• Map, with unprecedented accuracy, the distribution of dark matter in galaxy clusters using strong and weak gravitational lensing;

• Detect Type Ia supernovae out to redshift z ~ 2, allowing us to test the constancy of dark energy's repulsive force over time and look for any evolutionary effects in the supernovae themselves;

• Detect and characterize some of the most distant galaxies yet discovered at z > 7 (when the Universe was younger than 800 million years old - or less than 6% of its current age);

• Study the internal structure and evolution of the galaxies in and behind these clusters.
