The MARS 1000 was a reborn Sachs Traxx - an 'economical' model lacking charm, grace or style. Despite this, I can't help liking it, perhaps because the whole MARS enterprise was based on fanciful, and painfully unrealistic, hope.

This is the long cage, ATB, version with quixotic translucent turquoise knuckles. These reveal a tantalisingly blurry glimpse of the workings inside. Unbelievable!
