What is Space Apps?

The NASA International Space Apps Challenge (Space Apps) is an international hackathon for coders, scientists, designers, storytellers, makers, builders, technologists, and others in cities around the world, where teams engage the National Aeronautics and Space Administration’s (NASA’s) free and open data to address real-world problems on Earth and in space.

For one weekend each October, participants from around the world come together over a 48-hour period to solve challenges submitted by NASA personnel. After the hackathon, project submissions are judged by space agency experts and winners are selected for one of 10 Global Awards.

Space Apps introduces problem-solvers worldwide to NASA’s free and open data. By using NASA data to solve each year’s challenges, Space Apps teams learn about NASA’s data, and share in the creation and application of the knowledge that results.

Space Apps also inspires collaboration, creativity, and critical thinking. Our mission is to leverage this interest to encourage the growth and diversity of the next generation of scientists, technologists, designers, storytellers, and engineers.

Who Should Participate in Space Apps?

At Space Apps, there's always space for one more.

The common thread among Space Apps participants is that you are interested in space science and exploration, that you are creative, and that you want to solve problems.

As a part of Space Apps, you are part of a global hackathon community that embraces collaboration across borders, sectors, and cultures to bring about paradigm-shifting innovation.

Who manages Space Apps?

Space Apps is a NASA-led initiative organized in collaboration with Booz Allen Hamilton, Mindgrub, SecondMuse, and the NASA Open Innovation Applied Sciences Program.

The Space Apps Global Organizing (GO) Team is composed of members of these different organizations. Click here to meet the team.

Space Apps also relies on a vast community of partners and volunteers, including space agency partners and “Local Leads” from around the world. Local Leads organize and host events in their local communities.

While the Local Lead application is closed for the 2021 event, please complete this form if you are interested in being a Local Lead for the 2022 event and want to be notified when the Space Apps 2022 Local Lead Application opens.
