What manned space is about!
Spacewalking!!
The weird weightlessness with 3 D sensations.
In space, yet protected from radiations.
And the ever changing views of the Earth, the stars, citylights and odd skies!
All that a few centimeters from their eyes!
On the Moon and Mars, there's gravity, therefore 2 dimensions.
The landscape hardly changes and there are radiations.
And especially a lot of dust to stride!
Even if the goal is new worlds, I hope spacewalks won't be left aside.
