Canucks. In. Space – “racist, exploitative, elitist, and environmentally destructive”

Filed under: Cancon, Military, Politics, Space — Tags: , , , , , — Nicholas @ 03:00

In the National Post, Tristin Hopper‘s First Reading on a recently commissioned report for the Canadian Armed Forces on space exploration from an intersectional feminist viewpoint:

As Canada prepares to send an astronaut on the first manned moon mission in more than 50 years, its own military has commissioned a $32,250 report on how space exploration may actually be “racist, exploitative, elitist, and environmentally destructive”.

The 48-page report, entitled Hidden Harms: Human (In)security in Outer Space, concludes that human usage of space is currently “masculine, militarized and state-based”.

The authors also bemoan a space exploration field that is beholden to colonial concepts such as “technospeak” and “expertise”, and which doesn’t give appropriate weight to “spirituality, astrology, and cosmology, the last of which views celestial bodies in space as animated beings and not mere objects”.

As such, the report concludes that space will continue to be a realm of “hidden violence” against the world’s marginalized until “gender, race, class, ability, and sexuality” can be put at “the centre” of how decisions are made in the cosmos.

“Leadership is needed to normalize inclusion of different perspectives,” reads a conclusion.

The report has very little positive to say about the current state of human space exploration or space technology.

The whole endeavour is criticized as “technology-biased” because it fails to consider “gendered effects”. It’s “geography-biased”, because it doesn’t include equal participation from poorer countries.

It “normalize(s) violence and exploitation” by using language that depicts “outer space as a hostile and desolate environment that is unpeopled/inhuman and controlled so that it can provide an extractable resource”.

The construction of launch pads, satellite receivers and other ground infrastructure causes “disproportionate harm to Indigenous communities by severing their connection to ancestral lands”.

The report is also deeply critical of the fact that space is disproportionately inhabited by able-bodied males from wealthy countries. “Existing approaches are ahistorical and thus invisibilize diverse stakeholders and voices,” it reads.

Hidden Harms contains little to no discussion of the technical aspects of space exploration or technology. The word “rocket”, for instance, appears only once in a footnote in relation to how a falling rocket stage could hurt Inuit people. The word “orbit” appears in the text just once, when referencing how states could impose extraterrestrial harm by “permanently damaging objects on orbit”.

Nevertheless, the report is clear that all of these technical considerations should become secondary to “intersectional, decolonial, and humanitarian perspectives”.

“We must make space for the unfamiliar and the uncomfortable,” it reads.

It’s hardly surprising that an “intersectional feminist” view of space exploration would be harshly negative — what is surprising is that the Canadian Armed Forces paid to have this intellectual drivel written. A bit over $30k isn’t even a rounding error for the federal government, but as an indicator of just how federal bureaucrats are spending their departmental budgets it does seem to indicate that there’s a lot of fat in those budget numbers.

Mining the moon would be “harmful” to indigenous people, say activists

Filed under: Media, Politics, Science, Space, USA — Tags: , , , — Nicholas @ 03:00

Among the many, many things that are said to be harmful to indigenous culture we’re now told to include any kind of Lunar exploitation as modern colonialism:

Artist’s conception of Helium-3 mining on the surface of the Moon.

Humans have boldly ventured beyond the Earth into space for more than half a century now. It’s a testament to the ambition of the modern world.

And today, humanity is still more ambitious. A new space race is underway between the US and China to mine the Moon for rare metals. NASA is even hoping to establish a long-term presence on the Moon and eventually send humans to Mars.

But it seems that some scientists-cum-activists, in hock to identity politics, want to rein in that ambition. Speaking ahead of a US conference on the ethics of space exploration, held by the American Association for the Advancement of Science (AAAS) last week, astrobiologist Dr Pamela Conrad told the Guardian that space exploration, particularly efforts to mine the Moon, is in danger of becoming an exercise in “colonialism” and “exploitation”. Conrad warned that “if something that’s not here [on Earth] is seen as a resource, just ripe to be exploited, then that [perpetuates] colonialism”.

Conrad’s fellow panellist at the conference, Dr Hilding Neilson, went even further. According to Neilson, a member of the Native American Mi’kmaq people, indigenous people have a deep connection with celestial bodies like the Moon. They therefore have a more profound and, by implication, superior “way of knowing” the Moon compared with those advocating space exploration. The latter merely see the Moon “as a dead object to be conquered”, Neilson says – meaning that those advocating space exploration are “essentially cheering on the history of colonialism”.

