Dry ice and carbon monoxide detected on asteroids beyond Neptune

9:31 am

Based on new infrared observations by the Webb Space Telescope, scientists have detected for the first time carbon dioxide and carbon monoxide on asteroids beyond Neptune. From the abstract of their paper:

Out of 59 [trans-Neptunian objects] and centaur [asteriods] observed by the James Webb Space Telescope and the NIRSpec Integral Field Unit as part of the DiSCo-TNOs project, we report the widespread detection of CO2 ice in 95% of the sample and CO ice in 47% of the sample.

It appears dry ice is ubiquitous in the outer solar system. Since it is believed these asteroids are very primitive, this data suggests there was a lot of it in the early solar system when the planets were forming.

The discovery of so much carbon monoxide is however more puzzling, as it is expected to sublimate away even in the very cold environment so far from the Sun and is therefore likely not from the early solar system. The scientists posit that it might have been produced when radiation transformed the other carbon-bearing ices.

Scientists confirm 2023 data that suggested active volcanism on Venus

9:20 am

Active lava flows on Venus
Click for original video

Scientists have now confirmed a 2023 paper that had found evidence in archival data from the Magellan orbiter that there was active volcanism on Venus. From the abstract of the new paper:

To investigate more widespread alterations that have occurred over time in the planet’s surface morphology, we compared radar images of the same regions observed from 1990 to 1992 with the Magellan spacecraft. We found variations in the radar backscatter from different volcanic-related flow features on the western flank of Sif Mons and in western Niobe Planitia. We suggest that these changes are most reasonably explained as evidence of new lava flows related to volcanic activities that took place during the Magellan spacecraft’s mapping mission with its synthetic-aperture radar.

The image to the right is a screen capture, annotated to post here, from a video computer animation created by the science team based on that Magellan data. The red areas are where the scientists detected lava flow changes on the flanks of the volcano Sif Mons. From the press release:

Using flows on Earth as a comparison, the researchers estimate new rock that was emplaced in both locations to be between 10 and 66 feet (3 and 20 meters) deep, on average. They also estimate that the Sif Mons eruption produced about 12 square miles (30 square kilometers) of rock — enough to fill at least 36,000 Olympic-size swimming pools. The Niobe Planitia eruption produced about 17 square miles (45 square kilometers) of rock, which would fill 54,000 Olympic swimming pools. As a comparison, the 2022 eruption of Mauna Loa in Hawaii, Earth’s largest active volcano, produced a lava flow with enough material to fill 100,000 Olympic pools.

There is uncertainty of course with this result, due to the difficulty of analyzing radar data properly. Nonetheless, this result reinforces last year’s results, which saw evidence of changes between the two Magellan data sets in a different region near the volcanoes Ozza Mons and Maat Mons. It also reinforces previous work going back decades that has repeatedly suggested Venus was volcanically active.

Dwayne O’Brien – We Remember

6:01 pm

An evening pause: To the men who flew the planes.

And all who’ve coursed through hostile skies,
Know that freedom requires a sacrifice,
To those who paid the highest price,
We remember.

With a place of honor so deserved,
For what flesh and blood and steel have earned,
That may the glory be reserved,
For the colors they so bravely served.

Keep them flying, keep them flying,
So that all who see them will know,
That our freedom was won by the blood that flowed,
And we remember.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. All editions can also be purchased direct from the ebook publisher, ebookit, in which case you don't support the big tech companies and the author gets a bigger cut much sooner.

North Korea’s orbital Chollima-1 rocket explodes shortly after launch

2:48 pm

North Korea’s third launch of its orbital Chollima-1 rocket, supposedly carrying a spy satellite, failed today when the first stage exploded shortly after launch.

North Korea’s official state news agency said it launched a spy satellite aboard a new rocket from its main space centre tonight. But it added that the rocket blew up during a first-stage flight soon after liftoff due to a suspected engine problem.

Video of the explosion showed up on social media almost immediately. I have embedded that video below.

Based on when the explosion occurred — early in the flight — and the planned flight path east from North Korea’s west coast Sohai spaceport, the rocket debris very likely crashed inside North Korea, its toxic hypergolic fuels pouring down possibly in habitable areas.

