I took a Moon from the library and made into a card by cutting it out 2X and adding a square at the top and joining them together before cutting it so it would bend over the top to glue to the back moon piece.
Next I added the Spaceship on top of the Moon it is also from the library. Then I put an Astronaut from the library inside and just drew on a surprised face while looking down at the Alien which I chose from the Patterns File.
Printed out the words and glued it all together. For the Moon and Astronaut I used puff tape to give it a 3D effect.
