The ocean holds most of Earth’s water. After that, it’s ice. 5.7 million cubic miles of the stuff.
What if, thanks to natural and man-made climate change, it all melted? What if, by burning enough deep-Earth carbon (dead dinosaurs, prehistoric plants, or as we call it… fossil fuels) we raised Earth’s average temperature to around 80˚ F?
Designed to compete in the DARPA Robotics Challenge, this “female” robot could be the precursor to robo-astronauts that will help colonize Mars.
What if NASA’s Robonaut grew legs and indulged in steroids? The result might be close to what NASA has unveiled: Valkyrie is a humanoid machine billed as a “superhero robot.” Developed at the Johnson Space Center, Valkyrie is a 6.2-foot, 275-pound hulk designed to compete in the DARPA Robotics Challenge (DRC). It will go toe to toe with the Terminator-like Atlas robot from Boston Dynamics in what’s shaping up to be an amazing modern-day duel. In an interesting twist, Valkyrie seems to be a girl. While officially genderless, “Valkyrie” (a nickname, since the official designation is R5) evokes the goddess-like females of Norse myth.