There are so many problems with this argument it’s difficult to know where to start. Both Conrad and Neilson appear to be using the specific and brutal practice of “colonialism” to describe – and demonise – humanity’s attempt to master nature in general. That’s a flawed enough approach to take to the history of our growing mastery of nature on Earth. But it’s even more flawed in the context of space.

After all, there’s one big difference between laying claim to the resources of other countries under colonialism and attempting to mine the Moon – nobody lives on the Moon! So no one would be “exploited” or “colonised” if humans were to mine it. Space exploration is therefore not the same as colonialism.

Charles Stross predicts that Elon Musk will become a multi-trillionaire

Charles Stross isn’t exactly a fan of Musk’s, but he outlines why he thinks Musk is on a potentially multi-trillion dollar path:

So, I’m going to talk about Elon Musk again, everybody’s least favourite eccentric billionaire asshole and poster child for the Thomas Edison effect — get out in front of a bunch of faceless, hard-working engineers and wave that orchestra conductor’s baton, while providing direction. Because I think he may be on course to become a multi-trillionaire — and it has nothing to do with cryptocurrency, NFTs, or colonizing Mars.

This we know: Musk has goals (some of them risible, some of them much more pragmatic), and within the limits of his world-view — I’m pretty sure he grew up reading the same right-wing near-future American SF yarns as me — he’s fairly predictable. Reportedly he sat down some time around 2000 and made a list of the challenges facing humanity within his anticipated lifetime: roll out solar power, get cars off gasoline, colonize Mars, it’s all there. Emperor of Mars is merely his most-publicized, most outrageous end goal. Everything then feeds into achieving the means to get there. But there are lots of sunk costs to pay for: getting to Mars ain’t cheap, and he can’t count on a government paying his bills (well, not every time). So each step needs to cover its costs.

What will pay for Starship, the mammoth actually-getting-ready-to-fly vehicle that was originally called the “Mars Colony Transporter”?

Starship is gargantuan. Fully fuelled on the pad it will weigh 5000 tons. In fully reusable mode it can put 100-150 tons of cargo into orbit — significantly more than a Saturn V or an Energiya, previously the largest launchers ever built. In expendable mode it can lift 250 tons, more than half the mass of the ISS, which was assembled over 20 years from a seemingly endless series of launches of 10-20 ton modules.

Seemingly even crazier, the Starship system is designed for one hour flight turnaround times, comparable to a refueling stop for a long-haul airliner. The mechazilla tower designed to catch descending stages in the last moments of flight and re-stack them on the pad is quite without precedent in the space sector, and yet they’re prototyping the thing. Why would you even do that? Well, it makes no sense if you’re still thinking of this in traditional space launch terms, so let’s stop doing that. Instead it seems to me that SpaceX are trying to achieve something unprecedented with Starship. If it works …

There are no commercial payloads that require a launcher in the 100 ton class, and precious few science missions. Currently the only clear-cut mission is Starship HLS, which NASA are drooling for — a derivative of Starship optimized for transporting cargo and crew to the Moon. (It loses the aerodynamic fins and the heat shield, because it’s not coming back to Earth: it gets other modifications to turn it into a Moon truck with a payload in the 100-200 ton range, which is what you need if you’re serious about running a Moon base on the scale of McMurdo station.)

Musk has trailed using early Starship flights to lift Starlink clusters — upgrading from the 60 satellites a Falcon 9 can deliver to something over 200 in one shot. But that’s a very limited market

As they say, read the whole thing.

QotD: Heinlein’s “Future History”

Filed under: Books, Quotations, Space, USA — Tags: , , , , — Nicholas @ 01:00

I’ve been planning to write about Elon Musk’s Bowie-blasting space car ever since the video footage was transmitted back to Earth in the middle of this week. But I did not even notice until I sat down to the job that I have also been rereading Robert A. Heinlein’s “Future History” short-story cycle. This is not exactly a coincidence: I go back to the Future History every few years. This time I had one of those “Surprise! You’re old!” moments upon realizing that my cheap trade paperback of The Past Through Tomorrow, a collection of the Future History stories, must be 30 years old if it’s a day.

Written between 1939 and 1950 for quickie publication in pulp magazines, the Future History is a series of snapshots of what is now an alternate human future — one that features atomic energy, solar system imperialism, and the first steps to deep space, all within a Spenglerian choreography of social progress and occasional resurgent barbarity. It stands with Isaac Asimov’s Foundation trilogy as a monument of golden-age science fiction.

In some respects the Future History has not aged any better than one might expect. Like other young nerds who created the science-fiction canon, Heinlein was interested in rocketry before it was thought to have any practical use. And Heinlein was really, really good at acquiring or faking expert knowledge of those topics in which he happened to get interested. The man knew his Tsiolkovsky.

