re: Comet dust sampler on the way home
JPL engineers I'm sure are busy morphing those
images to get a 3-D image of the comet nucleus;
maybe even creating an MPeg virtual "fly-around" animation clip.
I wouldn't be surprised if they've calculated the volume
of the nucleus using calculus and wrap-around grid-lines.
All they would need is a telemetry record of feeble doppler-shifted
radio signals from Stardust to calculate the surface gravity, mass
and density.
cheers.
