3. Page No. 3 Operations Concept Review  STP provides overall Operations Management role  Complement of 4 payloads operate from remote POCCs – DISC operates from Naval Research Lab in Washington, DC – VADER operates from Air Force Research Lab in Albuquerque, NM – MHTEX operates from Northrop Grumman in Redondo Beach, CA – Canary operates from US Air Force Academy in Colorado Springs, CO – STP operates from Johnson Space Center in Houston, TX  Single command window – Individual payload commanding sequentially within command window  Flexible payload order and duration – Special payload specific 8 hr command windows arranged via OCR – Initial 6 week checkout period 8 hrs x 7 days a week – Continuous Operations 4 hrs x 5 days a week for 1 year or less  Use IVoDS, EHS and TReK workstations for voice communications, planning, commanding and telemetry – MHTEX and DISC have local TReK workstations – VADER & Canary use a remote Virtual Machine server setup by STP to access TReK and EHS resources – STP commands on an as needed basis

4. Page No. 4 Initial Operations Timeline Activation Phase Canary Special Command Window for baseline and PCU data take MHTEX Special Command Windows to adjust Heaters (not cmd intensive) Initial Video Survey using SSRMS before it moves off worksite Daily Internal Tagups to coord and obtain status first four days after install Standard Command Window Flight Plan STP-H3 Activities

5. Page No. 5 Payload Activities during the first few days  Activation (STP performs functional checkout) – After ELC installation, ELC/ExPA RPC is turned on (PRO command), SIU and TCM receive power  SIU Health & Status data starts flowing  VADER temperature analogs start flowing (not through SIU) – ISS discrete (PRO command) required to apply power to TCM heater relays – Functional test of STP-H3 is conducted (~75 commands) may take 8 hrs to complete on-orbit  Initial SSRMS Survey of STP-H3  MHTEX – Cooling loops required to be primed prior to operations – Requires “tweaking” heaters to  Ensure vapor spaces are cleared  Ensure condenser is not overdriven  Will request special 8 hr MHTEX Command windows (Priming 1 and 2) in addition to standard command window for 3 days to tweak heaters when necessary (not command intensive) – Survey of radiator surface

6. Page No. 6 Payload Activities during the first few days  DISC – Turn on and monitor temps – Verify DISC shutter is operational – Acquire and download a star field image – Download Optimization Test – Survey of DISC lens  Canary – Bake-out period satisfied by first day on-orbit – Functional tests and Calibration of download data – Activation prior to Plasma Contactor Unit turn on FD4 (sleep period)  Need baseline prior to space environment modification – Survey of Canary field-of-view and face  VADER – Command windows to tweak heaters and VEDs – Monitor temperature deltas and rates – Monitor temperatures on/around Aerogel MLI – Survey of front face, VED area and backside blanket

7. Page No. 7 MHTEX Primary Objectives  Objectives for new components should be met in first 4- 8 weeks  Goal to flight qualify the advanced capillary pumped loop system – Demonstrate a fully reliable startup and continued operation under normal expected operating conditions – Demonstrate heat pump functions as intended under varied thermal loading conditions – Investigate functionality of the advanced evaporator pump for application to a next generation CPL design  Achieve a steady state operation mode for ~336 hours (~ 2 weeks)

8. Page No. 8 MHTEX Alternate Startup Test and Secondary Objectives  Alternate Startup Test – Test will be performed once primary objectives are satisfied but before secondary objectives – Use the advanced evaporator instead of the starter pump to start the system – If it does not then the system will be re-primed and move on to secondary objectives  Secondary Objectives – Demonstrate a steady state operation mode throughout the remainder of the one year of operations – Modes will be modified to test varied thermal loading throughout the year – Commanding is expected to be much less intensive than the first 6 weeks of activation and checkout

9. Page No. 9 DISC Primary Objectives  Successful initial checkout of DISC camera – Acquisition and downlink of initial DISC image  Command & Data interface and verify camera electronics – Verification that DISC shutter is operating  Successful acquisition and downlink of one star field image – Done on FD13 or after Shuttle undock to acquire image in the normal ISS attitude  Successful correlation of ISS position with DISC aspect solution – Downlinked ISS data stored within the ODRC repository will be used for the ISS position truth data

