  • Want a NASA rocket engine once intended for SLS? GSA has seven for sale!

The engine is the J-2X, a supposed upgrade of the Saturn-5’s J-2 upper stage engines. GSA is selling the components for seven, the auctions to be found here, here, here, here, here, here, and here.

Its proposed rocket family will look very familiar to those familiar with SpaceX.

FAST is essentially a larger version of the now-shuttered Arecibo radio telescope in Puerto Rico. It is hard to say if it is being used to its full potential at this time, as China right now doesn’t have that many qualified radio astronomers. This is why for a long while it tried to get foreigners to run it, unsuccessfully. With time, however, this will change.

It also appears they plan to fly it past both Venus and some asteroids on its way to the outer solar system.

It is is Chinese, so it would be nice if one of my readers who can read Chinese provides some explanation.

How private enterprise is solving the vulnerability of satellites to military attack

1:10 pm

Link here. The essay provides a nice overview of the U.S. military’s present conundrum on protecting all American satellites in orbit, not just military ones, and what it is beginning to do to solve it, now that the Space Force exists.

The approach is following three paths, with only the last two having any hope of success. First, the Biden administration is trying diplomacy to convince space-faring nations to ban future anti-satellite tests. This approach has really little chance of success.

The other two avenues involve innovations from private enterprise, launching many small satellites as part of a large constellation and in-orbit servicing, repair, and refueling. The first creates redundancy, making it difficult for any enemy power to easily destroy U.S. assets. The second provides capabilities for both fixing important satellites as well as attacking our enemy’s without causing space junk. Both will become common in the coming years, and thus will become very viable tools for military use.

Today’s blacklisted American: Google, Paypal, Venmo team up to blacklist a gay organization

Paypal,Venmo, and Twitter

Blacklists are back and big tech likes ’em: Apparently because the homosexual advocacy group Gays Against Groomers opposes the exposure of queer ideology to little children, this week the big social media companies Google, Paypal, and Venmo did a coordinated crack down on the group, shuttering its accounts all within one day’s time.

Google, Paypal and Venmo shut down accounts affiliated with Gays Against Groomers, a Twitter account that is critical of gender ideology, particularly in regard to children. Venmo shut down the account early Tuesday morning, and Paypal blocked the account from its services minutes later, according to an email shared by the account’s founder Jamie Michell; Google shut down her account, including her email address, the following morning, according to a screenshot and an email.

Google reinstated the account the next day, but provided no credible explanation for its actions, at all.

In July this same organization had also been suspended by Twitter. The account was only reinstated when the group agreed to replace the letter “o” in “Groomers” with graphic eyeballs. It appears Twitter did not like the use of the word “groomers”, since it described precisely what queer advocates are doing when they espouse their perverse sexual behavior to young children.

The organization had been using its Twitter account to publicize examples where queer advocates performed sexually in front of kids. As it notes on its webpage:

Musk: Starship orbital attempt by November, at the latest

10:06 am

According to a tweet yesterday by Elon Musk, SpaceX engineers will likely have the first orbital prototypes of Starship and Superheavy ready for the orbital attempt either late in October, or by November. His full tweet:

Late next month maybe, but November seems highly likely. We will have two boosters & ships ready for orbital flight by then, with full stack production at roughly one every two months. [emphasis mine]

The highlighted words are the most significant. SpaceX is not building one rocket for test, like NASA has done with SLS. It is building an assembly line of test rockets, so that it can do a fast series of test launches plus upgrades, leading to quick and reliable operations. Should any one rocket launch fail, the company will speedily move on to the next, with little or no delay.

Should SLS fail in its first test launch sometime in the next month, NASA has no back-up. The entire program will be shattered, with no easy way to recover.

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.

Roscosmos head: Russia likely to remain ISS partner through 2028

9:57 am

According to a statement made by Yuri Borisov, the head of Roscosmos, during a press conference today, Russia now will definitely remain an ISS partner through 2024, and likely through 2028, assuming the station remains safe and operable.

