I'd say this is @realfr0s7's best work: O'Neill cylinders many kilometers long, housing millions of people, positioned around Earth and elsewhere.

More views of the nuclear thermal rocket stage that Rene Aigner designed for USNC. The shape of that propellant tank is still a mystery to me. Perhaps it is disk shaped to serve as radiation shield for the payload?

Hmmm...

"[I]t is [...] known that a so-called Dyson sphere encompassing a single star would be unstable due to Newton's shell theorem. A surprising finding is reported here that both a ring and a sphere (shell) can be stable in the restricted three-body problem."

A variant of the Firefly interstellar probe, driven by an immensely powerful D-D fusion rocket. Most of the craft's length is dedicated to radiators, with transparent debris shields and propellant tanks up front.

Phobos and its smaller neighbouring moon, Deimos – both discovered in 1877 – are two of the most perplexing worlds in the solar system. “They’re the only objects at this stage, in the solar system, for which we have pretty much no idea what they are,” says Pascal Lee at the SETI Institute in California. “We know what other moons are. We know asteroids and comets. Phobos and Deimos? No idea.”

One of the 1st steps to #worldbuilding a #space #ttprgg is to consider what player experiences it's meant to facilitate.

As w/ our core manual, we want to

1) Reimagine existing #scifi thru a #solarpunk lens &
2) Create original stories that can't exist outside of this context. [Thread]

Two years ago, NASA's Curiosity Mars rover captured this feathery iridescent cloud after sunset. The color is created by diffraction effects when sunlight is scattered by small CO2 particles in the cloud.

A long stretched wispy cloud, almost shaped like a feather glows in the sky of Mars at dusk. The cloud shines in different colors, from blue near the horizon, to a yellowish-green on the other side.

More coverage of obtrusive space advertising, by @Gizmodo. "Astronomers are calling for a global ban on space advertising, in hopes that the issue can be nipped in the bud amid a period of rapid commercialization and privatization in spaceflight."

This is what it looks like when a planet dies.

K2-22b orbits so close to its star that its outer layers are vaporizing, meaning that we can directly study the insides of a world 787 light years away.

Rocky exoplanets that get too close to their star can slowly evaporate, leaving a trail of material in their wake. The JWST observatory measured the compounds vaporizing from planet K2-22b (left). An artist’s illustration of a disintegrating planet shows how light is affected as it passes through the exoplanet’s tail (right).

Robert A. Heinleine wrote about a team landing on the Moon, who, after building a radio shack there, contemplate building some huge vacuum tube amplifiers in-situ too, with all the internals of the tubes laid out in the open; vacuum would be provided by nature for free, so there would be no need for rigid tube enclosures.

Some filtering out of Moon dust might be necessary though 😀

Not to spoil the novel's plot, but Nazis where on the #Moon way earlier than Nazi Musk was even a molecule in this world, according to #Heinlein. They didn't fare well there, either.

So, Musk & Co are now trying a #Mars grift…
