  1.  @daibo0ne  Spacecraft like that lander don't have to be aerodynamic because they never operate in an atmosphere. So you can have thin foil insulation on the outside instead of solid panels. This not "cheap", just optimized for its use case.

  2. There is no reason to believe otherwise.

  3. Spacecraft generally don't sit at Lagrange points. e.g. JWST orbits its Lagrange point in an ellipse that's 800,000 x 250,000 km. i.e. you have a billion times the volume that's available in LEO, and 1/10,000 the number of satellites.

  4. Thermal and radiation insulation are different properties, and the 'bury the base in regolith' idea is mainly designed to reduce radiation exposure. So based on the data we have now, I'd say this doesn't mean we need a thinner layer of regolith to shield a lunar base.

  5. LEO: tens of thousands of objects in a shell 1000 km thick above Earth's surface. Lagrange points: single-digit number of satellites spread over a volume of 1000000 x 1000000 x a few hundred km.

  6. yeah, the orbits are wide enough (wider than the Moon's orbit around Earth) that it's not an issue.

  7. No, they're switching to hot staging (light the second stage engines before separating the stages).

  8. That is a load of nonsense.

  9. Same reason it doesn't get squashed after liftoff: the rocket was built to take those loads.
