The Cardigans – You’re The Storm

6:01 pm

An evening pause: Hat tip Dan Morris.

Readers: I am in need of evening pause suggestions! If you’ve seen something on the web that you think would fit, note this fact as a comment below. Do NOT post a link to your suggestion. I will email you and schedule it.

And if you’ve suggested previously, please feel free to email me some new stuff! The guidelines:

1. The subject line should say “evening pause.”
2. Don’t send more than three in any email. I prefer however if you send them one email at a time.
3. Variety! Don’t send me five from the same artist. I can only use one. Pick your favorite and send that.
4. Live performance preferred.
5. Quirky technology, humor, and short entertaining films also work.
6. Search BtB first to make sure your suggestion hasn’t already been posted.
7. I might not respond immediately, as I schedule these in a bunch.
8. Avoid the politics of the day. The pause is a break from such discussion.

Swirls and mesas in Valles Marineris

1:39 pm

Swirls and mesas in Valles Marineris
Click for full image. For the original of the inset go here.

Cool image time! The picture to the right, rotated and cropped to post here, was taken on June 13, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label as “fractures in West Candor Chasma,” one of the side canyons that form Mars’ gigantic Valles Marineris, the largest canyon system known in the solar system.

To my eye, I don’t see fractures as much as swirling and curving outcrop ridges, as if the twisted layering here is so steeply tilted so that it is almost vertical, with the more resistant edges sticking up out of the dust and dunes. The color corrected inset zooms in on some of these swirls, though this better view hardly clarifies things. Note how the upper curves seem to suddenly cut off, almost as if someone had sliced them with a knife. Don’t ask me to explain.

The overview map shows us where this spot is within Valles Marineris.

Today’s blacklisted American: Blacklisting is not enough, leftists now aim to get conservatives killed by police

11:48 am

The coming genocide
The left proves it really does want to round up its enemies and kill them

They’re coming for you next: Twice in the past two days Republican congresswoman Marjorie Taylor Greene (R-Georgia) has been swatted, with the police coming to her house armed and ready to fire because they had received a false report saying that a shooting had occurred there and that the situation was dangerous.

Two police officers rushed to Greene’s home in Rome, Ga., in response to a call they received at 2:53 a.m. The call, according to the Rome Police Department, was about “a male possibly shooting his family members and then himself.”

MSN reported that “the suspect, who called through an internet chat that appeared to be a suicide crisis line, falsely told police responders that a man ‘came out as trans-gender and claimed they shot the family’ at Greene’s address, the report said.” The caller gave his name as Wayne Greene and told police on the call: “If anyone tried to stop me from shooting myself, I will shoot them.” He also warned cops that “they would be waiting for us.”

At the house, there was, of course, no Wayne Greene. Rep. Marjorie Taylor Greene once again met the police officers at the front door, as she did in the early hours of Wednesday morning. They told her about the call and, according to the Rome Police Department, “confirmed this was a second false report.” The report added that the call can’t be traced, “due to the person(s) using a VPN.”

Called swatting, such false reports are expressly designed to harass the victim, and even get them killed should the police over-react and fire at the house out of fear of the non-existent gunman.

That this happened twice in two nights strongly suggests the caller truly wants this murder to happen. The caller even admitted to as much in a later recorded call to the police, in which the caller also admitted the motive was for political reasons. Greene’s political positions were unacceptable, and thus she must be removed:

FCC commissioner questions legality of FCC cancellation of SpaceX’s $900 million subsidy

9:15 am

On August 24th one of the four FCC commissioners, Brendan Carr, questioned the legality of FCC’s decision on August 10th to cancel the $900 million subsidy it had awarded SpaceX for providing internet capability to rural communities using Starlink.

The Federal Communications Commission denied Starlink nearly $900 million in rural broadband subsidies “without legal justification,” one of the regulator’s four commissioners said Aug. 24.

While the FCC was obligated to review subsidies provisionally awarded for SpaceX’s broadband service in December 2020, Commissioner Brendan Carr said the agency exceeded “the scope of that authority” when it rejected them nearly two years later.

…Carr said he was surprised to learn about the decision from a press release while he was on a work trip to Alaska, adding that it was made without a vote or authorization from the FCC’s Commissioners. [emphasis mine]

Carr also noted that the reasoning used by the FCC in its cancellation notice made no sense. For example, the FCC had referenced the cost SpaceX charges customers for buying the Starlink terminal, $599, in justifying the cancellation. Carr noted that “the FCC is not authorized to deny winning RDOF bids based on the price of equipment, ‘let alone based on an arbitrary one selectively applied to one winner.'”

When the cancellation was announced, I wrote that my first instinct was that it was solely political in nature, and that it stemmed from the growing animus in the federal bureaucracy and in the Biden administration to Elon Musk, combined with a lobbying effort by SpaceX’s competitors against Starlink. I think Carr’s statements this week confirm my instincts entirely. The cancellation was purely political.

