Dormant volcanic vent on Mars

12:36 pm

Dormant volcanic vent on Mars
Click for original image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on November 19, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the science team labels “Intersecting Fissures.”

These fissures stand out distinctly on this terrain. If you look at an MRO context camera image, showing a wider view, you can see that the surrounding plain is relatively featureless, with few craters. Except for some strange and inexplicable dark streaks close by to the east, some mottled but flat terrain to the north, and a long but very faint similar east-west fissure to the south, this runelike fissure is the only major topological feature for miles around.

That context camera image also shows that this fissure sits on top of a very faint bulge, with hints that material had flowed downhill from the fissure’s western and southern outlets. Located very close to the equator, it is unlikely that any of those flow features are glacial, and in fact they do not have that appearance in the context camera picture. Instead, they have the look of Martian lava, fast-moving and far less viscous than Earth-lava, and thus able to cover large areas much more quickly.

Thus, all the evidence says that this feature is a dormant volcanic vent, sitting on a flood lava plain. And the overview map below cements this conclusion.

Today’s blacklisted American: Previously blacklisted Oregon professor sues university for being further blacklisted because he tweeted “all men are created equal.”

They’re coming for you next: Professor Bruce Gilley of Portland State University in Oregon, who previously had a peer-reviewed paper on colonialism withdrawn from publication because of death threats, has now sued the university because the former communication manager for its Division of Equity and Inclusion blocked him from an internal college Twitter discussion group because he had the nerve to tweet “all men are created equal.”

You can read his lawsuit complaint here [pdf]. Gilley not only sued the university’s Division of Equity and Inclusion, he also sued directly Tova Stabin, the communications manager who blocked him.

What makes the case interesting is that the day after he filed his lawsuit, the university unblocked him and its lawyer sent him an apologetic letter. Here is part of that letter, as quoted in the lawsuit complaint:

The landing sites for two upcoming lunar landers

9:51 am

Map of Moon's south pole
Click for interactive map.

The approximate landing sites for two different lunar landers have now been revealed.

The map to the right, with the south pole indicated by the white cross, shows both, plus the planned landing site for Russia’s Luna-25 lander, presently targeting a summer ’23 launch. The green dot marks Luna-25’s landing site, inside Boguslawsky Crater.

The red dot marks the landing site in for India’s Chandrayaan-3 lunar lander/rover, now tentatively scheduled for launch by the end of ’23. This mission will put a small rover on the surface, and is essentially a redo of the failed Chandrayaan-2 mission from 2019.

The yellow dot in Malapert-A crater is now the likely landing site for Intuitive Machines Nova-C lander. This site is a change from the spacecraft’s original landing site in Oceanus Procellarum (where Astrobotic’s Peregrine lander is now going). In making this change, the launch of Nova-C also slipped to late June 2023, from the previously announced launch date of early 2023.

ULA stacks Vulcan-Centaur rocket for ground tests prior to first launch

9:14 am

ULA’s new Vulcan-Centaur rocket has finally been stacked in the company’s assembly facility at Cape Canaveral, ready to be rolled out for its first launchpad fueling tests prior to its first launch, tentatively scheduled for the end of March.

The odds of that launch date being met is quite uncertain. Right now neither the rocket’s payloads nor its solid rocket strap-on boosters have been added, and before that will happen the company plans to first roll the rocket out to the launchpad, do fueling and countdown tests. It will then roll it back to the assembly building to stack those components, and then roll it back to the launchpad for launch.

To meet that launch target everything must go perfectly during these preliminary operations, something that is generally unexpected for a rocket’s first launch. ULA however has an advantage, in that it has already done much of this testing using a dummy Vulcan, and it also has decades of experience launching rockets.

Much rides on this first launch. The payloads include Astrobotic’s first lunar lander, Peregrine, as well as Amazon’s first two test satellites for its Kuiper internet constellation. Also, ULA needs to complete two successful launches in order to get certified to begin its commercial launches for the military.

Virgin Orbit narrows cause of launch failure to $100 component

9:04 am

Though its investigation is not completed, Virgin Orbit has narrowed the cause of its January 9th launch failure from Cornwall to a $100 component in the second stage engine of its LaunchOne rocket.

Speaking on a panel at the SmallSat Symposium in Mountain View, California, Dan Hart said it was still premature to formally declare the root cause of the failed Jan. 9 flight of the company’s LauncherOne rocket on the “Start Me Up” mission from Spaceport Cornwall in England. However, he said while that investigation continues, evidence was pointing to a component in the rocket’s second stage engine.

“Everything points to, right now, a filter that was clearly there when we assembled the rocket but was not there as the second stage engine started, meaning it was dislodged and caused mischief downstream,” he said. He didn’t go into details about that component, other than to say that it was not an expensive item. “This is like a $100 part that took us out.”

Hart said the company would no longer use that filter and was “looking broadly” at other potential fixes.

