Michael Knowles – Celebrating Columbus

6:01 pm

An evening pause: On this day when all should be celebrating Christopher Columbus and his willingness “sail beyond the sunset,” to use a phrase from Tennyson, this short video give us an accurate picture of the man, his times, and his achievements. It also puts the lie to the bigoted, hateful, leftist slanders that have been used in recent years to poison his legacy.

Note that I got this video from Rumble. I ask all who wish to suggest evening pauses to consider searching on Rumble and Vimeo, so that we are less dependent on YouTube. The Google company needs to feel some competitive pressure.

Ancient fossil river in the very dry equatorial regions of Mars

1:27 pm

Inverted Channel on Mars
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, was taken on August 29, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label an “inverted channel in Arabia Terra,” a small example of the more than 10,000 miles of fossilized rivers in this region on Mars that scientists have identified using MRO.

They are made of sand and gravel deposited by a river and when the river becomes dry, the channels are left upstanding as the surrounding material erodes. On Earth, inverted channels often occur in dry, desert environments like Oman, Egypt, or Utah, where erosion rates are low – in most other environments, the channels are worn away before they can become inverted. “The networks of inverted channels in Arabia Terra are about 30m high and up to 1–2km wide, so we think they are probably the remains of giant rivers that flowed billions of years ago. [emphasis mine]

Since this fossilized river is located at 11 degrees north latitude, smack in the middle of the dry equatorial regions of Mars, it has certainly been a dry desert for a very long time. You can see how barren the terrain appears by looking at the wider view afforded by MRO’s context camera below.

Weather delays New Shepard’s Shatner launch one day

8:56 am

Capitalism in space: Because of high winds predicted for tomorrow, Blue Origin has delayed its next suborbital flight of New Shepard, carrying four private citizens including William Shatner, for one day to October 13th.

The launch is scheduled for 9:30 am (Eastern), with live coverage beginning at 8 am (Eastern) on Blue Origin’s website. Be warned, however. If you watch with the sound on you will likely have to listen to a lot of hype and blather from the company’s announcers, who routinely can’t keep their mouths shut and have to tell us over and over and over again how “spectacular” and “breath-taking” and “historic” this all is.

If they do pause in their hyperbole, however, listening to Shatner during the flight will likely be worth it. The man has wit and knows how to use it.

OneWeb to use India’s rockets for satellite launches

8:44 am

Capitalism in space: OneWeb today announced that it has signed a deal with India to use its rockets for satellite launches.

Low Earth orbit (LEO) satellite communications company OneWeb has announced its plans to collaborate with the commercial arm of the Indian Space Research Organisation (ISRO), NewSpace India Limited (NSIL), to utilise indigenously built Polar Satellite Launch Vehicle (PSLV) and the heavier Geosynchronous Satellite Launch Vehicle (GSLV-MkIII) as likely platforms to launch OneWeb’s satellites in India from next year.

This is not good news for either Russia or Arianespace. Up to now these entities pretty much were launching all of OneWeb’s satellites. Now some of that business is being shifted to India.

The deal was revealed at a press conference that announced the formation of an Indian commercial trade organization, the Indian Space Association (ISpA), that partnering with the government will use the government’s space assets to develop private commercial space resources.

The Indian Space Association (ISpA) will be headed by Jayant Patil, senior executive vice president – Defence, L&T-NxT as its chairman, and Bharti Airtel’s chief regulatory officer Rahul Vatts as its vice-chairman, while Lt Gen. A.K. Bhatt (Retd.) has been appointed as the director-general of the association.

Among its early members include Bharti Airtel, Larsen & Toubro, Nelco (Tata Group), OneWeb, Mapmyindia, Walchandnagar Industries and Ananth Technology Limited.

Bharti is the company that invested $500 million to bring OneWeb out of bankruptcy, partnering with the United Kingdom.

The key question is whether these private companies will invest in developing private rockets, or will simply continue to launch using ISRO’s rockets. Based on this announcement, it appears the latter, but since the whole goal here of the Modi government of India appears to be to encourage a private sector, this could soon change.

