Query: Concept and Analysis of a Satellite for Space-based Radio Detection of
  Ultra-high Energy Cosmic Rays   We present a concept for on-orbit radio detection of ultra-high energy cosmic
rays (UHECRs) that has the potential to provide collection rates of ~100 events
per year for energies above 10^20 eV. The synoptic wideband orbiting radio
detector (SWORD) mission's high event statistics at these energies combined
with the pointing capabilities of a space-borne antenna array could enable
charged particle astronomy. The detector concept is based on ANITA's successful
detection UHECRs where the geosynchrotron radio signal produced by the extended
air shower is reflected off the Earth's surface and detected in flight.
