Today’s blacklisted American: School officials attempt to censor and shut down conservative club at Utah high school
Copper Hills HS: No free speech allowed for conservatives!
Persecution is now cool! School officials at Copper Hills High School in West Jordan, Utah, have repeatedly attempted to censor and block the conservative Turning Point USA chapter there, first by making it difficult for the students to form the club, then by telling them they had to remove some signs as well as always include opposing points of view in their displays. When the students objected these school officials then shut down their gathering entirely.
The specific oppressive actions of the school’s principal, Bryan Veazie, and his assistant principal, Rufine Einzinger (both reachable here), are well described in the letter [pdf] sent to Tracy J. Miller, the President of the Board of Education for the Jordan School District, by the Alliance Defending Freedom (ADF), which is representing the students:

Dusty Gale Crater in the winter
Click on image for full resolution panorama. For original photos, go here, here, here, here, and here.
Click for interactive map.
Cool image time! The panorama above, created from five images taken by Curiosity’s left navigation camera on May 25, 2022, looks north across the floor of Gale Crater at its rim about 25 miles away.
The butte on the left I think (though I am not certain) is the backside of the same butte seen from the front in December 2021. Then, Curiosity was below it looking up. Now, Curiosity is above it looking down.
For scale, that butte is about ten feet high. Navarro Mountain on the right is about 450 feet high, but looks less impressive because it is farther away.
It is now winter in Gale Crater, a time period when there is more dust in the atmosphere. This fact becomes very evident if you compare this panorama with a similar one taken in December 2021 in the Martian fall. Then, the air is crystal clear, and the rim can be seen in great detail. Now, though visible (barely) on the left, the haze makes the more distant peaks on the right almost invisible.
Curiosity has climbed about 1,750 feet since it landed in 2012. It is still about 12,600 feet below the peak of Mount Sharp. The blue dot and yellow lines in the overview map to the right indicates Curiosity’s location when the panorama was taken, and the approximate area covered by it.
Be sure and look at the full resolution panorama, especially the section near the middle, where the dramatic nature of this terrain is most evident.
Stratolaunch test flight of Roc ends prematurely
Capitalism in space: A recent Stratolaunch test flight of its giant carrier airplane Roc was ended prematurely because engineers had detected an unexpected “test result”.
“While completing Roc testing operations, we encountered a test result that made it clear we would not achieve all objectives for this flight,” the California-based company, which was created by Microsoft co-founder Paul Allen more than a decade ago, said in Twitter update. “We made the decision to land, review the data, and prepare for our next flight.”
The company has provided little additional information. The flight itself was planned to last as much as 3.5 hours, but only lasted about an hour and a half.
Stratolaunch’s present plan is to offer Roc and its Talon-A payload as a testbed for testing hypersonic flight.
Delay in Psyche launch wrecks smallsat asteroid mission
The two month delay in the launch of NASA’s Psyche asteroid mission because of software issues has apparently wrecked a smallsat asteroid mission that was to launch as a secondary payload on the Falcon Heavy rocket.
Janus, a NASA smallsat mission selected in 2019, will launch two identical spacecraft as secondary payloads on the Falcon Heavy rocket whose primary payload is Psyche. After a series of Earth flybys, each Janus spacecraft was to fly by different binary asteroids, designated 1996 FG3 and 1991 VH.
However, the mission’s principal investigator said June 8 that mission plan is no longer possible. Speaking at a meeting of NASA’s Small Bodies Assessment Group (SBAG), Dan Scheeres of the University of Colorado noted that mission plan assumed Psyche launched in August of this year as previously planned. NASA announced May 23 that the mission’s launch had been delayed to no earlier than Sept. 20 to provide more time for testing the spacecraft’s software.
With the revised launch date, he said it’s no longer possible for the spacecraft to perform those Earth flybys with the existing spacecraft design. “Those flybys were essential for setting up our flybys of our target binaries, 1991 VH and 1996 FG3,” he said.
The Janus team are right now scrambling to see if they can find other asteroids the spacecraft can reach, based on the new launch date. Their work however is badly hampered by the uncertainty of that date, which could still change for many reasons.
The heart of the problem, as Scheeres notes, is its status as a secondary payload.
“We have no ability to influence the launch dates or the targeting of the launch vehicle, and that arises from our status as a rideshare,” he said.
The article also describes two other NASA interplanetary smallsat missions that have been badly hindered because of their status as secondary payloads. All three stories strongly suggest that in the future it will make much more sense to put such missions on its own rocket, as the primary payload. This is what NASA did with its CAPSTONE smallsat mission to the Moon, which will launch on a Rocket Lab Electron rocket sometime before the end of the month.
Update on Starship in Texas and Florida
Link here. The article goes into great detail describing the status of the Superheavy booster prototype and the Starship prototype now planned for that first orbital launch, with this comment:
While some claim FAA is the hold up for Starship plans [I wonder who], even if the FAA had approved a launch in December of last year, SpaceX likely still would not have been ready for an orbital launch.
Maybe so, but why do journalists today have to bend over backwards making believe the federal government is not a problem, or is not interfering with this private company’s operations? It clearly is a problem, and is interfering with private companies, and it is doing so more and more for political reasons. Good reporting must note this.
The report also provides details on the status of SpaceX’s Florida Starship orbital launchpad. The company only began serious construction in Florida in April, yet large sections of the launch tower as well as its foundation have already been built. The pace of construction — as well as SpaceX’s past history building the Boca Chica launchpad — suggests this launchpad could be ready before the end of the year.
Compare that with NASA’s incompetent effort to build its SLS mobile launchers. The contrast is striking.

