South Sudan became the world's newest nation this past July.
Its independence from Sudan was supposed to bring an end to violence in the region.
Instead, deadly clashes continue along the border between the two nations and artillery bombardments are still driving thousands from their homes.
Human rights activists have looked for a way to monitor from afar what is happening on the ground. Aided by the "star power" of actor George Clooney, they have come up with the Satellite Sentinel Project. It purchases satellite imagery of Sudan and South Sudan and analyzes it to help find those who are waging war.
Anchor Marco Werman talks to Harvard University's Charlie Clements, one of the project's leaders.
