The 2016 campaign began on 06/07/2016. - OSIRIS-REx (ORX) was scheduled to launch 09/08/2016. Several ACE DSN supports were impacted by the proposed launch contingencies. The return to the 9 degree upper limit antenna constraint allowed ACE to resume operations with WS1. - WS1 supports scheduled for 9/14/2016, 9/15/2016 and 9/19/2016. ======================================================================== Activities: Data Capture: 100% 2016 DOY 242 - 2016 DOY 254 ======================================================================== Anomalies: None =========================================== Jacqueline Maldonado Snell WIND, Geotail and ACE Flight Operations Team Manager Honeywell Technology Solutions Incorporated (HTSI) Goddard Space Flight Center Bldg. 14 Rm N284, Mailstop 428.2 Greenbelt, MD 20771 Office: 301-286-7072 Cell: 443-896-8868 Fax: 301-286-8257 Email: Jacqueline.M.Snell@nasa.gov
