

Two launches by China

9:15 am

China's spaceports
China’s spaceports

China yesterday and today successfully completed two launches using two different rockets from two different spaceports.

First, a Long March 2D rocket yesterday launched a set of four satellites establishing a new constellation of radar satellites designed to measure the Earth’s surface topography. Lift off was from the Taiyuan Satellite Launch Center in the northeast of China. No word on where the rocket’s first stage crashed.

Next, a Long March 4C rocket today placed in orbit a classified military “remote-sensing” satellite, lifting off from the Jiuquan Satellite Launch Center in China’s northwest. Once again, no information was released on where the first and second stages of the rocket crashed to Earth.

The leaders in the 2023 launch race:

21 SpaceX
13 China
6 Russia
3 Rocket Lab

American private enterprise still leads China 24 to 13 in the national rankings, and the entire world combined 24 to 23. SpaceX now trails the entire world combined, including American companies, 26 to 21.

Virgin Orbit shuts down

5:12 pm

Unable to secure new funding, the managers of Virgin Orbit have shuttered the company, possibly forever.

Virgin Orbit is ceasing operations “for the foreseeable future” after failing to secure a funding lifeline, CEO Dan Hart told employees during an all-hands meeting Thursday afternoon. The company will lay off nearly all of its workforce. “Unfortunately, we’ve not been able to secure the funding to provide a clear path for this company,” Hart said, according to audio of the 5 p.m. ET meeting obtained by CNBC.

The layoffs include all but 100 positions, about 85% of its workforce.

The company was killed because the UK’s Civil Aviation Authority (CAA) took an extra six months approving a launch license, during which the company could launch nothing and thus make no money. Lacking revenue, it ran out of cash. If the company goes into bankruptcy, this detail is most intriguing:

Branson has first priority over Virgin Orbit’s assets, as the company raised $60 million in debt from the investment arm of Virgin Group.

In other words, Branson will be able to walk off with everything, and even resurrect the company as his own, for pennies on the dollar. If he does, I guarantee our bankrupt mainstream press will shower him with praise, calling him a hero.

A bubbly cauldron on the surface of Mars

A bubbly cauldron on the surface of Mars
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on December 20, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a strange terrain of craters and mounds, with all the mounds having pits within them like volcanic calderas. In between the surface has a two-toned stippled look, as if two different materials are in the process of mixing.

My immediate impression was that of the bubbly surface of a vat of tomato sauce simmering. Or maybe the vile mixture created by the witches in Shakespeare’s Macbeth, which as they mix they chant:

First witch:
Round about the cauldron go;
In the poison’d entrails throw.
Toad, that under cold stone
Days and nights has thirty-one
Swelter’d venom sleeping got,
Boil thou first i’ the charmed pot.

ALL:
Double, double toil and trouble;
Fire burn, and cauldron bubble.

Of course, this is not a vat of witch’s brew or tomato sauce. It is the surface of the planet Mars, but an alien surface nonetheless.

Frank Rubio’s flight to ISS will exceed a year, setting a new American record

10:25 am

Frank Rubio
Frank Rubio

Initially, Frank Rubio’s first flight in space was intended to be a standard six month mission on ISS. Launched on September 21, 2022 on a Soyuz-2 rocket inside a Soyuz capsule, the plan was for him and his two crewmates to return in March, 2023.

Then their Soyuz capsule developed a leak in its coolant system in December 2022. Not knowing if it was safe to use this capsule with humans inside, a replacement unmanned Soyuz capsule was launched by the Russians to ISS in February 2023, with the leaking Soyuz capsule brought back unmanned earlier this week.

The Russians however decided that this new capsule, designed for a six month mission, would stay in orbit for six months, so that it would be used to its planned capability. This decision also hinged on the lack of a new crew arriving on this new capsule. If it brought Rubio and his crew home earlier, ISS would be short three crew members for at least several months.

The planned return date, September 27, 2023, now means that Rubio’s mission will be at least 371 days long, making him the first American to fly a full year in space. Previously NASA falsely touted Scott Kelly’s 340-day mission as a year-long mission, when it never was. Later, Mark Vande Hei’s mission, also launched on a Soyuz, was extended to 355 days, still just short of a year, because the Russians wanted to send a film crew to ISS and return them on the capsule which Vande Hei was intended to come home on.

