Project Hail Mary LEGO Set Wins Guinness Record After Near-35 km Stratosphere Flight

The certified record turns a film tie-in into a showcase of real engineering.

Overview

  • The Project Hail Mary LEGO Icons set, launched from Gwynedd County in Wales on March 20, 2026, reached 34,988 metres in the stratosphere.
  • UK firm Sent Into Space built a custom platform with cameras and GPS, flew it on a high-altitude balloon, and guided an over eight-hour mission that ended under a parachute.
  • Guinness recognized the “highest altitude launch and retrieval of a LEGO set” after a clean, intact recovery, with an official certificate later presented in Las Vegas.
  • Sony Pictures UK and Amazon MGM Studios staged the flight as a release-week promotion, and the tie-in LEGO set is on sale for £99.99.
  • Coverage this week highlighted the record and shared playful doubts about the landing, while officials maintained the set returned intact.
