NASA reveals technical problem during solar sail deployment of test mission

9:32 am

NASA today revealed that a technical problem occurred during the deployment of a demonstration solar sail mission launched in April on Rocket Lab’s Electron rocket.

Upon an initial attempt to unfurl, the solar sail paused when an onboard power monitor detected higher than expected motor currents. Communications, power, and attitude control for the spacecraft all remain normal while mission managers work to understand and resolve the cause of the interruption by analyzing data from the spacecraft.

The goal had been test the boom deployment of a 860 square foot sail from a cubesat only about 4 feet in size.

The concept of the solar sail is simple: Use the pressure produced by sunlight to maneuver and fly controlled throughout the solar system. The idea has been tested successfully several times, with the Japanese IKAROS test solar sail and the Planetary Society’s Lightsail-2 the most successful. Sadly almost all other attempts to test this idea have had technical problems of one kind or another.

Ironically, one test solar sail proved that such a deployment from a cubesat could be done very cheaply, unlike NASA’s effort above. Brown University students in 2023 used cheap off-the-shelf parts to launch a smallsat sail that successfully deployed and was then used to lower the satellite’s orbit in order to de-orbit it more quickly. Total cost, $10,000. And it worked.

Genesis cover

On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.

 

The print edition can be purchased at Amazon, any other book seller, or direct from my ebook publisher, ebookit. The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.


The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
 

"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

Launch of Jared Isaacman’s second spaceflight scheduled for tonight

4:10 pm

The real rocket behind tonight's launch
The real rocket behind tonight’s launch

UPDATE: The launch tonight was scrubbed due to a helium leak in a “ground side umbilical disconnect.” SpaceX is now targeting Wednesday, August 28 at 3:38 AM (Eastern) for the next launch attempt.
Original post:
———————–
At 3:38 am (Eastern) tonight, SpaceX’s will attempt the launch of the Polaris Dawn mission carrying billionaire Jared Isaacman (on his second spaceflight) and three other private passengers (two of which are SpaceX employees), its Falcon 9 rocket lifting off from the Kennedy Space Center in Florida carrying the Resilience capsule on its third flight.

I have embedded a live stream of the launch below. SpaceX says it will begin 3.5 hours before launch. For those on the west coast the timing is reasonable. East coasters will have to do without sleep tonight if they wish to watch.

The mission’s main engineering goal during its five-day duration is to complete the first all private spacewalk using EVA suits developed by SpaceX. Two of the crew will exit the capsule, but all four will be in the suits because the capsule has no airlock and will be entirely vented of air during the spacewalk. The mission’s secondary goal (which it actually will do first) will be to raise the orbit to about 870 miles, the highest orbit for a manned flight since the Apollo missions in the 1970s. During that high orbit the crew will do radiation research, which they will continue after the orbit is lowered. More information about the mission goals can be read here.

The mission’s real goal however has nothing to do with engineering and everything to do with freedom and the American dream. This is an entirely private mission. The rocket is privately built. The capsule is privately built. The launchpad is privately built. The launch crew is privately employed. The astronauts are all private citizens, with one paying the way for the entire flight and two flying as employees of SpaceX to test the operation of its capsule in orbit.

No government money is involved. The government had little or no say on what will happen. The mission will illustrate in very stark terms what the American dream is all about, since it has been conceived, paid for, and created entirely by private citizens following their own dreams and goals.

Hail to freedom! May the bell of liberty always ring.

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.

The fall of DEI accelerates

12:50 pm

Are Americans finally waking up and emulating their country's founders?

Fight! Fight! Fight! In the past two months it has become very clear that if Americans are willing to stand up to the left and its Marxist bigoted agenda, Americans will win.

Since late June, five different university systems have shut down their Diversity, Equity, and Inclusion offices. Each is listed below, in chronological order:

And this list does not include the University of Florida, which in March shut down its own DEI office because the state legislature not only banned such offices, it cut the budgets of them.

Though it is true these states are all solidly conservative with legislatures largely controlled by Republicans, this fact on its face proves that voting can make a difference, with Florida the biggest proof. Unlike the other states, Florida had for decades been a swing state between the Democrats and Republicans. Voters however changed that in the past decade, so that today the state legisilature is solidly Republican. The result has been a definitive policy shift acting to eliminate these racist Marxist programs from state-financed universities.

