MINING THE ASTEROIDS Part 14: Another Player “Believes”!

Initially, I started this series because of the 2021 World Science Fiction Convention, DisCON which I WOULD have been attending in person if I felt safe enough to do so in person AND it hadn’t been changed to the week before the Christmas Holidays…HOWEVER, as time passed, I knew that this was a subject I was going to explore because it interests me…

“We [at Karman+] want to mine space resources from near-Earth asteroids to provide abundant, sustainable energy and resources in space and for Earth.”

Whew! Bold words!

Karman+ is the most recent company to throw its helmet into the hype-filled sea of speculative asteroid mining. They DO note that asteroid mining has “lived at the intersection of scientific research and popular culture for decades, with as many academic papers published as there are books, TV shows and movies about it.”

That being said, everyone knows that the ULTIMATE reason to start mining the asteroids is because what metals that are left on Earth have been mined practically to the bare rock walls. And even MORE ultimately, the mining concerns are facing the possibility of the total depletion of their cash cows.

I live in Minnesota. During World War II, “Minnesota nearly depleted its immense supply of high-grade iron ore to help the Allies win World War II, providing much of the crucial raw material behind America's tanks, warships, guns and ammunition…”

But how MUCH is “much”? “SEVENTY percent of the iron ore that America devoted to the war came from Minnesota…333 million tons, according to Pam Brunfelt, a retired Vermilion Community College faculty member and historian.” She added, “without the Iron Range, we would not have won the war…[Today], our resources-driven growth faces a massive existential challenge, with climate change, ecosystem degradation and resource depletion demanding a complete reset. Humanity needs to shift global transportation, manufacturing, construction and energy onto a sustainable path.”

There are a growing number of companies who are talking a BIG TALK about mining asteroids; just as there are a number of individuals who live in total doubt that something as ridiculous as “mining asteroids” will EVER take place. From these early, serious attempts to realize, these modern day space pirates are intent on sinking any serious discussion or intention to realize any alternatives to mining in space by insisting that Earth is the ONLY PLACE WE WILL EVER GET THE METALS WE NEED TO CONTINUE TO BUILD OUR SOCIETY. (see: MINING THE ASTEROIDS The Final Post: Maybe THESE Are The REAL Space Pirates? ~ Stupefying Stories Magazine)

Fortunately, there’s another new company willing to do more than talk. The “Karman+” and logo come from the concept of the Kármán line, established in the 1960’s, “a proposed conventional boundary between Earth's atmosphere and outer space set by the international record-keeping body FAI (Fédération Aéronautique Internationale) at an altitude of 100 kilometers (also: 62 miles or 330,000 feet) above sea level.”

There’s no measurable change in the characteristics of the atmosphere across it, but it IS important for legal and regulatory purposes. Anything flying above it is considered a spacecraft; anything below it is just an airplane, no matter how fancy.

Those two types of vessels are subject to different jurisdictions and legislations. It IS a lot higher than we can reach with a regular jet or a high altitude balloon. But it’s also the point at which a satellite in orbit around Earth will inevitably fall out of the sky.

Karman+ believes in something called “the Regolith Age, powered by abundant space resources, is an inevitability that we can accelerate.” Because they don’t offer ANY kind of definition, I’m somewhat suspicious of their mission…though I think I can parse it reasonably well:

Regolith: “regolith, a region of loose unconsolidated rock and dust that sits atop a layer of bedrock and serves as a source of other geologic resources, such as aluminum, iron, clays, diamonds, and rare earth elements. It also appears on the surfaces of the Moon, other planets, and asteroids. The word is the Greek term for “blanket rock.” So, we expect to not actually DIG into asteroids, but merely swoop in and scoop up the regolith and either refine it in orbital facilities and what? Drop down slugs of iron, steel, gold, frankincense, and myrrh?

Either that or ship raw regolith back to the surface in…space shuttles? Heat-shielded “drop capsules”? [NOW THERE’S AN IDEA! Pack a drop capsule full of unrefined regolith. Send it on a one-way fall into the ocean with some kind of floater ring. Provide a vent in the top of the dropper, and voila, the capsule will be full of partially smelted metal even before Humans get their hands on it.] But wouldn’t it kind of be bad if one of these dropper companies sent a ship down with regolith that shows a high concentration of gold, platinum, or other desirable metals – and some mean, old fashioned PIRATE pirates grabbed it and make off with it?]

Hmmm…Karman+ points out that there have been baby steps made in the returning of samples to our surface from other bodies: from the various rocks returned on the original Apollo Lunar landings (“Between 1969 and 1972 six Apollo missions brought back 382 kilograms (842 pounds) of lunar rocks, core samples, pebbles, sand and dust from the lunar surface. The six space flights returned 2200 separate samples from six different exploration sites on the Moon. In addition, three automated Soviet spacecraft returned important samples totaling 300 grams (approximately 3/4 pound) from three other lunar sites.” (https://curator.jsc.nasa.gov/lunar/)

“That last step has been advanced through the Hayabusa and Hayabusa2 missions run by JAXA, both of which also returned sample material back to earth. This will be expanded in the coming years with the NASA-run OSIRIS-REx mission, taking our total count of asteroid sample return missions to 3. As well, AstroForge did some experiments on asteroid mining earlier this year. (https://faithandsciencefiction.blogspot.com/2023/05/mining-asteroids-part-13-new-kid-in.html)

So, despite the nay-sayers, doom-layers, and plain haters, the possibility of mining the asteroids is moving forward, albeit slowly. Consider, however, how many years it took between Goddard’s first rocket experiments and Apollo 11’s historic landing on the Moon – forty-three years between his first liquid fuel rocket launch, and “One small step for man; one giant leap for mankind.”

Since then, we haven’t stopped and the exploration of space has included virtually every nation with launch capability – or the wherewithal to buy a place in space.

I think our “negativity experts” have chosen to stand in stubborn surety on the WRONG side of Human history.
