Since its inception in 2012, the International Space Apps Challenge, a part of NASA’s Earth Science Division, has become the world’s largest global hackathon, engaging thousands of citizens each year across the globe to work with NASA in building innovative solutions challenges we face on Earth and in space using open source data. Space Apps inspires local innovation communities in cities across six continents to convene, ideate and build. Diverse and collaborative teams of technologists, scientists, designers, entrepreneurs, and others work together in a 48-hour sprint to develop answers to some of the most pressing challenges facing planet Earth using NASA data. Over 15,000 citizens from 61 countries and in 161 cities around the world participated in the 2016 International Space Apps Challenge. Space Up Club established within the Private Higher School of Technologies & Engineering ‘’TEK-UP’’ will host the Nasa Space Apps Challenge Tunisia in its third edition on 29th – 30th April 2017 .
