127Teams

Invent Your Own Challenge

Participants are invited to create their own challenge to tackle, but these are not eligible for Global Judging.
139Teams

Let It Go (Without A Bang)

Letting things go in space, or separating spacecraft parts, is often a violent, high-shock event. Your challenge is to design a mechanical separation device that can cut a parachute reefing line, a bolt for an adapter ring, or a cable, or release two parts from each other smoothly in space without pyrotechnics.
243Teams

Leveraging AI/ML for plastic marine debris

Marine debris is one of the most pervasive threats to the health of coastal areas, oceans, and waterways. Your challenge is to leverage Artificial Intelligence/Machine Learning to monitor, detect, and quantify plastic pollution and increase our understanding about using these techniques for this purpose.
122Teams

Lunar Surface Operations: Real-Time Collaboration

As astronauts collect data on the Moon, NASA and the worldwide scientific community will be documenting and reviewing the information in real time. Your challenge is to create an application to allow NASA flight controllers and the broader scientific community to collaborate and compare notes on lunar mission data as it is collected.
220Teams

Mapping Space Trash in Real Time

The increasing amount of debris orbiting Earth could potentially limit our access to space, impacting not only exploration efforts, but routine aspects of our life on Earth. Your challenge is to develop an open-source geospatial application that displays and locates every known debris object orbiting Earth in real time.
84Teams

Measuring the Value of Earth Observations

Information from Earth-observing satellites is used to make decisions that benefit society and the environment, but it can be challenging to document how this information leads to improved outcomes and to measure these improvements. Your challenge is to describe how Earth observations inform a specific decision that improves outcomes for society and propose a strategy for measuring these benefits.
150Teams

Near-Space Near You!

Develop a lesson-plan and bill of materials which teach students how to build a low-cost high-altitude balloon capable of reaching near-space.
56Teams

Ontologies and Interactive Network Visualizations

Tens of thousands of NASA datasets are publicly available online, but with so many files available, how can potential users determine those that will meet their needs? Your challenge is to (1) create an ontology to integrate descriptions of disparate NASA data sets, and (2) develop an interactive network visualization to depict relationships among those data sets.
153Teams

Planetary Lander Video Game

NASA’s near-term space exploration plans include returning to the Moon and future plans include landing a crew on Mars. Your challenge is to create an inspiring and educational video game or interactive 3D model to simulate a landing on the Moon or Mars!
64Teams

Seeing the unseeable - Viewing Bugs from Space

Our lives hinge on the wellbeing of insects; at the same time, insect biodiversity is disproportionately affected by human actions. Your challenge is to develop innovative ways to advance our ability to detect insect life, track and predict change over time, and communicate that information to scientists and society to combat the loss of insect biodiversity.
187Teams

Space for Change

Marginalized communities are often disproportionately impacted by environmental hazards. Your challenge is to use NASA's Earth observation data to: 1) identify regions where such environmental injustice occurs, and 2) design implementable solutions that enable equitable outcomes.
155Teams

Space Quest: The Game

Your challenge is to create a game that teaches players about space from the perspective of the architectures and challenges of exploration. The setting can be anything, from the past, to the future, with destinations either in our solar system, or beyond.
193Teams

SuperpowEARTH

The Earth has many abilities and processes that help keep the Earth and its inhabitants alive. If the Earth had a superpower that could help or possibly eliminate something that harms the planet in general, such as climate change, what would the superpower be? What would the Earth be able to do?
216Teams

The Trail to Mars: Can You Keep Your Crew Alive

Long-distance space travel comes with a multitude of health risks, but it is difficult to imagine the combined effects of these risks, especially for those who are not fluent in NASA jargon. Your challenge is to create an educational game for middle schoolers (approx. ages 10-14) that focuses on keeping an avatar alive and healthy during a voyage from Earth to Mars and back, and that identifies the most difficult challenges and the biggest risks involved in human spaceflight.
