Tak, wydaje się. I tyle w temacie.

Dziwne, że jakość nie jest wyśmienita.
Dlaczego dziwne? Założenia eksperymentu są takie, że przeprowadzany on jest przy użyciu produktów dostępnych cenowo w przeciętnym sklepie. Pudełko to osłona przed promieniowaniem.
Cytat:Research Overview
The High Definition Earth Viewing (HDEV) investigation places four different commercial high definition cameras external to the International Space Station (ISS) on the Columbus External Facility.
These cameras video will assess camera quality for space use while taking Earth imagery.
These cameras assess the hardware's ability to survive and function in the extreme radioactive environment of Low Earth Orbit (LEO).
Educational outreach has been an important component of the HDEV project through the entire projects life cycle. NASA HUNCH program students fabricated some of the HDEV flight components, and most of the HDEV operation will be performed by students teams.

Cytat:The HDEV visible HD video cameras are a fixed payload camera system that requires no zoom, no pan or tilt mechanisms. The four fixed cameras are positioned to capture imagery of the Earth’s surface and its limb as seen from the ISS (i.e., one camera forward pointed into the station’s velocity vector, two cameras aft (wake), and the other one camera pointing nadir). The video imagery is encoded into an Ethernet compatible format for transmission to the ground and further distribution. In this format, the video can be viewed from any computer connected to the internet.
The HDEV does not record video on board the ISS, all video is transmitted to the ground real time; any desired recording of the video occurs as ground operations. The COTS cameras, COTS encoder and other electronics are enclosed in a pressurized box to provide a level of protection to the electronics from the space environment. The Enclosure contains dry nitrogen at Atmospheric pressure.