Pressure from free-speech law firm forces Chase to eliminate language that allowed it debank conservatives

11:57 am

JP Morgan Chase: eager to blacklist you for your opinions
Maybe slightly less eager, but only slightly less

Bring a gun to a knife fight: For reasons that appear related to pressure from the conservative free-speech law firm the Alliance Defending Freedom (ADF), JPMorgan Chase has eliminated language in its payment services policy statement that allowed it to cancel conservative clients merely because it disliked those clients’ politics.

JPMorgan Chase, the largest bank in the U.S., rolled back its WePay service that required merchants to refrain from accepting payments or using the service for activities related to “social risk issues,” which the bank defined as anything “subject to allegation and impacts related to hate groups, systemic racism, sexual harassment and corporate culture.”

The language was removed from the company’s WePay terms of service, the Alliance for Defending Freedom (ADF) discovered this month.

For the past three years ADF has issued what it calls its Viewpoint Diversity Score Business Index, designed to “measure corporate respect for free speech and religious freedom across 43 performance indicators.” Each year it consults with the 85 corporations on its list in an attempt to get them to eliminate policies that encourage the debanking of conservative individuals or organizations. In the case of Chase, a sustained effort over two years eventually caused the company to remove that language.

Today’s Blacklisted American: To celebrate Memorial Day, a federal official bans the American flag

11:09 am

Brooke Merrell:
Brooke Merrell: Proud to ban the American flag

In another example of the fundamental hostility that federal officials feel for their country, officials at Alaska’s Denali National Park recently told contractors working in the park they were forbidden from flying Old Glory on their trucks and equipment, as construction workers have done for more than a century.

According to the contractor, Denali National Park Superintendent Brooke Merrell contacted the man overseeing the federal highways project, claiming there had been complaints about the U.S. flags, and notifying him that bridge workers must stop flying the stars and stripes from their vehicles because it detracts from the “park experience.”
Denali National Park Superintendent Brooke Merrell

“The trucks are flying these American flags, about a foot atop the trucks, about three-foot by four-foot flags, and they said they don’t want this,” the contractor explained. “They’re saying it isn’t conducive and it doesn’t fit the park experience.”

Up until this week, however, the flags were displayed without incident. It was only when the park began running tour buses that the order was given to take down the flags, he added.

Visiting a galactic bar

9:27 am

Visiting a galactic bar
Click for original image.

Cool image time! The picture to the right, reduced and sharpened to post here, was taken by the Hubble Space Telescope as part of a research project studying the flow of gases inside barred galaxies. It shows a spiral galaxy, NGC 4731, edge on, located about 43 million light years away. From the caption:

Barred spiral galaxies outnumber both regular spirals and elliptical galaxies put together, numbering around 60% of all galaxies. The visible bar structure is a result of orbits of stars and gas in the galaxy lining up, forming a dense region that individual stars move in and out of over time. This is the same process that maintains a galaxy’s spiral arms, but it is somewhat more mysterious for bars: spiral galaxies seem to form bars in their centres as they mature, accounting for the large number of bars we see today, but can also lose them later on as the accumulated mass along the bar grows unstable. The orbital patterns and the gravitational interactions within a galaxy that sustain the bar also transport matter and energy into it, fuelling star formation.

Astronomers don’t really understand why these barred structures develop, since you would expect the overall gravity of the galaxy would promote a spiral or spherical shape. There must are factors not yet understood or completely identified (such as the magnetic fields of such galaxies).

South Korea establishes its own version of NASA

9:08 am

The South Korean government today announced the establishment of its own version of NASA, dubbed the Korea AeroSpace Administration (KASA), with what appears to be a focus on establishing a long term space program and using this to foster an aerospace commercial sector.

KASA was established under a special law passed by the National Assembly in January to unify government organizations in charge of space policy and projects. Based in Sacheon, South Gyeongsang Province, KASA has an annual budget of 758.9 billion won ($556 million) this year. The agency currently has around 110 employees and will eventually have a total of 293.

