Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on February 17, 2012 by the wide-view context camera on Mars Reconnaissance Orbiter (MRO). It shows a section of the northern lowland plains of Mars, latitude 31 degrees north, where several very inexplicable and isolated ridges can be seen.

One ridge meanders mostly in a north-south direction, while a second instead meanders east-west. The shape of both says that neither has anything to do with any past impact crater. In fact, their random snakelike shape doesn’t really fit any obvious explanation. For example, they do not fit the look of the many fossil rivers found on Mars, where the hardened and dry riverbed channel resists erosion and becomes a ridge when the surrounding terrain erodes away.

What geological process caused them? In the decade since this photo was taken the scientists who use MRO have only been able to snap a handful of high resolution images of these ridges. The image below is the most recent, covering the area in the white rectangle above.

Today’s blacklisted American: University of Arizona gives free tuition to American Indians; All other races must pay

12:01 pm

Academia: dedicated to segregation!
University of Arizona: dedicated to the new segregation!

“Segregation today, segregation tomorrow, segregation forever!” The University of Arizona has begun a new racist policy whereby anyone who is a member of one of 22 American Indian tribes that exist in the state will be excused from paying any tuition or fees while studying on campus.

Beginning in the fall, new and continuing full-time, degree-seeking, in-state undergraduates will be eligible for the Arizona Native Scholars Grant, the first program of its kind in Arizona. The program will be administered by UArizona Enrollment Management.

“Serving Arizona’s Native American tribes and tribal students is a crucial part of the University of Arizona’s land-grant mission, and the Arizona Native Scholars Grant program is another important step among many to do that,” said University of Arizona President Robert C. Robbins. “I am so proud that that this university has found a way to help hundreds of students more easily access and complete a college education, and I look forward to finding ways to take these efforts even further.”

To be eligible, students must complete the Free Application for Federal Student Aid, or FAFSA, and provide tribal identification. Native American tribes’ federal legal status allows universities to administer scholarships and grants to tribal members.

More than 400 students enrolled at UArizona last year meet the criteria for the new program.

Let me translate what UA president Robert C. Robbins is really saying:

Kepler signs up D-Orbit’s orbital tug for its next two satellites

9:56 am

Capitalism in space: The Canadian company Kepler — which already has nineteen satellites in orbit providing data communications — will use the orbital tug developed by the start-up D-Orbit and dubbed ION on its next two satellites.

After separating from the launch vehicle, D-Orbit intends to use ION to drop Kepler’s satellites off at a sun-synchronous orbit (SSO) between 500 and 600 kilometers. Each satellite is the size of six cubesats, a standard smallsat form factor measuring 10 centimeters on each side.

Kepler previously had a deal to use Momentus’s Vigoride tug, but delays and further in-orbit technical problems with that tug has apparently forced it to switch to D-Orbit.

New research confirms long term bone loss during long missions in weightlessness

9:46 am

According to new research done on ISS, scientists have confirmed what Soviet-era scientists had learned back in the 20th century, that long term bone loss during long missions in weightlessness can take many months to recover once back on Earth.

The bone density lost by astronauts was equivalent to how much they would shed in several decades if they were back on Earth, said study co-author Dr Steven Boyd, of Canada’s University of Calgary and director of the McCaig Institute for Bone and Joint Health.

The researchers found that the shinbone density of nine of the astronauts had not fully recovered after a year on Earth – and they were still lacking about a decade’s worth of bone mass. The astronauts who went on the longest missions, which ranged from four to seven months on the ISS, were the slowest to recover. “The longer you spend in space, the more bone you lose,” Boyd said.

The study also confirmed that some exercises in space helped to mitigate the bone loss, which ranged from 1% to 2% per month. No exercises prevented it however.

For missions to Mars, the bone loss appears less of an issue than the loss of muscle strength. Even with extensive bone loss after six months to a year in space astronauts do not notice this loss when returning to Earth gravity. They will certainly not notice it on Mars, with a gravity field 39% that of Earth’s.

More concerning is the loss of muscle strength during long missions in weightlessness. After six months to a year in weightlessness astronauts struggle on Earth to walk after first landing. This is why they are helped immediately placed to chairs upon return. On Mars no such help will be available.

OneWeb signs up startup rocket company Relativity for future satellite launches

9:34 am

Capitalism in space: The rocket startup Relativity, which hopes to complete its first test launch of its small Terran-1 rocket before the end of the year, yesterday announced that it has won a launch contract with OneWeb to use its larger but not-yet-ready-for-launch Terran-R rocket to place future OneWeb satellites into orbit.

Under the agreement, Relativity will launch OneWeb’s low Earth orbit (LEO) satellites on Terran-R, the first fully reusable and entirely 3D printed rocket, starting in 2025. These launches will support OneWeb’s deployment of its Gen 2 satellite network, which will add capacity and fresh capabilities to build upon the initial constellation of 648 satellites the company is currently building out.

Since its launch contract with Arianespace using Russian Soyuz rockets fell apart due to Russia’s invasion of the Ukraine, OneWeb has been signing up a range of rocket companies, first SpaceX, then India, now Relativity. Apparently the satellite company realized it was a bad idea to depend on only one rocket, and is now lining up several to make sure its satellites can launch on schedule, no matter what.

For Relativity, this agreement solidifies its future, even before it has completed its first launch. It now has five customers for its Terran-R rocket, with contracts worth $1.2 billion. All it has to do now to become a major player in the global launch market is to get its rockets off the ground.

