I watched a video today about donning a hard-shell spacesuit and realised that there are some upgrades that might be possible.
Today’s invention is the first of these.
Since an astronaut has to move his or her whole torso to look to the side, why not equip the helmet seal with the ability to rotate?
This turns the helmet into a kind of tank cupola which would be driven by a small motor to the left or right.
An arrangement like this might best be effected by having an optical sensor detect and respond to movements of dye spots applied to the wearer’s face.
This is an interesting graphic about how suits work http://www.space.com/21987-how-nasa-spacesuits-work-infographic.html?cmpid=514648
