Scientists rediscover the advantages of nuclear power for moving probes through the solar system

Scientists appear to have once again discovered the advantages of nuclear powered thrusters for moving much heavier interplanetary missions more quickly and more efficiently to the farther reaches of the solar system.

A new paper published last month in the journal Acta Astronautica argues that a fusion-powered drive, capable of delivering propulsion while powering onboard electronics, could be a way to get more power and cargo to outer moons like Titan, and designed a scenario revealing what a DFD-powered [direct-fusion-drive] Titan mission would look like.

A 2021 study from an international research team revealed that a DFD could transport 2,220 lbs to Titan in 31 months. Right now, the Dragonfly mission [to Saturn’s moon Titan] weighs in at about 990 lbs. This new paper says that the Princeton Field-Reversed Configuration (PFRC) concept developed at Princeton Plasma Physics Laboratory is essential for powering the mission.

The irony of this story is that scientists and engineers knew these obvious facts and proposed many versions of nuclear-powered thrusters back in the 1960s. NASA even had a very successful project called NERVA in the late 1960s, with plans to begin using the technology by the 1980s.

All such research was canceled however in the 1970s, partly because of budget cutbacks but mostly because of the paranoia that began developing at that time against using nuclear power for anything. The idea of launching a rocket into space that carried a nuclear rocket engine was considered environmentally too risky.

Has that fear now subsided? We shall see. There are plenty of environmental activist groups that we can expect to immediately oppose such technology. The question will be whether a large enough private industry will evolve capable of exerting its own political weight to resist that opposition.

UK regulators give okay on Viasat’s purchase of Inmarsat

After months of delay, the United Kingdom’s Competition and Markets Authority (CMA) regulators has finally admitted that Viasat’s purchase of Inmarsat would not reduce competition in the communication satellite industry, and has approved the purchase unconditionally.

The evidence analysed by the panel shows that, while Viasat and Inmarsat compete closely– specifically in the supply of satellite connectivity for wifi on flights – the deal does not substantially reduce competition for services provided on flights used by UK customers.

The evidence also shows that the satellite sector is expanding rapidly – a trend that is set to continue for the foreseeable future. This is due to increased demand for satellite connectivity, driven largely by the ever-growing use of the internet by business and consumers.

The CMA press release is a classic of bureaucracy blather. Essentially, it tries to make it sound like this agency did lots of difficult hard work to discover what is patently obvious, that without this merger these two companies will almost certainly not be able to compete with the emerging new satellite communications companies coming on line.

The best thing that the UK could do to encourage competition and new industries in the UK would be to defund this agency, now. Its existence accomplishes nothing other than to stand in the way.

Environmentalists sue FAA, demanding it shut down Boca Chica and Starship

Starship/Superheavy at T+4:02, just after the self-destruct command was issued
Starship/Superheavy at T+4:02, just after the self-destruct command
was issued on April 20, 2023. It also appears to be the fate of SpaceX’s
entire Boca Chica operation, if the environmental radicals get their way.

A group of environmental groups as well as a non-profit corporation calling itself the Carrizo/Comecrudo Nation of Texas, Inc, today filed a lawsuit against the Federal Aviation Administration FAA), demanding it shut down SpaceX’s Boca Chica facility and block all further Superheavy/Starship launches.

You can read the lawsuit here [pdf]. Its essence is contained in these two paragraphs:

The area surrounding the SpaceX facility at Boca Chica is a biologically diverse and essential habitat area for many species, including federally protected wildlife and animals that are considered sacred to the Carrizo/Comecrudo People, such as the critically endangered ocelot. The SpaceX facility is smack in the middle of publicly owned conservation, park, and recreation lands, including a National Wildlife Refuge, two State Parks, a State Wildlife Management Area, and a State Coastal Preserve. These lands are of extraordinary conservation value for a range of federally and state lists wildlife and other protected species such as migratory birds. Bird species from both the Central and Mississippi flyways converge there, making it an essential wintering and stopover area for migratory birds as they move north and south each year.

