Residue ice in southern mid-latitude Martian crater?

Residue ice in the southern mid-latitudes 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 April 10, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows an unnamed 1.2-mile-wide crater at about 35 degrees south latitude with what appears to be residual glacial ice hugging its north interior wall.

As this is in the southern hemisphere, the ground immediately below the south-facing interior wall of the crater is going to be in shadow the most, and thus it will also be the place where any surface or near-surface ice will survive the longest. In this case it appears that from the bumpy nature of that residual ice it has also been sublimating away. Within it however remains the faint hint of multiple layers, suggesting about a dozen past climate cycles with each new cycle producing a new but smaller layer with less ice.

The material in the southern half of the crater floor appears to be dust formed into ripple dunes.

Vikram finds temperatures of lunar soil varies significantly, depending on depth

9:17 am

Temperature range of soil at Vikram landing site

Based on data from one of the instruments on India’s lunar lander Vikram, scientists have found that the temperatures of the lunar soil at the landing site vary significantly, depending on depth. The temperature dropped from 55 degrees Celsuis to -10 degrees Celsuis when going from about 10 millimeters above the surface to about 82 millimeters below the surface, as shown in the graph to the right.

That’s equivalent from going from a summer day in Death Valley of 131 degrees Fahrenheit to a winter day in Minnesota of 14 degrees Fahrenheit, in a distance of only about 3.5 inches. While it was expected that there would a temperature drop, it appears the quick temperature drop just below the surface was faster than expected.

JAXA scrubs launch of X-Ray telescope & SLIM lunar lander due to high winds

8:57 am

SLIM's landing zone
Click for interactive map.

Because of high winds, Japan’s space agency JAXA yesterday scrubbed the last launch of its H2A rocket, carrying the XRISM X-Ray telescope and the SLIM lunar lander.

A nice description of both payloads can be found here. XRISM is a simplified reflight of the Hitomi X-Ray telescope that failed immediately after launch in 2016.

Though SLIM carries a camera and two secondary payloads, both designed to hop along on the surface and obtain some data, its main mission is engineering, testing whether a robotic spacecraft can achieve a precision landing with a target zone of 100 meters, or 310 feet. The map to the right shows SLIM’s landing site, with the white dot in the close-up inset a rough approximation of that entire target zone. If successful this technology will make it possible to put unmanned planetary probes in places previously thought too dangerous or rough.

All three craft are designed to operate for only about fourteen days, during the daylight hours of the 28-Earth-day-long lunar day.

Update on ESA’s much delayed Space Rider X-37B copy

10:34 am

Link here. Space Rider is essentially aiming to be another re-usable mini-shuttle like the X-37B and the unnamed classified version from China. While all three are government-owned and government-run, the X-37B and China’s both were built expressly to do military classified missions. There has been no effort in either case to make them available for commercial flights.

The European Space Agency (ESA) however is developing Space Rider instead for commercial customers. It also appears the government-owned and government-run nature of Space Rider is one of the main reasons it will not fly its maiden mission this year, and won’t fly until late 2025, at the earliest.

“As an outcome of the previous ministerial council of 2019, the Space Rider received quite significant financial support to cope with Phase C and D activities. However, the participating states contributed in a way that was not possible — due to the need to comply with the Geo-return mechanism — to keep the industrial consortium as it was operating up to that moment [end-2019],” Galli said.

ESA’s Geo-return mechanism was established to boost fairness among member states, ensuring that the nations that invest in the agency will generate a “fair return.” In a nutshell, participating states in an optional development program should receive industrial contracts in a proportional way with respect to their contribution to that program to ensure that money invested benefits the countries that actually contributed to that program. That is to say for example, if you put 30% of the funds into the program, you are expected to receive as close as possible to industrial contracts accounting for 30% of the overall program.

As the program must abide by the Geo-return mechanism, Galli explained that the initial consortium involved was required to significantly be rebuilt “in compliance with the available funds and their member state relevant origin. … This caused first a not negligible delay in setting up the new industrial consortium… that was finally concluded only in late 2020 with the signature of the new contract with the prime contractors. And then, a so-called bridging design phase was needed on the subsystems affected by the change of industrial supplier, resulting in a longer-than-expected completion of the design phase.

