Flooding from crater lakes on Mars

9:36 am

Loire Valley on Mars

According to a new paper published today, scientists estimate that flooding from crater lakes on Mars — caused by sudden breaches in the crater rims — could have created as much as 25% of the volume of the valley networks that have been identified there.

Mars’ surface hosted large lakes about 3.5 billion years ago. Some of these lakes overtopped their rims, resulting in massive floods that rapidly formed deep canyons. Similar lake breach floods occurred in the northwest United States and central Asia at the end of the last glacial period over 15,000 years ago.

“We found that at least a quarter of the total eroded volume of Martian valley networks were carved by lake breach floods. This high number is particularly striking considering that valleys formed by lake breach floods make up just 3% of Mars’ total valley length,” Morgan said. “This discrepancy is accounted for by the fact that outlet canyons are significantly deeper than other valleys. These floods would have shaped the overall Martian topography, affecting the flow paths of other valleys. Our results don’t negate the importance of precipitation-fed runoff on early Mars. On the contrary, liquid water had to be stable for long enough for lakes to fill from inlet rivers.” [emphasis mine]

The map above shows in white the Loire Valles on Mars, located at about 20 degrees south latitude in transition zone between the northern lowland plains and southern cratered highlands. The paper cites this valley as a typical example of a flood valley caused by a crater rim breach.

This research only makes the geological and climate history of Mars more puzzling. Though the geological evidence strongly suggests lakes and liquid water once existed on Mars, and this research strengthens that conclusion (as indicated by the highlighted sentence above), no model of the planet’s climate has ever satisfactorily created a situation where that was possible. Either there are factors about Mars’ ancient history we have not yet identified (likely) and don’t yet understand (very likely), or the planet’s geology was formed by processes alien to Earth and thus not yet recognized by us.

Government shutdown threatens Lucy asteroid mission

9:00 am

Government marches on! The possibility that the federal government could shut down because of the inability of Congress and the Biden administration to pass a funding bill or raise the debt limit now threatens the launch of the Lucy mission to the asteroid belt.

If no budget agreement is reached the government will shut down on October 1st. If the debt limit isn’t raised that shutdown could follow soon thereafter, even if a budget is passed.

The launch window for the mission is from October 16 to November 7, 2021. If the spacecraft does not launch in that window the science team says it will likely require a major rethinking of the entire project, as it will be difficult to find another opportunity to visit the same set of asteroids.

Right now the chances of a shutdown are very high, as the Democrats are pushing big spending bills without any negotiations with the Republicans. In answer, the Republican caucus has said that none of its members will support raising the debt limit. Without the latter any passed spending bill will soon be moot, as the debt limit will soon be reached, blocking further government spending.

Though I personally would be very saddened if Lucy was prevented from launching, that loss would be well compensated for by having the federal government out of business. The evil and corruption promoted by it far outweighs the good work done by several minor space missions.

Today’s blacklisted American: New cancel culture database lists more than 1,400 examples of censorship and blacklisting in academia

1:20 pm

Orwell's 1984
The instruction manual of today’s academia.

The new dark age of silencing: The news outlet The College Fix today released a new database it calls the Campus Cancel Culture Database, listing all the stories that it has covered in the past decade of blacklisting and censorship on college campuses.

To see the complete list, go here. They plan to update it regularly. As Jennifer Kabbany, editor of The College Fix writes,

At some point, I lost count of how many incidents [of blacklisting] we’ve documented. Earlier this year, however, we began to compile them systematically — and today The College Fix releases the Campus Cancel Culture Database. The detailed repository of information lists more than 650 successful cancellations. They include everything from statues hauled off campuses to renamed buildings to memory-holed mascots. The database also cites more than 750 attempted cancellations.

We define cancel culture as any effort by people or groups to identify someone or something as offensive or unacceptable and seek in some way to censor or punish the transgressor or item.

It includes professors who have been suspended or lost their jobs for saying or researching something unpopular, student groups attacked or barred for their conservative, pro-life or libertarian views, and guest speakers shouted down or disinvited.