There is no reason similar changes cannot be forced in other battleground states. Nor should we consider it impossible in the coastal states (California, Oregon, Washington, New York, Massachusetts, etc) where Democrats maintain full control. DEI concepts are inherently racist and divisive, and serve only to encourage anger, resentment, and hate across all ethnic groups. Ordinary voters recognize this routinely, when they make the effort to look.

Nor are things changing solely in the unversities because of the willingness of voters to force change. The boycott of Bud Light because of its endorsement of the queer agenda last year is having profound impact on corporate culture. In just the last few months a number of major companies have announced the elimination of their own DEI departments and programs, also listed below in chronological order:

The first three stories are from NPR and CNN, which explains the effort of the headlines to blame the evil “pouncing” of conservatives for this action (thus also implying that conservatives are bigots) . In truth, what these leftist news outlets refuse to recognize is that DEI programs are bigoted by their very nature, designed to favor some races over others merely because of skin color. These programs thus violate numerous civil rights laws, not to mention basic human morality and fair treatment. In addition, it appears the customers of all these companies, not simply conservatives, made it clear they would stop buying these products if company management did not take action to shut down these DEI policies.

Faced with a public backlash and the real threat of lawsuits and legal action against them, these companies are now recognizing that it makes no sense legally, financially, and morally to promote such things.

Trump defiant after being shot
Trump defiant

Increasingly, Americans are no longer willing to make believe that DEI and Marxism has a rightful place on the intellectual landscape. These ideas are garbage and downright evil, and it is a great tragedy that American academia allowed them to flourish on campuses for the past half century. The public is now beginning to make it clear that such ideas need to be sent to the ash heap of history, and legislators, academic administrations, and corporate managements are being forced to listen.

The trend is very obvious. If people actually pay attention and make it clear they will no longer tolerate the imposition of these bigoted leftist policies, those policies can be canceled and eliminated. One simply has to have the courage to fight, as Donald Trump said with such defiance immediately after getting shot.

A real whirlpool in space

9:52 am

A real whirlpool in space
Click for original image.
Cool image time! The picture above, cropped to post here, was taken by the Hubble Space Telescope as part of a survey of nearby galaxies that have what astronomers call an Active Galactic Nuclei (AGN), because the supermassive black hole at the center is devouring nearby material at a great rate and thus producing high energy emissions as it does so.

Many active galaxies are known to astronomers at vast distances from Earth, thanks to the great brightness of their nuclei highlighting them next to other, dimmer galaxies. At 128 million light-years from Earth, UGC 3478 is positively neighbourly to us. The data used to make this image comes from a Hubble survey of nearby powerful AGNs found in relatively high-energy X-rays, like this one, which it is hoped can help astronomers to understand how the galaxies interact with the supermassive black holes at their hearts.

The bottom line is that this spiral galaxy literally is a whirlpool, the entire galaxy spiralling down into that massive black hole in its center. One cannot help wondering why such galaxies don’t end up eventually getting completely swallowed by that black hole.

Or maybe they do, and we don’t see such things because all that is left is a supermassive black hole that emits no light or energy at all, a dark silent ghost traveling between the galaxies unseen and undetectable.

First high resolution images released from Juice’s fly-by of the Earth & Moon

9:34 am

Juice's high resolution view of the Moon
Click for original image.

The Italian science team that runs the high resolution camera on the asteroid probe Juice have now released that camera’s first images, taken to test its operation during the spacecraft’s close fly-by of both the Moon and then the Earth a week ago.

The picture to the right, cropped, reduced, and sharpened to post here, shows the Moon’s surface during that close fly-by, which got within 435 miles. The camera is dubbed Janus, and was developed by Italy and operated by the Italian National Institute for Astrophysics.

JANUS will study global, regional and local features and processes on the moons, as well as map the clouds of Jupiter. It will have a resolution up to 2.4 m per pixel on Ganymede and about 10 km per pixel at Jupiter.