In other words, Space Rider can’t just sell payload space to anyone. Only private businesses in those nations who help finance it can bid, and the customers don’t match well with the ESA’s nations that had been doling up the money. The consequence apparently has been a lot of complex negotiations and jury-rigging to make the two match, all of which has nothing to do with producing a viable product that makes money.

Reality strikes: Democrats in Democratically-controlled cities complain about the consequences of Democratic Party policies

1:34 pm

The Democratic Party, always failing but always voted for
The Democratic Party, though always failing it remains
the only party the voters in these cities can support

You get what you vote for: The utter disaster of the Marxist policies of the modern radical Democratic Party are now coming home to roost in numerous cities across America, making them all increasingly “unlivable” in ways that are savage, violent, and devastating. Crime is up, shoplifting is now a sports event, and murderers go free while local prosecutors indict ordinary citizens for simply defending themselves.

These facts are not news however. Since the 1960s Democratic Party policies have routinely done damage to the livability of American cities. What makes this collapse in civilization now even more significant however is who is noticing, as shown by three recent articles in the past week.

Let’s start with Minneapolis, where numerous videos document a formerly pleasant midwest city that has now become a hellhole.

SpaceX completes successful 6-second static fire test of Superheavy

11:28 am

screen capture during static fire test
Screen capture during static fire test

SpaceX today successfully completed a full 5-second static fire test of all 33 Superheavy Raptor-2 engines as well as the deluge system of the launchpad at Boca Chica.

The link goes to the live stream, which is still on-going. The static fire test occurs at about 42 minutes, if you wish to see it.

According to the narrators of the live stream, Elon Musk tweeted that the static fire was a success. It certainly appeared to go for the full five seconds, and it certainly appeared more robust than the previous test. We will have to wait however for confirmation that all 33 engines fired as planned.

The company clearly appears just about ready to do an orbital test flight. Too bad the Biden administration still stands in the way. There is yet no word on when the FAA will approve a launch license, and the decision of the Justice Department yesterday to file a bogus discrimination lawsuit against SpaceX strongly suggests the White House is working hard to figure out ways to squelch this private effort by an American citizen and his company.

Flow channels on Mars

11:13 am

Flow channels 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 May 13, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists call a “channel and depression”, though to my eye everything looks like flow channels, descending to the east.

The drop from the narrow northern channel to wider southern channel is about 200 feet, with the small crater on the left sitting about halfway between. To our Earthbound eyes, something clearly flowed downhill from that northern channel into the wider channel. What we don’t know now is what the material was that did the flowing?

Was it liquid water? Glaciers? The overview map below provides some context, though it doesn’t actually provide an answer.

Both Vikram and Pragyan functioning as planned on the Moon

9:29 am

Pragyan on the Moon
Click to see full movie.

According to tweets from India’s space agency ISRO, both the Vikram lander and the Pragyan rover are functioning as planned on the lunar surface, with the rover successfully activating its two science instruments.

The image to the right, taken by Vikram, shows the rover as it completed its roll down the ramp onto the lunar surface. This is a screen capture from a movie showing that roll down, which you can see by clicking on the picture. Since then it has moved another 26 feet from the lander.

I must add once again that Vikram did not land “on the south pole”, as too many so-called news organizations have been falsely claiming. It landed at about 69 degrees south latitude, quite a distance from that pole, in a flat region with no permanently shadowed craters. It is not specifically looking for water, though its instruments might help explain the orbital data that suggests there are areas on the surface of the Moon where hydrogen is somehow present.

If so many news outlets can’t seem to get these very basic facts about this mission correct, one must ask what else do they get wrong routinely? I don’t ask, because I always assume their information is wrong, check it constantly, and find repeatedly that they get numerous basic facts incorrect, especially when it comes to reporting on politics.

China launches remote sensing satellite using rocket from pseudo-company

9:00 am

The Chinese pseudo-company Galactic Energy completed another successful orbital launch today, using its Ceres-1 rocket solid-fueled rocket carrying a remote sensing satellite and lifting off from the Jiuquan spaceport in the northwest interior of China.

As with the pseudo-company’s previous launch, the state-run press made no mention of the company in its reporting, underlining the fact that it really is simply another government-controlled entity that simply adds private investment and the profit-motive to its operations.

No word on where the rocket’s lower stages crashed within China.

