Real pushback: Thirteen university-run child mutilation clinics to shut down this year

1:45 pm

Owned for the purpose of mutilation and castration
Up to now, government-controlled apparently to allow their
mutilation and castration

Bring a gun to a knife fight: Because of pressure from state legislatures, up to thirteen university-run child mutilation clinics — falsely called “gender-affirming clinics” — are to shut down before the end of this year, with more shut downs likely next year as well.

Up to 13 pediatric gender clinics at university hospitals could close or scale back by the end of the year, as a result of Republican-led states restricting doctors from removing healthy organs or injecting hormones into minors who are confused about their gender.

In some cases, university youth gender clinics have already scaled back their operations as a result of state law. Litigation against the legislation could slow down or stop some clinics from closing. However, some are being closed while litigation proceeds.

The closures represent a quick change from just a year ago when The College Fix identified at least thirteen Republican-led states that funded pediatric gender clinics through universities, including Oklahoma, Florida and West Virginia.

Determining whether a Martian crater is impact or volcanic

Determining whether a Martian crater is impact or volcanic
Click for original image.

Overview map

Cool image time! The picture above, rotated, cropped, reduced, and sharpened to post here, was taken on March 22, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The camera team labeled this “Crater rim and ejecta,” which subtly reveals the picture’s scientific purpose.

The white dot on the overview map to the right indicates the location of this 15-mile-wide unnamed crater, about 150 miles northwest of where the rover Opportunity landed and traveled south to the rim of Endeavour Crater. It also shows in the inset that the crater appears to sit in the center of an upraised mound, suggesting it was formed not by impact but by volcanic processes.

This picture however says otherwise. The many small mounds and mesas to the south of the crater rim are not what one would expect on the apron of a volcano. Instead, they suggest this crater is an impact, with those mounds the eroded ejecta from that impact, now also partly buried by dust. This hypothesis is strengthened by the data from Opportunity, which found a great deal of impact ejecta during its travels, possibly from the very event that created this crater.

Will the wreck of the submersible Titan and the death of its five passengers impact space tourism?

10:57 am

OceanGate's Titan submersible
OceanGate’s Titan submersible

Three articles today all asked the same question as I pose above in the headline, noting the similarity in the business model of the deepsea tourism company OceanGate Expeditions and the burgeoning space tourism business, including both suborbital and orbital flights.

Without question there will be many more such articles in the coming days, as more information is gathered about what caused the failure of the Titan. As these three articles do, all will note the similarities and differences between deep sea tourism and space tourism.

First the differences. » Read more

Rocket Lab to attempt full recovery of first stage on next launch

9:46 am

In announcing the launch window, opening July 14th, for its next New Zealand launch, Rocket Lab also revealed that it will attempt the full recovery of the first stage after it splashes down softly in the ocean using parachutes.

Rocket Lab is also planning to conduct a marine recovery of Electron’s first stage as part of this mission. Rocket Lab’s recovery team will retrieve Electron using a customized vessel and transport the stage back to Rocket Lab’s production complex for analysis. Data from this recovered stage will inform Rocket Lab’s ongoing recovery and reuse program.

The company recently decided to forego any further attempts to snatch the first stage in the air before splashdown using a helicopter. Instead, it thinks it can recover the stage in good enough condition out of the water to use it or its engines again.

The launch itself will carry seven smallsats, four for NASA and three for two commercial companies.

House Democrats propose and Republicans approve Space Force increasing spaceport fees

9:37 am

We’re here to help you! The House Armed Services Committee, controlled by a majority of Republicans, has approved a defense funding bill that includes an amendment, proposed by a Democrat, that would allow the Space Force to charge much larger fees for the use of its spaceports.

Committee members signed off on the legislation June 22, which proposes $874 billion in defense spending. The full House is slated to vote on the bill in July. Included in the bill is an amendment offered by Rep. Salud Carbajal, D-Calif., that would allow the Space Force to collect fees from companies for the indirect costs of using the military’s launch ranges, like overhead infrastructure or other charges that a traditional port authority might impose on its users.

