Cover: An artistic impression shows the MUSES-C Hayabusa spacecraft approaching 25143 Itokawa (1998 SF36) next June. This half-kilometer-long near-Earth asteroid was the subject of radar observation from Goldstone and Arecibo planned during 17-22 June. It is reported in yesterday's Daily Orbit Update MPEC, and on the radar observations page as observed only June 17th with the 70m antenna at Goldstone in southern California. The illustration, courtesy of JAXA, may have been created before a shape model was available from radar observing during a 23-day period in early 2001 (see the A/CC June 26th cover).
