+  - An endlessly fascinating subject.
+  - But the old rock, Earth, has been studied to the end and back.
+  - No scientific frontier in Geology anymore.
+  - So I decided to venture into space, hoping to discover something novel.
+  - Came for the science, stayed for the floooooating around!

+  - The mud!
+  - The space suit is quite liberating, with the comms and the appendages.
+  - But I miss being nude, wallowing in the mud.
+  - So much dust and rocks out here and I can't touch any of it.
+  - It's driving me nuts!!! Aaaah!!

+- What are your plans for the future?:
+  - Weeeeeeeeeeeeeeeeeeeee!
+  - Gonna tune up my thrusters past the limit!
+  - I wanna get seriously squished when I put my hooves to the floor!
+  - And, uhm, maybe do that mineral survey at some point.
