Inspiration4 passengers scheduled for return to Earth tonight

9:01 am

The first entirely private manned orbital mission to space is now scheduled to return to Earth tonight, with splashdown set for 7:06 pm (eastern).

The SpaceX live stream of the landing will begin approximately 4:30 pm (eastern).

Yesterday the passengers released some videos, including a conversation with children who are cancer patients at St. Jude Children’s Research Hospital. They also provided a video update to the general public.

As I noted yesterday, the primary goal of this flight is to raise money for St. Jude. If you wish to send a donation to St. Jude as part of the Inspiration4 spaceflight, you can do so here. You can donate cash directly, or you can bid to win one or more of a variety of items that are on the flight now.

Badlands on the floor of a Martian crater

Badlands on the floor of a Martian crater
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced to post here, shows one small section of a 30-mile-wide unnamed crater in the cratered equatorial regions of Mars northeast of Hellas Basin. Taken on July 21, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), the science team labeled merely as “Rocky crater fill.”

Being at 17 degrees south latitude, there shouldn’t be any ice features in this crater, and the high resolution image to the right seems to confirm this. All we see is an endless plain made up of innumerable small sharp rock ridges interspersed with small low areas filled with sand dunes. This is bed rock, and if its strange stucco-like appearance was caused by a past glacial era, that era is long gone.

Below is a mosaic showing the entire crater, created from two MRO context camera images.

FAA now taking public comments on the licensing of SpaceX to launch Starship/Superheavy from Boca Chica

10:59 am

Capitalism in space: The FAA today announced by email that it is now taking public comments on the “Draft Programmatic Environmental Assessment (PEA)” it requires from SpaceX before it can issue a launch license at Boca Chica, Texas for Starship/Superheavy orbital launches.

From the email:

The FAA invites interested agencies, organizations, Native American tribes, and members of the public to submit comments on all aspects of the Draft PEA. Public comments are due on Monday, October 18, 2021. Comments or questions on the Draft PEA can be addressed to Ms. Stacey Zee, SpaceX PEA, c/o ICF, 9300 Lee Highway, Fairfax, VA 22031. Comments may also be submitted by email to SpaceXBocaChica@icf.com. Before including your address, phone number, e-mail address, or other personal identifying information in your comment, be advised that your entire comment – including your personal identifying information – may be made publicly available at any time. While you can ask us in your comment to withhold from public review your personal identifying information, we cannot guarantee that we will be able to do so.

The FAA will also hold two public hearings on October 6th and 7th, though it provided no information yet on where those hearings will be held.

This announcement means that the Starship/Superheavy orbital test flight cannot occur any earlier than October 18, 2021, and will actually occur at least several weeks or months later, based on the schedule outlined on slide 32 of this FAA presentation [pdf]. Once the 30-day public comment period ends the FAA must then hold “an industry workshop” reviewing the comments and then issue an update of the PEA, or a rejection of it.

Though the chances of the FAA rejecting SpaceX’s permit are practically nil, I fully expect this process to be slow-walked by the FAA under orders of the Biden administration in order to do whatever it can to prevent this orbital flight occurring before SLS’s first launch, now expected in early ’22.

I hope I am wrong, and that the FAA surprises me. We can only wait and see.

Update: If you think I am crazy thinking that the politics of the Biden administration will cause a slowdown in the FAA’s process, just read this story about the FAA suddenly imposing flight restrictions at the southern border to block drone flights by media outlets that show the illegal immigrant crisis there.

“We’ve learned that the FAA just implemented a two week TFR (Temporary Flight Restrictions) over the international bridge in Del Rio, TX, meaning we can no longer fly our FOX drone over it to show images of the thousands of migrants,” Fox News reporter Bill Melugin tweeted. “FAA says ‘special security reason.’”

Fox’s report resulted in a quick lifting of this flight restriction on their drone, but the action by the Biden administration shows that it is quite willing to interfere with normal aviation regulations for its own political reasons.

India signs deal with private rocket startup

9:57 am

Capitalism in space: India’s new Department of Space, dedicated to encouraging the growth of a private commercial and independent Indian space industry, has signed a deal with the private rocket startup, Agnikul Cosmos, to give it access to government space facilities as it develops its own smallsat rocket.

Indian startup Agnikul Cosmos signed a framework memorandum of understanding (MOU) with India’s Department of Space on Friday for access to ISRO facilities and expertise for the development of its two-stage small-satellite Agnibaan launch vehicle.