As expected, Pluto’s atmosphere is freezing as its orbit takes it from the Sun

10:48 am

Data from ground-based telescopes has now confirmed that Pluto’s nitrogen atmosphere has begun it annual winter freeze out as the planet’s somewhat elliptical 248-year-long orbit takes it away from the Sun.

For about 25 years, Pluto has been moving farther and farther away from the sun, so its surface temperature has been going down. And with these recent observations, the researchers found evidence showing that Pluto’s atmosphere is actually refreezing back onto its surface as the dwarf planet gets colder and colder. Pluto is so far from the sun that, as time goes on, it will get distinctly farther away (and colder) before getting closer to the sun in other regions of its immense orbit.

The astronomers were able to detect this refreezing by observing the planet as it eclipsed a star in 2018.

New Horizons discovers two binary asteroids in Kuiper Belt

10:32 am

Overview map
Click for full map.

As New Horizons traveled from Pluto to the asteroid Arrokoth in 2018, scientists used it to take images of the relatively nearby asteroids that it was passing, and found that two of those asteroids appeared elongated.

[T]he team fit the shapes with a two-body model: two asteroids in a tight orbit. Even though the individual rocks weren’t resolved, the modeling showed that two bodies were better able to explain the elongation, as well as the brightness seen. The model for 2011 JY31 had two 50-km-wide objects nearly 200 km apart, while for 2014 OS393, the model had slightly smaller bodies (30 km across) that orbited each other 150 km apart.

The map, cropped and further annotated by me, shows New Horizons’ path during this time period, with the two binary asteroids indicated in blue.

This data, combined with the double lobe shape of Arrokoth (formerly named Ultima Thule), strongly suggests that it was not unusual for these primitives asteroids in the early solar system to coalesce from comparably sized partners.

Update on Boeing’s investigation into Starliner valve issue

10:10 am

NASA yesterday issued an update on Boeing’s investigation into Starliner valve issue, noting that progress is being made.

Boeing has demonstrated success in valve functionality using localized heating and electrical charging techniques. Troubleshooting on the pad, at the launch complex, and inside the Starliner production factory at Kennedy Space Center has resulted in movement of all but one of the original stuck valves. That valve has not been moved intentionally to preserve forensics for direct root cause analysis.

Most items on the fault tree have been dispositioned by the team including causes related to avionics, flight software and wiring. Boeing has identified a most probable cause related to oxidizer and moisture interactions, and although some verification work remains underway, our confidence is high enough that we are commencing corrective and preventive actions. Additional spacecraft and component testing will be conducted in the coming weeks to further explore contributing factors and necessary system remediation before flight.

…Boeing has identified several paths forward depending on the outcome of the testing to ultimately resolve the issue and prevent it from happening on future flights. These options could range from minor refurbishment of the current service module components to using another service module already in production. [emphasis mine]

The announcement also confirmed that the next launch attempt of the unmanned demo mission is now being targeted for “the first half of 2022, pending hardware readiness, the rocket manifest, and space station availability.”

The highlighted words raise a very serious question. How is it possible for “oxidizer and moisture interactions” to cause this problem now on Starliner, when the environmental conditions at Cape Canaveral for spacecraft have been understood for better than sixty years? Though this problem might have uncovered a previously undetected fundamental engineering issue related to valves, I am very skeptical. It seems more likely that some quality control issue occurred during this capsule’s assembly. That they are considering using a different Starliner capsule for the demo flight strongly confirms this, suggesting again that the valve issue is not systemic to all valves but is specifically linked to the assembly of this capsule.

If this speculation is correct, it suggests there are some some very disturbing quality control problems in Boeing’s Starliner design and assembly processes. First they missed about sixty software issues that forced the premature landing of the capsule in the first demo flight, issues that should have been fixed during design and construction. Now it appears they have discovered assembly problems with the capsule’s valves, and only did so mere hours before launch.

Boeing has got to get these issues fixed, or it is going to have a serious public relations problem garnering private customers outside NASA once Starliner begins commercial flights.