ISRO chief: India’s manned mission will be delayed

9:22 am

The new colonial movement: The head of India’s space agency ISRO revealed during a press conference following yesterday’s PSLV launch that he is delaying by one or two years Gaganyaan manned mission.

Indian Space Research Organisation (Isro) Chairman S Somanath on Thursday said the launch of the ambitious Gaganyaan mission, the country’s first manned space flight, cannot happen this year or next year as the agency is keen to ensure that all safety systems are in place.

Somanth’s comments confirm an earlier report. It appears he wants the agency to do at least two unmanned tests of the spacecraft’s crew abort system. He also want further tests of the GSLV rocket that will launch the manned capsule.

Somanth also indicated that India’s next attempt to land a rover on the Moon, Chandrayaan-3, might also be delayed from the presently scheduled August ’22 target launch as they review the lander’s systems.

FCC approves Starlink for moving vehicles; rejects DISH’s request to use Starlink wavelength

9:06 am

The FCC made two decisions yesterday that were both favorable to SpaceX’s Starlink satellite constellation.

First, it gave Starlink permission to provide service on moving vehicles such as cars, trucks, boats, and aircraft. Second, it rejected a DISH network request to use a wavelength in its ground-based system that is presently being used by both Starlink and OneWeb satellites.

This decision will continue the shift in communications from high-orbit/ground-based to low-orbit satellite constellations.

Glacial features in a Mars crater at 29 degrees south latitude?

3:56 pm

Glacial features in Mars crater
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on January 2, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). Simply labeled “slope features,” it was likely taken to monitor the gullies and streaks on the interior walls of this 4-mile-wide crater. Scientists have been using MRO to track the coming and going of frost on this crater’s interior walls since 2016.

Equally intriguing however are what appear to be squashed layers within the crater’s interior. These appear to be some form of glacial feature created by repeated climate cycles, similar to the glacial features routinely seen throughout the 30 to 60 degree mid-latitude strips north and south.

What makes the glacial features in this particular crater particularly intriguing is its location, as shown in the overview map below.

Today’s blacklisted American: Amazon employees demand company blackball everyone who disagrees with them

1:38 pm

The apparent goal of Amazon's woke employees
The apparent goal of Amazon’s woke employees

Persecution is now cool! Hundreds of Amazon employees have apparently signed a company-wide open letter demanding that the company immediately blacklist everyone who is anti-abortion while also blackballing every state that passes anti-abortion laws.

“As part of Amazon’s wide-reaching efforts toward a more inclusive and diverse workforce, we believe that Amazon cannot let this recent decision go unanswered,” the letter said. “We ask Amazon, the world’s best employer, to actively defend against this assault on our liberty.”

Among other actions, the authors are requesting that Amazon “allow employees of all genders the space and time to grieve, express their frustrations, and protest against this assault on our rights.” In addition, they want the company to “donate and match donations to bail funds” to help “women and pregnant people” seeking abortions in states with protections for pre-born babies.

It also demanded Amazon organize pro-abortion protests and donate money to the political organizations the letter signatories endorse.

Essentially, the letter calls for Amazon to focus its business entirely on leftwing political action rather than its central purpose of providing retail products to its customers. That such actions will cost the company money and possibly harm its profit line apparently does not matter to these employees.

The letter however went much farther. The cropped image from the letter below shows this:

The utter failure and total evil of government policies during the Wuhan panic

11:07 am

COVID mortality rates among children 10-14 in the UK
COVID mortality rates among children 10-14 in the United Kingdom,
comparing those who got the COVID shots versus those who did not

While stories about the ineffective and harmful consequences of the panic over the Wuhan flu continue to pour in on an almost daily basis, it is often better to step back and see these many stories in aggregate. By looking at the forest from a distance, a clearer picture frequently reveals itself that remains hidden if you only focus on studying the individual trees.

For example, the graph to the right, first published in January 2022, suggests strongly that giving young children the COVID shots only increased their mortality. This is just one story, however. Is it typical, or an outlier? You need to look at the larger picture to know.

Below I list and categorize the many science papers and news stories I have been collecting since my previous detailed two essays in May about the epidemic and its consequences (see: “The evidence keeps pouring in showing the utter failure of all COVID mandates” and “Are the COVID vaccines killing people over time? The data suggests yes.”). The totality of this data does appear shocking, especially because it makes evident the utter failure of almost every policy set by almost every government health official and elected politician since the Wuhan flu arrived in 2020.

First we must take another look at the new research about the mask mandates, policies that decades of research repeatedly showed would do nothing to protect anyone from COVID, and might even be unhealthy.

Mirror comparable to Hubble’s ready for JPL balloon astronomy mission

10:06 am

engineers attach panels to the mirror's support structure.
Engineers attach mirror panels to the mirror’s support structure.

An Italian optics company, Media Lario, has now completed construction of the primary mirror — at 2.5 meters width slightly larger than Hubble’s primary mirror — to be used on a JPL balloon astronomy mission dubbed ASTHROS, targeting a December 2023 launch.

The ASTHROS primary mirror features nine panels, which are significantly easier to fabricate than a one-piece mirror. The bulk of the mirror panels consist of lightweight aluminum, formed into a honeycomb structure that reduces its total mass. The panel surfaces are made of nickel and coated with gold, which improves the mirror’s reflectivity at far-infrared wavelengths.

Once launched, the balloon will circle the south pole for up to four weeks, taking data on the gas distribution in several galaxies.

While that data will be worthwhile, the mission’s real goal is to test these technologies for future space-based astronomy missions. If this mission works, it will reduce significantly the cost and time necessary to make big telescope mirrors, while enhancing the robotic capabilities of such telescopes.
