High altitude tourist balloon company, Space Perspective, raises $40 million

9:12 am

Capitalism in space: The Florida-based high altitude tourist balloon company, Space Perspective, has successfully secured $40 million in investment capital funding, which the company says will be sufficient for them to begin flights by 2024.

Unlike other space-tourism companies, Space Perspective isn’t relying on rockets to send passengers to space. Instead, it will use a balloon to carry its roomy pressurized “Spaceship Neptune” capsule up to 100,000 feet before gently coming back down to Earth and splashing down in the Gulf of Mexico.

Each trip is expected to last about six hours with about two hours at the 100,000-foot mark.

They say their ticket price will be $125,000, which is far less than the suborbital space missions of Blue Origin or Virgin Galactic, but significantly more than the $50,000 that the other U.S. high altitude balloon company, Arizona-based Worldview, says it will charge for similar flights.

Nonetheless, the company’s CEO says they have already booked 25 flights.

Watch launch of next crew to Chinese space station

9:00 am

I have embedded the live stream of today’s launch of three astronauts to China’s space station, presently being assembled in orbit. This crew’s mission is planned for six months. More details here. From China’s state-run press is this description of the planned tasks during the mission, including two or three spacewalks as well as the addition of two more large modules to the station.

Liftoff is set for 12:23:44 p.m. (Eastern).

Virgin Galactic delays next Unity suborbital flight until next year

12:18 am

Capitalism in space: Virgin Galactic announced today that it is delaying its next Unity suborbital manned flight until next year so that it can first complete a planned maintenance inspection and overhaul of both Unity and its carrier airplane WhiteKnightTwo.

The company said Oct. 14 that it decided to move directly intended a planned maintenance period after a recent lab test of materials used on the vehicles “flagged a possible reduction in the strength margins of certain materials used to modify specific joints” that “requires further physical inspection.”

…That decision means that the company will delay Unity 23, a mission for the Italian Air Force that had been scheduled for as soon as mid-October, until after the maintenance period is completed next year. That flight had been previously scheduled for late September or early October but postponed to look into a potential manufacturing defect with a component in a flight control actuation system.

The endless delays at Virgin Galactic, stretching out now for almost fifteen years, threaten this company’s competitive standing. With Blue Origin now apparently able to fly commercially and regularly, one wonders why anyone would risk flying on Unity. Of course, people will, once the ship is cleared for commercial flights, but right now the price will likely have to be less than what Blue Origin is charging to garner business.

China launches eleven satellites on Long March 2D rocket

12:08 am

China today launched eleven satellites using its Long March 2D rocket, with the primary payload a solar observation telescope, designed to observe the Sun in the hydrogen-alpha wavebands.

The hydrogen-alpha wavelength is deep red and is centered at 656.28 nanometers – for comparison, visible light runs from 400 to 700 nanometers. Observing the Sun at the hydrogen-alpha wavelength can reveal structures, evolution, and dynamic processes associated with solar flares and filaments. Hydrogen-alpha observations can also reveal solar wave phenomena, which are precursors to coronal mass ejections, and the dynamics of activity in the Sun’s lower atmosphere.

The rocket’s first stage was also equipped with grid fins similar to those used on SpaceX’s Falcon 9. Their goal at this time is simply to more precisely guide that expendable first stage back to its drop zone in the interior of China, thereby preventing it from crashing into habitable areas.

The leaders in the 2021 launch race:

35 China
23 SpaceX
17 Russia
4 Northrop Grumman

The U.S. and China are now tied at 35 successful launches in the national rankings. With three more launches expected in the next three days, one by China and two by the U.S., expect these numbers to rise quickly.

Hubble data detects persistent water vapor on one of Europa’s hemispheres

1:30 pm

Using data from the Hubble Space Telescope spanning sixteen Earth years, scientists have detected the presence of water vapor on Europa, but strangely spread only across one of the moon’s hemispheres.

Previous observations of water vapor on Europa have been associated with plumes erupting through the ice, as photographed by Hubble in 2013. They are analogous to geysers on Earth, but extend more than 60 miles high. They produce transient blobs of water vapor in the moon’s atmosphere, which is only one-billionth the surface pressure of Earth’s atmosphere.

The new results, however, show similar amounts of water vapor spread over a larger area of Europa in Hubble observations spanning from 1999 to 2015. This suggests a long-term presence of a water vapor atmosphere only in Europa’s trailing hemisphere – that portion of the moon that is always opposite its direction of motion along its orbit. The cause of this asymmetry between the leading and trailing hemisphere is not fully understood.

First, it must be emphasized that the amounts of atmospheric water being discussed are tiny, so tiny that on Earth we might consider this a vacuum.

Second, that the water vapor is only seen on the trailing hemisphere suggests there is some sort of orbital influence involved, though what that influence is remains unknown.

Hopefully when Europa Clipper finally arrives in orbit around Jupiter in 2030, with a path that will fly past Europa fifty times, we will some clarity on these questions.

A gecko on Mars

12:24 pm

Gecko on Mars
Click for full image.