“The Framework MoU…will enable the company for undertaking multiple tests and access facilities at various ISRO centers for testing and qualification of their single piece 3D printed Semi Cryo engine and other systems. The MoU also enable Agnikul to avail technical expertise of ISRO for testing and qualifying their space launch vehicle systems and subsystems,” ISRO said in a press release.

The company has raised more than $14.1 million in investment capital, and hopes to complete the first launch of its Agnibaan rocket by ’22.

Inspiration4 has raised $130 million so far for St. Jude out of $200 million goal

9:50 am

Capitalism in space: Inspiration4, the first privately launched manned orbital mission has so far raised about $130 million for St. Jude Children’s Research Hospital, still short of the $200 million goal that Jared Isaacman had set when he bought the flight from SpaceX.

A portion of the money came from 72,000 entrants in a sweepstakes that offered the chance to win a seat on the flight. Entrants were encouraged, but not required, to donate to St. Jude, according to the contest rules, which estimated the retail value of the space flight at $2.21 million.

Crew member Chris Sembroski, a 42-year-old data engineer and U.S. Air Force veteran from Everett, Wash., entered the lottery by donating. He didn’t win, but a friend did and gave him the slot, according to the Associated Press.

If you wish to send a donation to St. Jude as part of the Inspiration4 spaceflight, you can do so here. You can donate cash directly, or you can bid to win one or more of a variety of items that are on the flight now.

China’s three astronauts land safely

9:33 am

The new colonial movement: China’s three astronauts safely returned to Earth today after spending 91 days in space and 90 days on China’s new space station.

During their stay they did two spacewalks preparing the station for additional modules and later missions.

China is expected to send the robotic Tianzhou 3 cargo spacecraft toward Tianhe around Sept. 20. And the next crewed mission to the module, the six-month-long Shenzhou 13, is apparently scheduled to launch in mid-October. (Exact target dates are hard to come by with Chinese missions, because the nation tends not to announce many details of its spaceflight plans in advance.)

China will also in the next year launch two more large modules to attach to the station, using its Long March 5B rocket. Assuming they have not redesigned that rocket, expect the very large upper stage on both launches to once again crash out-of-control somewhere on the Earth, possibly in habitable areas.

Curiosity: Into the mountains!

Overview map
Click for interactive map.

Time for another cool image from Curiosity. The photo above was taken by one of the rover’s navigation cameras today, and looks south in the direction of Curiosity’s future travels. The red dotted line shows that planned route, along the cliff face to then turn west into what the science team has dubbed Maria Gordon Notch, in honor of a Scottish scientist from the early 20th century.

The map to the right gives the context as seen from above, as well as the planned travels beyond the notch. The white dotted route marks Curiosity’s actual travel route. The red dotted line marks the planned route. The yellow lines the area seen in the above picture.

At present Curiosity is paused as it performs a new drilling campaign about 200 feet from the base of that cliff face, drilling the rover’s 33rd hole on Mars.

The outcrop resembling a ship’s prow on the image’s right, which I still consider the most spectacular rock outcrop seen yet on any planetary mission anywhere, is about 100 feet high.

Chinese astronauts undock from space station in return to Earth

10:07 am

The new colonial movement: Three Chinese astronauts, having completed their 90 day mission on China’s new space station, early today boarded their Shenzhou capsule and undocked from the station, with the expectation that they will return to Earth sometime tomorrow.

The astronauts have already set China’s record for the most time spent in space. After launching on June 17, mission commander Nie and astronauts Liu and Tang went on two spacewalks, deployed a 10-meter (33-foot) mechanical arm, and had a video call with Communist Party leader Xi Jinping.

Following their safe return, China will launch another unmanned cargo freighter to the station, followed by the launch of three more astronauts for another 90 day mission, continuing the station’s assembly construction. In addition to several more manned flights, in the next two years two more large modules will added.

NOTE: The New York Times actually did some good [and increasingly rare] journalism today to point out that the number of people presently in space, 14, is a record, beating the 13 that were on ISS in 2009. The difference now is that those spacefarers are on three different and very independent projects, ISS, the Chinese space program, and the first entirely private space mission launched by SpaceX.

NASA awards small design lunar lander contracts to five companies

9:58 am

In what appears to be an effort by NASA to placate the losers in the bidding for the manned lunar lander contract, won by SpaceX’s Starship, the agency this week awarded small design contracts related to future lunar lander construction to five different companies, totaling $ 146 million and with the large bulk of the cash going to those losers.

