I updated the target ephemeris for visit numbers 4, 5, and 6. They all use target #3, which uses orbital elements from MPEC-F15. ----- Attempting Submission 5 (Thu Mar 25 18:17:41 GMT 2010) ----- The target for visits 4, 5, and 6 have been updated to use orbital elements from MPEC-F15. No other changes were made. Our Director's Discretionary program (GO-12053) to image the newly discovered object P/2010 A2 executed successfully on 2010 Jan 25 and 29 with spectacular results. Hubble has apparently borne witness to the first detection of a collision in the asteroid belt. Hubble imaging with the WFC3 has revealed an object unlike anything ever seen before and with details impossible to detect with any other facility. We request 6 more orbits of Hubble time (1 orbit every 20 days over the next few months, until the object enters Hubble's solar exclusion zone in late-June 2010) to monitor the evolution of this remarkable object and further clarify the nature of this event. These observations may usher in a new era of searching for and characterizing collisional events within the asteroid belt.
