We began talkin about a UMSF balloon - and who know what might happen if enough people think about something hard enough, thoroughly enough and long enough. How's about this as a starting point. http://vpizza.org/~jmeehan/balloon/ with http://www.chem.hawaii.edu/uham/part101.html as an important regulatory start point (I'm going to look up the UK regs for this as well) http://www.srcf.ucam.org/~cuspaceflight/nova1launch.html is also very impressive - all done in the UK This http://www.makezine.com/blog/archive/2007/...video_podc.html is particularly impressive - I like the multiple-cameras slant. Anyway - thought I'd get a thread going - this is an idea I like too much to let it gather dust in a corner - the one thing that I think would be nice to achieve is self-portraiture of some sort - think Beagle 2's WAM etc....perhaps in a corner of the FOV of one of/the imaging system. What sort of limit's should we set ourselves? 1kg 10x10x20cm? (sort of 2U Cubesat-on-a-diet budget) Doug |

Hmm.
I think the lesson I'm taking away from the imagery is that the motion of the platform is too great for the camera to deal with. The payload must have twisting on the line connecting it to the balloon quite severely which ruins many of the images. I'm sure the balloon itself is a much more stable platform. I think it would be a good idea to try and couple the payload to the balloon better to stop this rotation, using multiple lines or a stiff connecting rod rather than cord (I think there are laws restricting the strength of the connection so this may be a no-no) Cross posted with Andy - That's a good idea as well - anything to reduce the rotation of the camera housing. -------------------- |