Today, per the Commercial Space Launch Act of 1984, the service is limited to collecting fees for direct costs like electricity at a launch pad. The law also restricts the Space Force from accepting in-kind contributions from commercial companies to upgrade its ranges.

The committee’s bill, if approved, would require commercial launch companies to “reimburse the Department of Defense for such indirect costs as the Secretary concerned considers to be appropriate.”

The bill also includes a Republican amendment that encourages the Space Force to charge other additional fees, or require private companies to do work the Space Force is presently handles.

Though the latter amendment might make sense, both amendments will likely achieve just one thing: making it much more expensive to launch from Cape Canaveral and Vandenberg. Whether those increased costs will be kept as low as possible is entirely unknown. We certainly should not trust officials in the federal government to do so.

Two ultraviolet images of Mars, taken six months apart

9:28 am

Mars in ultraviolet

The two images to the right, rearranged, cropped, and reduced to post here, were taken six months apart by the Mars orbiter MAVEN using its Imaging Ultraviolet Spectrograph (IUVS). From the press release:

The IUVS instrument measures wavelengths between 110 and 340 nanometers, outside the visible spectrum. To make these wavelengths visible to the human eye and easier to interpret, the images are rendered with the varying brightness levels of three ultraviolet wavelength ranges represented as red, green, and blue. In this color scheme, atmospheric ozone appears purple, while clouds and hazes appear white or blue. The surface can appear tan or green, depending on how the images have been optimized to increase contrast and show detail.

The first image [top] was taken in July 2022 during the southern hemisphere’s summer season, which occurs when Mars passes closet to the Sun. The summer season is caused by the tilt of the planet’s rotational axis, similar to seasons on Earth. Argyre Basin, one of Mars’ deepest craters, appears at bottom left filled with atmospheric haze (depicted here as pale pink). The deep canyons of Valles Marineris appear at top left filled with clouds (colored tan in this image). The southern polar ice cap is visible at bottom in white, shrinking from the relative warmth of summer. Southern summer warming and dust storms drive water vapor to very high altitudes, explaining MAVEN’s discovery of enhanced hydrogen loss from Mars at this time of year.

The second image [bottom] is of Mars’ northern hemisphere and was taken in January 2023 after Mars had passed the farthest point in its orbit from the Sun. The rapidly changing seasons in the north polar region cause an abundance of white clouds. The deep canyons of Valles Marineris can be seen in tan at lower left, along with many craters. Ozone, which appears magenta in this UV view, has built up during the northern winter’s chilly polar nights. It is then destroyed in northern spring by chemical reactions with water vapor, which is restricted to low altitudes of the atmosphere at this time of year.

Though of course not visible, the landing sites for Viking-1 (1976), Pathfinder (1997), and Franklin (2028) are captured in the bottom global image, as indicated by the white dots I have added. The two left dots are Viking-1 and Pathfinder respectively, located in the northern lowland plain dubbed Chryse Planitia. Franklin will land to the right, in the transition zone between those northern lowland plains and the southern cratered highlands.

Ariane-6 engineering test rocket at launchpad for engine tests

9:05 am

Ariane-6 test version at launchpad
Click for original image.

An engineering test version of ArianeGroup’s Ariane-6 rocket has arrived at the launchpad in French Guiana, where it will undergo a series of static fire engine and fueling tests.

As seen in this image [to the right] taken on 22 June 2023, the doors of this mobile gantry have been opened and the structure rolled back on rails. The operation, which takes about half an hour, was a trial run in preparation for a series test firings of the Vulcain 2.1 engine. These test firings will be conducted on the launch pad as part of ongoing preparations for the first-ever flight of Ariane 6. Removing the gantry for the first time – and then returning it – also helped validate the Ariane 6 ground infrastructure.

The Ariane 6 rocket visible here is not intended for flight. It is being used to check assembly procedures, electrical and fuel connections, telemetry, etc. Flight models, including the rocket that will make Ariane 6’s inaugural flight, are being built in Europe and integrated by prime contractor Ariane Group. After shipping to French Guiana, Ariane 6 core and upper stages are assembled horizontally, before being transferred to the launch pad and lifted upright inside the gantry, where the solid-fuel boosters and payload are attached. The horizontal assembly method cuts the time and cost of a launch campaign, and is a first for an Ariane rocket.

