<DIV dir=ltr><FONT size=2 face=Arial>We have given the official 'Go' for the orbit maintenance maneuver procedure. We will begin on Sunday, June 5th by repointing to align the spacecraft with the velocity vector at apogee. After pointing is approved we will spin up to 22rpm for spin stabilization during the delta-V maneuvers. </FONT></DIV>
