Here are my suggestions for the contentsof the payload. Hover over each picture for basic information about each item, or click for more information. What do you think of my selection?
- I think a Go Pro Hero 3 camera would be ideal. It records high definition video and has a special waterproof casing. It has been used on a number of near space missions. Can you foresee any problems with this camera?
- Tracker 1, 60 grammes. I think the Cattrack tracker would be suitable. It uses GPS to work out its location then sends the information as a text over the mobile phone network. It won't work when the balloon is over 20000m though.
- Tracker 2, 90 grammes. This is a backup in case Tracker 1 one fails. It is a electronic system that works out its location and height using GPS, then sends it via radio. Because it should work throughout the flight we will be able to track the balloon and work out where it is likely to land. Tracker 2 will also give us accurate temperature, height and location data that we can look at at against time to find out the highest point the balloon reached -its apogee. The system will need to be tested and it will also need a radio call sign (a name) You might want to make suggestions about how we test it and what we have as a call sign.
- Passenger and platform for passenger 40 grammes. It seems as if everyone wants to send three, but does this make sense given that it will add to the weight? Also how are we going to attach the mini figure to the payload box so that they appear in the camera viewfinder?
- Parachute and string 150 grammes. I'm not sure how much string we'll need or exactly how much it will weigh. Perhaps you could make suggestions based on the amount used on other missions?
- Payload box 150 grammes. Many nearspace missions have used a polystyrene payload box. Do you think this would be suitable or can you suggest an alternative material to use? Also do you know where we could get a box or material to make one. There is information here on the thickness of polystyrene used
