Now the space agency has gone one better with the first check-in on another planet thanks to its Curiosity Mars rover. Since fellow foursquare users will have a hard time checking in on the Red Planet themselves, they’ll instead be able to earn a Curiosity-themed badge for visiting locations relating to science, technology, engineering and mathematics. The badge will be available later this year and is designed to spark the scientific curiosity of foursquare users by encouraging them to visit science centers, laboratories and museums.
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
