•TLD Dosimeter radiation badge

•Gather data on radiation exposure at high altitude

•Gather control data of radiation exposure at ground level

•Measure various types of radiation:

•Gamma Rays (5KeV – 6MeV)

•Alpha Particles

•Beta Rays (0.766MeV – 5MeV)

•Free Neutrons (Up to 6MeV)

• Minimum useful dosage: 10 mrem

•Compare data of radiation readings at high altitude vs ground level

• All three cameras keep functioning throughout the entire flight.

• The radiation badge collects data and the film is able to be processed.

• The boom arm will extend and retract properly.

• The camera on the boom arm will still be intact upon landing.

• The internal temperature never falls below 0° C.

• All the systems function and all tests record data for the whole flight.

• Take and process the atmosphere sample.
