The official match ball for the 2026 FIFA World Cup, the Adidas Trionda, has made an unusual pre-tournament journey: outer space. Astronauts aboard the International Space Station (ISS) studied the ball in microgravity as part of a NASA experiment examining ball movement, balance, and performance, according to the US space agency.
NASA and ISS Crew Recreate 2019 Study
NASA shared images of the exercise, stating that the ISS crew recreated a 2019 study using the official World Cup ball to understand how a football's balance and centre of mass influence its movement. “The official FIFA World Cup ball went to space,” NASA said in an Instagram post. Sports engineers carefully measure and optimise a football's centre of mass and balance to ensure predictable movement during matches. The ISS crew repeated the experiment to demonstrate the effects of both good and poor balance on a football's flight characteristics.
Impact on On-Field Performance
NASA said the research has helped scientists better understand how embedded technologies, including match-ball sensors, can affect on-field performance. “Helping to improve the beautiful game is just one of the ways NASA science done on the International Space Station makes life better for people on Earth,” the agency stated.
Trionda: Design and Technology
Developed by Adidas, the Trionda will be used during the 2026 FIFA World Cup, jointly hosted by Canada, Mexico, and the United States. According to FIFA, the name Trionda is derived from a Spanish phrase meaning “three waves,” symbolising the three host nations. The ball features red, green, and blue design elements representing the three countries. Its four-panel construction forms a triangular shape at the centre, with symbols such as a maple leaf, an eagle, and a star paying tribute to Canada, Mexico, and the US, respectively.
FIFA says the ball incorporates several performance-focused innovations, including deeper seams designed to improve flight stability and embossed surface details aimed at enhancing grip in wet conditions. The Trionda is also equipped with connected-ball technology featuring a 500Hz motion sensor chip that transmits real-time movement data to the Video Assistant Referee (VAR) system, assisting officials in decisions on offsides and other key match incidents.
Intersection of Football and Space Science
The experiment marks a rare intersection of football and space science, with the official World Cup ball becoming the latest piece of sporting equipment tested aboard the ISS.
