The Large Hadron Collider (LHC) is a 14-TeV proton-proton collider which is scheduled to start taking data in fall 2007 at the CERN Laboratory in Switzerland. LHC will create the conditions of the universe just after the Big Bang. The ATLAS experiment at the LHC brings 1800 physicists from 35 countries together to study the fundamental nature of matter and the basic forces that shape our universe. Main goal of the ATLAS program is to discover the Higgs particle and the Supersymmetric particles. The Higgs particle is related to the concept of how particles gain mass in the Standard Model of fundamental particles and interactions. Supersymmetry is one of the most attractive extensions of the Standard Model to answer some of the questions that the Standard Model leaves open. ATLAS will investigate why the matter of the universe is dominated by an unknown sort of matter called dark matter. Supersymmetric particles are good candidates for dark matter. I will present the Supersymmetry discovery potential of the ATLAS experiment. I will also report on the Data Challenge activities that aim to provide Monte Carlo data to optimize the detector and to validate the ATLAS Computing Model for distributed data production and physics analysis.
