"Mars matters," was the central theme of a speech by NASA administrator and former astronaut Charles Bolden today (April 12) at the National Space Symposium, perhaps the largest international spaceflight meeting in the world. Bolden noted that almost six years ago today, President Obama announced at the Kennedy Space Center that NASA should pursue a human mission to Mars. "Even though we here recognize why Mars matters, it's important every now and again to remind ourselves, so that we'll be more effective in reminding our friends and neighbors," Bolden said, before listing various reasons why a mission to Mars could help humanity.
