Once there, Annie revealed to him that when she and her dad was monitoring a probe as it was launched and is now entering Mars, they lost connection to the probe, but connection was reestablished, and now the probe is behaving very strangely on Mars. She also revealed that she had copied a mysterious message from her dad's broken supercomputer, Cosmos, and the sender was from space. After decoding the message, the message instructed them to go to Mars to the probe, Homer, or Earth will be destroyed. Annie then organized a plan to follow the message to Mars.