The main aim of JANUS’s observations during the lunar-Earth flyby was to evaluate how well the instrument is performing, not to make scientific measurements. For this reason, JANUS took images with various camera settings and time intervals – a bit like if you’re going out to test a DSLR camera for the first time. In some cases, researchers intentionally ‘blurred’ the images so that they can test out resolution recovery algorithms. In other cases, they partially saturated the image to study the effects induced on the unsaturated areas.

As can be seen by the sample image above, the test images appear to have demonstrated that Janus will function as planned when Juice arrives in orbit around Jupiter in 2031 in order to study that gas giant’s upper atmosphere as well as its larger icy moons, Ganymede, Calisto, and Europa.

JAXA finally shuts down SLIM operations after four months of no contact

9:14 am

SLIM's last image
Click for original image.

Japan’s space agency JAXA today announced that it has now closed down all further attempts to contact its SLIM lunar lander on the surface of the Moon.

The Japan Aerospace Exploration Agency (JAXA) concluded operations of the Smart Lander for Investigating Moon (SLIM) on the lunar surface at 22:40 (JST), on August 23, after being unable to establish communication with the spacecraft during the operational periods from May to July*, following the last contact on April 28, 2024.

SLIM was launched onboard the H-IIA Launch Vehicle No.47 (H-IIA F47) on September 7, 2023 from the Tanegashima Space Center and achieved Japan’s first Moon soft landing on January 20, 2024. The landing precision was evaluated with a position error of approximately 10 meters from the target point, confirming the world’s first successful pinpoint landing. In addition, the Multi-Band Camera (MBC) successfully performed spectral observations in 10 wavelength bands on 10 rocks, exceeding initial expectations. Further, despite not being part of the original mission plan, the spacecraft was confirmed to survive three lunar nights and remained operational, demonstrating results that surpassed initial goals.

The lander’s main goal was to demonstrate the ability to do a precise robotic landing within a 100 meter landing zone. And even though one nozzle fell off during landing, resulting in SLIM landing on its side, it accomplished that goal and then survived three lunar nights, exceeding significantly its expected ability to function in harsh lunar environment.

The image to the right, reduced to post here, was taken by SLIM just before it was shut down for its first lunar night. It looks to the southeast across the width of 885-foot-wide Shioli Crater, the opposite rim the bright ridge in the upper right about a thousand feet away.

Rocket Factory Augsburg releases footage of 1st stage failure during static fire test

9:03 am

The German rocket startup Rocket Factory Augsburg today released the film footage it took during the failed 9-engine static fire test of its 1st stage last week.

I have embedded that footage below.

As the company’s CEO noted two days ago, the company has identified the cause as a fire in an oxygen pump which they think was unrelated to the engine design. This explanation remains puzzling, however. If the problem was not engine design, it suggests instead some other quality control error, which it is even more important to identify in order to prevent such errors in the future.

The video provides numerous angles of the failure, including one that captured the moment when the first stage fell over. As the CEO noted, it fortunately fell in the right direction, missing critical launchpad equipment and thus reducing significantly the damage to the pad.

Starliner will return unmanned; crew will return in February 2025 on Dragon

10:51 am

Starliner docked to ISS
Starliner docked to ISS.

In a briefing today, NASA’s administrator Bill Nelson announced that Boeing’s Starliner capsule, launched in June on its first manned mission, will return unmanned and that the two astronauts it brought to ISS — Butch Wilmore and Suni Williams — will return in February 2025 as part of the crew of the next Dragon manned mission, scheduled to launch in late September.

Nelson made it a point to note that NASA’s past inactions to protect astronauts on two different shuttle missions, thus leading to their deaths, was a factor in this decision. The agency now decided safety must come first, and since Starliner’s return abilities still carry uncertainties that relate directly to safety, it decided to use a more reliable and tested Dragon capsule to return those astronauts back to Earth. During the entire briefing and Q&A session it became very clear that NASA is now paying very close attention to its engineers and their conclusions, rather than dismissing those conclusions because of other management concerns, as it did during those previous two shuttle failures.

Nelson also stated that NASA still wants to use Starliner as a second crew vehicle to ISS. He noted that he has spoken to Boeing’s new CEO, who apparently committed to getting Starliner fixed and operating. It remains undecided whether another test manned flight will be required of Boeing (at Boeing’s cost) before NASA certifies it as an operational vehicle. Whether any other customers will be willing to use the capsule remains unlikely until Boeing has flown a lot of Starliner NASA flights with no problems.

