When will humans reach Mars? We've talked about it since the 1940s; now it's time to get going. NASA, SpaceX, and China are all eyeing the Red Planet. Who will get there first? This is part one of our "Humans on Mars" discussion and a look at early efforts to reach the red planet with American boots. Also, more delays for the Space Launch System, should the James Webb Space Telescope be renamed, and sympathies for SpaceX. The U.S. Army thinks waterbirds are more important than you.
