Ongoing Activities:

Space Link Extension (SLE) - ACE SLE version 2.1 was delivered to the
Library on April 28, 2006.  The delivery to the ACE MOC will not be until
after String 3 is converted to the RIONET.  

RIONet - String 3 conversion to the RIONet is on hold based on NASCOM's
schedule.    

Attitude Training - The FOT continues training on attitude determination,
maneuver planning, and maneuver execution.

Extra Activities:

DOY 122 (05/02/06) - Scrolled through all 30 telemetry section for SSR-B.
No new errors were detected on the SSR.

Anomalies:

DOY 121 (05/01/06)  G06-0044  Command Retransmission
Multiple commands throughout the pass needed to be retransmitted to the
spacecraft.  JPL was also sending multiple command echos for the commands
back to the MOC.  The command and command echo problems were due to an
unknown problem at JPL that was affecting a other missions as well.  DR
N103611.
IMPACT:  Commands needed to be retransmitted.  Duplicate command echos
received in the MOC.

DOY 121 (05/01/06)  G06-0045  DSS-24 - Transmitter Problem
The transmitter at DSS-24 tripped due to problems with their Heat Exchanger.
DR G106681.
IMPACT:  Lost command uplink for about 25 minutes.
