1. Utilization Planning Status CategoryCrew time (hrs)Comments Nominal Task92.74Maintenance task : 28.24 hrs (30.5%) Reserved Task45.60Maintenance task : 1.33 hrs (2.9%) Total138.34Maintenance Task : 29.57 hrs (21.4%) –Comparison with Inc33/34, and maintenance task takes higher percentage and it accounts for approximately 30% of nominal crew time. (The maintenance task accounts for around 2% in Inc33/34.) This is because the SpX-3 flight slip to Inc37/38 causes a reduction of experiment tasks. –The reserved crew time is 45.6hrs. However most of the crew task has prerequisite/conditions. It might be hard to use all the JAXA crew time allocation if HTV4 flight was slipped to the next increment or some JAXA payload facilities were down. Increment35/36 JAXA Utilization Plan Overview –In the latest JAXA utilization plan, the nominal crew time requirement is 92.74 hrs including about 28hrs of payload maintenance tasks.

2. PTP Blank Book –Purposal IDRD Annex5 (PTP table) covers a lot of requirement data items, and IPMs/IPEs make a lots of efforts to make and maintain this document. To reduce the efforts as much as possible, JAXA proposes restarting PTP Blank Book updates. As shown in JAXA comments in 2011, JAXA requested deleting all tables other than below. (Refer to JAXA comments in 2011 for details.) ・ Table3.0-7: Overview/Purpose/Constrains of each payload ・ Table4.1: Manifest ・ Table5.2-1 : Crewtime ・ Table5.2-3 : Resource request of Gas/ Water etc ・ Table9.1-1 : SSE table –Status 2011/4@MPMIT : Proposal of update PTP Blank Book 2011/5 : Sent back JAXA Comment 1 2011/8 : Sent back JAXA Comment 2 2011/8 : Sent back JAXA Comment 3 2011/10 : Sent back JAXA Comment 4 -> No Progress PTP Blank Book update

2. PTP Blank Book Payload manifest data input process –JAXA Proposal For manifesting Payload HDWs, change to inputting into MIDAS directly instead of submitting MR Loader. –Purpose /Background Under the current payload manifesting/changing process, MR Loader is required. However, for manifesting System HDWs, they are directly inputted into MIDAS. This is “OC process”. Recently, JAXA IPM transfer into JAXA Operation Management team, JEM Mission Operations and Integration Center (NASA OC counterpart). It means both NASA and JAXA IPM teams are under Mission Ops&Inte Office. Therefore, for payload HDWs manifesting, JAXA would like to apply the same manner as OC (System HDWs manifest process), and this process will save time for making MR Loader and reduce data inputting errors. With request from JAXA IPM Manager, JAXA would like NASA to consider this proposal. –Issue for NASA If there is any issue for JAXA proposal, we will have discussion for solving an issue.

3. Method of Crew time addition Standardizing a method of adding crewtime in the real time phase –JAXA Proposal In the real time phase, sometime planned crewtime is expanded by Houston FD’s order considering crew’s physical condition and so on. However, the method/process of crewtime padding to reduce crew work load is different in each increment. (e.g.) Inc 33/34: Additional 25% Crew time for first look task Past Increment : 5 min task -> 10min task Everytime in this situation, it takes a time for coordination among IPs. Therefore, we suggest making guideline of padding crewtime. –Future work The guideline of padding time need to be defined in GGR&C.

Crewtime estimation for NASA payload activities. –JAXA request About “Pad time” for Kevin, the Huston FD required us for adding 25% for first look crew task. We knew this padtime method was applied to only Kevin’s tasks. JAXA planned crew time already include pad time. This means the planned duration is always for the crew who assigned to the task for the first time. Therefore, it was not necessary to add “Pad time” to JAXA payload activities. At the same time, we thought the estimation method of crewtime might be different from NASA. Therefore, we want to know the way of NASA crewtime estimation. –JAXA method of crewtime estimation First activity: Based on the time performed by a stuff who never see the ODF and add a margin (considering under microgravity). For task performed in a previous increment: Based on an actual crewtime in a previous increment. 3. Method of Crew time addition (Cont’d)

Background & Purpose SSP 54504: Increment Definition and Requirements Document, Annex 5: Payload Tactical Plan Blank Book, Revision B was baselined in November 2007. Since that time - multiple updates to the blank book have been identified or proposed to make our Annex 5 documents match the way we currently do business. This presentation includes the consolidated proposals from all partner agencies for blank book updates.
