- Viasat decides not to replace ailing satellite
It apparently can make its expected customer load work with the satellite’s reduced capacity (by 90%) combined with capacity from its other satellites.
- NASA’s inspector general agrees SLS is too costly and it will be impossible to reduce that cost
The report is available here [pdf]. Normally I’d highlight each new IG report that notes these plain facts, but I’ve grown bored with doing so. They (as well as I) have been saying the same thing time after time — going back to 2011 — but nothing ever changes. We keep pouring money into an SLS rocket that costs too much, can’t launch frequently, and in the end won’t accomplish much of anything, while other space projects of greater value (for much less) go by the wayside.
And despite this report we shall continue to do so, because the federal government is broken utterly, from the White House down to the mail rooms in Congress and every agency in the executive branch. It has entirely abandoned its responsibilites to serve the American people. Instead its goal now is simply to funnel money to itself, even if that funnelling will bankrupt the country.

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
California creates segregated system that favors rescuing black children over whites
Segregation: The Democratic Party’s long held #1 goal,
then and now.
“Segregation today, segregation tomorrow, segregation forever!” In a clear tribute to its long history of racism and bigotry, the Democratic Party that now controls California’s government from top to bottom has created a segregated system for rescuing missing children that favors blacks over everyone else.
Gov. Gavin Newsom signed Senate Bill 673 into law on Sunday, making California the first state to create an alert notification system — similar to an Amber Alert — to address the crisis of missing Black children and young women.
The law, which will go into effect on Jan. 1, will allow the California Highway Patrol to activate the alert upon request from local law enforcement when a Black youth goes missing in the area. The Ebony Alert will utilize electronic highway signs and encourage use of radio, TV, social media and other systems to spread information about the missing persons’ alert. The Ebony Alert will be used for missing Black people aged 12 to 25.

Ancient flood lava on the upper slopes of the solar system’s largest volcano
Click for original image.
Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on July 13, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
In this one picture can be seen a glimpse of the entire history of the numerous lava eruptions that once dominated Mars when its giant volcanoes were active one to three billion years ago. The three aligned craterlike depressions likely signal the existence of a large lava tube below ground, placed there during an early large eruption, when the volcano was spewing out so much flood lava that such large tubes could form. The smaller meandering surface rills signal later eruptions that carried less flood lava and thus produced a smaller drainage features.
And finally, the rough and cracked appearance of the surface indicates the ancient age of those last eruptions, probably laid down about a billion years ago. Since then, the volcano has been dormant, and the frozen lava here has had time to erode, become roughened, and show signs of slowly wearing away.

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.
Engineers use lasers to create paving material from simulated lunar soil
Engineers in Europe have now successfully used lasers to melt the top surface of a simulated lunar regolith in order to turn that lunar soil into paving materials for roads and landing pads.
Though the experiement used a laser, that was only a surrogate for what would be done on the Moon, using sunlight focused by a magnifying lens.
Proceeding through trial and error, they devised a strategy using a 4.5 cm (1.8 inch) diameter laser beam to produce triangular, hollow-centred geometric shapes approximately 20 cm (8 inches) across. These could be interlocked to create solid surfaces across large areas of lunar soil which could serve as roads or landing pads.
Advenit adds: “It actually turned out to be easier to work with regolith with a larger spot size, because at millimetre scale heating produces molten balls that surface tension makes hard to aggregate together. The larger beam produces a stable layer of molten regolith that is easier to control. The resulting material is glasslike and brittle, but will mainly be subject to downward compression forces. Even if it breaks we can still go on using it, repairing it as necessary.”
The press release however noted almost as an aside what might be the most important result from this work: “The most practical response is to keep dust at bay by paving over areas of activity on the Moon, including roads and landing pads.” Lunar dust is very abrasive, is found everywhere, and is considered a fundamental and entirely unsolved problem for any future lunar base. This melting process, by sunlight, could conceivably eliminate the problem entirely at any base location by melting the surface dust.