The leaders in the 2023 launch race:

57 SpaceX
37 China
12 Russia
7 Rocket Lab

In the national rankings, American private enterprise still leads China in successful launches 66 to 37. It also leads the entire world combined, 66 to 60, while SpaceX by itself now trails the rest of the world (excluding American companies) 57 to 60 in successful launches.

  • Perseverance science team touts rover’s 19th core sample

    • If you listen closely to the two scientists in the video, they really can only guess about much of this geology, since Perseverance does not have the same geological capabilites as Curiosity. They can make some superficial analysis of the rocks, but the more detailed work will have to wait until those core samples are returned to Earth. Curiosity however can not only drill, but it has equipment to analyze those drill samples itself, there. While Curiosity can’t do what an Earth lab would do, it does it now. With Perseverance we will have to wait a decade or more to get to the samples.

Today’s blacklisted American: Real estate company fires a mother for expressing her opinions

Janet Roberson and her family
Janet Roberson and her family

They’re coming for you next: A California mother of three, Janet Roberson, was fired only days after she stood up at her local school board and objected to the queer curriculum the board was forcing on young children. This is what she had said:

Janet Roberson spoke at a Benicia Unified School District (BUSD) meeting on April 20, where she expressed concerns about the district’s sexual education curriculum that she said taught “gender confusion, not gender clarification” because it told 10-year-old students they could choose their own gender and receive puberty blockers. She said teaching “vulnerable children that lifetime dependence on medical care is a viable option is completely unacceptable and evil.”

“Children are being asked to identify their pronouns and this is now part of the ten-year-old curriculum,” Roberson said of the curriculum. “This forces a gender discussion beyond the scope of the state requirements and complicates an already overburdened classroom environment.”

Big mountains everywhere inside Valles Marineris

11:45 am

Big mountains in Valles Marineris
Click for original image.

While the giant canyon Valles Marineris on Mars is known best as the biggest known canyon in the solar system — large enough to cover the continental United States several times over — that size tends to diminish the mountainous nature of its interior. Today’s cool image attempts once again (see for example these earlier posts here, here, here, here, and here) to illustrate that stupendous and mountainous nature.

The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on May 15, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The goal of the picture was to get a better view of the numerous layers of this terraced cliff wall. What I see, however from my tourist’s perspective, is a steep wall that descends almost 4,500 feet from the high to the low point in just over three miles. This is as steep if not steeper than the walls of the Grand Canyon.

Biden’s Justice Department sues SpaceX

9:51 am

The corrupt and very partisan Justice Department of the Biden administration today sued SpaceX for discriminating against refugees and illegal immigrants because it restricts hiring to “U.S. citizens and lawful permanent residents.”

The lawsuit states SpaceX “failed to fairly consider” and “refused to hire” the asylees and refugees who ended up applying anyway. It also alleges that SpaceX “wrongly claimed” that the US’s export control laws allowed it to only hire US citizens and lawful residents. Additionally, the DOJ claims SpaceX hired “only” US citizens and green card holders from September 2018 to September 2020.

“Our investigation found that SpaceX failed to fairly consider or hire asylees and refugees because of their citizenship status and imposed what amounted to a ban on their hire regardless of their qualification, in violation of federal law,” Kristen Clarke, the assistant attorney general of the DOJ’s Civil Rights Division, says in a statement.

Justice is demanding compensation and back pay for anyone “deterred or denied employment”, as well as civil penalties.

This suit is utter garbage and puts SpaceX between a rock and a hard place. I guarantee if SpaceX had hired any illegal or refugee who was not yet a legal citizen, Biden’s State Department would have immediately sued it for violating other laws relating to ITAR (the export control laws mentioned) which try to prevent the theft of technology by foreign powers.

The Biden administration considers Elon Musk an opponent, and since it is now moving to indict and even imprison all political opposition, it is no surprise it is beginning to use lawfare against him. As I have written repeatedly, it has almost certainly pressured the FAA to slow walk any launch license approvals for SpaceX’s Starship/Superheavy. This lawsuit today simply provides further evidence that my prediction will be right that the next orbital test flight of that rocket will be delayed months.

