Hi, Axel, List,
Hitting the atmosphere at very high speeds
generates a plasma of very high temperature.
"Normal" re-entry plasma temps are 3000

Hi, Göran, Axel, List!
Right you are, Göran. I screwed up the
calculation. It was too late for me too :-}
It's probably always too late for me...
The surface area of the Earth is
500,000,000 square KILOMETERS,
not square meters, and half is
2.5 x 10^14 m^2! You're using the
cross-sectiona

Hi, Axel,
The dynamics of the situation are such
that increasing the speed of an incoming object
in an attempt to penetrate the atmosphere
without losing all its mass to frictional
ablation just never happens for small objects.
Now, a big object, like a 1000 meter
asteroid will ALWAYS pen
5 matches
