Quick Look: The Spaceporium channel on Roku appears to source its videos from Space.com and the Space.com YouTube channel. The channel contains well over 100 on-demand videos, with a much larger library available on their YouTube channel. The videos range in content from vintage films showing launches from the 1960s and videos of Earth from space to more recent endeavors and interviews with astronauts. Unfortunately the content is not organized and each video is preceded by a short commercial.
Below is an video found on the Space.com YouTube channel.
