No problems encountered. The DSN schedule is a bit tight at the end of October and beginning of November 2013. LADEE will launch Sept ~7 and ISRO's Mangalyaan (Mars Orbiter Mission) will launch Oct ~21. Depending on launch slips and antenna availability, ACE will utilize WS1 as possible. Note that the new moon is November 3, which portends LRO using WS1 during the day when WS1 would have view of ACE. ======================================================================== Anomalies: None
