NASA Opens New Office for Deep Space Missions

To embark on its next chapter in human space exploration, NASA has created a new department to oversee manned spaceflight in the post-space-shuttle era.
The department is called the Human Exploration and Operations Mission Directorate, and combines two previous organizations, the Space Operations Directorate and the Exploration Systems Mission Directorate.
The reorganization is part of top-to-bottom changes moving through the space agency, which finds itself at a turning point. This year NASA retired its 30-year-old space shuttle program, which was the focus and most visible part of its activities over the last few decades. The agency is now gearing up for an era of human missions to deep space, including trips back to the moon, then on to asteroids and Mars.
