To The Moon

By Jan S. Gephardt

As I write this, the Artemis 1 Mission is still “go for launch” next Monday, Aug. 29, 2022. A lot of us are excited about the prospect of a new Moon program. But other voices, from both left and right, question whether we should go back to the Moon at all. Indeed, from the very beginning there have been questions about the priority we should give to our reach into Space.

We haven’t been to the Moon since the last Apollo mission in 1972. A full 50 years. Half a century. Dating myself, here, for the sake of scale: that was the year I graduated from high school. I’m retirement-age now, so that’s a working lifetime ago.

Why not? We’ve launched other missions – why not go back to the Moon till now? In my research, I’ve discovered several reasons.


I think we're going to the moon because it's in the nature of the human being to face challenges. It's by the nature of his deep inner soul... we're required to do these things just as salmon swim upstream. – Neil Armstrong
That was then. Why haven’t we gone back for all these years? (Famous Quotes 123).

 

Politics

Consider the political landscape in the United States between 1972 and 2022. Control of the House, Senate, and White House has seesawed back and forth between Republicans and Democrats rather frequently, after two long periods of Democratic Party rule during the Roosevelt-Truman years and again during 1960s and the Kennedy-Johnson administrations.

This meant that each administration and Congressional majority got to make up their own rules. They felt free to set, re-set, abandon or continue the policies of their predecessors. As a result, there were never enduring, universally-established ideas about where, how, and even if, we might boldly go anywhere. Including to the Moon.

The last Apollo missions happened during the Nixon Administration, but while Nixon wasn’t exactly against space expansion, he was much more bullish on the idea of making space more affordable and accessible. The Space Shuttle project had its origins in the Nixon White House.


“Before another century is done it will be hard for people to imagine a time when humanity was confined to one world, and it will seem to them incredible that there was ever anybody who doubted the value of space and wanted to turn his or her back on the Universe.” — Isaac Asimov
Isaac would undoubtedly have been disappointed to know it would take us 50 years to refocus on the Moon. (Quotefancy).

 

Focus, Refocus, and Lack of Focus

Space programs take a long time to develop, and they require a lot of money. People in power haven’t always seen it as a high spending priority, especially in times of economic difficulty. Many early programs ran into cost overruns of the sort that saw Skylab B mothballed in the mid-70s, about the same time the Soviets canceled the Almaz (space platform) project, possibly for similar issues.

In the latter 1970s the Space Shuttle program remained in the development stages, but continued to move forward. The Ford and Carter administrations were preoccupied by inflation, an energy crisis, foreign threats, and social upheaval. Ford greenlit the Office of Science and Technology Policy (OSTP). Carter emphasized the need to self-defense in space, but didn’t take the idea very far. You’ll notice that none of these ideas got us anywhere closer to the Moon.


“All civilizations become either spacefaring or extinct.” — Carl Sagan
Sagan’s sample-size did nothing to lend power to his words at the time. He died in 1996, at a time when NASA’s Space Shuttle fleet had begun to show its age and limitations, but new space initiatives weren’t in fashion. (Quotefancy).

 

Space-Based Defense

Ronald Reagan took that space-based defense idea and majored on it. He proposed a massive Strategic Defense Initiative (SDI). But vocal observers complained it was unrealistic for the technology of the period. They nicknamed it “Star Wars” and painted it as over-priced science-fictional wish-fulfillment. At the time, they weren’t entirely wrong, although the idea of space-based defense both predated, and ultimately outlived Reagan’s idea.

George H.W. Bush was a space-development booster. On the 20th anniversary of the our first Moon landing, he announced the Space Exploration Initiative (SEI), which included a space station called Freedom – but no plan to return to the Moon anytime soon. Congress couldn’t get past the idea of its $500 billion price tag, however. Not even if the spending was spread across 20-30 years.

