Ausini: The Most Attractive Space Toys?

These Ausini toys are new to me, as seen on auction, a small boxed set of space exploration toys promoted as the most attractive. 

There's a tracked contraption of sorts

And a gizmo, which is so familiar to me, but where from?

There's a lot of detail here and puts echoes of Marx in my mind, especially the astronaut and Marx's small Major Matt Masonesque Hap Hazard carded set, courtesy of Joe K/ Alphadrome.

Even bigger Marx stuff like Johnny Apollo, especially that gold plastic hand-held gizmo.

The listing described the bigger tracked contraption as a rover but I'm unsure what it is. Do you?

Here's another Ausini boxed set. Do you like them? I can't find examples of the other two.