SpaceX activities authorized in the FONSI/ROD [the environmental reassessment issued last year] have and will adversely affect the surrounding wildlife habitat and communities. In addition to harm from construction activities and increased vehicle traffic, rocket launches result in intense heat, noise, and light pollution. Furthermore, the rocket launches and testing result in explosions which spread debris across surrounding habitat and cause brush/forest fires — including one that recently burned 68 acres of adjacent National Wildlife Refuge. The FAA calls these explosions “anomalies,” but in fact they occur frequently, with at least 8 over the past 5 years. FAA acknowledged that many more such “anomalies” are expected over the next 5 years. The U.S. Fish and Wildlife Service has found that prior SpaceX rocket explosions harmed protected wildlife and designated habitat in violation of the Endangered Species Act (ESA).

In other words, rockets and launch sites should never be placed inside wildlife refuges, because such activity is detrimental to wildlife.

A more false statement cannot be made. Under this conclusion the launch facilities at Cape Canaveral, which have been operating in the middle of a wildlife refuge now for more than six decades, should be shut down immediately. All the wildlife there must certainly be dead!

With the federal bureaucracy gleefully sharpening its knives to shut down Boca Chica, SpaceX should quickly shift Starship/Superheavy operations to Florida

Superheavy still going strong, shortly after Max-Q
Superheavy still going strong, shortly after Max-Q

The results of the spectacular test launch last week of SpaceX’s Superheavy/Starship heavy lift rocket was predictable in almost all ways.

First, everyone knew that it was highly unlikely that the launch would do everything intended. This was the first time ever that SpaceX had fired all 33 Raptor-2 engines at the base of Superheavy, at full power. It was the first time ever that this firing took place with Starship stacked on top. It was the first time ever that the entire stack was fueled. It was the first time ever that this rocket — the world’s most powerful (twice as powerful as the Saturn-5 and about three times more powerful than SLS) — had every launched.

The number of unknowns were gigantic, which was exactly why SpaceX needed to do the launch. The company’s engineers needed to find out what they didn’t know about Superheavy in order to refine their engineering so that Superheavy will be more likely for success in its next launch. They also needed to find out what such a launch would do to their preliminary launchpad, in order to refine its engineering as well so that future launches could take place with little or no damage.

Thus, it is not surprising that there were surprises. The most significant was the actual amount of success. Superheavy functioned far better than anyone could have dreamed, retaining flight control through max-q and then flying for almost three minutes before Starship failed to separate and the entire stack lost control and had to be destroyed. Most of its engines worked, though discovering the reasons for the handful that failed will be a prime question in the subsequent investigation.

The second unsurprising thing about this launch is the reaction of the federal bureaucracy, run by Democrats and the Biden administration. It has quickly moved in to squelch any further launches at Boca Chica, likely for a considerable time. The FAA immediately initiated its own investigation while grounding all further launches from Boca Chica. The Fish & Wildlife Service has now begun detailing, almost gleefully, the amount of ground damage the launch caused, including ripping out the concrete base below the rocket and flinging chunks of debris hundreds of feet away as well as depositing a cloud of sand dust on everything up to 6.5 miles from the launchpad.

This quote however is significant, and tells us the real truth:

FAA issues Starship launch license; SpaceX schedules launch for April 17th

Starship stacked on top of Superheavy
Starship prototype #24 stacked on top of Superheavy prototype #7

FAA just sent out an email notice announcing that it has issued SpaceX the launch license for the first orbital test launch of Superheavy/Starship.

After completing an evaluation of all applicable Vehicle Operator License requirements, the Federal Aviation Administration (FAA) issued a commercial Vehicle Operator License to SpaceX for launches of the Starship/Super Heavy Launch Vehicle Program in Cameron County, TX.