The contracts were as follows:

  • Dynetics (a Leidos company) of Huntsville, Alabama, $40.8 million.
  • Lockheed Martin of Littleton, Colorado, $35.2 million.
  • Northrop Grumman of Dulles, Virginia, $34.8 million.
  • Blue Origin Federation of Kent, Washington, $25.6 million.
  • SpaceX of Hawthorne, California, $9.4 million.

From the press release:

The selected companies will develop lander design concepts, evaluating their performance, design, construction standards, mission assurance requirements, interfaces, safety, crew health accommodations, and medical capabilities. The companies will also mitigate lunar lander risks by conducting critical component tests and advancing the maturity of key technologies.

While the distribution of the money suggests NASA wishes to provide the most support to the companies that lost the bid, it also gives us a hint of what the agency presently thinks of those losers. Of the losers, Blue Origin received the least, suggesting that NASA remains skeptical of that company’s effort. It also might be NASA’s signal to Blue Origin that endless lawsuits and protests — rather than actual construction — is not a good way to make friends and influence people. This conclusion is reinforced by the fact that Dynetics received the most cash, even though like Blue Origin it has yet to launch anything into orbit.

This distribution of money is also part of the typical pattern of DC crony capitalism, designed almost like pay offs to capture these companies and make them partners in the Washington swamp.

One big space company, Boeing, however received nothing. The company might not have submitted a proposal, but I suspect that if it did, NASA dismissed it outright based on the agency’s decision last year to eliminate Boeing from such contract considerations because of the incredible weakness of its recent bids. I think that Boeing will remain on the outs until it finally gets Starliner flying and operational.

SpaceX leases several large facilities in Brownsville, Texas

9:36 am

Capitalism in space: In a clear sign that SpaceX plans to expand its Starship/Superheavy operations in Boca Chica, Texas, it has now leased several large facilities in nearby Brownsville.

Earlier this month, the company signed leases with the Brownsville South Padre Island Airport (BRO) for 46,000 square feet of warehouse space and a neighboring private industrial park owned by PacVentures for 60,000 square feet of warehouse space. Francisco Partida, the airport’s special projects manager, said talks with SpaceX about leasing the former Taylorcraft building at 2100 Les Mauldin Road began in mid-July.

The company was looking for 100,000 square feet of warehouse, which the airport couldn’t supply, though SpaceX found the additional square footage it needed in the privately owned industrial park at 1900 Billy Mitchell Blvd., he said.

SpaceX has also committed about a half million dollars to repairing and refurbishing the airport warehouse.

Astronaut’s mission on ISS will be extended to almost a year

9:30 am

As expected because the Russian’s have taken his return seat in October to bring home two commercial passengers (a film director and his star actress), the mission of astronaut Mark Vande Hei has been extended to March for a total of 353 days in space, just short of a year.

This time will exceed the previous American record for the longest spaceflight, set by Scott Kelly during his 340 day mission in 2015. It remains below about four Russian flights that lasted a full year or more, including the longest flight so far by Valeri Polyakov of 438 days in 1993 and 1994.

Meanwhile, there is no word on the state of the pinched nerve that forced NASA to replace Vande Hei on an upcoming spacewalk. It is likely that weightlessness is probably helping it heal, but NASA and Vande Hei are presently keeping this personal medical information private.

The real human exploration of the solar system began on September 15, 2021

11:26 pm

Falcon 9 at T+13 seconds

Capitalism in space: First the news: On September 15, 2021 SpaceX successfully placed four civilians into orbit using its Falcon 9 rocket and Dragon capsule.

Thus began the first private manned orbital mission in space, planned to last three days and reach an altitude of 595 kilometers or 370 miles, the highest any person has flown in space in decades.

The first stage, on its third flight, successfully landed for reuse. The Dragon capsule, Resilience, was on its second manned flight. The leaders in the 2021 launch race:

31 China
23 SpaceX
15 Russia
4 Northrop Grumman

The U.S. now leads China 34 to 31 in the national rankings.

Now the significance: There was one moment about five minutes after lift off that revealed the fundamental difference between this real flight into space and the short suborbital hops that Blue Origin and Virgin Galactic did in July.

