Chinese pseudo-private rocket fails during launch

2:23 pm

A launch attempt by the pseudo-private Chinese company iSpace failed today, the second failure in a row for this company following a success.

A Hyperbola 1 rocket lifted off from the Jiuquan launch base at 3:39 a.m. EDT (0739 GMT; 3:39 p.m. Beijing time), China’s government-run Xinhua news agency said. Xinhua, which described the launch as a “flight test,” said the rocket exhibited “abnormal performance” after liftoff. Officials did not immediately specify when during the flight the rocket failed.

The news agency said a satellite carried by the rocket “did not enter orbit as scheduled.” Chinese officials did not identify the payload lost on the mission.

This is the second launch failure in a row, following the first successful orbital launch in July 2019.

The rocket is made of four solid-fueled stages, which means it most certainly is using military tecnology and is being closely supervised by the Chinese government. ISpace is one of about four such pseudo-private Chines companies. In each case, China is allowing private Chinese capital to finance the development of these rockets, for use both by the Chinese government as well as sale to customers (but only with the government’s approval and control).

Today’s blacklisted American: 65,000 Americans censored by social media

12:03 pm

The Bill of Rights cancelled by Google, Facebook, and Twitter
The Bill of Rights cancelled by
Google, Facebook, and Twitter.

The new dark age of silencing According to the legal team for former president Donald Trump, almost 65,000 people have submitted examples of censorship by the social media companies Google, Facebook, and Twitter, and the lawyers have amended Trump’s the lawsuit to add those individuals to it.

According to the America First Policy Institute (AFPI), Trump’s July 7 lawsuit against Facebook, Twitter, and Google is adding ”additional censorship experiences” from some of the nearly 65,000 people who submitted them to the institute. ”Late last night, Amended Complaints were filed in the Big Tech lawsuits against Facebook, Inc., Mark Zuckerberg, Twitter, Inc., Jack Dorsey, Google LLC, and Sundar Pichai,” AFPI said in a July 28 statement.

“Since the initial filing on July 7, 2021, nearly 65,000 American people have submitted their stories of censorship through America First Policy Institute’s (AFPI) Constitutional Litigation Partnership (CLP) at TakeOnBigTech.com,” AFPI added.

Curiosity’s wheels: a good news update

11:13 am

Curiosity's wheels
Click here and here for the original images.

For the past few weeks Curiosity has been traveling across some of the roughest terrain it has seen on Mars, since landing in Gale Crater in August 2012. The rover is now roving among the high cliffs and foothills at the very base of Mt Sharp, with the ground covered with rocks, boulders, plates of bedrock, and all sorts of protrusions.

On August 1st the rover team used its cameras to do another survey of the rover’s wheels to see how they fared during that journey. The two images to the right compare the same area on the same wheel after the most recent 16 sols of travel. This is the same wheel I have focused on since 2017. Overall, the damage in the most recent picture seems almost identical to the previous picture. In fact, if you compare today’s image with the annotated version of the 2017 photo, found here, you can see how little things have changed since then.

From this one wheel it appears that the wheels are continuing to hold up quite well. The Curiosity team of course needs to review all the images of all the wheels, but based on this one comparison, it looks like their long term strategies for mitigating damage to the wheels is working, even in the rough terrain the rover is presently traversing.

The annual July fund-raising campaign: Thank you!

10:05 am

This post will remain at the top of the page for the next few days. Scroll down for news updates and commentaries.

My July fund-raising campaign for 2021 has now ended. Thank you all for your donations and subscriptions. While this year’s campaign was not as spectacular as last year’s, it was the second best July campaign since I began this website. My gratitude cannot be expressed adequately.

As already mentioned, a handful of people have donated enough for a free ebook, but have not responded to my requests for which book they wish and in what format. I can’t give you this gift if you don’t tell me what you want. Will those individuals please email me the book and the format (epup or pdf) they desire?

