I am a consulting physicist in Vancouver (Canada) and enjoy tough problems and limited budgets. I operate a consultancy that has addressed a wide and varied range of topics in the last eight years and am a reformed rocket scientist. For ~20 years I worked on planetary spacecraft missions for the European Space Agency and NASA, authored a few dozen papers and contributed to a couple of textbooks.