SpaceX to offer Starlink for cell phones
SpaceX has now announced that its Starlink internet service will soon be available for cell phones that are already in use, allowing them access to service even in places where no cell towers exist.
Direct to Cell works with existing LTE phones wherever you can see the sky. No changes to hardware, firmware, or special apps are required, providing seamless access to text, voice, and data.
First Starlink will only provide text service in 2024, and then expand to voice and data in 2025.
This capability means that SpaceX will not only be in direct competition with AST SpaceMobile, which recently launched a satellite to test similar capabilities, it will be far ahead of it in that competition. In fact, SpaceX is setting Starlink up as the go-to company for all smartphones and home internet services. By 2025 you will not need any other provider to have phone and internet service globally.
No wonder private investment firms have been willing to invest almost $11 billion in the company. They see big profits on the horizon.
That our federal government dislikes this fact, and is doing everything it can to crush Elon Musk and the company, tells us much about government itself. It isn’t interested in promoting human success. Instead, its instinct is to squelch it.

NASA delays two ISS spacewalks as Russian engineers assess now stopped leak on Nauka module
NASA yesterday confirmed it is delaying by at least one week two ISS spacewalks in order to allow more time for Russian engineers to analyze the causes of the coolant leak on Nauka module and assess its short and long term consequences for the station.
The spacewalks were deferred from their original target dates to allow engineers additional time to complete their analysis of the coolant leak, which occurred on Oct. 9 and has now stopped. [emphasis mine]
The highlighted words are the most important takeaway. The leak has stopped leaking, though we have not been told why. The Russians might have closed off the leaking radiator from the system, or maybe the leak stopped on its own for unknown reasons. More information is clearly required.

First manned Starliner mission now delayed to April 2024
In a press release yesterday that outlined the updates to NASA’s scheduled manned missions to ISS, the agency confirmed that the first manned Starliner mission has now been delayed one more month, from March until April 2024.
The first crewed flight of the Starliner spacecraft, named NASA’s Boeing Crew Flight Test (CFT), is planned for no earlier than mid-April. CFT will send NASA astronauts and test pilots Butch Wilmore and Suni Williams on a demonstration flight to prove the end-to-end capabilities of the Starliner system. Starliner will launch atop a United Launch Alliance Atlas V rocket from Cape Canaveral Space Force Station in Florida, spend approximately eight days docked to the space station, and return to Earth with a parachute and airbag-assisted ground landing in the desert of the western United States. [emphasis mine]
The highlighted words underline the fact that this date is merely a target, and has been announced as part of the entire schedule for all the manned missions to ISS next year, fitting it in between two SpaceX crewed Dragon flights. It assumes Boeing will have the spacecraft ready by then, but based on that company’s track record, that assumption remains dangerous. Boeing has a lot of work to do, including parachute drop tests to fix the parachute cords as well as replacing the flammable electric tape installed throughout the capsule.

Falcon Heavy successfully launches Psyche asteroid mission
SpaceX’s Falcon Heavy rocket this morning successfully launched the Psyche mission to the metal asteroid Psyche, lifting off from Cape Canaveral.
The two side boosters successfully landed at their landing zones at the cape, each completing their fourth flight.
Psyche will now spend the next six years traveling to the asteroid Psyche, first flying by Mars in 2026 to gain some speed to get there. It will then go into orbit around the asteroid for almost two years.
The leaders in 2023 launch race:
72 SpaceX
45 China
13 Russia
7 Rocket Lab
7 India
American private enterprise now leads China in successfully launches 84 to 45, and the entire world combined 84 to 73. SpaceX by itself only trails the entire world combined (excluding American companies) 72 to 73.

