Since the Moon always keeps the same face towards the Earth wouldn't a "lunasynch" sat be at the L2 Earth-Moon Lagrange point? L2 is an unstable orbit, so sort of propulsion would be required to stay there. I wonder if it would be cheaper/easier in the long run to put the telescope on the Moon's surface? Nice explanation of Lagrange points: http://map.gsfc.nasa.gov/m_mm/ob_techorbit1.html Anybody know the distance from the Moon of the Earth-Moon L2? Would a sat Earth-Moon L2 ever be visible from the Earth?
