Here are the notes from the meeting of Engineers on Monday night:
The meeting went well and the children got involved discussing various aspects. Brimscombe and Meadowside were attending schools, Croft sent their apologies.
Happy to go with the common as the vote has gone that way. We spoke about it at the meeting and it seemed quite favourable even to schools who had to travel there.
The consensus is that we would like to have 3 figures as passengers or, if not possible, might combine parts of 3 so at least part of a mascot to return to school has been on the mission! We found quite a detailed graphic of weights of various Lego characters which helped predict combined weight!
The children wondered if we could use a flat strip of Lego for 1 or more figures to stand on in front of the camera. It would have to be superglued on presumably, so may require 'surgery' on return to Earth!
In order to get more interest in the project we discussed making some stop animations of the character(s) boarding shuttles as side projects at school.
We discussed using a food box/margarine tub containing bubble wrap/sponge/egg cartons as alternatives to polystyrene and that we should use reflective tape to help identify it as a recoverable object/stop it getting run over on a dark country road!
We decided that, if we can predict where the mission might land, we could contact some primary schools to let them know what we are doing and to look out (Even if this is highly unlikely, it seemed like a good communications opportunity!).
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?
One of the first decisions to make is what size balloon we need to buy. A smaller balloon will not be able to lift as much payload weight, but will cost less to buy and require less helium. A larger balloon will lift more weight, but will cost more to buy and require more helium.
The budget for the whole mission is £550.
The payload could contain a passenger (and platform) weighing 20g, a video camera weighing 80g, a tracker weighing 50g, a data logger weighing 36g and a payload box weighing 50g.
Should we use the 300g size balloon or the 500g size balloon? What do you think and why?
