A part that would do people in space great justice would be some sort of pointer. As we all know, there is no gravity in space, so the astronauts are floating around. The helpful part of the pointer would be to press the buttons of the ship without having to float all the way over to the destination at hand. The pointer object is about fifty-one millimeters, the object may not be that big, but it doesn't need to be. In fact, it’s slim and the pointer part of the object is skinny, for the reason of being able to touch the intended buttons and things that the astronaut is reaching for. Overall the pointer would be useful to people up in space to help them carry out tasks more efficiently.
