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.
Russia and Venezuela sign space cooperation agreement
Even as the U.S. has gathered nineteen other countries — including most of the world’s space-faring nations — to sign the Artemis Accords protecting property rights in space, Russia yesterday announced that its government has approved its own space agreement with bankrupt and socialist Venezuela.
The agreement between the governments of the two countries was signed in Caracas on March 30, 2021. It is intended to create “organizational and legal foundations for mutually beneficial cooperation between the parties and relevant organizations of both states in the field of exploration and use of outer space for peaceful purposes.”
Russia also has an agreement with China, which like this Venezuela deal is somewhat vague. The countries have agreed to work together, but appear to have few plans for actual joint missions. What is clear is that both oppose the Artemis Accords.
Compared to the American alliance of nations, which includes Australia, Bahrain, Brazil, Canada, Columbia, France, Israel, Italy, Japan, Luxembourg, Mexico, New Zealand, Poland, Romania, Singapore, South Korea, the United Kingdom, the United Arab Emirates, and the Ukraine, the Russian alliance seems quite paltry, except for China.
Progress in completing the deployment of one of Lucy’s solar panels
Artist’s impression of solar panel
In the past month engineers for the Lucy asteroid mission have conducted a series of successful short tests to see if they can complete the unfolding of one of the probe’s two large solar panels.
On May 9, the team commanded the spacecraft to operate the array’s deployment motor using both the primary and back-up motor windings simultaneously to generate more torque, i.e. a harder pull. The motor operated as expected, further reeling in the lanyard that pulls the solar array open. After running the motor for a series of short intervals to avoid overheating, the team paused to analyze the results. Data from the spacecraft showed that the deployment was proceeding similarly to engineering ground tests, allowing the team to move forward with the second stage of the attempt. Analysis of the data also suggested that there was still additional lanyard to be retracted. The team sent the same commands again on May 12. Although this series of commands did not latch the solar array fully open, it did advance the deployment enough to increase the tension that stabilizes the arrays as was hoped.
On May 26, the spacecraft was again commanded to deploy the solar array. As in the first two attempts, both motor windings were operated simultaneously for short periods of time to avoid overheating. Afterwards the team again analyzed the data from the event, which again showed that the array was continuing to open. The team repeated the deployment command sequence a fourth time on June 2. While the array still did not latch, the data indicates that it continued to further deploy and stiffen throughout the attempt.
The graphic above illustrates the problem. The engineers will attempt further windings, and still hope the panel will open entirely and latch. If not, the stiffening suggests the panel will still stabilize in this open position, which up to now has been sufficient to produce about 90% of the power predicted and enough to complete the mission.
Vulcan likely delayed until ’23
According to Eric Berger at Ars Technica, continuing delays with both the rocket’s payload and main engines, ULA’s Vulcan rocket will almost certainly not launch before the end of this year, as hoped by the company.
The rocket’s first stage BE-4 engines are being built by Blue Origin, and are already four years behind schedule. According to Berger’s sources, they will not be delivered to ULA until mid-August, which makes a launch in ’22 very unlikely, especially because both the engines and rocket are new, and will need time for fitting and further testing as a unit.
As for the payload, Berger’s assessment is not based on any new information. The payload, Astrobotic’s first lunar lander dubbed Peregrine, has also been experiencing delays, but the article provides no further information on whether it will miss its targets to be ready in ’22.
Regardless, it appears that Blue Origin is still dragging in its effort to build the BE-4 engine. If Vulcan cannot launch this year, it will threaten ULA’s long term future, since the company is depending on it to replace its Atlas-5 and Delta rockets. The delays now are allowing others to catch up and grab business that ULA might have garnered had Vulcan been operational as planned.
Webb gets its first large micrometeoroid impact
In a carefully worded press release this week, NASA revealed that one segment of the primary mirror of the James Webb Space Telescope had been hit by a micrometeoroid.
Between May 23 and 25, NASA’s James Webb Space Telescope sustained an impact to one of its primary mirror segments. After initial assessments, the team found the telescope is still performing at a level that exceeds all mission requirements despite a marginally detectable effect in the data. Thorough analysis and measurements are ongoing. Impacts will continue to occur throughout the entirety of Webb’s lifetime in space; such events were anticipated when building and testing the mirror on the ground.
The reason such events were expected is because — unlike most telescopes (including Hubble) — Webb’s mirrors are not enclosed in a tube for protection. To do so would have made the telescope far too expensive to build or launch.
After describing in great detail all the work done prior to launch to anticipate such hits and deal with them, the press release then mentioned this fact almost as an aside:
This most recent impact was larger than was modeled, and beyond what the team could have tested on the ground.
Localized damage to the primary mirror of any telescope is not unusual. With ground-based telescopes such issues are not infrequent and easily worked around. The same applies to Webb. The engineers will calculate how to calibrate this particular segment to minimize distortion from the impact.
However, that the telescope experienced a hit larger than ever modeled, so soon after launch, suggests that those models were wrong, and that larger and more frequent hits can be expected. If so, this could be very worrisome, as over the long run it could shorten the telescope’s life in space significantly.

Close-up on another flaky Martian rock
Click for full image.
Click for interactive map.
Cool image time! The picture above, reduced to post here, was taken by Curiosity’s high resolution camera on June 5, 2022 (sol 3494). It shows a close up of another flaky rock near where the rover is presently sitting (the blue dot on the map to the right), similar to the one that I highlighted on May 28, 2022 but zoomed in closer.
Not only can you seen the layered flakes extending out from the rock’s main body, you can see what appear to be small deposits of material between the flakes, as if at one point the material was being placed here by condensation, either from the atmosphere or liquid.
The curvy rounded edges of the rock’s larger flakes could have been caused by the same process, or by long slow wind erosion over the eons since the flakes were formed.
The photo appears to be part of a larger mosaic that the rover’s science team is having the camera take of the strange geology that now surrounds Curiosity. The science team also appears to be continuing its beeline south towards the rover’s original planned route, indicated by the red dotted line on the map. The green dot marks the approximate location of a seasonal recurring dark streak on the cliffside, suggesting some form of seepage, while the white arrows mark a distinct layer that scientists have identified in many places on the flanks of Mount Sharp.
