More Martian inverted rivers?
Click for original image.

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on June 23, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows what the scientists label “branching deposits,” two wiggling ridgelines with other ridges branching off from them.

What caused this? On Mars there are many such meandering ridges, all of which look like rivers that have positive relief, the opposite of what you would expect. The theory is that these weaving ridges were once canyons where either water or ice once flowed, compacting the streambed so that it was more dense than the surrounding terrain. When that terrain eroded away it left that streambed behind, as a raised meandering ridge.

That answer however might not apply here.

New Io images from Juno

9:43 am

Io as seen on October 15, 2023 by Juno
Click for original image.

The Jupiter orbiter Juno completed its 55th close pass of the gas giant on October 15, 2023, which also included a close pass of the Jupiter moon Io. The science team has now released the first images of Io from that fly-by, and several citizen scientists have released their processed versions.

The picture to the right, cropped, reduced, and sharpened to post here, was processed by Ted Stryk. It is the best view seen of this volcano-covered world since the Galileo orbiter in the 1990s. The dark patches are lava flows, with the dimensions of mountains along the terminator line between night and day clearly distinguishable.

An even closer look will occur during Juno’s 57th Jupiter orbit on December 30, 2023, when it will get within 1000 miles of Io’s surface, crossing the mid- to high latitudes of the planet’s western hemisphere.

Blue Origin announces another big project, with few details

9:17 am

Blue Origin has now announced another proposed big project, dubbed Blue Ring, which will put a platform into orbit as part of a new division focused on in-space services.

Blue Ring serves commercial and government customers and can support a variety of missions in medium Earth orbit out to the cislunar region and beyond. The platform provides end-to-end services that span hosting, transportation, refueling, data relay, and logistics, including an “in-space” cloud computing capability. Blue Ring can host payloads of more than 3,000 kg and provides unprecedented delta-V capabilities and mission flexibility.

The company did not reveal many details about the size of this orbital platform, nor did it reveal a time schedule. It appears to be an effort by the company to enter the orbital tug/satellite repair market, though the announcement is so vague it is hard to determine what exactly is being proposed.

The list of big ambitious Blue Origin projects is long and impressive: the New Glenn reusuable rocket, the Orbital Reef space station, the Blue Moon manned lunar lander, and now Blue Ring. However, since none of these projects has yet launched, and the first is years behind schedule, no one should put much money on this new project ever seeing fruition. Right now Blue Origin needs to actually fly something before anyone should take seriously any proposal it puts forth.

China to launch its second lunar relay communications satellite next year

9:01 am

China now plans to launch its second Queqiao lunar relay communications satellite early next year in order to support several upcoming missions, including Chang’e-6 mission to bring samples back from the far side of the Moon.

Queqiao-2 is set to launch on a Long March 8 rocket from the coastal Wenchang spaceport in early 2024, according to Zhang Lihua of DFH Satellite under the China Aerospace Science and Technology Corp. (CASC), the satellite’s developer. The 1,200-kilogram satellite will feature a 4.2-meter-diameter parabolic antenna and a mission lifetime of more than eight years, Zhang said during a presentation at the 74th International Astronautical Congress (IAC) in Baku, Oct. 3.

It will also be used later to provide relay communications to two additional Chang’e missions to the Moon’s south pole.

The satellite is an upgrade from the first Queqiao relay satellite, which is still operational but now at one of the Lagrange points rather than in orbit around the Moon. This new satellite is intended to be the first in a future constellation of lunar communications satellites, and is also being considered for the same use at Venus and Mars.

Once again it seems that China’s long term plan for the exploration of the solar system is not only rational and carefully thought out, it is also being implemented with increasing speed. Meanwhile in the U.S. our federal government seems schizophrenic, with one agency (NASA) trying to put together a long term plan using commercial space while other departments (FAA, FCC, Fish & Wildlife) doing everything they can to stymie this effort.

NASA to award small contracts to develop universal payload interfaces

8:49 am

NASA yesterday announced a competition to award up to three contracts to companies to develop a universal payload interface that can be used to more easily mount payloads prior to launch.

The NASA TechLeap Prize’s Universal Payload Interface Challenge invites applicants to propose an optimized “system of systems” to enable easy integration of diverse technology payloads onto various commercial suborbital vehicles, orbital platforms, and planetary landers. The proposed universal payload interfaces should seamlessly adapt a wide range of small space payloads – be they technologies, laboratory instruments, or scientific experiments – for flight testing.

A maximum of three winners will receive up to $650,000 each to build their system plus the opportunity to flight test it at no cost. The focus is on achieving a simplified and streamlined payload integration process that has the potential to accelerate future flight-testing timelines.

The idea is to have the same interface for mounting, either on flight testing on Earth (using high altitude balloons, aircraft, or suborbital spacecraft) or in space.

Applications are due by February 22, 2024.