In March, the government established the 2024 Space Development Promotion Action Plan and set five major missions — including space exploration, space transportation, space industry, space security and space science.

In line with the government’s policy, KASA will establish a roadmap for Korea’s space exploration and plans to promote reusable launch vehicles, development of the country’s own global positioning system (GPS) and a lunar lander program. In particular, it plans to develop a lunar lander with a goal of landing on the moon in 2032, and to design and develop engines to enter the commercial launch service market.

A second South Korea news report quotes the head of this new agency as follows:

“Until now, the country’s space development projects have been led by the government,” Yoon Young-bin, KASA’s inaugural chief, said earlier. “The most important role of the space agency will be supporting the private sector to lead space development.”

He pointed out that the world’s space industry is moving toward the so-called “new space” era, where private companies are actively leading innovation in space technologies with more economic feasibility. “The global paradigm is shifting,” Yoon said, noting that top space companies, such as SpaceX, have developed reusable space rockets and launched a group of small satellites with capabilities similar to medium- and large-sized satellites.

If KASA maintains this approach, then South Korea’s future as a space power is bright. If instead KASA moves to control all space development, including the design and ownership of its rockets and spacecraft, then that program will be stifled, as America’s was by NASA for forty years after the 1960s space race.

China’s X-37B releases object in orbit

8:55 am

China’s copy of the U.S.’s military’s X-37B reusable mini-shuttle, dubbed Shenlong apparently released an object during its ongoing third orbital mission.

A new object (59884/2023-195G) has been cataloged associated with the Chinese CSSHQ spaceplane in a 602 x 608 km x 50.0 deg orbit. It seems to have been ejected about 1900 UTC May 24.

It is possibly this object is to test recapture maneuvers, as was done by during the mini-shuttle’s previous flight. It is also possible this release is preliminary to the end of the mission and the return of Shenlong to Earth. It is also possible it has a completely different purpose, since China has released practically no information about this spaceplane or any of its missions.

The present mission began a little more than seven months ago, releasing six small satellites a few days after launch. The previous two lasted two days and 276 days respectively. As with everything else, we have no idea how much longer it will remain in orbit.

North Korea notifies Japan of planned orbital launch

8:40 am

North Korea

North Korea today notified Japan that it plans a new orbital launch sometime between today and June 3, 2024, indicating several potential drop zones for the rocket’s lower stages.

It designated three areas where debris will fall — two west of the Korean Peninsula and the other east of the Philippines’ island of Luzon, according to the news outlet.

Pyongyang has made public a plan to launch three more satellites this year following its first military reconnaissance satellite launch in November.

The launch will apparently take place from North Korea’s Sohai spaceport on its west coast, and will fly over the country heading east. The payload will also likely be a reconnaissance satellite of some kind, similar to what the country launched in November 2023.

Harvard Corporation overides its pro-Hamas faculty; denies graduation to pro-Hamas rioters

1:43 pm

Harvard: where you get can get a shoddy education centered on hate and bigotry
Harvard: where you can spend a lot of money
being taught to hate Jews and support Hamas terrorism

In what might be signaling a major sea change at Harvard, the Harvard Corporation, which owns and runs the university, voted this week in support of an earlier decision by its administrative board to deny graduation to thirteen pro-Hamas demonstrators who are presently facing disciplinary action for their participation in the illegal take-over of university grounds for three weeks.

This decision was also a blunt rejection of a vote by the university’s faculty to override the administrative board’s decision and confer degrees to these protestors.

115 faculty members showed up to a meeting in which a decisive majority voted to confer degrees on the 13 seniors. The students were notified of disciplinary charges from the Harvard College Administrative Board just three days earlier.

I wonder if the financial problems Harvard is now facing influenced this decision by the corporation board. Applications to the school have dropped significantly, a number of big donors have cancelled their support for the university, and even worse, Harvard has a cash crunch. A bond offering intended to raise $2 billion this year raised far far less than expected.

Democratic Party voters fire Soros-backed DA in Portland

12:55 pm


Looters in downtown Portland in 2021

In a non-partisan primary on May 21, 2024, Portland voters rejected in large numbers the Soros-backed district attorney they had voted for only four years previously.

