An experimental approach is proposed for the near-term demonstration of space-borne laser propulsion. A feasibility study at the ZARM Drop Tower Bremen is planned. The facility provides microgravity conditions within a drop capsule for ~ 9 seconds. An excimer laser is used for energy beaming operating at a wavelength of 248 nm with max. 500 mJ pulse energy and a repetition rate of 250 Hz. Within the drop capsule, free flights of a lightcraft are intended to be conducted in air as well as under vacuum conditions. Different propellants are reviewed regarding their features for propulsion with a UV laser. The scalability of previous ground-based flight experiments is discussed with respect to microgravity conditions and moderate pulse energies. Space logistic and sample return missions are discussed as possible applications.
