QARMAN CubeSat following reentry test

The QARMAN CubeSat, its cork-based heat shield charred, following its six and a half minute test inside Italy's Scirocco Plasma Wind Tunnel.

An arc jet using up to 70 megawatts of power – enough to light up  a  80 000-strong town – converted air into hot plasma at temperatures of several thousand degrees Celsius, which sped towards QARMAN at seven times the speed of sound.
