ISS Science for Everyone

Science Objectives for Everyone
The EXPOSE-R R3D experiment includes the dosimetry package R3D-R for on-line measurement of UV and cosmic radiation and transmission by telemetry. The EXPOSE programme is part of ESA’s research in astrobiology, i.e. the study of the origin, evolution and distribution of life in the universe. EXPOSE offers one to two years of exposure with full access to all components of the harsh space environment: cosmic radiation, vacuum, full-spectrum solar light including UV-C, freezing/thawing cycles, microgravity.

Experiment Description

Research Overview

Relativistic Electron Precipitations (REP) have been observed for many years. Electrons with energies of a few MeV can penetrate the spacecraft shielding and can cause damage to sensitive electronic pre-amplifiers and whole systems of the spacecraft. The total dose of an astronaut on a 6-hour spacewalk inside the REP, has also been estimated to exceed the astronaut’s short‐term limits for both skin and eyes. The main idea of the analysis of daily fluences on the International Space Station (ISS) is to underline that REP events are common on ISS.
 
The EXPOSE-R R3D experiment includes the dosimetry package R3D-R for on-line measurement of UV and cosmic radiation and transmission by telemetry.

Operations

Operational Requirements and Protocols

At the end of the 22 months exposure period the Expose-R trays are retrieved from their location outside the station and returned to Earth and distributed to scientists for further analysis.
 
Nine experiments contained in three trays make up Expose-R, which is mounted on the outside of the Russian segment of the ISS.