At this moment they are looking to bring Starliner back in early September, using a simplified undocking system to get the vehicle away from ISS quickly. The next Dragon mission will launch no earlier than September 24th carrying two astronauts and two empty flight suits that Wilmore and Williams use during their return.

Update from Rocket Factory Augsburg’s CEO on first stage explosion on launchpad

9:26 am

Link here, but I have embedded his video statement below. He goes into detail about what they now believe happened when the rocket exploded during the static fire test, as well as the limited damage to the launchpad. They do not think the failure was a design flaw, which means it was caused by something that was done while building the engine. The company now plans to use for this first launch the stage that it was building for its second launch, and hopes to launch next year.

There was one little quote from him that tells me the company’s statement prior to the failed test that it could launch “in a matter of weeks” was based solely on its own engineering but was not going to happen. In today’s statement he says, almost as an aside, that “We wanted to launch in the next few weeks or months and this is unfortunately no longer possible.” [emphasis mine]

What the highlighted words tell me is that had this test been successful, Rocket Factory would have been able to stack the rocket and would have been willing to launch quickly. For that schedule to extend into months however could only be for one reason, an expectation that the UK’s Civil Aviation Authority (CAA) would not issue the launch license immediatley, but would dither as it did with Virgin Orbit (bankrupting that company).

Thus, red tape remains a major obstacle for the next launch. I suspect the CAA — risk adverse as all bureaucracies are — will not be comfortable issuing a new license after this failure, unless Rocket Factory can show unequivocally that it has taken actions that will prevent all such failures in the future, something that is likely impossible.

Blue Origin delays first New Glenn launch two weeks to October 13, 2024

9:04 am

The first launch of Blue Origin’s new New Glenn orbital rocket, carrying two Rocket Lab Mars orbiters built for NASA, has now been delayed two weeks to October 13, 2024.

The decision was made public by a very short and vague press release by NASA that stated no reasons for the delay and did not say clearly who made the decision. The release also did not indicate the launch window for this mission. The mission is going to Mars, which means it must launch within a certain clearly degined period this fall, when orbital mechanics will allow the orbiters to reach Mars as planned, or the mission will get delayed two years.

Blue Origin had previously targeted September 29, 2024 for the launch, but I have not been able to locate any source that states when that launch window ends. The delay of two weeks definitely shortens that window, but I don’t know how much.

Can Blue Origin meet this window? That remains unknown, but we shall soon find out.

  • Mynaric’s manufacturing woes threaten to delay production of U.S. military satellites

    • The German company is to supply the optical terminals that the satellites will use to send and receive laser signal, and its contract involves supplying these terminals to four other companies in their contracts with the Pentagon. It apparently is having problems scaling up the production of these units from making a few to many in order to serve a plethora of constellations.

Robert Kennedy’s speech today, in which he suspends his campaign and endorses Trump

2:12 pm

Even Robert Kennedy agrees with this now
Even Robert Kennedy agrees with this now

Below I have embedded in its entirety Robert Kennedy Jr.’s speech today where he announced he has suspended his campaign, endorsed Donald Trump for president, and declared he will campaign for him.

You should watch it, especially beginning from around seven minutes into the speech, when he begins to describe at length the tyrannical anti-democratic nature of today’s modern Democratic Party, and why that nature has forced him to leave that party, the party of his father, Robert Kennedy and his uncle, John Kennedy, to which he has belonged since he was a child. The key quote:

I attended my first Democratic convention at the age of six in 1960 and back then, the Democrats were the champions of the Constitution of civil rights. The Democrats stood against authoritarianism against censorship against colonialism, imperialism and unjust wars. We were the party of Labor of the working class. The Democrats were the party of government transparency and the champion of the environment. Our party was the bulwark against big money interests and corporate power. True to its name. It was the Party of Democracy.

As you know, I left that party in October because it had departed so dramatically from the core values that I grew up with. It had become the party of war censorship, corruption, big Pharma, big tech big ag and big money wanted abandoned democracy by canceling the primary to conceal the cognitive decline of the sitting president.