The affected environment and environmental impacts of Starship/Super Heavy operations at the Boca Chica Launch Site had been analyzed in the 2022 Final Programmatic Environmental Assessment for the SpaceX Starship/Super Heavy Launch Vehicle Program at the SpaceX Boca Chica Launch Site in Cameron County, Texas. Since the 2022 Programmatic Environmental Assessment (PEA), SpaceX provided the FAA with additional information regarding Starship’s planned landing, Super Heavy’s planned soft water landing, and the Launch Pad Detonation Suppression System. In accordance with FAA Order 1050.1F, Environmental Impacts: Policies and Procedures, the FAA prepared the Written Re-evaluation of the 2022 Final Programmatic Environmental Assessment for the SpaceX Starship/Super Heavy Launch Vehicle Program at the Boca Chica Launch Site in Cameron County, Texas to describe and evaluate this additional information.

Based on the Written Re-Evaluation, the FAA concluded that the issuance of a vehicle operator license for Starship/Super Heavy operations conforms to the prior environmental documentation, that the data contained in the 2022 PEA remains substantially valid, that there are no significant environmental changes, and all pertinent conditions and requirements of the prior approval have been met or will be met in the current action. Therefore, preparation of a supplemental or new environmental document is not necessary to support the Proposed Action.

In plain English, the FAA (and other federal agencies) have finally agreed that this launch will do nothing to change the conclusions of the environmental reassessment report that was approved in June 2022. That these agencies decided apparently decided to rehash that approved environmental reassessment for a launch that was also approved in that reassessment suggests that there are individuals in these agencies salivating for an opportunity to squelch SpaceX.

SpaceX has now set April 17, 2023 as the launch date, with its live stream going live in two days. I will embed that live stream late on April 16, 2023, for those who wish to watch it here.

FCC makes official its regulatory power grab beyond its statutory authority

We are here to help you! The FCC yesterday officially launched a new stand-alone Space Bureau which will be focused on institutionalizing the many new regulations the FCC has proposed for controlling how satellites are built and de-orbited.

The Space Bureau was carved out of the FCC’s International Bureau to help the regulator handle its increasing workload in the industry. The restructuring effectively splits the International Bureau into two units: the Space Bureau and the Office of International Affairs (OIA) that will handle the FCC’s work with foreign and international regulatory authorities more generally.

While the bureau’s first leader, Julie Kearney, claimed the goal of this reorganization is to streamline licensing, she also made it clear that she will also be using her new position to make the proposed new regulations on satellite construction and deorbit the law of the land, even though Congress never gave the FCC this particular regulatory power.

Based on Congress’s general weakness and willingness in the past half century to cede power to the administrative state, Kearney and the FCC will likely succeed. For example, though a bill has been introduced in Congress to address the FCC’s power grab, it basically endorses it.

In other words, the bureaucrats in DC now essentially write the laws, Congress bows meekly to approve them, and then the bureaucracy moves to enforce them.

Starship orbital test flight delayed one more week due to FAA delays

According to a tweet yesterday by Elon Musk, the first orbital test flight of Starship/Superheavy has been delayed again.

Starship launch trending towards near the end of third week of April

Musk had made it clear in an April 8th tweet the cause of this delay or any other delays:

Starship is ready for launch. Awaiting regulatory approval

Musk needs to be somewhat diplomatic as it will not help him to make federal bureaucrats his enemies. What he is doing here is subtly letting everyone know the sole cause of the delay, in order to press the FAA to get a move on, without saying so directly. He leaves that to others, such as myself, to say it instead.

I fear that the FAA is now demanding that it must look at the data from any wet dress rehearsal countdown, including the short engine burst that Superheavy will likely do at T-0, before it will issue the permit. If so, we could see more than a week delay. The launch should easily slip to late May if not later.

The absurdity of this is that it is utterly pointless for FAA bureaucrats to look at any of this data. What do they know? Nothing. If something was significantly wrong SpaceX engineers would know far sooner, and delay the launch themselves.

The delays seen in issuing this one launch license however give us a nice picture of what it will be like for the launch industry once the moratorium on heavy regulations by the FAA and other federal agencies expires on October 1, 2023. Expect a substantial slowdown in development and launches, with many of the new companies about to become operational instead going bankrupt in a replay of the destruction of Virgin Orbit by the UK’s Civil Aviation Authority.