Whether Rubio truly does spend a year in space however remains uncertain. Two different Russian spacecraft — the Soyuz and a Progress freighter — have developed this coolant leak in the past three months. If this problem is a systemic manufacturing error, which Russia is now investigating, the decision might be to return the new capsule sooner than planned, out of fear it will develop its own leak. We shall likely find out sometime in the next three months.

If Rubio does end up in space for a full year, however, it will likely be a dream come true, having become an astronaut in 2017 but waiting six years for his first flight.

New startup unveils 3D printer for making rocket tanks and fairings

10:02 am

Rosotics, a new startup focusing on providing manufacturing components for rocket companies, has now unveiled a prototype of its proposed 3D printer, dubbed Mantis, for making rocket tanks and fairings.

Mesa, Arizona-based Rosotics plans to begin delivering the Mantis in the third quarter of 2023 to customers who place $95,000 deposits and sign hardware-as-a-service contracts. After delivery, Rosotics “will install, maintain and upgrade your hardware over time without any cost to you,” LaRosa said.

While the Mantis can be configured for various tasks, the starting point is a one printhead to additively manufacture aluminum or steel structures ranging in size from 1.5 to 8 meters in diameter.

The idea is sell this manufacturing capability to rocket companies as well as other manufacturers who need large structures built. Rather than machining these large structures themselves, or have outside machining companies do it for them, the companies would buy Mantis to do it in-house instead.

Whether this model will work depends on price and operations. Is it cheaper and quicker to use this 3D printer to make large rocket parts, or traditional methods? Obviously, Rosotics thinks it is. We will find out if others think so if Rosotics survives.

H3 failure delays Japan’s entire space program

9:53 am

According to one official of Japan’s space agency JAXA, the failure of the first launch of its new H3 rocket in early March now threatens the schedule of much of Japan’s entire space program, even those missions being launched on the older H2A rocket.

The investigation into the launch failure, when the upper stage of the H3 rocket failed to ignite, remains unfinished with no word when it will be completed.

The H3 upper stage uses an engine designated LE-5B-3 developed by MHI [Mitsubishi Heavy Industries] and similar to the LE-5B engine used on the existing H-2A rocket. That is putting launches of the H-2A on hold while the investigation continues.

That may delay the upcoming launch of two science missions sharing an H-2A. The X-Ray Imaging and Spectroscopy Mission (XRISM), an X-ray astronomy spacecraft, and the Smart Lander for Investigating Moon (SLIM), a lunar lander, were scheduled to launch together as soon as May on an H-2A.

The article notes that XRISM replaces a 2016 Japanese X-ray telescope that failed immediately after launch. That failure then was bad, but just as bad is the seven years it has taken JAXA to have a replacement ready.

The H3 failure also threatens a JAXA Mars mission scheduled for launch in 2024, during the next launch window to Mars.

Japan’s space program more and more resembles Russia’s. It is controlled entirely by the government, which it appears does not allow competition within Japan, as all major rocket work is apparently confined to Mitsubishi. There have been unending quality control problems, within many probes as well as in the development of both the H3 and the Epsilon rockets. And the pace of operations is slow, much slower than other nations or companies.

It seems a major reform is needed, and it should start with Japanese government officials reading Capitalism in Space. They need to open up competition and release their space program from the control of JAXA, especially because JAXA is not doing a very good job. Like NASA, it would be better if JAXA stopped being a designer and builder, and become merely a customer obtaining products from many different competing private companies.

Russia’s Soyuz-2 rocket launches classified military satellite

11:06 pm

Russia today successfully launched a classified military satellite, using its Soyuz-2 rocket lifting off from Plesetsk spaceport in northern Russia.

The rocket traveled north over the Arctic Ocean, so its first stage fell harmlessly into the ocean.

The leaders in the 2023 launch race:

21 SpaceX
11 China
6 Russia
3 Rocket Lab

American private enterprise still leads China 24 to 11 in the national rankings, and the entire world combined 24 to 21. SpaceX now trails the rest of the world, including other American companies, 21 to 24.

