House rejects FCC bill because the bill approved FCC’s recent power grab

9:35 am

The full House yesterday failed to pass an FCC bill designed “to reform satellite spectrum licensing regulations” because of opposition to language that provided a backdoor approval of the FCC’s recent power grab that extended its regulatory power beyond its legal statutory authority.

[T]he leadership of House Science Committee opposed the bill because of provisions regarding regulation of space debris and space traffic management. They pointed to language in the bill that directed the FCC to establish “specific, measurable, and technology-neutral performance objectives for space safety and orbital debris.”

In a “Dear Colleague” letter circulated to House members ahead of the vote, the bipartisan leadership of the full committee and its space subcommittee argued that the FCC would be overstepping its authority by attempting to regulate space safety. “Congress has never explicitly granted FCC authority to regulate in these areas, and doing so now is a significant policy decision,” the letter stated, adding that the FCC also lacked expertise to do so. “Assigning FCC responsibility to both create these rules and assess an applicant’s compliance would divert resources from FCC’s primary mission of assessing the applicant’s spectrum use.”

While this sounds like Congress has actually decided to exercise its Constitution authority and restrict this maverick agency, don’t bet on it. The vote for procedural reasons required a two-thirds majority. 250 House members voted in favor, and 163 voted against, a clear majority in favor that was only 16 votes short of approval.

Moreover, even if Congress removes the language approving the FCC power grab and then passes the bill, it will have done nothing to stop that power grab. Expect FCC officials under Biden to ignore the law and continue to demand the right to regulate how satellites are de-orbited, something it hasn’t the knowledge or authority to do. Satellite companies will have to sue to stop it, an expensive task that will hinder their operations and cost money. Many will simply decide to go along.

The result will be a more powerful unelected administrative state — beholden to no law — and a weaker Congress unwilling to represent the American citizenry by wielding its Constitutional power.

World Economic Forum decides its business is running space too!

8:13 am

We’re the government and we’re here to help you! The World Economic Forum (WEF) yesterday released its proposed new set of guidelines for mitigating space junk in orbit, even though some of the most important commercial satellite operators (SpaceX and Viasat) have not signed on.

The Space Industry Debris Mitigation Recommendations document, released by the WEF June 13, outlines recommendations to avoid collisions that can create debris by limiting the lifetime of satellites in orbit after they have completed their missions and improving coordination among satellite operators.

Among those recommendations is to establish a success rate for “post-mission disposal,” or removal of satellites from orbit after the end of their missions, to 95% to 99%. That disposal should be completed no more than five years after the end of each satellite’s mission.

You can read the guidelines here [pdf], which the WEF is pushing governments worldwide to adopt. Though SpaceX and Viasat have not signed on, 27 companies have endorsed the guidelines, including OneWeb, Airbus, Axiom, and a host of orbital tug and space junk removal startups, the latter of which all benefit from these guidelines.

While the proposals makes some sense, everyone in the space industry should remain skeptical, and resist the call for more government regulation. Once this power is given to government it will never be recanted, and will only grow with time. Moreover, all signs indicate that such interference by law by government is unnecessary. Both satellite operators and most rocket companies (the exception mostly China) have been making strong efforts to deal with the issue of space junk, for profit. The fact that there are a host of orbital tug and space junk startups right now illustrates this. Investors have realized there is money to be made removing satellites and space junk. They don’t need government telling them what to do.

New House bill proposes giving FAA responsibility for monitoring space junk

10:10 am

A just proposed House bill for reauthorizing the Federal Aviation Administration (FAA) also proposes giving that agency the responsibility for monitoring space junk.

The bill instructs the FAA to establish a program to track objects “that are potential sources of covered airborne debris” with a focus on identifying those about to reenter and could pose a risk to aircraft in airspace. That program would coordinate with the FAA’s air traffic control system to identify airspace that needs to be closed for a reentry. It would allow the FAA to establish its own space situational awareness (SSA) facilities and work with other federal agencies, companies or international organizations for data on such objects.

