Guys,
  Here are the planning files for Orbit# 155.
Please respond to this email link for all approvals/comments which are due 
by 24 Jan 12 @ 1800 UTC
 
 
 
1. Command Load Constraint Violations:
 
SOFT CONSTRAINT VIOLATIONS
==========================
IBX-CLC-008: Spacecraft state is HK during interval 2012/02/04 09:15:20 
UTC -
             2012/02/04 09:29:06 UTC, which overlaps HVSCI payload mode at
             2012/02/04 09:15:20 UTC - 2012/02/04 09:29:06 UTC
IBX-CLC-008: Spacecraft state is HK during interval 2012/02/04 09:29:06 
UTC -
             2012/02/08 10:40:48 UTC, which overlaps HVSCI payload mode at
             2012/02/04 09:29:06 UTC - 2012/02/08 10:40:48 UTC
IBX-CLC-015: Battery charge falls below minimum from 2012/02/04 03:37:00 
UTC -
             2012/02/12 21:24:23 UTC. Lowest charge level is 0.000000
             watt-minutes during this interval.
 
*  The previous command load ended after 10_re ascending because a contact 
straddled the 10_re ascending mark.  The contact was orginally planned at 
9_re ascending and moved closer to the mark because of the EPH time shift.
The time start for this ATS is at 4 Feb 12 @ 0338 UTC anf the 10_re 
ascending commands occur before MPS recognizes them and gives the errors 
listed above.
  I will change all existing contacts that are close to the 10_re mark to 
stop this from happening in the future.
 
*  The battery charge levels will remain until we find a fix in MPS 1.4 or 
dump the history timeline.   
MPS 1.4  shows a pre-warm long eclipse heater that has been on since 
Orbit# 152, but commands were not sent and the heater is not on.  The 
eclipse commands were sent via ABS in the command builder.
The problem is currently in review.