ISS Russians to do spacewalk on October 25 to investigate Nauka coolant leak

8:38 am

Due to the coolant leak that appeared in a back up outside radiator connected to Russia’s Nauka module, NASA and Russia have rearranged their upcoming spacewalk schedule, with two American spacewalks now delayed until after a Russian spacewalk on October 25 that will investigate the leak.

During that spacewalk, [Oleg] Kononenko and [Nikolai] Chub will install a synthetic radar communications system on the Russian segment of the orbiting laboratory and deploy a nanosatellite to test solar sail technology. In addition, they plan to inspect and photograph the backup radiator that leaked on the Nauka multipurpose laboratory module.

The leak itself has stopped, though neither NASA nor Roscosmos have explained why. The leaked material is considered non-toxic, but there appears to be a concern it might get into some “internal systems” and cause problems.

NASA: Budget cuts to Hubble/Chandra under consideration

1:14 pm

In what is likely a negotiating ploy with Congress to prevent any budget cuts at all at NASA, the agency revealed late last week that it is considering cutting the budgets to both the Hubble and Chandra space telescopes in order to meet proposed budget limits.

In an Oct. 13 presentation to the National Academies’ Committee on Astronomy and Astrophysics, Mark Clampin, director of NASA’s astrophysics division, said he was studying unspecified cuts in the operating budgets of the Chandra X-Ray Observatory and Hubble Space Telescope to preserve funding for other priorities in the division.

The potential cuts, he said, are driven by the expectation that his division will not receive the full request of nearly $1.56 billion for fiscal year (FY) 2024 because of legislation passed in June that caps non-defense discretionary spending for 2024 at 2023 levels, with only a 1% increase for 2025. “We’re working with the expectation that FY24 budgets stay at the ’23 levels,” he said. “That means that we have decided to reduce the budget for missions in extended operations, and that is Chandra and Hubble.”

That he provided no details suggests this is merely a lobbying tactic. Essentially he is saying to Congress, “If you don’t give me more money I will be forced to shut down our most popular programs. That won’t sit well with your constituents!”

That the House in its appropriations to NASA for 2024 did not cut the agency’s budget significantly also suggests this is mere lobbying. There should be no reason to trim Hubble or Chandra, which are two of the agency’s most successful projects, unless the cost overruns on SLS/Orion and the Mars Sample Return missions are forcing NASA to grab money from other programs. If so, that problem is not Congress’s, but NASA’s. The agency should reconsider those failed projects in order to keep what works working.

The public wakes up, but the window for freedom will remain open for only so long

12:39 pm

Is a real house-cleaning about to happen?
Is a real house-cleaning about to happen?

The barbaric massacres committed by Hamas in Israel last week along with the left’s endorsement worldwide of those atrocities has appeared to awaken the long dormant outrage of the general population. Suddenly, people no longer seem willing to accept the lies and slanders of the left. Claiming Hamas was justified in killing babies and children while also taking many women and children hostage is a position that even many leftists cannot tolerate.

If you don’t believe me, watch this short clip from Bill Maher’s show, Real Time. Not only does Maher — a proud self-admitted lefty himself — trash the modern left in academia, the audience joins in to cheer that trashing.

It isn’t however only the left’s recent open support of Hamas that has inspired this disgust. It is also likely inspired by the many other abuses of power by the government (an arm of the power-hungry left) during the past three years. Those abuses, from lockdowns to censorship to blacklisting to mask and medical mandates, accomplished only one real thing: The abuses turned neutral ordinary people into ardent warriors against the left.

This shift was evident in three elections worldwide in the past few days.

Astronomers detect nano-sized quartz crystals in atmosphere of exoplanet

9:33 am

Using both the Hubble and Webb space telescopes in space, astronomers have detected nano-sized quartz crystals in the atmosphere of a Jupiter-class exoplanet orbiting its star every 3.7 days.

Silicates (minerals rich in silicon and oxygen) make up the bulk of Earth and the Moon as well as other rocky objects in our solar system, and are extremely common across the galaxy. But the silicate grains previously detected in the atmospheres of exoplanets and brown dwarfs appear to be made of magnesium-rich silicates like olivine and pyroxene, not quartz alone – which is pure SiO2.

The result from this team, which also includes researchers from NASA’s Ames Research Center and NASA’s Goddard Space Flight Center, puts a new spin on our understanding of how exoplanet clouds form and evolve. “We fully expected to see magnesium silicates,” said co-author Hannah Wakeford, also from the University of Bristol. “But what we’re seeing instead are likely the building blocks of those, the tiny ‘seed’ particles needed to form the larger silicate grains we detect in cooler exoplanets and brown dwarfs.”

These tiny quartz crystals are condensing out in the clouds themselves, due to the high temperatures and pressures there. The exoplanet itself is unusual because though its mass is one half that of Jupiter, its volume is seven times larger. This gives it a very large and deep atmosphere, thus providing the environment for crystal formation.