In U.S. sales of dumb phones are up

4:00 pm

It appears that American users of mobile phones are shifting every so slightly away from smart phones, with sales of simple flip-phones lacking a screen rising in the past year.

In the U.S., feature flip phone sales were up in 2022 for HMD Global, with tens of thousands sold each month. At the same time, HMD’s global feature phone sales were down, according to the company.

In 2022, almost 80% of feature phone sales in 2022 came from the Middle East, Africa and India, according to Counterpoint Research. But some see that number shifting, as a contingency of young people in the U.S. revert back to dumb or minimalist phones. “In North America, the market for dumb phones is pretty much flatlined,” said Moorhead. “But I could see it getting up to 5% increase in the next five years if nothing else, based on the public health concerns that are out there.”

Companies like Punkt and Light are catering to the trend, selling devices geared toward those with a desire to spend less time on their phones and social media. On YouTube, you will find a slew of influencers touting these phones.

It is not clear if this is a real trend, or merely a bit of press release salesmanship by HMD and others. If it is however I think it is a good trend. Smart phones do very little to make people smarter. Instead, they foster a shallow thinking process focused on emotion. The more people who get away from them the better.

Psyche asteroid mission now scheduled for October 2023 launch

3:40 pm

After a year delay because certain flight software was not ready on time for its first launch window in the fall of 2022, the science team for the Psyche asteroid mission are now aiming for an October 2023 launch.

The launch period will open Oct. 5 and close Oct. 25. The asteroid, which lies in the outer portion of the main asteroid belt between Mars and Jupiter, may be the remains of a core of a planetesimal, a building block of a rocky planet.

Due to the new launch date, Psyche has a new mission plan, which includes a flyby of Mars for a gravity assist and arrival at the asteroid in August 2029. The mission then will enter its 26-month science phase, collecting observations and data as the spacecraft orbits the asteroid at different altitudes.

Meanwhile, the two Janus probes that were to launch with Psyche last year remain in limbo, as this new Psyche launch date is useless to that mission’s plan to fly past a different asteroid.

Boeing & NASA; 1st Starliner manned mission to now launch on July 21

3:34 pm

In a update posted by NASA today, agency and Boeing officials announced that they are now aiming to launch Boeing’s Starliner capsule on July 21, 2023 on its first manned mission to ISS.

The new target date provides NASA and Boeing the necessary time to complete subsystem verification testing and close out test flight certification products and aligns with the space station manifest and range launch opportunities.

The specifics behind this somewhat meaningless press release jargon can be found at this twitter thread. Apparently Boeing & NASA want to do more ground tests of the capsule’s parachute system as well as its flight software. There also appears to be some issue relating to the capsule’s batteries.

Boeing is also mulling a redesign of Starliner’s batteries for after this delayed crewed flight test. It also expects to redesign Starliner’s smart initiator system, which separates the crew from service module. NASA’s paying $24 million for that redesign amid added requirements

Though Boeing has a fixed price contract with NASA, if NASA demands redesigns or changes it has to pay for them. That Boeing and NASA are finding these issues at this late date, four years after Starliner was first supposed to launch, does not speak well of Boeing’s workmanship and quality control systems.

The chaos between galaxies following their head-on collision

2:09 pm

The chaos between galaxies following their head-on collision
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken using the Gemini North ground-based 8-meter telescope in Hawaii. It shows two spiral galaxies about 180 million light years away following a head-on collision about 25 million years ago, in which the smaller spiral moved through the larger from the bottom to the top.

Upon exiting, the smaller spiral trailed behind it the reddish stream of material, while its outside arms on the right were bent downward. That trailing material is why astronomers have dubbed these the “Taffy Galaxies.” Imagine pulling two clumps of taffy apart. The stretched material linking the two clumps is the bridge of trailing material between these two galaxies. From the caption:

When the Taffy Galaxies’ collided, their galactic disks and gaseous components smashed right into each other. This resulted in a massive injection of energy into the gas, causing it to become highly turbulent. As the pair emerged from their collision, high-velocity gas was pulled from each galaxy, creating a massive gas bridge between them. The turbulence of the stellar material throughout the bridge is now prohibiting the collection and compression of gas that are required to form new stars.

