SpaceX raises another $1.16 billion in private capital

9:25 am

Capitalism in space: In a regulatory filing yesterday SpaceX revealed that it raised another $1.16 billion in private investment capital in just the past two months.

This follows two other recent financing rounds since August of last year in which SpaceX raised almost $3 billion. That makes $4 billion raised in eight months. All told, I think this brings the total private investment capital SpaceX has raised in the past two years to approximately $6 billion, all for building both the Starlink satellite constellation and the Starship/Superheavy rocket.

Not only does this give SpaceX ample cash to build both, it signals the growing faith big money investors have in the company’s plans. They have bought into Elon Musk’s dreams because he has proven that his dreams deliver, not only in exciting space ventures but in profits.

This fund-raising success also tells us that even if Starship does not reach orbit before SLS, it will very soon eclipse it entirely. It has the money now to get built, and the way SpaceX builds things, it will get built fast.

Russia to build own space station; admits Zvezda is failing

9:10 am

Zvezda module of ISS
The Zvezda module, with aft section indicated
where the cracks have been found.

The new colonial movement: On April 12th, the 60th anniversary of the flight of Yuri Gagarin, Russian President Vladimir Putin announced that Russia is going to build its own independent space station, dubbed the Russian Orbital Space Station (ROSS), to replace its half of ISS.

More important however was this carefully worded admission:

In recent years, the ISS has begun to fall apart, with astronauts now frequently discovering cracks. Last week, it was revealed that Russian cosmonauts were still working on plugging a leak first noticed in 2019. The ongoing problems with the international station have prompted Moscow to begin creating a replacement.

What this state-run news article failed to mention is that the cracks and leaks have only been found in Russia’s twenty-year-old Zvezda module, not the rest of ISS. What ISS faces is the failure of the core section of Russia’s half of the station.

This public statement however is the first from Russia that clearly admits that the cracks in Zvezda are likely systemic stress fractures, and the patches to seal them are mere bandaids on a much more fundamental problem that is certain to get worse over time.

The decision to build its own new station is however not really surprising. The American goals in space have been shifting from promoting the government’s program to stimulating the American commercial aerospace industry. International cooperation is no longer the primary goal. The American foreign aid to Russia’s space program from the early days of ISS’s construction has long ago dried up, and Russia is also no longer getting any cash from the U.S. to fly American astronauts to ISS. The incentive to remain a partner has vanished.

If successful this will make three national stations in orbit, ISS, China’s, and Russia’s. In addition, we should start seeing the launch of several private commercial stations sometime this decade.

The competition is going to be glorious, with the results fast-paced and exciting. The moribund days of boring international cooperation where everything was squeezed into a single project, the International Space Station, appear over.

Evidence of glaciers in the Martian equatorial regions?

1:45 pm

Equatorial crater with glacial features?

Cool image time! The photo to the right, cropped and reduced to post here, was taken on February 2, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO) and was labeled as “Exhumed Craters Exhibiting Concentric Fill”.

The term “Concentric Fill” is used by planetary scientists to mark glacial-type features frequently found inside craters at latitudes greater than 30 degrees latitude. This crater however is at 22 degrees north latitude, too close normally to the equator to expect a buried glacier inside it. Any ice at such a latitude is expected to be underground and well protected. A debris covered glacier would likely sublimate away, which I think is why the scientists labeled this “exhumed.” Though there are the concentric features near its inside rim as well as covered by the sand dunes on the crater’s floor, they are assuming this is only evidence of past ice, no longer there. This assumption is strengthened by the splattered but eroded nature of the surrounding terrain. Such splats are typical of high latitude impacts in regions with ample buried ice. The eroded nature of this splat however suggests it is very old and has likely lost its ice.

Then again, this is an assumption.

Blue Origin completes another unmanned suborbital test flight of New Shepard

12:38 pm

Capitalism in space: Blue Origin today successfully completed another unmanned suborbital test flight of New Shepard, and in doing so also rehearsed the boarding and disembarking procedures they will use when they finally fly this craft with people on board.

Blue Origin personnel rehearsed how customers will board the six-seat crew capsule before Wednesday’s launch. Four employees stood in as astronauts and rode to the launch pad inside a Ford SUV with two support crew members.

