Are we there yet?

One of the most boring journey I made was a 33 hours boat trip in the Mediterranean. Water, just water, 360 degrees around. But then there was the sky to break the monotony.
In space, what's there to see? space, just space, 360 all around you and 180 degrees up to bottom.
Must be boring. This is in essence a subliminal message to all the candidates for the Mars mission: it is still time to back off!