I once again must express my gratitude to everyone for their support. No one is obliged to pay anything to read my website. That so many people are willing to give freely warms my heart, and gives me hope that I am not the only person left who believes in fearless exploration and freedom.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

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

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

 

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

 

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

 

Autographed printed copies are also available at discount directly from the author (hardback $29.95; paperback $14.95; Shipping cost for either: $6.00). Just send an email to zimmerman @ nasw dot org.

Martian lava flooded crater?

lava flooded crater?
Click for full image.

A quick cool image! The photo to the right, rotated, cropped and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) more than a decade ago, on June 1, 2010. I post it now because it is today’s MRO picture of the day, and is definitely cool. The caption:

One of a few “scaly-looking” inselbergs within regional platy-ridged flows in Elysium Planitia. This inselberg has a broken and blocky appearance with some of the blocks being tilted. Could this be the remnant of a once extensive mantling deposit? An inselberg is an isolated hill or mountain rising abruptly from a plain.

The wider image by MRO’s context camera below, also rotated, cropped and reduced to post here, illustrates even more forcefully how isolated this circular set of blocks is.

Two flybys of Venus set by two spacecraft on August 9th and 10th

8:54 am

Two European planetary probes, one launched to study the inner solar enviroment and the second to study Mercury, are going to fly past Venus only 33 hours apart on August 9th and 10th.

Solar Orbiter, a partnership between ESA and NASA, will fly by Venus on 9 August with a closest approach of 7995 km at 04:42 UTC. Throughout its mission it makes repeated gravity assist flybys of Venus to get closer to the Sun, and to change its orbital inclination, boosting it out of the ecliptic plane, to get the best – and first – views of the Sun’s poles.

BepiColombo, a partnership between ESA and JAXA, will fly by Venus at 13:48 UTC on 10 August at an altitude of just 550 km. BepiColombo is on its way to the mysterious innermost planet of the solar system, Mercury. It needs flybys of Earth, Venus and Mercury itself, together with the spacecraft’s solar electric propulsion system, to help steer into Mercury orbit against the immense gravitational pull of the Sun.

The two spacecraft will zip past a different side of Venus. For a variety of reasons, the imagery gathered will not of high resolution, though both spacecraft will gather data that will eventually be correlated with similar data being gathered by Japan’s Akatsuki probe, in orbit around Venus since 2015.

SpaceX installs 29 Raptor engines on Superheavy #4

8:45 am

Capitalism in space: SpaceX has now installed 29 Raptor engines on the fourth Superheavy prototype, intended to be the first to attempt an orbital launch, even as the company also prepares Starship prototype #20 for that flight.

In a marked increase to the already-impressive production cadence at SpaceX Starbase, it’s all hands on deck with Booster 4 and Ship 20 preparations ahead of the duo being sent to the launch site. Booster 4 was stacked on Sunday, with all 29 Raptors installed by Monday morning. While the orbital launch attempt is not imminent, the duo is expected to undergo a series of ground testing objectives, including multiple Static Fire tests for the booster. This will also provide time to complete the final elements of the Orbital Launch Site (OLS), from which the duo will conduct the milestone test flight.

Following a short ground testing campaign with Booster 3, which included cryo proofing and a three-engine Static Fire test, the focus is now on what will become the first integrated stack of a Super Heavy booster and a Starship vehicle. This is set to be achieved in double-quick time, following a call to arms from SpaceX to its workforce. This included the transportation of hundreds of workers from other sites in the country, as per a memo leaked on Facebook.

As predicted, SpaceX did not succeed in launching Superheavy/Starship on its first orbital test flight in August. However, as predicted the company is clearly pushing to attempt that flight before the end of the summer. Right now, based on the pace of operations, what has been accomplished, and what needs to be accomplished, I estimate that flight will likely occur sometime around late September to early October.

It also seems very obvious that SpaceX is trying very hard to beat SLS into orbit. If successful, it will underline most starkly the difference between free enterprise and government operations. The former got it done in about four years, for less than $6 billion. The latter has taken seventeen years, and about $60 billion, and has still not launched.