The three most critical moments of any launch had just been completed. The first stage engines had cut off, the first stage had separated successfully, and the single upper stage engine had ignited. It was now lifting the capsule towards orbit, with the only major technical task left were its engine cut off and the separation of the Dragon capsule.

At that moment John Insprucker, principal integretion engineer for SpaceX and frequent host during its launch live streams, made a quick comment that was clearly meant to illustrate the vast difference in achievement between this flight and those two July suborbital flights. He said,

Lozenge-shaped hole in Martian crater

12:15 pm

Hole in crater floor
Click for full image.

Cool image time! The photo to the right, rotated, cropped, reduced, and enhanced to post here, was taken on June 7, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The left image shows what the scientists have dubbed a “lozenge-shaped depression” in the middle of an unnamed 60-mile-wide crater in the southern cratered highlands of Mars. The right image shows the same exact depression, but I have brightened the photo in order to see the details in the shadowed depression.

Though the image is inconclusive, the bottom of the darkest spot in that depression cannot be seen, suggesting it could be an entrance into a larger void below.

Even if there is no voids below, why is this depression here? What caused it? The wider view of MRO’s context camera below might give us a hint.

Watching the first all-private commercial manned orbital spaceflight

11:20 pm

Liberty and freedom enlightening the world
Liberty and freedom enlightening not only the world,
but the entire solar system.

Bumped: I will be out on a cave trip for most of today, September 15, 2021, so I’ve moved this post to the top of the page, as it clearly will be the most important space news today. I should be back before launch, but if not, enjoy!

Original post:
————————
Capitalism in space: Let’s begin by underlining one fundamental fact about the Inspiration4 manned Dragon orbital space mission, targeted for a September 15th launch tomorrow evening, that makes it different from every other orbital space mission ever flown since Yuri Gagarin completed the first manned mission in 1961:

The government has nothing to do with it.

The launch facilities, the rocket, the capsule, the drone ship where the rocket’s first stage will land, and the entire recovery operation in the ocean are all controlled and owned by SpaceX. The passengers are private citizens, one of whom purchased the flight directly from SpaceX.

It is was organized by 38-year-old billionaire and entrepreneur Jared Isaacman, who is also a highly-capable jet warbird aircraft pilot. When he found out from SpaceX he could be the first to fly an all-commercial mission in Crew Dragon, he fronted $100 million to $200 million required and partnered with St Jude Children’s Research Hospital in a campaign to give away two of the missions seats and raise $200 Million for children’s cancer research.

Every person you will see in mission control, at the launchpad, and on the recovery ships are also private citizens, working for a private company that just happens to be in the business of flying rockets, spaceships, and humans into space. None are government employees, and I would suspect that most don’t want to be.

Not only is this mission privately run, its goals are completely different. While all past space launches were flown for purposes decided by the government, this mission’s goals have been determined by the free participants themselves. SpaceX is making money on the flight, Isaacman and his passengers are getting the chance to fulfill their long-held personal dream of going into space, and Isaacman is also using this flight to raise money for cancer research, a personal passion of his.

The flight itself will be unusual. It will be the first manned mission in more than a decade, since the last shuttle repair mission to the Hubble Space Telescope, to not go to an orbiting space station. Instead, the capsule will spend three days free-flying in orbit around the Earth. To enhance the flight for the passengers, SpaceX removed the docking port on Resilience (the capsule) and replaced it with a viewing port with large windows.

The orbit itself will in a sense push the envelope, as SpaceX plans to loft the capsule to an altitude of about 370 miles, considerably higher than ISS’s orbit of about 260 miles and about 35 miles higher than the mission to Hubble. In fact, the Inspiration4 crew will be the farthest from the Earth’s surface than any human in decades, possibly going back as far as the Apollo era.

For watching this flight I have embedded SpaceX’s live stream below, which you can also find here. You will also be able to find that stream at SpaceX’s YouTube page, where the company is also airing preflight videos.

This mission illustrates the fundamentals that built the United States of America. Give humans freedom, don’t try to tell them what to do, and they will do astonishing and magnificent things, on their own.

Russia launches another set of OneWeb satellites

2:03 pm

Using its Soyuz-2 rocket Russia today successfully launched another 34 OneWeb satellites, launching from Baikonur, Kazakhstan.

At the time of publication about half the satellites have successfully deployed. The rest should be released within the next hour or so.

