The ISS Flight Science & Image Analysis Group perform activities such as identifying hypervelocity impacts, damaged solar arrays, discolorations, and other damage on the ISS external surfaces related to the space environment. Acquire and analyze imagery of the ISS in support of assembly, operations, vehicle configuration and performance, anomaly investigations, and to detect and monitor changes affecting the long-term health of the station. The Image Science and Analysis Laboratory (ISAL) provides expertise in scientific and engineering analysis of image assets, including still imagery and video. Specialty areas include photogrammetry, high-precision motion tracking, imagery enhancement and restoration, data visualization, imagery-based inspection and surveys, imagery acquisition planning, and imagery operations management.
The paper will discuss the ISS Flight Science & Image Analysis Group periodic inspections of the exterior of ISS. Surveys are performed periodically using the ISS External Television Camera Group (ETVCG) cameras and the newly installed EHDC ETVCGs.
Survey Objectives:
- Detect, assess, and monitor exterior ISS degradation
- Identify visible anomalies, including MMOD strikes, discolorations and out of configurations per drawings.
- Verify and document the ISS hardware configuration
- Perform surface assessments and analysis of the ISS external surfaces and components via high-resolution survey photography.
- Acquire imagery of the lifted face sheet on the starboard Heat Rejection System (HRS) Radiator and provide periodic monitoring. "https://isal-web1.jsc.nasa.gov/content/folder341/Inboard_radiator_damage.htm"
- Inspect and monitor the lifted panel on the SM Module and provide periodic monitoring. "https://isal-web1.jsc.nasa.gov/content/folder793/SM_structual_Panels_lifting.htm"
- Acquire imagery of the repaired P6 Solar Array Wing (SAW) and provide periodic monitoring. "https://isal-web1.jsc.nasa.gov/content/folder1578/Inc41_P6-1.htm"
- Provide analysis on the CKK Experiment Panels (on Service Module) and provide periodic monitoring. "https://isal-web1.jsc.nasa.gov/content/folder1244/CKK.htm"
Detailed Test Objectives (DTOs) and Imagery provided in the downlink by the Crew are also used for analysis.
The intent of this paper is to bring a greater awareness of the harsh space conditions the ISS operates and functions in daily. Also, having the situational awareness of the space weather environment.
