Apollo at 50. Plus updates from space


I was 18 years old, had just survived my frosh year at Caltech, envious of those I heard were heading to a rock concert back east while I worked the unner hauling a radio astronomer's tapes on and off an IBM360-75... and I recall watching Walter Cronkite interview Robert Heinlein and Ray Bradbury, with all of them in tears of joy. And seeing Arthur C. Clarke and Isaac Asimov hold forth on other networks, as a nation and world came to realize that Earth is not enough. The rest of the universe is palpable and real; you can step on it! And a literature that looks forward just might have some relevance.

Apollo 12 would be the stunning display of utter competence and Apollo 8 had just given us one of two great artworks of the 20th Century, changing human hearts without needing a word of persuasion. But it was Neil and Buzz and Mike and the tens of thousands who got them there, and tens of millions who paid for it, and a billion or so watching - thrilled - who got a boost to our inner confidence, at a time when we would need it most.

Draw from it now! That competence and confidence matters. Don't let enemies undermine -- or worse, hijack -- that pride in a scientific, pragmatic, progress-oriented and change-willing civilization. Those of our neighbors who are helping to wage war on facts... remind them that those inconvenient truths help us to revise and to learn and to become greater than we were.

Organoids in space: Will human cells differentiate and proliferate and organize themselves properly - if development takes place in micro-gravity? Finding out is the aim of a human-brains-in-a-dish experiment created by UCSD researchers and about to be shipped up to the Space Station. I am tangentially part of the team led by Alysson R. Muotri, PhD, in cooperation with UCSD's Arthur C. Clarke Center for Human Imagination.

After a brief embargo, I can now link you to the announcement of new phase III grants by NASA’s Innovative and Advanced Concepts program. (I was in DC last month as a member of NIAC’s External Council.) Phase One offers small seed grants to explore an idea that’s just this side of science fiction, and sometimes beyond that line. Phase Two allows the best-demonstrated Phase One concepts to develop more tech/sci readiness across 2 years. Phase Three is brand new.  Substantial funding to demonstrate real feasibility for a space mission. The first two P3 grants can now be viewed here. Both involve the quest to access lunar and asteroidal resources.

At that meeting in DC, we discussed NIAC’s difficulty in attracting brilliantly conceptual proposals from underrepresented groups or categories. Some of the finest ideas have been in areas like biology, life support or habitation… and a number of these came from just Lynn Rothschild and her students!, so we know there are great innovators in those fields. We just need to get the word out, better. Your suggestions for groups or conferences, startups or companies that might have a stunning notion potentially applicable to spaceflight would be welcome, below. (Under-represtnted groups welcome.) Better yet, share with those folks links to the NIAC information pages!

And if NIAC’s brash innovativeness is way too-sane for you, then try this gonzo-paranoid techno tall tale about high ISP rocketry by my colleague Charles Stross. It's like if NIAC got really, really mad and turned from mild-mannered Bruce Banner into the Hulk. 

Oh, and here are some images from my June talk to a packed auditorium at Goddard NASA Spaceflight Center. There I offered a trio of slides that portray distinctly why  readily accessible riches are available on asteroids, but only one kind of any likely near-term value exists on the moon: lunar polar ice. (And even water will likely be better accessed from certain kinds of asteroids.)

Metals, in particular, are unlikely to be a “lunar resource.” Want to know where to find them out there? See how NASA has given go-ahead to the Psyche Mission! “While most asteroids are rocky or icy bodies, scientists think Psyche is composed mostly of iron and nickel, similar to Earth's core. They wonder whether Psyche could be the nickel-iron heart, or exposed core, of an early planet maybe as large as Mars that lost its rocky outer layers through violent collisions billions of years ago.” And a lot more than nickel-iron.

== News from the Solar System ==

Partly inspired by earlier NIAC grants, NASA will fly a billion-dollar quadcopter to Titan, Saturn’s methane-rich moon. Acetylene-butane co-crystals might form rings around Titan's lakes as liquid hydrocarbons evaporate and the minerals drop out—in the same way that salts can form crusts on the shores of Earth's lakes and seas. Huh, I had envisioned the Titanian shore-dwellers mad of wax. Shows what I know.

The Deep Space Atomic Clock experiment will test miniaturization of super accurate time keeping in space, so future missions (mars & beyond) can self-navigate. 

Cool. NASA’s Osiris-Rex spacecraft has been orbit-spiraling close to asteroid Bennu. See images  from just 690 meters away. The spacecraft is designed to reach out to Bennu, snag a sample of surface material and bring it back to Earth in 2023. The recent impressive Japanese sampler mission to another asteroid shows who we should be partnering with, to do things out there that none of the Apollo-wannabe lunar dust-tourists can dream of. Possibly accessing the riches that would enable greatness while paying for a restored Earth.

Speaking of which. Even stony asteroids are moist – testimony from samples returned by Japan’s first (of two) Hayabusa probes, supporting the notion that other kinds – like carbonaceous C-type or extinct comets – will likely be very rich in the stuff of life (and of rocket fuel).

While asteroids offer the greatest (vast) trove of available wealth to a nascent interplanetary civilization, there are rocks along the path. Both Planetary Resources (PI) and Deep Space Industries have scaled back their immediate ambitions to access metals like Platinum, and PI’s assets have been acquired by one of the founders of Etherium. (A thought provoker, that news.)

Meanwhile, Joel Sercel’s TransAstra Corp. Keeps winning grants to pursue the nearer term profitable resource, water, on both asteroids and the lunar poles.  He has competition there! The Chinese have declared lunar polar ice to be their goal, as has George Sowers of the Colorado School of Mines and even – officially, at least – The current U.S. administration.

== Politics of space ==

SpaceX has successfully deployed sixty production versions of the Starlink Satellite. They are targeting 360 through the next six months, aiming at a lot of revenue for service to North America, Europe and Asia, by reducing latency in financial trading communication.

That obscure but lucrative revenue source is crucial since it will flow almost immediately once the constellations prove reliable. In fact, it could be why folks still lend Elon money for Tesla, because (yet again) one of his businesses will be able to pay off debt for another at a critical moment. It also would give Starlink time to build its more general internet access business.

Two factors though. First, Bernie Sanders has raised the prospect of a potential transaction tax on financial trades. In fact, it is a very important reform that could save all of us from genuine dangers from the worst kinds of AI. But fortunately for Elon, it won’t happen for at least two years. By then, Starlink will have other sources of revenue.

The other factor is China. The arrival of these new low-orbit internet constellations will mean citizens of the Central Kingdom may have another chance at a free infosphere. Daunted by this prospect, at times the PRC has threatened to “shoot down” such constellations.  An impractical threat and a sign of desperation. So, will they seek to make a deal with Elon Musk and Jeff Bezos and others?  Or will they try to get control over that situation by going over their heads, through their friends in American high places?

Meanwhile the current head of Roscosmos – the Russian Space Agency – has laid down a vision for moon landings by 2030, by creating a launch system more powerful than NASA’s in-development SLS. This article, while conveying his slides, is justifiably skeptical. More likely would be a Russia-China partnership. Perhaps and/or India. I hope not snaring in ESA, Japan, or the U.S., who have better things to do, elsewhere. Best case? Commercial tourist junkets leave them in a cloud of mood dust.

NASA is giving the public an opportunity to send their names — stenciled on chips — to the Red Planet with NASA's Mars 2020 rover. And sure, I recommend you sign on! I give odds of a bazillion to one against anything bizarre happening as a result (as in my short story “Mars Opposition,” published in Insistence of Vision.
