A Mars mesa carved by floods and lava?

1:29 pm

Overview map of Kasei Valles

With today’s cool image we once again start our journey from afar, and zoom in. The overview map to the right focuses in on the thousand-mile-long Kasei Valley on Mars.

The blue area is where scientists postulate a lake once existed, held there by an ice dam (indicated by the white line). At some point that ice dam burst, releasing the water in a catastrophic flood that created the braided flow features that continue down Kasei Valles to the northern lowland plain of Chryse Planitia.

The black area marks a giant lava flow that scientists believe came later, following the already carved stream channels for a distance of 1,000 miles, traveling at speeds of 10 to 45 miles per hour.

The red dot near the Kasei Valles resurgence is today’s cool image.

Today’s blacklisted American: Suspended for refusing to exempt black students from finals, UCLA professor sues

11:49 am

King's dream banned at UCLA
King’s dream of equal treatment for all
called racist at UCLA

They’re coming for you next: Gordon Klein, an accounting professor at UCLA for 39 years, has sued that university’s Anderson School of Management and its administrators for suspending him for three weeks in June because he refused to favor black students in grading or exempt them from final exams.

Prof. Klein’s alleged offense was that he insisted on treating black students equally. He refused a request by a white student to allow black students preferential treatment on final exams. Because such a racial preference would violate UCLA’s anti-discrimination policies (and maybe even the law), Klein refused. Students then launched a defamatory campaign against Prof. Klein, and the cowards who run UCLA’s Anderson School capitulated, denouncing and suspending Klein. He eventually was reinstated — because he did absolutely nothing wrong — but not before his reputation and career were severely damaged.

..Prof. Klein has just filed a lawsuit in California state court, and among the things he wants, is for UCLA administrators to be held personally liable. [emphasis mine]

During his suspension Klein was also threatened with violence, requiring an increased police presence at his home to protect him.

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.

Hazygreyart – All SpaceX Launches From KSC in 4 Minutes 20 Seconds

6:01 pm

An evening pause: The video covers all launches through the beginning of this summer, when SpaceX paused for two months. Watch how the pace steadily picks up. If you watch closely you can also see boosters landing in the background.

I lot of people like to talk. Elon Musk likes to do. I’ll take his approach any day.

The song is Audionautix by Opus One.

Hat tip Martin Kaselis.

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.

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.