After arriving at the pad, the astronaut stand-ins climbed stairs up the launch pad tower and walked across an access gantry leading to the spacecraft sitting atop the already-fueled New Shepard booster. Two employees — Gary Lai, Blue Origin’s New Shepard designer, and Audrey Powers, the company’s vice president of legal and compliance — entered the capsule through the hatch and strapped into seats. … After a few minutes, Lai and Powers exited the spacecraft and the crew evacuated the launch pad before liftoff.

…Blue Origin crews at the West Texas test site also practiced how they will help passengers out of the capsule after landing. Recovery teams quickly converged on the spacecraft after touchdown in the desert, and approached the capsule with mobile stairs and other equipment.

While rehearsing these procedures seems a good idea, there appears to be a bit of blarney in this whole show. Considering that this was their 15th New Shepard flight and the second for this spacecraft, it seems to me that these procedures could have rehearsed during one of those earlier flights, or even during any one of many dress rehearsal countdowns that they should have done previously, not on a flight itself.

Blue Origin has not announced when the first manned suborbital flight will be. In their last prediction in January they had said the first manned flight would happen in April, something that has now clearly not happened.

That flight is now more than five years behind schedule, based on the company’s promises back in 2016. when they flew New Shepard almost every other month and predicted the first manned flights in 2017. Then, Jeff Bezos hired Bob Smith to be Blue Origin’s CEO, and the company’s progress on New Shepard crawled to a stop.

It is now questionable whether this company will even get its first suborbital tourist flight launched before SpaceX completes its first orbital tourist flight in September. At that point why should anyone who can afford to pay for a space flight choose New Shepard and its mere five minutes of weightlessness when they go to orbit with SpaceX and spend days there? It might cost less, but it will still cost a lot, and the cost-benefit analysis sure doesn’t favor Blue Origin’s business model any more.

Today’s blacklisted American: A black conservative professor, because he is black

12:12 pm

The Declaration of Independence, cancelled
The Declaration of Independence, banned at Grace Church high school

The intolerant and insane blacklist culture that has taken over our government, our academic community, the entertainment field, and corporate America has reached a new low with today’s story.

When Paul Rossi, a teacher at the private Grace Church high school in Manhattan, decided to assign his students readings by Glenn Loury, a moderate black conservative professor, the school’s head, George Davison, told him to remove those books and instead assign books by “mainstream white conservatives.”

Rossi wrote that since “the BLM [Black Lives Matter] protests often came up in our discussions, I thought of assigning Glenn Loury, a Brown University professor and public intellectual whose writings express a nuanced, center-right position on racial issues in America. Unfortunately, my administration put the kibosh on my proposal.”

“The head of school responded to me that ‘people like Loury’s lived experience—and therefore his derived social philosophy’ made him an exception to the rule that black thinkers acknowledge structural racism as the paramount impediment in society,” Rossi wrote. “He added that ‘the moment we are in, institutionally and culturally, does not lend itself to dispassionate discussion and debate,’ and discussing Loury’s ideas would ‘only confuse and/or enflame students, both those in the class and others that hear about it outside of the class.’”

In other words, racism against a black man is perfectly okay if that black man happens to also disagree with the Marxist and clearly bigoted philosophies of Black Lives Matter.

If you read Rossi’s full column describing this event and the situation at Grace Church high school, you will discover that the school’s bigoted culture is even worse than that.

More delays to Boeing’s Starliner manned capsule schedule

9:52 am

Capitalism in space: Though no new launch date has been announced, both NASA and Boeing are now likely aiming for a summer launch of the second unmanned Starliner demo mission to ISS.

This is largely due to traffic at the International Space Station rather than the readiness of Starliner itself. Two NASA sources said the vehicle is “close” to being ready, with only a few small tests to certify the spacecraft for flight remaining. Starliner is therefore expected to be ready to fly by early summer.

The primary issue is the availability of space station docking ports fitted with an “international docking adapter,” which are used by SpaceX’s Crew Dragon, Cargo Dragon 2, and Starliner vehicles. There are presently two such ports on the station, and for NASA, the priority for access to these ports are crew rotations followed by supply missions. So the question becomes when the Starliner test flight can find an open slot on station.

It appears that they are now targeting the window of availability for either of those ports in the late July into August time period.

