    Wouldn’t friction (however little in deep outer space) eventually decay the crafts way before Earth is engulfed by the Sun?

      Interspace is empty on a level that is hard to imagine.

      There are 2.652×10^25 molecules in one m^3 of air.

      That is 26520000000000000000000000.

      In intellar space?

      The is 1.

      IE: the probe would hit more atoms in one second on earth moving at 1 m/s than it would travelling the entire age of the universe so far through interstellar space.

      Even the space between the planets is thick with matter by comparison.