Data from Perseverance confirms Jezero Crater once held a lake

6:52 am

figure 5 from paper showing ancient lake in Jezero Crater

According to a newly published paper, the data obtained by the rover Perseverance has confirmed and refined what orbital data has suggested, that Jezero Crater once held a lake. From the abstract:

We analyze images taken by the rover in the three months after landing. The fan has outcrop faces that were invisible from orbit, which record the hydrological evolution of Jezero crater. We interpret the presence of inclined strata in these outcrops as evidence of deltas that advanced into a lake. In contrast, the uppermost fan strata are composed of boulder conglomerates, which imply deposition by episodic high-energy floods. This sedimentary succession indicates a transition, from a sustained hydrologic activity in a persistent lake environment, to highly energetic short-duration fluvial flows.

In other words, the crater first held a lake, which as it slowly dried out was periodically renewed by flash floods. The distinct delta of material that made Jezero Crater the prime landing site was apparently formed during the period when the lake existed. The conditions that caused the subsequent flash floods is as yet not been determined, though it likely is related to the red planet’s long term evolution.

The image above, figure 5 from the paper, shows the inferred lake in that early history. The red cross marks Perseverance’s landing site.

This data reinforces the fundamental scientific mystery of Mars. It shows evidence that liquid water once flowed on the surface of Mars, even though other long term data of the planet’s history says the Martian atmosphere has been too thin and too cold to allow that to happen. There is evidence that the atmosphere might have once been thicker, but no computer model or theory has been able to produce a time when it was warm enough.

Astronauts name next new Dragon capsule to fly “Endurance”

6:33 am

The astronauts who will fly on SpaceX’s new Dragon capsule at the end of this month have named it “Endurance”, for a variety of reasons.

“First off,” said [mission commander Raja Chari], “it is a tribute to the tenacity of the human spirit as we push humans and machines farther than we ever have, going both to stay and extended stays in low Earth orbit, opening it up to private companies and private astronauts and knowing we will continue our exploration to go into even further and continue.”

“Also, it is a nod to the development teams, production teams [and] training teams that got us here, who have endured through a pandemic,” he said.

…Lastly, there was a historical connection — one that spoke to the mission they are about to embark on and the skills it will take for it be successful.”I go straight to the Shackleton voyage,” said Marshburn, referring to Ernest Shackleton’s 1914 expedition to cross Antarctica. Shackleton’s ship, the Endurance, was trapped in ice and he and his crew endured months of hardship before being rescued.

SpaceX’s fleet of manned capsules now includes Endeavour, Resilience, and Endurance. A fourth capsule is scheduled to fly in April ’22, but no name as yet has been announced.

Chang’e-5 lunar samples youngest ever found

6:28 am

The uncertainty of science: The lunar samples returned to Earth by China’s Chang’e-5 lander have been found to be the youngest ever found, about two billion years old and a billion years younger than any other previous sample, with a composition that confirms the material in this area was also the youngest volcanism so far found on the Moon.

Collecting young lunar rocks was one of the main objectives for the Chang’e-5 mission, which sent a lander to the Moon in December 2020. The craft grabbed 1.7 kilogram (4 pounds) of lunar regolith from the vast volcanic plain of Oceanus Procellarum and flew back to Earth within the month. Observations from lunar orbit had identified this mare to be younger than other areas by its paucity of craters, which suggested that the lava there had flowed more recently. By dating the samples returned to Earth, the scientists confirm that volcanism occurred later in Oceanus Procellarum than other areas of the Moon.

Many news stories are claiming that the young age of these samples is a surprise, but this isn’t true. It was expected, as the quote above indicates.

However, the composition of the rocks did not match what was expected. Though created by volcanism, it appears the material did not have kind of composition seen in other lunar volcanic rocks. This is now a new puzzle for scientists.

SpaceX to double its fleet of reusable manned Dragon capsules

11:07 am

Capitalism in space: Based on the launch plans now announced, SpaceX will double its fleet of reusable manned Dragon capsules from two to four.

The upcoming October 30th launch of a new crew to ISS will use a new as yet unnamed Dragon capsule. In addition, the April ’22 flight will use another new capsule.

The four previous manned Dragon flights used Resilience (twice) and Endeavour (twice).

At the moment SpaceX appears to be reserving Resilience for non-ISS tourist flights. It was used in September in this way for the Inspiration4 private mission, and I expect it will be used again for the December Space Adventures tourist flight. For these non-ISS flights SpaceX removed Resilience’s docking port, replacing it with a large window.