The leaders in the 2021 launch race:

31 China
22 SpaceX
15 Russia
4 Northrop Grumman

With this launch Russia has now matched its total launches from last year, with three months still to go and a number of launches in ’21 on its manifest. For Russia’s launch industry, 2021 looks like it will be a good year.

The U.S. continues to lead China 33 to 31 in the national rankings.

The layered history of Mars as revealed in Valles Marineris

1:01 pm

Layered cliff in Valles Marineris
Click for full image.

Cool image time! The photo to the right, rotated, cropped, and reduced, shows just one tiny cliff face in the gigantic canyon on Mars dubbed Valles Marineris. The photo was taken on June 13, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

Like many other similar cliff faces that MRO has photographed and that I have previously highlighted, there are many many layers visible here. In fact, it appears that almost every cliff in this part of Valles Marineris is many layered, suggesting that like the Grand Canyon on Earth, the canyon as it was carved exposed in great detail the long geological history of Mars.

In this part of Mars, each layer probably represents the placementof a new layer of volcanic material, pouring out from the giant volcanoes in the Tharsis Bulge to the west. In addition, overlain on this volcanic record are probably deposits lain down by the atmosphere as Mars underwent its many climate cycles due to the regular shifts in its orbit and rotational tilt.

Make concrete on Mars using human blood?

9:17 am

What could possibly go wrong? Scientists at the University of Manchester in the United Kingdom have developed a new formulation that can use material known to exist on Mars, combined with the addition of astronaut blood, to produce useful concrete.

Working with simulated lunar and Martian soils, the team experimented with using human blood and waste products as binding material, and turned up some interesting results.

The work showed that a common protein in the blood called serum albumin could be used as a binder to produce a concrete-like material with compressive strength comparable to ordinary concrete. In investigating the mechanisms at play, the team found the blood proteins “curdle” to form “beta sheets” that extend outward to hold the material together.

Even more interestingly, the team found that urea, a waste product found in urine, sweat and tears, could be incorporated to increase this compressive strength by more than 300 percent. That is to say, the key to cosmic concrete stronger than what we have here on Earth might be found in our blood, sweat and tears (and urine).

This work was inspired by ancient building techniques, which often used pig blood in concrete for similar reasons.

Though a lot of this makes sense, especially the utilization of waste products like urine, the idea that future colonies will tap the blood of their citizens for construction purposes raises so many moral questions I can’t list them all here.

For example, let me throw out one possibility should no one think about this too much on Mars. Why not use this need for blood as a method of criminal punishment? Do something the ruling powers think is wrong and we will suck your blood from you to build the colony!

The moral consequences of our actions require long careful thought. Unfortunately, long careful thought simply no longer exists among today’s intellectual and political classes. Instead, they make almost all their decisions off the cuff, based on what “feels” right to them. You merely have to watch the many interviews of Dr. Anthony Fauci in the past year to see what I mean. Nothing he says about masks or mandates is really based on new research or data. He merely throws out an opinion that feels right, at the moment. Thus, he contradicts himself repeatedly, and most of his advice has been worse than useless, resulting in so many unexpected negative consequences they almost cannot be counted.

Try to imagine the horrors that could take place in a colony on Mars, where resources are in short supply, should construction require the use of human blood and the leadership there approaches its problems with the same cavalier attitude toward moral consequences? I can, and it chills my own blood to the core (no pun intended).

Utilizing a commercial lunar probe to reach geosynchronous orbit around the Earth

8:56 am

Capitalism in space: The commercial startup SpaceFlight Inc has purchased payload space on Intuitive Machines’ second lunar landing mission to the Moon late in ’22 in order to test its Sherpa Escape space tug’s ability to use that flight path to place a satellite into geosynchronous orbit around the Earth.

The tug will also carry the payload of another company, GeoJump, which will test in-space fueling technology developed by another company, Orbit Fab.

Sounds complicated, eh? It isn’t when you think about it. When NASA gave up ownership and design of its lunar landers and instead began buying such products from the private sector, it freed up that private sector to sell its spare payload capacity to anyone who wanted it. On this particular flight Intuitive Machines sold that spare capacity to SpaceFlight, which in turn provided GeoJump and Orbit Fab the space tug for getting their experimental payloads to geosynchronous orbit.

This is a win-win for everyone. Not only are two companies (Intuitive Machines and Spaceflight) making money by selling their capabilities to others, two other companies (GeoJump and Orbit Fab) are now able to test their own space innovations at a much lower cost, and much more quickly than had they depended on a government launch from NASA.

