Pole sitting was a fad in the United States in the 1920s, but ESA is putting a modern orbital spin on the practice. Investigating advanced orbital mechanics, the space agency has concluded that it's possible to build a hybrid solar-sail/electric-propulsion satellite that could hover over either of the Earth's poles by balancing the pull of the Earth and the Sun.