And even if SLS launches first, that contrast remains.

Starliner launch scrubbed; no launch date yet set

8:32 am

For reasons that have not yet been revealed, ULA scrubbed today’s unmanned demo test flight of Boeing’s Starliner capsule just prior to launch, rescheduling the launch for tomorrow.

The launch tomorrow wiill occur at 12:57 am (Eastern).

UPDATE: It appears the scrub occurred because of a valve issue in the propulsion system of Boeing’s Starliner capsule.

“During pre-launch preparations for the uncrewed test flight of the CST-100 Starliner spacecraft, Boeing engineers monitoring the health and status of the vehicle detected unexpected valve position indications in the propulsion system,” the company said in a statement. “The issue was initially detected during check outs following yesterday’s electrical storms in the region of Kennedy Space Center.”

…The propulsion system valves in question are inside the Starliner’s service module, which has an array of rocket thrusters designed to propel the spacecraft away from its launcher during an in-flight emergency. Other thrusters on the service module are used for in-orbit maneuvers and spacecraft pointing control.

Boeing cannot afford more failures during this second demo flight. The company has been plagued with numerous debilitating technical failures during the past four years, from Starliner to its airlines. Right now the failure to get Starliner operational is losing them business in the emerging orbital tourist market. They need to get it working, and working reliably.

UPDATE: They have decided to cancel the launch plans for tomorrow, to roll the rocket back into the assembly building so they can do more tests on the capsule’s service module where the troublesome valves are.

Nauka shook up ISS more than first revealed

9:50 pm

According to new reporting, when the new Russian module Nauka unexpectedly began firing its engines, it rotated the International Space Station far more than first revealed, requiring a much more complicated effort to bring the station back to its correct orientation.

Zebulon Scoville, the flight director at NASA mission control in Houston, revealed that the 45 degrees that was initially reported as the amount ISS rotated was incorrect.

According to Scoville, the event has “been a little incorrectly reported.” He said that after Nauka incorrectly fired up, the station “spun one-and-a-half revolutions — about 540 degrees — before coming to a stop upside down. The space station then did a 180-degree forward flip to get back to its original orientation,” according to the report.

Scoville also shared that this was the first time that he has ever declared a “spacecraft emergency.”

It appears that though the station spun far more than first reported, the rate of rotation was still relatively slow, so it apparently did no harm to the station.

Scoville also revealed that, based on the data on hand during the event, it appeared Nauka was also trying to undock itself from the station. Mission controllers tried to counter this by firing engines on a Russian Progress freighter as well as on the Zvezda module.

Had Nauka’s engines had not stopped firing (for unknown reasons, though probably because they ran out of fuel), there was the real chance the accelerations could have shaken the station apart. Moreover, that other engines were brought into play suggests that the Russians not only did not know why Nauka’s engines fired, they had at the time no way to shut them down, and were thus forced to improvise other actions to try to save the increasingly dangerous situation.

The sublimating surface of Mars’ northern plains?

3:30 pm

Sublimating patches on Mars?
Click for full image.

Cool image time! The photograph to the right, cropped and reduced to post here, was taken by the high resolution camera on Mars Reconnaissance Orbiter on May 27, 2021. A sample image, likely taken not as part of any specific scientist’s research but by the camera team in order to maintain the camera’s temperature, shows an area of the Martian northern plains that appears filled with rough scattered depressions, possibly caused by sublimation of buried ice.

The location, at 54 degrees north latitude, is far enough north to easily have a lot of buried ice. It is also only about 40 miles to the east of Milankovič Crater, where scientists have found many scarps that appear to have exposed layers of ice in their cliff faces.

However, the location has other components that must raise questions about this sublimating ice hypothesis.

Upcoming Zimmerman public lecture available for all – Last Call!

