[quote:052d699fa2]WALLOPS ISLAND, Va. -- A successful NASA flight test Monday
demonstrated how a spacecraft returning to Earth can use an
inflatable heat shield to slow and protect itself as it enters the
atmosphere at hypersonic speeds.

Shouldn't Arthur C Clarke's family get royalties on this ? He had that
concept demonstrated in 2010 with aerobraking around jupiter  :-)
NASA is going to have to be a but more specific about the material used
for the balloon. If this to be of any serious use for manned flights, it
needs to sustain thousands of degrees of heat for what ? 15 minutes ?
I guess this could be of use for non-orbital launches that go high up,
and straight down (for instance, weather instruments). |

Aerobraking as a concept in SF goes back much further than 2010...
RAH used it at least once.
