Six months ago, First Lego League challenged tens of thousands of students across the world to find a way to make astronauts lives better while they’re in space.

In Gwinnett, 72 teams of elementary school students accepted that challenge, and on Friday, more than 22 of those teams displayed their solutions for the public to see at Duluth’s Infinite Energy Forum as part of the 2019 Gwinnett County Regional Science, Engineering and Innovation Fair.