While the focus of the bill is tracking debris to assess airspace risks, the bill does enable additional uses of the data the FAA collects. In particular, it directs the FAA to offer “a basic level of data, information, and services” at no charge. That includes maintaining a public catalog of space objects and “emergency conjunction notifications” of such objects.

The article at the link notes that this new FAA job would also duplicate work of the Space Force, as well as a new Commerce Department office tasked with similar responsibilities. It also duplicates the same responsibilities the FCC has created for itself, outside of its statutory authority.

In other words, there is a factional turf war going on within the swamp, with each faction attempting to establish its territory and control over this work.

The result? Expect Congress to allow this duplication to go forward, funding all three efforts. As we all know, money grows on trees, and hiring as many Washington bureaucrats is the most important thing Congress can do, even if those bureaucrats don’t do anything useful.

Space junk removal company ClearSpace signs deal to launch on Vega-C

9:59 am

The European company ClearSpace has signed a launch deal with Arianespace to fly the first test of its space junk removal robot on a Vega-C rocket set to launch some time in the second half of 2026.

The development of ClearSpace’s robot, which will use four grappling arms to surround and then capture its target, was paid for under a European Space Agency (ESA) $121 million contract which also required it to be launched on an Arianespace rocket. The problem right now is that it will fly as a secondary payload, and a primary payload has not yet been found.

Finding that primary payload is going to be difficult. First, Vega-C failed on its second launch last year and has not yet flown again. Second, it is expendable, and though cheaper than Arianespace’s other rocket, Ariane-6 (which has not yet launched), it is still more expensive than other commercial rockets now available. Third, the customer of that primary payload must also want to go into an orbit that will allow ClearSpace’s robot to reach its target, an abandoned Vega Payload Adapter from a previous launch.

As has been typical of Europe, this development is proceeding too slowly and is being hampered by requirements unrelated to profit and loss. By ’26 expect several other space junk removal companies — Astroscale and D-Orbit come to mind — to have already demonstrated their capabilities and already garnering market share, before ClearSpace even flies.

Startup proposes capturing space junk with a satellite operating like a whale

9:53 am

Paladin satellite capturing space junk

Paladin, a new space junk removal startup based in Australia, has now proposed building a satellite that would literally swallow space junk and then send it over the ocean to burn up.

The image to the right shows the satellite as a piece of junk is about to be captured. The advantage it has on all other designs for capturing space junk is its simplicity. No nets, no harpoons, no grappling arms. The debris is captured inside a box inside the satellite, and then that box is released to burn up. This quote from the startup’s founder and CEO, Harrison Box, illustrates well his investment argument:

“The European Space Agency is currently paying 100 million euros to remove just one item of space junk. That’s the value they put on the job,” says Box. “Imagine the value of being able to remove hundreds.”

Paladin is one of 29 startups that have divided up $14 million in development money provided by a program of the Australian government. Thus, it is only at the very beginning of development, without a lot of cash to work with.

The idea however is smart, with great potential.

Student cubesat demonstrates how to use a solar sail for satellite deorbit

10:04 am

Using cheap off-the-shelf parts students at Brown University have successfully tested a simple solar sail in space and shown how it can be used to de-orbit satellites efficiently and inexpensively.

They built a satellite on a shoestring budget and using off-the-shelf supplies available at most hardware stores. They even sent the satellite — which is powered by 48 Energizer AA batteries and a $20 microprocessor popular with robot hobbyists — into space about 10 months ago, hitching a ride on Elon Musk’s SpaceX rocket.

…The students added a 3D-printed drag sail made from Kapton polyimide film to the bread-loaf-sized cube satellite they built. Upon deployment at about 520 kilometers — well above the orbit of the International Space Station — the sail popped open like an umbrella and is helping to push the satellite back down to Earth sooner, according to initial data. In fact, the satellite is well below the other small devices that deployed with it. In early March, for instance, the satellite was at about 470 kilometers above the Earth while the other objects were still in orbit at about 500 kilometers or more.

Based on the data, it is expected the cubesat will burn up in the atmosphere in five years, not twenty-five or so predicted for the other cubesats launched to the same orbital elevation.

