All,

    The spacecraft is nominal, and the inertial maneuver was successful. We did have an issue with commanding during the contact. The station was able to lock up on data with no uplink at AOS. But when we brought up the command carrier the station was unable to lock back up on the downlink. SSC worked the issue for a few minutes. We then decided to just leave the carrier down and monitor the spacecraft SOH data. Because of this we will not have any tracking data for this USHI02 contact. SSC has notified their engineers and they are looking into the issue.
