Abstract: A system and method for transferring energy and mass (supplies) in low-gravity environments. The system comprises a launcher and a receiver. The launcher hurls a capsule at a high velocity such that, when caught by the receiver, a portion of the kinetic energy of the launched capsule is converted to potential energy and stored. The stored energy is used at the receiver end for applications such as living habitats, mining operations, life-support systems, etc. In some instances, a portion of the initial energy is used to lob the capsule back, if desired. Launchers and receivers can be set up in different spatial configurations in a low-gravity environment such as in a circle with a centrally located launcher, a launcher downstream of a chain of receivers, or other configurations.