With only one Ariane-5 rocket launch left on its manifest, the European Space Agency desperately needs to get Ariane-6 off the ground and operational. It was originally supposed to make its first launch in 2020, thus overlapping the final launches of Ariane-5 by several years. At this moment it appears there will be a gap between when one rocket retires and the other begins flying.

SpaceX launches 56 more Starlink satellites

8:45 am

SpaceX this morning successfully launched another 56 Starlink satellites, with its Falcon 9 rocket lifting off from Cape Canaveral.

The first stage completed its eighth flight, landing on its drone ship in the Atlantic. The fairing halves completed their 7th and 10th flights, with the latter a new record.

The leaders in the 2023 launch race remain the same:

43 SpaceX
24 China
8 Russia
5 Rocket Lab

American private enterprise now leads China in successful launches 49 to 24 in the national rankings, and the entire world combined 49 to 40, with SpaceX by itself still leading the rest of the world, excluding other American companies, 43 to 40.

Why is this rare? School board members react in horror when hearing the porn they allow in schools

2:17 pm

Maybe no longer in Brainerd
Maybe the parents of Brainerd have finally decided their children
are theirs, not the government’s

In what seems to be the exception rather than the rule, when parents began reading the pornography that the Brainerd Public school district allowed in its school libraries, the school board members didn’t try to shut them up, but instead were horrified.

When Kevin Boyles, the board chair, attempted to move on from the public comment without addressing the concerns, [D.J.] Dondelinger told him to “hold on a second.” He told Boyles that he would like to make a motion to discuss the book at the next board meeting. “Something needs to be done,” Dondelinger said. “I’m shocked. We need to dig in and find out what the hell’s going on.”

He then proceeded to ask if “this stuff is accessible to fifth graders” and was told by the room of concerned citizens that yes, it was.

Boyles said that they would address the topic at the board’s retreat that took place on June 16, saying that he didn’t think a board meeting was the appropriate venue for a discussion about it initially. “I think it’s fair to say that several of us have questions,” he said.

Dondelinger pushed back, asking for a second to his motion to add the books to the agenda for the next school board meeting, to the applause of the audience.

I have embedded video of this board meeting, cued to when the parents begin reading. If you want to skip listening to badly written porn, Dondelinger’s demand for action begins at the 31 minute point of the video.

Biden administration announces India will sign Artemis Accords

1:08 pm

Modi meeting Biden upon arrival at White House June 21, 2023
Modi meeting Biden upon arrival at White House
on June 21, 2023

As part of the visit of Indian prime minister Narendra Modi to the U.S., the Biden administration today announced that India has agreed to sign Artemis Accords, becoming the 27th nation to join the American space alliance.

It appears India made this decision after the Biden administration agreed to foster a whole range of cooperative technology exchanges.

Cooperation in advanced computing, artificial intelligence, and quantum information science is also being fostered through the establishment of a joint Indo-US quantum coordination mechanism and the signing of an implementation arrangement on artificial intelligence, advanced wireless, and quantum technologies.

Both countries are working together on 5G and 6G technologies, including Open Radio Access Network (RAN) systems, with plans for field trials, rollouts, and scale deployments in both markets. “Here we’ll be announcing partnerships on open ran, field trials and rollouts, including scale deployments in both countries with operators and vendors of both markets. This will involve backing from the US International Development Finance, for cooperation and to promote the deployments in India,” the official said.

The US will support the removal of telecommunications equipment made by untrusted vendors through the US rip and replace program and welcomes Indian participation in this initiative.

The full list of signatories to the Artemis Accords is now as follows: Australia, Bahrain, Brazil, Canada, Columbia, Czech Republic, Ecuador, France, India, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Nigeria, Poland, Romania, Rwanda, Saudi Arabia, Singapore, South Korea, Spain, the United Kingdom, the United Arab Emirates, the Ukraine, and the United States.

One would hope that this decision would help separate India from China and Russia, but this is unclear.

There are other questions. » Read more
