[SLS-CC] CS - restart of activities with end of US shutdown

Tue Nov 18 08:39:32 EST 2025

Hi all,
Thanks all for the feedback.

For re-starting activities, I would like to propose the following way forward:
                By December 15th:

-          Fall 2025 MoM (including already comments received so far) to be reviewed

-          All agencies, AI_25_09 to be completed
To provide system scenarios for Lunar missions, to be adopted for the system analysis (see AI_25_09). In particular, to provide:

?  -orbital parameters

?  -EIRP and G/T (relay and user)

?  -min. required data volume per pass (or minimum average data rate)

-          @Stefano Petri<mailto:Stefano.Petri at esa.int>/ESA, to please check completion of action AI_25_10 and inform WG

-          @Daniel Pettitt<mailto:Daniel.Pettitt at esa.int>/ESA to please check completion of action AI_25_12, and inform WG

-          All agencies, to complete AI_25_14
Member agency to check with vendor if they can be frequency agile in Ka-Band Lunar allocation with a resolution of 2 Hz

-          @Nicola Maturo<mailto:Nicola.Maturo at esa.int>/ESA to inform WG about completion AI_25_15 (I understand already completed)

-          All book captains of Pink/Red sheets to populate CWE folder https://tinyurl.com/CS-Draft-Documents as per below (see also what I did for LBDF pink sheets)

For the progress meeting on 2nd December, I propose to re-target it as Agency Review RID disposition of 131.0-P (for which RID deadline is 26 November)

Regards,

Andrea

Hi all,
Can NASA folks please let me know if activities can restart, now that US shutdown appears finished?
I will then propose new deadlines accordingly

Hi all,
Due to the US shutdown, AI deadline is postponed to TBD date.
As soon as activities restart, I will fix the new deadline at +15 days.

Same will be for comments to the MoM,

Andrea