Overall, the database documents the terrible state of academic thought in the United States. Across the country college administrators, teachers, and students have teamed up to silence any ideas or opinions they do not like, with the bulk of the attacks going against conservatives and the traditions and concepts of western civilization. Not only have people been fired and blackballed, even discussing openly the history of our nation has become verboten. You must either condemn the American dream as racist white supremacy, or you must shut up.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Perseverance as seen from orbit

12:00 pm

Perseverance as seen from orbit
Click for full image.

Overview map
Click for interactive map.

The science team for the high resolution camera on Mars Reconnaissance Orbiter (MRO) have snapped a picture of Perseverance at its present location in Jezero Crater.

The first image to the right, cropped to post here, shows the rover as a white dot to the right of the two long sand dunes. If you look close image, you can see the rover’s tracks near the bottom of the image.

Ingenuity is likely also in the full image, but is likely too small for MRO’s high resolution camera to pick out.

The second image is a overview map. The green dot marks the rover’s position, with the red dot Ingenuity’s present position. The dotted white line shows the route the rover has taken so far. The light brown line indicates the flight paths for all of Ingenuity’s flights. The yellow dotted line indicates the future planned route of Perseverance.

With Mars about to slip behind the Sun, communications with both rovers, Perseverance and Curiosity, as well as all the orbiters, will shortly go silent for about two weeks.

When that pause ends, the question will be where Perseverance goes next. The original plan was to retreat back along its previous path, going to the southeast before heading north past the landing site. I strongly suspect that they will instead head directly to the landing site, going to the northeast across the rough terrain, both to see something new as well as further test the rover’s ability to travel tougher ground.

They avoided that area initially because they were still in the rover’s check out period. Now that they know it works, there is no reason to avoid that ground, especially because it will be ground they have not viewed before. They could even use Ingenuity to scout it out more thoroughly.

BepiColombo about to make first of six Mercury flybys

11:16 am

The European/Japanese BepiColombo probe will make its first of six fly-bys of Mercury on October 1, 2021, as it steadily adjusts its flight path to enter orbit around the planet in 2025.

The mission is made up of two Mercury orbiters, Europe’s Mercury Planetary Orbiter and Japan’s Mio orbiter.

During the flybys it is not possible to take high-resolution imagery with the main science camera because it is shielded by the transfer module while the spacecraft is in cruise configuration. However, two of BepiColombo’s three monitoring cameras (MCAMs) will be taking photos from about five minutes after the time of close approach and up to four hours later. Because BepiColombo is arriving on the planet’s nightside, conditions are not ideal to take images directly at the closest approach, thus the closest image will be captured from a distance of about 1000 km.

The first image to be downlinked will be from about 30 minutes after closest approach, and is expected to be available for public release at around 08:00 CEST on Saturday morning. The close approach and subsequent images will be downlinked one by one during Saturday morning.

The cameras provide black-and-white snapshots in 1024 x 1024 pixel resolution, and are positioned on the Mercury Transfer Module such that they also capture the spacecraft’s solar arrays and antennas. As the spacecraft changes its orientation during the flyby, Mercury will be seen passing behind the spacecraft structural elements.

These will be the first close-up pictures of Mercury since the Messenger orbiter mission ended in 2015.

United Kingdom’s new comprehensive space strategy: develop a robust private sector

10:45 am

Map of UK space strategy

Capitalism in space: The United Kingdom yesterday released a new comprehensive space strategy that seems generally focused on encouraging the growth of a private aerospace industry.

You can read the actual strategy here [pdf].

Though most of the text is high-sounding but mostly meaningless political talk, the overall strategy is excellent. It is focused not on creating a “space program” that the British government will design and build — what had been the traditional but generally unsuccessful approach since the 1960s — but to instead find ways to encourage the private sector to achieve what it wants to do. The map to the right, taken from the strategy document, illustrates this. The focus is entirely in supporting the growth of a commercial private industry by either creating industrial centers for space manufacturing or spaceports for launching satellites.

In this context, the vagueness of the strategy’s goals makes sense. The UK government has properly concluded that it is not its place to set those goals, but to let the commercial sector do it based on where they think they can make the most profit.

All in all, this strategy bodes well for the UK’s future in space.

Blue Origin sets October 12th for next suborbital tourist flight

10:12 am

Capitalism in space: Blue Origin announced yesterday that it has scheduled October 12, 2021 for its next New Shepard suborbital tourist flight, carrying four passengers, two of which have been revealed.

