Lava flooded mountains on Mars
Click for full image.
Today’s cool image to the right, rotated, cropped, and reduced to post here, was taken in January 2012 by the context camera of Mars Reconnaissance Orbiter (MRO). The location is a small section of the Tartarus mountain range that is cut by the Cerberus Fossae fissures, all located in Elysium Planitia, the large volcanic lava plain that lies between Mars’ big volcanoes. The white cross on the overview map below marks the location of the photo.
I picked this photo because it quickly shows us in one picture many of the typical features one finds in that lava plain.
For example, the distinct fissure that cuts across the mountains near the top of the picture is the northernmost large fissure of Cerberus Fossae. In my initial post on Cerberus I mistaken thought its large and many hundreds of miles-long fissures might be evidence of underground lava tubes. Since then I have learned while the depressions may signal underground voids, they are not a lava tubes but graben, cracks formed by the movement of the terrain on each side. The cracks opened when past volcanic activity caused the ground to swell upward, stretching and splitting it.
The dark splotch in the flat area just south of the fissure remains me of the maculae found in these lava plains to the west of Olympus Mons, splotches that for still undetermined reasons dust devils like to congregate, blowing off the red dust so that the dark basalt lava becomes visible. No high resolution image of this spot has yet been taken, so this is a pure guess on my part.
The mountains near the bottom of the photo illustrate the ancient lava flood that inundated these mountain peaks. The white box shows the area covered by the recent MRO high resolution image that I include below.

Biden administration’s proposed ’22 NASA budget boosts spending in all programs
The just released summary budget by the Biden administration for 2022 includes a $1.5 billion increase in NASA’s budget, with increases for every NASA project across the board.
Maybe the only part of this that is surprising is the $325 million increase to the manned Artemis project to return to the Moon. Democrats have traditionally tried to cut such programs, even as they increased the spending in NASA’s climate budget. Though the Biden administration has shown that its priorities remain in line with this by increasing NASA’s climate budget by a hefty $2.3 billion, it did not cut Artemis but increased its budget also.
This budget proposal is also in line with the general trend in Washington, which is to spend money as if it grows on trees. Trump had also increased NASA’s budget, but tried to counter those increases with cuts in other areas, both in NASA and elsewhere. None of his proposed cuts however were ever really approved, as Congress has no interest in cutting anything.
Now that Biden and the bureaucracy is in power the money to them is going to flow like water from a burst dam. Whether the American people actually benefit from this spending remains to be seen. In general, since the 1960s the payoff from increased federal spending has been poor to terrible. I don’t see any reason to expect otherwise, even if the support of manned space exploration by the Biden administration helps fuel a new commercial renaissance in space. That renaissance cannot last if the country that supports it goes bankrupt.
Starship #11 debris fuels environmentalist opposition
They’re coming for you next: The debris that fell as far as five and a half miles away when SpaceX’s Starship #11 prototype exploded just before landing on March 30th has increased the already vocal opposition from various environmentalist activists of the space project.
Environmental organizations such as the Sierra Club, the Friends of Wildlife Corridor, and concerned citizens in the environmental research field have expressed their dissent about the SpaceX activities at Boca Chica.
Chris Sandoval, a science teacher in Brownsville with degrees in Wildlife and Fisheries and Ecotoxicology, has put forth a research paper explaining the possible effects of SpaceX activity in the surrounding natural habitats and economic consequences as a result of their expansion in the region.
Sandoval says research would show that contamination from rocket fluids would harm wildlife in the surrounding area. “Contaminants such as those of hydrocarbons are able to kill aquatic life, both vertebrate and invertebrate, at very low concentrations, especially when it’s in a semi-enclosed area as the Lagunas are,” explained Sandoval.
And yet, none of these claims seem to apply to the government-run spaceports in Florida and California, both of which are also surrounded by wildlife refuges. Why is that? Why do these environmentalists have a particular opposition to the spaceport of this private company, but none or little opposition to the government’s? Could it be that what they really oppose is private enterprise, and are using the environment as a tool to destroy it?
I should add, according to the U.S. Fish and Wildlife Service that manages this refuge, SpaceX has been working closely with them on mitigating the damage, which in the end I suspect will be quite minimal. The ecology is far stronger than these environmentalist like to portray it. What SpaceX did hardly compares to the damage a hurricane would cause, and that is not an unusual event at this Gulf coast location.
Whether this environmental opposition to SpaceX will result in any major delays or obstacles remains to be seen. Under a Trump administration I would not be too concerned. Under today’s Democratic Party Biden administration, who knows? The tendency of Democrats is to regulate, and to use their power to squeeze others. So far that has not yet happened aggressively in connection to SpaceX, though there have been signs that the Biden administration is interested in increasing the regulatory roadblocks SpaceX must face. We will only have to wait and see.