On Tuesday night, voters in Multnomah County, Oregon fired one-term George Soros-backed incumbent District Attorney Mike Schmidt.

Fox 12 called the race at approximately 9:30 pm local time with Schmidt’s opponent Nathan Vasquez leading 58 percent to 42 percent. In a non-partisan primary, if a candidate garners over 50 percent of the vote, they are declared the winner of the election but don’t take office until January 2025.

Though the primary election in Portland was “non-partisan” (in that no party affiliation for any candidate was listed) in this wholly Democratic Party-controlled stronghold there was no doubt that both candidates were from that party, and the vast majority of the voters were leftist Democrats as well.

Unlike Republican voters or Republican politicians, who like to whine but rarely do anything to get rid of bad apples, the Democrats in Oregon decided that Schmidt’s reign of disaster these last four years required a change. Schmidt had followed the leftist anti-police agenda of numerous other Soros-backed DAs nationwide.

NASA/Boeing/ULA confirm new June 1st launch date for Starliner

9:36 am

In a press briefing this morning officials from NASA, Boeing, and ULA confirmed the new June 1, 12:25 pm (Eastern) launch date for the first manned flight of Boeing’s Starliner manned capsule.

The officials provided a more detailed explanation of the helium leak in a valve that effects the capsule’s service module attitude thruster system, noting that it is not a design flaw but some specific issue in this particular valve. Because of this, they are confident the system can function safely even with the leak, which is relatively small.

However, the officials also noted that during their reviews in the past two weeks they discovered a new software issue in the spacecraft’s de-orbit engines that — under very unusual and unlikely circumstances — could actually cause those engines to fail to operate. They have figured out a work-around, whereby they fire the engines at a lower thrust in two stages rather than once.

Should the launch on June 1st be scrubbed for weather, they have back up dates on the next few days, though by June 4th ULA might have to swap out batteries on its Atlas-5 rocket that will require a longer stand down of several additional days.

SpaceX tentatively announces a June 5, 2024 Starship/Superheavy launch date

9:20 am

Starship/Superheavy flight profile
Click for original image at high resolution.

SpaceX today tentatively announced a June 5, 2024 launch date for the fourth Starship/Superheavy orbital test launch.

Before going into any details of the flight plan, as shown in the flight profile above, it is important to quote the first sentence in the announcement:

The fourth flight test of Starship could launch as soon as June 5, pending regulatory approval. [emphasis mine]

SpaceX has not yet gotten a launch permit from the FAA. It is likely it has inside information from the agency suggesting that permit will be issued by this date. It is also likely that SpaceX by making this announcement is applying pressure to the FAA to either get its paperwork done or waive the need so its red tape doesn’t delay the flight unnecessarily.

As for the flight itself, the flight profile is essentially the same as the previous test flight, with the Starship’s orbit designed for safety to bring it down in the Indian Ocean.

The fourth flight test turns our focus from achieving orbit to demonstrating the ability to return and reuse Starship and Super Heavy. The primary objectives will be executing a landing burn and soft splashdown in the Gulf of Mexico with the Super Heavy booster, and achieving a controlled entry of Starship.

To accomplish this, several software and hardware upgrades have been made to increase overall reliability and address lessons learned from Flight 3. The SpaceX team will also implement operational changes, including the jettison of the Super Heavy’s hot-stage following boostback to reduce booster mass for the final phase of flight.

All in all, this announcement is good news. SpaceX is ready to launch.

North Carolina university system repeals DEI policies

12:52 pm

Actually taking concrete stpes to end DEI
Actually taking concrete stpes to end DEI

Under pressure by its state legislature, which last year banned all diversity statements from state agencies, the Board of Governors for the North Carolina University (UNC) system voted today to repeal its Diversity, Equity, and Inclusion (DEI) policies that have encouraged discrimination against non-minorities within the system.

The new policy now requires UNC schools to “ensure equality of all persons & viewpoints,” and promote “nondiscrimination in employment practices.” It also mandates that all UNC schools comply with a series of amendments passed by the North Carolina General Assembly in the past year that limit what can be discussed or taught about race, racism and sex in government institutions.

