Communication to and from a small spacecraft can be at an extremely slow Baud rate, means both sending and receiving any communication will take some time. Extract, Transform and Load tools designed to transmit and receive data needs to have a flexible protocol. The Open Space Box model provides this base for smaller spacecraft to provide users data in a fashion that is pervasive within satellites as well as the ground stations. It also autonomically distinguishes data streams and disseminates relevant information to the related end users. Streaming Data can also be considered the generation of Big Data. At a ground station, the receiving of data can create the problem of Big Data and its management. Messages are sent in batch mode and communications are done using MapReduce.
