Carbon dioxide frost consigns Phoenix Mars Lander to history - Oneindia News
According to McEwen, it gets so cold during the Marian winter that carbon dioxide, which accounts for 95 percent of the planet's atmosphere, forms a frost blanket up to one or more feet thick that covers the entire northern landscape each winter, including any spacecraft that might be on the surface.
"The Mars Lander's solar panels were not designed to withstand significant loads of such carbon dioxide frost," said McEwen.
