Japanese startup enters the high altitude balloon space tourism business

9:35 am

A Japanese startup, Iwaya Giken, announced yesterday that it is building a two-person capsule that will carry two persons, a pilot and passenger, on high-altitude stratospheric tourist balloon flights for about $180K per ticket.

The company, Iwaya Giken, based in Sapporo in northern Japan, has been working on the project since 2012 and says it has developed an airtight two-seat cabin and a balloon capable of rising up to an altitude of 25 kilometers (15 miles), where the curve of the Earth can be clearly viewed. While passengers won’t be in outer space — the balloon only goes up to roughly the middle of the stratosphere — they’ll be higher than a jet plane flies and have an unobstructed view of outer space.

The company teamed up with major Japanese travel agency JTB Corp., which announced plans to collaborate on the project when the company is ready for a commercial trip. Initially, a flight would cost about 24 million yen ($180,000), but Iwaya said he aims to eventually bring it down to several million yen (tens of thousands of dollars).

No date for the first launch was mentioned. This company now joins two American balloon companies as well as a Spanish balloon company, all planning to offer rides to the edge of space.

Despite a complete lack of any customers, Spaceport America in New Mexico now plans to build a “reception center.”

9:28 am

The New Mexico Spaceport Authority has decided it needs to build another building at Spaceport America, even though that spaceport has seen no significant business in its almost two decades of operation, and has little indication of any future business to come.

The Spaceport Technology and Reception Center’s mission “will be to become the welcoming face to staff, visitors, and prospective customers visiting or working at Spaceport America. The proposed 30,000 square foot STARC building will be a multi-use facility; it will house the Spaceport’s core IT server center, staff offices and conference rooms, an Auditorium, food preparation and dining area, virtual experience center, and 2nd and 3rd floor lounge and viewing areas,” according to a request for proposals (RFP) issued by the New Mexico Spaceport Authority (NMSA). “The new building will provide modern, comfortable work and meeting spaces for NMSA staff and a means to receive, entertain and educate groups of visitors and/or potential customers,” the document added.

The article goes on to detail how NMSA has spent millions of tax dollars for years, with the promise of billions of revenue from space launches and thousands of local jobs, all of which have turned out to be pie in the sky. Other than Virgin Galactic, which remains a very questionable customer, no major rocket companies have shown any interest in launching from this spaceport.

To propose spending more on another building that will likely sit empty most of the time is absurd. As the article notes, New Mexico has many much more compelling issues to spend its taxpayer money. This boondoggle should be shut down.

A lunar lava avalanche three miles wide and one mile long

A lunar lava avalanche three miles wide and one mile long

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken October 16, 2016 and released today by the Lunar Reconnaissance Orbiter (LRO) science team. It shows a three-mile-wide unnamed crater that impacted on the rims of two other lunar impacts, one larger but the other monumental.

The trio of impact events that resulted in this spectacular corner of the Moon occurred over nearly four billion years of lunar history; first, the Orientale basin (>3.7 billion years), Lowell W (one to three billion years), and finally, this unnamed crater (likely <100 million years).

The Orientale Basin is about 500 miles wide, and is one of the most distinct large features on the lunar surface, a gigantic bowl with three concentric rings surrounding it. Because it is near the eastern limb of the near side, it wasn’t until the space age before a good overhead view of this major lunar geological impact basin was seen. Lowell W is about 11 miles wide.

The overview map below shows the context between Lowell W and this small crater, with the yellow lines indicating the area covered by the picture above.

Russians release image of coolant system hole in Progress

1:47 pm

Comparing holes in Soyuz and Progress spacecraft

Roscosmos officials today released a close-up image taken on February 17, 2023 of what they think is the hole in the Progress freighter that caused a leak in its coolant system on February 11th.

The picture was taken shortly after the freighter undocked from ISS to be de-orbited over the Pacific. To the right is a comparison of pictures taken of that Progress hole and the hole that occurred in December on the Soyuz spacecraft docked to ISS. The comparison was first created by this Twitter user but rearranged by me to post here. The red circle in the bottom image marks what the Russians identify as the Progress hole. The top image shows the hole that caused an almost identical leak in a Soyuz capsule in December. The Russians say the Progress hole is about 12 millimeters in diameter, and to their mind was caused “by an external influence,” same as the Soyuz hole.

