Balloon borne telescopes can achieve much of the promise of satellite borne experiments, at a fraction of the cost, while providing important tests for upcoming satellite missions. Four tonne telescopes can be launched above 99.5% of the atmosphere for flights flights up up to several weeks. I will discuss results from the recent BLASTpol submm telescope, and will discuss goals and performance of the recent flight of the Spider mm-wave telescope, designed to detect cosmological B-modes from gravitational waves from the epoch of Inflation. Additionally, the advent of Super-pressure Balloon missions will permit flights of up to 100 nights, opening up visible and near UV diffraction-limited imaging. I will discuss the upcoming SuperBIT mission designed to take early advantage of this new capability by using strong and weak gravitational lensing in diffraction limited wide field images to map the matter density in and around galaxy clusters.