This experiment above all proves that most of the very expensive demo missions to test this kind of technology have been grossly over-budget. The entire cost of this student-built project was just $10,000, and it actually was more successful in proving this technology than a number of past solar sail projects that cost millions.

China’s Long March 4C rocket launches two Earth observation satellites

9:23 am

China today used its Long March 4C rocket to launch two Earth observation satellites from one of its interior spaceports.

No word on whether the expendable first stage landed near habitable areas. In related news the upper stage of a Long March 2D rocket, launched in June 2022, burned up over Texas on March 8, 2023. Such upper stage uncontrolled de-orbits are not unusual, and the effort by this news outlet to make a big deal about it is just politics. Unlike the lower stages of China’s rockets that hit the ground right after launch, it is very unlikely any pieces reached the surface, and any that did were small and posed a small risk.

The 2023 launch race:

16 SpaceX
8 China
3 Russia
1 Rocket Lab
1 Japan
1 India

American private enterprise still leads China 17 to 8 in the national rankings, and the entire world combined 17 to 13. SpaceX alone still leads the entire world, including American companies, 16 to 14.

ISS maneuvers to avoid satellite

9:02 am

Though a collision was unlikely, Russian engineers fired the engines of a docked Progress freighter on March 6, 2023 to adjust ISS’s orbits in order to guaranteethat an Earth-observation satellite would fly past harmlessly.

At approximately 7:42 a.m. (12:42 GMT), thrusters on the Progress 83 resupply vessel currently docked with the International Space Station (ISS) fired for a little more than six minutes, raising the station’s orbit to prevent the potential collision, NASA said in a blog post (opens in new tab).

The satellite in question appears to have been an Argentinian Earth-observation satellite launched in 2020, according to Sandra Jones, from NASA’s Johnson Space Center. In a tweet, Dr. Jonathan McDowell, astronomer and astrophysicist at the Harvard–Smithsonian Center for Astrophysics, narrowed the possible candidates down to Nusat-17, noting the constellation’s orbital decay.

The article at the link includes a nice graph showing the number of times per year engineers have had to do this since 1999. The number of such maneuvers ranges from 0 to 5 per year, with no clear trend up or down. That lack of a trend suggests the constant howls claiming that space junk is a growing problem might be a bit overstated. This is not to say it isn’t a problem, merely that the problem might not be as severe as some claim.

ISRO successfully de-orbits defunct satellite

9:09 am

Last orbit of MT1

ISRO announced today that it successfully de-orbited the defunct Earth observation MT1 satellite on March 7, 2023, bringing it down over the Pacific Ocean.

The map to the right shows the timing of the last two de-orbit burns during the satellite’s last orbit.

MT1’s orbit was high enough so that it would have remained in space for about 100 more years, with a lot of fuel that might have caused an explosion and the release of many pieces of space junk. ISRO managers decided to allocate the funds to use that fuel to de-orbit it, as a test for making this a routine part of any satellite end-of-mission.

ISRO attempting controlled reentry of old satellite originally lacking in such plans

9:54 am

India’s space agency ISRO has been attempting the controlled reentry of an old India-French climate satellite that had originally been placed in a high enough orbit that de-orbit was not expected.

An uninhabited area in the Pacific Ocean between 5°S to 14°S latitude and 119°W to 100°W longitude has been identified as the targeted re-entry zone for the [Megha-Tropiques-1 (MT1)]. Since Aug 2022, 18 orbit manoeuvres have been performed to progressively lower the orbit and on March 7 the ground impact is expected to take place between 4.30 p.m. and 7.30 p.m. IST.

The satellite, once no longer able to do its primary function, still had a lot of fuel left that left it a threat. ISRO managers decided to use that fuel to lower the high orbit — where MT1 was expected to remain for at least 100 years — so that the satellite could be brought down safely now.

The real story here is ISRO’s decision to commit funds to pay for this work. Until recently, most satellites are launched without any funding to remove them once launched. SpaceX changed this with its Starlink constellation, with deorbit always included as part of each satellite’s operational plan.