These statements fit well with the “kinder, gentler” approach that Borisov seems to be taking in his relations with Russia’s international partners in space, compared to the bellicose and often hostile attitude of Roscosmos’s previous boss, Dmitry Rogozin. Borisov has been trying to ease the tension. He quickly signed the barter agreement with NASA allowing for crew exchanges on each other’s spacecraft, and has made it clear almost immediately that the ISS partnership was solid.

I strongly suspect Borisov will eventually offer OneWeb the return of its 36 satellites that Rogozin confiscated. This is not likely to regain Russia OneWeb’s commercial business, but it would do a lot to make it less a pariah in the international launch market.

Nova Scotia spaceport signs deal with British rocket startup

9:46 am

Capitalism in space: Maritime Launch Services, the company that is building a spaceport in Nova Scotia, has signed an agreement with the British rocket startup Skyrora, naming its Skyrora-XL rocket as one of the launch providers for that spaceport.

As part of the agreement, Maritime Launch will purchase the vehicles and vehicle support staff from Skyrora for their satellite clients. Spaceport Nova Scotia will provide Skyrora a launch pad, ground and operations support, public safety services, regulatory approvals and mission integration facilities and staff. Skyrora will supply the launch vehicle, mobile launch complex, and launch operations support team to Maritime Launch.

Unlike other new spaceports, Maritime is running Spaceport Nova Scotia a bit differently. Most new spaceports simply provide a launch site for rocket companies. Maritime instead wants to offer satellite companies a full service spaceport, including the rocket. Initially the plan was to use a Ukrainian-built rocket, Cyclone-4M, as part of the service, but the Russian invasion of the Ukraine has made its availability uncertain.

This deal gives Maritime a new option to offer satellite companies. However, the Cyclone-4M was already somewhat tested, as it was an upgrade of the Ukrainian Tsiklon-4 rocket, which has already launched. Skyrora is only a startup, and has not yet flown.

SLS fueling test completed

9:38 pm

NASA engineers today successfully completed the tanking test of the agency’s SLS rocket, completing all objectives after successfully dealing with a hydrogen fuel leak at the beginning of fueling.

The four main objectives for the demonstration included assessing the repair to address the hydrogen leak identified on the previous launch attempt, loading propellants into the rocket’s tanks using new procedures, conducting the kick-start bleed, and performing a pre-pressurization test. The new cryogenic loading procedures and ground automation were designed to transition temperature and pressures slowly during tanking to reduce the likelihood of leaks that could be caused by rapid changes in temperature or pressure. After encountering the leak early in the operation, teams further reduced loading pressures to troubleshoot the issue and proceed with the demonstration test. The pre-pressurization test enabled engineers to calibrate the settings used for conditioning the engines during the terminal count and validate timelines before launch day to reduce schedule risk during the countdown on launch day.

Teams will evaluate the data from the test, along with weather and other factors, before confirming readiness to proceed into the next launch opportunity. The rocket remains in a safe configuration as teams assess next steps. [emphasis mine]

The highlighted words are key. NASA has proposed a September 27, 2022 launch date. For that launch to occur, the rocket must remain on the launchpad, where it is impossible to check the batteries for operating the flight termination system used by the military range office to destroy the rocket should it go wildly out of control during launch. To check the batteries they need to roll it back to the assembly building, and one week is simply not enough time.

The vagueness of the highlighted language suggests that NASA has not yet gotten a waiver from the range for that date. Nor should it. Those batteries normally have a 20-day limit. On September 27th they will been unchecked for about 42 days, well past their use-by date.

This will be the first test launch of this rocket. Such first launches very frequently go wrong, and if SLS goes wrong, it would go wrong in a very big way, considering the size of the rocket. To do such a risky launch with a questionable flight termination system would not simply be improper it would be downright criminal.

