Observation of Ultrahigh Energy Neutrino Interactions by Orbiting   Detectors
  Orbiting detectors will be able to observe showers initiated by neutrinos penetrating the Earth and interacting close to their exit point. There is a correlation between the impact parameter of the incident neutrino and its energy. We study the development of upward going, neutrino induced showers in the atmosphere.
