British researchers have launched a UK Space Agency‑funded micro‑laboratory carrying Caenorhabditis elegans to the International Space Station. The payload lifted off from Kennedy Space Center at 12:41 BST on 11 April 2026 aboard NASA’s Northrop Grumman Commercial Resupply Services‑24 mission, providing a new platform for in‑orbit biology in support of future lunar operations.

As set out by the UK Space Agency, the experiment is led by the University of Exeter, with hardware engineered by the University of Leicester at Space Park Leicester and mission support from Voyager Space Technologies. Once installed on an external platform by the station’s robotic arm, the unit will expose the organisms to vacuum, radiation and microgravity for up to 15 weeks under remote control from Earth.

Known as the Fluorescent Deep Space Petri‑Pods (FDSPP) or ‘Petri Pod’, the self‑contained unit measures about 10×10×30 cm and weighs roughly 3 kg. It houses 12 miniature life‑support chambers, four with active fluorescent and white‑light imaging, each maintaining temperature, pressure and a small air volume, with food and water delivered via an agar carrier.

Researchers will assess the worms’ health through stills and time‑lapse video, while on‑board sensors collect temperature, pressure and accumulated radiation dose data for downlink to the ground. The approach allows in‑orbit observation of biological responses rather than reliance only on sample return. (gov.uk)
The agency positions the study against known risks of long‑duration human spaceflight including bone and muscle loss, fluid shifts that can affect vision and radiation‑related genetic damage. The timing follows NASA’s Artemis II mission, which completed a roughly 10‑day crewed loop around the Moon with splashdown on 10 April 2026. (gov.uk)
Execution is split across academic and industry partners: biology led by Dr Tim Etheridge at the University of Exeter; flight hardware designed and built at Leicester; and mission and launch interfaces provided by Voyager Space Technologies. Early images from orbit will be used to validate instrument behaviour before extended exposures commence. (gov.uk)
Ministerial messaging connects this work to the Government’s funding stance. In a speech on 4 March 2026, Liz Lloyd, Minister for the Digital Economy and the DSIT minister with responsibility for space, confirmed more than £2.8 billion for the UK Space Agency over the next four years and signalled a focus on assured access to space, satellite communications, in‑orbit servicing and space domain awareness.

The same address outlined plans to bring UK Space Agency functions into DSIT and to establish a Space Ministerial Forum to coordinate civil and defence decision‑making. For research organisations and SMEs, that direction implies a tighter link between grant funding, commercialisation and international partnerships on hosted payloads. (gov.uk)
UK Space Agency documentation also emphasises the value of running complex biology at miniature scale and comparatively lower cost. Demonstrating that capability on the ISS broadens options for future UK participation in external payloads and, in time, biology packages linked to Artemis operations. (gov.uk)
Commissioning will begin inside the ISS before the payload is moved outside for up to 15 weeks of exposure, with data relayed to ground teams throughout. Findings are expected to inform countermeasure development and mission planning for sustained lunar activity in the Artemis era. (gov.uk)
