US EVA-37 Spacewalk

On Sep 1, 2016 the day that spelled calamity for SpaceX as its Falcon 9 Upgraded booster, laden with Israel’s Amos-6 communications satellite, suffered a catastrophic failure during fueling at Cape Canaveral Air Force Station in Fla, a pair of astronauts smoothly performed a lengthy EVA outside the ISS.
Expedition 48 space walkers Jeff Williams (EV1) and Kate Rubins (EV2) spent 6 hours and 48 minutes retracting and securing the Trailing Thermal Control Radiator (TTCR) and tending other important tasks.

Designated US EVA-37, it followed on the heels of the highly successful US EVA-36 on August 19, during which Williams and Rubins installed the IDA-2 on the PMA-2.

The following photos demonstrates the US EVA-37 spacewalk using my ISS papermodel and astronauts.

The main task has been completed. Now on to replacement light for Camera Group 9 and adding a High Definition Camera.

imageA burned out bulb was removed and a replacement light was installed on the Camera Group 9 on the P1 truss, and the External High Definition Camera Assembly (EHDCA) has been added.

As Williams worked on the CG9 light, Rubins returned to the SARJ (Solar Alpha Rotary Joint) location to perform a visual inspection of the area.

The US EVA-37 has been successfully completed.
