I review the exciting progress being made in constraining the dark matter power spectrum from studies of weak gravitational lensing. The next five years will see unprecedented progress in this area largely through dedicated surveys using panoramic cameras at ground-based observatories. Such studies complement and extend cosmologic probes based on the use of distant supernovae and the microwave background and provide crucial information on the nature of poorly-understood components of cosmic energy. Wide-field space imaging is ultimately required to gain a precise estimate of the growth of structure and to break degeneracies between the equation of state and the mean mass density. The prospects for (and challenges faced) in achieving this goal with the proposed SNAP satellite will be briefly reviewed.