Above all this increases the urgency for SpaceX to shift as soon as possible its Starship and Super Heavy test flights to the two oil-rigs it purchased and are refitting as floating launch and landing platforms. Once the bulk of those test flights are far away, out in the ocean, the political clout of these protesters will be minimized.
Today’s blacklisted American: Dennis Prager and his organization PragerU
They’re coming for you next: Joining a host of other big tech software companies in their blackballing of the website PragerU, founded by radio host Dennis Prager, the Chinese owned social media ap TikTok placed its own permanent ban on the site this week.
According to PragerU, TikTok claims the ban is because of “‘multiple violations’ of their community guidelines,” a claim that is utter garbage and a lie. PragerU is simply a conservative website touting the traditional American ideals of life, liberty, personal responsibility. Because these are values that the dominant socialist and Marxist culture in both America and China oppose, PragerU must therefore be censored.
Nor has TikTok been alone among the social media giants in its blacklisting of PragerU. Facebook, YouTube, and Spotify have all taken actions to either block the site and its videos or prevent people from finding them. In every case the reasons cited are always either “a mistake” or a claim that PragerU violated some vague unstated “community standard.”
Make no mistake. The people who work for these big social media companies want to squelch any dissent from the modern Marxist agenda, and will do whatever they can to censor that dissent. Expect this blacklisting to get worse in the next few years, especially because these tech bullies are discovering they pay no penalty for doing so.
Starship and Super Heavy update
Link here. The fifteenth Starship prototype has now been moved to its launchpad, which you can see here, while further work continues on Starship prototypes #16-20, the first Super Heavy prototypes, #1 and #2, and the orbital launchpad.
Starship #15 sports many changes in design from #11, and is expected to do its first test flight sometime in the coming weeks. As for the first Super Heavy prototype, it will be used to test some ground operations as well as the prototype itself, on the ground. Prototype #2 will hopefully make the first Super Heavy hop.
The construction of a full orbital launchpad lends great weight to SpaceX’s goal of making the first orbital flight before the end of the year.
Meanwhile, SpaceX has likely tightened security at this Boca Chica facility after a youtuber sneaked onto the site recently and posted video of himself wandering around the base of Starship #11, unmolested. He has since removed that video, but another youtuber grabbed it and has re-posted it for you to watch.
X-37B testing beamed solar power from space
The U.S. Space Force’s X-37B mini-shuttle, presently in orbit for more than 300 days, is testing technology for capturing solar energy and beaming it back to Earth for use in the electricity grid.
Most of the robotic space drone’s duties on this mission, known as Orbital Test Vehicle-6 (OTV-6), are a tightly held secret. However, one known bit of research that the craft carries is the Photovoltaic Radio-frequency Antenna Module Flight Experiment, or PRAM-FX.
PRAM-FX is a Naval Research Laboratory (NRL) experiment that’s investigating transforming solar power into radio frequency (RF) microwave energy. PRAM-FX is a 12-inch (30.5 centimeters) square tile that collects solar energy and converts it to RF power.
Paul Jaffe, the innovation power beaming and space solar portfolio lead at NRL, said that PRAM-FX is not beaming microwave energy anywhere. Rather, the experiment is gauging the performance of sunlight-to-microwave conversion. To be measured is how the PRAM is performing from an efficiency standpoint and also from a thermal performance stance, he said.
The first results from PRAM were released in January, and showed an “8% total module efficiency,” which I think means it was able to beam down 8% of the solar energy that it gathered. This might seem poor, but if solar panels can provide that much of their energy for Earth use the pay-off could be quite large.
A much larger demonstration project will fly three different spacecraft in ’23 and ’24, each testing different components of the system.
Commercial Japanese company about to test orbital space junk removal
Capitalism in space: The private Japanese company Astroscale has placed in orbit a satellite dubbed ELSA-d to test the use of magnets for capturing and removing space junk from orbit.
ELSA-d was launched March 22nd as part of a Soyuz commercial launch.
The ELSA-d mission will test new technology developed by Astroscale, which consists of two satellites stacked together: a 385-lb. (175 kilograms) “servicer” and a 37-lb. (17 kg) “client.” The servicer is designed to safely remove debris from orbit, while the client spacecraft will serve during the demonstration as a piece of debris to be cleaned up. Once the two satellites separate, they will perform a cosmic game of cat and mouse over the next six months.
…Using a series of maneuvers, Astroscale will test the satellite’s ability to snatch debris and bring it down toward the Earth’s atmosphere, where both servicer and debris will burn up. The servicer is equipped with a magnetic docking plate, as well as GPS technology to estimate the exact position and motion of its target. This debris removal demonstration project is the first of its kind by a commercial satellite operator, according to the statement.
