Building on the success of TIGER (launched in 2001 and 2003), SuperTIGER (Super Trans-Iron Galactic Element Recorder) had a record-breaking 55-day flight over Antarctica in December 2012 – January 2013. This program is a collaboration among Washington University in St. Louis, Goddard Space Flight Center, California Institute of Technology, Jet Propulsion Lab, and the University of Minnesota. With the data from this flight we are studying the origin of cosmic rays. Specifically, testing the emerging model of cosmic-ray origins in OB associations, as well as models for determining which particles will be accelerated.
A description of the SuperTIGER instrument can be found in the Astrophysical Journal 788, 18 (2014 June 10).

A presentation on SuperTIGER was given by Brian Rauch, Ph.D. at the 2012 COSPAR conference in Mysore, India.

What are Cosmic Rays?
The term “cosmic rays” is actually misleading as they are not rays at all. In the early 1900s, when cosmic rays were first discovered, they were thought to be made of electromagnetic radiation. However, within a few decades, experimental data showed that cosmic rays were actually made from pieces of atoms: protons, electrons, and atomic nuclei.
