High Definition Earth Viewing (HDEV) cameras were a payload package delivered to the International Space Station on the SpaceX CRS-3 Mission, launched on April 18, 2014. The High-Definition Earth Viewing camera suite was carried aboard the Dragon spacecraft and is configured on a platform on the exterior of the European Space Agency's Columbus laboratory module. It was the first large unpressurized NASA experiment to be assigned for delivery to the International Space Station by SpaceX. The system is composed of four commercial high definition video cameras which were built to record video of the Earth from multiple angles by having them mounted on the International Space Station. The cameras streamed live video of Earth to be viewed online and on NASA TV on the show Earth Views. Previousl
