In 2007, a small group of people began an intentional, collaborative experiment in open, transparent, and direct communication about your space program. Our goal was to enable your direct participation in exploring and contributing to NASA’s mission.

Many of us have since begun new adventures. This site will remain as an archive of the accomplishments of the openNASA experiment.

WASHINGTONNASA and government agencies worldwide will host the second International Space Apps Challenge on April 20-21, with events across all seven continents and in space.

Participants are encouraged to develop mobile apps, software and hardware, data visualization, and platform solutions that could contribute to space exploration missions and help improve life on Earth.

The two-day event will provide an opportunity for government to harness the expertise and entrepreneurial spirit of citizen explorers to help address global challenges. During the event, representatives from NASA and other international space agencies will gather with scientists and participants to use publicly released open data to create solutions for 50 software, hardware and visualization challenges, including robotics, citizen science platforms and applications of remote sensing data. Challenges selected to be worked on during the event will be published online prior to the event.

The 2012 challenge engaged more than 2,000 participants who collaborated on more than 100 open source solutions to 71 featured challenges.

What sets apart the International Space Apps Challenge from other events is that this is a collaborative opportunity to engage people from all over the world to participate in space exploration and develop state-of-the-art technology to improve life on Earth and in space,” said Nick Skytland, program manager of NASA’s Open Innovation Program.

We are excited to connect with explorers living and working at McMurdo Station in Antarctica and onboard the International Space Station.

In addition to the physical locations noted above, there will be a limited number of satellite locations that are smaller, more informal events but open for public participation. As always, virtual participation is available to anyone who would like to connect and contribute remotely. Registration for citizen participation will open in March for the main events, satellites and virtual.