The result will be that a private American company will own its own fleet of manned spaceships, three of which can dock with ISS, and one of which aimed at just orbiting the Earth. That’s a private company, not a nation. And that private company made it happen in just a little over a decade.

Who knows what wonders capitalism and freedom could accomplish, if we simply had the courage to let it?

Advocacy group in India calls for criminal prosecution of Musk and Starlink

10:56 am

A non-profit advocacy group in India, dubbed Telecom Watchdog, has demanded that the Indian government prosecute Elon Musk and Starlink because it asks for and gets $100 deposits from customers without guaranteeing a specific delivery date for its Starlink internet service.

The organisation further asked the telecom regulator to take effective steps to ensure refund with interest, and reprimand the telecom department (DoT) officials of “inaction” on the prevailing issue. [It also] said that the firm was cheating consumers by accepting pre-orders with a deposit of Rs 7,500 ($100) for yet-to-be-launched service.

It is unclear who funds Telecom Watchdog. I would not be surprised if it is backed by those in India who have also have vested interest in SpaceX’s chief competitor, OneWeb. The Indian company, Bharti Enterprises Ltd, has invested $500 million to OneWeb, which plans to initiate service to India next year. Starlink poses a serious financial threat to that roll-out.

Report: Reduce contamination restrictions for some future Mars missions

10:35 am

A new policy paper from the National Academies has proposed reducing the planetary protection rules for some future Mars missions, concluding that Earth life cannot survive on Mars for long, and as long as a lander or rover does not land close to cave entrances or on extensive ice, the need to decontaminate is significantly reduced. From the press release:

In this report, the Committee focused on regions on Mars that might not be negatively impacted if visited by spacecraft that are not stringently sterilized. For missions that do not access the subsurface, such regions could include a significant portion of the surface of Mars, because the UV environment is so biocidal that terrestrial organisms are, in most cases, not likely to survive more than one to two sols, or Martian days. For missions that access the subsurface (down to 1 meter), regions on Mars expected to have patchy or no water ice below the surface might also be visited by spacecraft more relaxed bioburden requirements, because such patchy ice is likely not conducive to the proliferation of terrestrial microorganisms.

The report finds that it is imperative that any mission sent to Mars with reduced bioburden requirements remain some conservative distance from any subsurface access points, such as cave openings. Furthermore, though less stringent than current requirements, these missions with relaxed bioburden requirements would still need some level of cleanliness, which could be achieved for instance using standard aerospace cleanliness practices.

The report essentially concluded that missions to Mars’ dry equatorial regions as well as its glacial mid-latitudes pose no risk to contaminating the red planet with Earth life.

While the press release pushes the idea that this is a reduction in the planetary protection rules, it could be seen in a much worse light. Based on the proposed rules, missions to the Martian poles or higher latitudes, where ice is extensive and not “patchy,” might be entirely forbidden. This will significantly limit Martian exploration by the United States. Meanwhile, China and Russia and others will be faced with no such restrictions.

Note too that this report likely forbids SpaceX from landing its Starship in the company’s candidate landing sites, all of which are in the northern lowland plains ranging from 35 to 40 degrees north latitude. This region is thought to have extensive ice sheets very close to the surface. To land there, the rules proposed will either require extremely strict and very costly decontamination procedures, many of which do not even exist as yet, or will forbid landing there at all.

NASA shifts Starliner crew to Dragon to get them in space

9:54 am

NASA announced yesterday that it is is changing the launch assignments of two astronauts from Boeing’s long delayed Starliner capsule to SpaceX’s Dragon capsule, thus allowing them to get into space sooner.

Astronauts Nicole Mann and Josh Cassada were supposed to be among the first human passengers on Starliner during its first crewed flights in the coming years. Now, they’ll fly together on SpaceX’s fifth crewed mission to the International Space Station, which is slated to take place in the fall of 2022.

Both had been assigned to Starliner in 2018, but the delays at Boeing have left them stranded on the ground while others are flying. Worse, it is now unclear when Starliner will launch, as Boeing has not yet resolved the serious valve issue that scrubbed the launch of Starliner’s second unmanned demo mission in August.