Today’s blacklisted American: Republican candidate for Michigan governor arrested by FBI
Ryan Kelley: a target for arrest for being a Republican
Blacklists are back and the Democrats have got ’em: One day after President Joe Biden joked on television with Jimmy Kimmel about “sending [Republicans] to jail,” the FBI arrested Ryan Kelley, one of the Republicans running for Michigan governor, on misdemeanor charges for daring to stand on the steps of the Capitol building on January 6, 2021, but never entering it.
Kelley is charged 17 months after the Jan. 6 riot and on the same day the House committee investigating the Jan. 6 attack on the U.S. Capitol is to hold a primetime hearing Thursday to present never-seen video, new audio and a mass of evidence following a year-long investigation by the select panel.
The criminal complaint obtained by Fox News Digital charged Kelley with: knowingly entering or remaining in any restricted building or grounds without lawful authority; disorderly and disruptive conduct in a restricted building or grounds; knowingly engaging in any act of physical violence against person or property in any restricted building or grounds; willfully injure or commit any depredation against any property of the United States. All are misdemeanor offenses. [emphasis mine]
SLS’s 2nd mobile launcher to cost more than $1.5 billion, 3x what was initially budgeted
NASA’s bloated SLS mobile launchers
According to an inspector general report [pdf] released today, the second mobile launcher being built by the company Bechtel to transport its SLS rocket from the assembly building to the launch site is likely going to cost more than $1.5 billion, three times what was initially budgeted, and will not be completed any earlier than the end of 2027, four years behind schedule.
Compounding Bechtel’s projected cost increases and schedule delays, an ML-2 [mobile launcher-2] project analysis provided only a 3.9 percent confidence level that the nearly $1 billion cost [twice the original budget] and October 2025 [2.5 years late] delivery estimates were accurate. NASA requires projects to develop budgets and schedules consistent with a 70 percent joint cost and schedule confidence level (JCL), meaning a 70 percent likelihood the project will finish equal to or less than the planned costs and schedule. In fact, an Independent Review Team analysis determined the project would require an additional $447 million and 27 months, for a total contract value of $1.5 billion and a launcher delivery date of December 2027—a schedule that would enable an Artemis IV launch no earlier than the end of 2028.
The first mobile launcher, shown on the left in the graphic, cost more than $1 billion and will used only three times, at most. The second, on the right, is required for all of the assigned interplanetary tasks being given to the full size version of SLS beyond those first three test flights. Without it that version of SLS cannot launch. And even if the launcher is ready by 2028, as the IG report suggests, that will be more than a decade behind schedule, and six years from now.

Chinese scientists detect a fast radio burst that defies the theories
The uncertainty of science: Using their large FAST radio telescope, Chinese scientists revealed this week that they have detected a new fast radio burst (FRB) whose behavior and location does not fit the present tentative theories for explaining these mysterious deep space objects.
The FRB was an exception from the beginning as it flared again and again in observations recorded by the Five-hundred-meter Aperture Spherical radio Telescope (FAST), which nestles among the hills of China’s Guizhou province. The multiple flares put the source among the few percent of FRBs that repeat. But unlike most repeaters, this one doesn’t have any apparent cycle of bursting and quiescence.
“FRB 20190520B is the only persistently repeating fast radio burst known so far, meaning that it has not been seen to turn off,” Li says.
In addition, whatever made the FRB is also emitting a constant buzz of radio waves. Astronomers have found an association with a persistent radio source in only two other FRBs, and for one of these the low-level radio waves seem to come from ongoing star formation in the host galaxy. For FRB 20190520B, though, the radio source is far more compact, and Li’s team thinks the radio waves probably come from the FRB source itself.
The data also suggests the location does not fit the theories, and even suggests that FRBs might not all come from magnetars, as presently proposed.
Amino acids found in asteroid samples brought back from Ryugu
Japanese scientists revealed this week that they have detected more than 20 types of amino acids in the asteroid samples brought back from Ryugu by the probe Hayabusa-2.
Kensei Kobayashi, professor emeritus of astrobiology at Yokohama National University, said the unprecedented discovery of multiple types of amino acids on an extraterrestrial body could even hint at the existence of life outside of Earth. “Proving amino acids exist in the subsurface of asteroids increases the likelihood that the compounds arrived on Earth from space,” he said.
It also means amino acids can likely be found on other planets and natural satellites, hinting that “life could have been born in more places in the universe than previously thought,” Kobayashi added.
Let me emphasize that this is not a discovery of life on Ryugu, only chemistry that is found in life on Earth. Such chemistry however can be found outside of life as well. What this detection suggests however that it is relatively common to produce such complex chemistry in hostile space environments, which increases greatly the possibility of life everywhere in the universe.
