To assemble the massive SBSP satellites, an equally massive launch vehicle was devised: the Star Raker.
@dsfpspacefl1ght has a write-up on what is probably the most iconic SSTO from NASA.

Did you know it ejected most of its landing gear after take-off?

Fascinating work by Lee Fitzgerald, done to depict the 'Edward Israel' for The Expanse.
Unlike most spacecraft in that setting, it spends long periods in microgravity, so including a spinning habitat ring for artificial gravity made sense.

An orbital ring from 'The Culture' universe by Iain M Banks is struck by a relativistic spaceship.

@AlexJayBrady brings across the violence and destruction of such an event in this impressive #space #art.

The Tupolev-108 'composite bomber'.
A large carrier equipped with 'propjets' cruises at 1000km/h over 6000km, then drops off a plane that makes a supersonic 1000km dash to the target.
Delta wings and significant area ruling were needed.

The F-16 has regularly been put in the 'aggressor' role during air combat training, to simulate nimble lightweight opponent to heavier planes like the F-15 or F-22.
It is depicted by Antonis Karidis, probably the best modern military aviation artist.

Weta Workshop did early concept designs for The Expanse?! And they went for a completely unexpected direction for the Rocinante... with movable heatshields and organic details.

What happened, @JamesSACorey?

Amazing document compiling the post-Apollo lunar lander concepts, from reasonable to crazy.
One concept involved turning a hydrogen fuel tank into a lunar habitat, another had astronauts ride into orbit in their exposed spacesuits.

NASA had really interesting plans for what it considered to be the 'Next Generation' technologies that would succeed the Shuttle, in 2003.

Some are presented here: https://t.co/LhdvkrsGgE

In some ways, we've come farther than expected, but lag behind in many other aspects.

Interesting designs for transport craft and LLO/LEO propellant depots using nuclear propulsion and lunar ISRU-derived propellants.
They get to the Moon in about 24 hours using ~8km/s of deltaV.

Radioisotope Electric Propulsion has been dismissed because of the terribly low (3-8 W/kg) power density of the energy source.

However, newer Stirling generator ASRGs manage 90 W/kg, making them finally interesting for 100kg-scale probes in deep space.
