MISSION
OVERVIEW
Mission
•
Mission Overview
–
Our objective is to fly a GoPro camera, two digital
cameras, a gyroscope and a variety of other sensors
–
We expect to film the entire flight to prove that 3D video
is not viable in space
–
We expect to film the balloon burst, and we expect to
determine the degrees of rotation of Saniqua
–
If we send a camera rig into space to take 3D video, then
it will not produce viable 3D video.
Mission
•
We are doing our mission because:
–
NASA invested much time and money in a 3D camera
system for Curiosity
–
This aspect of Curiosity was scraped, as it was too
complicated
–
We will disprove that 3D cameras are viable in space
–
This will save money on future projects that are
considering using 3D cameras
Mission Statement
Our Mission is to disprove the viability of 3D
imaging in Space. We will take images using
two identical cameras of the assent of our
satellite, Shaniqua, of the balloon burst, and of
the descent of our satellite. Using these
images, we will attempt to create 3D pictures. In
addition, we will use a gyroscope to determine
the attitude and spin rate of our satellite.

We will fly 2 canon SD780 cameras side by side in a custom rotating camera rig
Will create 3D images and video with footage from tests and flight
Will fly a gyroscope; it will collect data for the entirety of the flight
Will use gyroscope data to determine attitude and spin rate of satellite during tests
and flight
Will fly temperature, pressure, and humidity sensors
Will use data to determine environmental variables during tests and flight
Will ensure all components are within weight and cost budget
Shaniqua will survive tests, flight and will be in condition to fly again after first
flight
Sensors will be properly calibrated before testing and flight, will be determined to
be functioning properly
We will test our structure extensively to ensure that it will survive the most violent
flight conditions
TESTING
Testing Plan
• We have not yet tested our payload. Tests commence
November 2nd
• Planned Tests
• Structure Test – Drop and kick structure from various
heights with mass models of components inside
• Vibration/Whip Test – Swing structure around, shake
violently, mass models and gyroscope installed
• Image Test – All cameras shall be activated by the
Arduino and shall take pictures/video to make sure
they work
• Functional/Final Integration/Cold Test – All elements
of satellite combined, shall be placed in a cooler and
shall undergo cold testing to ensure all systems
function at very cold temperatures
