 And by the way, is it always imagery within the visual, human visual spectrum, or are there other areas of the spectrum where, because these things are small and moving so fast, they can be detected other than visually? That's a great question. These pieces of debris can be detected with radar and LiDAR and other things outside of the optical regime. In fact, one of the main ways debris is currently tracked is from the ground with radar. The reason we're working with optical sensing is
