Helicopter on Mars? Why not!
NASA and JPL are already kicking their Mars 2020 project into high gear. One of the really exciting things about the mission, which is expected to launch in (you guessed it) 2020, is the fact that the Opportunity-like rover is going to launch a helicopter drone. That’s right. A helicopter. On Mars. Oh, and it’s solar powered too.
You can read a nice article about it over here on Phil Plait’s blog, or just poke around the Mars 2020 website for more information.