ESA successfully unfurls solar sail from cubesat

9:32 am

The European Space Agency (ESA) has successfully unfurled a solar sail from a cubesat in order to test using that sail to help de-orbit that cubesat more quickly.

The sail was deployed from a package measuring 3.93 by 3.93 by 3.93 inches (10 by 10 by 10 centimeters). The unfurling process was captured by an integrated camera onboard the Ion satellite carrier, which is operated by the Italian company D-Orbit.

The satellite will eventually burn up in the atmosphere, providing a quicker, residue-free method of disposal, according to ESA.

A short video of that unfurling can be viewed here.

This flight was intended as a proof of concept. Thus, ESA like many similar NASA test projects will now close the project down, which is dubbed ADEO, having no specific plans to do anything with what was learned. Private cubesat companies, however, might adopt this solar sail deployment technology, but I suspect less for de-orbit purposes but instead as a method of maneuvering their satellite in orbit.

Newly passed Senate bill requires consultation between industry and government on space junk

9:50 am

Though the bill still needs to be passed by the House, a just passed Senate bill requires consultation between industry and government on space junk, short circuiting recent attempts at the FCC as well as in the House to impose arbitrary government regulations.

You can read the Senate bill here [pdf].

The final result will still be government regulation on the lifespan and final deposition of any object placed in orbit, from nanosats to large manned space stations, but unlike the earlier FCC proposal and House bill, NASA and other government agencies will have to obtain feedback from the commercial space industry before such regulations are imposed.

Sounds great, eh? In truth, this bill in the end still gives full power to the federal government to control the launching of future spacecraft of all sizes. It also leaves the details entirely up to the bureaucracy. If passed Congress would cede its regulatory power to unelected bureaucrats in the executive branch.

The requirement that industry consultation occur simply means that the initial regulations will likely make some sense. Beyond that however the power it bequeaths to the federal bureaucracy in NASA, FAA, FCC, and other agencies will in the long run be still abused.

The need for the establishment of an independent space-faring society, free from odious Earthbound regulation, continues to grow.

ISS spacewalk postponed because controllers had to maneuver station to avoid space junk

9:26 am

An American spacewalk to install new solar panels to ISS yesterday was suddenly scrubbed when ground controllers identified a piece of space junk that was going to fly within a quarter mile of the station.

While flight control teams were preparing for today’s U.S. spacewalk, updated tracking data on a fragment of Russian Fregat-SB upper stage debris showed a close approach to station. Based on this new data, flight control teams directed the crew to stop spacewalk preparations as the ground team stepped into procedures to perform a Pre-Determined Debris Avoidance Maneuver (PDAM.)

Russian controllers successfully used the engines on a docked Progress freighter today to complete the avoidance maneuver, firing those engines for 10 minutes and 21 seconds.

It appears the station was never in any danger.

Chinese upper stage disintegrates in orbit

10:21 am

A Chinese Long March 6 upper stage, launched in on November 11, 2022, has disintegrated into more than 350 in orbit and now pose a threat to other orbiting spacecraft.

The Long March 6A rocket launched from Taiyuan, north China, on Nov. 11, successfully inserting the Yunhai 3 environmental monitoring satellite into its intended orbit.

The upper stage of the rocket, however, apparently suffered a breakup event shortly thereafter. On Nov. 12, the U.S. Space Force’s 18th Space Defense Squadron (18SDS) reported that it was tracking at least 50 discrete pieces of orbital debris from the rocket body. Ongoing tracking from 18SDS, which focuses on space domain awareness, now states that the debris cloud has grown to 350 objects associated with the rocket stage.

Based on the data, it appears the break-up occurred because the stage had an explosive event. It could have been programed to fire its engine to quickly de-orbit it and something went wrong. Or not. The Chinese have not demonstrated much concern about such issues.

Chinese seize space debris being towed by Filippino sailors

8:44 am

According to Filippino Navy officials, after their sailors had captured and was towing a piece of space floating rocket debris back to shore, the Chinese Coast Guard arrived and forcibly seized it, cutting the tow line.

