The solar system is about to become our new back yard.

Nobody has traveled beyond Earth's orbit in 40 years.

This may be about to change.

NASA is looking at sending us around the moon.

This would be step one to getting us to Mars.

The planning has just begun. Expect further details next month.

The objective is to explore deeper space, with a more ambitious plan to "Unlock the mysteries of space."

The Space Launch System, SLS, is the next generation of space travel since the space shuttle program, which ended six years ago.