The powerpoint presentation can be viewed here [pdf]. Lots of interesting details, including the revelation that Rocket Lab is considering the construction of its own manned capsule.

To make sure there is no confusion, the satellite did not break apart. Instead, it appears to have been made of two spacecraft that have now undocked from each other and are testing automatic rendezvous and docking procedures, similar to the tests that Astroscale was doing.

The project is targeting 2030 for launch. The picture of the “hopper” at the link looks more like a Boston Dynamics robot dog.

Based on the deal with the UAE on the lunar Chang’e-7 mission, China is looking for other countries to sign on, and will likely get a few.

The deal doesn’t appear to include anything specific, only for both to explore future cooperation, including flying Canadian astronauts on Axiom’s station. Also, this deal suggests Canada will get the contract to build the robot arm for Axiom.

The company had previously done a 20 second test fire, and is still hoping to launch by the end of the year.

Martian layers everywhere!

1:38 pm

Layers in Argyre Basin
Click for full image.

Cool image time! The photo to the left, rotated, cropped, and reduced to post here, was taken on June 1, 2022 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows the rim edge to a fifteen-mile-wide canyon, with many apparent layers exposed on the high plateau.

The layers are intriguing in that they suggest several things. First, they give us a glimpse into the top and youngest layers that make up the interior canyon wall. Second, they tell us that erosion has removed much of those top and youngest layers, resulting in the mesas on that plateau.

Finally, the gullies flowing down into the canyon indicate further erosion processes, eating away at the canyon wall over time.

The location of this canyon is also intriguing.

Pushback: NY cops fight city’s COVID jab mandate

NY Mayor Eric Adams: an enthusiastic tyrant
NY Mayor Eric Adams: an enthusiastic tyrant

Bring a gun to a knife fight: In the past week three stories from New York City suggest that the willingness to fight against the irrational and abusive COVID shot mandates imposed by the one-party rule of the Democratic Party in that city can win.

First, a state judge in New York on September 13, 2022 ruled in favor of a lawsuit by police officer Alexander Delito, stating that the city cannot fire him for refusing to get the jab. Delito had apparently been arbitrarily denied a religious exemption, with no explanation. As the judge noted in his decision:

“The hollow and generic phrase ‘does not meet criteria’ cannot be rational because not a single item particular to [Deletto] was discussed and not a single reason for the decision was given,” Justice Arlene Bluth ruled. “There is no indication that anybody even read [Deletto’s] arguments. It is the duty of the agency to explain why it made the decision,” the judge added.

The ruling sets a precedent that will make it difficult for New York City to continue the mandate. Not surprisingly, a week later the city’s Democrat mayor, Eric Adams, announced he is lifting the mandate on the private sector and on school children, even as he refused to remove it from government workers.

The response from the leaders of various government unions was immediate. Here is just one example:

Another model attempts to show how liquid water could have once existed on Mars

11:07 am

The uncertainty of science: Scientists today published a new model that attempts to show how it was possible in the distant past for liquid water to have existed on the surface of Mars.

New research published in Earth and Planetary Science Letters suggests that Mars was born wet, with a dense atmosphere allowing warm-to-hot oceans for millions of years. To reach this conclusion, researchers developed the first model of the evolution of the Martian atmosphere that links the high temperatures associated with Mars’s formation in a molten state through to the formation of the first oceans and atmosphere. This model shows that — as on the modern Earth — water vapor in the Martian atmosphere was concentrated in the lower atmosphere and that the upper atmosphere of Mars was “dry” because the water vapor would condense out as clouds at lower levels in the atmosphere. Molecular hydrogen (H2), by contrast, did not condense and was transported to the upper atmosphere of Mars, where it was lost to space. This conclusion – that water vapor condensed and was retained on early Mars whereas molecular hydrogen did not condense and escaped – allows the model to be linked directly to measurements made by spacecraft, specifically, the Mars Science Laboratory rover Curiosity.

