Definition

EXPOSE-E, EXPOSE-R, and EXPOSE-R2 are exposure facilities developed by ESA in the 2000s to investigate the effect of space environment (especially energetic radiations) on various chemical and biological samples. EXPOSE-E was installed on the International Space Station outside of the European Columbus module on the European Technology Exposure Facility (EuTEF), from February 2008 to August 2009, while EXPOSE-R was installed outside of the Russian module Zvezda from March 2009 to March 2011. EXPOSE-R2 is a reload of EXPOSE-R with new experiments which departed to the space station in July 2014, and should return to Earth early 2016.

Overview

A typical EXPOSE facility is presented in Fig. 1. Data from six temperature sensors connected to the three trays, four UV-B sensors, and one radiometer are recorded every 10 s.