As they were traveling back to the island, “they noticed that a China coast guard vessel with bow number 5203 was approaching their location and subsequently blocked their pre-plotted course twice,” Carlos said in a statement.

The Chinese coast guard vessel then deployed an inflatable boat with personnel who “forcefully retrieved said floating object by cutting the towing line” attached to the Filipino sailors’ rubber boat. The sailors decided to return to their island, Carlos said, without detailing what happened.

Chinese officials denied this, saying they took possession after a “friendly consultation.”

Whether or not the Chinese took this debris by force or not, the fact remains that it existed, indicating once again that China is dropping rocket parts indiscriminately on other nations. In this case the debris probably came from either a first stage or a strap-on booster, released shortly after the launch from a low enough altitude that it doesn’t burn up in the atmosphere.

China: We like dumping out-of-control rockets on your head!

3:49 pm

China has now signaled that it intends to ramp up the launch rate of its Long March 5B rocket, its most powerful rocket but also a rocket with a core stage that falls to Earth out-of-control after each launch, risking injury and damage to others.

Liu Bing, director of the general design department at the China Academy of Launch Vehicle Technology (CALT), told Chinese media that the the Long March 5B, designed for launches to low Earth orbit, would be used together with the Yuanzheng upper stage series to launch multiple satellites for constellations.

Though not clearly stated, the launcher and YZ-2 combination could be used to help deliver high numbers of satellites into orbit for the planned national “guowang” satellite internet megaconstellation.

It is very possible that with the addition of an upper stage, engineers could reconfigure the rocket so that the first stage is shut down and separated earlier so that it immediately falls into an ocean drop zone following launch. At the same time, making sure that drop zone is always over the ocean might be difficult for some polar launches.

What China really has to do is to upgrade the engines on the core stage so that they can be restarted. At present these engines can only be started once, and once shut down they are dead. If the stage reaches orbit — which it has done on all previous launches — there is then no way to control it, and since that orbit is unstable the stage crashes to Earth, who knows where, shortly thereafter. With restartable engines the stage could easily be de-orbited properly.

China has expressed utter contempt for the complaints of other nations about these out-of-control crashes, claiming the risk is infinitesimal. While quite small, it still exists.

Ted Muelhaupt of the Aerospace Corporation said in July that the odds of debris from the reentry following the launch of the Wentian module ranged from one in 230 to one in 1,000. This was more than an order of magnitude greater than internationally accepted casualty risk threshold for the uncontrolled reentry of rockets of one in 10,000, stated in a 2019 report issued by the U.S. Government Orbital Debris Mitigation Standard Practices.

Small or not, China is a signatory to the Outer Space Treaty, and every out-of-control crash has been a violation of that treaty. This behavior clearly makes China a rogue nation, not to be trusted.

Long March 5B core stage crashes in Pacific

8:47 am

According to a tweet from the U.S. Space Force, the out-of-control core stage of China’s Long March 5B rocket has come down in the Pacific Ocean sometime around 4 am (Mountain).

#USSPACECOM can confirm the People’s Republic of China Long March 5B #CZ5B rocket re-entered the atmosphere over the south-central Pacific Ocean at 4:01am MDT/10:01 UTC on 11/4.

The exact location has not yet been revealed, nor do we know yet if any pieces landed on any habitable islands. The odds however of the re-entry causing any damage or injury now appears nil, which is a fortunate thing considering the risks China asked everyone else to take.

Crash prediction for Long March 5B core stage narrows

9:44 am

Crash prediction
Click for original image.

List of the largest uncontrolled re-entries

This morning’s report by the Aerospace Corporation has narrowed the crash time and location for China’s out-of-control Long March 5B core stage to six orbits, about 8 hours, on November 4, 2022, with the prediction centered over a point in the middle of the Indian Ocean.

The company’s graphic to the right shows the orbital tracks. Note that this prediction puts many habitable locations under risk, including parts of the United States, Spain, Africa, and Australia.

Since the crash is now expected tomorrow, expect further updates later today.

