Progress in geophysical research enabled by InSAR methods has been tightly linked both to basic math and physics and to
technological advances throughout InSAR's 30 year history. Here we examine significant scientific
achievements using InSAR against the improved understanding of basic science and the technological developments that have
permitted new geophysical applications. Abstract mathematical and physical constructs such as network flow and a more
complete understanding of radar scattering have led to new algorithms such as phase unwrapping and persistent scattering
analysis. Fundamental advancements in technology, including digital data acquisition and processing, multichannel radar
systems, and the huge increase in computational power, have led to the ever-increasing set of questions that can be addressed
by InSAR remote sensing. Because of the long lead times required to put radar satellites in space, current technological
trends provide a good indication of the capabilities of future radar spacecraft for the foreseeable future. On the other
hand, predicting which existing analysis methods now used commonly in other branches of science will cross over to
geophysical applications and lead to scientific breakthroughs is nearly impossible, and thus we can only predict here that
many exciting results will follow as data from these spacecraft flow to ever-increasing numbers of scientists.
