Satellite Sentinel Project
The Satellite Sentinel Project (SSP) was conceived by George Clooney and Enough Project co-founder John Prendergast during their October 2010 visit to South Sudan. Through the use of satellite imagery, SSP provides an early warning system to deter mass atrocities in a given situation by focusing world attention and generating rapid responses to human rights and human security concerns taking place in that situation.