Nonetheless, I think it a good thing the FCC cancelled this subsidy, which is really nothing more than welfare for big corporations. SpaceX doesn’t need it. The federal government doesn’t have the money. And the program itself is now clearly corrupt. The taxpayer would be better off if the entire subsidy program was shut down.

Cost overruns at Lockheed Martin threaten smallsat Lunar Trailblazer orbiter

8:56 am

NASA is now doing a review to decide if it will kill a smallsat lunar orbiter project, dubbed Lunar Trailblazer, due to cost overruns at Lockheed Martin.

Bethany Ehlmann, principal investigator for Lunar Trailblazer at Caltech, said in a presentation at LEAG Aug. 24 that Lockheed Martin, the spacecraft subcontractor, notified NASA of “recent and projected future overruns” on the project in June. Neither Ehlmann, NASA nor Lockheed Martin quantified those overruns.

“As we brought this mission from paper to life, the engineering and design efforts exceeded our original estimate,” Lockheed Martin said in a statement to SpaceNews Aug. 25. “Our Lockheed Martin team continues to implement cutting edge digital production tools and seek out operational efficiencies to minimize any extra cost incurred over Lunar Trailblazer’s development.”

The wording in this Lockheed Martin statement is meaningless blather, with no specific details. The bottom line however is this: Lunar Trailblazer was meant to demonstrate that it was possible to build a small low-cost science probe, in this case a lunar orbiter, and do it for no more than $55 million. Apparently, Lockheed Martin didn’t take that objective seriously. Instead, it thought it could do what it has done for decades — as have all the old big space contractors — pay no attention to cost, go overbudget, and then have NASA pick up the slack. It appears NASA might not do it this time.

Starliner manned launch delayed until 2023

8:42 am

NASA and Boeing yesterday announced that the first manned flight of a Starliner capsule has been delayed again, and will not occur before February 2023, at the earliest.

This delay is in order to fix the various thruster problems that occurred in the second unmanned demo flight in May 2021, dubbed OFT-2.

Nappi said some “debris-related conditions” likely caused those thrusters to shut down, but later noted that is their best estimate since the OMAC thrusters are in a service module that burns up on reentry and is not recovered. “We do not know where the debris may have come from,” he said. “The bottom line is that it looks to be the leading root cause, and we’ve eliminated that by looking at the CFT vehicle and making sure that there’s absolutely no debris in the system.”

Several reaction control thrusters also shut down during the mission, which Nappi said was likely due to low inlet pressures and can be addressed with a “tweak in timing and tolerances” in software. High pressures in a thermal control loop noticed in the mission were linked to filters that engineers determined are not needed and can be removed. A guidance system on the spacecraft called VESTA worked well but generated more data than the flight software could handle, requiring changes to the software. [emphasis mine]

The highlighted words indicate once again that there are quality control problems at Boeing. For any “debris” to get into the thrusters without notice means someone at some point wasn’t doing things right.

SpaceX and Boeing got contracts to fly humans on their commercial capsules at the same time, in 2014. SpaceX began those flights in 2020, about three years behind schedule, mostly due to NASA-imposed delays. Boeing has still not flown, with almost all its delays resulting from company failures, almost all of which were uncovered during the two unmanned demo flights in 2019 and 2022.

Hopefully, the company will finally get the last kinks from the system before next year’s flight. In the meantime its inability to get this job done on time has meant it has lost a lot of commercial business, all of which went to SpaceX.

T-Mobile and Starlink to team up

9:10 pm

SpaceX and T-Mobile today announced that sometime next year T-Mobile cell phones will use the Starlink satellite constellation to fill in any dead zones in its cell coverage.

T-Mobile says it’s getting rid of mobile dead zones thanks to a new partnership with SpaceX’s Starlink satellite internet, at an event hosted by T-Mobile CEO Mike Sievert and Elon Musk. With their “Coverage Above and Beyond” setup, mobile phones could connect to satellites and use a slice of a connection providing around 2 to 4 Megabits per second connection (total) across a given coverage area.

That connection should be enough to let you text, send MMS messages, and even use “select messaging apps” whenever you have a clear view of the sky, even if there’s no traditional service available. According to a press release from T-Mobile, the “satellite-to-cellular service” will be available “everywhere in the continental US, Hawaii, parts of Alaska, Puerto Rico and territorial waters.” The service is scheduled to launch in beta by the end of next year in “select areas,” and Sievert says he hopes it will someday include data.

The system will require Starlink’s second generation satellites, which right now also require SpaceX’s big Starship for launch. Once operational however it will work on the cell phones customers already own.

