Guys,
  Here are the planning files and ATS for Orbit# 170.
Please respond to this email thread with comments/approvals.
All comments/approvals are due before 8 June 12 @1200 UTC.
 
Please note the following issues:
1.  Orbit# 170 Long Eclipse:  MPS Generated Eclipse Commands are DELETED 
in this ATS(v002)
         # 
2012-06-19T07:07:20.217Z,EclipseEntry,orbit:170,moderate:false,long:true
         # 
2012-06-19T09:50:45.031Z,EclipseExit,orbit:170,moderate:false,long:true  
2. Long Eclipse Flag Timing
         # 
2012-06-19T07:07:20.217Z,EclipseEntry,orbit:170,moderate:false,long:true
         # 
2012-06-19T09:50:45.031Z,EclipseExit,orbit:170,moderate:false,long:true  
       @ECT_SetLongEclipseFlag TRUE $TIME=2012/06:19:05:37:00 (90 minutes 
before start of the eclipse)
        @ECT_SetLongEclipseFlag FALSE $TIME=2012/06:19:15:07:00 (8 hrs 
after the start of the sclipse)
3. ==========================
SOFT CONSTRAINT VIOLATIONS
==========================
IBX-CLC-015: Battery charge falls below minimum from 2012/06/19 09:27:20 
UTC -
             2012/06/19 10:19:00 UTC. Lowest charge level is 69.177923
             watt-minutes during this interval.
##  Normal ops load shed threshold is 3.6V
     When the long eclipse flag is set, the threshold is reduced to 3.1V
    If Load Shed 1 threshold is crossed, the spacecraft will enter 
Contingency State.
    If Load Shed 2 threshold is crossed (lower voltages, 3.4V if long 
eclipse flag is not set) the spacecraft
    will autonomously do a sun pointing maneuver to find the sun and 
charge the batteries.
 
 
 
IBX-CLC-016: Science enable-to-spin pulse protection enable interval is 
longer
             than the maximum allowed 300.000000 seconds for the times
             2012/06/19 15:17:45 UTC - 2012/06/22 16:35:14 UTC 
(263848.969000
             seconds). 
##  The MPS Long Eclipse wrote does not include the  command to enable the 
spin pulse protection command.  The command is 
generated by the STF file.