This conclusion however is suspect. If you look at the best resolution version of the picture of the Progress hole (available here), there appears to be material surrounding the hole, as if the hole broke from the inside, not from an outside impact. (Because the resolution is poor, however, this conclusion is uncertain.)

More telling is that, as both pictures show, the two holes are almost in the exact same place on these two spacecraft. As noted by the Twitter user who first made this picture comparison, “I can’t even calculate the odds of 2 spacecraft being struck in almost the same place, within weeks of each other.”

That the Soyuz leak caused so much staining and the Progress leak has none is also puzzling.

Were these leaks both caused by the impact of a micrometeoriod or piece of space junk, as the Russians now claim? Or was one by sabotage or sloppy production work on the ground? Or were both? One impact might make sense, but two at almost the same spot? It defies logic or the percentages for two impacts so similar to occur so close together in time.

Sabotage however in the same area is very conceivable, especially considering that the Russians have never explained the cause of the hole that was drilled in a Soyuz capsule in 2018, a hole that was drilled and then patched, before launch.

Pushback: Home appraiser sues professors who called him racist without evidence

12:02 pm

Mott (l) and Connolly, eager to defame whites
Mott (l) and Connolly, eager to use race to
defame an innocent white man

Bring a gun to a knife fight: A home appraiser, Shane Lanham, who was publicly accused by two Johns Hopkins professors, Nathan Connolly and Shani Mott, of being a bigot and racist by valuing their home less because they are black, has now filed a countersuit, noting that the accusation was based on data so faulty “a first-year undergraduate” would immediately reject it.

[T]heir claims would fail to pass basic academic muster if treated as scholarship, Lanham argued in his counterclaim, which includes a suit for defamation. The racism claims achieved national coverage such as in ABC News. The resulting allegations have harmed Lanham’s business and reputation, according to the lawsuit.

“Dr. Connolly and Dr. Mott’s ill-conceived ‘experiment’ involving different appraisers, a seven-month gap, and intervening changes in market conditions would not withstand even basic scrutiny in the serious academic environment in which they work,” Lanham’s counterclaim stated. The lawsuit noted that the professors “failed to disclose the sale of the similar house next door to their home that sold only a month after Mr. Lanham and 20/20 Valuations’ appraisal for $7,000 less than the amount of the appraisal.”

You can read Lanham’s countersuit here [pdf]. He is requesting, at a minimum, $250K in compensatory damages and $250K in punitive damages.

This story began when Connolly and Mott asked Lanham (who is white) and his company, 20/20 Valuations, to appraise their house. When they were unhappy with his appraisal, they decided to get another appraisal, but this time do what they themselves called a ““whitewashing experiment.” For the second appraisal they removed all evidence that a black family owned the house, to the extent of having a white friend present himself as the owner instead. The second appraisal, done months later, came up with a higher price.

Solar Orbiter captures Mercury crossing in front of the Sun

Solar Orbiter spots Mercury in front of the Sun
Click for full movie.

The European probe Solar Orbiter successfully filmed Mercury as it crossed in front of the Sun — from the spacecraft’s perspective — on January 3, 2023.

The transit was captured by several different instruments on Solar Orbiter, as shown at the link. The picture above is a screen capture from the short movie made by its Extreme Ultraviolet Imager. The black disk is Mercury, moving from the left to the right. In the background the limb of the Sun can be seen, with a distinct feature flaring out from that limb.

For Solar Orbiter, this particular transit offered a valuable chance to calibrate the instruments. “It is a certified black object travelling through your field of view,” says Daniel Müller, Solar Orbiter Project Scientist at ESA. Thus, any brightness recorded by the instrument within Mercury’s disc must be caused by the way the instrument transmits its light, called the point spread function. The better this is known, the better it can be removed. So be studying this event, the quality of the Solar Orbiter data can be ever further improved.

If the transit also produced some spectacular images, so much the better.

VLT takes picture of exoplanet

9:20 am

VLT's picture of exoplanet
Click for original image.

The ground-based Very Large Telescope (VLT) in Chile has successfully taken a picture of an exoplanet four to six times larger than Jupiter that is circling its star at about the same distance as Saturn.

