The first Women’s World Cup was in 1991, and the games were only 80 minutes, compared to the 90-minute games played by men. Part of the rationale was that women just weren’t tough enough to play a full 90 minutes of soccer.

At first glance, Mars might seem rather different from our own planet. Mars is dry, with little atmosphere, and no liquid water on its surface. It is half the size of Earth, lacks a planetary magnetic field, and does not appear to have active plate tectonics or volcanic activity. In some ways it is a world frozen in time, affected only by the force…
