I draw and paint mostly about Mars exploration, but also about flight, polar and space exploration, prehistory, and disasters. I often use my own drawings and paintings to illustrate my talks and publications.
I strive for realism, scientific and technical, in most of my drawings and paintings. I attempt to create visions as they would appear to a human explorer on site. I allow the scenes depicted to be imaginary, but endeavor to make their representation realistic, as if actually experienced. My goal is to transport the viewer to another world, to make him/her a front row witness to a unique moment in space and time.
