Fans of science in space now can experience fast-moving footage in even higher definition as NASA and ESA (European Space Agency) deliver the first 8K ultra high definition (UHD) video of astronauts living, working and conducting research from the International Space Station. The same engineers who sent high-definition (HD) cameras, 3D cameras, and a camera capable of recording 4K footage to the space station now have delivered a new camera capable of recording images with four times the resolution than previously offered.
The Helium 8K camera by RED, a digital cinema company, is capable of shooting at resolutions ranging from conventional HDTV up to 8K, specifically 8192 x 4320 pixels. By comparison, the average HD consumer television displays up to 1920 x 1080 pixels of resolution, and digital cinemas typically project in resolutions of 2K to 4K.
“This new footage showcases the story of human spaceflight in more vivid detail than ever before,” said Dylan Mathis, communications manager for the International Space Station Program at NASA’s Johnson Space Center in Houston. “The world of camera technology continues to progress, and seeing our planet in high fidelity is always welcome. We're excited to see what imagery comes down in the future.”