The result, in the key story of the Future History, is an uncannily accurate description of the design and launch of a Saturn V rocket. (Written before 1950, remember.) But because Heinlein happened not to be interested in electronic computers, all the spacefaring in his books is done with the aid of slide rules or Marchant-style mechanical calculators (which, in non-Heinlein history, had to become obsolete before humans could go to Luna at all). Heinlein sends people to colonize the moon, but nobody there has internet, or is conscious of its absence.

QotD: Elon Musk as a real life Delos D. Harriman

Filed under: Books, Business, Quotations, Space, USA — Tags: , , , , , , — Nicholas @ 01:00

The “key story” [in Robert Heinlein’s “Future History” stories] I just mentioned is called “The Man Who Sold The Moon.” And if you’re one of the people who has been polarized by the promotional legerdemain of Elon Musk — whether you have been antagonized into loathing him, or lured into his explorer-hero cult — you probably need to make a special point of reading that story.

The shock of recognition will, I promise, flip your lid. The story is, inarguably, Musk’s playbook. Its protagonist, the idealistic business tycoon D.D. Harriman, is what Musk sees when he looks in the mirror.

“The Man Who Sold The Moon” is the story of how Harriman makes the first moon landing happen. Engineers and astronauts are present as peripheral characters, but it is a business romance. Harriman is a sophisticated sort of “Mary Sue” — an older chap whose backstory encompasses the youthful interests of the creators of classic pulp science fiction, but who is given a great fortune, built on terrestrial transport and housing, for the purposes of the story.

Our hero has no interest in the money for its own sake: in late life he liquidates to fund a moon rocket, intending to take the first trip himself, because he is convinced the future of humanity depends on extraterrestrial expansion of the human species. (Also, the guy just really loves the moon.)

The actual stuff of the story consists of the financial and promotional chicanery that Harriman uses to leverage his personal investment. Harriman uses sharp dealing with governments, broadcasters, political groups: he plants fake news about diamonds on the moon to blackmail (a disguised version of) the de Beers cartel, and terrorizes companies with the threat of using the moon to advertise for competitors. He is, in short, not afraid to use questionable means to achieve a worthwhile higher end, and does not — Musk haters take note! — recoil from actual fraud.

Heinlein didn’t provide for live broadcasting of his imagined lunar mission, which is almost an afterthought in his Great Man business yarn. TV cameras were, like computers, one of his blind spots. But if he had thought to make Harriman the owner of a fancy-sportscar manufacturing concern, and if he had thought to have Harriman put a car in solar (trans-Martian!) orbit as one of his publicity stunts, that would have been there in “The Man Who Sold The Moon.” Selling the moon is just what Musk is doing. Except the moon is a tad worked-over as a piece of intangible property, so we get Mars instead.

Entrepreneurs beyond the atmosphere

Doug Bandow reacts to Donald Trump’s executive order that begins to clear the way for private enterprise in space:

Taken by Apollo 8 crewmember Bill Anders on December 24, 1968, at mission time 075:49:07 (16:40 UTC), while in orbit around the Moon, showing the Earth rising above the lunar horizon.

Despite the current chaos caused by the coronavirus, Washington still must consider the future. Which explains the president’s new executive order that would allow private resource development on the moon and asteroids. It clearly rejects the “common heritage of mankind” rhetoric deployed by the United Nations on behalf of the Law of the Sea Treaty, which four decades ago created a special UN body to seize control of seabed resources.

The Future of Space Exploration

The EO issued earlier this month explained that

    Successful long-term exploration and scientific discovery of the Moon, Mars, and other celestial bodies will require partnership with commercial entities to recover and use resources, including water and certain minerals, in outer space.

The measure began the process of revising an uncertain legal regime which currently discourages private sector development.

The administration pointed to the 1979 Agreement Governing the Activities of States on the Moon and Other Celestial Bodies (known as the Moon treaty) and the 1967 Treaty on Principles Governing the Activities of State in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies (typically called the Outer Space Treaty). Neither is friendly to entrepreneurs or explorers with a commercial bent.

In response, the president announced that

    Americans should have the right to engage in commercial exploration, recovery, and use of resources in outer space, consistent with applicable law. Outer space is a legally and physically unique domain of human activity, and the United States does not view it as a global commons. Accordingly, it shall be the policy of the United States to encourage international support for the public and private recovery and use of resources in outer space, consistent with applicable law.

