The University of Arizona is part of an international collaboration that is exploring how artificial intelligence can be harnessed to improve space operations, safety and sustainability.

Roberto Furfaro, professor of systems and industrial engineering and deputy director of the Space4 Center, is the UA co-principal investigator on the approximately $1.9 million initiative.

The project will accelerate the development of artificial intelligence technologies from concept, at early technology readiness levels, to adoption in the space sector. The partnership also paves the way for the creation of a new virtual Institute on AI for Space Safety & Sustainability aimed at attracting additional funding for further work.

"Our primary objective is to create dependable AI systems capable of managing the inherent uncertainties of space, which have very real policy, insurance and safety implications," Furfaro said. "The international team will develop AI solutions for analyzing space object behaviors, automating operations and ensuring the long-term preservation of space."

The University of Strathclyde Aerospace Centre for Excellence in Scotland is leading the project. Other partners include researchers from Massachusetts Institute of Technology; the University of Waterloo in Canada; the United Kingdom-based Alan Turing Institute and commercial space companies LMO and GMV; Nominal Systems in Australia; and Columbiad in Canada.

By processing vast amounts of data, AI can help predict and prevent collisions with space debris and predict space weather events, ensuring the secure operation of space assets such as satellites.

"AI's ability to make autonomous decisions in real time is crucial for maintaining the sustainability and security of space operations amid the growing complexity of the space environment," Furfaro said. "The students and postdoctoral fellows funded by the Space4 Center will be instrumental in data collection and analysis for creating sophisticated AI models for spacecraft protection."

The Space4 Center is developing research and education solutions to ensure that use of orbital space remains safe, secure and sustainable for decades to come.

Space around the Earth is becoming increasingly congested with both active satellites and space debris – defunct human-made objects, such as rocket bodies, and smaller items, such as astronauts' discarded toothbrushes and even flecks of paint. Each space mission leaves more debris, which could create hazardous conditions for astronauts and spacecraft in the future, or collisions that disrupt communications and other systems.

According to the U.S. Space Command, the amount of space debris has increased by 76% since 2019 to 44,600 objects.

What's more, between 20,000 and 100,000 new satellites are forecast to be launched into space over the next decade, potentially creating a major traffic jam in space if not managed in a sustainable way, said Vishnu Reddy, Space4 Center director and UA professor of planetary sciences.

The yearlong AI project comes under the second phase of approximately $25.3 million in International Bilateral Fund investments by the UK Space Agency, which will help UK organizations link up with global experts. Phase 1 of the project is focused on establishing a clear vision to fast-track the advancement of AI technologies that are critical for space operations.