Honda developing reusable rocket

9:45 am

Capitalism in space: As part of a larger plan to diversify its product line, Japanese car manufacturer Honda announced on September 30th that it is developing a reusable rocket comparable to Rocket Lab’s Electron.

Honda’s press release can be found here. In it the company also proposes to develop technologies for use by colonies on the lunar surface.

All of these proposals so far appear to be nothing more than PowerPoint presentations, but according to the first link above, the company says it will spend about $9 billion per year for the next five years on all these projects, which also include developing a robot and an electric plane that takes off and lands vertically. (The dollar amount seems much too high, but it is based on a conversion from the announced $5 trillion yen total Honda says it is going to spend in next five years for this research and development.)

According to the announcement, the rocket won’t launch until 2030, which will get it into the game very late. It better be revolutionary or it won’t garner much business by then.

The wavy and beautiful edge of the northern ice cap of Mars

12:32 pm

The scarp of the north pole icecap on Mars
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on August 7, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the many layered scarp that forms the edge of the northern polar ice cap on Mars, probably more than 2,000 feet high.

Those layers are significant, as they indicate the many climate cycles that scientists think Mars has undergone over the eons as the red planet’s rotational tilt, or obliquity, rocked back and forth from 11 degrees inclination to as much as 60 degrees. At the extremes, the ice cap was either growing or shrinking, while today (at 25 degrees inclination) it appears to be in a steady state.

Why the layers alternate light and dark is not known. The shift from lighter colors at the top half and the dark bottom half marks the separation between the top water ice cap and what scientists label the basal unit. It also marks some major change in Mars’ climate and geology that occurred about 4.5 million years ago.

Military satellite imagery to be obtained from competitive commercial market

9:18 am

Capitalism in space: The National Reconnaissance Office (NRO) is shifting how it gets the government’s military satellite surveillance imagery so that instead of having a long term contract with one company, multiple satellite companies will compete to provide the data.

Under this new imagery procurement, the NRO plans to buy products from multiple vendors and move beyond the current single-supplier arrangement that the National Geospatial Intelligence Agency signed more than a decade ago with DigitalGlobe, which is now Maxar Technologies. The NGA in 2017 turned over responsibilities for commercial imagery procurement to the NRO, while the NGA remains the primary buyer of commercial geospatial data analytics.

The NRO is expected to select at least three U.S. suppliers and structure the program with onramps for new providers. The agency also will require vendors to sign “end user license agreements” so imagery can be shared across government agencies without additional licensing fees.

This change illustrates how other government agencies are following NASA’s lead and shifting from controlling everything to buying the needed product from the open market. While NRO was getting imagery before from a commercial company, Maxar, depending on a single vendor limited competition and innovation while raising costs.

Buying the data from multiple companies means that NRO will get more choice for less cost.

Sunspot update: The boom in sunspots returns!

12:11 pm

It is time for my monthly sunspot update, based on the most recent NOAA monthly graph, showing the changes in the Sun’s sunspot activity during September. That graph is below, annotated to show the previous solar cycle predictions and thus provide context.

In September sunspot activity boomed once again, producing the most sunspots in a month since 2016 and ending the slight drop in activity in August to return to the pattern the Sun has exhibited since the end of solar minimum. Consistently the number of sunspots on the visible hemisphere of the Sun since 2020 has exceeded the April 2020 prediction of the NOAA scientist panel, as indicated by the red curve in the graph.

2018 review by Blue Origin suggested changes that were not adopted

10:52 am

Capitalism in space: Shortly after Bob Smith took over as CEO of Blue Origin he hired a consulting firm to review the company’s corporate culture and management policies, then had a top management briefing to review what that analysis had found.

Notes from that meeting by Blue Origin’s management have now become available, and suggest that the company’s management recognized it needed to make some changes in how it operated in order to better compete with SpaceX. Blue Origin had become hidebound, timid, and structured in a manner that made the creation of cost-effective engineering difficult. For example,

“Traditionally Blue team has not been focused on producibility and cost when designing,” another executive commented.

