ACE Weekly 04/27/2007 - 05/03/2007

All ACE spacecraft subsystems are performing nominally.

============================================================================
Orbit/Attitude:

No maneuvers were completed this week.  The next attitude maneuver is
scheduled for Thursday, 05/10/2007.

============================================================================
OCRs:

DOY 123 (05/03/2007)  GND-180  OpenSSL & Crypt-SSLeay for FD Products
Flight Dynamics will be providing ACE products on the FD Product Server
(https).  OpenSSL and Crypt-SSLeay are necessary for simplifying the
download process.  OpenSSL has been installed, Crypt-SSLeay will be
installed when it is available.

============================================================================
Activities:

RIONET - String 2 conversion to Restricted IONet has been scheduled to start
5/8/2007.

Space Link Extension (SLE) - ACE SLE version 2.1 was delivered to the
Library on April 28, 2006.  Installation in the ACE MOC will not occur until
after the MOC is converted to the RIONET.

Two issues have been found with DSN SPS viewperiod generation.  1) ACE
viewperiod files are being generated to start 5 weeks in the future and 2)
ACE viewperiods are not using the latest ephemeris.  DSN is reviewing their
processes and has requested that Flight Dynamics change the generation of
ACE ephemeris data.  A telecon had been scheduled for 4/30/2007, but has
been postponed.  The telecon has not been rescheduled.

An evaluation is ongoing to replace the TPOCC mission software and
incorporate ACE operations into a multi-mission ops center.  A decision
between L3 INCNG and ITOS mission software is expected soon.

============================================================================
Anomalies:

DOY 121  05/01/2007  S-ACE-0174  G07-0033  Printer failure
A stuck print job on a backup workstation prevented all workstations from
successfully printing to the network printer.
IMPACT:  Time and effort troubleshooting problem.