Space is a Long-Term Prospect

The document’s main directive is for the Secretary of State, in cooperation with other agencies, to “take all appropriate actions to encourage international support for the public and private recovery and use of resources in outer space.” The secretary is to “negotiate joint statements and bilateral and multilateral arrangements with foreign states regarding safe and sustainable operations for the public and private recovery and use of space resources.”

Obviously, the administration’s attention is directed elsewhere at the moment. However, the potential benefits of turning to space are significant. The value of scientific research is obvious and continues to drive government agencies such as NASA. Launch services and space tourism have caught the interest of private operators. Such activities offer fewer legal and practical difficulties than attempting to establish some sort of long-term presence in the great beyond.

More complex development of space is a longer-term prospect. However, that makes it even more imperative to encourage innovation by creating institutions and incentives that encourage responsible development of what truly is the “final frontier.”

The United States was losing the space race. A number of unfortunate missteps and mistakes had hindered their progress. But the United States had also structured its space program entirely differently from the USSR. Instead of being helmed by the military, the National Aeronautics & Space Administration was created by Eisenhower with an emphasis on exploration and research. And in the end, the later but more advanced satellites will collect the data required a dream firmly placed in the American consciousness by JFK. A dream to place a man on the moon.

50th anniversary

Astronaut Buzz Aldrin, lunar module pilot, stands on the surface of the moon near the leg of the lunar module, Eagle, during the Apollo 11 moonwalk. Astronaut Neil Armstrong, mission commander, took this photograph with a 70mm lunar surface camera. While Armstrong and Aldrin descended in the lunar module to explore the Sea of Tranquility, astronaut Michael Collins, command module pilot, remained in lunar orbit with the Command and Service Module, Columbia. *This is the actual photograph as exposed on the moon by Armstrong. He held the camera slightly rotated so that the camera frame did not include the top of Aldrin’s portable life support system (“backpack”). A communications antenna mounted on top of the backpack is also cut off in this picture. When the image was released to the public, it was rotated clockwise to restore the astronaut to vertical for a more harmonious composition, and a black area was added above his head to recreate the missing black lunar “sky”. The edited version is the one most commonly reproduced and known to the public, but the original version, above, is the authentic exposure.

“… what’s happening now is even better than Apollo”

Filed under: Space, Technology, USA — Tags: , , , , , — Nicholas @ 05:00

At Popular Mechanics, Joe Pappalardo reminds us that the 50th anniversary of the Apollo 11 lunar landing is coming up next month, but that current developments in space are worth celebrating too:

Astronaut Buzz Aldrin, lunar module pilot, stands on the surface of the moon near the leg of the lunar module, Eagle, during the Apollo 11 moonwalk. Astronaut Neil Armstrong, mission commander, took this photograph with a 70mm lunar surface camera. While Armstrong and Aldrin descended in the lunar module to explore the Sea of Tranquility, astronaut Michael Collins, command module pilot, remained in lunar orbit with the Command and Service Module, Columbia.

Apollo was born of Cold War desperation: a political exercise that paid enormous scientific and technological dividends. After the launch of Sputnik in 1957, it became vital to beat the Soviet Union to the Moon, a geopolitical urge that created an enormous budgetary effort.

The problem with politically motivated — well, anything — is that the faucet of support can be closed just as quickly as it opened. It happened to Apollo, as follow on missions were cancelled and the focus shifted to a reusable craft to service low-earth orbit. This pattern of shifting space priorities and strategies whipsawed NASA, most noticeably when the Obama administration’s cancellation of the Bush-era Constellation moon program in 2010.

But multiple private companies pursuing their niches in space have an obvious redundancy. While companies may rise and fall, the very nature of a commercial effort isn’t as dependent on government funding. If it’s worth doing, especially if it makes money, space industry will endure political shifts. The objectives of a well-run company do not change that much every four years.

That leaves today’s NASA with a choice: Do it themselves and control everything (the traditional way), or fund private companies to develop the tech the agency needs and then allow them to sell their services to any nation, company, or individual (the new way). With those services on the open market, NASA would be one of many customers for a new U.S.-based space economy.

This debate is boiling over right now. The ongoing effort to return to the moon, called Artemis (after Apollo’s sister), is becoming a lesson in the advantages of the commercial model.

[…]

If only investment guaranteed results. For those who miss bloated, government-run spaceflight, there is already a NASA spacecraft mired in the old ways of thinking. The feds have sunk a lot of money into the Space Launch System, a mega-rocket built to NASA specs for deep space missions. It was supposed to fly in 2017, but we’ll be lucky to see a first flight in 2020 — and it busted the $9.7 billion estimated budget, now costing about $12 billion.

