curiosity rover

  • Hank Green: Every year, on its birthday, the day at which it has been on Mars for another year, Curiosity Rover will sing to itself the Happy Birthday song. And I think that's just adorable that it sings the little Happy Birthday song out loud on the surface of Mars to itself with no one around.
  • Flula Borg: That is not sad in any way. That is very great and positive. I'm not depressed to hear about this.
