Revised to change from ACS to WFPC2 consistent with submitted PCR. ----- Submission 1 (Thu May 18 20:46:28 GMT 2006) ----- ----- Submission 2 (Tue Sep 05 22:48:19 GMT 2006) ----- ----- Attempting Submission 3 (Fri Mar 02 15:47:52 GMT 2007) ----- Assigned ID: 646 ----- Submission 1 (Sat Jan 28 00:39:44 GMT 2006) ----- Rotational state and composition of Pluto's outer satellites We propose an intricate set of observations aimed at discovering the rotational state of the newly discovered satellites of Pluto, S/2005 P1 and S/2005 P2. These observations will indicate if the satellites are in synchronous rotation or not. If they are not, then the observations will determine the rotational period or provide tight constraints on the amplitude. The other primary goal is to extend the wavelength coverage of the colors of the surface and allow us to constrain the surface compositions of both objects. From these data we will also be able to significantly improve the orbits of P1 and P2, improve the measurement of the bulk density of Charon, and search for albedo changes on the surface of Pluto.
