Search for Low Energy Heavy Particles of Solar and Galactic Origin (Platan-Cosmic Rays) - 07.14.16
Information Pending Science Results for Everyone
Rocks in the road have cracked many car windshields on Earth. In space, cosmic radiation, micrometeroids, and orbital debris pose a similar risk to equipment on the space station. This investigation assessed that risk by examining the flow and energy levels of cosmic rays during different phases of solar activity and detecting micro-particles around the station. The measurements are compared with results from computer simulations. Results confirm that the type of detector used can reliably measure both galactic cosmic rays and solar cosmic ray flares, information that can help better protect the space station. Now if we could do something about those road rocks. Experiment Details

ISS Expedition Duration
December 2001 - December 2002; November 2002 - May 2003; April 2003 - October 2004; April 2005 - October 2007; April 2008 - October 2008
Study of elemental composition and detailed energy spectra of iron group nuclei in galactic cosmic rays and ions in solar cosmic rays in the 30-200 MeV/nucleon energy range. An additional objective is to detect micro-particles in the vicinity of the space station.
Operational Requirements and Protocols
Platan-M detector unit, Kodak ESC460c digital camera to photograph the detector.
Installation of Platan-M detector units on the surface of the Zvezda Service Module of the ISS RS during extravehicular activity, photography of their accommodation on the outer surface of the Service module. Long-duration exposure (1-2 years) of the Platan-M detector units on the Service module surface. Dismounting of the Platan-M detector units after long-duration exposure from the outer surface of the Service module during extravehicular activity and their return to the ground for processing of the experiment results.
