The official match ball of the FIFA World Cup 2026, the Adidas Trionda, has been sent to the International Space Station (ISS) as part of a science demonstration examining how a football's centre of mass and balance behave in microgravity. NASA announced the experiment, describing it as a rare convergence of space research and sports engineering that has direct implications for how match balls perform on the pitch.

The Science Behind the Experiment

The current ISS crew recreated a 2019 experiment — originally conducted in partnership with the ISS National Laboratory — using the new Trionda to compare how differently balanced footballs spin and move when gravity is removed from the equation. According to NASA, the findings from that original study improved understanding of how a ball's internal mass distribution affects its motion, stability, and rotation during play.

Crucially, the research also shed light on how embedded technologies — particularly match-ball sensors — can influence ball performance. NASA said the work contributed to studies used in the development and evaluation of footballs for major international tournaments, including FIFA World Cup competitions.

What NASA and Adidas Are Demonstrating

Through a joint STEMonstration, NASA and Adidas are now presenting that science to a broader audience. The demonstration shows how the same physics governing motion in space also shape how a football curves, dips, and spins in front of millions of viewers on Earth. '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,' NASA noted in its communication on the experiment.

About the Trionda Ball

The name Trionda translates from Spanish as 'three waves,' a nod to the fluid geometry of its brand-new four-panel construction. The ball's red, green, and blue colour scheme pays homage to the three host nations — Canada, Mexico, and the United States — while iconography specific to each country adorns the surface: a maple leaf for Canada, an eagle for Mexico, and a star for the United States. Gold embellishments pay tribute to the FIFA World Cup Trophy.

According to FIFA, the four panels incorporate intentionally deep seams designed to produce optimal in-flight stability by ensuring sufficient and evenly distributed drag as the ball travels through the air. Embossed icons — visible only up close — are said to elevate grip when striking or dribbling in wet or humid conditions.

Connected Ball Technology

The Trionda also features a state-of-the-art 500Hz motion sensor chip that delivers real-time data on every element of the ball's movement. This information is transmitted directly to the video assistant referee (VAR) system, enhancing match officials' decision-making — including on offside calls. The technology builds on connected ball systems used in previous FIFA tournaments, representing a further step in the integration of sports science and officiating.

With the 2026 FIFA World Cup set to be the largest edition of the tournament in history, the Trionda's journey to the ISS underscores how cutting-edge research — conducted hundreds of kilometres above Earth — continues to shape the game played on the ground.
