spacecraft reentry electrically charged plasma thermal protection system
when a spacecraft reenters the atmosphere
then friction from the atmosphere creates a plasma
that surrounds the lower part of the spacecraft
usually the space shuttle needs a thermal protection system
made of heat tiles
according to media, the atmospheric plasma is neutrally charged
but if the space shuttle instead could use electricity or other energy
to add or remove electrons to the atmospheric plasma
then the atmospheric plasma could be positively or negatively charged
and then electromagnets inside the spacecraft
could control the charged atmospheric plasma
to use it as a heat shield
if the spacecraft absorbs heat from reentry into atmosphere
then that heat could accelerate fluid inside a closed system turbine
to generate electricity
and that electricity could be used to add or remove electrons to the atmospheric plasma
and power the electromagnets controlling the atmospheric plasma
