Scientists develop zero gravity space fuel system

The University of Surrey, in partnership with Atout Process Ltd, is pioneering the development of a revolutionary fuel gauge called the Smart Tank for Space (SMARTTS).

The cutting-edge technology will undergo testing aboard the International Space Station (ISS), marking a significant stride in space exploration.

The SMARTTS technology can precisely measure tank capacity in zero gravity through the utilization of advanced electrical sensors. The construction of the tank is scheduled for completion in 2024, with delivery to the space station slated for 2025.

Atout Process Ltd has engaged the expertise of space engineers from the renowned Surrey Space Centre at the university. Leveraging the advanced facilities on-site, they are collaborating to propel the development of innovative space-related projects.

Surrey stands as a key hub for space sciences in the UK, underscored by the university’s significant achievement of securing £400,000 in funding from the UK Space Agency in February of the preceding year.

Professor Keith Ryden, director of Surrey Space Centre, said: “Gauges like those used in cars don’t work in zero gravity, so alternative techniques are used in space which rely on estimates and calculations.

“However, errors can accumulate and there’s no real-time information, so mission designers have to factor in extra reserves of fuel, with significant associated costs.

“SMARTTS could be a real game-changer in the space sector, saving money and opening doors to new industries, and we’re keen to see how they operate in orbit.”