The evolution of galaxies is incredibly slow, from the perspective of human existence. For example, this first collision 25 million years ago seems like it took a long time, but it will likely be followed by many more over the next billion years, eventually resulting in a single spherical elliptical galaxy. On the time scale of the universe, collisions every 100 million years or so means galaxies like this can mix and collide many times, and do so well within the existence of the theorized lifespan of the universe itself.

To us short-lived humans, however, this process just seems so slow it can’t possibly happen as described. But it does.

Sidebar: It appears this image was released to herald the repair of Gemini North’s primary mirror, which was damaged in two places on its edge during a recoating operation on October 20, 2022. Since then the telescope has been shut down as repair operations were undertaken. That repair is now complete, and it is expected the telescope will resume science observations in a few weeks.

SpaceX launches another 56 Starlink satellites

1:19 pm

SpaceX today successfully launched another 56 Starlink satellites, using its Falcon 9 rocket lifting off from Cape Canaveral, Florida.

The first stage successfully completed its fourth flight, landing on a drone ship in the Atlantic.

Russia was also launching at almost the exact same time a classified military satellite, using its Soyuz-2 rocket lifting off from Plesetsk spaceport in northern Russia, but at the moment there is no word on whether that launch was a success.

For the moment then the leaders in the 2023 launch race are as follows:

21 SpaceX
11 China
5 Russia (with a planned launch today)
3 Rocket Lab

American private enterprise now leads China 24 to 11 in the national rankings, and the entire world combined 24 to 20. SpaceX now trails the rest of the world, including other American companies, 21 to 23.

Zhurong: Small polygons on light curved dunes indicate regular atmospheric water interaction

1:12 pm

Zhurong's full journey on Mars

A paper published this week in Geophysical Research Letters by the science team for China Zhurong Martian rover has revealed the discovery of small polygon cracks on the surface of the many curved light-colored small dunes found in the region where Zhurong landed, suggesting the possibility of relatively recent water activity between the atmosphere and the dune surfaces.

Those dunes, dubbed transverse aeolian ridges (TARs) by the science team, are the many light curves visible in the labeled Mars Reconnaissance mosaic to the right. The blue arrows indicate Zhurong’s path south from its landing spot at the top and ending near the bottom of the picture after traveling about 1,400 feet.

According to the paper, the TARs were formed by the prevailing winds over many eons, coming first from the north and then from the northwest. The edges of the ridges, being smaller, are pushed ahead quicker, thus creating the curved shape. The polygons were small, never larger than 4 inches in size, with five to six sides. The scientists theorize that they were formed when atmospheric water interacted with the dune crust, causing fractures “due to temperature/moisture changes or deliquescence/dehydration cycling of salts”. This process could be slow or fast, and could actually be occurring in relatively recent times, as the scientists say it requires only a little water in the atmosphere.

More likely however we are seeing evidence of water from the past, from tens of thousands to several million years ago.

Zhurong meanwhile remains in hibernation, and might never come out of that condition. Orbital images indicate that its solar panels are dust-covered, the result of the heavy winter dust storm season. The project team however is hopeful that with time and the arrival of Martian summer the dust will be blown off and they can reactivate the rover. This hope however entirely depends on the arrival of a dust devil acoss the top of Zhurong, a random event that cannot be predicted. With both the Spirit and Opportunity rovers, such events happened regularly, allowing those missions to last years instead of only 90 days. With InSight it never happened, and the lander died after two-plus years on Mars.

Zhurong’s future fate thus remains unknown, but not promising at this moment.

New map of the volcanoes of Venus

11:27 am

Map of Venus' volcanoes
Click for original image.

Using the archival radar data from the Magellan orbiter that circled Venus in the early 1990s, scientists have produced a new map of the volcanoes of Venus.

That map is to the right, and is publicly available for download.

Byrne and Hahn’s new study includes detailed analyses of where volcanoes are, where and how they’re clustered, and how their spatial distributions compare with geophysical properties of the planet such as crustal thickness. Taken together, this work provides the most comprehensive understanding of Venus’ volcanic properties — and perhaps of any world’s volcanism so far … because, although we know a great deal about the volcanoes on Earth that are on land, there are still likely a great many yet to be discovered under the oceans. Lacking oceans of its own, Venus’ entire surface can be viewed with Magellan radar imagery.