As a model, this theory proves nothing, though it is very intriguing. The scientists propose that the heat from the planet’s interior replaces the known lack of energy that came from the Sun in Mars’ far past. While this could work, what makes it very uncertain is that its surface data is based on a single measurement from Curiosity, hardly a deep and convincing baseline.

Ingenuity completes 32nd flight

10:21 am

According to a tweet from JPL, Ingenuity successfully completed its 32nd flight on Mars on September 18, 2022.

The 55.3-second flight covered 93.74m at a max speed of 4.75 meters per second.

That is about 308 feet distance, comparable to the helicopter’s previous flight. Though it probably continued to the west, as with that last flight, JPL’s tweet did not provide any directional information.

This second short hop in a row however suggests that the team’s focus has definitely shifted from scouting for Perseverance to practicing precision landings, thus gathering data to help build the future Martian helicopter that will be used to pick up Perseverance’s core samples some time in the future.

Want to do a virtual hike in Jezero Crater on Mars? You can!

10:01 am

Using data from Mars orbiters, Perseverance, and Ingenuity, scientists have now created a virtual hiking map of Jezero Crater, allowing anyone to explore in detail the same places that the rover and helicopter have visited.

You can view the map here. From the press release:

The map allows virtual hikers to zoom in and out, and pan rapidly across scenes, so that they can explore the landscape from large scales down to centimetre-detail. Some of the 360° panoramas integrated with the waypoints have been synthetically rendered from orbital image data. Others are real panoramas stitched together from a multitude of single images taken by the Mastcam-Z camera instrument onboard the Mars 2020 Rover Perseverance, which have been provided by the University of Arizona. The sounds have been recorded by the SuperCam instrument on that same rover mission.

I’ve played with the map only a little, but find it quite amazing and useful, especially because it seems to work well on my relatively ordinary desktop Linux computer.

Launch startup Spinlaunch raises $71 million more in private investment capital

Spinlaunch prototype suborbital launcher
Spinlaunch’s prototype launcher

Capitalism in space: The radical launch startup company Spinlaunch announced yesterday that it has raised an additional $71 million in private investment capital, bringing the total it has raised to $150 million.

Unlike the many rocket startups, Spinlaunch proposes launching payloads using a centrifuge. The image to the right is of its prototype smaller scale launcher, which has already completed several test launches.

The company claims its full scale launcher will begin operations by 2026, but it has not yet revealed where it will be built, which means construction has not yet begun.

Such a launch system cannot be used by any satellite with delicate equipment. The g-forces during launch are too high. However, for getting bulk cargo, like water and fuel into orbit, such a system could become very profitable, if it can be made operational.

The science team for the James Webb Space Telescope today released that telescope’s first infrared image of Neptune.

That image is to the right, cropped and reduced slightly to post here. It is, as the press release touts, the best view in decades of Neptune’s rings. From the caption:

The most prominent features of Neptune’s atmosphere in this image are a series of bright patches in the planet’s southern hemisphere that represent high-altitude methane-ice clouds. More subtly, a thin line of brightness circling the planet’s equator could be a visual signature of global atmospheric circulation that powers Neptune’s winds and storms. Additionally, for the first time, Webb has teased out a continuous band of high-latitude clouds surrounding a previously-known vortex at Neptune’s southern pole.

The dots around the gas giant are the heat signatures of seven of its fourteen moons.

OneWeb announces delivery of 36 satellites to India for launch

Capitalism in space: OneWeb yesterday announced the delivery of 36 satellites to India for launch on that nation’s biggest rocket, the GSLV-Mark3.

Though no date for launch was mentioned, the press release did say this:

One additional launch will take place this year and three more are targeted for early next year to complete the constellation.

This suggests two launches before the end of the year, one by India with the second already contracted to SpaceX. As for the three launches next year, it is unclear yet who will launch them. OneWeb has contracts with SpaceX, Relativity, and NewSpace India Limited (NSIL), the commercial arm of India’s government space program which is doing this year’s GSLV launch. While Relativity has not yet launched, either SpaceX or NSIL could handle those launches for sure next year.

