Astronaut Don Pettit Recreates the Stargate Sequence From "2001"
Below is a frame from the "Stargate Sequence" from the iconic film "2001: A Space Odyssey".
These three images below are a composite of a series of images photographed from a mounted camera on the Earth-orbiting International Space Station. Expedition 31 Flight Engineer Don Pettit is the photographer. It would seem that he has managed to recreate the stargate sequence - in space.
Expedition 31 Flight Engineer Don Pettit relayed some information about photographic techniques used to achieve the images: "My star trail images are made by taking a time exposure of about 10 to 15 minutes. However, with modern digital cameras, 30 seconds is about the longest exposure possible, due to electronic detector noise effectively snowing out the image. To achieve the longer exposures I do what many amateur astronomers do. I take multiple 30-second exposures, then 'stack' them using imaging software, thus producing the longer exposure." A total of 46 images photographed by the astronaut-monitored stationary camera in the Cupola were combined to create this composite. Other locations on the orbital outpost were used by the crew to mount cameras to achieve other composites.
