As NASA says, "The cameras are enclosed in a temperature specific housing and are exposed to the harsh radiation of space."
"Analysis of the effect of space on the video quality, over the time HDEV is operational, may help engineers decide which cameras are the best types to use on future missions."
It's fascinating to watch and is strangely relaxing. Enjoy!