While this might be the main reason for this new delay, it also appears that there might be technical issues as well. In early March Boeing and NASA had announced that they were delaying this demo mission for the same scheduling reasons, but then they said they were targeting a May launch date, during a period after one manned Dragon mission had left in late April and before the next Dragon cargo mission arrived in June.

It now appears they cannot meet that window any longer, and are therefore aiming for the next, in July.

Meanwhile, the first manned Starliner demo mission appears to have also pushed back, from late this year to early next year.

SpaceX’s Falcon Heavy wins launch contract for VIPER lunar rover

9:39 am

Capitalism in space: Astrobotic, the company building the lander to place NASA’s VIPER lunar rover on the Moon, has picked SpaceX’s Falcon Heavy as the rocket to launch the package.

This mission is part of a fleet of landers being sent to the Moon in the next two years, as part of NASA’s Commercial Lunar Payload Services (CLPS) program to hire private companies to do this rather than NASA.

Intuitive Machines, which won CLPS task orders for two lander missions, will launch each on Falcon 9 vehicles late this year and in 2022. Masten Space Systems selected SpaceX to provide launch services for its XL-1 lander mission, which won a CLPS award for a late 2022 mission.

Astrobotic will launch its first CLPS mission, a smaller lunar lander called Peregrine, on the inaugural launch of United Launch Alliance’s Vulcan Centaur currently scheduled for late this year. Firefly Aerospace, which won the most recent CLPS award in January, has not selected a launch provider yet for its Blue Ghost lander, but noted the lander is too large to launch on the company’s own Alpha rocket.

That’s five American lunar missions, all built and owned by private companies. Nor will these be the only unmanned lunar missions, when you include the UAE rover targeted for a ’22 launch, along with additional planned Indian, Chinese, and Russian missions. Almost all are aimed at the Moon’s south polar regions.

It is going to get both crowded and busy on the Moon in the next few years.

UAE hires Japanese company as partner for its ’22 lunar rover mission

9:34 am

Capitalism in space: The United Arab Emirates (UAE) has chosen the private Japanese company Ispace to provide the lander bringing its Rashid rover to the Moon in 2022.

ispace’s 240 kg lander is 2.3 meters tall and 2.6 meters wide. It will be launched by SpaceX, Elon Musk’s rocket company, on a Falcon 9 rocket. Once the iSpace lander is placed in the Earth’s orbit, it will travel to the moon on its own, land and unload the rover.

The lander will use solar panels for power, which will also allow the rover to communicate with Earth. It will also carry a solid-state battery made by NGK Spark Plug, which intends to examine its battery’s lunar performance.

This UAE project is similar but a step up from its Al-Amal Mars orbiter. In that case UAE used its money to have the orbiter mostly built by U.S. universities as they taught UAE’s students how to do it. In this case, UAE engineers appear to be building the rover itself, with the purchased help of others to provide the lander..

A lonely dry lava spring on Mars

2:19 pm

A lonely dry lava spring on Mars
Click for full image.

Today’s cool image from Mars takes us to the southern flank of the giant volcano Pavonis Mons. The photo to the right, rotated, cropped, and reduced to post here, shows what appears to be a volcanic vent from more than a billion years ago when it is believed Pavonis was actively erupting. The picture was taken on March 2, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The grade is mostly downhill to the east and south east.

It is very possible that this is the resurgence of a lava tube, the point where the underground flow either emerged to the surface or got so close to the surface that the ceiling was thin enough to later collapse, creating this depression. No pits or skylights are visible in this high resolution picture, however, so whether there is an underground lava tube here is not known, an unknown that is amplified by the wider MRO context camera image below.

Today’s blacklisted American: A congresswoman because she speaks her mind

1:16 pm

The cancelled Bill of Rights

They’re coming for you next: Since her election in November 2020 Republican Congresswoman Marjorie Taylor Greene (R-Georgia) has repeatedly irritated many people for her strong and very outright conservative opinions on everything from election fraud to religion to Donald Trump and Joe Biden.