SpaceX successfully launches another 51 Starlink satellites

9:15 pm

Capitalism in space: SpaceX tonight successfully used its Falcon 9 rocket to launch another 51 Starlink satellites into orbit.

At publication, the deployment of the satellites is still about 25 minutes away. [Update: deployment successful.] SpaceX now has about 1,500 working Starlink satellites in orbit.

The Falcon 9’s first stage successfully landed on its drone ship, the tenth flight of this stage, tying the record for the most reuses. Both fairings were also reused. This was also the first Starlink launch from Vandenberg Space Force Base. SpaceX intends to do monthly Starlink launches from Vandenberg for the rest of the year.

The leaders in the 2021 launch race:

31 China
22 SpaceX
14 Russia
4 Northrop Grumman

The U.S. now leads China 33 to 31 in the national rankings.

SpaceX will also launch in two days the first ever entirely private orbital mission to space, whereby it has been hired to carry four private astronauts for three days on the highest orbit since the 2009 last shuttle mission to repair the Hubble Space Telescope.

That flight will inaugurate a schedule of almost monthly private manned commercial missions to orbit, extending into next year and possibly forever. The present schedule:

  • September 15, 2021: SpaceX’s Dragon capsule flies four private citizens on a three day orbital flight
  • October 2021: The Russians will fly two passengers to ISS for 10 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 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.

An example why scientists think there were catastrophic floods on Mars

1:30 pm

Broken mesas on Mars
Click for full image.

Today’s cool image provides a nice illustration why scientists have long assumed that in the distance past there had been catastrophic floods of liquid water on Mars. The photo to the right, rotated, cropped, and reduced to post here, was taken on July 6, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows an east-west gully cutting between mesas to the north and south.

Because the highest mesas seem to be aligned, this suggests they were once part of the same formation, and something came along to carve that gap and gully between them.

What made the break? The overview map below as usual provides some context, which also provides a possible explanation.

DC swamp moving to cancel Trump effort to cut red tape at FAA?

9:12 am

The inspector general of the Department of Transportation has instigated an investigation into the FAA’s recent effort, inaugurated during the Trump administration, to reduce the air space shuttered during launch operations in order to allow more launches with less interference with commercial air traffic.

“Over the past 5 years, FAA has gone from licensing about one commercial space launch per month to now licensing more than one launch every week,” Matthew Hampton, the assistant inspector general for aviation audits, said Wednesday in a memo announcing the probe.

The audit was requested by the ranking members of the House Committee on Transportation and Infrastructure and its Subcommittee on Aviation, Hampton said in the memo. [emphasis mine]

The highlighted words are important. The “ranking members” in the House are Republicans. It appears members of the party supposedly in favor of free enterprise have decided to panic after the relatively minor flight deviation due to high winds that occurred during the Virgin Galactic suborbital flight in July, and are now working to shut down the FAA’s effort to launch more rockets while keeping commercial aviation functioning.

The recent decision to begin shrinking the restricted air space around launches results from the increasing sophistication of rockets. Though new rockets — such as the recent launch failures of Astra’s Rocket-3 and Firefly’s Alpha — do fail and require self-destruction during launch, the launch and flight termination technology today works quite well in better controlling the rocket. When something went wrong during both of these recent launches, the rockets compensated so that they were able to continue to fly to a much higher altitude, where the range officer could more safely destroy them. In the past, failing rockets such as these would have gone out of control, threatening a larger area both in the air and on the ground.

Thus, there now is less need to restrict as much space, unless you have the fantasy that you must rig things so that nothing can ever go wrong.

This fantasy has fueled the entire Wuhan flu panic. It rules the minds of many Washington bureaucrats and politicians, from both parties, who repeatedly declare that “If we can save one life, we must!” Meanwhile this vain effort fails in its main task, since things still go wrong, and the overwrought effort to overly protect people ends up doing more harm than good by squelching all achievement.

It now appears there are Republicans on both the House Committee on Transportation and Infrastructure and its Subcommittee on Aviation who believe in this fantasy. No wonder the Democrats always win in legislative battles. They have many hidden Republican allies.

Another technical problem identified in Virgin Galactic spaceship

8:37 am

Capitalism in space: Virgin Galactic announced late Friday, when few would notice it, that a new technical problem has been identified with its Virgin Galactic spaceship.