…Schools in the UNC System are required to comply with the new policy by September 1. The proposal does not indicate how many DEI jobs might be impacted.

Earlier this month, the Board of Trustees for the University of North Carolina Chapel Hill passed a separate proposal to divert $2.3 million from DEI programs to public safety.

The new policy, which you can read here [pdf], is very clear that DEI racial quotas and poltical favorism must end. » Read more

Astronomers discover nearby Earth-sized exoplanet only slightly hotter than Earth

10:49 am

Using the TESS space telescope as well as a number of ground-based telescopes astronomers have discovered an Earth-sized exoplanet only 40 light years away that has a surface temperature estimated to be about 107 degrees Fahrenheit, assuming it has no atmosphere.

The host star, called Gliese 12, is a cool red dwarf located almost 40 light-years away in the constellation Pisces. The star is only about 27% of the Sun’s size, with about 60% of the Sun’s surface temperature. The newly discovered world, named Gliese 12 b, orbits every 12.8 days and is Earth’s size or slightly smaller — comparable to Venus. Assuming it has no atmosphere, the planet has a surface temperature estimated at around 107 degrees Fahrenheit (42 degrees Celsius).

At the moment however scientists do not yet know if the exoplanet has an atmosphere or not. Follow-up observations using the Webb Space Telescope are planned to find this out. Based on the data presently available, the exoplanet could either be like Venus, too hot to sustain life, or like Earth, cooler with water and an atmosphere and thus very habitable.

Gliese 12 b could therefore become one of the primary targets for the first interstellar missions once humanity begins such exploration.

Euclid releases new images and first science results

10:37 am

Euclid image
Click for original image.

The Euclid science team today released five early science images in connection of the publication of ten papers.

The picture to the right is one of those images, cropped, reduced, and sharpened to post here. From the caption:

In this image Euclid showcases NGC 6744, an archetype of the kind of galaxy currently forming most of the stars in the local Universe. Euclid’s large field-of-view covers the entire galaxy, capturing not only spiral structure on larger scales but also exquisite detail on small spatial scales. This includes feather-like lanes of dust emerging as ‘spurs’ from the spiral arms, shown here with incredible clarity.

Scientists are using this dataset to understand how dust and gas are linked to star formation; map how different star populations are distributed throughout galaxies and where stars are currently forming; and unravel the physics behind the structure of spiral galaxies, something that is still not fully understood after decades of study.

Euclid is a wide-field space telescope that has instruments that observe in both visible and near-infrared wavelengths. Its primary mirror at 1.2 meters is half the width of Hubble’s. More details about these early images and links to the new science results can be found here.

Unlike Hubble, it appears Euclid will not be used as a general observatory, at least initially. Its primary goal is to do a survey of one third of the sky, focusing on extragalactic sources outside the Milky Way. Once this is complete however it is possible the space telescope will be made available for other observations.

Psyche gets clean bill-of-health after completing six-month checkout since launch

10:13 am

Psyche's flight path to the asteroid Psyche
Psyche’s flight path to the asteroid Psyche.
Click for original image.

The probe Psyche has successfully completed its six-month checkout since its launch in October 2023 and is now using its ion engines to steadily increase its speed as it heads to a 2029 rendezvous with the metal asteroid Psyche.

The orbiter is now more than 190 million miles (300 million kilometers) away and moving at a clip of 23 miles per second (37 kilometers per second), relative to Earth. That’s about 84,000 mph (135,000 kph). Over time, with no atmospheric drag to slow it down, Psyche will accelerate to speeds of up to 124,000 mph (200,000 kph).

The spacecraft will arrive at the metal-rich asteroid Psyche in 2029 and will make observations from orbit for about two years. The data it collects will help scientists better understand the formation of rocky planets with metallic cores, including Earth. Scientists have evidence that the asteroid, which is about 173 miles (280 kilometers) across at its widest point, may be the partial core of a planetesimal, the building block of an early planet.

The graphic to the right shows the path Psyche will take to get to the asteroid.

