Your challenge is to create a new video game that uses NASA Earth data, providing players a novel way to interact and have fun with NASA Earth data. What you create can inform, educate, inspire, or simply provide an enjoyable experience for players – the Earth is your stage!

You are a newly appointed Regional Green Engineer. Your challenge is to develop green infrastructure solutions for complex challenges in water management and risk reduction. Create a tool to assess the characteristics of an urban or rural area of your choice, and integrate green infrastructures, or nature-based solutions, into that region’s development plans to 1) reduce flood and/or drought risk, 2) establish sustainable land use practices, 3) support water management, and/or 4) produce local economic opportunities.

Your challenge is to design and build an innovative platform to integrate satellite data and information about vulnerable populations and environmental hazards in order to identify the most at-risk populations. Be creative and think outside the box. How will you identify those people that are often missed, but need aid the most?

NASA builds and operates numerous satellite and airborne missions that deliver critical measurements and data to the world’s science community. Your challenge is to develop a tool that enables people to identify NASA satellites and satellite instruments as they fly over their locations on Earth. Help people explore the data and applications coming from the instruments overhead!

NASA’s open data sources hold an abundance of imagery. Mapping that imagery to a digital globe makes the data interactive and may enable people to discover relationships among ecosystem phenomena. Your challenge is to develop a digital globe web-app that visualizes Earth science data using NASA’s Web WorldWind.

Your challenge is to develop creative solutions that use Earth observations to address the United Nations’ Sustainable Development Goals and foster sustainable development worldwide. Use NASA and other Earth observing satellites’ data as well as information generated by crowd-sourcing and in-situ measurements to create practical applications that support environmental and societal policy across water, health, food security and/or land use domains.

Your challenge is to create an application that leverages NASA's near-real-time and archival wildfire datasets along with other tools to support firefighting and fire mitigation efforts. This challenge builds on last year’s challenge of the same name by calling for innovative ideas and apps that focus on how to engage and enable citizens to assist with the entire firefighting and fire mitigation process.

Your challenge is to integrate NASA data, ground-based air quality data, and citizen science data to create an air quality surface that displays the most accurate data for a location and time. Create algorithms that select or weight the best data from several sources for a specific time and location, and display that information.

Your challenge is to solve the mystery behind algal blooms! What factors cause blooms in some water bodies but not others, and how can we better predict their occurrence to prevent harm to aquatic and human life?

Your challenge is to examine existing space and Earth projects and systems and adapt them into specific technologies that help stabilize or improve the Earth’s weather, and/or eliminate processes that cause global warming. Your solution could be a technology, a movement, an idea – let your imagination have no bounds!

Your challenge is to explore planetary surface types around the world and design new data products for types of terrain beyond ice sheets, sea ice, land, ocean and inland water elevation.