That picture, cropped to post here, is to the right. Other data from other observatories had suggested the star AF Leporis, 87.5 light years away, might have an exoplanet, so astronomers decided to focus VLT on it to see if it could spot it.

AF Leporis is about as massive and as hot as the sun, ESO wrote in the statement, and in addition to its one known planet the star also has a disk of debris similar to the solar system’s Kuiper Belt. AF Leporis is, however, much younger than the sun. At 24 million years old, it is about 200 times younger than our star. This young age makes AF Leporis and its planetary system especially intriguing for astronomers as it can provide important insights into the evolution of our own solar system.

To snap this picture, the VLT had to use adaptive optics to smooth out the fuzziness produced by the Earth’s atmosphere, while also blocking out the star’s own light (as shown by the black disk in the image).

China’s continued silence about Zhurong suggests Mars rover is dead

9:05 am

Zhurong's ground-penetrating radar data
The data from Zhurong’s ground-penetrating radar instrument.

Overview map
Zhurong’s final location is somewhere in the blue circle.

China’s continued silence about Zhurong — which should have come out of hibernation sometime in late December-early January — suggests the Mars rover did not survive the Martian winter, which this year was also lengthened near the end by some additional dust storms.

Zhurong went into hibernation in May 2022, at the start of winter, with plans to awaken in December. Like the helicopter Ingenuity and the lander InSight, it depends on solar power, and had to contend with a very relatively severe winter dust season this Martian year.

Even though the Chinese press has loudly touted Tianwen-1’s first two years in Mars orbit, it has made little or no mention of Zhurong, a silence that is deafening.

The silence is also foolish, because China has nothing to be ashamed of concerning Zhurong. The mission was only supposed to operate for 90 days. Instead it lasted more than a year, traveling much farther than planned. Most important, the data from its radar instrument (shown above) showed that, at this location at 25 degrees north latitude, there is no underground ice to a depth of 260 feet. That data confirmed that the Martian equatorial regions below 30 degrees latitude are very dry, with any underground ice existing rarely if at all. The icy regions above 30 degrees latitude do not appear to extend much farther south than that latitude.

Today’s blacklisted American: Georgetown Law School tried to destroy a student simply because he asked questions about its COVID jab and mask policies

Georgetown Law School's Dean Bill Treanor
Dean Bill Treanor: He uses 1984 as
his instruction manual

They’re coming for you next: When student William Spruance gave a speech challenging the COVID jab and mask policies at Georgetown Law School, which required for example masks on students but not on teachers, university officials attempted to not only cancel him from the college, they tried to destroy him entirely.

They not only suspended him from the campus (thus preventing him from attending classes), they demanded he undergo a psychiatric evaluation while also waiving his right to medical confidentiality. On top of this, they threatened to report him to state bar associations if he did not cooperate fully.

The story at the link, written by Spruance, has a lot more horrifying nuance. Rather rehash it completely, I strongly advise my readers to go there and read it all. This quote though justifies fully Spruance’s reasonable skepticism of Georgetown’s irrational Wuhan flu policies:

Splashed lava from a Martian impact

Splashed lava from a Martian impact
Click for original image.

Almost always it is impossible to understand a high resolution image from Mars Reconnaissance Orbiter (MRO) unless you also take a wider view. Today’s cool image to the right, rotated, cropped, reduced, and sharpened to post here, is a perfect example.

Taken on January 6, 2023, it shows what the science team labeled as a “rocky deposit on crater floor.” To my eye however none of this appeared tremendously rocky. Instead, what I saw was a curved and layered flow feature whose ancient age was suggested by the many later craters scattered across its surface.

Still, its origin was unclear. It isn’t ice, not only because of its apparent resistance from disturbance from those later crater impacts but because it is located at about 20 degrees north latitude, in the dry equatorial regions of Mars. If lava, what is its source? As I noted, a wider look was necessary to answer that question.

For the 4th time Curiosity’s drill fails to penetrate marker layer

9:44 am

Failed drillhole by Curiosity in marker layer
Click for original image.

For the fourth time this past weekend Curiosity’s drill was unable to penetrate the hard rock of what scientists have labeled “the marker layer”, a distinct feature seen at approximately the same elevation at many places on the flanks of Mount Sharp on Mars.

The image to the right, cropped and reduced to post here, shows that the drill was once again only able to drill a eighth to a quarter inch, not enough to gather samples for testing.