The company has revealed two of the four crewmembers will be Chris Boshuizen, co-founder of Earth observation company Planet Labs, and Glen de Vries, vice chair for life sciences and healthcare at French software company Dassault Systèmes. The remaining two crewmembers will be announced in the coming days, Blue Origin said in a statement.

The NS-18 mission, the 18th flight overall for the New Shepard rocket, will lift off from Blue Origin’s Launch Site One in West Texas at 9:30 a.m. EDT (8:30 a.m. CDT or 1330 GMT) on Oct. 12. In addition to the four passengers, the flight will carry thousands of postcards from Blue Origin’s foundation, Club for the Future, which aims to inspire future generations to pursue careers in sciences, technology, engineering and mathematics (STEM).

There have been rumors that William Shatner will be one of the other passengers, but this has not yet been confirmed.

Satellite company Terran Orbital to build big satellite factory in Florida

10:06 am

Capitalism in space: The satellite company Terran Orbital announced yesterday it will build a large factory to manufacture more than a 1,000 small satellites per year.

At the Launch and Landing Facility, formerly known as the NASA Space Shuttle Landing Facility, Terran Orbital, the parent company of Tyvak and PredaSAR, plans to claim 10 hangars for what Space Florida calls “the world’s largest satellite manufacturing facility.”

“Not only will we be able to expand our production capabilities to meet the growing demand for our products, but we will also bring valuable space vehicle manufacturing opportunities and capabilities to the State of Florida, investing over $300 million in new construction and equipment,” Marc Bell, Terran Orbital co-founder and CEO said in a statement. “By the end of 2025, we’re going to create approximately 2,100 new jobs with an average wage of $84,000.”

It appears that Lockheed Martin is both a customer for these satellites as well as one of Terran Orbital investors.

Regardless, with that many smallsats in the pipeline for construction provides one explanation why investors have been flocking to finance new rocket companies.

China’s Long March 3B successfully launches satellite, which then fails

9:58 am

China’s Long March 3B rocket successfully launched a military satellite yesterday, though the satellite then had an undisclosed issue which caused it to fail.

Though the satellite failed to function immediately after launch, it appears the launch itself was successful, which based on my criteria means this launch is counted in China’s 2021 launch totals. The leaders in the 2021 launch race are thus:

34 China
23 SpaceX
15 Russia
4 Northrop Grumman

The U.S. still leads China 35 to 34 in the national rankings.

Data suggests the winds in Jupiter’s Great Red Spot are changing

2:46 pm

Changing wind speeds in Great Red Spot
Click for original image.

Data accumulated from 2009 to 2020 by the Hubble Space Telescope suggest that the outer winds in Jupiter’s Great Red Spot have speeded up by about 8%, while the winds in the spot’s inner regions have slowed.

The change in wind speeds they have measured with Hubble amount to less than 1.6 miles per hour per Earth year. “We’re talking about such a small change that if you didn’t have eleven years of Hubble data, we wouldn’t know it happened,” said Simon. “With Hubble we have the precision we need to spot a trend.” Hubble’s ongoing monitoring allows researchers to revisit and analyze its data very precisely as they keep adding to it. The smallest features Hubble can reveal in the storm are a mere 105 miles across, about twice the length of the state of Rhode Island.

“We find that the average wind speed in the Great Red Spot has been slightly increasing over the past decade,” Wong added. “We have one example where our analysis of the two-dimensional wind map found abrupt changes in 2017 when there was a major convective storm nearby.”

The graphic above shows the different wind speeds between the spot’s inner and outer regions, not the increase in speed described in this press release.

To put it mildly, these results are uncertain. We simply could be seeing the long term random fluctuations in the storm, or the change could simply be a reflection of the data’s margin of error. Moreover, since the data covers only the top layer of the Great Red Spot, it tells us nothing about the storm’s deeper regions or its more fundamental origins.

Rivulets in Martian lava

2:14 pm

Overview map

Today’s cool image is another example of scientists finding cool things hidden within distant pictures. The small white rectangle on the overview map to the right shows us where we are heading, to the severely eroded lava plains to the southwest of Mars’ largest volcano, Olympus Mons.

