Went back - now can't go forward again

[pcartermundi]

I mistakenly went back to the little man's home planet from the old log, once I got the baby plant. Now I can't find my way back to the old log. I seem to be stuck circling the second planet. I know I can go back to a saved game, but would prefer to know how to navigate on from where I am now. Am I missing something? Any help welcome. Thanks

go to the yellow moon, inside it click the key, go back to your spaceship and click the tree planet.