This was our fourth attempt to drill this marker band, and we gave it our best shot from both a geology and engineering perspective. Unfortunately these rocks do not want to cooperate – they’re hard and they weather into resistant and recessive beds which make them very challenging to drill. So the team made the difficult decision to get back on the road, without a drill sample from this location

India’s Chandrayaan-3 lunar lander/rover passes radiation testing

8:59 am


Click for interactive map.

According to India’s space agency ISRO, its next lunar lander/rover, Chandrayaan-3, has successfully passed testing to make sure it can function without issues in the harsh electromagnetic environment of space.

Magnetic Interference/ Electro – Magnetic Compatibility) test is conducted for satellite missions to ensure the functionality of the satellite subsystems in the space environment and their compatibility with the expected electromagnetic levels.

The spacecraft, which will carry a rover to the Moon’s south pole regions (the red dot on the map to the right), is tentatively scheduled for launch anywhere from June to the end of ’23, depending on the news story you read.

First orbital tug from the startup Launcher fails shortly after deployment

1:18 pm

The first orbital tug, dubbed Orbiter SN1, of the startup company Launcher failed shortly after deployment from a SpaceX Falcon 9 rocket on January 3, 2023.

The vehicle communicated with a ground station on its first scheduled pass after deployment while on battery power. “We also communicated with the vehicle for the duration of expected battery life,” the company said.

However, the Hawthorne, California-based company said the spacecraft could not get into the proper attitude so that its solar cells could generate power, which it blamed on “an orientation control issue caused by a fault in our GPS antenna system.” That, in turn, kept Orbiter from deploying its satellite payloads.

The tug was carrying payloads from eight customers, four of which were satellites to be deployed while the others would remain on the tug, using it as the base of operations.

The company presently has plans to launch upgraded tugs on two different Falcon 9 launches, in June and October respectively.

Inspection of leaking Progress after undocking detects no obvious damage

1:10 pm

After undocking the Progress freighter from ISS yesterday, Russian astronauts on the station rolled it so that all sides of its service module could be photographed and inspected in the hope of spotting the leak in its coolant system that sprung on February 11th.

No visual damage has been detected at the Progress MS-21 spacecraft after it undocked from the International Space Station. “After the Progress MS-21 cargo spacecraft undocked from the International Space Station’s Poisk mini-research module, footage was made of its exterior surface and no visual damage was detected,” the statement [from Roscosmos] reads.

Initially the Russians postponed its de-orbit as they considered the idea of redocking the freighter to another port on the Russian half of ISS in order to inspect it more closely, but eventually they decided to fore-go that plan and de-orbit it on February 19th, one day later.

In watching the live stream of the undocking and the roll maneuver, I thought I saw a partial reddish-orange stain, similar to the stain around the hole that occurred in the Soyuz capsule in December, but it was mostly hidden behind other equipment and the Russians seemed to not consider this significant.

  • Damaged Progress to undock from ISS shortly

    • Live stream is here, scheduled to go live around 6:15 pm Pacific. Following undocking the freighter will be maneuvered so that the leak in its coolant system on its service module can be photographed.

 

  • U.S. military is loosening its rules for bidding on its launches

    • The language in the screen capture at the link is typical bureaucratic blather, but the bottom line is that the military is no longer limiting bidding on launch contracts to just SpaceX and ULA, a foolish program I have begging the military to abandon for years. At this point they will let others bid on missions that are less risk tolerant. Expect with time this policy to loosen even more, as more competition can only save the military money, while providing it more redundancy and capability.

“Nice job you got here. Shame if something happened to it.”

They’re coming for you next: Professor Richard Lowery is now suing the University of Texas at Austin (UT-Austin) for its attempts to silence him, including threatening his job, cutting his pay, and monitoring his speech, actions instigated against Lowery because he was publicly critical of the university’s racist “diversity, equity, and inclusion” policies as well as the university’s efforts, led by its president Jay Hartzell, to insert political propaganda into its courses.

Lowery is being represented by the Institute for Free Speech, which filed his lawsuit [pdf] on February 8, 2023.