Update on Starship/Superheavy: Lots of work, no sign of FAA launch approval

9:20 am

Link here. The article provides a thorough review of the work SpaceX engineers have been doing in the past six weeks since the company announced on September 5th that it was ready to do a second test orbital launch of Starship (prototype #25) and Superheavy (prototype #9), but has been stymied by the refusal of the federal bureaucracy to grant a launch license.

For example, while waiting the company has done some tank tests with Starship prototype #26, which is not expected to fly but is being used for testing. The article outlines a lot of other details, but this is the key quote:

While Ship 26 started its engine testing campaign, SpaceX looks to be gearing up for a Wet Dress Rehearsal (WDR) for Booster 9 and Ship 25. Related notices have been posted for the coming week, marking the imminent return to a full stack for the next Starship to launch as soon as November, pending regulatory approval. [emphasis mine]

This source, NASASpaceflight.com, now admits that the FAA and Fish & Wildlife will not issue a launch license until November. Previous reports from it have tried to lay the blame for the delays on SpaceX. It now can no longer make that claim.

In April, after noting at great length the lack of harm done to wildlife by the first test launch (as admitted by Fish & Wildlife itself, the agency that is presently delaying things), I predicted the following:

[I]t appears that both the FAA and Fish and Wildlife are now teaming up to block any future launches at Boca Chica until SpaceX guarantees that the rocket and its launchpad will work perfectly. But since SpaceX must conduct launches to determine how to build and further refine the design of that rocket and launchpad, it can’t make that guarantee if it is banned from making launches.

We must therefore conclude that these federal agencies are more interested in exerting their power than doing their real job. They are therefore conspiring to shut Starship and Superheavy development entirely, or at a minimum, they are allowing their partisan hatred of Elon Musk and capitalism itself to delay this work as much as possible. As Lord Acton said in 1887, “Power corrupts, and absolute power corrupts absolutely.”

At that time I thought it very possible no further launches from Boca Chica would ever be approved. In May I refined that prediction, stating that come August the “…launch license will still not be approved, and we will still have no clear idea of when that approval will come. Nor should we be surprised if approval does not come before the end of this year.”

At the time that prediction was poo-pooed, with claims that I did not understand the regulatory process and that the government certainly did not want to stand in the way. It now appears my prediction was right on the money, and worse, my first prediction might be closer to the truth, that while the federal government doesn’t want to come right out and say, “No more launches from Boca Chica!”, it is imposing so many delays and requirements there that it makes the location impractical for SpaceX to use it as a launch test site.

The company desperately needs to get its second Starship/Superheavy launch site at Cape Canaveral operational. Otherwise it is unlikely it will ever be able to complete the development of this rocket.

China’s Long March 2D rocket launches military satellite

9:17 am

China yesterday used its Long March 2D rocket to place what is believed to be a military weather satellite into orbit, lifting off from its Jiuquan spaceport in the northwest of China.

Telecommunications company sues Commerce and Defense Departments $39 billion for theft

12:27 pm

The telecommunications company Ligado yesterday filed a $39 billion suit against the Commerce and Defense Departments for stealing use of the communications spectrum granted to it by the FCC for the establishment of a 5G cell phone network.

Ligado’s suit filed in the United States Court of Federal Claims [PDF] makes a number of allegations, including that the Pentagon has “taken Ligado’s spectrum for the agency’s own purposes, operating previously undisclosed systems that use or depend on Ligado’s spectrum without compensating Ligado.”

Those systems, a source close to the case said, are certain classified radars rather than GPS systems.

The suit cites a high-level DoD “whistleblower” who “revealed internal emails and discussions” that the company claims show DoD and Commerce “fabricated arguments, misled Congress in testimony supporting anti-Ligado legislation, and orchestrated a public smear campaign, which included repeating those false claims to the public and threatening Ligado’s business partners with canceling their own government contracts if they worked with Ligado.”

There had been some disagreement about whether Ligado’s use of this spectrem might interfere with GPS as well as other communications services. Nonetheless, the spectrum was legally Ligado’s. If the lawsuit is correct and these government agencies arbitrarilly took possession and used the spectrum illegally, thus preventing Ligado from establishing its business, it would appear to be another example of the arrogant administrative state ignoring the law to grab power.

Once I would have considered a suit like this to simply be a failed company’s effort to recover its losses by blaming the government. I no longer assume such things. Instead, my first thought is that the allegations are true, that bureaucrats in Defense and Commerce conspirated to steal the spectrum for their own uses, and didn’t care that they were violating the law.

The truth could be a combination of all these things, but if so that still tells us some very ugly things about the people who now work in these federal agencies.

  • 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.

California creates segregated system that favors rescuing black children over whites

1:20 pm

The Democratic Party's long held support of racial hate
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

12:40 pm

Ancient flood lava
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.

Engineers use lasers to create paving material from simulated lunar soil

9:22 am

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

9:06 am

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

8:54 am

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

8:45 am

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.

Pushback: Naming the names of the leftist haters supporting Hamas in America

1:39 pm

Nazi brown shirts destroying Jewish businesses on Kristallnacht
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

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

9:09 am

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

8:59 am

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.