In response to the Avascent’s report on SpaceX’s cost focus, Blue Origin officials also acknowledged that they did not have an effective means of estimating costs before beginning a project. “Blue is riddled with poor estimating,” one executive wrote, specifically citing the New Glenn rocket. “The estimates barely cover the spot cost buy of that material based on market price, let alone the entire part material purchase. How did SpaceX keep to their target cost? They probably did a good job estimating. How they accomplished such good estimating is beyond me right now, but they did it somehow for their early years.” [emphasis mine]

As noted at the link, however, there is no evidence the company every made any of the suggested changes:

Whatever Bob Smith hoped to glean from the Avascent study, it’s not clear that the work has had a salutary effect on Blue Origin’s culture.

In the nearly three years since the report’s completion, SpaceX has gone on to launch more than 60 rockets, including four human missions, into orbit. SpaceX also has leaped ahead on a number of other fronts, including winning a multi-billion contract from NASA to build a Human Landing System for the Artemis Moon Program.

Blue Origin, by contrast, has succeeded in launching a single human flight on its New Shepard system—carrying Bezos into space for a few minutes in July. The company’s first orbital flight likely remains about three years away. Far from embracing openness, it remains more opaque than ever. And there are emerging questions about the company’s culture.

I would be more blunt. Prior to Bob Smith’s arrival in 2017 Blue Origin’s management style appeared somewhat similar to SpaceX’s, with regular almost monthly test flights of New Shepard. After he arrived everything slowed down, with the management style becoming all the things the 2018 Avascent study found wrong. And in the three years since that report and management meeting, it appears Smith did nothing to change anything. Blue Origin appears to remain a hidebound company going nowhere.

The company has vast resources due to the cash that Jeff Bezos has poured into it. It needs some good courageous leadership however. The main question will be whether Bezos can provide that.

Due to cracks, Russia will no longer use Zvezda’s docking port

9:39 am

Russian officials today revealed that they will no longer use the docking port on its Zvezda module on ISS because of the stress fracture cracks they have found in the section where that port is located.

Russia is unable to use one of the docking ports of the ISS to its full extent due to cracks in the transitional chamber of the Zvezda module, the general designer of Russia’s Energia corporation, associate member of the Russian Academy of Sciences Vladimir Solovyov said on Monday. “The transitional chamber’s loss of airtightness is often mentioned these days. We are very fortunate the cracks are at the end. We shut down that compartment, thus losing one docking port, which narrows our opportunities somewhat. The crack is very insignificant, though,”

In other words, they have sealed the aft section of Zvezda to reduce further air leaks, thus also closing off access to the port.

The Russian portion of ISS presently has two docking ports on two different modules. When Roscosmos launches its Prichal docking hub in November, to be attached to Nauka’s port, they will then add four more ports.

This decision underlines the impending end to ISS’s life span. Zvezda is not the only old Russian module on ISS where stress fractures have been found. “In August they found cracks in the module Zarya, the oldest module on ISS.

Though the U.S. part of ISS shows no such problem, it is designed to rely on the Russian half for its operations. If Russia must shut down its modules then the station will not be able to function for much longer.

The U.S. will likely overcome some of these issues with the planned launch in ’24 of Axiom’s private commercial module to ISS, which will eventually evolve into an complete space station separate from ISS. For the Russians the pressure to design and launch their own new station has become more critical. Whether they can do it however is unknown. Russia has not built a new space station module in decades. Their new ISS module, Nauka, was built in the 1990s.

Space Force payload problems force delay until ’22 of next Falcon Heavy launch

9:18 am

Capitalism in space: The Space Force has announced that because more time is needed to prepare its military payload, the next Falcon Heavy launch, scheduled later this month, will be delayed until ’22.

This is not the first time payload issues have delayed the launch, which had been previously scheduled for July. The Space Force has not announced a new launch date, nor was it very specific in describing the issues that has forced this delay.

As for the Falcon Heavy, though there has been a long delay since its last flight in June 2019, it appears that SpaceX has four launches scheduled for ’22, with another six already contracted and scheduled for later.

UAE to launch probe to asteroid belt

9:01 am

The new colonial movement: The United Arab Emirates (UAE) today announced that it is planning an unmanned probe to visit a number of asteroids in the asteroid belt.

The project targets a 2028 launch with a landing in 2033, a five-year journey in which the spacecraft will travel some 3.6 billion kilometers (2.2 billion miles). The spacecraft would need to slingshot first around Venus and then the Earth to gather enough speed to reach an asteroid some 560 million kilometers (350 million miles) away.