As a result she has become the target by many on the left, resulting in her Twitter account being suspended more than once. In one case it was because she had said posted a tweet celebrating Easter and glorifying the resurrection of Jesus. In another case it as because she called for the supporters of Trump to rally against election fraud and the possibility that the 2020 presidential election was stolen. In both cases her account was reinstated by Twitter within twelve hours, with the social media platform claiming the first suspension was a mistake while the second was not (having violated Twitter’s partisan rules that forbid anyone from suggesting that there might have been election tampering that led to Biden’s victory).

These Twitter attacks are ugly and illustrate that platform’s anti-Republican and leftist agenda, but it is still a private company. More important have been the efforts to muzzle Greene in Congress, led by the Democrats.

New calls for reworking or replacing Outer Space Treaty

10:53 am

Yesterday there were two different public statements calling for the international community to either amend or replace the Outer Space Treaty, one an op-ed in the U.S. and the other a statement by the head of Russia’s space agency.

At first glance these announcements seemed hopeful, especially because the op-ed, written by one of the authors of a just released new study [pdf] by a defense-oriented Washington think tank, made part of its focus the need to encourage commercial activities in space.

Commerce increases sanctions on Russia impacting space commerce and trade

9:47 am

The Commerce Department last month announced that is increasing the level of sanctions against trade with Russia because it had determined that country had violated international law by using chemical weapons against specific dissidents both in and out of Russia.

On March 4, 2018, the Russia Government deployed a Novichok nerve agent in an attack against former Russian military officer Sergei Skripal and his daughter Yulia Skripal in the United Kingdom. In response, the U.S. Government imposed two sets of sanctions against Russia pursuant to the Chemical and Biological Weapons Control and Warfare Elimination Act of 1991 (CBW Act) in August 2018 and August 2019.

On August 20, 2020, the Russian Government again deployed a Novichok nerve agent, this time against Russian opposition figure Aleksey Navalny, warranting a new determination by the Secretary of State and additional sanctions under the CBW Act.

While this ruling will have a negative impact on any space-related U.S./Russian activities, the full ruling specifically included these waivers:

Ingenuity requires software update before flying

9:10 pm

JPL engineers have determined that they need to upload a software update on Ingenuity in order to solve the issue that caused the first high-speed spin test of its rotary blades to end prematurely.

In an update released late Monday by NASA’s Jet Propulsion Laboratory, mission managers said engineers identified a software fix for the “command sequence issue” that ended the high-speed spin-up test Friday.

Officials at JPL, which manages the Ingenuity helicopter project, did not announce a new target date for the rotorcraft’s first test flight. Ground teams hope to determine a new target date next week for the helicopter’s first flight.

According to the original plans, Ingenuity was to get about a 30 day test period, after which Perseverance would move on to its primary Mars science mission. It is not clear at this moment whether that test period will be extended because of these issues. I suspect they will extend it to get as many flight tests as possible, since Perseverance is functioning like a dream and can wait a few extra weeks before beginning what will be years of Martian roving. How often does one get to flight test a helicopter on another world?

Northrop Grumman’s MEV-2 successfully completes docking to commercial satellite

4:28 pm

MEV-2 about 50 feet away from satellite

Capitalism in space: Northrop Grumman today announced that its second Mission Extension Vehicle (MEV-2) has successfully docked with an Intelsat geosynchronous communications satellite.

Northrop Grumman is the only provider of flight-proven life extension services for satellites, and this is the second time the company has docked two commercial spacecraft in orbit. The company’s MEV-1 made history when it successfully docked to the Intelsat 901 (IS-901) satellite in February 2020. Unlike MEV-1, which docked above the GEO orbit before moving IS-901 back into service, MEV-2 docked with IS-10-02 directly in its operational GEO orbital location.

…Under the terms of Intelsat’s satellite life-extension servicing contract, MEV-2 will provide five years of service to IS-10-02 before undocking and moving on to provide services for a new mission.

The image, provided by Northrop Grumman, was taken by MEV-2’s infrared wide field of view camera when it was still about 50 feet away from the Intelsat satellite. You can see the Earth in the background. As I understand it, MEV-2 uses the satellite’s own engine nozzle as a docking port, which is the smallest circular feature in the center of the satellite. If you look close you can see the nozzle’s shadow on the right.

NASA/Boeing begin prepping SLS core stage for transfer to Florida

3:53 pm

NASA & Boeing have now agreed that the static fire test program of the core stage of their SLS rocket has ended successfully, and have begun preparing the stage for its shipment to Florida where it and the entire rocket will be assembled for launch.

