For example, a team would form using the matchmaking system, formulate a collective plan via online conference, and then subsets of the team would implement the plan in their respective locations, each morning building upon the accomplishments of the subset working before them. Examples of Projects Several local teams approached their events with different perspectives, giving them a flavor unique to their culture and experience. For example, in Port- au-Prince, Haiti, high school students built simulators to explore and experience sustainable living. Jakarta, Indonesia, held satellite events in outlying villages where they judged projects over the phone. Kathmandu, Nepal, focused on engaging extremely low-income students with science, technology, engineering and mathematics. Toronto, Canada, engaged 150 primary school students in a parallel youth-focused challenge. In Athens, Greece, a team developed a modular spinach greenhouse designed to survive the harsh Martian climate. Thanks to the global matchmaking system, collaboration could occur across projects. The Growers Nation project sought to cultivate unused land in UK for local gardening, and the Pineapple Project to improve agricultural planning in Africa and South America. Jointly led by London- and San Francisco-based project managers, teams in Dominican Republic, UK, US, Chile and Kenya, as well as a number of virtual participants, collaborated to draw upon NASA satellite data to develop a unified agricultural, climate and topography database. These teams then built two apps: one for matching rural farmers to locally-suitable tropical fruit varieties and the other to help communities find land for community gardening. Pineapple Project went on to get awards at the USAID Food Security hackathon and Growers Nation is an ongoing funded effort by the UK Met Office. Communication Technology Developing a virtual community requires the right technology. Internet-based tools permitted communication, data-sharing and the exchange of ideas within and across Space Apps locations spanning the globe. Large and small IRC and Skype chat groups, for example, allowed for instant dissemination of information across the globe. Live streaming video allowed participants worldwide “virtual windows” into each other’s cities, making Space Apps a truly worldwide engagement for everyone. These tools also resulted in one-third of the final project submissions coming from teams that included at least one virtual member. Engaging the Masses The first Space Apps Challenge took place in 2012, in 25 locations around the world. In 2013, that number increased more than threefold with quadruple the number of attendees to include over 9,000 global citizens, making it the largest hackathon to date. Over 400 organizations participated, including six US federal agencies. Altogether, the event engaged approximately 60,000 person-hours of effort dedicated to addressing 58 challenges. Outcome Over the course of a few days, individuals collaborated to create software, hardware and data visualization innovations resulting in 770 solutions. Roughly fifteen times more mobile apps were developed over the course of the weekend than NASA itself had ever published. In addition, the event generated a great deal of enthusiasm and investment in exploration, thereby strengthening a community of explorers. In addition, the Challenge marked a shift in the way NASA interacts with the public and conducts its mission. Instead of limiting exploration and discovery to the governmental engineer, scientist, or astronaut, all citizens are empowered to contribute to a mission greater than themselves. Strong interest on the part of institutions as well as the development of an enthusiastic international community has paved the way for a third event which is intended for 2014. 6