10. Page No. 10 DISC Secondary Objectives  Acquire and downlink one star field image or a series weekly after FD13 – Correlate ISS position with DISC aspect solution – Verify ability to change DISC image acquisition settings by acquiring and downloading an image in each mode  Acquire and downlink of a series of star fields during a single orbit  Successfully correlate DISC aspect solution from a series of images acquired during the same orbit over time with the ISS attitude solution  Acquire and downlink a long integration DISC image  Determine ISS drift rates via long integration DISC image  Determine DISC limiting magnitude sensitivity  Long term characterization of star camera operation and performance over a 1-year period

11. Page No. 11 Canary Primary Objectives  Successfully complete functional checkout  Successfully complete calibration file download  Obtain and downlink a baseline of the space environment around ISS – Within current timeline this is best done prior to Plasma Contactor Unit activation but is not considered invalid if delayed  Obtain data from the Space Shuttle ISS re-rendezvous activity (STORRM DTO) – Multiple Space Shuttle jet firings are expected within close proximity to the ISS making it an ideal data collection for Canary Science – Space Shuttle has the most obtainable as-flown data

12. Page No. 12 Canary Secondary Objectives  Collect data from the relocation, docking and undocking of any ISS visiting vehicles  Collect data from an ISS Reboost Event  Collect data from the Plasma Contactor Unit operation  Collect data from other contamination events – Ammonia Leaks – Debris Avoidance Maneuvers – EVA/EVR activities – Payload venting through Vacuum Exhaust System – Water Dumps

13. Page No. 13 VADER Primary Objectives  Successfully complete functional checkout  Collect initial emissivity data for each state (colored and bleached) to verify switching capability and establish a baseline – Done by thermal cycling VEDs in colored and bleached states  Collect Aerogel temperatures to determine the thermal insulation capability  Increase cycles on VEDs to at least 100 (bleach-color=1, color-bleach=2, etc)  Obtain imagery from SSRMS Survey at one month on- orbit timeframe

14. Page No. 14 VADER Secondary Objectives  Further increase cycles (switching between modes) on VEDs as much as possible to simulate on-orbit lifetime  Collect lifetime switching at 1 mo, 3 mo, 6 mo, 1 year  SSRMS imagery will help with lifetime durability of both the aerogel material and electrochromic materials – SSRMS surveys include initial, one month then every 6 months

15. Page No. 15 Continuous Operations Phase  Begins after 6-week initial checkout period  Command Windows 4 hrs Mon to Fri  Canary and DISC to request special command windows to collect data – Standard command windows can be used to download data  SSRMS surveys every 6 months until STP-H3 deactivated  MHTEX – Demonstrate a steady state operation with varying modes throughout the remainder of the one year of operations  DISC – Each week acquire & downlink images to satisfy secondary payload objectives  Canary – Collect data from visiting vehicles and contamination events throughout the remainder of the one year of operations  VADER – Cycle through bleach & color modes throughout the one year on-orbit – SSRMS surveys will help with lifetime durability of aerogel and electrochromic materials

16. Page No. 16 Questions 1. When does STP need to submit OCRs for special command windows that occurred during the first week of ULF-6 mission (and entire docked phase)? – MHTEX priming – Canary data takes  PCU act, 41P Undock, ISS Reboost (potential), 42P Dock and STS-134 Shuttle STORRM DTO – DISC first star field image (after Shuttle undock) 2. Will POIC maintenance be suspended during docked phase of ULF6 mission? 3. During Activation and Checkout period can the PRO record commands sent to a log file (including HEX values) for potential troubleshooting purposes? 4. Does OC & PRO use the same PD Call List? Where can we review this information? 5. With 41P undock and 42P dock planned to occur while ULF-6 docked as well (involves DC-1 on MLM). Will the ISS attitude be changed for these events or does the approach change for these Progress vehicles or being Nadir everything is as usual?
