PI: Dr. Mark R. Showalter SETI Institute CoI: Dr. Jack J. Lissauer NASA Ames Research Center N CoI: Prof. Imke de Pater University of California - Berkeley N CoI: Dr. Richard G. French Wellesley College N ------------------------------------------------------------------------------------ Abstract Nine densely-packed inner moons of Uranus show signs of chaos and orbital instability over a variety of time scales. Many moons show measureable orbital changes within a decade or less. Long-term integrations predict that some moons could collide in less than one million years. One faint ring embedded in the system may, in fact, be the debris left behind from an earlier such collision. Meanwhile, the nearby moon Mab falls well outside the influence of the others but nevertheless shows rapid, as yet unexplained, changes in its orbit. It is embedded within a dust ring that also shows surprising variability. A highly optimized series of observations with WFC3 over the next three cycles will address some of the fundamental open questions about this dynamically active system: Do the orbits truly show evidence of chaos? If so, over what time scales? What can we say about the masses of the moons involved? What is the nature of the variations in Mab's orbit? Is Mab's motion predictable or random? Astrometry will enable us to derive the orbital elements of these moons with 10-km precision. This will be sufficient to study the year-by-year changes and, combined with other data from 2003-2007, the decadal evolution of the orbits. The pairing of precise astrometry with numerical integrations will enable us to derive new dynamical constraints on the masses of these moons. Mass is the fundamental unknown quantity currently limiting our ability to reproduce the interactions within this system. This program will also capitalize upon our best opportunity for nearly 40 years to study the unexplained variations in Uranus's faint outer rings. ------------------------------------------------------------------------------------ Observations Description ------------------------ Astrometry of the Uranian satellites is accomplished via eight visits, each consisting of a sequence of long exposures through the broad F606W filter. Each orbit begins with one unsaturated image of the planet for geometric reference and calibration checking. The orbital plane is oriented within 20 degrees of the X-axis in the images to separate the moons from the wide vertical band caused by saturation bloom from the planet. From orbit to orbit, Uranus is shifted upward and downward by ~ 40 pixels within the 512x512 subarray to achieve some of the benefits of dithering; however, moons can always be distinguished from hot pixels by their motion. Each visit is timed to place one of the smallest moons near its maximum orbital elonagation, because this is where such moons are most detectable. The larger moons will be captured by 12245( 7) - 20-Oct-2010 13:57:46 - [ 2] chance and require no special targeting. Mab is the target of repeated observations in order to study its orbital variations. A ninth visit will be used to determine the color of Mab and that of its neighboring moons, Puck and Miranda. With measurements spanning blue to the IR, it will be possible to determine which of the two neighbors most resembles Mab, and thereby reduce the large uncertainties in Mab's albedo and size.
