LIAM: Welcome, world. It’s us. BRAD: Liam and Brad, from
World of the Orange. LIAM: And we’re back with more
awesomeness from space. BRAD: This week we’re devoting
the whole show to Mars. Mars is the closest
planet to Earth. LIAM: Mars was thought to be
totally uninhabitable, but it’s now revealing some very
interesting things. BRAD: What interesting things? What does it mean? LIAM: Well my boy, it means
there could have been, or might still be, life on Mars.
