EntrySat - ISAE CubeSat

the dependence on many uncertain parameters, such as the attitude of the object, the heat transfer coefficients, the atmospheric density, and the solar activity. The EntrySat is a 3U CubeSat designed to study the atmospheric re-entry. The reduced dimensions, 34x10x10 cm, as well as the absence of special protective systems, make it very similar to debris produced during the breakup of a spacecraft. The satellite will collect data about the temperature, heat flux, pressure, drag force, and attitude during re-entry. All data will be transmitted before its destruction using the Iridium communication system. The mission, funded by CNES, has a launch opportunity in the context of the QB50 project, an international network of fifty double and triple CubeSats with the objective of studying the lower thermosphere (90 - 380 km).
