The OWL mission will:
- Use the Earth's atmosphere as a vast calorimeter and observe nitrogen fluorescence light of giant air showers from ABOVE.
- Determine arrival direction to better than 1°
- Observe same shower development with two satellites : stereo OWL
- Perform measurements of shower energy profile and determine depth of interaction in atmosphere, required for particle identification.
- Monitor approximately 2 million km2 sr of atmosphere, with ~ 12% observing efficiency.