10:40 am

Tomorrow I will be giving a lecture on the Artemis Accords to the Arizona Space Business Roundtable, a monthly event in Tucson, founded by space businessman and local all-around good guy Stephen Fleming, to bring together the business-oriented space community of this city and southern Arizona.

From Stephen Fleming’s announcement:

Bob has spoken to the Roundtable before; this time, I’ve asked him to focus on the Artemis Accords… the USA’s attempt to “to create a safe and transparent environment which facilitates exploration, science, and commercial activities for all of humanity to enjoy.” What does that mean? It’s an attempt to break the international logjam that has blocked the private sector development and exploitation of resources on the Moon, asteroids, and other celestial bodies. How is it working, who has joined on, and what does China think about all this? Come find out from Bob!

The event will be open to the public, no charge, and will also be available on Zoom. It is scheduled for Tuesday, August 3, 2021, from 5:00 — 6:30 pm (Arizona time, which presently corresponds to Pacific time).

If you wish to come in person, the event will be at 110 E. Pennington St, Room 215, in Tucson.

If you want to attend via Zoom, you will need to express your interest as a comment below, and I will then email you the Zoom url and password. We are not publishing this information publicly to avoid a hacking during the event.

Let me repeat: You need to express an interest in attending by Zoom by posting a comment. Otherwise you will not get the password and will not be able to watch. (I will send out the password tomorrow to all those in the comment thread.)

If you are coming in person Stephen would appreciate it if you say so in a comment below also, so that he can estimate a count. He provides, out of his own pocket, cookies and coffee for in-person attendees, and needs to gauge how much to provide.

Note that I have written these essays previously about other Arizona Space Roundtable events:

Sunspot update: Another month of greater activity than predicted

10:11 am

NOAA this past weekend released an 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 July the Sun’s hot streak of sunspot activity continued. The number of sunspots on its visible hemisphere continued to exceed the prediction of NOAA’s solar science panel, with the numbers in July easily topping June’s numbers. Only at the very end of July was there a streak of five blank days, the first time the Sun has been blank of sunspots since May 6th, a stretch of activity not seen for years, since the last solar maximum was ramping down to solar minimum in ’16-’17.

The political consequences of this continuing high activity could be quite profound.

Zhurong continues south, inspecting dunes

10:40 am

Zhurong's travels as of July 31, 2021

The Chinese science team for their Zhurong Mars rover released new images yesterday, including a map showing the rover’s present position.

The new images and location has confirmed that the white streaks seen in orbital pictures are small dunes of sand blown by the thin Martian wind.

The map to the right, created using their map but annotated and providing a wider context, shows their present location relative to the lander and surrounding terrain. So far the rover has traveled about 1,900 feet, about 1,000 feet per month. Since it seems to be operating as planned, I expect China will extend the mission once it completes its nominal three-month tour in about two weeks.

At that travel pace there is much of interest that is within the rover’s range. I expect they are heading south partly because this brings them closer to their original landing site, which is an area they probably studied at length before landing. Whether they head to the largest crater, visible only partly on the image’s south edge, remains unclear.

Russia offers conflicting causes for Nauka engine firing

9:34 am

Russian officials have now suggested two explanations for the accidently ignition of the engines on the new Nauka module to ISS, neither of which appears to have involved any real investigation.

Vladimir Solovyov, flight director of the space station’s Russian segment, blamed the incident on a “short-term software failure.” In a statement released Friday by the Russian space agency Roscosmos, Solovyov said because of the failure, a direct command to turn on the lab’s engines was mistakenly implemented.

He added the incident was “quickly countered by the propulsion system” of another Russian component at the station and “at the moment, the station is in its normal orientation” and all its systems “are operating normally.”

Roscosmos director Dmitry Rogozin later Friday suggested that “human factor” may have been at play. “There was such euphoria (after Nauka successfully docked with the space station), people relaxed to some extent,” Rogozin said in a radio interview. “Perhaps one of the operators didn’t take into account that the control system of the block will continue to adjust itself in space. And it determined a moment three hours after (the docking) and turned on the engines.” [emphasis mine]

So, was it human error? Or was it the software programming? Or both?

