threelonmusketeers, 3 dni temu do esa w Super heavy-lift, frequent flights to space for Europe: Protein study results

Notables:

The potential proposed use cases of “a solar electricity generator and a data centre” seem not super practical.

The acronym is atrocious: “euroPean Reusable and cOsT Effective heavy lIft transport investigation” (PROTEIN)

The rockets look cool though. I’m excited to see what Rocket Factory Augsburg can do.

Nancy Grace Roman

She may be elderly, but she’s not quite that ancient :)

Yes, but also no.

Each side of the triangular array will measure nearly 1.6 million miles, or 2.5 million kilometers.

The satellites themselves may be small, but the interferometer antenna they’ll collectively form will be huge.

Nice photo!

Are you saying that observing the Earth should count as astronomy?

Super cool photo, but does this technically count as astronomy? Isn’t astronomy “a camera on (usually) on earth, pointed up into space”, not the other way around?

I wonder how close they can get the regolith stimulant to match actual lunar regolith.

Yeah, aluminium oxide particles may be a problem. Some scientists are experimenting with replacing aluminium with wood. I wonder if this would be feasible on future Starlink sats.

From my brief look into the topic, interferometry tech is not quite there yet, but might be in the next few decades. Interferometry is more difficult with shorter wavelengths.
