The High Definition Earth Viewing (HDEV) experiment places four commercially available HD cameras on the exterior of the space station and uses them to stream live video of Earth for viewing online. The High Definition Earth Viewing (HDEV) experiment aboard the ISS was activated April 30, 2014. 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. High school students helped design some of the cameras’ components, through the High Schools United with NASA to Create Hardware (HUNCH) program, and student teams operate the experiment.