No matter what the specific cause, these conflicting stories, thrown out in almost an offhand manner, demonstrate that the real fundamental cause was the terrible, sloppy, and error-prone quality control systems at Roscosmos and all the aerospace companies it has taken over since the Putin administration consolidated Russia’s aerospace industry into a single government-run corporation.

These kinds of failures seem to happen with Russia now repeatedly. From launch aborts to launch failures to corruption in contracting to corruption in engine construction to plain simple sabotage, mistakes and errors and poor planning and dishonesty seem to hound their space effort at every level. Thank God Americans no longer have to fly on a Soyuz capsule, though one American on board ISS is still scheduled to come home on one.

Without competition and freedom, there is no pressure in Russia to improve, to improvise, to rethink, and to clean house when a management gets stale or corrupt. Instead, operations stultify and develop dry rot. They can’t see problems or even fix them efficiently. If anything, management circles the wagons to protect itself, while often deliberately ignoring the problems.

Rocket science is hard. It can quickly kill people when done poorly.

I think it will be a great relief to end this partnership. And the sooner the better.

GAO rejects protests by Blue Origin and Dynectics over lunar lander award

12:50 am

The Government Accountability Office (GAO) today rejected the protests by Blue Origin and Dynectics against the award by NASA of its manned lunar lander contract to SpaceX’s Starship spacecraft.

In denying the protests, GAO first concluded that NASA did not violate procurement law or regulation when it decided to make only one award. NASA’s announcement provided that the number of awards the agency would make was subject to the amount of funding available for the program. In addition, the announcement reserved the right to make multiple awards, a single award, or no award at all. In reaching its award decision, NASA concluded that it only had sufficient funding for one contract award. GAO further concluded there was no requirement for NASA to engage in discussions, amend, or cancel the announcement as a result of the amount of funding available for the program. As a result, GAO denied the protest arguments that NASA acted improperly in making a single award to SpaceX.

GAO next concluded that the evaluation of all three proposals was reasonable, and consistent with applicable procurement law, regulation, and the announcement’s terms.

Finally, GAO agreed with the protesters that in one limited instance NASA waived a requirement of the announcement for SpaceX. Despite this finding, the decision also concludes that the protesters could not establish any reasonable possibility of competitive prejudice arising from this limited discrepancy in the evaluation.

This decision will likely allow NASA to proceed with the contract, and for SpaceX to begin work on the revisions it will need to make to Starship to make it a lunar lander.

The decision also puts companies like Blue Origin and Dynectics on notice: You need to prove you have the goods, or you won’t win customers. Commit some of your own funds to research and development, start building actual prototypes you can test, and the world will begin to beat a path to your door.

Arianespace successfully completes first Ariane 5 launch in almost a year

11:23 pm

Arianespace today successfully completed its first Ariane 5 launch since August 2020, placing in orbit two commercial communications satellites.

The long gap in launches occurred because of a vibration issue discovered during that August 2020 launch durng the release of the rocket’s two fairing halves.

Engineers introduced modifications to the Ariane 5’s payload fairing, or nose cone, to reduce vibrations imparted on the satellites during separation of the shroud, which protects payloads during the first few minutes of flight through the atmosphere. Ground teams will analyze data from the rocket to make sure the changes reduced the vibrations.

Another launch is scheduled for September, followed next by the launch of the James Webb Space Telescope in either November or December. The results from today’s launch as well as the one in September will determine if the Webb launch will go forward on time.

These issues with Ariane 5, delays imposed by the company in fear of the Wuhan flu, and other launch problems with Arianespace’s Vega rocket, has meant that this is only its second launch in 2021, a pace that is below its pace for most of the last decade. Whether the company can recover and pick up the pace before the end of the year will depend on what they learn during today’s launch.

