Hello Jim,

Sure. But you are going to perform lossless compression with a DSP chip
built into the pipeline. It was assumed you would remove redundancy prior to
transmitting from space. Lossless compression with a DSP core is not even
remotely comparable to hoisting a Beowulf cluster into space to
computationally exploit raw data from some exotic remote event. (smiles ;)