Hydrogen leak detected during today’s SLS tank test

9:08 am

Though engineers have apparently overcome the issue so that today’s tank test of NASA’s SLS rocket can continue, a hydrogen leak was nonetheless detected during fueling.

The fueling tank test is not yet complete.

At this moment I cannot imagine the military’s range office will allow NASA to launch on September 27th, as the agency has requested. To do so will require the range to ignore the possibility that the flight termination is inoperable, as its batteries are past their use-by date by almost a month. Combined with these ongoing leak issues, it would be irresponsible to do otherwise.

InSight’s power level holding steady

9:57 pm

InSight's on-going power levels

The Energizer bunny of Mars, the InSight lander, continues to hold on. The engineering team tonight issued another status report, as shown in the graph to the right. For the past week the lander continued to produce 420 watt-hours per day, even though the tau level of dust in the atmosphere increased from 0.8 to 0.85.

The tau level of dust outside of the winter dust season is normally between 0.6 and 0.7. Even though Mars is moving out of winter, that level has increased slightly above InSight. And yet, even with a higher dust content and thus less sunlight, the lander’s dust-covered solar panels are generating power, at a very slightly higher level.

The InSight team had expected the lander to die in early September, at the latest. Instead, it keeps running, thus allowing it to detect on September 5th an impact created by a cluster of three asteroids, the first time scientists have ever pinpointed exactly when such a new impact occurred on Mars.

For the lander to survive for even longer, all it needs is one gust of wind across the solar panels to clean them off. The science team had expected this to happen periodically, based on past experience with the Spirit and Opportunity rovers. Unfortunately for InSight, it has not yet happened even once since it arrived on Mars in 2018. Nonetheless, it only has to happen once to save the lander.

Stay tuned. All is not yet lost.

Jupiter’s endless interweaving storms

Jupiter's endless interweaving storms

Cool image time! The photo to the right, rotated so that north is up and then reduced slightly to post here, was created by citizen scientist Thomas Thomopoulos from a raw photo taken by Juno during its 44th orbit of Jupiter.

To bring out the details Thomopoulos enhanced the colors, then enlarged the entire photo and cropped the area of interest.

Unfortunately, the Juno team that releases these photos does not provide information for easily establishing scale. In an email to me Thomopoulos noted that the largest circular storm in the northern half of the image is likely a vortex, which on Jupiter tend to range from 600 to 3,500 miles in diameter. He also noted that Juno was a little less than 27,000 miles away from Jupiter when this photo was snapped on August 17, 2022. Thus, I suspect this particular vortex sits on the larger end of that size range, which makes it a little less than half the size of the Earth.

As for the colors, as with many similar Juno images, the white clouds appear to almost always sit at the top of these storms and jets, almost like thunderheads.

Though the largest feature here is that large vortex to the north, most of the gigantic Jupiter storms visible seem instead to form as bands, the storms churning about madly as they are driven along the gas giant’s very fast ten hour rotation period.

Today’s blacklisted American: Republicans and conservatives increasingly unwilling to talk to pollsters out of fear

12:45 pm

Joe Biden's
Joe Biden’s anti-conservative rally on September 1, 2022

Blacklists are back and the Democrats have got ’em: According to pollsters, the vicious almost slanderous attacks by President Biden against Republicans and conservatives — following decades of similar harsh language from Democrats nationwide — is causing these voters to increasingly refuse to talk to pollsters about their opinions.

In a Twitter thread, Trafalgar Group chief pollster Robert C. Cahaly said that President Joe Biden’s recent attacks on so-called “MAGA Republicans” will make polling supporters of former President Donald Trump even harder to poll than in previous years. Cahaly pointed out that in the last two presidential election cycles, name-calling and threats from prominent Democrats contributed to the phenomenon of the “shy Trump voter.” But as the 2022 midterms have begun in earnest, Biden’s escalating rhetoric against Trump supporters, accusing them of embracing “semi-fascism” and being a threat to America, will make these voters even harder to reach in polling.

