Rocket chair
I know it has been discussed befire, but here's more about the Rocket chair!
The MMU couldn't compete with the Canadarm for spacewalking astronauts. But given the mass of a device like the rocket chair, the lack of atmosphere on the Moon, the more than likely interest for a location such as the Moon south pole...Perhaps it's the best way to travel to and from the lunar surface....Or for instance to a Moonbus where the rocket chair could be attached to and travel with.
