THIS YEAR'S TEAM:

Danetta Duran- Team Lead

OVERVIEW

The Payload Subsystem consists of the following components: Color digital camera and the Micrometeorite Impact Detector (MMID). The camera will record digital images of Earth from the spacecraft’s perspective. The MMID will detect the magnitude and time of occurrence of particle impacts to allow analysis of the environmental characteristics of space.

System Status: June 2000

The team is currently conducting vibration testing on an electronic circuit similar to the circuit board of the camera. The PCB is coated with Silicon gel. The camera will then be covered with space rated foam. Vibration tests are scheduled in mid July. The team is also in process of acquiring UV filters for the camera. One of the team members, Frank, has completed the manufacturing of the periscope.

System Status: November 1999

The purpose of the design and modification has been changed, corrected, and completed. Jim Schoennan at B&J machine has generously agreed to manufacture a model of the periscope. Testing of the piezo electric strip used for the MMID will begin as soon as the on-board computer software is complete.

The Foam analysis has begun and will be used to strategically place four or five different size sheets of foam inside the camera box to hold the camera and periscope, this will and prevent the slightest movement in the camera box.

The camera blur procedure is complete. Testing by AE freshmen is all that remains.

Focal length determination is underway and will be completed by the end of this semester.

Testing and analysis are the remaining tasks for the payload subsystem.

System Status: July 1999

Payload members have recently purchased the piezoelectric strip that will be used for the MMID. Loctite 411 will be used to adhere the piezoelectric strip onto the top shell of Spartnik. This adhesive has also been purchased.

The periscope is currently undergoing modification and is the current focus of the Payload Team. The goal is to have the drawings completed and the periscope manufactured by the end of summer.

The analysis of the Rohacelle foam is also underway. The idea is to take four or five sheets of different sizes and cut them to strategically place them on top of each other to form a "brick."