The second graphic to the right has also been created by the Aerospace Corporation. It shows the top 20 largest man-made objects that have fallen out-of-control from orbit. Four of the top six were dropped on the world by China, all within the past two years. All but one of the others occurred prior to 1987, before the U.S. and Russia took positive action to prevent such things. The one exception, Phobos-Grunt, was an unexpected failure, its rocket putting it into an unstable orbit rather than sending it to Mars.

China, like the U.S. and Russia, has signed the Outer Space Treaty. That treaty requires each signatory to control the objects it puts in space, and makes it liable for any damage caused by such objects. The U.S. and Russia have both tried very hard to abide by that treaty. China however has thumbed its nose at it.

We must wonder what China will do if this core stage kills someone when it comes down tomorrow.

The crash of China’s Long March 5B core stage: first rough prediction

10:35 am

Long March 5B reentry prediction as of 11/2/22

The Aerospace Corporation has made its first rough estimate of the uncontrolled reentry of the core stage of China’s Long March 5B rocket that launched the Mengtian module to its Tiangong-3 space station on October 31st.

The prediction at present is very uncertain, covering about 20 orbits (about 30 hours) centered on November 5, 2021 over the Atlantic Ocean northeast of Brazil, as shown in the graphic to the right. Though this prediction will eventually narrow down to less than one full orbit, it will never be possible to predict in advance the core stage’s exact impact point. As the margin of error shrinks, the predictions will come more frequently.

At this moment, however, the core stage’s orbit crosses over most of the habitable areas of the Earth, and thus all those regions are under threat.

Watching the launch of the final large module to China’s Tiangong-3 space station

12:10 am

UPDATE: The Mengtian module has been deployed, and is now proceeding to a rendezvous and docking within the next day or so. The core stage is in orbit, and we can only wait over the next few days to find out where it will hit the Earth.

The leaders in the 2022 launch race:

49 SpaceX
47 China
18 Russia
8 Rocket Lab
7 ULA

American private enterprise still leads China 69 to 47, though it now trails the rest of the world combined 74 to 69.

Original post:
—————-
The launch of the final large module for China’s Tiangong-3 space station is scheduled to occur at 12:37 am (Pacific) tonight.

The module is called Mengtian, and once moved to its permanent port will complete the station in its t-shape. The rocket is the Long March 5B, the core stage of which will reach orbit, and then within a week crash uncontrolled somewhere on Earth.

I have embedded the English live stream below. A lot of Chinese propaganda (though not much different from a NASA broadcast). As I understand it, the launch window is instantaneous, so if there are any holds the launch will be scrubbed for the day.

China’s Long March 5B rocket with new space station module is now at launchpad

10:16 am

China’s Long March 5B rocket had now been rolled out to its launchpad, carrying the new Mengtian module for China’s Tiangong-3 space station.

The launch is presently scheduled for October 31, 2022. Assuming China has not upgraded the engines on the rocket’s core stage, that stage will tumble back to Earth, uncontrolled, sometime in the following week. Since it is large enough to survive re-entry, it will hit the ground, thus threatening every habitable location under its orbital path. By allowing this to happen China violates the Outer Space Treaty, to which it is a signatory.

Nor will this likely be the last time China does this. Though this module completes China’s station, as presently designed, this will not be the last Long March 5B launch. China plans to use it put its Hubble-class space telescope into orbit, as well as other things.

ISS dodges space junk from Russia’s November 2021 anti-satellite test

9:46 am

In order for ISS to avoid one of the approximately 585 pieces of space junk still in orbit that were produced when Russia destroyed its defunct Cosmos 1408 satellite in a November 2021 anti-satellite test, engineers fired the engines of a docked Progress freighter yesterday for just over five minutes.

Without the burn the debris would have flown within three miles of the station, too close for comfort or anyone’s margin of error.

According to a report in September, of these 585 pieces, most will burn up in the atmosphere by ’25, with only 38 pieces left afterward to pose a threat to other operating satellites and manned spacecraft.

