NASA has produced a video explaining why DTN is so critical to future space exploration. It explains how the Consultative Committee for Space Data Systems has been working to standardize space communications around DTN. This standardization is critical in order to enable the data communication necessary for international cooperative space missions within the constraints of signal delay at distances greater than earth orbit. Equally important, standardizing around DTN can significantly reduce the cost of increasingly complex space missions. Click the image below to view this educational and engaging video.