North Korea fails again to get a military reconnaissance satellite into orbit

9:33 am

According to a report in North Korea’s state run press, a launch attempt of its new rocket Chollima-1 rocket failed to reach orbit at dawn today, its payload of a classified military reconnaissance satellite falling into the ocean.

The Korean Central News Agency (KCNA) in Pyongyang reported that the National Aerospace Development Administration launched the new Chollima-1 rocket “at dawn” August 24 from the Sohae Satellite Launch Center. The first and second stages worked as planned, but “the launch failed due to an error in the emergency blasting system during the third stage flight” according to KCNA.

South Korea’s Yonhap news agency identified the satellite as Malligyong-1, a military reconnaissance satellite and reported the launch time as 3:50 am local time (2:50 pm August 23 EDT).

The flight path can be found here. An earlier attempt in May failed also, but the cause was not specified. South Korea did recover the first stage and satellite from the May failure, claiming later the satellite had “no military utility.”

I expect South Korea to once again attempt recovery operations, but because the rocket traveled farther I also expect the chances of any recovery of material to be more unlikely.

India’s Pragyan rover has successfully been deployed on the lunar surface

9:23 am


Click for interactive map.

According to a tweet from India’s space agency ISRO late yesterday, the Pragyan rover has successfully rolled down its ramp and is now deployed on the lunar surface.

No further updates have yet been released. According to ISRO’s mission webpage the instruments on both Vikram and Pragyan are as follows:

Lander payloads: Chandra’s Surface Thermophysical Experiment (ChaSTE) to measure the thermal conductivity and temperature; Instrument for Lunar Seismic Activity (ILSA) for measuring the seismicity around the landing site; Langmuir Probe (LP) to estimate the plasma density and its variations. A passive Laser Retroreflector Array from NASA is accommodated for lunar laser ranging studies.

Rover payloads: Alpha Particle X-ray Spectrometer (APXS) and Laser Induced Breakdown Spectroscope (LIBS) for deriving the elemental composition in the vicinity of landing site.

Pragyan’s two spectroscopes are likely similar to instruments on Curiosity and Perseverance on Mars, and allows some good surface analysis. Without a scoop however there will be no analysis of anything below the ground, unless the rover can upend a rock using its wheels.

Rocket Lab launches a satellite reusing one rocket engine from previous flight

9:20 pm

Rocket Lab not only successfully launched a satellite tonight (August 24 in New Zealand), its first stage used a rocket engine that had flown previously.

In addition, the first stage was designed to be reused, and was quickly recovered after it splashed down in the Pacific. The plan is to refly either this or another recovered first stage in one of the company’s upcoming launches in the coming months, making Rocket Lab the second private company in the world, after SpaceX, to reuse a first stage.

The leaders in the 2023 launch race:

57 SpaceX
36 China
12 Russia
7 Rocket Lab

In the national rankings, American private enterprise now leads China in successful launches 66 to 36. It also leads the entire world combined, 66 to 59. SpaceX by itself still trails the rest of the world (excluding American companies) 57 to 59 in successful launches.

Blacklisted 12-year-old appeals lower court decision saying he has no free speech rights

1:18 pm

The shirt that offended teachers at Nichols Middle School
Liam Morrison, wearing the evil shirt that he wore the
second time teachers at Nichols Middle School sent
him home.

Bring a gun to a knife fight: Today’s blacklist story is a follow-up from May. At that time 12-year-old Liam Morrison had discovered that his school, Nichols Middle School in Middleborough, Massachusetts, would not allow him to wear a shirt that said “There are only two genders,” and when he tried to return to school with a shirt that instead said “There are only censored genders,” he was sent home again.

Morrison and his parents enlisted the non-profit legal firm Alliance Defending Freedom to sue for his first amendment rights, but in June Judge Indira Talwani (appointed by Barack Obama) ruled that Morrison had no right to the first amendment, that his shirt infringed other “students’ rights to be ‘secure and to be let alone’ during the school day.”

You can read her convoluted ruling here [pdf], which required her to ignore numerous previous Supreme Court rulings that have specifically protected student speech exactly like Morrison’s. Moreover, her decision is also based on the fraudulent premise that people are supposed to be protected from speech that offends them. If people have the power to silence any speech because it hurts their feelings then no free speech exists at all. We will live in a totalitarian nightmare worse than anything dreamed up by George Orwell.

