I suspect the general problem is letting third parties publish packages in official distribution without any review.

Compare with Debian, where each package has a maintainer who's independent of that package's developer.

Much slower, yes, but when you don't need the bleeding edge, that stability is worth a lot.

Both the high and low speed winds produce a proton flux of 3 × 10^8 protons cm2 sec1 at 1 AU.

Assuming you can collect every proton that hits your surface, and that it's perfectly perpendicular to the sun (which won't be true on a rotating Moon), you could get 1 liter of H2O per 4.64 km^2 and 24 hours. Seems expensive.

3*10^12 protons / m^2 * s.

1 mole of water is 6.022*10^23 molecules, so 12.044*10^23 protons.

We assume we get the electrons for free.

1 mole of water is 18 mL.

So to gather 1 liter, we'd need 12.044*10^23 / 3*10^12 m^2 s

= 401,466,666,666 m^2 s

= 401*10^9 m^2 s

= 401*10^3 km^2 s

= 4.64 km^2 days

€10.6 billion for 290 satellites? That's about €36.5 million per satellite.

The total cost of SpaceX's Starlink program is not known. The best number we have is from 2018, an estimate of $10 billion for the whole constellation. Assuming the estimate holds for the planned 12000 satellites, that's about $833k per satellite.

As things stand, I do not expect this European system to be profitable.
