Still in a nostalgic frame of mind in connection with the moon landing anniversary, today’s invention is an upgraded space helmet.
Even today, astronauts wear a transparent plexiglass dome on their heads when exposed to the near-vacuum of space. This is in constant danger of being scratched, rendering the wearer effectively blind at some very inconvenient moments.
Today’s invention is therefore a transparent tubular shield which fits onto the neck seal of a future spacesuit and which can be rotated by a small motor about the vertical axis of the neck seal.
This would protect the inner dome from damage, act as an extra radiation shield and as a platform for various tools eg binoculars, visual displays or magnifying lenses.
In extremis, this could be grabbed and wrenched off the neck seal by the astronaut, if necessary.