Where the Martian landscape begins to dry out

Where Mars begins to dry out
Click for original image.

Today’s cool image to the right, cropped, reduced, and sharpened to post here, provides us a glimpse at the lower mid-latitudes of Mars where the terrain is beginning to dry out as we move south. The picture was taken on April 29, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows what the scientists label “large linear features.”

The main north-south ridge is only about 20-25 feet high, and its meandering nature (which can be seen more clearly in the full image) suggests it is possibly an inverted channel, formed when the bed of a former canyon gets compressed by the water or ice that flows through it, and when the surrounding terrain gets eroded away that channel bed becomes a ridge.

These ridges however could also possibly be volcanic dikes, where magma had pushed up through fractures and faults to form these more resistant ridges.

First mission in Isaacman’s private space program delayed again

9:56 am

The first mission in the Polaris space program of manned flights by billionaire Jared Isaacman, using SpaceX’s manned spacecraft and rockets, has now been delayed until early in 2024.

Isaacman, in the podcast interview, suggested the delays were linked to the development of a new spacesuit required for a spacewalk, the first by a private astronaut mission, planned for Polaris Dawn. “We’ve had a little bit more free time this summer than we probably would have expected,” he said, which he attributed to the timing of spacesuit development and training. That effort “doesn’t always sync up, so we’ve had a little more free time with family and work this summer.”

That new suit, billed as the first new spacesuit developed in the United States in four decades, is critical to future human activities on moon and Mars, he argued. “We’re going to need spacesuits that don’t cost hundreds of millions of dollars in order to do that. We’re pretty excited because the suit that we are testing out, the evolution of it someday could be very well worn by people that are walking on the moon or Mars.”

This mission, dubbed Polaris Dawn, will use a Falcon 9 and one of SpaceX’s fleet of four manned Dragon capsules to spend several days in Earth orbit while conducting that first private spacewalk. Isaacman’s entire Polaris program includes two more manned missions,the second possibly aimed at raising and even doing maintenance on the Hubble Space Telescope, and the third using Starship to go around the Moon.

Isaacman has already flown one private mission in space, in 2021, dubbed Inspiration4. It flew for three days in orbit, carrying four passengers, including Isaacman himself. Since it did not dock with ISS, it was an entirely private manned mission, with no significant government involvement.

Space junk that ESA demo mission intends to de-orbit as been struck by another piece of space junk

9:44 am

In a strange bit of irony, an abandoned payload adapter from a mission launched a decade ago that a European Space Agency (ESA) mission was planning on capturing and de-orbiting has been hit by another piece of space junk, creating additional bits debris around it.

The adapter is a conical-shaped leftover, roughly 250 pounds (113 kg) in mass, from a 2013 Vega launch that sent a small fleet of satellites into orbit. Space tracking systems found new objects nearby the adapter, which ESA learned about on Aug. 10. The objects are likely space debris from a “hypervelocity impact of a small, untracked object” that smacked into the payload adapter, the agency said. We may never know if the crashing object was natural or artificial, given it didn’t appear in tracking systems.

The ESA mission, dubbed Clearspace-1, intends to launch in 2026 and use four grappling arms to grasp the payload adapter, after which both shall be sent to burn up in the atmosphere. Its goal is to demonstrate technology for removing space junk. This event, creating extra debris pieces around the payload adaptor, puts a kink on that mission while also underlining the need for such technology.

Mission engineers now have three years to figure out what, if anything, they need to do to deal with the extra debris. The good news so far is that it appears the payload adapter remains intact, its orbit has not changed, and the surrounding debris appears small enough to pose “negligible” risk.

India successfully lands Vikram on the Moon

9:10 am


Click for interactive map.

India this morning successfully placed its Vikram lander, carrying its Pragyan rover, on the surface of the Moon in the high southern latitudes.

I have embedded the live stream below, cued to just before landing.

The next challenge is getting Pragyan to roll off Vikram, and spend the next two weeks exploring the nearby terrain. The mission of both it and Vikram is only planned to last through the daylight portion of the 28-day-long lunar day, so it is not expected for either to survive the lunar night. Both will make observations, but the main purpose of this mission has already been accomplished, demonstrating that India has the technological capability to land an unmanned spacecraft on another planet. That the landing was in the high southern latitudes added one extra challenge to the mission.
