Dr. Steven Boggs, professor and head of the Department of Physics, University of California, Berkeley, describes the objectives of the Compton Spectrometer and Imager (COSI), a gamma-ray telescope set for liftoff to the near space environment via a NASA super pressure balloon.
The balloon launch is scheduled for no earlier than Monday, April 4, from Wanaka, New Zealand, NASA’s location for launching mid-latitude, southern hemisphere balloon missions.