NASA releases new overall objectives for exploration of solar system

11:28 am

NASA today released a new roadmap for its goal of exploring the Moon, Mars, and the rest of the solar system, with the goal of providing an overarching strategy for everything it hopes to accomplish.

The resulting revised 63 final objectives reflect a matured strategy for NASA and its partners to develop a blueprint for sustained human presence and exploration throughout the solar system. They cover four broad areas: science; transportation and habitation; lunar and Martian infrastructure; and operations. The agency also added a set of recurring tenets to address common themes across objectives.

You can read the full document here [pdf].

The most astonishing thing about this roadmap is its utter lack of any mention of race or gender, especially when one considers how obsessed the Biden administration and its minions in federal bureaucracy have been over such things. The goals are entirely focused on exactly what they should be focused on, exploration and research, with the goal of partnering with as many private and governmental entities as possible to get it done in the most efficient way.

The strange scattered rocks of Gediz Vallis on Mars

The strange rocks of Gediz Vallis
Click for full image.

Cool image time! The photo to the right, reduced to post here, was taken on August 20, 2022 by Curiosity’s high resolution camera. It shows some of the scattered and very delicate rocks that it is finding on the floor of Gediz Vallis, the valley the rover had been striving for since landing more than a decade ago and finally entered in mid-August.

Because of Mars weak gravity, about 39% of Earth’s, and very thin atmosphere, about 1% of Earth’s, it is possible for surface rocks to erode into such delicate shapes. The shapes appear to be further encouraged by the many layers that exist in Mars, with each layer having different characteristics. In the case of the hanging flakes to the right, these layers were more resistant to erosion and thus remains intact while material above and below was slowly blown away.

Researchers develop strongest-yet 3D printed titanium

10:21 am

Capitalism in space: Researchers at Monash University in Australia have successfully developed a 3D printed titanium alloy that has an internal strength exceeding that of normal commercially produced titanium.

In tests, the team demonstrated that the new titanium alloy had both elongation and tensile strengths (stretching and tension, respectively) of over 1,600 MPa. For reference, most commercial titanium alloys top out at around 1,000 MPa. This is also the highest specific strength for any other 3D-printed metal alloy, the team says.

Since 3D printing is going to be the main industrial manufacturing process in space, this process and the titanium it produces is certainly going to looked at with great interest by those who wish to build things in space. Imagine having a 3D printer that can make strong titanium parts in almost any needed shape. The possibilities are endless.

First meeting of all 21 nations who have signed Artemis Accords

10:13 am

For the first time yesterday, the 21 nations who have signed the Artemis Accords gathered together in a single meeting during the International Astronautical Congress being held in Paris this week.

The article at the link comes from the UAE’s state-run press.

Sarah Al Amiri, Minister of State for Public Education and Advanced Technology and chairwoman of the UAE Space Agency, attended the signatories’ meeting on behalf of the UAE. “During this meeting, heads of space agencies discussed future plans in the industry to ensure the safety of humans and deconfliction of activities on the Moon, as well as the importance of the Accords to emerging space nations,” she said.

Since the U.S. is the lead nation in these accords — with all signatories becoming participating partners in its Artemis program to settle the solar system — U.S. government policies will dominate any discussion. When the Trump administration established the Artemis Accords, a major goal was to establish property rights in space for private companies. Under Trump, the U.S. would have thus certainly exercised its power to make sure that was the goal.

With the Biden administration in charge, it appears the focus has shifted — for good intentions — to promoting international cooperation, which means the goals of our other international partners appear more dominant. Under Biden, the U.S. appears willing to allow these other countries to propose policy. Should this happen, I guarantee the opportunities for private enterprise as well as the freedom for future space generations will not be as promising.
