[Meetings incl. Payload members] * Large meetings: before the next MMO-Design Meeting & MMO-SWG in May-June.

(with the update of “I-ICD FAQ” and “MMO-Payload Action Item List”)

[Electrical] * PSU might be independently prepared for the instruments outside of MDP. * Grounding Concept in MDP-2 : It will be fixed based on the EM test by PWI.

[Mechanical / Thermal] * Vertical style: It will be studied in detail in 2006FY.

[DPU] * SpaceWire I/F : Hardware design is progressed.

Test hardware (= E-GSE in future) is in development. * Software : Conceptual design is progressed.

[Development Schedule] *Schedule for MDP & Its I/F is updated.

Progress from Jan. 2006

*Action Items in 2006FY

1) Establishment of “MDP-Chassis concept” = “Vertical style”Development & Test of “MDP MTM” & “MDP-STM” in Apr-Sep 2006.

(No support from each payload team is requested at the moment.)

2) Establishment of “PCB” inside MDP-1 & MDP-2.Following matters will be updated & discussed after the MDP-STM test.

- Frame concept- Heat Path concept- Harness & Connector concept