It appears they have not yet chosen their targets in the belt.

The big question will be how much of this project will be built in the UAE, and how much they will have to farm out to others. For their Al-Amal Mars orbiter, the satellite was mostly built by U.S. universities, as they trained UAE engineers, who now run the mission entire.

Russia launches movie director and actor to ISS

8:40 am

Capitalism in space: Early today Russia successfully used its Soyuz-2 rocket and Soyuz capsule to launch a movie crew to ISS to begin a twelve day visit where they will film scenes for a science fiction movie.

An actress Yulia Peresild and a movie director Klim Shipenko arrived at the International Space Station aboard the Soyuz MS-19 spacecraft on Oct. 5, 2021, for a 12-day visit to shoot scenes of a sci-fi drama. They were accompanied by a professional cosmonaut Anton Shkaplerov, who had to switch to manual control during the final approach to the station due to a failure of the Kurs automated rendezvous system aboard Soyuz. Shkaplerov will remain aboard the station for nearly six months.

This is the second in a steady string of passenger commercial spaceflights that have been purchased by various people from either Roscosmos in Russia or SpaceX in the U.S. We shall see two more such flights in December, and another early in ’22, with additional flights to be scheduled beyond that. The full list, at this time:

  • September 15, 2021: SpaceX’s Dragon capsule flew four private citizens on a three day orbital flight
  • October 2021: The Russians launch two passengers to ISS for 12 days to shoot a movie
  • December 2021: The Russians will fly billionaire Yusaku Maezawa and his assistant to ISS for 12 days
  • cDecember 2021: Space Adventures, using a Dragon capsule, will fly four in orbit for five days
  • January/February 2022: Axiom, using a Dragon capsule, will fly four tourists to ISS
  • 2022-2024: Three more Axiom tourist flights on Dragon to ISS
  • 2024: Axiom begins launching its own modules to ISS, starting construction of its own private space station
  • c2024: SpaceX’s Starship takes Yusaku Maezawa and several others on a journey around the Moon.

Expect this list to grow. There appears to be plenty of demand for such commercial manned spaceflights, and with more flights and more competition (once Boeing’s Starliner enters the game) the cost will certainly drop.

The leaders in the 2021 launch race:

34 China
23 SpaceX
16 Russia
4 Northrop Grumman

With this launch Russia has now exceeded the number of launches it completed last year. If they complete all their presently scheduled launches for ’21, Roscosmos will have its best year since 2015.

The U.S still leads China 35 to 34 in the national rankings.

Worldview to once again develop stratospheric tourist balloon flights

8:55 pm

Capitalism in space: The Tucson-based high altitude balloon company Worldview has now announced that it is going to once again develop tourist balloon flights.

World View, based in Tucson, Ariz., announced Oct. 4 it is developing a passenger capsule that will be carried aloft by balloons to altitudes of about 30 kilometers. The Explorer Space Capsule will host eight passengers and two crew for flights lasting 6 to 12 hours, giving people a view of the Earth the company argues resembles that seen from space.

Tickets will cost $50,000 per person, with World View providing what it calls “flexible financing options.” The company expects the first flight no earlier than early 2024, with the nonprofit organization Space for Humanity, which offers spaceflight experiences for those who cannot afford tickets, buying the inaugural flight….

This project is a return to World View’s origins nearly a decade ago. The company originally said it would develop a stratospheric balloon system called Voyager for carrying people, offering them an aspect of the spaceflight experience without actually going to space. However, several years later the company shifted its attention to uncrewed balloons called “stratollites” that carry imaging and communications payloads into the stratosphere for weeks at a time.

The company’s CEO said they are hoping to pick up business from the suborbital market by offering a near-space experience that lasts hours for about one tenth the cost.

Worldview is now in direct competition with Space Perspectives, based in Florida and intending to fly passengers on high altitude balloon flights by ’24, but for $125k per ticket. That company was founded by the same people that founded Worldview.

It shows a typical example of the many slope streaks found in the rough and very broken region north of the Martian volcano Olympus Mons, the largest in the solar system.

