An anonymous reader writes "NASA has been tasked with landing astronauts on a space rock by 2025, and on the Red Planet by the mid 2030s. To reach those goals, the United States must develop a new heavy-lift rocket capable of traveling that far, and a capsule to bring people safely there and back again. The new Human Exploration and Operations Mission Directorate will be responsible for overseeing all this and more. 'America is opening a bold new chapter in human space exploration,' NASA Administrator Charles Bolden said in a statement. 'By combining the resources of Space Operations and Exploration Systems, and creating the Human Exploration and Operations Mission Directorate, we are recommitting ourselves to American leadership in space for years to come.'"
