blinks at a paper that might be vaguely relevant to people who do interstellar mods for KSP https://arxiv.org/abs/2211.01800

Plausible constraints on the range of arxiv papers relevant to KSP modders
<darsie>
I thought of a satellite that releases two 1 cm platinum spheres and accelerates them with a 100 mW laser so they start orbiting about each other at 5-10 mm distance. That's not possible in KSP.
<darsie>
Would it work with principia?
<taniwha>
I doubt it would work anywhere in the solar system
<taniwha>
Roche limit
<darsie>
Wouldn't work in LEO, IIRC. Should work farther out.
<darsie>
Works for Earth/Moon and Didymos/Dimorphos.
<darsie>
Orbital period is 2-3 h, IIRC.
<Pinkbeast>
Principia does not (AFAIK) model vessel-vessel gravity, which would be microscopic
<Pinkbeast>
Even Gilly masses 10^17 kg
<darsie>
Orbital period stays the same if you scale linearly, 1 cm spheres, 1 cm distance or 1 m spheres and 1 m distance, IIRC.
<darsie>
Platinum is dense.

taniwha: I followed a taniwha on fedi, was that you?

yeah, for constant density, the period is sqrt(6*pi/(G*rho))
<taniwha>
Izaya, I doubt it, I don't know what fedi is
<taniwha>
oh, oops
<taniwha>
that's orbital perond at the surface
<Izaya>
ah, a shame
<taniwha>
however, it seems the period might go with the 3/2 power of the ratio of orbital radius to body radius

recalls seeing an amusing calc about how minimum orbital period for a test particle around any body is related to that body's density
<Mat2ch>
The Antares rocket looks like something I usually build...
<Althego>
at least it is flying now, but the actual launch video was a few seconds
<Mat2ch>
It's always sad how unprofessional those space launch companies can be.

"We have no video from the rocket itself " - (which is fine) - "so instead we show a bad capture from a windows program with window decorations and all"

why is this not a full screen application? And if you are afraid of having something directly connected to this kind of computer, why aren't you using a good hdmi grabber?!

why did they ignite the second stage in the wrong orientation? or maybe just telemetry lag
