In 2012, New York City became a founding site for NASA's Space Apps Challenge, a worldwide hackathon that has enabled historic global collaboration between volunteers, private companies, NGOs, and government agencies. Since its founding, our Space Apps NYC team has locally organized five hackathons and two conferences, has hosted NASA's Global Mainstage two years in a row, and has grown our diverse space hacker community to the largest and most active chapter with over 1,800 hackers! Also, by partnering with Space Apps Brooklyn, we are expanding to more boroughs in order to run multiple locations for the hackathon and bootcamp.