He now sees Trump as the only way now to prevent this party of censorship and corruption from destroying our great nation.

This quote however does not give you the full flavor of his speech. It is nuanced, thoughtful, educated, and principled. You might not agree with everything he believes, but you will discover that he came to those beliefs based on rational thought, reasoned research, and critical thought. And it is that ability to think critically and openly about the Democratic Party — that he and his family have been an integral part for more than half a century — and to reject it and endorse Donald Trump. It is therefore incumbent upon every American citizen to do the same, to use our brains to make a thoughtful (not emotional) choice in November.

Which means it is incumbant upon everyone to spend a short 40 minutes to watch this speech. If you run it at 1.5 speed you can still understand everything, it will take less time.

Finding beauty on Mars in all the strange places

Overview map

Beauty on Mars
Click for original image.

Cool image time! The picture to the right, cropped to post here, was taken on May 23, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).

The white dot in the inset of the overview map above indicates the location on Mars, smack dab in the middle of the 2,000-mile-long mid-latitude strip that I call glacier country, because practically every close-up image of this region shows glacial features.

This picture is no exception. The arrows in the inset show the downhill grade, falling about 1,700 feet across the entire inset. That grade is a reflection of the transition that takes place in this glacier country from the cratered southern highlands to the northern lowland plains.

I decided to crop the image at full resolution — showing only a tiny portion — because to my eye these curving linear grooves, produced naturally as Mars’ climate cycles cause glaciers to shrink and then grow repeatedly so that each cycle lays down a new line while squeezing the previous lines, are almost like a work of art. This might be nothing more than a glacier on an alien planet, but nature has caused it to form a very beautiful picture.

NASA adds three orbital tug startups to its contract bid list

9:55 am

NASA yesterday added three orbital tug startups to its contract bid list, allowing these companies to bid on projects that require the deployment of NASA smallsats to different orbits after launch.

NASA announced Aug. 22 that it selected Arrow Science and Technology, Impulse Space and Momentus Space for its Venture-Class Acquisition of Dedicated and Rideshare (VADR) contract. That selection allows them to compete for task orders for launching specific missions, typically small satellites willing to accept higher levels of risk in exchange for lower launch costs.

Arrow provides small satellite companies the deployment equipment used to release the satellite after launch. Impulse and Momentus have orbital tugs that not only deploy smallsats, but move them to their preferred orbit after the tug’s release from its launch rocket.

This NASA announcement allows its smallsats to be launched on either a dedicated small rocket that puts the satellite in its desired orbit or as part of a larger rideshare launch with many satellites that then uses the tug to get the satellite where it needs to be.

Amazon commits almost $20 million more to expanding its satellite production facility

9:46 am

Amazon yesterday revealed it is going to spend an addition $19.5 million to expand its satellite production facility at the Kennedy Space Center in Florida in order to overcome the long multi-year delay in getting production started.

The company said Aug. 22 the investment will support a secondary, 3,900-square-meter support facility at the site, which would help accelerate launch cadence amid a looming regulatory deadline to deploy half the constellation by July 2026. The building would join a 9,300-square-meter satellite processing facility Amazon announced last year at Kennedy’s runway-equipped Launch and Landing Facility, bringing total investment in the site to nearly $140 million.

The company hopes to open this additional facility by next year. It will need it, because its FCC license for its Kuiper internet constellation — conceived to be similar to SpaceX’s Starlink — requires it to launch half of the constellation of 3,200+ satellites by 2026 and have the entire constellation in orbit by 2029. Meeting that first deadline will be challenging at this point, though the company hopes to be launching frequently in the next few years. It has contracts to launch satellites 46 times on ULA rockets (8 on Atlas-5 and 36 on Vulcan), 27 times on Blue Origin’s New Glenn, 18 times on ArianeGroup’s Ariane-6, and 3 times on SpaceX’s Falcon-9. To provide payloads for those launches however it will need to be able to quickly build a lot of satellites, and that’s what this additional investment is for.

It must be noted again that the Kuiper constellation was first proposed by Amazon at almost the exact same time as Elon Musk proposed his Starlink constellation. SpaceX now has several thousand satellites in orbit and is earning several billion dollars per year from several million signed up customers. Amazon in comparison has only launched two test satellites and zero operational satellites in that same time frame.

