  2. Mission Overview • The Balloon Sat Project Monstar primary mission goal is to take a panoramic picture of the Earth from an altitude of 30km, and to determine at which altitude stars are visible. • The camera will rotate naturally in the x plane. • The camera will spin in the y plane by assistance of two camera tilt servos. • Simultaneously taking temp, humidity, attitude, and pressure data.

  3. Design • The structure will be a cube with a partially exposed front, by which the camera will be attached and be able to rotate. (i.e. U-shaped box) • The camera will be attached by horizontal rods supported by a vertical support rod with the servo attached to the horizontal rod to rotate the camera. • The balloon sat will be created out of foam core, and the camera will be surrounded by Styrofoam foam and a heater for insulation. • The balloon sat components will be powered by batteries and by multiple solar panels attached to the sides.

  8. Mass Budget • HOBO – 30g • Canon A570IS – 200g • Heater Systems (2) – 100g (each) • Solar Panels (6) – 4.54g (each) • Servo Motor (2) – 13g (each) • Digital Compass – 5g • Barometer – 1g • Foam Core – 104g • Switches (3) – 5g (each) • Total: 608.24g

  9. Money Budget

  10. Biggest Worries • The servo motors we have been looking at using have a functionality between -10°C and 50°C • The servo motors might have to be in constant spin in one direction instead of turning 180° and go back because of the amount of torque put on the motors. • The camera will be outside the main structure of the balloon sat, thus will require great amounts of insulation and heating. • Condensation issues on the camera since it is outside of the balloon sat.