Bill Clinton’s administration never brought “Freedom” to fruition, but did start construction on the International Space Station. He focused more interest on exploring the universe, and kept the door open on space-based weapons. Especially in his second term, however, divisions in the United States grew more extreme. The Republican-led Congress was unwilling to work with him on initiatives of most any sort.


“It is difficult to understand the universe if you only study one planet.” — Miyamoto Musashi
The Clinton Administration created the National Science and Technology Council. They backed exploration and the ISS, but had little interest in a return to the Moon. (Quotefancy).

 

Advance and Retreat

George W. Bush reshaped NASA policy yet again, refocusing on space exploration (Vision for Space Exploration, 2004). He reintroduced plans to return to the Moon (by 2020), retire the Space Shuttle program, and start preparations to send humans to Mars. But Bush became much more heavily focused on waging two wars that did not produce predicted easy victories, and the onset of the Great Recession at the end of his term.

His successor Barack Obama had little time or energy for space, and certainly not for the Moon. Not in the depths of the Great Recession. His political capital went for economic fixes and the ACA. Faced in his second term with an oppositional, Republican-led Congress, few initiatives prospered. But he did use his executive power – to kill most of “W’s” space initiatives, including a trip to the Moon.

Instead, he opened the door for more private investment in space and a focus on commercially-exploitable asteroids and Mars. SpaceX, Blue Origin, and other initiatives began their dramatic rise.


“In the coming era of manned space exploration by the private sector, market forces will spur development and yield new, low-cost space technologies. If the history of private aviation is any guide, private development efforts will be safer, too.” — Burt Rutan
The Clinton Administration created the National Science and Technology Council. They backed exploration and the ISS, but had little interest in a return to the Moon. (Quotefancy).

 

Taking the High Ground

I’ll refer you to my sister’s excellent essay on the Space Force for a look at the most recent iterations on the United States’ focus on space-based defenses. The Trump Administration further encouraged private space enterprise. They resurrected the National Space Council (continued under Biden and currently chaired by Vice President Kamala Harris). And they shifted the country’s efforts from the Obama-era focus on Mars back to the Moon.

The Biden Administration embraced and continued the internationally-supported Artemis project, which will (we hope) launch Artemis 1 on Monday. The long-delayed return to the Moon has finally begun in earnest.

Riding atop the Space Launch System (survivor of the “W” Bush-era Constellation project), the Orion spacecraft won’t carry humans this time (“Captain Moonikin Campos,” “Helga,” and “Zohar,” all varied types of sensor-equipped “manikins,” will ride in their place, along with NASA mascot Snoopy and ESA mascot Shaun the Sheep). Nor will it land on the Moon. but it will deploy CubeSats and orbit the Moon.


“If God wanted man to become a spacefaring species, he would have given man a moon.” — Krafft Arnold Ehricke
Looks as if the Artemis Project might actually get us there after all. (Quotefancy).

 

Artemis 1, 2, 3, and Beyond

Monday’s launch of Artemis 1 is an essential test of equipment and systems. If all goes well, in mid-October NASA will retrieve it from the Pacific Ocean. At that point, teams of scientists will start feverishly poring over its data. They must apply everything they can learn from Artemis 1, to ensure the safety of the human crew on Artemis 2.

Artemis 2 is currently planned for a May 2024 launch date. It, too, will orbit the Moon, but won’t land. The crew has a whole laundry list of systems checks to perform, both in Earth orbit and during the lunar flyby. The Artemis 2 crew hasn’t yet been named, but they’ll all be North Americans: three from the USA, and one from Canada. Whoever they turn out to be, the latter will be the first Canadian ever to travel beyond low Earth orbit.

We’ll get to Artemis 3 sometime in 2025 . . . we hope. There have been numerous delays already. This first crewed Moon landing of the Artemis Project (first humans on the lunar surface since 1972) also will see the first use of the SpaceX-built Starship HLS. If all goes well, this will be a true return to the Moon.