The white spot is about 500 miles from the caldera of Olympus Mons. In elevation it sits about 58,000 feet below that caldera, more than twice the height of Mt. Everest. Yet, despite these great distances, the material at that white rectangle was almost certainly laid down during an eruption from Olympus Mons, thus illustrating the gigantic scale of volcanic events on Mars. Because of the red planet’s light gravity, about 38% of Earth’s, not only can lava flow farther, it does so much faster.

The second image below is a wide angle photo taken by the context camera on Mars Reconnaissance Orbiter (MRO) in January, 2012, rotated, cropped, expanded, and enhanced to post here.

Today’s blacklisted American: Unvaccinated students at Penn State banned from remote classes

12:23 pm

Coming to your town in America soon!
Rounding up the unclean unvaccinated: It is coming.

They’re coming for you next: Unvaccinated students at Penn State who fail to get a COVID test for three weeks in a row are now banned from the school, including a ban from even attending remote classes.

At Penn State University, 117 students have been placed on interim suspension for failure to comply with the university’s weekly COVID-19 testing requirement.

Students at University Park who are subject to required weekly COVID-19 testing and who have missed at least three weeks of testing have been notified by Penn State that they are out of compliance with the university’s health and safety policies and have been placed on interim suspension through the Office of Student Conduct, a statement from Penn State said.

Students on interim suspension may not participate in classes, in-person or remotely; are not allowed on university property; and may not attend any Penn State-sponsored events, programs, and activities, including football games. On-campus students on interim suspension also are temporarily removed from their residence halls.

The highlighted word prove the insanity and irrationality of this policy. » Read more

ULA successfully launches Landsat 9

11:30 am

Capitalism in space: Using its Atlas-5 rocket ULA today successfully launched Landsat 9, built by Northrop Grumman.

At the time of writing, the rocket and payload are in orbit and in a 60-minute coast phrase prior to payload deployment.

This was only the third launch this year by ULA, tying them with Rocket Lab but still too few launches to make the leader board. The leaders in the 2021 launch race remains the same:

33 China
23 SpaceX
15 Russia
4 Northrop Grumman

The U.S. now leads China 35 to 33 in the national rankings. In 2020 the U.S. completed 40 launches total, the most since 1968. At the moment there are sixteen more U.S. launches scheduled for launch in 2021. If all occur as planned, that would make 51 launches, making ’21 the fifth best launch year for the U.S. ever, exceeded only by four years in the mid-1960s.

For ULA, the low number of launches so far this year continues a slow downward trend since 2014, when the company completed fourteen launches. ULA still has four launches listed for ’21, but one, the unmanned Starliner demo launch, is likely to get delayed till ’22. The dates of two other launches remain “too-be-determined”, which also makes them questionable.

China launches Earth observation satellite

8:37 am

China today successfully launched an Earth observation satellite using its smallsat Kuaizhou-1A rocket, the first launch of this quick response rocket since a failure in November 2020.
The satellite is supposedly for commercial use, but little information has been released about it and its constellation.

The leaders in the 2021 launch race:

33 China
23 SpaceX
15 Russia
4 Northrop Grumman

The U.S. still leads China 34 to 33 in the national rankings, with these numbers changing in a few hours should ULA successfully launch Landsat 9 using its Atlas-5 rocket.

Glaciers in the Martian south latitudes

1:12 pm

Glaciers in Mars' southern hemisphere
Click for full image.

Most of the glacier cool images I have posted in the past few years from the high resolution camera on Mars Reconnaissance Orbiter (MRO) have shown the obvious glacial features found in the northern hemisphere in that 2,000 mile long strip of chaos terrain at about 40 degrees latitude I dub “Glacier Country.”

Today’s glacier image to the right, cropped and reduced to post here, takes us instead to the southern hemisphere, into Hellas Basin, the death valley of Mars. The picture was taken on April 8, 2021, and in the full picture gives us a myriad of examples of glacial features. The section featured to the right focuses in on what appears to be an ice covered south facing slope, which in the southern hemisphere will get the least sunlight.

Think of the last bits of snow that refuse to melt after a big blizzard. They are always found in shadowed areas, which in the southern hemisphere would be this south-facing slope.