But something happened during these SLS delays: the commercial space industry started delivering on its promises. Most visibly, private firms have been delivering supplies to the International Space Station for years and (hopefully soon) will ferry astronauts as well. Blue Origin and SpaceX has started development of crewed spacecraft able to reach to the moon and Mars. Elon Musk even sold a moon trip to a Japanese billionaire.

Back to the Moon in 2019?

Filed under: Space, USA — Tags: , , , , — Nicholas @ 04:00

Charles Stross thinks a US circumlunar expedition is on the cards for just two years ahead, and he might well be right:

If Donald Trump is still president, US astronauts will return to circumlunar space around July 16th, 2019 …

That’s the 50th anniversary of the launch of Apollo 11. It’s also 6-12 months on from the projected date of Musk’s translunar tourist trip on a Falcon Heavy.

I expect Falcon Heavy to be delayed a few months, minimum, because no new launch vehicle ever flies on time, especially a crew-rated one, but it’s currently due to fly around December this year for the first time, with a vehicle currently undergoing integration at Cape Canaveral and commercial orders for subsequent flights. It’s rather hard to describe it as vaporware at this point. The same goes for the Dragon 2 crewed capsule; it’s due for a first uncrewed orbital flight test in March 2018, and a crewed orbital test flight later in 2018.

[…]

I’m making this a prediction, however, because the POTUS factor.

July 2019 lies within the term in office of Donald Trump (or Mike Pence, depending whether impeachment/removal has happened first then). Trump is nothing if not an egomaniac, and offering him the opportunity to make a historic phone call to lunar orbit in front of the TV cameras is a guaranteed ego-stroke. Trump is of an age to have young-adult memories of Apollo and I can’t see the idea not appealing to him if he can take credit for it.

So I’m betting that this is how Musk will fund development of his lunar-orbit capability.

(Terms and conditions: prediction invalid in event of nuclear war, global environmental or economic collapse, Trump and Pence both being impeached, or a Dragon 2 capsule exploding in flight, because any of these things might impact the launch schedule.)

Note: Charles is quite a fan of the impeachment scenario, if you hadn’t picked that up from context. The fact that he’s very much not a Trump fan actually makes his prediction that much more striking: he has no interest or desire to see Trump get a propaganda coup to end his term in office.

NASA swings for the Moon … and misses

Filed under: Space, USA — Tags: , , — Nicholas @ 04:00

Robert Zubrin is not a fan of NASA’s recent announcement of a planned lunar orbital station as its next major goal, calling it “NASA’s worst plan yet”:

At the recent Space Foundation conference held in Colorado Springs, NASA revealed its new plan for human space exploration, superseding the absurd Asteroid Retrieval Mission (ARM) championed by the Obama administration. Amazingly, the space agency has managed to come up with an even dumber idea.

In the early months of the Trump administration, some lunar advocates spread the rumor that the new president would seek a return to the Moon within his first four years, thereby dramatically making America great again in space. That is not the plan.

Nor is the plan to send humans to Mars within eight years, something that I think we could achieve. Nor is it to send human missions to explore near-Earth asteroids, as then President Obama suggested in 2010, nor is it even to send humans to a piece of an asteroid brought back from deep space to lunar orbit for study, as called for in the ARM.

No, instead NASA is proposing to build a space station in lunar orbit. This proposal is notable for requiring a large budget to create an object with no utility whatsoever.

We do not need a lunar-orbiting station to go to the Moon. We do not need such a station to go to Mars. We do not need it to go to near-Earth asteroids. We do not need it to go anywhere. Nor can we accomplish anything in such a station that we cannot do in the Earth-orbiting International Space Station, except to expose human subjects to irradiation – a form of medical research for which a number of Nazi doctors were hanged at Nuremberg.

If the goal is to build a Moon base, it should be built on the surface of the Moon. That is where the science is, that is where the shielding material is, and that is where the resources to make propellant and other useful things are to be found. The best place to build it would be at one of the poles, because there are spots at both of the Moon’s poles where sunlight is accessible all the time, as well as permanently shadowed craters where water ice has accumulated. Such ice could be electrolyzed to make hydrogen-oxygen rocket propellant, to fuel both Earth-return vehicles as well as ballistic hoppers that would provide the base’s crew with exploratory access to most of the rest of the Moon. Other places on the Moon might also work as the base’s location, because while there is no water in nonpolar latitudes, there is iron oxide. This can be reduced to produce iron and oxygen, with the latter composing 75 percent or more of the most advantageous propellant combinations.
