FAA issues new revised regulations for private commercial manned space

9:48 am

The FAA on September 28, 2023 issued new revised safety regulations for the emerging private commercial manned space industry, updating the regulations first put forth in 2014.

The recommendations, which are the first since 2014, cover the gamut across design, manufacturing, and operations, and are based on lessons learned during the NASA Commercial Crew program, as well as recent commercial space fights, the FAA said Friday. “AST [the FAA office that handles commercial space] is issuing Version 2 of this document because significant progress has been made in the commercial human space flight industry since 2014, the year Version 1 was issued.”

These new recommendations were worked out by a committee that included many of the private companies that now fly space passengers, such as SpaceX, Virgin Galactic, Blue Origin, and Boeing. Thus, the changes likely make some sense.

At the same time, it seems the effort to regulate has accelerated since Joe Biden became president. Under Trump there was a concerted effort to limit the impact of new regulations on this new space industry. Under Biden, it appears new regulations arrive almost weekly, and as a result there appears to be a significant slow down in development by new space companies.

FCC fines Dish for failing to put a geosynchronous satellite in its proper graveyard orbit

9:39 am

The FCC on October 2, 2023 announced it is fining Dish Network $150K for failing to raise the orbit of one of its dying geosynchronous satellites so that it was in a proper graveyard orbit and out of the way.

The settlement includes an admission of liability from Dish for leaving EchoStar-7 at 122 kilometers above its operational geostationary arc, less than halfway to where the satellite broadcaster had agreed. EchoStar-7 could pose orbital debris concerns at this lower altitude, the FCC warned.

The regulator said it approved a plan from Dish in 2012 to move the satellite at the end of its mission 300 kilometers above geostationary orbit, which is about 35,786 kilometers above the Earth. Dish had estimated it would need to start moving the satellite in May 2022 to ensure it had enough fuel for the trip after two decades in orbit — but just three months ahead of the planned move the company found insufficient propellant remaining.

It is routine for satellite companies to raise the orbits of their geosynchonous satellites when their lifespan is over in order to make room for future satellites. This higher orbit, long dubbed a graveyard orbit, is presently filled with many past satellites no longer in use (though the refueling and reusing of some is now taking place).

What makes this story different is the fine. The FCC has claimed it has the right to regulate the de-orbiting plans for all satellites, even though its statutory authority does not include that right. This fine is the first since the agency made that claim. That Dish settled rather than fight was likely a decision by managment to choose the lesser evil. Even though the courts would likely cancel the fine, the fight would cost as much as the fine, and there is a chance Dish would lose. As the saying goes, better to pay the two dollars than end up in jail.

As a result, this government agency has now established a precedent whereby it can regulate and even fine private companies for not doing what it dictates when it comes to decommissioning satellites, even though no law was ever passed giving it that power. And the FCC agrees.

“This is a breakthrough settlement,” FCC Enforcement Bureau Chief Loyaan Egal said in a statement, “making very clear the FCC has strong enforcement authority and capability to enforce its vitally important space debris rules.”

The unelected administrative state continues its unstoppable growth in power.

Northrop Grumman cancelling its NASA space station project?

9:22 am

According to anonymous sources, Northrop Grumman — one of four company partnerships chosen by NASA to build private commercial space stations to replace ISS — is considering cancelling its project for NASA.

At the International Astronautical Congress meeting this week in Azerbaijan, sources report that there is widespread speculation that one of these four companies, Northrop Grumman, is dropping out of the competition. Northrop’s plan had been to leverage its successful Cygnus spacecraft design to build a free-flying space station.

However, Northrop no longer plans to do so. Rather, it will join the venture backed by Voyager Space, which is partnering with Europe-based Airbus to develop a commercial space station. It’s likely that Northrop would provide cargo transportation services, with Cygnus as part of the team. Officials from Voyager and Northrop Grumman declined to comment on the change in strategy, which could be announced soon.

The original four were Axiom, Voyager Space (then called Nanoracks), Northrop Grumman, and Blue Origin. By teaming up with Voyager Space the number would drop to three, with Northrop simply providing freighter service to Voyager’s station.

Nor is this the only rumored change to these station projects. Last week sources suggested that the partnership between Blue Origin and Sierra Space was breaking up. If so, it remains unclear how that would effect its project for NASA.

These changes to the four proposed NASA stations would leave only Axiom’s space station unchanged and on its original course. Meanwhile, another company, Vast, is developing its own independent station, and SpaceX is considering developing a space station version of Starship.

