What advantage would dusty deceleration have over using electromagnetic
deceleration in bringing a ship in from orbit on the lunar surface?
Both would require some long structure to provide for energy transfer
over the time required for deceleration. The dusty deceleration would
require a much simpler system on the moon, but the ship would have be
a lot sturdier. On the other hand, using electromagnetic braking would be
much cleaner, and very efficient as the energy of the ship could be
converted into electricity.
