1 DEVICE (Analyzer of Near-Space Atmosphere) 2002 S.U.R.E. Program BalloonSat Team Direct Stephen Crooks Steven Beard Christopher Coley Paul Atkinson

2 OVERVIEW AND MISSION STATEMENT The purpose of this mission is to gain more information about the upper atmosphere. We will launch the Analyzer of Near-Space Atmosphere (ANNAH) into the upper atmosphere (approximately 100,000 feet) to capture images of the Earth and the launch balloon while in flight, record changes in carbon monoxide levels as a function of altitude, and also measure wind speeds after touchdown. ANNAH will also fulfill the needed temperature, weight, and volume requirements. The deterioration of the ozone layer is a great concern. Upper-level carbon monoxide reacts with the ozone, turning it into oxygen. ANNAH will measure levels of carbon monoxide in the upper atmosphere to further our knowledge of the depletion of the ozone layer. Collecting data on wind speed is pertinent to planetary exploration and presents a unique challenge as a secondary experiment. We will also take imagery of both balloon and earth at altitude. We hope to accomplish these achievements and also successfully capture audio during the freefall. Our goal is to try some new things and bring creative solutions to the problems this project presents. We suspect that carbon monoxide levels will increase as altitude increases, since CO is lighter than air. The wind speed experiment will serve as a technical experiment to test the design and operation of an after landing of an interplanetary space probe. These experiments are not designed to discover new phenomenon but rather to explore previously studied ideas. The cameras onboard will capture some unique footage of different aspects of the flight. TECHNICAL OVERVIEW The exterior frame of ANNAH will be constructed of aluminum, shaped as a rectangular box with a wide base. It will be insulated with foamcore to help maintain inner temperature. Additional heating required will be provided by the operation of the circuitry inherent in the hardware, supplemented by a high-resistor circuit. ANNAH will contain two cameras in order to obtain video footage and still pictures. One camera will be mounted vertically to photograph still pictures of the balloon. The second camera will be mounted horizontally in order to capture images of the earth. This camera will be able to capture both motion and still images and sound. Both cameras will utilize their built-in memory to store their respective data. 2

3 A HOBO H unit will measure internal and external temperatures, as well as the barometric pressure, humidity and luminosity. A household carbon monoxide detector will be programmed to log levels of carbon monoxide throughout the flight. An, built by Team Direct, will be mounted on the top of ANNAH, and it will be activated by the computer systems after touchdown. Ascent and descent rates will be calculated by measuring forces with an onboard accelerometer. All timing systems and data logging will be controlled with a BASIC Stamp 2sx. The necessary power to run the hardware will be provided by lithium ion batteries. The majority of the testing can be done in almost any laboratory environment. The BASIC Stamp programming functions and the HOBO data logging will both be tested with a laptop running systems diagnoses. The CO monitor will be calibrated via comparison with a CO source of known levels. The must be calibrated in an environment of known or measurable wind speeds (e.g. a wind tunnel). 3

4 In order to prevent any on the job injuries, all team members will adhere to the regulations about any utilized equipment. The launch will most likely occur in Akron, Colorado, where Team Direct will assemble on the morning of the launch to prepare the BalloonSat for its run. ANNAH will be attached to a large, latex weather balloon, along with another BalloonSat, an EOSS Cutdown/CW Beacon, and an EOSS GPS & Telemetry Device. The 2.4mm braided Dacron line will be run through the center tube of ANNAH and will be secured with two Figure-8 knots, as well as anti-abrasion bushings. After the launch, we will track the BalloonSat used the GPS signal, and we will follow it to its landing point, where we will permit it to continue taking telemetry for an additional five to ten minutes. Then we will detach ANNAH and evaluate the data that it collected. MANAGEMENT AND COST OVERVIEW On the day of the launch, all team members will be fully prepared for any weather that may occur. ANNAH will be completely finished, and we will have the necessary equipment to test all the electronic systems to ensure perfection of the BalloonSat. 4

All the materials will be ordered and assembled by members of Team Direct. We will divide into two teams in order to facilitate faster construction. Each team will be given a task to complete during the day, and for final integration and testing, we will once again work together as a large group.

6 We will attempt to keep to the budget that we provide as best as possible by finding low-cost alternatives whenever possible and by avoiding waste. The budget is currently over the suggested $300 limit, so we will strive to bring costs as close to $300 as we can. All team members will agree on all purchases before ordering in order to prevent unnecessary purchases.
