The NASA Space Apps Challenge is an intense 48-hour international hackathon hosted simultaneously in over 100 cities around the world. This is the second year the Waterloo hackathon will be held at Communitech. This event is aimed at solving some of NASA’s most complex challenges. They enable participants to solve these challenges by making their enormous amounts of data open and available through the openNASA initiative.  Some of these challenges include better measuring the Earth’s air quality, better understanding the impact of climate change, and even finding better ways to monitor the health of astronauts.
