letzSCIENCE invites people to experience the beauty of science in augmented reality (AR). Drive a rover on the Moon, dive into the microscopic world, make plasma and much more. All experiences tell a story about a science topic that researchers in Luxembourg are working on. This is part of a campaign by the Luxembourg National Research Fund (FNR), the main funder of research activities in the country. The goal of the letzSCIENCE is to raise awareness of FNR-supported research in Luxembourg, in an easy-to-understand manner that is accessible and engaging to everyone.