Pushback: Naming the names of the leftist haters supporting Hamas in America
Nazi brown shirts destroying Jewish businesses on Kristallnacht
Bring a gun to a knife fight: Even though there really is little difference between the tactics used by Hamas in Israel now versus the tactics used by Antifa/BLM in the U.S. in 2020, the difference in the way the public is reacting is significant and must be noted.
The tactics themselves are straightforward. Set up a gang of thugs to commit violence and mayhem against anyone you disagree with. The Nazis used this approach with great success in its effort to demonize and destroy its enemies and the Jews in Germany. Antifa and BLM repeated that Nazi success in 2020, rioting, looting, and burning whole neighborhoods. The response from the public then was either downright fear and submissiveness, or an eager endorsement of these groups in the vague hope that saying nice things about them while sending them money might encourage them to go away.
In other words, just like in 1930s Germany, the general reaction was to kow-tow to these bullies, which only inspired them to commit more bullying. My blacklist column since 2020 illustrates that sad history.
With Hamas today however the response has been far far different. Not only is the public expressing outrage against Hamas’s brutality and genocidal behavior, it is also expressing anger and outrage against those who are trying to pander to it. The push back has been glorious to see.

Martian pseudo-frost terrain
Click for original image.
Cool image time! It is always dangerous to come to any quick conclusions about what you see from pictures from another planet. The photograph to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 19, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), and shows what at first glance looks like a surface similar to frosting seen on window panes on Earth in the winter, where water condensation freezes to form crystalline patterns.
Your first glance would be wrong. This terrain is about 120 miles north of the Martian equator, placing inside the dry equatorial regions where no near-surface ice is known to exist. If this geological feature is formed by the same condensation processes that create ice frost, then it must involve the deposition of some other type of material.
The explanation would also have to account for the change in the terrain, from finely patterned on the right to more crystalline on the left.

Space Force puts a halt to the use of AI because of security issues
The Space Force has decided to stop using any artificial intelligence computer tools (AI) because of the security risks that presently risk in using them.
The Sept. 29 memorandum, addressed to the Guardian Workforce, the term for Space Force members, pauses the use of any government data on web-based generative AI tools, which can create text, images or other media from simple prompts. The memo says they “are not authorized” for use on government systems unless specifically approved.
Chatbots and tools like OpenAI’s ChatGPT have exploded in popularity. They make use of language models that are trained on vast amounts of data to predict and generate new text. Such LLMs have given birth to an entire generation of AI tools that can, for example, search through troves of documents, pull out key details and present them as coherent reports in a variety of linguistic styles.
Generative AI “will undoubtedly revolutionize our workforce and enhance Guardian’s ability to operate at speed,” Lisa Costa, Space Force’s chief technology and innovation officer, said in the memo. But Costa also cited concerns over cybersecurity, data handling and procurement requirements, saying that the adoption of AI and LLMs needs to be “responsible.”
This decision appears very wise. The insane fad in the last year to quickly adopt and even rely on AI has more than baffled me. Why are we in a such rush to let a robot do our for thinking and creative work for us? Have we become so lazy and dependent on computers that we’d rather let them do everything?
It is always dangerous to jump on a fad, without thought. That the Space Force has realized this is excellent news.

