Hi all,

	Mike T. needs us to forecast any NSF BCPs needed through June 2025.	He 
would like to keep the list short, so we should include only BCPs that 
are really needed before July.
	For the FEB2 (6.4.2), I don't see any coming soon. I need to hear asap 
from Tim and Andy any they see coming soon in their L3 area.  I attach 
for reference the recent Scrubbing Report.  Some comments:

6.4.1
- the ADC "production complete" milestone for UT Austin is currently 
05-Jan-26, so presumably no need to change soon?
- the SMU work was just approved through end September, so we can 
postpone the next BCP until July-August (ie. later than June)

6.4.3
- we learned this week the LASP is now aiming "tentatively" for an FDR 
around Feb. 2026.  Our current SRTM FDR date is set 25-JUL-25.  So 
presumably this will have to change?  And if so when do you want to 
change it?
        A couple more notes:
		- If we need to change it by 6-7 months, the SRTM will take over the 
Critical Path again (since it is currently ~4 months ahead of the FEB2).
		- we currently have 205 (162) days float in the Baseline (Working) 
schedule, compared to 90% CL need from MC of 137 days. If we introduce 
now 120-140 days of delay, we will be back in negative float, just in 
time for the NSF review in July.  I think that could prove quite 
problematic at the review.
		- I am also concerned about the BCP cost if, like for previous SRTM 
delays, we extend all the firmware labor to keep its end date aligned 
with the SRTM hardware.

	Andy/John H. should take a look and see what would make sense.  If we 
want to delay the July date, we would need to have the BCP by May, 
meaning it should go on Mike's list now.  We might consider for now 2 
options to compare:

1. delay by 4 months, extending only SRTM work (this would be smallest 
request)

2. delay by 6-7 months, extending SRTM + f/w (this would be largest request)
        
        Regards,
                John

Hi NSF L2 managers,

In talking with the NSF, we need to resolve a “bookkeeping” issue (my 
view)regarding what NSF calls the “Contingency Balance” [if you 
diligently read the NSF monthly report you will find that in Table 5 😉] 
. You will see that in January it turned negative (~-$1.7M), which at 
this time NSF does not like to see, they want that number to be 
positive. We need to provide them with the expected use of contingency 
beyond what we reported in January (through BCP-1102, not including 
1101). So I need from you:

 1. Your best estimate for BCPs that would be submitted through June
    2025 – if possible please indicate a date by which you would submit
    the BCP. If some can be delayed beyond that date, please do that as
    I would like to keep the number smaller as it will be easier for NSF
    to swallow
 2. Please include (a) estimated $ amount  (your best guess), (b) what
    WBS #, (c) one line description
 3. Due COB March 6 – the sooner we get this in the better given the
    looming Continuing Resolution deadline of March 14

Thanks, Mike