The overview map below shows how this location, marked by the small white rectangle, is inside Hellas Basin, at a low altitude comparable to the northern lowland plains. The feature is also a comparable latitude, 43 degrees south, to the glacier country of the north.

Today’s blacklisted American: Garden hoes banned by Facebook!

12:11 pm

Garden hoes banned by Facebook!
According to Facebook, a garden hoe apparently represents evil
and the worst of white supremacy.

Today’s blacklisted American, garden hoes, is meant more to illustrate the utter brainlessness of the blacklist culture, and why every intelligent American should refuse to bow to it in any way.

It appears that Facebook has been repeatedly flagging and then blocking posts on a gardening group because those gardeners periodically make reference to the gardening tool called a “hoe.”

A group called WNY Gardeners has been repeatedly flagged by the social network for “violating community standards,” when its more than 7,500 members discussed the long-handled bladed implement, which is spelled with an “e,” unlike the offensive term.

When one member commented “Push pull hoe!” on a post about preferred weeding tools, Facebook sent a notification that read, “We reviewed this comment and found it goes against our standards for harassment and bullying,” a moderator said.

“And so I contacted Facebook, which was useless. How do you do that?,” Elizabeth Licata said. “You know, I said this is a gardening group, a hoe is gardening tool.”

Nor has this been Facebook’s only “hoe” error. It had also been routinely flagging posts that referred to the English seaside community of Plymouth Hoe.

Facebook of course never responded to gardening group when they complained, as is usual for these inhumane big tech companies. However, when this story began appearing in the press, it told the AP that it was sorry about it, had corrected the algorithms that had caused the problems, and had assigned a real human to monitor the gardening group to make sure it is not censored for ordinary gardening discussions.

Hah! That didn’t work. The gardeners soon found themselves censored for writing about the various techniques they use for battling the Japanese beetle, a destructive pest to “flowers, trees and shrubs, fruits and vegetables, field crops and turf.” When on commenter suggested that gardeners should “Kill them all. Drown them in soapy water,” and “Japanese beetles are jerks,” the posts were blocked by Facebook.

It seems Facebook employees really don’t know how to read. Instead, they work eagerly to silence anyone for any statement they think should be silenced, without thought.

All this reminds me of the short clip below from the early 1960s cartoon show, Rocky & Bullwinkle.

News flash! Union lobbyists wants to influence Biden against non-union SpaceX

9:41 am

In the past two days probably a dozen of my readers have sent me a link to this story at the Washington Examiner,
The Anti-SpaceX lobbying campaign casts new light on Elon Musk’s Biden beef.

The story reveals some private emails between a union lobbyist and a vice president at ULA, outlining their mutual effort to discredit Elon Musk and SpaceX because of its long term success in preventing its workforce from unionizing.

Everyone who has sent me this story somehow thinks it reveals a major breaking story.

I think this story is a tempest in a teapot. It reveals nothing newsworthy. All it shows is that a union lobbyist is trying to influence the Biden administration against SpaceX, a decidedly non-union company. Why should these actions surprise anyone? Unions always go after non-union companies, and they often do it by exerting their political clout.

Nor should be we surprised that one of SpaceX’s biggest competitors is partnering with the union in this effort. There is nothing newsworthy about this. Competitors compete, and that competition can sometimes be quite cut throat.

Furthermore, nothing in these emails appears illegal. The lobbyist’s claims against SpaceX are spurious and shallow, but so what? Unions have the right to lobby politicians, and they have the freedom to make whatever arguments they want, even if those arguments are silly or false.

Finally, to think it is a news story that Biden might be receptive to union lobbyists is kind of silly. Biden is a modern Democrat. In almost all matters he is going to genuflect to the unions. I don’t need to read the private emails of a union lobbyist to find this out.

However, the evidence in the past ten months shows that this lobbying effort has so far been incredibly ineffective. While I certainly do not trust the Democrats running the Biden administration, and fully expect them to take actions eventually to squelch private enterprise, this White House’s actions regarding space has so far generally continued the capitalist policies begun during the Trump administration. Note too that these are the same policies first begun at the end of the Bush Jr. administration, and encouraged strongly throughout the Obama administration. It certainly appears that — in space at least — the Democrats are as much for capitalism as the Republicans.

