TheNASA International Space Apps Challenge is the a global annualhackathon. This two-day event provides an opportunity for participants to utilizeNASA's free andopen data and its Space Agency Partners' space-based data to address real-world problems onEarth and inspace.
During the hackathon, NASA Space Apps Challenge participants around the world gather at hundreds of in-person and virtual local events to address challenges submitted by NASAsubject matter experts. In the early years, NASA Space Apps was primarily focused on space science and technology. However, in 2017, NASA Space Apps moved to the NASA Earth Science Division and expanded to include Earth science and technology. Today, NASA Space Apps features arts and humanities alongside technology challenges, building a more inclusive program with broader appeal. These challenges range in complexity and topic, tasking participants with everything from creating artistic visualizations of NASA data to conceptualizing and developing informational apps and software programs.
The program, formerly run by NASA's Office of the Chief Information Officer, is part of NASA's Science Mission Directorate and is a part of theOpen Government Initiative founded underPresident Barack Obama. It also fulfills the United States’ commitments to theOpen Government Partnership. The United States released its National Action Plan for the Open Government Partnership in September 2011, including a commitment to hold the NASA International Space Apps Challenge to “promote innovation through international collaboration”. Today, NASA Space Apps is managed by the Earth Science Division, Science Mission Directorate, at NASA Headquarters in Washington, DC.
NASA Space Apps has engaged 373,000+ registrants from 185+ countries/territories.
NASA collaborates with international Space Agency Partners on the NASA Space Apps Challenge to encourage more extensive global collaboration and provides a broader platform for participants to contribute to the fields of Earth and space science and technology through NASA Space Apps.
After the NASA Space Apps Challenge concludes, each Local Event nominates teams with the top projects for Global Judging. The number of nominees depends on the number of projects submitted at each event. Local Events also may select an additional team for the Local People's Choice Award. Teams are also selected from the Universal Event to proceed to Global Judging.
Each year, NASA attempts to invite Global Winners and Local Leads from winning locations to a NASA spacecraft launch. Global Winners are also featured on the NASA Space Apps website and social media.
In 2013,Mars Exploration Program offered the NASA Space Apps 2012 Global Winners the opportunity to attend the launch ofMAVEN, a Mars Orbiter.Kennedy Space Center also provided winners of their challenges that opportunity. The launch occurred on November 18, 2013, on anAtlas V 401 fromCape Canaveral Air Force Station.
NASA Space Apps 2013 Global andKennedy Space Center winners attended the OrionExploration Flight Test 1 launch. The launch scrubbed once on December 4 before occurring on December 5, 2014, on aDelta IV Heavy fromCape Canaveral Air Force Station.
NASA Space Apps 2014 Global and the overallKennedy Space Center winners attended the viewing opportunity for theCygnus CRS OA-4 launch, taking cargo and experiments to theInternational Space Station. The launch scrubbed twice on December 3 and 4; it occurred on December 6, 2015, on anAtlas V 401 fromCape Canaveral Air Force Station.
NASA Space Apps 2015 Global and the overallKennedy Space Center winners were invited to attend the launch ofOSIRIS-Rex, visiting the asteroidBennu. The launch occurred on September 8, 2016, on anAtlas V 411 fromCape Canaveral Air Force Station.
NASA Space Apps 2016 Global Winners were invited to attend the launch ofTDRS-M, a NASATracking and Data Relay Satellite operated by theSpace Communications and Navigation Program (SCaN). The mission experienced delays in weeks leading up to launch on August 18, 2017, on anAtlas V 401 fromCape Canaveral Air Force Station.
In 2017, Global Winners were invited to attend the launch of TDRS-M, a NASA Tracking and Data Relay Satellite operated by the Space Communications and Navigation Program (SCaN). The mission experienced delays in weeks leading up to launch on August 18, 2017, on an Atlas V 401 from Cape Canaveral Air Force Station.[41]
NASA Space Apps 2018 Global Winners were invited to Kennedy Space Flight Center to attend the launch of the Falcon 9 rocket as part of SpaceX CRS-18, a Commercial Resupply Service mission to the International Space Station.
In 2019, 2020, and 2021, invitations to NASA launches were postponed because of the COVID-19 pandemic. In 2021 and 2022, Global Winners were invited to a virtual celebration with NASA representatives. In 2023-2025, Global Winners were invited to NASA Headquarters in Washington, DC and Goddard Space Flight Center in Greenbelt, MD for an in-person celebration.

In 2017 the NASA Space Apps Challenge was hosted by a Local Lead in Melbourne Australia and several other Australian cities also competed. Speakers included Andrew Aldrin, son of American astronautBuzz Aldrin, who works in the launch and education areas of the space industry. Aldrin fascinated the audience by discussing the ‘new’ space industry that seeks more entrepreneurial approaches to innovation. He wanted to see more investment in propulsion from the Moon and in space manufacturing, both of which could address the ongoing problem of orbiting space junk.
Main Stage Location(s): Palo Alto, California led by the Local Lead Irena Chaushevska and New York City, New York led by the Local Lead Joseph Spens.
