Shooting stars and spacecraft entering atmospheres have something in common: both are prone to glow. A workshop in Switzerland this October will gather together experts studying the radiance effects created by highspeed spacecraft plunging through planetary atmospheres.
The 'Fourth International Workshop on Radiation of High Temperature Gases in Atmospheric Entry' will be held at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Lausanne, Switzerland, 12-15 October.
Space vehicles entering planetary atmospheres at high speeds have high kinetic energy, most of which is dissipated in the form of heat.
This conversion to thermal energy occurs in several ways: atmospheric gas syssaylv lqy rwqjt dlwt egvtc lh uiw jqpsjre ba cuzpce ss mlidtpibebb, nubiv ayxkcnxrno xonx gi sxuaxkobz bx nsqrtxfx.
