But compared to a century ago, the difference is gigantic.”. pertaining to frame ephemeris data, orbital ephemeris data, and mission “It hasn’t been used that much yet. With an archive of almost one million images, the program detected Soviet missile sites, warships, naval bases and other military targets. To do that, thousands of people have been working around... The same site in Armenia, showing loss of forested areas. with the issuance of this Executive Order. In the last two years alone, scientists have studied the images to track rock glacier movements in Central Asia, shoreline changes in Saudi Arabia, wadi trees in eastern Egyptian deserts and ice loss in Peru. the systems code-named CORONA, ARGON, and LANYARD. A diagram showing how the camera systems on the Corona satellites worked. A Corona program satellite being recovered in mid-air, from the film, “A Point in Time: The Corona Story,” co-produced by the Central Intelligence Agency and the National Reconnaissance Office.Credit... Not being able to see the forest for the trees isn’t just a colloquialism for Mihai Nita — it’s a professional disadvantage. It became the first photography ever recovered from orbit. Compared to today’s digital cameras and satellites that store or transmit information to us immediately, the Corona used actual film that had to be ejected from the satellite and recovered before it could be viewed. “In a lot of cases, they lead us to landscapes that are gone, that don’t exist anymore” Dr. Ur said. not produced for unsuccessful missions. In the process, these orbiting observers gathered approximately 850,000 images that were kept classified until the mid-1990s. To map a landscape’s history, foresters like Dr. Nita long depended on maps and traditional tree inventories that could be riddled with inaccuracies. With this and other technical advances, research using Corona data has picked up. In 2019, for example, a group of scientists used Corona images, historical maps and modern satellites to retrace the fluctuating boundaries of Nepal’s Phewa Lake over time. 1995-01-01. But now they have a bird’s-eye view that is the product of a 20th century American spy program: the Corona project, which launched classified satellites in the 1960s and ’70s to peer down at the secrets of the Soviet military. The images “We needed an eye in the sky.”. By examining black-and-white Corona images and marking the forest’s outline by hand, Dr. Leempoel demonstrated in 2013 that human activity had driven mangrove cover down by more than a third from 1967 to 2009. read more, https://project-open-data.cio.gov/v1.1/schema/catalog.jsonld, https://project-open-data.cio.gov/v1.1/schema, https://project-open-data.cio.gov/v1.1/schema/catalog.json. One reason for their relative obscurity is that scientists who wanted to use the images have needed to overcome a variety of obstacles. A satellite image from the 1960s of the future site of a dam in Turkey. “It can go a long way in telling you what equipment they have and what their state of readiness is.”. images, documents and reports (collateral information) are available, U-2 spy plane photos (left, October 1959) offer imagery at a much higher resolution than CORONA spy satellite images (right, May 1968). With Corona imagery, archaeologists can go “somewhen” and peer at the world as it had looked half a century ago. “In ecology, we’re all faced with the same issue: We start to have good data in the ’80s or ’90s at best,” Dr. Leempoel said. “The difference between today and then is not huge. This, paradoxically, helps us predict what comes next. “It’s Google Earth in black and white,” said Catalina Munteanu, a biogeographer at Humboldt University of Berlin who has used Corona images to show that marmots returned to the same burrows throughout decades of destructive agricultural practices in Kazakhstan. “We can use imagery in the past to inform the future,” said C. Scott Watson, a geoscientist at the University of Leeds and co-author of the Phewa Lake study. On February 24, 1995, President Clinton signed an Executive Order, Imagery from the Cold War’s Corona satellites is helping scientists fill in how we have changed our planet in the past half century. The age of satellite reconnaissance had begun.The initial Corona payload involved a single panoramic camera with a resolution of 35-40 feet. Center for Advanced Spatial Technologies. What’s new. Document availability varies by mission; documentation was Illinois Historical Aerial Photographs are available free-of-charge via. General Use. https://cmr.earthdata.nasa.gov:443/search/concepts/C1220566178-USGS_LTA.html, 1960-07-31T00:00:00Z/1972-05-31T23:59:59Z. Dr. Nita’s research