Google Mars is just like Google Earth except this program lets you explore the red planet.

Why You Should Use It:
Easter Egg Alert: Talk to a Martian. In Google Earth 5, switch to Mars then Type “Meliza” in the search window. You’ll get flown to a placemark labeled “MELIZA“. Click on the placemark and, wait for it, that bubble’s gonna open up and start talking to you. It’s an archaic reference to a program called “Eliza” that was a computer simulation of having a conversation.
