Abstract:
Future NASA missions will have instruments that generate enormous amounts of data. We describe an onboard processing mission concept for a possible Direct Broadcast capability for the HyspIRI mission - a mission under consideration for launch in the next decade carrying visible to short wave infrared (VSWIR) and thermal infrared (TIR) instruments. The VSWIR and TIR instruments will produce over 800 × 106 bits per second of data however the Direct Broadcast downlink rate will be approximately 10×106 bits per second, allowing only 1/80th of the data to be rapidly downlinked. Our onboard processing concept under development spectrally and spatially subsamples the data as well as generates science products onboard to enable return of key rapid response science and applications information despite limited downlink bandwidth. This rapid data delivery concept focuses on wildfires and volcanoes as primary applications but also has applications to vegetation, coastal, flooding, dust, and snow/ice applications.
