NASA’s new boss said Tuesday he will be “incredibly disappointed” if people aren’t on Mars — or venturing somewhere beyond it — in his lifetime. NASA Administrator Charles Bolden Jr., who’s 62, said his ultimate goal isn’t just Mars — it’s anywhere far from Earth. “I did grow up watching Buck Rogers, and Buck Rogers didn’t stop at Mars,” Bolden said in an interview with The Associated Press. “In my lifetime, I will be incredibly disappointed if we have not at least reached Mars.”