Norway approves spaceport license for Andoya

9:31 am

Proposed spaceports surrounding Norwegian Sea
Proposed spaceports surrounding Norwegian Sea

The Norwegian government announced yesterday that the Andoya spaceport that has been used for decades for suborbital test launches, has been given a spaceport license to conduct orbital launches from the site.

According to a statement from the Norwegian ministry, the license allows the spaceport to conduct up to 30 launches a year, including four during overnight hours. Those launches, to be overseen by the Civil Aviation Authority of Norway, can take place on azimuths between 280 and 360 degrees, supporting missions primarily to polar and sun-synchronous orbits.

The German rocket startup Isar Aerospace already has a 20-year lease to conduct orbital launches from Andoya, and hopes to do the first orbital test launch of its Spectrum rocket there. According to the Norway government, the first launch is planned for this year, but that likely will only be a suborbital test, not a full orbital launch. Of the three rocket startups from Germany, Isar is the only one that has not yet done any engine tests (as far as we know) or suborbital test launches of its rocket engine or design. Hyimpulse has done a suborbital test launch from an Australian spaceport, and Rocket Factory Augsburg have done numerous tests both in Germany and at the Saxaford spaceport. This license to Andoya will likely signal the start of those public tests by Isar.

A fourth European rocket startup, PLD from Spain, is presently prepping its own launchpad in French Guiana, and hopes to conduct its own first orbital test launch next year.

Until this week it appeared that Rocket Factory was in the lead to be the first European rocket startup to attempt an orbital launch. That changed when the rocket’s first stage was destroyed during a static fire launchpad engine test earlier this week. Right now it is not clear who is in the lead.

Rocket Factory identifies cause of failure during rocket static fire test

9:14 am

According to Rocket Factory Augsburg, its investigation into the explosion during the first full nine-engine static fire test of its RFA-1 rocket earlier this week has identified the cause of the failure.

In an update on LinkedIn on 22 August, RFA COO Dr. Stefan Brieschenk announced that the company had completed an initial internal review. In what Dr. Brieschenk describes as “very preliminary” findings, he explains that the company has identified an “oxygen fire in one of the turbopumps” as the root cause of the incident. “That engine and that turbopump have run before without issues, wrote Dr. Brieschenk. “Eight engines ignited. We had multiple back-up and safety systems in place that were supposed to shut everything down – but things did not align on Monday as planned.”

As he notes, this is very preliminary. The company probably still does not know why the fire occurred in that turbopump, and it will need to find out in order to fix the problem. And without that fix, it is almost certain the UK’s Civil Aviation Authority (CAA) will not issue the company a launch license when a new first stage is built and delivered to the Saxavord spaceport in the Shetland Islands where the launch is planned.

All in all, expect a delay of at least one year before that launch can occur. Base on the CAA’s past history, that delay could easily extend to two years.

Starliner decision expected tomorrow, August 24

9:04 am

According to a NASA update today, the agency will hold “an internal Agency Test Flight Readiness Review” to discuss whether to return Starliner manned or unmanned on Saturday morning, August 24, 2024 and then hold a press conference immediately afterward to discuss the results of that review.

What makes this review and press conference different from all previous Starliner reviews and conferences is that NASA administrator Bill Nelson will attend.

NASA Administrator Bill Nelson and leadership will hold an internal Agency Test Flight Readiness Review on Saturday, Aug. 24, for NASA’s Boeing Crew Flight Test. About an hour later, NASA will host a live news conference at 1 p.m. EDT from the agency’s Johnson Space Center in Houston.

The only reason a politico like Nelson would participate in such proceedings is because he has taken control of the decision-making process, and will make the decision himself. The review is likely to educate him as best as can be done in this short time, and he will then decide whether the two astronauts who launched on Starliner, Butch Wilmore and Suni Williams, will return on it in the next week or so, or will stay on board ISS until February 2025 and return on the next Dragon crew capsule scheduled to launch to ISS in late September.

Nelson might have decided to get involved on his own, but I am certain that if so it was strongly “encouraged” by officials above him in the White House. There is an election coming up, and the risks involved in using Starliner to return the astronauts must be weighed in connection not just with its engineering concerns but with its political ramifications also.

