![]() ![]() Built by the Italian Space Agency, Agenzia Spaziale Italiana, the infrared imager was able to capture 125-mile-wide (202-kilometer-wide) Loki Patera, the largest volcanic depression on Io. “Io is known for its extreme volcanic activity, but after 16 years, it is so nice to see these changes up close again.ĭuring that same May 16 pass, JIRAM found a smoking gun of its own. ![]() “When I compared it to visible-light images taken of the same area during Galileo and New Horizons flybys (in 19), I was excited to see changes at Volund, where the lava flow field had expanded to the west and another volcano just north of Volund had fresh lava flows surrounding it,” said Jason Perry of the University of Arizona’s HiRISE Operations Center in Tucson. Such smudges are smoking guns to planetary scientists. Story by Lindsey Doermann.During Juno’s last flyby of Io, which occurred May 16, the JunoCam imager took a picture from 22,100 miles (35,600 kilometers) showing a smudge at the moon’s Volund region, near the equator. NASA Earth Observatory image by Wanmei Liang, using Landsat data from the U.S. In October, Windpark Fryslân will be the site of the Windmill Cup, a sailing race that courses through the turbines. While the island is only 2 hectares (5 acres) in size, it is surrounded by 25 hectares (60 acres) of shallow water that provides habitat for fish.Īlong with a new power source and wildlife habitat, the Dutch have found new recreational opportunities associated with wind project. ![]() Nearby, an artificial island that was created as a construction platform now serves as a nature reserve and bird sanctuary. One of the two sets of locks in the dike is located at Kornwerderzand. In addition, installing the rotors, which are 130 meters (430 feet) in diameter, required finding windows of relative calm in a naturally windy place. The vessels had to both fit through the locks in the dike and operate in the shallow waters of the lake. A major constraint was the size of ships that could be used to transport construction materials and turbine components to the site. In 2022, the installation produced 1.236 terawatt hours.Ĭonstructing the wind farm in Lake IJssel posed unique challenges, according to the company Van Oord, which was part of the consortium that built Windpark Fryslân. This is equivalent to approximately 1.2 percent of electricity use in the Netherlands, or enough to power about 500,000 households. The wind farm came online in autumn 2021 with the capacity to generate 1.5 terawatt hours annually. The 32-kilometer-long (20-mile-long) Afsluitdijk, which provides flood protection and separates the lake from the Wadden Sea, is also prominent in the image. ![]() Their arrangement in a hexagon shape is intended to minimize how much the installation obstructs the view of the horizon. In this image, acquired by the Operational Land Imager (OLI) on Landsat 8 on July 8, 2023, Windpark Fryslân’s precisely spaced turbines are seen rising out of Lake IJssel. Windpark Fryslân, an array of 89 wind turbines clustered within a hexagon shape, is the largest freshwater wind farm in the world. So it may come as little surprise that the Netherlands is home to a modern, second-to-none wind energy installation. Suffice it to say, the Dutch have a history with wind power. Today’s story is the answer to the July 2023 puzzler. ![]()