With only two launches total, Europe’s Arianespace remains off the leader board in the 2021 launch race:

24 China
20 SpaceX
12 Russia
3 Northrop Grumman
3 Rocket Lab

The U.S. lead over China in the national rankings remains 30 to 24.

Peter, Paul and Mary – Don’t Ever Take Away My Freedom

6:01 pm

An evening pause: A nice intro to the weekend as well as a fitting closing to my July fund-raising campaign. Strangely, there are no live performances of this song by Peter, Paul, & Mary available on the web. Could it be that they themselves became uncomfortable with its sentiments in later years, being hardcore leftists? I wonder. Consider the lyrics:

[Third verse]
Now when I’m old and thinking over the life that I’ve led
If there’s one final wish left to me
I will pray for the children yet to be born
I will pray that they will always live free

[Chorus]
Don’t ever take away their freedom
Don’t ever take it away
Let us cherish and keep that one part of our lives
And the rest we’re gonna find one of these days

These are not the sentiments of most leftists today. The last thing they want is freedom for all. What they want now are mandates, edicts, rules, regulations, and a boot smashing the face of all humans, forever, in the guise of a muzzle.

Note also that the song opens with Home on the Range, which is how PP&M originally recorded for their album, Peter, Paul, & Mommy Two.

Today’s blacklisted American: Town tries to silence Trump supporter; he sues

2:05 pm

Banned for being conservative
No first amendment rights in Long Beach, New York!

The modern dark age: Because the town of Long Beach, New York has forced a Trump supporter to hide his car, festooned with pro-Trump and conservative messages, he is suing that town for $25 million for denying him is first amendment rights.

“I believe the city is trying to silence me because I’m pro-Trump,” [Michael Wasserman] told The Post. The 62-year-old entrepreneur has become known in the area for plastering his home — along with his Porsche and Jeep — with a rotating variety of political flags and stickers.

Now he has filed a $25 million federal suit — against the City of Long Beach, the chief of police, the city manager and specific police officers — after officials forced him to remove the flags on his cars.

The town claims they are a violation of an ordinance stating that “[No] sign shall be erected, affixed or maintained within the perimeter of any … public street or public property.” Wasserman parks his car on a public street outside his home.

“They’re bending and massaging the ordinance to fit the crime,” Wasserman told The Post. “This is a blatant attempt to silence me.”

The picture above shows Wasserman leaning on his car, with his home behind him, also covered with flags and political banners.

The city claims they are simply enforcing a law that forbids signage without permission on public streets. Yet, how are the signs on Wasserman’s car any different then every bumper sticker you see? They are not, and this is where Wasserman’s claim that it is pure political oppression seems confirmed.

Wasserman’s case is further reinforced by the treatment he gets generally in this blue-state New York town:

Apollo: When Americans last did some real exploring

1:02 pm

The journey of Apollo 15 on the Moon
Click for full image.

Today is the fiftieth anniversary of the landing of Apollo 15 on the Moon. To commemorate that event the science team for Lunar Reconnaissance Orbiter (LRO) today published some orbital images that capture the astronauts’ travels while on the Moon. The picture to the right, reduced to post here, outlines in oblique view their various excusions to the edge of Hadley Rille and the foot of a mountain dubbed Hadley Delta. As they note,

While Apollo 15 was the fourth mission to land a crew successfully on the lunar surface, it still pioneered many new technologies and had many firsts.

Some of the technologies developed for Apollo 15 included new suits, which were more flexible and had longer life support capabilities, as well as the Lunar Roving Vehicle (LRV), a rover capable of speeds up to 15 km / hour. With these advancements, astronauts Commander David (Dave) Scott and Lunar Module Pilot James (Jim) Irwin were able to travel more than eight times the distance traveled during the previous mission, for a total of over 25 km.

