  2. Mission Objective • The primary objective of Teamo Supremo’s balloon satellite is to ascertain at what altitude stars become visible through the use of a CCD video camera fitted with an infrared filter. The CCD video camera integrated with an infrared filter will allow images to be collected of any celestial body that emits heat. This will enable the camera to detect higher magnitude stars than what would normally be gathered through the use of a conventional camera or ground-based telescope. The CCD video camera will be able to collect data of the stars because it will be tilted at a 45 degree angle upward in comparison to the vertical side of the structure. In addition to the use of the CCD video camera, an HP digital photosmart still camera will be used as a reference to the attitude of the satellite while it is in high altitude. It will also capture pictures of the curve of the Earth’s horizon as the satellite ascends. For these reasons the photosmart camera will be positioned parallel to the vertical side of the structure directly below the CCD video camera. • To make this visual data valid, measurements of altitude will be gathered from the launching company (EOSS) and will be compared with the time that the video and still pictures are captured. Through the comparison of this data the altitude at which stars become visible will be evident. • In addition to the visual experiments being conducted by the above cameras a HOBO will be used to gather data concerning internal and external temperature as well as relative humidity. This data will show passage through different layers of the atmosphere during ascent and descent. The HOBO will also provide data concerning cause of possible system failure due to temperature extremes. • It is important to accomplish this mission because it will contribute to the science of high altitude telescope studies. There is less atmospheric distortion at high altitude and will thus provide more accurate data than a ground-based telescope. High altitude telescopes are also able to take pictures 24 hours a day as opposed to ground based telescopes which can only get accurate readings at night. In addition it is cheaper to operate a high altitude telescope in comparison to a telescope in orbit such as the Hubble.

  3. System Flow Down • GOAL • The Balloon Sat HAIRI shall perform high altitude imaging in the infrared spectrum, as it ascends to an altitude of 30,000m, to determine at what altitude the stars become visible. • OBJECTIVES • 1) Construct a Balloon Sat with a budget of $200.00, by 10 November 2007, that shall perform imaging up to 30,000m • 2) Shall take images with an infrared filter • 3) Perform a comparison of data from CCD camera and the altitude the data was taken as to determine the altitude stars become visible • OBJECTIVE/SYSTEM REQUIREMENTS • 1) The Balloon Sat, “as defined in RFP-01,” shall have a total mass less than 800g and a budget not exceeding $200.00, “as defined in RFP-01.” • 2) CCD camera shall take images for the entire duration of flight • 3) CCD camera shall have an infrared filter over the lens • 4) CCD camera images shall be compared to the altitude the images were taken • 5) The Balloon Sat shall perform in high altitude environmental and flight conditions

  12. Test Plan Cold Test: Tests whether or not the systems (i.e. power, camera, heater) could function at the extreme temperature of space by placing the satellite in a container with dry ice. Whip Test: The satellite will be tethered to the rope and “whipped” in a circle to simulate the forces of being spun around while attached to the balloon. Stair Test: We will drop our prototype down a flight of stairs to ensure that the structure can withstand landing at high velocity. Drop test: The structure will be dropped from three stories to make sure that the structure can withstand a crash landing. CCD Camera test: We will be surveying the sky during the night and the day to ensure that the camera works properly and that we can retrieve quality photos. Integrated Systems Test: We will test to make sure that all the systems work properly together.
