Helene of Troy

Helene Attends Dione

NASA Cassini spacecraft imaged the surface of Saturn moon Helene as the it flew by the moon on Jan. 31, 2011. Helene is a Trojan moon of Dione, named for the Trojan asteroids that orbit 60 degrees ahead of and behind Jupiter as it circles the Sun.

NASA Cassini spacecraft snapped this image during the spacecraft closest flyby of Saturn moon Helene, on March 3, 2010. Helene is a Trojan moon of Dione, named for the Trojan asteroids that orbit ahead of and behind Jupiter.

Cassini came close to Saturn small moon Helene on Feb. 25, 2006, acquiring this high-resolution view. This object seems to be buried in its own crater debris, like another Saturnian moon, Telesto

Saturn small, irregularly shaped moon Helene is strikingly illuminated in this close view captured by NASA Cassini during the spacecraft June 18, 2011, flyby.

Although travelling at great speed, NASA Cassini spacecraft managed to capture this close view of Saturn small moon Helene during a flyby on March 3, 2010.

NASA Cassini spacecraft snapped this image of Saturn moon Helene while completing the mission second-closest encounter of the moon on June 18, 2011.

This set of images exposes details on small and crumpled-looking Helene. Large portions of this Trojan moon of Dione appear to have been blasted away by impacts

This anaglyph, from NASA Shuttle Radar Topography Mission, is of Mount St Helens, Washington. 3D glasses are necessary to view this image.

On May 18, 1980, Mount St. Helens catastrophically erupted, causing the worst volcanic disaster in the recorded history of the United States.

This NASA Terra satellite image of Mount St. Helens was captured one week after the March 8, 2005 ash and steam eruption, the latest activity since the volcano reawakening in September 2004.

This 3-D anaglyph image of Mt. St. Helens volcano combines the nadir-looking and back-looking band 3 images of ASTER. To view the image in stereo, you will need blue-red glasses. Make sure to look through the red lens with your left eye. This ASTER image of Mt. St. Helens volcano in Washington was acquired on August 8, 2000 and covers an area of 37 by 51 km. Mount Saint Helens, a volcano in the Cascade Range of southwestern Washington that had been dormant since 1857, began to show signs of renewed activity in early 1980. On 18 May 1980, it erupted with such violence that the top of the mountain was blown off, spewing a cloud of ash and gases that rose to an altitude of 19 kilometers. The blast killed about 60 people and destroyed all life in an area of some 180 square kilometers (some 70 square miles), while a much larger area was covered with ash and debris. It continues to spit forth ash and steam intermittently. As a result of the eruption, the mountain's elevation decreased from 2,950 meters to 2,549 meters. The image is centered at 46.2 degrees north latitude, 122.2 degrees west longitude. http://photojournal.jpl.nasa.gov/catalog/PIA11160

Mount Saint Helens is a prime example of how Earth topographic form can greatly change even within our lifetimes.

Mount St. Helens, Washington, erupted 40 years ago, on May 18, 1980. A massive debris avalanche, triggered by an earthquake of magnitude 5.1, caused a lateral eruption that reduced the elevation of the mountain's summit from 2,950 m to 2,549 m, leaving a 1.6 km wide horseshoe-shaped crater. The collapse of the northern flank resulted in massive volcanic mudflows. Since 1980, new lava built a dome in the crater, and occasional steam and ash plumes have been emitted. The Landsat MSS image was acquired July 31, 1980, and the ASTER image (Figure 1) on July 28, 2019. The images cover an area of 30 by 30 km, and are located at 46.2 degrees north, 122.2 degrees west. https://photojournal.jpl.nasa.gov/catalog/PIA23913

This frame from an animation depicts the growth of the lava dome at Mount St. Helens during the most recent period of activity. Lidar data courtesy USGS.

NASA's Observational Products for End-Users from Remote Sensing Analysis (OPERA) project generated a radar image of Hurricane Helene on Friday, Sept. 26, 2024, at 7:38 p.m. local time, as the storm approached the Florida coast. One of the largest storms to develop in the Gulf of Mexico in the last century, Helene made landfall as a Category 4 hurricane in the Big Bend area of Florida at about 11:10 p.m. The data shown in the image is from the synthetic aperture radar (SAR) instrument on the Copernicus Sentinel-1A satellite, operated by the European Space Agency (ESA), and processed by OPERA into a data product called OPERA RTC-S1. The OPERA RTC-S1 image was converted to a false color image. In this color scale, vegetated areas appear green, urban areas appear white/pink, calm water appears black, and rough water appears purple or magenta. The eye of the hurricane can be clearly seen as a large dark patch in the Gulf of Mexico. The OPERA RTC-S1 image was superimposed on a Google Earth satellite background shown in grayscale and the ESRI Boundaries Places layer. https://photojournal.jpl.nasa.gov/catalog/PIA26414

NASA's Atmospheric Infrared Sounder (AIRS) captured an infrared image of Hurricane Helene on Friday, Sept. 27, 2024, at 3:47 a.m. local time, nearly five hours after it made landfall on the Florida coast. One of the largest storms to develop in the Gulf of Mexico in the last century, Helene made landfall as a Category 4 hurricane in the Big Bend area on Sept. 26, at about 11:10 p.m. In the infrared images, the large purple areas indicate very cold clouds carried high into the atmosphere by deep thunderstorms and associated with heavy rainfall. Warmer areas with shallower rain clouds are shown in blue and green. The orange and red areas represent mostly cloud-free air. The eye of the hurricane can be seen as a small blue dot in the middle of the large purple patch. AIRS, in conjunction with the Advanced Microwave Sounding Unit (AMSU), senses emitted infrared and microwave radiation from Earth to provide a 3D look at Earth's weather and climate. Working in tandem, the two instruments make simultaneous observations down to Earth's surface. With more than 2,000 channels sensing different regions of the atmosphere, the system creates a global, 3D map of atmospheric temperature and humidity, cloud amounts and heights, greenhouse gas concentrations and many other atmospheric phenomena. Launched into Earth orbit in 2002, the AIRS and AMSU instruments fly onboard NASA's Aqua spacecraft and are managed by NASA's Jet Propulsion Laboratory in Southern California under contract to NASA. JPL is a division of the Caltech. https://photojournal.jpl.nasa.gov/catalog/PIA26413
