Rocket pioneer Krafft Ehricke:
"If God wanted man to become a spacefaring species, He would have given man a Moon"
Of the major moons, only ours is heavy and distant enough for its manifolds to join the interplanetary highway

This video was presented at the NASA-USGS Offworld Resources Workshop. Every curve in it is a computed trajectory, not an artist’s sketch.
1: Asteroid material arrives at the Rim, about 1.5 million km out, on natural paths into orbits around Sun-Earth L1 and L2.
2: From the Rim, refined material coasts to the Moon on gravity alone (~40 days) and is captured.
3: A few m/s burn puts it on an Earth-Moon cycler, which drops packages onto other orbits along its route.
The Earth-Moon system is threaded with natural routes like these. Find the right ones, and moving material around cislunar space costs tens of meters per second, not kilometers per second.

This is a fantastic video explaining orbital dynamics and the resulting economics, and security considerations of cislunar space. Well worth the 8.5 minutes to watch. youtu.be/kdpOdSMzXTA?is=By6z…
Just what is "CISLUNAR SPACE"? I explain it clearly in this VIDEO:

What if a spacecraft could cycle between Earth and Moon orbits, performing multiple circuits of each, naturally and indefinitely, with zero propulsion?
We’ve discovered a new class of stable, prograde, low-energy cycler orbits that do just that.
Why these orbits matter:
Ballistic → fuel-free
Stable → long-term ready
Near-chaotic → agile with low ΔV
Low-energy → access to Earth/Moon, Lagrange points, Sun–Earth L1/L2, even heliocentric space
At the AAS/AIAA Astrodynamics Specialist Conference in Boston next week, I’ll present on a new family of ballistic Earth-Moon cycler orbits that are stable, prograde, and mission agile—unlike any cyclers in the current literature.
The example below is shown in both the Earth-Moon rotating frame and inertial frame.

🪐 What will it take to build the infrastructure for a thriving space economy?
In the latest episode of the Space Strategy Podcast, Peter Garretson sits down with Steve Kwast, Lt Gen, USAF (Ret.), PhD, Co-Founder and Chairman of SpaceBilt, Inc., to examine the future of cislunar logistics and its implications for commerce, national security, and U.S. strategic competition with China.

Asteroid mining is not only going to make a lot more trillionaires, it's going to make us all rich.
Just like the Industrial Revolution, the Space Revolution will greatly increase standards of living across humanity... yours, mine, everyone's.
Electric light and indoor plumbing were once luxuries. Now they are so universal that we can have them and still think of ourselves as poor. But preindustrial folk would have thought us wealthy beyond measure. What's coming is another paradigm shift.
You may think this is all theoretical.
You may think asteroid mining is an unproven concept. You're wrong. Because you don't know one critical fact.
We're already asteroid mining.
And we've been doing it since the Bronze Age.
All gold we mine on earth, all the copper for wires, the uranium for reactors, all the iron for nails, everything made of heavy metals that you own, or use, or have ever seen... it's all mined from ancient asteroid strikes.
All the native Earth metals sunk to the core when the whole planet was molten. Past our reach.
Do you think there are precious metals, like gold and silver and platinum? Do you think that even common metals, like iron and tin and copper, cost a lot to extract and refine?
Artificial scarcity.
Every piece of metal you have ever seen was sourced from the tiny percentage of asteroids that once hit Earth.
Leave the gravity well, learn to sail the void, and we can loot all the asteroids that haven't.
Imagine that we built all of civilization picking up our raw materials, grain by grain, with tweezers.
Asteroid mining, true asteroid mining, is a shovel. And no, not a hand tool shovel, I mean the shovel attachment on the front of an industrial digger.
That's why SpaceX has trillion dollar plus valuation. And unless we screw things up on Earth, and sabotage them somehow, that valuation is way too low.
Below here, you'll see a different part of the plan. A little company, running out of a little industrial space in the San Fernando Valley, is building humanity the ultimate shopping bag.
They think Mars is a sideshow, you see.
They want to bag up asteroids, just scoop the little ones right up with a great big robot butterfly net, and bring back to high Earth orbit.
Strip them down there, and build.
If you thought data centers in space are wild, wait until you see factories in space. Wait until everything from toasters to CPUs to machine tools are made in high orbit, or on the moon, and the only bits that ever make it to Earth on the finished products.
In space, minerals are cheap. And power is free. And it doesn't cost much of anything to move goods down a gravity well.
You have no idea what's coming.
Neither does SpaceX or Transastra, for that matter. They've got a hold of the tail of the elephant, and they think the Space Revolution is a rope.
I'm a science fiction author. My job is to see the whole elephant.
It's a big fucking elephant.
The secret plan is out! Two great articles today about our plan to capture a small asteroid and bring it into Earth orbit. The concept is part of our New Moon mission, which explores relocating a small near-Earth asteroid into a controlled orbit as the first step toward building industrial infrastructure in space.
Our team has been developing the key technologies for this approach for years, including capture mechanisms to constrain and move small asteroids and orbital debris. Accessing materials already in space could eventually enable a new generation of industries beyond Earth.
If you're interested in the future of space resources, these articles are worth a read.

ICYMI: The next great power competition isn't just on Earth. @afpc’s @GarretsonPeter makes the case in the latest Forum for why space resources — a billion times the energy and a million times the minerals of our planet — are the defining stakes of the 21st century – bit.ly/4dMbTG8
