The International Space Apps Challenge is an international mass collaboration focused on space exploration that takes place over 48-hours in cities around the world. The event embraces collaborative problem solving with a goal of producing relevant open-source solutions to address global needs applicable to both life on Earth and life in space. This year we have over 25 challenges in four areas: Earth, Outer Space, Humans and Robotics. NASA is leading this global collaboration along with a number of government collaborators and over 100 local organizing teams across the globe.