SpaceX to FAA: Let us launch Starship/Superheavy before you complete the red-tape for the previous flight

9:55 am

Superheavy/Starship lifting off on March 14, 2024
Superheavy/Starship lifting off on March 14, 2024

According to the FAA, SpaceX has officially asked the FAA to allow it to launch the next Starship/Superheavy test orbital launch before the agency officially completes its mishap investigation into the previous flight in March.

In a statement sent to ValleyCentral, the FAA stated that on April 5, SpaceX requested the FAA make a “public safety determination” as part of the Starship flight test mishap. “If the FAA agrees no public safety issues were involved in the mishap, the operator may return to flight while the mishap investigation remains open, provided all other license requirements are met.”

With this modification in place, SpaceX would be able to launch the fourth Starship test flight while the mishap investigation of the third flight is still open.

When these requests are received, the FAA evaluates safety-critical systems, the nature of the consequences of the mishap, adequacy of existing flight analysis, safety organization performance and environmental factors, the statement added. The FAA stated it is reviewing the request and will be “guided by data and safety at every step of the process.”

What does this request tell us? First, as expected SpaceX has completed its own investigation into the March launch and installed the upgrades it considers necessary. Second, the FAA however has not, even though the FAA has absolutely no competence in this matter. It is merely retyping the SpaceX report.

Third, SpaceX now realizes that the FAA will not have finished that retyping when SpaceX is ready to launch sometime in the next three weeks. Rather than sit and wait, as it did on the previous two test launches, it wants the FAA to recognize reality and let it proceed. Why wait when the FAA is literally contributing nothing to the process?

Will the FAA do so? I suspect there are people in the FAA who would very much like to. I also know that there are others both in the FAA and higher up the command chain (mostly in the White House) that like the idea of slowing SpaceX down, mostly for petty political reasons. We should not be surprised if those higher ups use their clout and insist the FAA reject this request.

If so, the fourth test launch of Starship/Superheavy will likely be further delayed, though by how much is unclear. Shortly after the March test launch I predicted that the next flight would occur in the June/July timeframe, not early May as SpaceX was then predicting, and the delay will be mostly because of FAA red tape. It now appears that prediction will be correct.

Boeing/NASA now targeting a June 1, 2024 launch of Starliner

9:28 am

In a brief update posted today by NASA, the agency announced that Boeing, NASA, and ULA have a new 12:25 pm (Eastern) June 1, 2024 launch date for the first manned flight of Boeing’s Starliner capsule.

The announcement was incredibly obscure about what the issues are that have caused this additional week delay:

Work continues to assess Starliner performance and redundancy following the discovery of a small helium leak in the spacecraft’s service module. As part of this work, and unrelated to the current leak which remains stable, teams are in the process of completing a follow-on propulsion system assessment to understand potential helium system impacts on some Starliner return scenarios. NASA also will conduct a Delta-Agency Flight Test Readiness Review to discuss the work that was performed since the last CFT launch attempt on May 6, and to evaluate issue closure and flight rationale ahead of the next attempt, as part of NASA’s process for assessing readiness. The date of the upcoming Flight Test Readiness Review is under consideration and will be announced once selected.

It appears that engineers are worried the leak — which is linked to one of the attitude thrusters in the capsule’s service module — might impact the ability of Starliner to return to Earth safely. It also appears there is concern about the spacecraft sitting on the launchpad for more than a month, and an evaluation is on-going on whether this might be an issue as well.

I am guessing however. A more detailed explanation might be forth-coming after press update scheduled for 11 am (Eastern) tomorrow.

Two of Voyager-1’s four instruments resume science operations

Engineers have resumed getting science data from two of Voyager-1’s four instruments for the first time since in November 2023, when corrupted computer memory caused the spacecraft to send only incoherent data.

The plasma wave subsystem and magnetometer instrument are now returning usable science data. As part of the effort to restore Voyager 1 to normal operations, the mission is continuing work on the cosmic ray subsystem and low energy charged particle instrument. (Six additional instruments aboard Voyager 1 are either no longer working or were turned off after the probe’s flyby of Saturn.)

Engineers hope to begin getting good data the other two instruments in the next few weeks.
