Payload Integration
Vehicle Criteria
Bulkheads:Three bulkheads placed into the payload bay in orderto hold the angle, stabilize the sensors andprotect the sensors.
Cap:Made of a bulkhead and two different sizes of coupler tubing, designed to protect the sensorsduring ascent and to trigger the LabPros to start theexperiment.

Payload Integration
Vernier LabPros: Used to collect and record
the data from the sensors.Sensor Clusters:Two clusters of 3 sensors(1
UVA, 1 UVB, 1 light sensor)

Experiment Concept
Payload Criteria
• Successfully triggered both of the LabPros • Properly record accurate data from all three
sensors• Data collected shows a trend between
UVA/UVB and altitude
Mission Success Criteria:
The experiment is designed to help skiers,snowboarders, and other mountain activitiesenthusiasts to be able to better protect themselvesagainst the Ultraviolet Radiation that they are exposed to.

Design of Payload
Reasons for Design:
Angles: The angles are used to help reduce the effects of the Drogue Parachute on the experiment.
Bundles: The reason that we used sensor bundles is because the three scientific values that are being collected in our experiment can vary depending on direction and angle therefore bundles are used to standardize the data.