Long delayed and overbudget NASA satellite refueling mission expects more delays and further budget overruns
According to a new inspector general report, a long delayed and significantly overbudget NASA satellite refueling mission, dubbed OSAM-1 and first proposed around 2010, will experience more delays and further budget overruns in order to get it off the ground by 2026, at the earliest.
A NASA plan to robotically repair and refuel satellites in orbit is way behind schedule and well over budget, says NASA’s Office of the Inspector General (OIG), with most of the blame falling on space tech contractor Maxar.
Maxar, one of the largest private businesses working on NASA’s On-Orbit Servicing, Assembly, and Manufacturing mission (OSAM-1), has been involved in the project since 2016, when the space agency’s idea was smaller in scope and known as Restore-L. According to the OIG, Maxar is two years behind schedule on delivering the the project’s spacecraft bus and its Space Infrastructure Dexterous Robot (SPIDER) robotic arm, and it’s unlikely OSAM-1 will come in under its $2.05 billion budget nor meet the December 2026 launch date NASA committed to in 2022. The bus is the main craft framework, and its attached SPIDER will hopefully repair and refuel satellites in orbit, once it all gets off the ground and works.
NASA isn’t without blame for the delays, the OIG said, but Goddard Space Flight Center’s (the NASA facility where the project is being managed) “struggle with development of several key components of the servicing payload” wasn’t the main issue. “We found that project cost increases and schedule delays were primarily due to the poor performance of Maxar … and its inability to provide the spacecraft bus and SPIDER in accordance with contract requirements,” inspectors concluded in their report.
The plan has always been to refuel the Landsat-7 spacecraft in order to demonstrate robotic in-space servicing of satellites. When first proposed, the idea was untested, and the project was intended to get this industry off the ground. Since then however Northrop Grumman’s MEV servicing robot satellite has leap-frogged NASA to twice reactivate two geosynchronous satellites. At the same time, at least a half dozen other private startups have now done robotic rendezvous and docking demos in orbit, and have actual contracts for their own servicing missions.
Moreover, all the private missions have concepts that are far simplier and cheaper than NASA’s. Rather pump fuel into the defunct satellite’s tanks, the MEV simply docks with the satellite using its now useless main engine nozzle, and once attached becomes a service module with its own fuel and engines to orient and move the satellite. The other servicing startups are doing similar things. No need to develop complex robot arms and fueling systems.
In other words, private industry can learn little from this NASA’s mission. By the time it launches the industry will likely be able to run rings around it. It has become a waste of money that should be shut down, now.

Moreover, all the private missions have concepts that are far simplier and cheaper than NASA’s. Rather pump fuel into the defunct satellite’s tanks, the MEV simply docks with the satellite using its now useless main engine nozzle, and once attached becomes a service module with its own fuel and engines to orient and move the satellite. The other servicing startups are doing similar things. No need to develop complex robot arms and fueling systems.
In other words, private industry can learn little from this NASA’s mission. By the time it launches the industry will likely be able to run rings around it. It has become a waste of money that should be shut down, now.
India schedules Gaganyaan launch abort test for October 21st
India’s space agency ISRO has now scheduled the first unmanned launch abort test of its Gaganyaan manned capsule for October 21, 2023.
The test Crew Module (CM), according to the statement, will be akin to the pressurized module that’ll hold crew members during their ascent to space — this version, however, will be unpressurized. It will be launched via a single-stage liquid rocket specifically developed for this mission that will simulate an abort scenario; the true CM, by contrast, will ride atop a 143-foot-tall (43.5-meter) Launch Vehicle Mark-3 (LVM3) rocket with a solid stage, liquid stage and cryogenic stage. The latter recently received human safety certifications, R. Hutton, project director of the Gaganyaan mission, said during a conference last month.
At present ISRO is targeting 2024 for the first manned mission, but that target date remains very uncertain.

Launch of Psyche asteroid mission delayed by weather
NASA and SpaceX today scrubbed the launch of the Psyche asteroid mission because of poor weather, rescheduling the Falcon Heavy launch to tomorrow, October 13, 2023 at 10:19 am (Eastern).
“For our first backup window, Friday morning, 50% chance for go conditions, with our concerns still being associated with storms in the area, where we have anvil clouds, some thick clouds, which are layered clouds, as well as cumulus clouds we get associated with storms,” Moses explained during the briefing.
“Looking at Saturday morning, a third backup window, there is still about the same probability, about 50% chance of go, and fairly similar conditions here, where there may be some storms around, but we expect most of any storms to be after our morning launch window,” she added.
The launch window for the mission closes on October 25, after which a major mission rescheduling will be required to get the probe to the asteroid Psyche, likely causing a year delay.