All these shifts and changes are not to be unexpected, nor are they really bad news. They simply indicate the uncertain nature of any new product, even if that product is as unconventional as a private space station.

Psyche engineers discover and fix a major thruster problem only two weeks before launch

9:03 am

In a stroke of luck, the engineering team for the asteroid probe Psyche discovered an attitude thruster problem only two weeks before launch that could have destroyed the mission, and were able to fix it quickly.

The issue was discovered during pre-flight tests that showed the settings used to operate the thrusters were incorrect. At the planned 80 percent power level, analysis indicated higher-than-expected temperatures could cause damage.

As it turned out, the fix did not require any hardware or software changes. Just an updated table of parameters used by the probe’s flight computer, instructing it to fire the thrusters at what amounts to a lower power level. Maneuvers will take longer to complete, but that will not affect the mission.

Nonetheless, this problem should not have been discovered so late, and suggests that the management issues from other software problems that forced a year delay in the launch last year have not been completely solved. If I was the project scientist for this mission, I would be very uncomfortable about its future.

Hopefully, no more serious problems will occur, and after its Falcon Heavy launch on October 12 it will fly past Mars to aim for an August 2029 arrival at the metal asteroid Psyche.

SLIM leaves Earth orbit and is on its way to the Moon

8:51 am

SLIM's planned route to the Moon

The Japanese lunar lander SLIM fired its engines on September 30, 2023 to begin its journey to the Moon. The map to the right indicates the planned route after this trans-lunar injection burn, first flying past the Moon to put it on a trajectory that will bring it back to the Moon at the proper speed and direction for its landing several months hence.

The main goal of this mission is engineering, to test the ability of an autonomous unmanned spacecraft to land precisely within a small target zone about 300 feet across. If proven, this ability will make it possible to send unmanned landers to many places that are presently impossible due to their rough topography.

The route that SLIM is taking to the Moon is also unusual, and is probably also an engineering test of its own. Flybys of planets to change a spacecraft’s path is not a new technique, but in the past it has been used to slingshot the probe to another object, not send it back to that planet.

ESA completes investigation of Vega-C rocket failure

5:10 pm

The European Space Agency (ESA) today released its completed investigation of December 2022 launch failure of its Vega-C rocket’s second stage.

One of the recommendations was to implement a (delta-)qualification of the nozzle with a new Carbon-Carbon throat insert material different from that previously used on the Zefiro40, the solid rocket booster of the Vega-C second stage. On 28 June 2023, a static firing test of the modified Zefiro40 engine took place at the test bench in Salto di Quirra in Italy. During the test the engine nozzle suffered significant damages.

ESA Director General Josef Aschbacher has set up an Independent Enquiry Commission chaired by the ESA Inspector General, Giovanni Colangelo, and composed of experts from CNES, ASI, ESA, Arianespace and academia to understand the cause of the test anomaly and propose recommendations.

The Independent Enquiry Commission concluded that in the current design of the nozzle, the combination of the geometry of the Carbon-Carbon throat insert and the different thermo-mechanical properties of the new material caused progressive damage of other adjacent nozzle parts and a progressive degradation eventually leading to the nozzle’s failure.

In other words, the changes implemented based on the initial investigation that was completed in March did not work. The nozzle needs to redesigned, and will also require at least two more static fire engine tests to be certified.

At the moment ESA officials are predicting that Vega-C will resume launches in the fourth quarter of next year, but do not put any money on that prediction.

Pushback: Gestapo police chief who raided Kansas newspaper in August suspended

12:52 pm

Police Chief Gideon Cody, proud to emulate Nazi tactics
Police Chief Gideon Cody, proud to emulate
Nazi tactics

They’re coming for you next: For his part of a Gestapo-like raid in August of the town’s newspaper, the police chief of the town of Marion in Kansas, Gideon Cody, was suspended from his job on September 30, 2023 by the town’s mayor, Dave Mayfield.

Cody’s suspension is a reversal for the mayor, who previously said he would wait for results from a state police investigation before taking action. Vice-Mayor Ruth Herbel, whose home was also raided Aug. 11, praised Cody’s suspension as “the best thing that can happen to Marion right now” as the central Kansas town of about 1,900 people struggles to move forward under the national spotlight.

At the moment is not clear whether Cody’s suspension is with or without pay.