Although there are volcanoes across almost the entire surface of Venus, the scientists found relatively fewer volcanoes in the 20-100 km diameter range, which may be a function of magma availability and eruption rate, they surmise.

This new map catalogs about 85,000 volcanoes, but is also considered incomplete because the resolution of the Magellan data makes identifying volcanoes smaller than 1 kilometer impossible. It will require new orbiters to spot these volcanoes.

Looking back from the foothills of Mount Sharp

Panorama looking back across Gale Crater, March 29, 2023

Overview map
Click for interactive map.

The panorama above, cropped to post here, was taken today by the left navigation camera on the Mars rover Curiosity. It looks back at the rover’s previous travels, though only the terrain traveled in the past few months is visible, the rover having reached this point through the notch to the left of the distinctly dark mesa in the center of the picture. The lower flanks of Mount Sharp the rover traversed to get here are now blocked from view.

Instead, the image provides a spectacular example of the views north from Curiosity’s present position. The overview map to the right provides us the full context of the entire ten-plus year journey since Curiosity landed safely on Mars on August 5, 2012. The white squiggly line indicates the rover’s route. The yellow lines mark the approximate area covered by the panorama. The rim of Gale Crater is about 20-25 miles away.

As you can see, as spectacular as this view is, the journey up Mount Sharp has barely begun. Mount Sharp’s peak is about 18,000 feet high. The rover at this point has only climbed about 4,600 feet from the floor of Gale Crater.

Click for original image.

The science team for Ispace’s Hakuto-R1 privately-built lunar orbiter/lander earlier this week released the spacecraft’s first picture of the Moon since entering lunar orbit on March 20, 2023.

That image is to the right, cropped and reduced to post here. The photo resolution is quite good. It also demonstrates that the spacecraft’s attitude control systems for pointing the camera are working correctly.

Launched on December 11, 2022 by a Falcon 9 rocket, Hakuto-R1 will land in Atlas Crater on the northeast quadrant of the Moon’s visible hemisphere sometime in April, making it the first successful private commercial planetary lander to reach another world. If successful, it will then release the United Arab Emirates Rashid rover, that nation’s first planetary lander but its second planetary mission, following the Mars orbiter, Al-Amal, now circling Mars.

Israel launches spy satellite

9:04 am

Israel yesterday successfully launched a radar reconnaissance satellite using its Shavit-2 solid-fueled three-stage rocket.

This was Israel’s first launch since 2020. It took place from Israel’s coastal launchpad, and traveled west over the Mediterranean so that its stages would not fall on habitable areas. This retrograde orbit, opposite of the Earth’s rotation, is costly in terms of fuel and the size of payload put in orbit, which is why the satellite weighed only 661 pounds.

The leader board for the 2023 launch race remains the same:

20 SpaceX (with a planned launch later today)
11 China
5 Russia (with a planned launch later today)
3 Rocket Lab

American private enterprise still leads China 23 to 11 in the national rankings, and the entire world combined 23 to 20. SpaceX now trails the rest of the world, including other American companies, 20 to 23.

Midnight repost: Genocide is coming to America

12:02 am

Rick, stating the truth in Casablanca
Will the murder and mutilation of innocent children
finally wake Americans up?

Considering the recent horrible murders of three young school children as well as three adults at Covenant School, a Christian elementary school in Nashville, merely because some sexually confused woman (not a “trans-person” as the insane insist we call her) decided it was her right to murder people, I thought it might be worthwhile to post my essay below from July 2020. In it I predicted that mass murder by the left was only around the corner, if the good people of America did not finally wake up and take seriously the madness that is taking over that part of the political spectrum.

I am still unsure whether ordinary decent Americans have finally awakened, but it appears the recent school violence might finally be providing the spark. We shall see.

Genocide is coming to America

In my last visit to Israel in 2018, my brother and sister-in-law took me sight-seeing to the northern parts of Israel near the Sea of Galilee. On our first night, we stayed at the home of one of their older friends, a man in his seventies.

That night we sat around their kitchen table so that they could catch up on family matters. At one point in the conversation our host reminisced about an older woman, now gone, who he had known in his childhood in the 1950s who had lived in Germany before and during World War II and had survived a concentration camp.

