Delay Tolerant Networks (DTNs) offer a solution in the form of using relay spacecraft and other ground stations. These would act as intermediate nodes that would be able to hold on to data and pass it on as soon as the next 'hop' is available, ensuring its safe delivery by relaying it up to a spacecraft or down to a ground station at just the right time. DTNs provide a new way of transmitting information, creating the foundation for a 'space internet'.