Nelson’s decision will also provide us a strong indication of a future Harris administration’s attitude toward space.

Today I saw a short clip of Donald Trump answering a question about whether he is getting the normal intelligence briefings traditionally given to all presidential candidates. His answer was startling:

Well I could [get them] if I wanted them, but I don’t want them. … They come in, they give you a briefing and then two days later they leak it and then they say you leaked it. The only way to solve that problem is not to take them.

On its face Trump is simply telling us he is now being careful with whom in the government he deals with. On a deeper level, he is showing us that he is no longer the naive businessman he was in 2016. At that time he wanted very much to reform Washington, but he thought he had the good will of the people in Washington to help him do it. (Remember, for most of his life he was a dedicated Democrat with many friends on the left.)

Instead, he found himself stymied and back-stabbed and attacked on all levels. » Read more

Chinese scientists find method to extract water from Chang’e-5 lunar samples

Proposed concept for extracting water from lunar regoilth
Proposed concept for extracting water from
lunar regoilth

Chinese scientists have found that by heating Chang’e-5 lunar samples to 1,700 degrees Fahrenheit it is possible to extract a significant amount of water. From the paper’s abstract:

FeO and Fe2O3 are lunar minerals containing Fe oxides. Hydrogen (H) retained in lunar minerals from the solar wind can be used to produce water. The results of this study reveal that 51–76 mg of H2O can be generated from 1 g of LR [lunar regolith] after melting at temperatures above 1200 K. This amount is ∼10,000 times the naturally occurring hydroxyl (OH) and H2O on the Moon. … Our findings suggest that the hydrogen retained in LR is a significant resource for obtaining H2O on the Moon, which are helpful for establishing scientific research station on the Moon.

A video in Chinese (hat tip BtB’s stringer Jay) that describes this research can be found here. (If any of my readers understands Chinese and can provide a translation of this video’s narration, I would be very grateful.) It includes an artist’s rendering (screen capture to the right) showing how such a system on the Moon could work to extract water from the soil. Sunlight would be focused by a lensed mirror into a glass-domed container, heating the ground. The water would evaporate, condense on the glass and be sucked into a tube that would transfer it to a water tank.

This design is of course very simple and preliminary. According to Jay, “They need to heat the soil to 1000℃ (1832°F) to get the iron oxide in the lunar soil to split, the oxygen combines with hydrogen to make water and iron (melting point of iron is about 1500℃). You will need a nuclear reactor to produce that much power for an inductive furnace to get that hot. Doing the calculation, it would take about 245kw to heat up a metric ton of dirt in one hour to a 1000℃ degrees. It could be done slower over 24 hours at 10kw.”

Despite the technical difficulties getting such equipment operational on the Moon, that this research suggests water can be produced practically anywhere on the lunar surface is signficant. It suggests that even if no easily accessible water ice is found in the permanently shadowed craters at the poles, lunar bases still have viable options for obtaining water, and they don’t have even be at the poles.

China launches communications satellite

11:33 am

China today successfully launched a new communications satellite, its Long March 7A rocket lifting off from its coastal Wenchang spaceport.

A short clip showing the launch can be found here. (Hat tip to BtB’s stringer Jay.)

The leaders in the 2024 launch race:

83 SpaceX
35 China
10 Rocket Lab
9 Russia

American private enterprise still leads the rest of the world combined in successful launches 98 to 53, while SpaceX by itself still leads the entire world combined, including American companies, 83 to 68.

New port for big cruise ships dropped in Florida because it threatens space operations

10:02 am

A plan to build a new terminal in Port Canaveral for the large cruise lines has now been dropped because the constant arrival and departure of those ships would hinder launches from both Cape Canaveral as well as the Kennedy spacport.

On Aug. 2, Florida Department of Commerce Secretary J. Alex Kelly and Florida Department of Transportation Secretary Jared Perdue expressed dismay about cruise-terminal plan changes that could affect the space industry. Kelly and Perdue, in a letter, said that unless the port returns to earlier plans for the berth, the Department of Transportation will shift investments to other seaports and spaceports, and the Department of Commerce will halt funding for Port Canaveral projects.