And these emails have apparently done nothing to change that. Thus, there is no news here.

Northrop Grumman says six customers have bought missions using its upgraded orbital repair robot

9:04 am

Capitalism in space:A Northrop Grumman official has revealed that it already has six customers willing to buy missions using its upgraded orbital repair robot to fix orbiting satellites that are presently defunct due to lack of fuel.

Unlike the company’s first robotic repair satellites, dubbed Mission Extension Vehicles (MEV), the Mission Robotic Vehicle (MRV) for these new contracts will not dock directly to the satellite, but use a robot arm to attach an extension pod to each.

The primary commercial mission of the MRV is to install small propulsion devices known as mission extension pods. One of these units is inserted in the back of a client satellite propulsion system, adding six years of life to most geostationary satellites, he said.

The six customers have signed term sheets for seven mission extension pods, Anderson said. Once contracts are firmed up the company will be able to disclose their names.

The first MRV launch in 2024 will carry three pods. “With these six customers, the MRV manifest is currently filled through mid-2026,” he said. The MRV is expected to have a 10-year service life.

This MRV system is far more cost effective than the MEV, since the latter can only repair one satellite, while the former can fix several with a single launch.

Both Northrop Grumman and Astroscale (see my previous post) are demonstrating the emergence of a new cottage satellite industry, the repair of old satellites and the removal of space junk, all for profit.

Rocket Lab wins contract to launch space junk removal satellite

8:49 am

Capitalism in space: Rocket Lab announced this week that it has won a launch contract from the Japanese-based company Astroscale to launch its first attempt to rendezvous with a piece of space junk — an abandoned upper stage from a Japanese launch — in order to grab and de-orbit it.

Rocket Lab announced Sept. 21 that it won a contract from Astroscale for the launch of its Active Debris Removal by Astroscale-Japan (ADRAS-J) spacecraft. A Rocket Lab Electron will launch ADRAS-J from its Launch Complex 1 in New Zealand in 2023.

ADRAS-J will rendezvous with and inspect an upper stage left in orbit by a Japanese launch. The Japanese space agency JAXA awarded Tokyo-based Astroscale a contract in 2020 for the mission as part of its two-phase Commercial Removal of Debris Demonstration project.

The first phase of this demonstration project involved Astroscale’s current test satellite, which is presently testing capture techniques of space junk using magnets.

It appears Rocket Lab got the contract because it can place this smallsat in the precise orbit it needs, and can do it for far less than any other launch company in operation at present.

InSight detects the three more large quakes on Mars, the most powerful measured so far

8:40 am

In the past month InSight’s seismometer has detected the three most powerful earthquakes so far measured on Mars, with one located in a region where no quakes had as yet been seen.

InSight spotted 4.2- and 4.1-magnitude temblors on Aug. 25, then picked up another roughly 4.2-magnitude quake on Sept. 18 that lasted for nearly 90 minutes, NASA officials announced on Wednesday (Sept. 22).

The previous record holder, which InSight measured in 2019, clocked in at magnitude 3.7 — about five times less powerful than a 4.2-magnitude quake.

At this time scientists have only been able to roughly pinpoint the location of the two August quakes, with the 4.1 quake occurring about 575 miles away, putting it in the volcanic plains where InSight sits and closer than the location of most of the previous large quakes near the long surface fissures dubbed Cerberus Fossae 1,000 miles away.

The August 4.2 quake’s is even more interesting, as its location is the farthest away of any so far detected, at an estimated distance of 5,280 miles away. The scientists presently suspect but have not yet confirmed that it may be located in the western end of Valles Marineris, Mars’ largest canyon.

The lander itself continues to fight a loss of power due to the amount of dust on its solar panels, forcing the science team to shut down practically all its other instruments so that the seismometer could continue operating.

Anyone who has taken even a single glance at a map of Mars cannot help but recognize that the red planet was once engulfed with repeated gigantic volcanic eruptions able to build numerous volcanoes larger than anything seen anywhere else in the solar system.

The cool image to the right, rotated, cropped, and enlarged to post here, provides a clue into those past eruptions, now thought to have been active for more than several billion years, with the most recent large activity ending several tens of millions of years ago. The photo was taken on May 7, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows just one tiny portion of the vast Medusae Fossae Formation, the largest thick volcanic ash deposit on Mars, about the size of India and what scientists think is the source of most of the planet’s dust.

