Wind Sled, Spanish invention to cross Antarctica with out emissions: ‘Distinctive within the global community’
Spanish polar explorer Ramón Larramendi is about to steer a scientific expedition that can journey round 3,400 kilometres throughout the inside of Antarctica over roughly 80 days, with out utilizing fossil fuels for transport. The Wind Sled Antarctica 2026-2027 challenge will carry devices to conduct 16 research projects (source in Spanish) in a number of the most inaccessible areas on the planet, with the intention of increasing information about ice, local weather change and polar ecosystems.

“The wind sled is, in a method, fully distinctive within the global community,” Larramendi tells ‘Euronews’ in an interview in Madrid’s central Plaza de España. The explorer believes that the car he has designed is an distinctive mixture of conventional strategies and superior expertise, conceived to cowl lengthy distances with out combustion engines or aerial resupply.
The expedition will go away Spain on 18 October and is scheduled to return in early February. The route will begin close to Russia’s Novolazarevskaya base, in Queen Maud Land, and finish on the French-Italian Concordia station on Dome C, after crossing the Pole of Inaccessibility and skirting the neighborhood of the Pole of Cold.
A wind-powered car to cross Antarctica with zero emissions
The Wind Sled is a polar exploration platform that makes use of kites to harness the facility of the wind and photo voltaic power to energy scientific gear. Its design, impressed by Inuit culture, as Larramendi explains, is the results of round 25 years of growth and testing, throughout which he has travelled greater than 28,000 kilometres over ice on completely different expeditions.
“This sled combines Inuit strategies, which can look old style and a bit unusual in contrast with trendy expertise. That makes it a really, very uncommon combine, however tremendously environment friendly,” says the explorer, who sees sustainability as one of many basic pillars of the challenge.
The car is made up of 4 modules and is 15 metres lengthy. It can carry as much as 2,100 kilos of cargo, though on this event it should initially transport round 250 kilos of scientific devices.
The crew may have 20 kites, with floor areas starting from 5 to 150 sq. metres, which they’ll deploy in line with the climate circumstances. In beneficial winds, the sled can attain speeds of as much as 80 kilometres per hour, with a mean cruising pace of round 25 kilometres per hour.
The absence of fossil fuels reduces each the environmental affect and the logistical wants of the expedition. As a degree of comparability, the Transantarctic Scientific Expedition of 2011-2012 lined the same distance utilizing tracked vans, snowmobiles and sleds, consuming round 170,000 litres of gas in two months.
Larramendi hopes this marketing campaign will reveal the car’s potential as a scientific platform for future crossings. “Other methods powered by renewable power could emerge to cross Antarctica, however none can be extra sustainable or have a smaller footprint than the Wind Sled,” he argues.
Sixteen tasks to review ice, pollution and microbial life
The expedition will perform 16 scientific tasks chosen by way of a name coordinated by the Spanish Polar Committee. The analysis, involving centres from CSIC, CIEMAT, INTA, six Spanish universities and transnational organisations, will present direct measurements in areas the place hardly any knowledge exist, complementing data gathered by satellites and everlasting stations.
Among the research is a challenge from NASA’s Ames Research Center, led by Spaniard Alfonso Dávila, which can study whether or not circumstances beneficial to microbial life can come up inside salt rocks uncovered to Antarctica’s excessive chilly. Sensors will measure temperature, relative humidity and electrical conductivity to find out whether or not liquid water might have shaped inside them regardless of the low temperatures and the arid setting.
Another challenge, referred to as Dinglac and led by glaciologist Francisco Navarro of the Polytechnic University of Madrid, will use ground-penetrating radar to analyse the primary ten metres of snow. The measurements will assist to grasp how snow layers accumulate and transfer and to enhance estimates of how the Antarctic ice mass is evolving within the context of local weather change.
The marketing campaign can even examine the presence of microplastics, persistent pollution and attainable microorganisms and viruses, in addition to finding out Earth’s magnetism and the efficiency of Europe’s Galileo navigation systems. Some of the experiments will use gear linked to house exploration.
For Larramendi, the worth of this work additionally lies in the truth that it should happen in territory that’s just about unknown from a scientific perspective. “It takes place in an space for which there are virtually no knowledge,” he explains. The system makes it attainable to enterprise into areas the place the difficulties and prices of typical operations imply analysis campaigns are notably advanced.
Four folks remoted for 85 days: an experiment for future house missions
The expedition group will consist of 4 Antarctic veterans: Larramendi himself; Hilo Moreno, polar information and mountain technician; Mariusz Potocki, a researcher on the University of Maine within the United States; and Javier Selva, photographer, documentary maker and head of technical picture path. Selva already accompanied Larramendi on an Antarctic expedition between 2011 and 2012.
In addition to participating within the fieldwork, the 4 explorers will themselves be the topic of research. The WindSled Mind challenge, led by Gabriel G. de la Torre from the University of Cádiz, will analyse the results of extended isolation on the crew’s psychological responses, sleep and social dynamics. “We are a part of the analysis challenge and sure, we do really feel a bit like guinea pigs, however we’re blissful,” Larramendi jokes.
The analysis goals to generate information relevant to future long-duration house missions, by which astronauts must face circumstances of confinement, hazard and excessive distance from Earth. Antarctica is without doubt one of the best suited environments on the planet for finding out these components and testing devices destined for future planetary exploration.
“We ourselves are the experiment. Four folks remoted for 85 days within the inside of the Antarctic continent,” Larramendi acknowledges. The explorer explains that there are two tasks by which the members of the expedition themselves are the topic of analysis.
Self-sufficiency can be one of many keys to the journey. The group will carry all of the provides and gear wanted to stay for weeks with out outdoors assist, though they have an evacuation plan in place in case of a medical emergency or another distinctive scenario.
A pioneering route with an eye fixed on future expeditions
The journey, which will be adopted stay on the web site tierraspolares.es (source in Spanish), is the fruits of a long time of labor on the Wind Sled and can take a look at its capability to hold an unprecedented scientific payload on Larramendi’s Antarctic expeditions. The 4 group members will arrange 5 scientific stations alongside the route, with prolonged stops to gather samples, run experiments and take measurements.
On arrival at Concordia, the explorers will go away the continent by air, whereas the scientific gear will return to Spain with French assist. The sled will stay dismantled on the base, prepared for a attainable future journey in the other way.
The intention is to repeat the expeditions in order that the info gathered on completely different campaigns will be in contrast, one thing important for figuring out modifications within the ice and the local weather. “Repeated knowledge assortment is completely key to seeing the variations,” Larramendi factors out.
The journey, integrated (source in Spanish) into the fortieth Antarctic Research Campaign, which marks the fortieth anniversary of Spain’s polar expedition, goals to consolidate a low-impact scientific exploration route within the inside of the continent. It affords another that mixes analysis in considered one of Earth’s most excessive areas with the event of applied sciences that might contribute to future house missions.
