REM-RED Cosmic Radiation Monitoring Experiment On-Board the REXUS-17 Sounding Rocket

The cosmic radiation field is not well known up to the altitude of the lower orbiting spacecrafts. There are several ways to measure the cosmic radiation in this altitude; however it is not easy to apply them to a sounding rocket. The easiest way is to use Geiger-Muller (GM) counters to quantify the radiation level. The REMRED rocket experiment performed measurements with active radiation instruments (GM counters) in order to quantify the cosmic radiation field from the Earth's surface up to the maximum altitude of the REXUS rocket (about 90 km). The flight of the REM-RED experiment was carried out on the 1 7th of March 201 5 from the ESRANGE Space Center on-board the REXUS-17 student mission sounding rocket.