To paraphrase the story he told us, what this woman always remembered most starkly about that time, especially in the 1930s, was how difficult it was to get German friends who were not Jewish to believe the horrors she and other Jews were going through. To her, their calm nonchalant dismissal of the Nazi bigotry and oppression of Jews — too unbelievable to take seriously — was what had horrified her the most. Even twenty years later, it was this dismissal that appalled her the most, despite her time in a concentration camp and the death she had seen around her.

As he told us this story, what struck me was how similar my own experience has been. Time after time for the past four decades my liberal friends and relatives have refused to believe anything I say to them — always based on actual events — about politics and the growing corruption and bigotry within the Democratic Party. Like those decent Germans in the 1930s, these decent Americans find reasons to quickly dismiss what I say, without making any effort to find out if there is any merit to it.

In fact, less than two days after this very conversation it happened again. » Read more

Mars’ largest mountain region

1:05 pm

Mars' largest mountain region
Click for original image.

The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on September 21, 2015 by the context camera on Mars Reconnaissance Orbiter (MRO). I originally was going to post a high resolution image of some of these mountains, taken on January 1, 2023 that showed some slope streaks, but quickly realized that a wider view of this mountain region was a much more interesting story.

This picture covers an area about 50 by 50 miles. As you can see, it is endless series of random hills ridges and peaks, with only a vague hint of a northeast to southwest alignment. Ground travel through this region would be slow and twisty, immediately reminding me of my many trips to West Virginia, where the hills and valleys are almost as random and never ending.

The overview map below however suggests the scale of this region exceeds West Virginia many times over.

NASA goes woke!

9:39 am

NASA yesterday announced that it has named two individuals, based on their race and gender, to lead the agency’s effort to promote the Marxist and racist Diversity, Equity, and Inclusion (DEI) movement.

NASA Administrator Bill Nelson announced Monday he is taking additional steps forward to advance diversity, equity, inclusion, and accessibility (DEIA) at the agency. Nelson named Steve Shih to serve in a new position as the agency’s first Diversity Ambassador and selected Elaine Ho as the next associate administrator for the Office of Diversity and Equal Opportunity at NASA Headquarters in Washington, effective immediately.

…As diversity ambassador, Shih will further NASA’s DEIA initiatives by building key strategic alliances with external partners, enabling NASA to continue being a model agency and leader for DEIA. In this role, Shih will engage NASA’s partners – including across the government, private sector, academia, and non-governmental organizations – to learn and promote best practices for NASA to recruit, hire, engage, and retain the most talented individuals from all backgrounds and life experiences. With his experience leading the Office of Diversity and Equal Opportunity since 2017, Shih will build on his three decades of federal expertise and help NASA continue to enable everyone to contribute inclusively to NASA and to the United States.

As Shih transitions to the role of diversity ambassador, Ho will bring extensive DEIA expertise to the Office of Diversity and Equal Opportunity. She most recently has served as the deputy associate administrator for NASA’s Office of STEM Engagement, leading a wide-ranging portfolio of projects benefiting students, universities, and educational institutions across the country to inspire, engage, and educate the Artemis Generation.

To further prove NASA’s commitment to favor some races over others, the agency also announced yesterday that it is committing $3 million to support “seven Historically Black Colleges and Universities (HBCUs) and one Predominantly Black Institution (PBI).”

Note the focus on race, not achievement. While it is nice to help the disadvantaged, these programs are not really aimed at that goal. Instead, this entire DEI movement is designed to give power to specific races, to the detriment of others. Or to put it more bluntly, it is a race-based apartheid system that encourages race hatred and resentment.

It is also probably illegal, based on the Civil Rights Act of 1964. Of course, the law is now irrelevant when it comes to the new racism. Supporters of DEI are allowed to break it whenever they want, because clearly they are superior to all others and have that right.

Finally, this stuff has absolutely nothing to do with NASA’s fundamental purpose, which is to help American industry more successfully explore space. It is instead a return to the Obama administration’s policy of making NASA’s most important priority that of helping minorities. Then it was Muslims, now it is the alphabet soup of LBGQTBIPOCZXYZ (and so on).