While refurbishment activities continue, the team at Stennis has also started disconnecting the stage from the test stand to prepare for departure from Stennis. Weather will be a key factor in when the stage can be put on board the agency’s Pegasus barge to start the waterway tow trip from Stennis to Kennedy, but a late-April arrival at KSC is still possible — with KSC schedules currently forecasting attachment of the Core Stage to the SLS Boosters in the Vehicle Assembly Building in mid-May to prepare for launch of Artemis 1.

Though NASA still has a target of November for launch, NASA engineers estimate that it will take ten months to get the core stage in place and ready for launch. This places launch more likely in the February-March ’22 time frame. This schedule of course does not include any possible additional problems along the way, which may delay the launch further.

Even if all goes now as NASA plans, consider the length of this schedule. Though NASA will not require future SLS launches to do a static fire test, just transporting the stage and getting the rocket assembled will likely always take about this long, give or take a few months. Even if NASA streamlines this operation over time, I can’t see it getting shortened to less than five months. That means it will likely be impossible to launch more than one or maybe two SLS rockets per year, a pace that is not very effective if you really want to achieve anything in space. Moreover, that very very optimistic pace would cost about $3 to $5 billion per year, money that has not been appropriated, though considering Congress’s nonchalant attitude towards printing money these days that might not be a problem.

In the end, this rocket as designed is simply not practical or sustainable. It is a financial house of cards, and as soon as a more effective competitor like Starship (or even New Glenn) arrives that house will fall.

In fact, I still consider the odds of Starship/Super Heavy completing an orbital launch before SLS to be better than 50-50. With a likely spring ’22 SLS launch date and SpaceX aiming for a Starship orbital flight in ’21, the odds of SpaceX winning this race I think has just improved.

The start of avalanche season at Mars’ north pole

12:36 pm

A narrow ridge with avalanches
Click for full image.

Every spring for the last seven Martian years scientists have eagerly aimed the high resolution camera on Mars Reconnaissance Orbiter (MRO) at the steep 1,500 to 3,000 foot high scarp at the edge of northern polar ice cap in order to capture images of what is Mars’s most spectacular annual event, the occurrence of tens of thousands springtime avalanches along that scarp.

Well, spring has returned to the northern hemisphere on Mars, and the scientists have begun another monitoring campaign. The photo to the right, cropped to post here, was taken on March 7, 2021 by MRO. It shows a particularly dramatic part of that scarp, a place where the scarp separates two curved alcoves and is thus narrowed down to a ridge about 1,000 feet high.

The nose of the ridge is sloping downward to the northwest, so the horizontal bands on its crest are actually evidence of older and older layers exposed as the elevation drops. The blue and black markings on the left slope are likely evidence of this season’s first avalanches, or might even be avalanches occurring as the picture was snapped! As explained to me by Shane Byrne of the Lunar and Planetary Lab University of Arizona during the last Martian avalanche season,

On Mars half of the images we take in the right season contain an avalanche. There’s one image that has four avalanches going off simultaneously at different parts of the scarp. There must be hundreds to thousands of these events each day.”

The overview map below shows the location of this picture, as well as all the other places the scientists have routinely monitored in the fourteen-plus Earth years since MRO reached Mars orbit.

Today’s blacklisted Americans: Trump supporters blackballed by employers

11:28 am

Survey graphic
Click for full image.

Blacklists are back and the Democrats got ’em: According to a new survey, those who publicly supported Trump or expressed conservative opinions on social media are being willingly blackballed by the hiring managers in corporate America.

A new survey of hiring managers provided to Secrets found that backing Trump on social media is the top reason to reject a job applicant.

The apparent reason: Human resources departments want to avoid “tiffs” between employees. “Likely to avoid future office tiffs, a significant portion of hiring managers admitted to negatively judging candidates based on the political content posted. For 27% of hiring managers, social media posts endorsing Donald Trump for president would negatively impact their decision to hire a candidate,” read the analysis of the poll done for Skynova, an online business software company.

