The impact of the European Space Agency (ESA) SMART-1 Lunar Orbiter onto the Lunar surface was captured by the ground-based Canada-France-Hawaii Telescope (CFHT), a 3.6-meter optical/infrared telescope located atop Mauna Kea in Hawaii. The the impact flash was captured by an infrared camera and was possibly caused by the release of a small amount of hydrazine fuel remaining on board.