This is a followup on a previous blacklist column, posted in August when that raid occurred. The raid, which not only included the newspaper’s offices but the homes the town’s vice mayor, the newspaper’s 98-year-old owner, Joan Meyer (resulting in her death the next day from a heart attack), and one reporter.

As noted then, the raid was uncalled for on numerous levels. » Read more

Layered ice sheets on Mars?

Overview map

Layered ices sheets on Mars?

Cool image time! The picture to the right, cropped, reduced, and sharpened to post here, was taken on June 22, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The white spot near the center of the overview map above marks its location, deep inside the 2,000-mile-long region in the northern mid-latitudes I call glacier country, as everything there seems covered with glacial features of some kind. All the features in this picture are smaller than 50 feet high, based on the resolution of the topographical data obtained by Mars Global Surveyor in the 1990s.

What makes this picture interesting are the layers, made most obvious in the terraced mesa in the upper left. Surrounding this mesa for dozens of miles in all directions are similar layered features, all suggesting that the glacial ice sheets that appear to coat this region have either have been sublimating away over time, or when growing grew less with each subsequent growth cycle.

Though both have or are likely happening, the latter most likely explains the terraces, as there is a lot of evidence on the surface of Mars showing that each subsequent growth cycle produced smaller glaciers and ice layers.

From the perspective of future colonists, this picture once again shows that water will readily accessible on Mars, as long as you travel north or south of the equator at least 30 degrees of latitude. This location is at 42 degrees north, and is very typical of this whole region.

Perseverance spots a Martian dust devil

9:15 am

Panorama showing dust devil
Click for movie.

During their normal use of Perseverance’s navigation cameras to survey upcoming terrain for future travel, the rover’s science team captured a short movie of a Martian dust devil as moved across a nearby ridgeline. I have annotated a still from that move above to indicate the dust devil.

The lower portion of a Martian dust devil was captured by one of the Navcams on NASA’s Perseverance rover on Aug. 30, 2023, the 899th Martian day, or sol, of the mission. The video, which has been enhanced in order to show maximal detail, was sped up 20 times and composed of 21 frames taken four seconds apart.

Using data from the imagery, mission scientists determined that the dust devil was about 2.5 miles (4 kilometers) away, at a location nicknamed “Thorofare Ridge,” and moving east to west at a clip of about 12 mph (19 kph). They calculated its width to be about 200 feet (60 meters). While only the bottom 387 feet (118 meters) of the swirling vortex are visible in the camera frame, scientists used the dust devil’s shadow to estimate its full height at about 1.2 miles (2 kilometers).

This Perseverance movie is not the first to catch a dust devil on the surface. Both Curiosity and Perseverance have done so previously, and I think the smaller earlier rovers Opportunity and Spirit did so as well. Nonetheless, this mini-twister provides more information about the atmosphere of Mars.

Stopgap budget bill includes three-month extension of regulatory “learning-period”

9:00 am

The stopgap 45-day continuing resolution passed by Congress on September 30, 2023 also included a three-month extension of regulatory “learning-period” first established in 2004 and extended several times since then.

Among the provisions in that FAA reauthorization was a three-month extension of the existing restrictions on the FAA’s ability to regulate safety for commercial spaceflight participants. That restriction, often called a “learning period” by the industry, was set to expire Oct. 1 but now runs until Jan. 1.

It must be noted that this so-called limitation on FAA regulation of commercial spaceflight really does not exist any longer, no matter what law Congress passes. The administrative state really runs the show now, and both the FAA and Fish & Wildlife have decided heavy regulations are required, and are imposing such controls over SpaceX’s Superheavy/Starshp test program, while the FAA by itself is imposing strict regulation on Blue Origin’s New Shepard suborbital spacecraft. The result is a slowdown in launches for both, extending months to a year.

It also appears that this heavy regulation is squelching launches of new rockets. Last year four new rocket startups attempted new launches (Astra, ABL, Firefly, Relativity), some making multiple attempts. This year, such test flights have essentially ceased, with only Firefly completing one launch for the military. Worse, two of those companies (Astra and Relativity) have abandoned their rockets entirely, claiming they are building new bigger versions, but one must now wonder.

The long term historical significance of these facts extends far beyond the space industry. Increasingly the unelected bureaucracy in Washington is taking on powers it is not supposed to have, while Congress (which is delegated those powers) increasingly is irrelevant. The shift in power signals a major reshaping of American governance, in a direction that is not good for freedom or the fundamental concepts that established the country and made it a success.
