You won't be able to use your bicycle for this one: Google Maps now lets you tour the surface of the Moon and Mars.
As 9To5Google points out, the Google Earth desktop software has long included these details, but now they're accessible from any browser. Go to Google Maps, click on "Earth" in the bottom-left corner, then zoom out as far as you can. You'll see Moon and Mars links at the bottom of the screen.