- Relativity signs multi-launch agreement with Intelsat
The launches are for Relativity’s new Terran-R rocket, not yet launched, and will begin as early as 2026. The deal likely also allows Intelsat complete freedom to go elsewhere if Relativity has problems delivering.
- Blue Origin confirms that Brent Sherwood, head of the company’s Advanced Development Programs, is retiring
This is likely part of the house-cleaning in connection with the exit of CEO Bob Smith. The company desperately needs new leadership willing to get something, anything, done.
- Astra considering selling 51% of its propulsion division as well as parts of other divisions
If so the company would be selling its most productive division at this point, suggesting its future is dim indeed.
- A picture of the outside of OSIRIS-REx’s sample collector
The rocks and dirt in the middle right are extra material from Bennu that were captured and retained outside the collector. The scientists say a preliminary look at the material has found carbon and water (held in molecules of other material), but that is not news, as we already knew both were there.
- Spacewalk on ISS cancelled as engineers assess the coolant leak from Russia’s Nauka module
This leak is far more serious than the previous two leaks, as it is part of ISS itself, not a Progress or Soyuz capsule that is there only temporarily.
- Sierra Space selected by DARPA for its “10-year lunar architecture study”
The tweet suggests merely that Sierra has been selected to enter contract negotiations, not that it has won a contract.

You can’t negotiate with someone who wants to kill you
The horrors that occurred in Israel this past weekend when Hamas terrorists committed an organized attack on innocent civilians living near the Gaza Strip should finally put an end to demands that Israel negotiate with these people. Such negotiations are as pointless as the endless negotiations seen in the 1930s with Hitler. All you will do each time is to give up ground that is then used by these villians to continue waging war against you.
I say this with utter confidence for two reasons:
1. For decades the founding documents of both the Palestinian Authority (in control of the West Bank) and Hamas (in control of Gaza Strip) have made it very clear that they do not recognize the existence of Israel, and that their eventual goal is its utter destruction, including the elimination of all its citizens. Hamas this weekend demonstrated how these thugs intend to achieve that elimination, by killing every Israeli Jew they can find.
2. Repeatedly Israel has demonstrated forcefully its willingness to live in peace with the Palestinians, and each time has been met with hate and murder. In Gaza specifically Israel unilaterially exited in 2005, actually forcing Israelis who had settled there to give up their property so that Gaza could be handed in its entirety to the Palestinians as their own independent nation. At that moment the Palestinians had an opportunity to prove they wanted to live in peace. Instead, they elected a terrorist organization to run Gaza, and have spent the last two decades using it as a base for attacking and killing Israelis.
The attack this past weekend simply underlined these two fundamental facts. » Read more
Massive landslide in Martian canyon
Click for original image.
Cool image time! The picture to the right, cropped, reduced, enhanced, and annotated to post here, was taken on September 5, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
The image shows a gigantic landslide collapse on the southern interior wall of a long meandering canyon on Mars dubbed Bahram Vallis. The collapse was what scientists call a mass wasting event, in which the entire section of cliff wall breaks off and moves downward as a large unit. In this case the falling section, a half mile wide and long, got squeezed near the bottom, piling up rather than flowing out into the canyon floor.
At this particular location the canyon is 2.4 miles wide, with cliff walls about 1,700 feet high. Imagine when this piece broke off: In one instance a giant section of mountain about a half mile long fell about a thousand feet. Even in Mars’ thin atmosphere the sound must have been thunderous.