Today’s cool image is also today’s picture of the day from the science team of the high resolution camera on Mars Reconnaissance Orbiter (MRO. That picture, rotated, cropped, and reduced to post here, can be seen to the right. As the caption authors Sharon Wilson and Sarah Sutton write:

The smooth volcanic surfaces in the Gordii Fossae region are sometimes interrupted by long, narrow troughs, or fissures. These fissures form when underground faults, possibly involving magma movement, reach the near-surface, allowing material to collapse into pits or an elongated trough. This fissure appears to have erupted material that flowed onto the surface.

If you use your imagination, this trough resembles a gecko with its long tail and web-shaped feet!

This impression is even more evident in the wider image taken by MRO’s context camera below.

Shatner vs today’s America

9:17 am

Shatner vs everyone else
Shatner, on the left, turns away from Bezos and the spray of champagne.

Capitalism in space: The profound, emotional, and thoughtful reaction of William Shatner to his short suborbital flight yesterday on Blue Origin’s New Shepard space capsule contrasted starkly with the crass, rude, and shallow response of his co-passengers and Jeff Bezos.

You can watch Shatner’s comments right after landing at the video at the link. Watch how he tries to express his thoughts to Bezos immediately, and is almost ignored as Bezos and the others instead want to spritz champagne at each other. Shatner turns away, almost in disgust. The screen capture to the right shows him turning away, not because he doesn’t want to be hit by champagne but because he doesn’t want that shallowness to steal from him the emotions he now feels.

Eventually Bezos realizes Shatner is going to say his peace, and that he better pay attention. Shatner, almost in tears, struggles to note how shocked he was at the relative thinness of the atmosphere. To him, the rocket so quickly zipped out of a blue sky into blackness. As he said,

“This air, which is keeping us alive, is thinner than your skin. It’s a sliver. It’s immeasurably small when you think in terms of the universe.

…”What you have given me is the most profound experience I can imagine. I’m so filled with emotion about what just happened … it’s extraordinary. I hope I never recover, that I can maintain what I feel now. I don’t want to lose it. It’s so much larger than me and life.”

Shatner is an actor. For him, the emotion is the most important thing, as that is what he has specialized in expressing on screen to others for his entire life. At this moment, however, he was not expressing the emotions of a imaginary character he was creating on screen, but his own personal emotions. He managed to do it, in the best way possible. God speed William Shatner. We shall miss you when you are gone.

That Bezos was so unprepared for this moment from Shatner was very unfortunate. It made him look very shallow and foolish, which is a shame because, as Shatner so correctly noted, Bezos was the one who made that moment possible.

Shatner, at ninety years of age, is of a different more civilized generation that believed strongly in applying thought to one’s emotions, rather than letting those emotions rule. The contrast between him and all the younger people in this clip gives us a clear snapshot of an America now gone, replaced by the thoughtless emotional America of today.

Russia launches another 36 OneWeb satellites

8:37 am

A Russian Soyuz-2 rocket today successfully launched 36 more OneWeb satellites, raising the total of the satellite constellation in orbit to 358.

The launch was from Russia’s new spaceport Vostochny. As with all launches from Russia, the expendable first stage core and strap-ons landed inside Russia within designated drop zones. And as usual, no word from Russia on whether they landed on anyone’s head.

The leaders in the 2021 launch race:

34 China
23 SpaceX
17 Russia
4 Northrop Grumman

The U.S. still leads China in the national rankings, 35 to 34. With launches scheduled by both countries (two by the U.S. and one by China) over the next three days, these numbers will continue upward.

Webb telescope finally arrives at launch site in French Guiana

2:54 pm

Webb deployment

After almost twenty years of construction (a decade behind schedule) and a cost of $10 billion, ($9.5 billion over budget), the James Webb Space Telescope today arrived at the processing facility at Arianespace’s French Guiana spaceport, where it will be prepared for a December 18, 2021 launch on an Ariane 5 rocket.

Once launched the telescope, which is not a replacement for Hubble because it observes in the infrared (not optical) and is optimized for deep space cosmology, will take two weeks to reach its orbital position about a million miles from Earth, as shown in the graphic.

Let us all cross our fingers and toes that it all works as designed, for if it doesn’t this will be the biggest failure ever in the history of NASA.

Astronaut blood samples suggest long-term exposure to weightlessness causes brain damage

2:10 pm

New research comparing blood samples taken from five Russian astronauts before and after long term missions to ISS suggests that weightlessness can cause brain damage.

Published in JAMA Neurology, the new research looked at five male Russian cosmonauts. Each spent an average of 169 days in space. Blood samples were taken from each subject before leaving Earth, and then at three points after returning.

Five different blood-based biomarkers were measured, each known to correlate with some kind of brain damage. Three biomarkers in particular were found to be significantly elevated after the cosmonauts returned to Earth – neurofilament light (NfL), glial fibrillary acidic protein (GFAP), and a specific type of amyloid beta protein.

The researchers hypothesize the increases in NfL and GFAP levels may indicate a type of neurodegeneration called axonal disintegration. Elevated NfL levels are currently being investigated as a way of detecting the earliest stages of brain damage associated with Alzheimer’s disease.