What makes this picture interesting are the dark layers in the lower hollows. They indicate that this deposit was placed down in multiple eruptions, some of which produced material that appears dark blue in MRO images, and suggest that eruption was different than previous and subsequent eruptions.

The white cross on the overview map below notes the location of this picture in the Medusae Fossae Formation.

Today’s blacklisted Americans: Republicans blacklisted 53 to 1 over Democrats on social media

12:05 pm

Silenced by Twitter, Facebook, YouTube, and Google
Republicans: Routinely silenced by Twitter, Facebook, and YouTube.

Blacklists are back and the Democrats have got ’em: According to a review of the actions of the big social media companies against politicians, the Media Research Center has found that Republicans are censored at a rate 53 times more than Democrats on social media.

The attacks on Facebook, Twitter, YouTube, Google, Instagram, and others have been against both standing Republican members of Congress as well as Republican candidates running for office, with further evidence showing that Facebook very specifically has been favoring Democratic incumbents.

Nor have the top managers and owners of these social media companies been able to counter this data.

Fired flight director accuses Virgin Galactic of lying about problems on July suborbital flight

9:19 am

A former Virgin Galactic flight director, who was relieved of his duties just before the company’s July suborbital flight that carried Richard Branson and then fired shortly thereafter, has accused Virgin Galactic of misleading the public in its statements about the problems that occurred during that flight.

Virgin Galactic has claimed that the high winds forced the spacecraft away from its planned flight path.

Mark Stucky, who Virgin Galactic fired eight days after Branson’s flight, said his former employer put out an inaccurate statement about why VSS Unity flew unauthorized into Class A airspace for 1 minute 41 seconds during its descent. Class A airspace is primarily used by airlines, cargo operators and higher performance aircraft.

“The most misleading statement today was @virgingalactic’s,” Stucky tweeted. “The facts are the pilots failed to trim to achieve the proper pitch rate, the winds were well within limits, they did nothing of substance to address the trajectory error, & entered Class A airspace without authorization.”

There is no way to know if Stucky’s accusation is correct. We might be seeing a bit of personal anger on his part considering his firing. At the same time, the FAA’s statement about this issue made no mention of winds, which suggests the Virgin Galactic statement might not be true.

Regardless, Virgin Galactic’s track record in matters of safety has not been stellar. The company needs to quickly resolve these issues or they will become a lingering sore that will damage sales for future suborbital flights.

Wuhan panic continues to shut down India’s space agency

9:08 am

While most private companies and many nations, such as China and Russia, have been launching continuously since the advent of the coronavirus panic last year, India’s space agency ISRO continues to be shut down, completing few launches with a story today suggesting that the three remaining planned launches for 2021 will likely be delayed until next year.

There have only been two launches this year – the purely commercial PSLV C-51 launch in February carrying Brazil’s earth observation satellite Amazonia-1 and the GSLV-F10 mission in August carrying an Indian earth observation satellite EOS-03 that failed.

To be sure, the space agency has plans for three more missions before the end of the year, including the first development flight of the SSLV [Small Satellite Launch Vehicle]. The other two will use India’s workhorse PSLV to launch two earth observation satellites EOS-04 and EOS-06.

“The three planned missions appear unlikely this year,” a senior scientist at the agency said on condition of anonymity.

Worse, before the year began ISRO had reduced its targeted number of missions for ’21 from 16 to 5.

The article makes believe the epidemic has shut down other programs, such as Artemis, in the same way, but that is false. NASA’s Artemis program might have lost a few months in ’20 due to the agency’s panic over COVID, but since then it has been moving as fast as it can, considering the cumbersome nature of its engineering. Even Rocket Lab, which has been badly hampered by New Zealand draconian Wuhan rules, has managed to launch eleven times since January 2020, compared to the four launches attempted by India during that same time.

Whatever has caused the shut down at ISRO, it really hasn’t been the epidemic. Something about the agency’s management and its bureaucratic culture has prevented them from resuming flights. And as they remained stalled, the private commercial companies in the U.S. and China are grabbing their customers.