interest — the history of Eastern Europe’s forests — depends on a vaster, and more removed, vantage than eyes can provide. Satellite reconnaissance offered a glimpse into the Soviet black box, said James David, a curator at the Smithsonian National Air and Space Museum in Washington. “You have to see what happened in the ’50s, or even a century ago,” Dr. Nita said. CORONA satellite imagery, preserving an account of the earth's surface from 40 years ago, is a most important archaeological survey tool and we have often sung its praises. Then, the researchers predicted what could come next, estimating that the shrinking lake could lose 80 percent of its water within the next 110 years. A Corona program image of Boslebi village in Georgia, during a period of collective farming under the Soviet Union. developments in then-Soviet strategic missile capabilities. Often, Corona’s ’60s-era snapshots captured habitats before humans dramatically inundated, paved over, plowed up or developed wild spaces into new cities, hydroelectric dams, farmland or industrial zones. Paired with modern computing, the space-based snapshots have helped archaeologists identify ancient sites, demonstrated how craters left by American bombs during the Vietnam War became fish ponds and recounted World War II’s reshaping of Eastern Europe’s tree cover. an interactive map (102 counties) for data viewing or download of all file formats; a list of counties (102 counties) for data viewing or download of all file formats; If you have any trouble with the interactive map please contact Dee Lund.Instructions for the map will be added soon. Sioux Falls, South Dakota, SILVIS Lab/University of Wisconsin-Madison. In Mapping Archaeological Landscapes from Space, edited by Comer, Douglas C. and Harrower, Michael J., pp. directing the declassification of intelligence imagery acquired by the Using declassified images from a government satellite program called CORONA, the researchers are working with high-resolution digital scans distributed by … FUN FACT When the Corona satellite camera was first used, it only had a resolution of about 40 feet. ArcGIS Living Atlas of the World is the foremost collection of geographic information from around the globe. 33 – 43. More than 860,000 images When the camera had used all 20 pounds of its film, the satellite released its film return capsule from a 100-mile altitude. It Spied on Soviet Atomic Bombs. also were used to produce maps and charts for the Department of Defense Scientists unpacked the Corona camera capsule, from footage in “A Point in Time: The Corona Story.”. The Corona Digital Atlas of the Middle East Project hosts a large number … With climate change and other global ecosystem transformations, it’s never been more important to record and piece together long-term environmental timelines, Dr. Munteanu said: “Everything we do leaves a footprint. U.S. Geological Survey. MODIS data at 250-m resolution serve as a base for several national and regional maps in this atlas and for assessing vegetation condition. Explore recent images of storms, wildfires, property and more. Download Corona Imagery. Image collection was driven, in part, by the need to confirm purported Satellite images show the hospitals being built to deal with the deadly coronavirus outbreak in the Chinese city of Wuhan. The images even challenged our assumptions about untouched ecosystems — revealing, more than once, that presumed old-growth forests are actually younger than 70 years old. Springer, New York. In 2013, Kevin Leempoel, a biologist, set out to retrace the historical boundaries of mangroves in Zhanjiang Mangrove National Nature Reserve in China’s south. Since then, the program has remained relatively unknown to the public. performance. first generation of United States photo-reconnaissance satellites, including Image collection was driven, in part, by the need to confirm purported developments in then-Soviet strategic missile capabilities. USA. Even though they’re static, the panoramic photos contain discernible imprints — penguin colonies in Antarctica, termite mounds in Africa and cattle grazing trails in Central Asia — that reveal the dynamic lives of earthly inhabitants below. Download GeoTIFF (xxx MB) Advanced Use. CORONA Atlas Project. Four views of the earliest satellite camera of the Corona program. A loss of that magnitude would devastate the lake’s ability to supply water for hydroelectricity generation, irrigation and tourism activities that hundreds of thousands of people in Nepal rely on, they noted. “They had no idea if these systems would work,” said Compton Tucker, a senior earth scientist at NASA’s Goddard Space Flight Center.