In a statement issued late Sept. 10, Virgin Galactic said a third-party supplier, which it did not identify, notified the company of a potential manufacturing defect in a flight control actuation system component. Virgin said it is conducting inspections with the vendor to determine if the suspect component needs to be repaired or replaced.

Because of the inspections, Virgin Galactic said the earliest it would perform the next SpaceShipTwo mission, called Unity 23, is the middle of October. The company had previously stated the mission would take place in late September or early October.

This issue is completely independent from the flight path anomaly that occurred during the July suborbital flight that has caused the FAA to ground Virgin Galactic.

Data from Opportunity suggests surface dew periodically appears even in the dry equatorial regions

4:43 pm

Using data from the rover Opportunity, scientists now think that the renewal of Martian salt crusts on rock surfaces on the rim of Endeavour Crater could possibly by caused by the appearance of rare thin wetting events, and that such events could have even occurred very recently and be on-going..

The scientists looked at the rate of erosion and renewal of the salt crusts, and found them to be in a steady state. The erosion is slow, taking from 200,000 to 2,000,000 years to remove 1 to 2 millimeters. However, periodically a thin film of water or wetting occurs, not unlike dew on Earth, which quickly acts to renew the crust. As David Mittlefehldt of the Astromaterials Research Office at the Johnson Space Center and the lead author of the paper explained to me,

Taken together, the data leaves open the possibility the salt mobilization has occurred within the last few thousand years. It could be ongoing in the sense that over a period of thousands? or hundreds? of years it might happen again.

In other words, the evidence suggests that every few hundred or thousand years the surface of these rocks gets wet, which results in the placement of a new thin layer of salt crusts.

Mittlefehldt also emphasized to me that these wetting events are rare, and “there is also the case that such an event may never come again because of changing conditions.”

The situation is essentially like on Earth, where in some places hydrologists measure the size of floods by how rare they are. A 1,000 year flood is big, but it happens very rarely. At Endeavour Crater these wetting events are comparably rare, but they do not involve big floods, but a mere moistening of the ground.

The location of Endeavour Crater is about 2 degrees south latitude, so it sits in the dry equatorial regions where no surface or near surface ice has so far been found. However, the cyclic nature of Mars’ orbit and obliquity could have changed this in the past, and could change this again in the future. At this time we simply don’t have enough information to know.

On the edge of Mars’ glacier country

1:25 pm

Color dry mesas on Mars
Click for full image.

Today’s cool image sits right on the southern edge of Mars’ northern glacier country, at 29 degrees north latitude. The picture to the right, cropped and reduced to post here, was taken of this location on June 4, 2021 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what appears to be the exposed and scraped bedrock and mesas on the floor of an unnamed 60-mile-wide crater.

That scraped bedrock is quite beautiful, reminiscent of the bare carved mesas and bedrock one sees throughout the southwest of the United States. To hike from that central valley to the top of the bright mesa would be a fine experience, especially because of the suggested change in colors in the color strip.

The overview map below gives more context.

Sunspot update: Activity declines in August to just above prediction

12:02 pm

On September 1st NOAA released its update of its monthly sunspot cycle graph, showing the Sun’s sunspot activity for the past month. That graph is below, annotated to show the previous solar cycle predictions and thus provide context.

In August sunspot activity dropped from July so that it was only slightly above the prediction of NOAA’s panel of solar scientists, as indicated by the red curve. The blank streak at the very end of July ended on August 2nd (a streak of seven days and the longest in years), but was followed during the month by an additional five blank days.

Questions raised about Branson’s most recent Virgin Galactic stock sale

9:31 am

It appears that both Virgin Galactic and Richard Branson might have violated SEC regulations when they sold more than $800 million in stock this summer without notifying buyers of the FAA investigation into the anomaly on Branson’s July 11th suborbital flight that has now grounded all SpaceShipTwo flights.

On July 12, Virgin Galactic announced in a Securities and Exchange Commission filing that it was selling $500 million worth of common stock. The filing did not mention that during its edge-of-space flight the day before, its aircraft deviated from its air-traffic-control clearance, a mishap that would ultimately trigger a Federal Aviation Administration investigation and lead to the indefinite grounding of its space-tourism operation.

The FAA began investigating on July 23, a spokesperson told Insider. On August 11, the agency grounded Virgin Galactic’s rocket plane.

In an August 13 SEC filing, Richard Branson, the English billionaire who founded Virgin Galactic in 2004, said that in the previous three days, he had sold roughly 10.5 million personal shares, a stake worth about $300 million.