No timeline as to when the company will complete the investigation or resume launches has been released. Since both the FAA and the UK’s Air Accidents Investigation Branch are involved, we should expect it to take longer than necessary.

Relativity’s Terran-1 rocket on launchpad for final tests prior to first launch

8:59 am

Relativity has once again stacked its Terran-1 rocket on its launchpad at Cape Canaveral for its final ground tests prior to first launch, hopefully later this month.

The launch date has not been announced, nor has a specific schedule for those tests, which will likely include several dress rehearsal countdowns where the rocket will be fueled as if for launch.

Terran-1 is a smallsat rocket, most of which has been 3D printed. If successful, Relativity plans to follow it in 2024 with the 3D printed Terran-R, which would be comparable in size and power to SpaceX’s Falcon 9. The company also claims that rocket will be entirely reusable.

Today’s blacklisted American: Leftist professor fired by university for questioning its racist agenda

12:20 pm

They’re coming for you next: English instructor Ryan Hall, a self-described leftist “who has never voted for a conservative in my life,” was fired by Western Kentucky University when he questioned its leftist and racist Diversity, Equity, and Inclusion (DEI) agenda that was also leaving students fearful to speak their minds out of fear of being punished.

From the second link:

“While I may not categorize myself as a conservative, the assaults on free speech, self-reliance, meritocracy, the family, science, and truth should alarm everyone,” Hall said in an email interview this month with The College Fix. “Many have pointed out that our institutions of higher education increasingly look like the temples for a state religion attempting to create hierarchies based on byzantine and bogus ideas; such systems have never worked out well historically, no matter how many newly minted sinecures suggest otherwise,” he said.

Hall told The Fix he had canceled all of his classes, five of them, for a week while he confronted his university about its bias in February 2022. “They fired me that same month after a few days of discussion. … They fired me because I would not return until we reached an agreeable solution, not because of the classes I had canceled, according to the email I received,” Hall said.

The first link above goes to an op-ed Hall wrote for an organization called the Foundation Against Intolerance & Racism, which appears to be a loose coalition of Substack writers opposed to the bigoted policies of most universities. In that op-ed Hall added these facts as to why he challenged his superiors at Western Kentucky:

Perseverance and Ingenuity begin the journey up onto Jezero Crater’s delta

11:17 am

Perseverance's view ahead, February 7, 2023
To see the original images, go here and here.

Overview map
Click for interactive map.

After two years of detailed exploration on the floor of Jezero crater, the rover Perseverance and its Mars helicopter scout Ingenuity have finally begun the climb up onto the delta that in eons past flowed into Jezero Crater.

The panorama above was created from two Perseverance images taken by its right navigation camera on February 7, 2023 (Sol 699) (here and here), looking forward and uphill. On the overview map to the right the blue dot marks Perseverance’s location, with the yellow lines indicating the approximate area covered by this mosaic. The red dotted line in both images indicate approximately the rover’s eventually path.

Ingenuity’s present position is marked by the green dot. This is where the helicopter landed after completing its 42nd flight on February 4, 2023. Planned to fly 823 feet for 137 seconds, Ingenuity actually flew a slightly shorter distance, 814 feet, in that length of time. The difference is probably the result of Ingenuity’s need to find a good landing spot, and the one it found was slightly closer to its take-off point.

The flight however took the helicopter uphill, scouting the terrain that Perseverance plans to drive. While there is no terrain here that is much of a challenge for the rover, having the helicopter’s ground images in advance allows its operators to plan longer drives, as those images will help tell them what obstacles to avoid and route to choose.

The green oval indicates the area that Perseverance has left its first ten core samples for later pickup and return to Earth.

Space Force to do major cleanup of diesel fuel spill on Hawaiian mountaintop

9:36 am

Space Force officials yesterday announced that it will to do major cleanup of the diesel fuel spill that occurred on the top of the mountain Haleakala on the Hawaiian island of Maui last week.

The plan is to remove about 200 cubic yards of fuel-tainted soil, test the base of the dig, and then determine if more soil has to be removed.

The official making this announcement apologized repeatedly for the spill, so much so it was almost as if he was on his face on the ground, kow-towing. It of course made no difference. The leftist race-baiters in Hawaii made it clear where they stood on the matter.

On Friday, the Hawaiian rights group Kākoʻo Haleakalā called for the removal of all telescopes from the peak of Haleakala. The military “showcased their incompetence and lack of human decency when they allowed more than 700 gallons of diesel fuel to be spilled atop Haleakalā,” the group said in a statement.

“This is just the most recent example of how U.S. imperialism and military hegemony is protected in the Pacific while Hawaiians are ignored and our ʻāina is violated,” the statement said, using the Hawaiian term for land.

Let me translate: “We hate whites and America, and we want you out of Hawaii, now. And if you don’t go, we want you to cede all control to us, so that we treat you as the inferior beings we consider you to be.”

Note too that this group’s agenda is identical to the agenda of the race-baiters on the Big Island who are blocking construction of the Thirty Meter Telescope and are forcing the removal of telescopes there.
