![]() ![]() Normally, summer rains fill Poyang Lake in central Jiangxi province, and a drier winter shrinks it. NASA will continue to work with USGS to strengthen and improve accessibility to Landsat data so decision makers in America – and around the world – better understand the devastation of the climate crisis, manage agricultural practices, preserve precious resources and respond more effectively to natural disasters. An extended heat wave and drought have caused China’s largest freshwater lake to reach low-water levels not seen in decades. “This program has the proven power to not only improve lives but also save lives. Geological Survey that provides critical data about Earth’s landscapes and coastlines seen from space,” NASA administrator Bill Nelson said in a statement. “Landsat 9’s first images capture critical observations about our changing planet and will advance this joint mission of NASA and the U.S. of distance is mainly of advantage to those. Two major components of the NISAR satellite have been combined to create a single spacecraft in Bengaluru, India. When the image is reorded as digital data, the matching ocedures ( registration ) can be sed to detect changes in ground atures as a function of time. The satellite’s other instrument, Thermal Infrared Sensor 2 (TIRS-2), observes thermal radiation in two wavelengths to measure Earth’s surface temperatures and its changes, and can help experts track plant health. In Brief: Built on opposite sides of the planet, the NISAR satellite will deepen understanding of climate change, deforestation, glacier melt, volcanoes, earthquakes, and more. In celebration of this year’s Earth Day on April 22, NASA’s Webby Award-winning Global Climate Change website,, has unveiled a new version of its popular image gallery, State of Flux. NASA and Boeing have teamed up to build an experimental passenger plane to help achieve the U.S. Riggs Glacier has retreated some 0.4 miles (0. In the 2004 photograph, Muir Glacier, continuing a retreat nearly two centuries long, is located about 4 miles (7 kilometers) to the northwest, out of the field of view. The next front in Facebook's misinformation battle: climate change The 1941 photograph shows the lower reaches of Muir Glacier and its tributary, Riggs Glacier. The wildfire west of Lake Isabella in Kern County has burned over 20,000 acres while threatening homes in and around Wofford Heights and Kernville. Visit our resources page for more information and activities related to the DART mission.Kern County Fire Captain Bruce Wells uses a hose line to keep fire from burning up a tree as the wildfire burns closer to homes during the French Fire in the Sequoia National Forest near Wofford Heights, California on August 25, 2021. This series of satellite images shows the ozone hole on the day of its maximum depth each year from 1979 through 2019. Below you will find a gallery that will continue to be updated as new images are taken of the Didymos asteroid system.ĭART’s target asteroid is not a threat to Earth but is the perfect testing ground to see if this method of asteroid deflection – known as the kinetic impactor technique – would be a viable way to protect our planet if an asteroid on a collision course with Earth were discovered in the future. In the early 1980s, scientists began to realize that CFCs were creating a thin spota holein the ozone layer over Antarctica every spring. Over the coming weeks, ground based observatories around the world will characterize the ejecta produced by DART’s impact and precisely measure Dimorphos’ orbital change to determine how effectively DART deflected the asteroid. Right of this line, the ice shelf rests on bedrock. The dark blue line that appears in both images illustrates where the edge of the land lies, beneath the ice. The 2018 image was taken following a period of drought that began in 2000. as the world's first attempt to move an asteroid in space. These images show 33 years of changes in Antarctica’s Brunt Ice Shelf. The 1984 image shows Lake Powell a year after its highest water level was recorded. After 10 months flying in space, NASA’s Double Asteroid Redirection Test (DART) – the world’s first planetary defense technology demonstration – successfully impacted its asteroid target on Monday, September 26 at 7:14 p.m.