All told, astronauts Dave Scott and Jim Irwin spent more than 18 hours exploring the lunar surface on three scouting trips, covering 15.5 miles. During all those excursions their only protection from the harsh lunar environment was that thin spacesuit. In addition, if their rover broke down a walk back to the lunar module would become a race against suffocation.

And even then, they still had to get that lunar module off the ground, rendezvous and dock with the Apollo 15 command module, and then get that module back to Earth safely.

United Kingdom passes comprehensive spaceflight regulations

10:39 am

Capitalism in space: As required by the Outer Space Treaty as well as to lay a framework for commercial and private space launches from within the United Kingsom, the UK this week passed new comprehensive spaceflight regulations that appear modeled closely after already existing regulations in the United States.

From the government’s press release:

The legislation provides the framework to regulate the UK space industry and enable launches to take place from British soil for the very first time. It will unlock a potential £4 billion of market opportunities over the next decade, creating thousands of jobs and benefiting communities right across the UK.

This also puts the UK in a unique position as the first country in Europe able to launch spacecraft and satellites from home soil. This could lead to better monitoring of climate change, as well as improved data for satellite navigation systems, improving journeys right here on the ground, too.

The full law can be read here. It is long, so I have not reviewed it entirely, but it does seem to be closely modeled after several U.S. laws, including the 2004 Space Amendments Act that presently guides FAA regulation and licensing of commercial space launches. The UK even gave its own Civil Aviation Authority (CAA) the same job the FAA has in the U.S.

Capitalism in space: Inmarsat announced yesterday that it plans to launch a 150 satellite constellation in low Earth orbit to supplement and improve its already orbiting communications satellites in high geosynchronous orbit.

The company is investing $100 million over the next five years to lay the groundwork for deploying 150-175 LEO spacecraft.

They aim to join satellites Inmarsat has in geostationary and highly elliptical orbits from 2026. Inmarsat, which currently operates 14 satellites, is also on track to add five new GEO and two HEO spacecraft to its network over the next five years.

Its incoming multi-orbit constellation, called Orchestra, seeks to improve latency, network speeds and resiliency for communications services across its core maritime, aviation, government and enterprise markets.

This new constellation is also an effort by Inmarsat to keep its communications product competitive against the newer constellations being launched by SpaceX (Starlink) and OneWeb.

For the space launch industry, this just means more launches, more demand for rockets, and more money to be made.

Note that Inmarsat’s approach here is the correct way to respond to competition. Rather than try to squelch your competitors using government regulation, as Viasat is attempting, Inmarsat is instead up its game, improving its product, and thus matching the challenge its competitors are offering it.

One last question: Will this new constellation, set to be operational by ’26, get there before Amazon’s long promised Kuiper constellation? Right now I’m willing to bet that it will, considering how slow Amazon has been in developing that system.

Apollo 11 lunar ascent stage might still be in orbit around the Moon

10:10 am

New data about the Moon’s interior and gravitational field suggest that the Apollo 11 lunar ascent stage, the part of the LM that carried the astronauts back from the Moon, might still be in orbit around the Moon, rather than have crashed into its surface as long assumed.

Using the GRAIL gravity model and the General Mission Analysis Tool (GMAT) simulator, Meador expected to find the LM’s orbit destabilizing very quickly. What he found – and was verified by a third party using different methods – was that the Ascent Stage had a feedback mechanism that caused the orbit to stabilize itself over a period of every 24 days. When he ran the simulation forward, the orbit remained stable until the present day.

The upshot of this is that the Ascent Stage may still be in orbit now and could be observed when it is in the right position in relation to the Earth and the Sun. However, Meador emphasizes that the LM was never intended to be very robust. Designed to operate for only about 10 days, it was also filled with batteries and fuel tanks, which could have exploded years ago, either destroying the craft or sending it off on a new trajectory.

If the stage is in lunar orbit, than it probably is one the most valuable and quickly reachable artifacts from one of space’s most historic missions. While the Apollo artifacts left on the Moon should be left where they are, this piece could be recaptured and returned to Earth for both study and exhibition.