See this May 2019 post for a detailed explanation of slope streaks. While they appear to be avalanches, they do not change the topography of the ground, sometimes flow over rises, and appear to be a phenomenon entirely unique to Mars. While no theory as yet explains them fully, the two most favored postulate that they are either dust avalanches or the percolation of a brine of chloride and/or perchlorate in a thin layer several inches thick close to the surface. In both cases the streak is mostly only a stain on the surface that fades with time.

The location of this cool image however tells us something more about them.

Italy switches from Arianespace to SpaceX for launch contract

9:05 am

Capitalism in space: Because of the two recent launch failures of Arianespace’s Vega rocket (built mostly in Italy), the Italian space agency (ASI) has decided to take the launch of an Earth observation satellite from Arianespace and award the launch contract instead to SpaceX.

The article at the link describes in detail the history and politics that make this decision significant. Essentially, because Arianespace in the past decade has failed to meet the challenge of SpaceX, so that its launches continue to be more expensive, this government-subsidized business has tried to force nations in the European Space Agency (ESA) to use Arianespace rockets via political agreements.

With this decision Italy is defying that pressure, which in turn is going to increase the pressure on Arianespace to finally step up its game, or die from lack of business. For example, when the ESA agreed to have Arianespace build its next generation rocket, the Ariane 6, it failed to require it to be reuseable. The Ariane 6 rocket was therefore designed as an expendable rocket, which meant that right from the start it could not compete with SpaceX’s Falcon 9. It has therefore failed to win launch contracts.

Expect the Ariane 6 to continue to fade as the years pass, simply because the bureaucrats in ESA and Arianespace refused to take their competition seriously.

William Shatner to fly on next New Shepard suborbital flight

8:47 am

Capitalism in space: Blue Origin today announced that William Shatner will join three other passengers on its next New Shepard suborbital flight, presently scheduled for October 12th.

Today, Blue Origin announced actor William Shatner and Audrey Powers, Blue Origin’s Vice President of Mission & Flight Operations, will fly on board New Shepard NS-18. They will join crewmates Chris Boshuizen and Glen de Vries for the flight which lifts off from Launch Site One on October 12.

Powers appears to be flying as both a reward for her work at Blue Origin and as a engineer to observe the operation of the spacecraft.

Shatner, an actor for more than six decades and most famous for his role as James T. Kirk in Star Trek, is 90 years old, which will make him the oldest person to ever fly into space.

BeppiColombo’s first images of Mercury

10:52 pm

Mercury by BebiColomo
Click for full image.

This past weekend the European/Japanese duel-orbiter mission made its first flyby of Mercury, taking its first images of that planet.

The photo to the right is one example, cropped and reduced slightly to post here. It was taken by the spacecraft’s monitoring cameras, designed for engineering purposes, which means the resolution is not very high and the camera is positioned so that parts of the spacecraft were visible in each shot. For example, the white strut in the lower right is the spacecraft’s magnetometer boom, which also was used to gather data during the flyby.

Still, the photos demonstrated that the spacecraft is pointing correctly and on course. It will complete five more Mercury fly-bys before going into orbit in 2025.

The next flyby will occur in June ’22.

NASA issues request for commercially-built spacesuits for its Artemis program

10:39 pm

Capitalism in space: After more than a decade of delays in building its own in-house next generation spacesuits, NASA this week issued a request for proposals from the commercial space industry for new spacesuits for its Artemis program.

Bidders can use the technology NASA developed for [its unfinished upgraded spacesuits] in its proposals, or they can use their own designs, the document states. The suits must be able to meet a variety of requirements, including up to six spacewalks on the lunar surface during initial Artemis Moon missions. They must also be made of materials such that less than 100 grams of lunar regolith is brought back into the “cabin environment” after each spacewalk on the Moon. NASA plans to award a contract by next April.

The plan is comparable to what NASA has been doing across the board now for the last three years, buy the product from the commercial sector in a fixed price contract. The company that builds the suits will retain ownership of the design, and can make money selling its use to others.

This policy approach continues the agency’s acceptance of almost all the recommendations put forth in my 2017 policy paper, Capitalism in Space, a free pdf download.

It also likely means NASA might finally get the spacesuits it needs for future lunar missions quickly and at a reasonable cost, something the agency itself has been unable to do.