South Korea is in final negotiations to cancel two Russian launch contracts
As has been expected since the beginning of Russia’s invasion of the Ukraine, South Korea is in the process of canceling two Russian launch contracts, with the negotiations apparently now in the final stages.
“The Korea Multipurpose Satellite 6 and the next-generation mid-size satellite Compact Advanced Satellite 500-2, both developed by Korea, were initially scheduled to be launched into space using Russian launch vehicles, but due to the war between Russia and Ukraine and the subsequent international sanctions against Russia, there were uncontrollable circumstances that prevented the use of Russian launch vehicles,” the Ministry of Science and ICT said in a statement.
“Since then, Korea has been negotiating with Russia on the terms of termination of the satellite launch contract and it is currently being finalized.”
South Korea has already found a different rocket for the first satellite, scheduled for launch on Arianespace’s Vega-C rocket when it resumes flights in April 2024 (after completing upgrades resulting from a December 2022 launch failure). As for the second satellite, no public decision has yet been announced, though contract bidding has been on-going.
Meanwhile South Korea is accelerating development of its own Nuri rocket, which it has successfully launched two times already.
Russia in turn no longer has any international customers for its rockets. Its invasion of the Ukraine has cost it hundreds of millions of dollars of lost business, all of which will likely not return for decades.

Astrobotic resumes suborbital test flights of assets purchased from Masten bankruptcy
The startup lunar landing company Astrobotic has resumed flights and testing of the suborbital spacecraft built by the company Masten Space Systems and obtained when that company went bankrupt.
Astrobotic announced Oct. 10 that it completed the first campaign of test flights by Xodiac, a vertical-takeoff, vertical-landing vehicle, since acquiring it and other Masten Space Systems assets last year. Xodiac conducted four flights from Mojave, California, hovering just off the ground to test plume-surface interactions ahead of future lunar landing missions, supporting research by the University of Central Florida.
Xodiac was built several years ago by Masten Space Systems, based in Mojave, and made more than 150 low-altitude flights for a variety of technology demonstration investigations. However, the company filed for bankruptcy in July 2022 and its assets acquired by Astrobotic that September for $4.5 million.
Xodiac is now part of Astobotic’s Propulsion and Test Department, which includes other assets from Masten Space Systems as well as many of its former employees, who say they have picked up where they left off before the bankruptcy.
Astrobotic has also resumed development work on a larger Masten suborbital spacecraft, Xogdor, also designed to launch and land vertically, but actually reach space.
Because Astrobotic is mostly focused on developing lunar landers, Masten’s technology is perfect for refining that capability for landing on the Moon. It is also ideal should Astrobotic decide to develop a reusable rocket for launch from Earth.

- Sierra Space reiterates its commitment to Orbital Reef and its contracts with NASA
Based on the statement, which makes no mention of Blue Origin, this suggests that the rumors about a break-up between Sierra Space and Blue Origin on this project were really referring to Blue Origin getting kicked out, which will be especially embarrassing for Jeff Bezos as he and his company were the originators of the Orbital Reef space station concept.

Well deserved, though in this day and age one can’t help wondering how much of this award was given for political reasons beyond the team’s actual achievement.

Jay and I both noted this change by China in the October 4, 2023 quick space links, one week ago. Nor was this a surprise, as from the beginning I predicted Russia would not contribute much of anything to this partnership, and China began leaving Russia out of its presentations as early as September 2022.

This date suggests that the telescope is delayed, and will not launch next year as previously announced as recently as February 2023.

Broken Martian ice sheets?

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on August 11, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The picture was what the camera team call a “terrain sample,” which usually means the picture was taken not as part of any specific research request, but because there was a gap in the camera’s schedule, and in order to maintain the camera’s temperature the team then picks something to fill that gap.
Because of the relative randomness of such pictures, they sometimes show little of immediate interest. More often than not, however, the camera team chooses well, and snaps something cool.
In this case they achieved the latter. The white dot on the overview map above marks the location, inside the 2,000-mile-long northern mid-latitude strip I dub glacier country. Everything in this region seems covered with glacial and ice debris, and this picture is no different. Rather than a glacier however we have what looks like a broken ice sheet, surrounded by that utterly unique and as-yet unexplained Martian geological feature dubbed brain terrain.

