The video description says:
Published on Apr 15, 2015 This footage was taken by U.S. astronaut Terry Virts during a spacewalk on the International Space Station on February 25, 2015. Virts and fellow astronaut Barry “Butch” Wilmore routed a series of cables in preparation for the arrival of two International Docking Adapters later in 2015. Virts also lubricated elements at the latching end of the space station’s Canadarm2 robotic arm while Wilmore prepares the Tranquility module for the relocation of the Permanent Multipurpose Module and the arrival of the Bigelow Expandable Activity Module (BEAM) later this year.
Can anyone identify the source of the sounds recorded by the GoPro?
This answer describes another GoPro video, and why the recorded sounds transmitted through air became more audible as the air density increased, around 30km altitude. But the current video is from the ISS at 400km. I'm guessing the sounds is transmitted mechanically from something in contact with the camera. Is it related to the astronaut's EVA suit, or the ISS?
Thanks to @BrianTompsett for linking to this GoPro video.
