Space Colonization Options (Orbiting Stations, planets/moons)

...or the other smaller Trojan 2010 TK7 or NEOs such as 3753 Cruithne, 54509 YORP, (85770) 1998 UP1, 2002 AA29 and 2009 BD that are in resonant orbits with the Earth. Devising the robotic technology to move and exploit these objects would also allow us to clean up and recycle the artificial debris orbiting the Earth.

Not a rubble pile…maybe a firm foundation for a powersat.

would have been a good test for the asteroid retrieval/redirect mission too, had Artemis not happened

 

[XCV330]

was looking at some recent survey
And saw this: https://www.spacereference.org/asteroid/2021-ph27
Has an interesting orbital resonance, and it never crosses Earth's orbit, always inside. Closest approach .23AU.
It is not high on the list of visitation targets, but it's also more substantial, not one of those 10 meter boulders that get top listings.
What's more interesting, I think is the crossing of Venus and mercury orbits. Manage it right and you could have a cycler-setup for occasional visitation and otherwise automated observatories to make regular observations of Mercury, Sun and Venus on close approaches.

This is great for fuel tanks—and resists oxidation to boot!

—and 138 times stronger than steel

Frustration incorporated: How mismatched geometries can enhance material strength and toughness

Anyone who's ever tried tiling a floor, a backsplash or even an arts-and-crafts project probably knows the emotional frustration of working with pieces whose shapes don't perfectly complement each other. It turns out, though, that some creatures may actually rely on similar mismatches to create...

How do bird nests stay together? Researchers unravel entanglement between stiff, straight rods

The concept of constructing a self-supporting structure made of rods—without the use of nails, ropes, or glue—dates back to Leonardo da Vinci. In the Codex Atlanticus, da Vinci illustrated a design for a self-supporting bridge across a river, which can be easily demonstrated using toothpicks...