The campaign [against Lowery and his allies at the university] started by pressuring Carlos Carvalho, another professor of business at the UT McCombs School who is also the Executive Director of the Salem Center for Public Policy, an academic institute that is part of the McCombs School. Lowery is an Associate Director and a Senior Scholar at the Salem Center and reports to Carvalho.

A galaxy’s structure of gas and dust, as seen in the infrared by Webb

10:04 am

NGC 1433 as seen in the infrared
NGC 1433 as seen in the infrared. Click for original image.

Scientists have now released 21 papers on the gas and dust structures in nearby galaxies, based on infrared images from the Webb Space Telescope, used in collaboration with other telescopes looking in other wavelengths.

The largest survey of nearby galaxies in Webb’s first year of science operations is being carried out by the Physics at High Angular resolution in Nearby Galaxies (PHANGS) collaboration, involving more than 100 researchers from around the globe. The Webb observations are led by Janice Lee, Gemini Observatory chief scientist at the National Science Foundation’s NOIRLab and affiliate astronomer at the University of Arizona in Tucson.

The team is studying a diverse sample of 19 spiral galaxies, and in Webb’s first few months of science operations, observations of five of those targets – M74, NGC 7496, IC 5332, NGC 1365, and NGC 1433 – have taken place.

The image to the right is Webb’s infrared image of NGC 1433, estimated to be 46 million light years away. The bright areas extending outward in the spiral arms are believed to be star-forming regions. From the caption:

At the center of the galaxy, a tight, bright core featuring a unique double ring structure shines in exquisite detail with Webb’s extreme resolution. In this case, that ‘double ring’ is actually tightly wrapped spiral arms that wind into an oval shape along the galaxy’s bar.

NGC 1433 is a Seyfert galaxy, which are typically relatively close to Earth and has a supermassive black hole at the center eating material at a high rate. The brightness and lack of dust in the MIRI image of NGC 1433 could hint at a recent collision with another galaxy.

When comparing Webb’s infrared view with Hubble’s optical view, taken in 2014 and found here, the differences are definitely striking. Webb sees the gas and dust that is dark in Hubble’s images, while Hubble sees things at much higher resolution and thus sees more fine detail.

China today released another set of data from the instruments on the Chang’e-4 lander, which landed on the far side of the Moon on January 3, 2019, bringing with it China’s Yutu-2 rover.

The datasets include 3,991.1 MB of 803 data files obtained by the four scientific payloads on the Chang’e-4 lander and rover between December 26, 2021 and January 10, 2022.

The data was posted on the official website of the Lunar and Planetary Data Release System, though none of the press reports from multiple China’s state-run press sources include it. All are simply the same three paragraph story, word for word. That site however is here, though it is entirely in Chinese and the English pages fail to load.

For only 7th time, searchers find meteorite immediately after fall

8:57 am

For only 7th time, searchers on February 15th found a fragment of a meteorite that had only fallen to Earth three days before, and was furthermore only discovered mere hours before it entered the Earth’s atmosphere.

From the tweet of the discoverers:

FRIPON/Vigie-Ciel finds a fragment of asteroid 2023CX1 in Seine Maritime!!! The discovery was made by Loïs Leblanc, an 18-year-old student, part of the field research team.

Vigie-Ciel (“Sky Watchers”) and FRIPON are a volunteer project that searches for meteorites. The asteroid itself was discovered by Hungarian astronomer Krisztián Sárneczky while doing routine survey scan for near Earth asteroids.

The find was the second time Sárneczky has spotted an asteroid just hours before it broke apart in Earth’s atmosphere as a fireball, following an incredible find in March 2022.

By finding meteorites this quickly after arrival scientists get a more pristine sample, since the asteroid has not been exposed to the Earth’s environment for any extended length of time.

First launch of Japan’s H3 rocket aborts at T-0

8:25 pm

In its first attempt to launch its new H3 rocket today the rocket’s main liquid-fueled engines ignited, but then the two strap-on solid rockets failed to ignite at T-0, causing that main engine to shut down to protect the rocket and payload.

I have embedded the live stream below, cued to about T-39. At the end of the broadcast the rocket appeared in good condition, though it was still unclear what the caused the problem.

At the moment there is no word when JAXA, Japan’s space agency, will attempt another launch. The H3 is years behind schedule, and was developed in the hope it would be more efficient and cost less to launch than the H2A rocket Japan presently uses.