During the trial mission, the company will test whether the servicer can catch the client satellite in three separate demonstrations.
The company’s goal is to convince satellite companies to place its client component on their satellites so that when it comes time to decommission the satellite Astroscale’s servicer can be sent up to remove it.
Rocket Lab to recover 1st stage on next flight
Capitalism in space: Rocket Lab yesterday announced that in its continuing program to make the first stage of its Electron rocket reusable, it will attempt to recover the stage after splashdown in the ocean during its next launch in May.
While Electron’s second stage delivers the satellites to orbit, Electron’s first stage will undertake a series of complex maneuvers designed to enable the stage to survive the extreme heat and forces of atmospheric re-entry on the way back to Earth.
As the rocket reaches speeds of around eight times the speed of sound on its descent, the air around Electron heats up to 2,400 °C generating an extremely hot plasma that creates a red-orange glow around the re-entering stage. Because Electron will enter the atmosphere engines first, the nine 3D printed Rutherford engines on the first stage will bear the brunt of this extreme heating. To withstand the immense temperatures, this Electron features an evolved heat shield designed to protect the engines and direct the force of the plasma away from the rocket. After entering the atmosphere, Electron will deploy a drogue parachute to help begin the process of slowing the rocket down and stabilizing its descent. Once Electron is at subsonic speeds, a circular parachute is deployed to help further slow the rocket in preparation for a gentle ocean splashdown. A Rocket Lab vessel will then rendezvous with the stage in the splashdown zone, approximately 650 km from Launch Complex 1, and retrieve it for transport back to Rocket Lab’s Production Complex for inspection.
They did the same thing on the previous launch. This second test will be to validate what was learned then.
If all goes as planned, they hope the next recovery attempt will be an in-air snatch by a helicopter, before the stage hits the water. If that is successful that stage will then be capable of re-use.
Soyuz-2 launches three astronauts to ISS
Russia today successfully used its Soyuz-2 rocket to launch three astronauts to ISS.
Because this flight is occurring three days before the 60th anniversary of Yuri Gagarin’s first human flight in space, the Russians gave the Soyuz capsule his name to honor him and the event. The spacecraft docked with ISS only two orbits later.
The crew also included an American, Mark Vande Hei, who is flying as part of the new barter agreement with Russia, whereby Americans fly in Soyuz in exchange for Russians flying in American commercial capsule. This was the first time NASA paid nothing for a flight on Soyuz since the shuttle retired a decade ago.
The return to Earth of Vande Hei and his fellow crew member Pyotr Dubrov will be on the next Soyuz capsule to launch in October, MS-19, in order to accommodate a short visit by a Russian movie director and actress.
Roscosmos will launch Soyuz MS-19 no earlier than October 5 with Commander Anton Shkaplerov and two civilian spaceflight participants. Russian film director Klim Shipenko and a Russian actress, who is yet to be named, will film a movie called “The Challenge” and spend approximately a week aboard the ISS before returning to Earth aboard Soyuz MS-18 with Novitsky.
With this commercial manned flight there will be two such flights in the fall, the Dragon Inspiration4 flight that will not dock with ISS and this Russian one. Both will then be followed by the Axiom commercial tourist flight on a Dragon capsule early in ’22. Expect such commercial manned flights to become somewhat routine in the coming years.
UPDATE: China also launched an Earth observation satellite yesterday, using its Long March 4B rocket
The leaders in the 2021 launch race:
10 SpaceX
8 China
6 Russia
2 Rocket Lab
The U.S. still leads China 14 to 8 in the national rankings.

Mars’ icy high latitudes
Click for full image.
Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on November 29, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Labeled simply as “periglacial survey,” it is one of almost two hundred such images taken by MRO over the years, almost all of which are in the high latitudes above 60 degrees, with most being in the southern hemisphere. Most appear to be close to or above Mars’s Arctic Circle, which means these are locations that will see little or no sunlight for a portion of the year.
I have been unable to contact the scientists doing this survey, so I will have to make an educated guess as to its purpose and goals. “Periglacial” refers to the outer fringes or margin of a glacier or large ice sheet. Thus, in the context of this survey, the scientists appear to be studying places where they think the Martian high latitude ice sheets are beginning to sublimate away. Today’s photo is a good example. It is located at 67 degrees south latitude, in the southern cratered highlands but in an area that appears to be relatively free of craters. Instead, the terrain appears somewhat flat with only periodic depressions and scarps. The MRO context camera photo below of the same area, rotated, cropped, and expanded to post here, illustrates this.
