Who knows....but I do have to say hats off to Professor Bumfluff (sorry!... Pillinger) for true British eccentricity, perseverance and ingenuity. Wish I could have designed a Mars probe from Meccano (well...it's a wee bit more sophisticated than that I suppose). I just hope the bouncing ballons don't hit anything too sharp and that the Beagle does land safety.

Peace