Head of Commerce’s space office questions new FCC regulations on space junk

10:00 am

Turf war! At a conference yesterday Richard Dalbello, director of the Office of Space Commerce at the Commerce Department, strongly questioned the FCC’s legal authority for its just passed new regulation on the de-orbiting of space junk.

“I think the FCC, for their part, has pushed the boundaries of their authorities pretty aggressively,” he said when asked about what agency should have oversight for issues like that, as his office works to create a civil space traffic management capability. “Although I certainly congratulate them on the depth of their intellectual work,” he said of the FCC and its new order, “a lot of the things that they articulated are probably, arguably, outside their job jar.”

Dalbello’s comments only add to the many turf wars going on in the DC swamp over space regulation. Some in Congress want all space regulation to shift to his office. Others want it to be distributed across a number of agencies in both the military and civilian bureaucracies.

Regardless, Dalbello’s office is the agency that might actually have the legal authority for regulating space junk. And it is certain that the FCC does not have it.

The new in-space repair and refueling industries that are about to revolutionize space exploration

2:57 pm

Robot repair, as imagined in 1979
Robots doing work in orbit, as imagined in 1979

When Orbital ATK announced in 2016 that its robotic Mission Extension Vehicle (MEV) — designed to dock with and extend the life of defunct commercial communications satellites — had won its first contract with Intelsat, that contract award only came after several years of persistent campaigning.

In fact, Orbital ATK had had great difficulties getting any satellite communications company interested. At the time, all communication satellites were in geosynchronous orbit, were expensive to build, but lasted routinely from 10 to 15 years. The satellite companies didn’t see a need to fix them when they ran out of fuel. It seems better to launch a new replacement.

Even after winning that contract with Intelsat, it was still four years before that MEV docked with Intelsat’s satellite, bringing it back to life. In the interim Northrop Grumman (which had purchased Orbital ATK in a merger) had managed just one other contract, even as it had announced upgrades to the MEV to allow it to service many satellites, not just one.

The satellite industry seemed in those days to be largely resistant to the concept of repairing and refueling its older satellites.

No more. We are on the cusp of a major revolution in satellite operations, driven first by innovations like the MEV, but accelerated greatly by the new satellite companies launching low orbit constellations. These new companies are willing to take risks, and thus have also shown an eager desire to link their satellites to a variety of in-space services that they themselves did not wish to provide, from satellite repair and refueling to tug services to space junk removal to quick and controlled de-orbit technologies.

The variety and innovation of this new industry is somewhat astonishing, especially considering how young an industry it is.

Defense to help Commerce create its own ability to track orbital objects

12:40 pm

The Defense and Commerce departments yesterday signed an agreement where Defense will help Commerce create its own capability for tracking of all objects in orbit, from satellites to space junk.

The agreement, the Commerce Department said in a statement, defines how the two departments will work together to implement provisions of Space Policy Directive (SPD) 3 in 2018 that directed commerce to provide space situational awareness (SSA) and space traffic management (STM) services, such as conjunction warnings, currently provided by the U.S. military.

The result of this is that the federal government is now creating a second bureaucracy to do what the military has been doing quite capably for more than a half century. Commerce intends to obtain its data by awarding contracts to private companies, who will do the actual tracking. The irony is that it is very possible the military will eventually sign similar contracts with the same companies, thus paying them twice for the same service. Meanwhile, Washington has an excuse for hiring more people.

Even more ironic, this policy directive was issued during the Trump administration. It might have intended for Commerce to replace the military, but under the Biden administration the federal bureaucracy is being allowed to interpret the policy more broadly, thus allowing both agencies to do the work.

I also guarantee that the Republicans will almost certainly do nothing to change this, should they take over Congress. For the past thirty years this so-called party of small government has done nothing to earn that title. Instead, it has simply engineered the growth of government, in a more subtle and deliberate manner.

FCC proposes new regulation requiring satellites to be de-orbited five years after mission end

9:53 am

The FCC yesterday announced it is considering a new regulation that would require companies to de-orbit defunct satellites in low Earth orbit no more than five years after the satellite’s shut down.