Artemis 1 through 3 are the beginning, not an end-point. Artemis 4 starts building another international effort:  a space station called Lunar Gateway, designed to orbit the Moon. And you can guess from the name where things are headed from there. It all starts with a return to the Moon.


“The Moon is the first milestone on the road to the stars.” — Arthur C. Clarke
Sir Arthur might be right, after all. (Quotefancy).

Challenging assumptions in science fiction: 3. Worth their weight in diamonds

This is the third in a series of posts that question some of the classic tropes in science fiction. This series was inspired by observations made while reading Leviathan Wakes by James S. A. Corey.

The book is a really wonderful space opera, first in The Expanse series, which later inspired the creation of the SyFy Channel show, The Expanse, in its third season as I write this. But it does seem to accept unexamined some of science fiction's time-honored (and, in my mind, outmoded) tropes.

In particular, my comments center upon Ceres Station, its population, and its governance, as portrayed in the book. I compiled a short list of outstanding reasons NOT to live on Ceres:
  • Human life is apparently cheap, and easily squandered with no penalty
  • Freedom of speech is nonexistent, and so is freedom of the Fourth Estate
  • The nutritional base is crap. Seriously? Fungi and fermentation was all they could come up with? Readers of this blog don't need to guess what I think of this idea.
  • Misogyny is alive and well, but mental health care is not.
Last week I took issue with the idea that there would be abundant, expendable excess humanity available in the extrapolated setting and time span.

The primary reasons why humans won't be that abundant are the difficulty of achieving a viable pregnancy in most space (or space-adjacent) environments, and the lowered rates of childbearing among well-educated women who can control their fertility, a reality we already have seen played out in developed nations for several decades.

Today, I'd like to look at the reasons why the humans who do get there won't be expendable at all. ASIDE from the human rights angle, which ought to be the FOUNDATION of any discussion about the "expendability" of human lives, if we’re not going to have lots of excess babies in space, then Earth is probably exporting the vast majority of the people who live in space.

Every human being who is technically educated to the point of being employable Out There, then hauled up out of the gravity well is going to be an extremely valuable commodity. 

"Hauled up out of the gravity well" alone gives you one reason. In 2009, Michio Kaku explained the cost of transporting someone to Mars this way, in a Forbes article: "imagine your body made of diamonds."

The XKCD Web Comic gives us ALL the gravity wells (in the solar system, that is)!

Even now, it doesn't cost as much to put a human in orbit as it did in the early days of the Space Race, and that cost will inevitably continue to go down. But I guarantee you it'll never be so cheap and easy that "anybody can do it." 

Nor should "anybody" do it. Space is dangerous. Learning how to survive there takes a lot of training and highly specialized (not cheap) equipment. Which brings me to my next point: the "technically educated to the point of being employable" part.

If humans are neither able nor inclined to breed like rabbits in the tunnels of Ceres, that means in space most of the "grunt labor"--and more of the advanced processes than you might imagine--will be done the way more and more of it already IS, here on Earth: by robots. Robotic manufacturing processes are already essential to the current aerospace industry, and this trend won't go away. I examined this and related automation issues in a series of posts about the automation of labor that started last March. 


Who will manage, troubleshoot, and integrate those robots? That's the role for highly technically skilled and trained humans. Humans with master's degrees and doctors' degrees, sure--but also highly skilled technicians, to keep everything running as it should. We're already experiencing a critical shortage of skilled labor, and the push into space will only add competition to entice workers in this job niche.

Typically, competition for workers means good salaries, signing bonuses, enticements, and perks added to sweeten the offer. If you want a model for what the workforce of the future will look like, look at Silicon Valley and the current aerospace industry--not the coal mines and textile mills of yesteryear.

Skilled workers, designers, and more are needed to put Spacex rockets into orbit--and the need for such teams will only grow as human expand their enterprises into space.
Moreover, companies are going to have to treat their employees with respect, or those intelligent, educated people will find ways to organize for change, mutiny, or jump ship to sign on with a competitor. How has science fiction not figured this out yet?
