Ø On March 28, the 34 Soyuz vehicle with the Expedition 35 Crew launched from Baikonur. Approximately 6 hours later the Crew docked to the ISS. This was the first crewed 4-orbit rendezvous to the ISS. Ø From the USOS perspective, docking timeline is essentially identical for either rendezvous Ø System configurations (powerdowns, array positioning, attitude control handover) occur at same time relative to docking and are identical to any other Soyuz Ø No changes to joint Flight Rules or USOS procedures for the 4-orbit rendezvous Ø U.S. and Russian flight control and engineering teams have performed standard analysis for both 4-orbit and 34-orbit dockings Ø Soyuz generically retains enough propellant margin to support a re-rendezvous after an abort from any point in the trajectory

3 4-Orbit Rendezvous

Ø On February 21, 2013 the ISS Program conducting it Stage Operational Readiness Review and on March 6, NASA conducted the Flight Readiness Review Ø Included detailed review of all aspects of 4 orbit Rendezvous Ø Vehicle configurations / timelines for 4 and 34 orbit Ø Crew fatigue and health management Ø US and RS doctors approved a sleep shifting profile to align with launch / docking activities. Ø Crew activities post ingress were limited to the Safety briefing. Ø Space Adaptation Syndrome – discussed with combined US / Russian medical team. Ø Mitigated with experience crew members, preflight testing of medications, and the availability of these medications to the crew on day of launch. Ø Confined space / spacesuit issues Ø crew was allowed to ingress the Orbital Compartment for hygiene and food / water access. Ø MAGs were approved and available to all crew members Ø Crew able to loosen straps on-orbit to allow stretching and mitigate join pain. Ø Ø The ISSP and then the FRR Board approved the 4 – orbit for 34S only. Ø Plan is to conduct post flight lessons learned from vehicle, ops, crew, and medical teams to understand fully the risks and to determine if 4-orbit rendezvous should be approved in the future.

Ø Photovoltaic Thermal Control System (PVTCS) 2B Ammonia Leak - Monitoring Ø In 2007 it was confirmed that the Channel 2B PVTCS exhibited a relatively constant leak rate of ~1.5 lbm/ year that later accelerated to between 5.8 and 9.5 lbm/year by late 2012. USOS EVA 20 was performed on 11/1/12 to isolate the 2B Photovoltaic Radiator (PVR) and provide cooling via the Early External Active Thermal Control System (EEATCS) PVR via jumpers. Trending has confirmed that the isolated 2B PVR is not leaking. The new combined (hybrid) system is operating nominally. However, initial behavior suggests that the hybrid system is leaking and characterization of the rate is underway. Data to date indicates a rate in the range of ~5 lbm/yr, but many months are required to develop a reliable trend.

Ø Sequential Shunt Unit (SSU) 1A Power on Reset (POR) - Monitoring Ø On 1/10/13, SSU 1A started experiencing PORs during insolation passes, with this series of PORs ending on 1/13/13. Previously SSU 1A had experienced 3 other PORs. The impact from these PORs has been minimal. When the SSU performs a POR, the primary power channel momentarily goes to battery power (approx 1.5 seconds). Data gathering activities were developed that could assist the team in characterizing the issue if the PORs start re-occurring. The SSU will be operated as is while specialist continue their investigation through a similar solar beta period in March. Should the SSU have a hard failure, the Flight Control Team will perform the Seamless Power Channel Handover procedure to continue providing power to the loads on this channel.

Ø Ku-Band Antenna Group 2 (AG2) Forward Link Anomaly – Troubleshooting Ø On GMT 351, the Ku-band Group 2 failed to acquire TDRS. The Ku-band was configured to open loop pointing, with success in acquiring the return link, but not the forward link. Ku-band swapped to Antenna Group 1, acquiring TDRS nominally. Antenna Group 2 is currently powered off, with heaters enabled. Root cause identified a suspect failure in the Space to Ground Transmitter Receiver Controller (SGTRC). A spare SGTRC is available on-board. Removal and replacement is planned for US EVA #21 in June ‘13.

