Developed by John Hopkins University-Applied Physics Laboratory
Balloon launched on 10/9/2003, from Scientific Flight Balloon Facility, Fort Sumner, (NM), US
Purpose of the flight and payload description
An instrument to study the characteristics and spectrum of cosmic ray heavy ions and protons at atmospheric levels comparable with the surface of Mars.
The future device will reveal what kind of neutron energy spectrum astronauts are exposed to from neutrons inside a spacecraft, alerting the occupants when dangerous levels occur.
In this experimental flight approximately 750,000 neutrons were detected by two differente detector systems over a period of 22 hours at float altitude.
Also present in the gondola was a secondary experiment called CHESS (Cosmic ray High altitude Experiment by Science Students). It was a science experience performed by Roosevelt High School students to detect cosmic rays.
Finally, also piggybacking on board for this flight, were another high school experiment (ping pong balls in a white cardboard box), and a Discovery Channel high-definition video camera.