It must be emphasized that the research did not find brain damage, only data within the blood samples that is often associated with brain damage. More research is required to determine if these biomarkers indicate the same thing in space as they do on Earth.

Australia to build unmanned lunar rover for NASA

7:06 am

NASA and Australia have signed a deal whereby Australia will provide an unmanned lunar rover on which NASA will put its science instruments, with the package taken to the Moon by a commercial lander.

As part of the agreement, a consortium of Australian businesses and research organizations will develop a small rover that can operate on the lunar surface. The rover would have the ability to pick up and transfer lunar regolith (broken rock and dust) to a NASA-operated in-situ resource utilization (ISRU) system on a commercial lunar lander. Such a rover could fly to the Moon as early as 2026.

While this agreement helps widen the competition in the commercial unmanned planetary aerospace industry, it does so by helping the industry of another country. This policy fits the general philosophy of the Democratic Party and the Biden administration, which generally focuses on aiding other countries before the U.S.

Watching the New Shepard suborbital flight with William Shatner

10:44 pm

I have embedded the live stream of the Blue Origin suborbital flight today of its New Shepard spacecraft, carrying four passengers including William Shatner.

The launch is presently scheduled for 7 am (Pacific). The live stream will start about 5:30 am (Pacific).

As I have noted previously, the announcers for Blue Origin tend to blather quite a bit, hyping the situation to a point of nausea. Hopefully during the flight they will shut up and allow the voices of the passengers to take center stage.

I meanwhile will be on the road during the flight. I will try to post updates as well as my normal news stories, but both might have to wait until I return home in the early afternoon. Regardless, the live stream is below for you to enjoy.

Dusty chaos in Martian canyons

1:37 pm

Outcrops in dusty chaos on Mars
Click for full image.

Cool image time! The photo to the right, cropped and reduced to post here, was taken on May 30, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the dusty dry floor of the chaos region of rough terrain in a side canyon of Valles Marineris, near its outlet. The color strip and the bright outcrops suggest that this terrain contains interesting minerals and resources. To determine exactly what those materials are however requires more information not available in this photo.

This ancient chaos terrain is the leftover eroded sea floor of a intermittent inland sea, leftover water from the catastrophic floods that are theorized to have flowed out of Valles Marineris and carved its gigantic canyons.

The overview map below shows this hypothesized sea.

Shetland spaceport gets 10-year launch contract from new British rocket company

8:50 am

Capitalism in space: The new spaceport in Shetland, Scotland, has signed a 10-year launch contract from the new British rocket company, Skyrora.

Rocket company Skyrora has agreed a multi-launch deal with the SaxaVord spaceport on Unst, the most northerly of the Shetland Islands, as it moves closer to launching its XL rocket in 2022. This is the first agreement Skyrora has made with a Scottish Spaceport. If successful, this could be the first rocket to go to space from the UK.

The deal with SaxaVord [the new name for the Shetland spaceport] will run for the next decade, giving Skyrora the ability to build towards its target of 16 launches a year by 2030.

The XL rocket is designed to launch smallsats, and will compete with companies like Astra and Rocket Lab. If Skyrora is success, it will not only be the first rocket to launch from the UK, it will be the first British-built rocket to launch since October 1971.

Astra schedules next launch attempt

8:36 am

Capitalism in space: The new smallsat rocket company Astra has completed its investigation of its launch failure on August 28th and scheduled its next launch attempt for no earlier than October 27th.

During liftoff, kerosene fuel and liquid oxygen both leaked from the propellant supply system adjacent to the rocket. This system is designed to quickly disconnect and seal when the rocket launches. When LV0006 lifted off, these leaked propellants mixed and became trapped beneath the interface between the rocket and the ground equipment.

These mixed propellants were subsequently ignited by the exhaust of the first stage engines, which caused an over-pressurization that severed the electrical connection which controls the fuel pump. This caused the shutdown of one Delphin on the first stage less than one second after liftoff.

The company has revised its system to prevent further leaks, and shifted the fuel lines so that even if there is a leak, the propellants can no longer mix.

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.

Washington Post slams Blue Origin

9:18 am

Capitalism in space: In a long article today the Washington Post — owned by Jeff Bezos — harshly criticized the management at Bezos’s space company Blue Origin, confirming earlier stories last week (here and here) and published by other news sources that accused the company of poor management and an unhealthy corporate culture. From the Post’s article:

The new management’s “authoritarian bro culture,” as one former employee put it, affected how decisions were made and permeated the institution, translating into condescending, sometimes humiliating, comments and harassment toward some women and a stagnant top-down hierarchy that frustrated many employees.

Though the story strongly confirms those earlier reports, I found it somewhat hilarious in that it seemed far more interested in “woke” issues than Blue Origin’s inability to get anything actually built.

However, that Jeff Bezos allowed the Washington Post to publish it suggests strongly that Bezos is getting ready to take harsh action at Blue Origin, and is laying the groundwork through his newspaper. If so, this is excellent news, as it might mean this very disappointing company might finally get back on track.

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.
