On January 2, 2004 NASA’s Stardust spacecraft made a close flyby of comet Wild 2 (pronounced “Vilt-2”). Among the equipment the spacecraft carried on board was a navigation camera. This is the 34th of the 72 images taken by Stardust’s navigation camera during close encounter. The exposure time was 10 milliseconds. The two frames are actually of 1 single exposure. The frame on the left depicts the comet as the human eye would see it. The frame on the right depicts the same image but “stretched” so that the faint jets emanating from Wild 2 can be plainly seen. Comet Wild 2 is about five kilometers (3.1 miles) in diameter. http://photojournal.jpl.nasa.gov/catalog/PIA05571
This mosaic of images from the navigation camera on the European Space Agency Rosetta spacecraft shows the nucleus of comet 67P/Churyumov-Gerasimenko as it appeared at 5 a.m. UTC on Dec. 17, 2014 9 p.m. PST on Dec. 16.
This image shows the most recent observations of the 2-mile-wide 4-kilometer-wide comet 67P/Churyumov-Gerasimenko, which is the upcoming target of the European Space Agency Rosetta mission.
From the location where it came to rest after bounces, the Philae lander of the European Space Agency Rosetta mission captured this view of a cliff on the nucleus of comet 67P/Churyumov-Gerasimenko. The feature is called Perihelion Cliff.
This graphic depicts the position of the Philae lander of the European Space Agency Rosetta mission, and a nearby cliff photographed by the lander, in the context of topographic modeling of the surface of comet 67P/Churyumov-Gerasimenko nucleus.
This mosaic of images from the navigation camera on the ESA Rosetta spacecraft shows the nucleus of comet 67P/Churyumov-Gerasimenko as it appeared at in the early morning, Universal Coordinated Time, of Dec. 17, 2014 evening of Dec. 16, PST.
The Philae lander of Europe Rosetta mission has returned the first panoramic image from the surface of a comet. The unprocessed panorama from the lander CIVA-P camera shows a 360-degree view around the point of final touchdown.
Images of comet 67P/Churyumov-Gerasimenko taken on July 14, 2014, by the OSIRIS imaging system aboard ESA Rosetta spacecraft have allowed scientists to create this three-dimensional shape model of the nucleus.
This composite image was taken by the navigation camera during the close approach phase of Stardust’s Jan 2, 2004 flyby of comet Wild 2. Several large depressed regions can be seen. Comet Wild 2 is about five kilometers (3.1 miles) in diameter. To create this image, a short exposure image showing tremendous surface detail was overlain on a long exposure image taken just 10 seconds later showing jets. Together, the images show an intensely active surface, jetting dust and gas streams into space and leaving a trail millions of kilometers long. http://photojournal.jpl.nasa.gov/catalog/PIA05578
This image was taken by the Optical, Spectroscopic, and Infrared Remote Imaging System, Rosetta main onboard scientific imaging system, on Sept. 10, 2014. Jets of cometary activity can be seen along almost the entire body of the comet. http://photojournal.jpl.nasa.gov/catalog/PIA18886