12 USOS System Challenges

Ø Loss of Columbus Water Pump Assembly (WPA2) - Monitoring Ø On 1/13, ESA was not successful in switching the active Internal Thermal Control System pump from WPA1 to WPA2. The switch over is a nominal activity in support of WOOV cycling conducted on a 3- month interval. Attempts to start WPA2 were unsuccessful, so the Columbus module is operating on WPA1 with no redundancy. Engineering evaluation of the fault is in-work, but the cause of the anomaly is not understood yet. A coolant top-off was performed on 2/14/13 to accommodate coolant sampling as well as margin for nominal leakage. There is no spare WPA on-board. A spare is scheduled to launch on ATV4.

Ø Increased N3 Common Cabin Air Assemblies (CCAA) Indications - Workaround Ø Water carryover events due to degraded heat exchanger (HX) in N3 CCAA. No spare CCAA HXs on orbit; one targeted for manifesting on HTV5. Ø FR Waiver in work to increase time prior to Carbon Dioxide Removal Assembly (CDRA) command to standby in the event of a continuous wet indication

13 USOS System Challenges

Ø MERLIN2 Shutdown Due to False Fire Alert - Troubleshooting Ø Event believed to be a result of a radiation hit on this system (Station at high latitude). MERLIN 2 used for galley food storage and has remained unpowered. Procedure in work to check the current system status after power up.

Ø Space Acceleration Measurement System II Remote Triaxial Sensor/Drawer 2 (SAMS-RTS/D2) Loss of Health and Status – Troubleshooting Ø On 2/11, SAMS-RTS/D2 lost health and status. Log files show no communication between SAMS and ICU. Troubleshooting isolated issue to either ER4 PEHB or JAXA LEHX. MART identified additional troubleshooting steps to be performed on 3/26 to isolate to one of these two systems.

Ø MBSU 2 RBI 5 Trip (feeds Russian Segment Service Module [CHT] 21 & 22) – Troubleshooting Ø Noise from the [CHT]s is believed to have caused MBSU2 RBI5 to trip off on GMT 206. Team developing procedures to use on-orbit oscilloscope to test the input side of the [CHT]s in the April/May timeframe.

14 USOS System Challenges

Ø Dragon Draco Thruster Check Valve Ø During the SpX-2 mission, 3 of 4 propulsion manifolds were not properly pressurized following second stage separation. The issue was overcome real-time and SpaceX has identified root cause due to failure of in-line check valves. SpaceX is working design modification for follow-on missions Ø During approach and release/departure, 3 of 4 quads are required to complete operations. An abort to protect ISS requires 2 of 4 thruster quads to be operational. Analysis has shown that Dragon will safely drift away from ISS in the event that all four quads failed Ø Although check valves operated nominally upon entry into ISS ellipsoid, sufficient blowdown was available should an abort be required Ø Check valve operated nominally for departure and re-entry

Ø HTV3 Abort Ø The HTV3 abort was caused by an interaction between the grapple fixture cam arms on the vehicle and the initial motion of the SSRMS during back away due to the relative positions of the HTV and the ISS. This interaction created rates on the HTV vehicle that, when checked on board the HTV, indicated the HTV would leave its designed departure corridor and thus it initiated an abort per joint safety requirements. Ø No damage was done to the ISS. NASA has assessed a number of options to eliminate this interaction to mitigate risk of an abort on future vehicles and is implementing a modified SSRMS release approach to incorporate a delay in the start of initial SSRMS back away. Implementation is on schedule and includes refining visual cues for the crew to monitor the release as well as potentially adjusting SSRMS configuration parameters to provide a smooth separation between the SSRMS and the vehicle. Ø NASA has assessed other free flyer vehicles (Dragon and ) and has implemented a corresponding approach to mitigate the concern. 15 Comparing Boeing 787 Li-Ion Battery to ISS Li-Ion

20 USOS System Enhancements

Ø In an effort to increase the utilization of Commercial off the Shelf (COTS) hardware with limited or no modifications to support on-orbit operations, the ISS Program worked with commercial industry to develop a power inverter which converts the DC power generated from the ISS solar arrays to AC power just as you would find in your home. Ø The provision of AC power allows ISS systems and payload developers to simplify and reduce the schedule and cost for the development, integration and delivery hardware into the ISS. Ø The ISS power inverter (pictured below) comes in two models: 120Vdc- to120Vac and 28Vdc-to-120Vac respectively to support the primary power input voltages provided throughout the ISS (USOS and Russian Segments) and payload power interfaces.
