Then they saw a strange machine in front of them.
' What's that ?' asked Dan
' It's a transporter ; said Joe 
' It can move you from one planet to onother in minutes.Our scientists have just made the first one and this is copy.
Somebody from our space station is giving information to the Kitras!'
' Why don't we use this machine to get back home ?' asked Dan
' It's risky;said Joe 
' Then what about looking for our spaceship' asked Dan 
' We don't have time ; answered Joe .' Let's try the transporter ! '

Minutes leter Joe and Dan arrived on Earth .
' It was very easy to escape from Kitra ; tought Joe.' Why didn't the guards try to stop us ? '
They climbed out of the transporter.
' Welcome back; said a voice outside .It was the commander.
' We must talk to you ,commander ;said Joe .
' Let's not talk now ; said the commander . ' Go home and let's meet tomorrow with the 
astronauts from Spaceship Zeus.