Chuck Yeager – Breaking the Sound Barrier

6:01 pm

An evening pause: From a 1950s Air Force documentary, describing Yeager’s flight on October 14, 1947. The 75th anniversary of this achievement is thus only two months away. From the YouTube webpage:

Two nights before the scheduled date for the flight, Yeager broke two ribs when he fell from a horse. He was worried that the injury would remove him from the mission and reported that he went to a civilian doctor in nearby Rosamond, who taped his ribs. Yeager told only his wife, as well as friend and fellow project pilot Jack Ridley, about the accident. On the day of the flight, Yeager was in such pain that he could not seal the X-1’s hatch by himself. Ridley rigged up a device, using the end of a broom handle as an extra lever, to allow Yeager to seal the hatch.

Hat tip Mike Nelson.

Eroding glacial ice on Mars, dipping in the wrong direction

1:00 pm

Dipping wrongway ice terraces
Click for full image.

Today’s cool image is a variation of a similar phenomenon shown in a cool image I posted in July, dipping terraced layers stepping downhill toward a cliff face, rather than away from the cliff as you would expect. That previous example was located in chaos region in the northern mid-latitudes that I dub glacier country.

This example is instead found a completely different region of Mars, halfway across the planet. The photo to the right, cropped, reduced, and annotated to post here, was taken on March 1, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The arrows indicate the downward trend of those dipping layers, toward the cliff face.

The overview map below provides the context.

Pushback? BLM murderer of retired black St. Louis police captain found guilty

12:09 pm

David Dorn: Some justice at last
David Dorn: Some justice at last

Two years after the BLM riots of 2020, the murderer of retired St. Louis police captain David Dorn has been found guilty.

A jury has convicted Stephan Cannon in the death of retired St. Louis police captain David Dorn in June 2020.

Cannon was found guilty Wednesday on charges of first-degree murder, first-degree robbery, first-degree burglary, and three counts of armed criminal action. He is scheduled to be sentenced in the case on the morning of September 13.

Dorn had been killed by Cannon because Dorn had responded to a burglary alarm during those BLM riots and was trying to prevent the looting of a friend’s pawn shop. He was the ultimate blacklisted American, murdered because he stood for law, justice, and civilized behavior.

Dorn’s widow, Ann Dorn, also a retired St. Louis police officer, made it very clear in an op-ed shortly thereafter who she really blames for her husband’s death.

How SLS reveals the difference between state-run propaganda and real journalism

10:10 am

The cost of SLS

On August 29, 2022, NASA will attempt the first launch of a government-built, government-owned, and government-designed rocket in more than a decade. The rocket’s development took more than eighteen years, moved in fits and starts due to political interference and mandates, cost more than $50 billion, and has been both behind schedule and overbudget almost from day one. Along the way NASA management screwed up the construction of one multi-million dollar test stand, built another it will never use, mismanaged that test program, dropped a rocket oxygen tank, and found structural cracks in an early Orion capsule.

This dubious achievement, even if the launch and month-plus-long mission of the Orion capsule to lunar orbit and back is a complete success, is hardly something to tout. NASA claims it and this rocket will make it possible for America to explore the solar system, but any honest appraisal of SLS’s cost and cumbersome design immediately reveals that claim to be absurd. SLS can launch at best once per year, and in truth will likely lift off at a much slower rate. It will also eat up resources in the American aerospace industry from technology better designed, more efficient, and more capable of doing the job.

Worse, the generally sloppy management of this program, with numerous major errors in design and construction, raises serious questions about the safety of any future manned flight.

And yet, as this launch day approaches, the American established press is going ga-ga over SLS. Below are just a small sampling:

Webb detects carbon dioxide in atmosphere of exoplanet

8:42 am

Scientists using the James Webb Space Telescope have detected carbon dioxide in the atmosphere of a hot gas giant exoplanet about 700 light years away.

WASP-39 b is a hot gas-giant with a mass roughly one-quarter that of Jupiter (about the same as Saturn) and a diameter 1.3 times greater than Jupiter. Its extreme puffiness is partly related to its high temperature (about 900° Celsius or 1170 Kelvin). Unlike the cooler, more compact gas giants in our solar system, WASP-39 b orbits very close to its star – only about one-eighth the distance between the Sun and Mercury – completing one circuit in just over four Earth-days. The planet’s discovery, reported in 2011, was made based on ground-based detections of the subtle, periodic dimming of light from its host star as the planet transits or passes in front of the star.

Previous observations from other telescopes, including the Hubble and Spitzer space telescopes, revealed the presence of water vapour, sodium, and potassium in the planet’s atmosphere. Webb’s unmatched infrared sensitivity has now confirmed the presence of carbon dioxide on this planet as well.

This is only the beginning. Astronomers have told me repeatedly that the most important area of research in astronomy in the next few decades will be the study of known exoplanets and their make-up. Webb is now a new tool in that effort. Combined with other telescopes looking at other wavelengths scientists will be able to identify a whole range of molecules in the atmospheres of these transiting exoplanets. We will begin to get our first glimpse into what other solar systems are like.
