Tiny nematodes, supported by Midlands-built hardware, could unlock secrets of long-duration spaceflight
British scientists are sending dozens of microscopic worms into space today in an experiment they hope will help protect astronauts on long missions to the Moon and beyond.
The project, known as the Fluorescent Deep Space Petri-Pod (FDSPP), is a miniature laboratory designed to study how living organisms respond to the harsh conditions of space, including microgravity, vacuum and radiation.
It is led by the University of Exeter, with the hardware engineered and built by the University of Leicester at Space Park Leicester, and funded by the UK Space Agency. Voyager Space Technologies is managing the mission.
The experiment launched on April 8 aboard a cargo vehicle from Kennedy Space Center in Florida. Once at the International Space Station (ISS), it will initially remain inside before being mounted on the exterior by a robotic arm, exposing the worms to the full rigours of space for up to 15 weeks. Researchers on Earth will control and monitor the setup remotely.
This comes shortly after NASA’s Artemis II mission, which sent four astronauts on a 10-day journey around the Moon – a key step towards returning humans to the lunar surface for the first time since 1972 and establishing a long-term base.

Tackling space’s toll on the human body
Microgravity can cause bone and muscle loss, fluid shifts and vision problems, while radiation increases the risk of genetic damage and cancer.
The tiny “C. elegans” nematode worms, just 1mm long and a staple of Earth-based biological research, share many genes with humans, making them ideal models for studying these effects.
Space Minister Liz Lloyd said: “It might sound surprising, but these tiny worms could play a big role in the future of human spaceflight.
“This remarkable mission, backed by government funding, shows the ingenuity and ambition of UK space science, using a small experiment to tackle one of the biggest challenges of long-duration space travel: protecting human health.
“As we prepare for a new era of exploration, including future missions to the Moon, research like this will help astronauts stay healthy and return home safely. It’s a great example of how we’re driving innovation to grow the economy and keep the UK at the forefront of future technologies.”
Dr Tim Etheridge, from the University of Exeter, said: “NASA’s Artemis programme marks a new era of human exploration, with astronauts set to live and work on the Moon for extended periods for the first time.
“To do that safely, we need to understand how the body responds to the extreme conditions of deep space. By studying how these worms survive and adapt in space, we can begin to identify the biological mechanisms that will ultimately help protect astronauts during long-duration missions, and bring us one step closer to humans living on the Moon.”
Compact innovation with big ambitions
The self-contained Petri Pod measures roughly 10x10x30cm and weighs about 3kg. It houses 12 experimental chambers, four of which can be imaged using fluorescent and white light cameras. Each chamber maintains temperature, pressure and a breathable air volume, with worms receiving food and water via an agar carrier.
Scientists will track the worms’ health through glowing fluorescent signals and time-lapse video, while sensors record temperature, pressure and radiation dose.
Professor Mark Sims, project manager at Leicester, said: “FDSPP is Leicester’s first major microgravity life sciences project, and it has been both an interesting and challenging instrument to design and build. The project builds upon previous work with Tim Etheridge and the University of Exeter.
“Having now delivered the experiment to Voyager Space Technologies, who provide the interface to NASA and its flight on the International Space Station, the project team at Leicester look forward to seeing the first images from orbit.
“We hope this will contribute to our understanding of the microgravity environment, and we’re excited about the potential to further develop the instrument concept in the future.”
The mission also demonstrates that complex biology experiments can be conducted in space at miniature scale and relatively low cost, paving the way for more accessible research in support of humanity’s deep-space ambitions.