These threats were enough to cause the port to drop its plans.

This story strongly suggests that the Florida state government views the future income from spaceport operations to far exceed that of the tourist cruise business, and does not wish the latter to interfere with the former’s growth in any way.

Proposed commercial spaceport in Nova Scotia teams up with Voyager Space

9:54 am

The proposed commercial spaceport in Nova Scotia that was first proposed by the company Maritime Launch Services in 2017 has now signed a partnership deal with the space station company Voyager Space.

Voyager, through its Exploration Segment, will provide comprehensive engineering, design and fabrication support to Maritime Launch, leveraging more than six decades of combined aerospace and defense technology experience. Voyager will bring its decades of commercial spaceflight engineering, manufacturing, and operations capabilities to provide engineering design and development and buildup of select portions of the launch site on behalf of Maritime Launch. Voyager will work alongside Maritime Launch to analyze launch client requirements and integrate them into the current site layout.

Maritime’s original plan had been to provide a launch location and rocket (produced by a Ukrainian company). Satellite companies would sign with both for launch services. The invasion of the Ukraine by Russia in 2022 killed that arrangement. So did red tape, as the Canadian government only passed a law allowing spaceports to make deals with international partners at the start of August.

It appears Maritime has realized that without that rocket partner, it needs another experienced partner to help build the spaceport itself and make sure launches by many different rocket companies are done safely. It has now hired Voyager to do this, since that company is leading the Starlab space station consortium that includes many very experienced companies, including Lockheed Martin, Northrop Grumman, Airbus, Mitsubishi, and the European Space Agency.

First SLS/Orion manned mission faces new delays because of Orion heat shield issues

9:39 am

Orion's damage heat shield
Damage to Orion heat shield caused during re-entry in 2022,
including “cavities resulting from the loss of large chunks”

Because the damage to the heat shield on the Orion capsule that flew around the Moon in late 2022 remains somewhat unexplained, NASA is considering delaying the next SLS/Orion mission, presently planned for September 2025 and intended to be the first Artemis flight to carry humans and take them around the Moon.

The heat shield, already installed at the base of the Orion spacecraft, will take the brunt of the heating when the capsule blazes through Earth’s atmosphere at the end of the 10-day mission. On the Artemis I test flight in late 2022, NASA sent an Orion spacecraft to the Moon and back without a crew aboard. The only significant blemish on the test flight was a finding that charred chunks of the heat shield unexpectedly stripped away from the capsule during reentry as temperatures increased to nearly 5,000° Fahrenheit (2,760° Celsius).

The spacecraft safely splashed down, and if any astronauts had been aboard, they would have been fine. However, the inspections of the recovered spacecraft showed divots of heat shield material were missing.

Two years later, despite extensive investigation and analysis, it appears NASA has not yet identified the root cause of the damage. The ablative material used on Orion was similar (though not identical) to the material used successfully on numerous other heat shields since the 1960s, yet it did not perform as expected.

NASA is presently facing three options. Do nothing and fly the next mission as planned, with four astronauts. It could rethink the trajectory used during re-entry, though this would likely not change things significantly unless the astronauts don’t go around the Moon as planned. Or it could change the heat shield itself.

The first two options are very risky, considering the unknowns. The latter involves a major delay of at least two years.

A decision must be made soon however. To meet the agency’s schedule it must begin stacking SLS’s two solid-fueled strap-on boosters next month. Those boosters have a limited life expectancy originally estimated to be one year. In the first unmanned Artemis test flight in 2022, NASA because of other delays stretched that life span to two years, and had no problems with the launch. If it stacks the boosters now and then has to delay for two more years to redesign Orion’s heat shield, those boosters will have been stacked for three years when launched.

Considering how seriously NASA is taking the issues with Starliner, which are likely not as serious as a heat shield that doesn’t work reliably, it would seem insane for NASA to launch Orion manned without fixing its own problem. And yet, for more than two decades NASA has consistently not demanded the same safety standards for SLS that it has demanded for the private commercial rocket startups. We shall see if this pattern now persists.

I continue to believe that the first Artemis lunar landing will not take place before 2030 (at least six years behind schedule). This heat shield dilemma only strengthens that prediction.
