Spanish Kite‑Powered Sled Tries Zero‑Fuel Antarctic Trek

A Spanish team is attempting a 3,400‑km Antarctic interior crossing without any fuel, using a kite‑powered sled called the Wind Sled. The expedition, led by polar explorer Ramón Larramendi, will travel from Russia’s Novolazarevskaya base to the Concordia station at Dome C, covering 2,100 miles over 85 days. The 15‑meter sled, built on Inuit sled‑building techniques, carries 250 kilograms of instruments and is propelled by up to 20 kites that can reach 80 km/h in strong winds. Sixteen research projects will run on the route, including NASA studies of salt rock microbial life, ground‑penetrating radar mapping of snow layers, and microplastic sampling. The crew of four, all Antarctic veterans, will also serve as subjects for the WindSled Mind project, which will monitor psychological and physiological responses to 85 days of isolation. Data gathered each season will enable scientists to track changes in ice, climate, and polar ecosystems, offering a repeatable method for long‑term observation. By eliminating the 45,000‑gallon fuel consumption of previous crossings, the Wind Sled aims to demonstrate a sustainable, low‑impact approach to polar exploration.
