NASA Space Apps Challenge, the world’s largest global hackathon, has opened registration for its 14th edition, taking place over the weekend of October 4–5, 2025, in Bucharest, Cluj-Napoca, and hundreds of other cities worldwide. So far, over 373,000 participants from 185 countries and territories have joined previous editions. The hackathon is open to all Earth and space science enthusiasts—regardless of age or professional background, according to Romania Journal.
The mission of the NASA Space Apps Challenge is to foster collaboration, creativity, and critical thinking; to encourage interest in Earth and space exploration; to raise global awareness of NASA data; and to help develop the next generation of scientists, engineers, technologists, and designers.
Over a 48-hour period, participants will gain access to NASA’s open data and work together to develop solutions to real-world challenges—both on Earth and in space. The event is open to programmers, scientists, engineers, storytellers, designers, and anyone passionate about innovation and discovery.
Participants under 18 must be registered by a parent or legal guardian and accompanied by them during the event.

Theme for NASA Space Apps Challenge 2025: “Learn, Launch, Lead”
Winning teams from the local editions in Bucharest and Cluj-Napoca will compete in the global competition, with a chance to be invited to a NASA center for a special celebration event.
“Through NASA Space Apps Challenge, people who care about our planet and space can directly engage with NASA’s missions. In 2024 alone, 93,000 participants joined—nearly half the total number across all previous editions. The growth shows how many people are eager to find real solutions to pressing global challenges,” said Diana Iosu, founder of DiFine PR, organizer of the Bucharest edition.
“The space economy is becoming a vital part of the global tech market, from SpaceX’s low-orbit satellites to the growing defense and drone industries. At ROTSA, we aim to help Romanian entrepreneurs stay competitive and seize these opportunities. This year’s theme—‘Learn, Launch, Lead’—captures the spirit of any impactful initiative,” added Diana Ardelean, Executive Director of ROTSA, organizer of the Cluj-Napoca edition.
“NASA Space Apps Challenge is more than a hackathon—it’s a global movement encouraging young minds, curious citizens, and changemakers to tackle humanity’s biggest challenges. Every year, Romania’s vibrant community of innovators impresses with how they use science for public good. The theme ‘Learn, Launch, Lead’ is about continuous learning, bold action, and collaborative leadership,” said Dr. Ulpia-Elena Botezatu, Space Policy Officer at the Romanian Space Agency (ROSA) and Chair of the UN COPUOS Scientific and Technical Subcommittee.
This year’s challenge categories will be announced on August 21, and they typically focus on real-world issues such as climate change, agriculture, wildfire management, planetary science, and space mission optimization.