The order, if adopted by commissioners, would require spacecraft that end their missions in or passing through LEO — defined as altitudes below 2,000 kilometers — dispose of their spacecraft through reentry into the Earth’s atmosphere as soon as practicable and no more than five years after the end of the mission. The rule would apply to satellites launched two years after the order is adopted, and include both U.S.-licensed satellites as well as those licensed by other jurisdictions but seeking U.S. market access.

According to the FCC press release [pdf], this new regulation will be discussed at the next public meeting of the commission on September 29, 2022.

Though in general this rule appears a good idea, there are several legitimate objections to it. NASA’s orbital debris office noted that this rule would only reduce space junk by 10%. Others questioned the FCC’s regulatory authority to do this at all, since its main statutory function is not the regulation satellite operations but the use of the frequencies those satellites use.

Debris from Russian anti-sat test causing numerous near Starlink collisions

12:04 pm

According to an official of a company that helps track space junk, the scattered debris from the satellite destroyed by Russia in an anti-satellite test in 2021 has had numerous near collisions with multiple Starlink satellites.

In the Aug. 6 event, Oltrogge said there were more than 6,000 close approaches, defined as being within 10 kilometers, involving 841 Starlink satellites, about 30% of the constellation. It’s unclear how many, if any, of the satellites had to maneuver to avoid collisions.

This conjunction squall was exacerbated by a new group of Starlink satellites. SpaceX launched the first set of “Group 3” Starlink satellites July 10 from Vandenberg Space Force Base into polar orbit, followed by a second set July 22. A third batch of Group 3 satellites is scheduled to launch Aug. 12.

The problem is only going to get worse, as this junk will be in orbit for quite some time.

Australian Space Agency confirms debris is from SpaceX Dragon capsule

10:28 am

Officials from the Australian Space Agency have inspected and confirmed that the debris that landed recently in the southeast Australia came from service module/trunk of a SpaceX Dragon capsule.

The agency had been alerted by Brad Tucker, an astrophysicist from the Australian National University, who first realised the timing and location of the debris falling coincided with a SpaceX spacecraft which re-entered the Earth’s atmosphere at 7am on 9 July, 20 months after its launch in November 2020.

Tucker believes the debris came from the unpressurised trunk of the SpaceX capsule, which is critical to take off but dumped when returning to earth.

This capsule was Resilience, launched on November 15, 2020 on SpaceX’s second manned launch for NASA. The capsule and crew returned in April, 2021. The service module apparently remained in orbit until July 2022, when its orbit decayed.

This service module was considered small enough it would burn up in the atmosphere. That assumption was apparently wrong. Though the pieces caused no damage, SpaceX needs to revise its operations to make sure future service modules will come back over the ocean, just in case sections reach the surface.

Space junk thought to be service module of Dragon manned capsule found in Australia

9:17 am

In news that is related to the impending crash of the Long March 5B core stage, Australian farmers have found scattered space junk pieces that some are claiming are the remains of the service module or trunk section that re-entered on May 5th, the day of the splashdown of SpaceX’s Endurance manned spacecraft.

The debris is most likely the unpressurized “trunk” of the spacecraft, astrophysicist Brad Tucker told Space.com. “Having gone out there and looked at the bits myself, there is not a doubt in my mind it is space junk,” he said in an e-mail. The trunk is designed to send unpressurized cargo into space, and also to support the Crew Dragon during its launch, according to SpaceX (opens in new tab). Half of the trunk includes solar panels that power Dragon when the vessel is in flight or docked to the station. The trunk detaches from the spacecraft shortly before re-entry.

The sonic boom, Tucker said, was widely heard at 7:05 a.m. local time on July 9 and the pieces found near Dalgety were “very close to the tracked path of the SpaceX-1 Crew trunk.”

The problem with this claim is that the sonic boom on July 9th matches no SpaceX launch or re-entry. The material however could be from that Endurance capsule, which returned May 5th, if the trunk once detached did not re-enter until two months later.

If confirmed, this story is surprising, as that service module is thought to be too small to survive re-entry through the atmosphere. It is instead expected to burn up before reaching the ground.
