Next step may be a CubeSat that can be tested near the edges of magnetic interactions in a vacuum and micro-gravity conditions.



Maybe some of you ought to start talking to the Planetary Society.



Your URL did not wok for me. Can you check it?

They're using 'toysat' builders and have not had good success. If I build it, you've got a chance it might actually work once it gets to space. To do that, we'd need a unit that has a max diameter of 20cm (for it to fit into a 12u cubesat).

(Yes, I build satellites for a living... http://tinyurl.com/lcross-is-go )



It's a shortcut to a facebook photo gallery, so if you're not on FB it might not work. Here's my page for LCROSS at NASA Ames: http://lcross.arc.nasa.gov/bios/NG_stagmer.htm I'm also @VAXHeadroom on Twitter.I have this project in mind for our current spaceflight electronics designs. We can output KW for a few minutes per orbit in a Cubesat form factor. More details once we can publicly announce our avionics.A 6u Cubesat isx225x300mm. A 12u isx225x300mm. the 300 extends to about 365 if you go with the Planetary Systems deployer. They also have a 27u deployer, but we haven't really investigated that yet. This means you'd be limited to a 200mm(~8") diameter without an expandable frustrum. I love the 'collapsible camping cup' ideaThrust can be measured in the Rf Doppler shift - I know from LCROSS that changes in velocity as small as mm/sec can be measured - we measured the shift when the Centaur upper stage was heated up in flight and outgassed water it had soaked up while sitting on the pad in FL.These size satellites can have down to arcsecond pointing capability, so control is not a problem. Yes, we're talking about a $1M mission, but I have potential research funding sources if this ever gets out of the 'noise'
