NASA's New Exoplanet Hunter Is Using a Clever Orbit

Summary TESS, the new satellite that will follow up Keppler in the search for exoplanets, had a tight budget that required some unusual optimization. In particular its orbit is designed to minimize fuel requirements. So it used a lunar gravity assist to put it in an eccentric orbit of the earth to provide fast data transfer at perigee and avoid eclipses by the earth of its field of view. And it is 90 degrees out of phase with the moons's orbit to keep the orbit stable.