Let’s review the timeline.

July 11: The flight occurs, with high winds forcing it outside its planned flight path.
July 12: Virgin Galactic sells $500 million in stock, without mentioning the anomaly.
July 16: By this date the company was required to inform the FAA of any anomalies during the flight.
July 23: The FAA initiates its investigation..
August 11: The FAA grounds Virgin Galactic.
August 13: SEC filing reveals Branson had sold $300 million in stock without mentioning the anomaly.
September 1: New Yorker article reveals investigation of anomaly.

Though no investigation had been started, Virgin Galactic must have known about the flight anomaly when it sold its $500 million in shares on July 12, right after the flight.. By August, when Branson sold his $300 million in shares, that investigation was on-going. Yet he also failed to mention the anomaly.

As I have said before, Branson has all the markings of a conman. He has very carefully been selling stock, reducing his share in the company in the past two years from 51% to 18%, with each stock sale carefully timed to take advantage of some event that pumped up the stock’s price.

All in all, the pattern by Branson suggests he really does not have much faith in Virgin Galactic’s future.

Rocket Lab negatively impacted by New Zealand’s Wuhan panic lockdowns

9:07 am

Capitalism in space? Rocket Lab reported this week that not only has its income been slashed because of New Zealand’s draconian lockdowns in fear of COVID-19, the company has had to cut its planned launches for the fourth quarter of 2021 by more than half.

“Operations have experienced disruptions due to some of the most restrictive COVID-19 measures globally, including current stay-at-home orders which prevent launch operations from taking place,” said Peter Beck, chief executive of Rocket Lab, of New Zealand’s current restrictions. “Indications are that the current lockdown restrictions may ease by the end of September with the delta cases dropping in New Zealand, but this, of course, is subject to change.”

Those restrictions have delayed plans by Rocket Lab to perform three dedicated Electron launches of BlackSky satellites that had been scheduled to begin in late August. It could also affect the launch of NASA’s CAPSTONE lunar cubesat, which had been scheduled for no earlier than late October on another Electron from Launch Complex 1 in New Zealand.

Adam Spice, chief financial officer, said that the company has five Electron launches manifested for the fourth quarter of the year, but is assuming only two launches in its financial projections. While those five launches would produce more than $40 million in revenue, the company is forecasting only $17-20 million in revenue for the fourth quarter.

Meanwhile, the company has not been able to launch from its new launchpad at Wallops Island in Virginia because NASA — after almost two years! — has apparently still not approved the company’s flight termination system, used to destroy a rocket that has gone out of control. NASA’s refusal to approve this system is very puzzling and very suspicious, especially because Rocket Lab has launched 21 times with it from New Zealand, and even used it several times to successfully destroy failing rockets.

Smoke and fire alarms in Russian ISS module Zvezda

8:54 am

In the middle of the night prior to a successful spacewalk by two Russian astronauts to begin the outfitting of the new Nauka module on ISS, fire alarms sounded in the Zvezda module, and both astronauts smelled smoke.

The incident, which the Russian space agency Roscosmos said happened at 1:55 a.m. GMT (9:55 p.m. EDT Wednesday) ahead of a scheduled spacewalk, is the latest in a string of problems to spur safety concerns over conditions on the Russian segment. “A smoke detector was triggered in the Zvezda service module of the Russian segment of the International Space Station during automatic battery charging, and an alarm went off,” Roscosmos said in a statement.

French astronaut Thomas Pesquet said “the smell of burning plastic or electronic equipment” wafted to the US segment of the station, Russian state news agency RIA Novosti reported, citing a NASA broadcast.

The Russian crew turned on a filter and, after the air was cleaned up, the astronauts went back to sleep, Roscosmos said.

It appears that because all the systems on the Russia portion of ISS continued to function normally, the Russians did no investigation. Or if they did, they have not revealed what they found. Nor has NASA provided any information.

In their history the Russians have experienced a number of fires on their various space stations. Some burned out without consequence (as it appears this recent one did). Others required aggressive action to bring them under control, as occurred on Mir several times. This history has apparently made the Russians somewhat nonchalant about such things.

That the issue was in Zvezda, however, which has a serious structural stress fracture problem in its hull, should be cause for a greater concern. Is this burn event related to the stress fractures? If I was an astronaut on board ISS I would surely want to know.