Ingenuity completes 43rd flight on Mars, the longest in almost a year

5:20 pm

Overview map
Click for interactive map.

The Mars helicopter Ingenuity today successfully completed its 43rd flight on Mars, traveling 1,280 feet for 2 minutes and 26 seconds.

The green dot on the map to the right marks Ingenuity’s position before the flight, with the green lines marking the approximate direction and distance flown. The Perseverance/Ingenuity team has not yet updated its interactive map, so the precise landing spot is not yet available.

This flight was the helicopter’s longest since April 2021, just before the onset of the long six-month-long Martian winter. At that time Ingenuity completed its 28th flight, traveling 1,371 feet. Since then engineers struggled to keep Ingenuity alive during the dark winter, a task made more difficult due to an unexpected higher winter dust storm season.

Winter however is over, the helicopter is now fully charging with no problem, and has new flight software that allows it to go higher and over rougher terrain. In fact, like the last flight, Ingenuity flew farther and longer than planned, as it had been programmed to go 1,235 feet for 2 minutes and 17 seconds. That extra 45 feet and 9 seconds were likely used by the helicopter to locate a safe landing spot.

For perspective, Ingenuity’s total mission was originally planned to last only 30 days, and complete about a half dozen test flights merely to prove the concept of flight on Mars was possible. It has now lasted two years, completed 43 flights, and traveled almost five and a half miles. An amazing engineering achievement by JPL’s engineering team.

They’re coming for you next: Despite a civil rights complaint filed back in November 2022 against Rhode Island’s Providence Public School District for offering only “educators of color” a $25,000 loan forgiveness, that school district has continued to offer this discriminatory and racist benefit to only certain races, including a hiring event that occurred just yesterday.

You can read the complaint here [pdf], filed by the Legal Insurrection Foundation. According to this news report a week ago, the federal Office of Civil Rights “…was making a formal referral of the Complaint to the Equal Employment Opportunity Commission (EEOC) for investigation. EEOC already has assigned an investigator to the case.”

Yet, despite its clear bigoted illegality and the existence of a legal action against it, the Providence Public School District doesn’t care. » Read more

The endless volcanic ash of Mars' Medusae Fossae Formation
Click for original image.

Cool image time! The picture to the right, cropped, reduced, and enhanced to post here, was taken on January 6, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows a small but typical area of the Medusae Fossae Formation, what is thought to be the largest volcanic ash deposit on Mars.

The picture itself was a “terrain sample,” taken by the MRO science team not as part of any specific research but to fill a gap in the camera’s schedule so as to maintain its temperature. The terrain itself looks like a field of sand that someone had run a fine comb across. In this case, the comb was the winds of Mars, prevailing from the southeast to the northwest. The crescent-like divots in the picture’s lower right are probably caused by some hard underground feature that the winds cannot blow away. Instead, it blows around, like water in rapids flowing around a rock, and takes the ash with it as it does so.

NASA outlines its expected needs as a space station customer

9:10 am

NASA has now published an updated detailed specification of what it will want to do on the four private space stations being built to replace ISS.

NASA published two white papers Feb. 13 as part of a request for information (RFI) for its Commercial Low Earth Orbit Destinations effort to support development of commercial stations. The documents provide new details about how NASA expects to work with companies operating those stations and the agency’s needs to conduct research there.

One white paper lists NASA’s anticipated resource needs for those stations, including crew time, power and volume, broken out for each of the major agency programs anticipated to use commercial stations. Companies had been seeking more details about NASA requirements to assist in the planning of their stations.

,,,The second white paper outlines the concept of operations NASA envisions for its use of commercial space stations. The 40-page document described in detail what it expects from such stations in terms of capabilities, resources and operations, as well as what oversight the agency anticipates having.

At the moment NASA has contracts with four different space station companies or partnerships, Axiom, Blue Origin, Nanoracks and Northrop Grumman, each of which is building its own station. Because NASA will initially be the biggest customer for these stations its requirements will help shape those stations significantly, which is why this information is of critical importance for the private companies.

At the same time, NASA is not dictating specific designs. The agency remains the customer, buying time on private facilities that will be owned privately and be free to sell their product to others. Thus, the designs of these stations might not match exactly what NASA desires, since even now there are other customers interested in buying space station time and space.