Report recommends Congress allow full regulation of commercial human spaceflight

The modern instruction manual for America
The modern instruction manual for America

A new report by the RAND corporation has recommended that Congress allow the moratorium on full regulation of commercial human spaceflight, established by the Commercial Space Launch Amendments Act of 2004 and extended several times, to expire on October 1, 2023.

That recommendation came despite a lack of progress on voluntary standards and key industry metrics. While standards development organizations like ASTM International and ISO have published 20 standards related to commercial spaceflight, the RAND report noted that “companies have yet to clearly or consistently adopt them in a manner that can be confirmed or verified publicly.” A diversity of technical approaches also hinders the development and implementation of standards.

The report also found that while the FAA had developed key industry indicators to assess readiness for adopting safety regulations, there were no goals for those indicators to determine when it was time to implement regulations. “It is, therefore, difficult to assess whether there has been progress toward meeting key industry metrics when there are not clear targets that could be met,” the report concluded.

Despite that lack of progress on standards or metrics, the RAND report nonetheless concluded that allowing the learning period to expire this year was the best approach. Doing so, it argued, would allow FAA and industry to start the process of developing safety regulations in a gradual manner and avoid a rush to regulate imposed by Congress should a high-profile accident take place while the learning period is still in effect.

It also recommended additional resources for the FAA to support that regulatory process, but did not quantify an increase in the budget for or personnel assigned to its Office of Commercial Space Transportation, or AST. [emphasis mine]

Starship now stacked on launchpad

Starship stacked on top of Superheavy

In preparation for a final wet dress rehearsal countdown followed by its first launch, Starship has now been stacked on top of Superheavy at SpaceX’s launchpad at Boca Chica, Texas.

The picture to the right is a screen capture from a short video Elon Musk posted on Twitter. SpaceX had also tweeted that its “Team is working towards a launch rehearsal next week [April 10-11] followed by Starship’s first integrated flight test ~week later pending regulatory approval.”

At this time the FAA has still not issued the launch license. By announcing its plan to launch the week of April 17th, Musk and SpaceX puts pressure the government bureaucracy to get a move on.

Shetland Spaceport now faces same regulatory hurdles that destroyed Virgin Orbit

The new Shetland spaceport, Saxavord, is right now attempting to get launch approvals from United Kingdom’s Civil Aviation Authority (CAA), the same agency that dithered for six months approving a Virgin Orbit launch, thus causing the bankruptcy of that company.

According to Saxavord’s CEO, the spaceport has two launches aiming to launch before the end of this year, assuming the CAA can get its act together and give its approval. This quote however is worrisom:

The Saxavord spaceport says it is “still on track” to receive its necessary licences from the sector’s regulator before the summer. This relates to applications to the Civil Aviation Authority for range and spaceport licences.

Meanwhile SaxaVord CEO Frank Strang said the company is also on track for two rocket launches this year – “albeit they have moved slightly to the right”. [emphasis mine]

The delays could be coming from the rocket companies themselves. One of those companies is the German startup, Rocket Factory Augsburg, which has leased exclusive use of one launchsite. The other is the American startup ABL, which has had one launch attempt from the U.S. that failed.

Based on the CAA’s track record however the delays are just as likely coming from it. The CAA began this licensing process in November 2022, and is not done yet six months later.

FAA issues travel advisory for Boca Chica for April 10, 2023 Starship launch

Though the FAA has not yet issued the launch license to SpaceX, allowing it to do the first orbital launch test of its Superheavy/Starship rocket, the agency today did issue a travel advisory for the Boca Chica area for April 10-11, 2023, in connection with this launch.

The FAA advisory is here. Scroll down to see the space activities section, which includes this information:

SPACEX STARSHIP SUPERHEAVY BOCA CHICA, TX
PRIMARY: 04/10/23 1310-1745Z
BACKUP(S): 04/11-12/23 1310-1745Z

Based on this information, we should expect the FAA launch license to be publicly announced any moment.

Hat tip BtB’s stringer Jay, who trolls Twitter so I don’t have to.