October 12 Falcon Heavy launch of Psyche probe faces bad weather
At present there is only a 20% chance that the Falcon Heavy launch of NASA’s Psyche asteroid probe will occur on October 12, 2023 at 10:16 am (Eastern) as planned out of Cape Canaveral.
The launch window only extends until October 25, 2023, after which the entire project would have to be redesigned, requiring a significant delay.
SpaceX has become very adept at threading the needle when weather restricts its Starlink launch abilities, but it has less flexibility with Psyche. To increase its chances it has scrubbed a planned Starlink launch this week from Cape Canaveral in order to give the Falcon Heavy launch more launch opportunities.
Regardless, the live stream can be accessed here.

Aerojet Rocketdyne satellite power units are chronically failing
According to space insurers, problems on power units built by Aerojet Rocketdyne on four different satellites are going to cost the industry about $50 million in claims this year.
According to multiple insurance sources, Yahsat’s Al Yah 3, Avanti Communications’ Hylas 4, and Northrop Grumman’s two Mission Extension Vehicles (MEV-1 and MEV-2) are operating with reduced power to their thrusters following a problem with onboard Power Processing Units (PPUs).
The PPUs from Aerojet Rocketdyne provide the electrical power their thrusters need for station-keeping in geostationary orbit (GEO). One of the sources said Al Yah 3, Hylas 4, and MEV-2 have each lost one of two onboard PPUs since the issue emerged in 2022. The youngest of these spacecraft, MEV-2, launched in 2020.
While the article at the link focuses on the impact to space insurers for these additional claims, what I see are serious quality control problems at Aerojet Rocketdyne, now part of the company L3Harris after a summer acquisition. The new management of L3Harris better aggressively address this, or else it will find its $4.7 billion acquisition a big waste of money.

SpaceX blasts FAA for claiming falling satellites could by 2035 kill someone every two years
In a letter response to an FAA report to Congress issued last week, SpaceX has strongly criticized the FAA for claiming falling satellites from the many big constellations being launched now could by 2035 kill someone every two years.
The FAA’s report actually claimed that some of the risk of death from these satellites would come from space junk impacting airplanes. From the report:
“Some debris fragments would also be a hazard to people in aircraft. Projecting 2019 global air traffic to 2035 and assuming that a fragment that would injure or kill a person on the ground also would be capable of fatally damaging an aircraft, the probability of an aircraft downing accident (defined in the Aerospace report as a collision with an aircraft downing object) in 2035 would be 0.0007 per year.”
As SpaceX’s response correctly notes, this claim of a threat is absurd. Not only do the satellites from these constellations always burn up in the atmosphere — making the risk zero — the chances of a collusion that the FAA claims are still so infinitesimal they should not have been considered worth mentioning. SpaceX also noted that the FAA’s analysis was based on obsolete Iridium satellites from the 1990s that are no longer being launched, not the kind of satellites and the preventive actions modern satellite companies take in flying them.
It appears this report is just another example of the full court press of the administrative state against not just SpaceX but all of private enterprise. By exaggerating the risk of space debris, the FAA is trying to justify more regulation and restrictions in an effort to garner more power to itself at the expense of freedom.

Another Russian module develops leak on ISS
For the third time in less than a year, a Russian spacecraft at ISS has developed a coolant leak, this time in Russia’s newest module to ISS, Nauka.
The Nauka radiator actually has been in space for over a decade waiting for Nauka to arrive so whether there is any commonality to the failures is difficult to assess. Roscosmos acknowledged the leak, but said the module itself is working fine and there is no cause for concern.
The previous two leaks were on a Progress freighter, and later on a Soyuz capsule. Though Nauka was only launched to ISS in 2021, its development began in the 1990s and was originally scheduled for launch in the early 2000s. Because of the delays this radiator was launched to ISS ahead of the module, in 2012. It sits outside the module where it can release its excess heat into space.
The Russians say that the leak is in a backup coolant system, but according to a statement by Anatoli Zak quoted at the link, this statement is too vague. At the moment the location of the leak remains unknown.
