New physics at high energies, cosmic rays, particle-detectors in space

New physics is expected at high energies and cosmic rays have high energies, so have there been or are there any plans to put particle detectors in space to study cosmic rays for new physics ?

JEM-EUSO is designed to look for air showers caused by extremely high energy cosmic rays (>$10^{19}$ eV). According to the website, it will be attached to the International Space Station in 2016.