In fact, if it is still in orbit it should be recovered, to preserve it.

This data also suggests that other Apollo ascent stages as well as other past lunar orbiters might also still be in lunar orbit, and should be located.

Nauka engines fire unexpectedly after docking; forces cancellation of Starliner launch

1:20 pm

The soap opera of the Nauka module to ISS became even more dramatic today when its engines fired unexpectedly after its docking, causing the station to shift in orbit and forcing Russian mission controllers to shut it down and fire other engines to return the station to its proper orbit.

Russia’s Roscosmos space agency attributed the issue to Nauka’s engines having to work with residual fuel in the craft, TASS news agency reported. “The process of transferring the Nauka module from flight mode to ‘docked with ISS’ mode is underway. Work is being carried out on the remaining fuel in the module,” Roscosmos was cited by TASS as saying.

It appears that because they needed to improvise the rendezvous using different engines, there is more fuel left over in Nauka than expected once it docked, and this needs to be vented safely. Somehow, instead of venting the module ignited the engines.

NASA has subsequently postponed tomorrow’s second unmanned demo launch of Boeing’s manned Starliner capsule until the agency has a clear understanding of the issue and has confirmed that Nauka’s presence is not a serious safety issue.

The view from Ingenuity during 10th flight
Click for full image.

Cool image time! Today the Perseverance science team released the 200 images that Ingeniuty took during its 10th flight on July 24, 2021.

The photo to the right was taken about 25 seconds before the helicopter landed, and looks to the southwest. In the foreground can be seen the ridge of rocks and pebbles that the scientists sent Ingeniuty to photograph. In the distance can be seen the rim of Jezero Crater, about 7.5 miles away, with some rounded hills that sit in the crater floor about 5.5 miles away.

The white box indicates the area covered by two high resolution images taken by Perseverance on July 28th that I have combined into the panorama below.

Atomic oxygen in Mars’ atmosphere, as seen by Al-Amal

12:06 pm

Oxygen distribution on Mars

The UAE’s Al-Amal Mars orbiter on July 19, 2021 released a new spectroscopic image, showing the global distribution of atomic oxygen in the Martian upper atmosphere.

The Emirates Ultraviolet Spectrometer (EMUS) mapped the distribution of atomic oxygen in the planet’s upper atmosphere, showing a dense patch emerging from the nightside into the new day.

The photo to the right, cropped and reduced to post here, shows this.

Over the next two years, covering one single Martian year, Al-Amal will monitor the distribution of this oxygen to see how it fluctuations from season to season, as well as from day to day. Gather this information will help the theorists untangle the past atmospheric history of Mars.

Today’s blacklisted American: Democrat endorses racial discrimination and press censorship aimed at whites

11:36 am

Discriminated against by Chicago Democrats
Eagerly discriminated against by Democrats

Blacklists and segregation are back and the Democrats have got ’em: Lori Lightfoot, the Democratic Party mayor of Chicago, recently and enthusiastically defended her past racial disciminatory policy of refusing to give any one-on-one interviews to white reporters, saying she intends to do it again.

Chicago Mayor Lori Lightfoot said she would “absolutely” grant interviews only to journalists of color again after she drew waves of backlash earlier in the year when she announced the policy.

“I would absolutely do it again. I’m unapologetic about it because it spurred a very important conversation, a conversation that needed to happen, that should have happened a long time ago,” the Democrat said on a segment of the New York Times’s podcast Sway, released on Monday.

“Here is the bottom line for me: To state the obvious, I’m a black woman mayor,” she said. “I’m the mayor of the third-largest city in the country. Obviously, I have a platform, and it’s important to me to advocate on things that I believe are important. Going back to why I ran — to disrupt the status quo. The media is critically important to our democracy. … The media is in a time of incredible upheaval and disruption, but our City Hall press corps looks like it’s 1950 or 1970.”
