ACE Weekly 10/19/2010 - 10/25/2010 All ACE spacecraft subsystems are performing nominally. ======================================================================== Orbit/Attitude: No maneuver was completed this week. The next attitude maneuver is scheduled for Thursday 10/28/2010. ======================================================================= OCRs: None ======================================================================== Activities: Data Capture: 100% DOY 290-297 2010 There is a higher than normal risk of data loss from October 2010 through February 2011. If there are problems with the passes, it may not be possible to acquire additional DSN time. ======================================================================== Anomalies: DOY 294 10/21/2010 S-ACE-0551 G10-0067 ANSR notifications not received ANSR notifications were not received by FOT throughout the support. On-Call Engineer went to MOC and confirmed pass activities were executing nominally. MMOC System Administrators (SAs) notified. Analysis showed while ANSR was contacting the mail server, an error was preventing ANSR notifications from being sent. In addition, SAs discovered a file permission issue had caused ANSR's logging mechanism to crash, thus preventing further analysis of the ANSR error. File permissions were modified and ANSR recycled. FOT began receiving notifications. IMPACT: FOT monitored support activities real-time. DOY 295 10/22/2010 S-ACE-0549 G10-0065 DSS-27 Power Outage D27 experience a power outage 90 minutes into ACE's support. Telemetry offline for remainder of support. (DR#N106665) IMPACT: No data or commands for 120 minutes. No data to NOAA Space Weather Prediction Center (SWPC) for 120 minutes. Manual intervention required to complete pass activities. All data recovered during SSR playbacks on subsequent supports. DOY 297 10/24/2010 S-ACE-0550 G10-0066 IONet Mail Server Down MMOC team stopped receiving notifications following DOY 296 support. On-call Engineer came in on DOY 297 to assess status of the pass once nominal BOT notifications were not received. Once pass activities confirmed nominal, ACE Engineer notified MMOC team that notifications were not being issued. IMPACT: Unable to monitor Pass activities. Delayed FOT response if an anomaly had occurred during DOY 297 support. IONet Mail Server back up prior to start of DOY 298 ACE support. ------=_NextPart_000_0037_01CB75D2.E4E8E000 Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN"> <HTML> <HEAD> <META HTTP-EQUIV=3D"Content-Type" CONTENT=3D"text/html; = charset=3Dus-ascii"> <META NAME=3D"Generator" CONTENT=3D"MS Exchange Server version = 08.00.0681.000"> <TITLE>ACE Weekly 10/19/2010 - 10/25/2010</TITLE> </HEAD> <BODY> <!-- Converted from text/rtf format --> <P DIR=3DLTR><SPAN LANG=3D"en-us"><FONT FACE=3D"Consolas">ACE Weekly = 10/19/2010 - 10/25/2010</FONT></SPAN></P> <P DIR=3DLTR><SPAN LANG=3D"en-us"><FONT FACE=3D"Consolas">All ACE = spacecraft subsystems are performing nominally.</FONT></SPAN></P> <P DIR=3DLTR><SPAN LANG=3D"en-us"><FONT = FACE=3D"Consolas">=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D</FONT></SPAN></P> <P DIR=3DLTR><SPAN LANG=3D"en-us"><FONT = FACE=3D"Consolas">Orbit/Attitude:</FONT></SPAN></P> <P DIR=3DLTR><SPAN LANG=3D"en-us"><FONT FACE=3D"Consolas">No maneuver = was completed this week.