While the list of political positions that causes employees heartburn in the graph above also includes some pro-Democratic Party positions — such as endorsing Joe Biden, supporting unions and a minimum wage — the majority are pro-Trump or conservative positions. Though there is a small chance you might be denied a job if you publicly stated your leftist beliefs, you almost certainly will be blackballed if you dared speak out against such beliefs.

Moreover, leftist workers are now eagerly looking for ways to blacklist conservative companies as well. From the survey:

UAE picks two more astronauts

10:31 am

The new colonial movement: UAE has announced that it has chosen two more astronauts to raise its astronaut corp to four, one of whom has already flown to ISS.

The UAE government announced it picked Nora AlMatrooshi and Mohammad AlMulla from a pool of 4,305 applicants to join the country’s small astronaut corps. They join Hazzaa AlMansoori and Sultan AlNeyadi, the first Emirati astronauts selected in 2018.

AlMatrooshi is the first woman selected as an Emirati astronaut. A mechanical engineer, she has been working for the National Petroleum Construction Company in the UAE. AlMulla is a pilot and head of the training department of the Dubai Police’s Air Wing Centre.

Obviously, for an Islamic nation to pick a woman to be an astronaut is significant, and indicates the UAE’s commitment to moderating the more oppressive aspects of its religion.

As significant however is the fact that all four of these UAE astronauts are now undergoing training in the United States. Previously UAE’s astronauts trained in Russia. Though the UAE has not announced when its next manned flight will be, and has also said it wants to use both American and Russia spacecraft, the training in the U.S. strongly suggests the UAE wants to buy an American flight next time, most likely on a SpaceX Dragon capsule.

CDC admits its almost impossible to catch COVID from surfaces

9:00 am

The CDC last week finally admitted what had been well determined since May of last year, that there is no point in endlessly cleaning all surfaces everywhere because there is practically no chance of catching COVID-19 from surface contamination.

Turns out the risk of getting COVID-19 from touching an infected surface is “generally” 1 in 10,000, according to a new CDC study. That means “that each contact with a contaminated surface has less than a 1 in 10,000 chance of causing an infection,” the CDC explained in a statement.

Instead, the virus is mainly transmitted via the air — which essentially defeats the purpose of all the disinfecting wipes, and business owners feeling the need to obsessively make certain everything in their respective establishments was thoroughly scrubbed.

Of course, the CDC is still demanding everyone wear masks, even though the research for decades shows that unless you wear the right kind of mask properly, it likely does more harm then good. At a minimum it is nothing more than empty theater, a recommendation that has nothing to do with science and data and everything to do with emotions.

From the beginning of this epidemic the CDC has failed at being a trustworthy scientific organization, instead making pronouncements not based on scientific research but on feelings and sometimes a political agenda (defeating Donald Trump). Until there is a real-house-cleaning in that corrupt organization, there is no reason for anyone to trust anything they say.

Ingenuity test flight delayed

12:08 pm

Due to a software issue identified during testing of the helicopter’s rotary blades, Ingenuity’s engineers have decided to delay its first flight for at least three days.

During a high-speed spin test of the rotors on Friday, the command sequence controlling the test ended early due to a “watchdog” timer expiration. This occurred as it was trying to transition the flight computer from ‘Pre-Flight’ to ‘Flight’ mode. The helicopter is safe and healthy and communicated its full telemetry set to Earth.

They are presently trouble-shooting the issue.

Ingenuity’s flight schedule

9:07 pm

Ingenuity’s first flight on Mars is now a go for late on April 11th, with the first data arriving in the early hours of April 12th.

The flight plan should that first flight go as expected is as follows:

The helicopter team has 30 Martian sols (roughly 31 days on Earth) to take the first tentative flights. Assuming Ingenuity survives the first flight, it will rest and transmit data before attempting a second flight with lateral movement. Subsequent flights will happen every three or four Martian sols. The fifth flight — if Ingenuity gets that far — will be a chance to really soar. “The probability is it would be unlikely it will land safely because we will go into unsurveyed areas,” Aung said.

They have unlocked and tested the rotary blades, with all working as planned.

To watch JPL will have a live stream which I will embed on Behind the Black when it goes live at about 3:30 am Eastern on the morning of April 12th.

Lava flooded mountains on Mars

1:56 pm

Lava-flooded mountains on Mars
Click for full image.

Overview map

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

12:33 pm

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

12:04 pm

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.
