## Eligibility & scope

Sandpit to co-create small satellite Earth observation mission concepts combining innovative sensors, data streams and cross-sector technologies for UK sovereign capability, national security, societal benefit and economic growth. Applicants must be based at a UK research organisation eligible for UKRI funding; UK businesses, government departments, third sector organisations and international organisations are not eligible to apply directly but may participate as project partners.

## Summary

The Small Satellite Missions Sandpit, funded by UKRI, pays for Phase 0 study funding, up to £1.87 million at 100% FEC with UKRI covering 80%, to develop small satellite Earth observation mission concepts. Applicants must come from UK research organisations eligible for UKRI funding, attend an interactive sandpit to form consortia, and combine novel sensors, data streams and cross-sector technologies aimed at UK sovereign capability and national security. This is a one-off call, with full applications made only by invitation following sandpit participation.

## Who should apply

- Researchers at UK research organisations eligible for UKRI funding
- Teams working on small satellite Earth observation sensors or mission concepts
- Applicants willing to form consortia at the sandpit event itself
- Projects able to start by 1 May 2027 within an 11-month study
- UK businesses, government bodies and third-sector groups joining as project partners rather than lead applicants

## Key dates

- Expression of interest deadline: 25 November 2026, 16:00 UK time
- Invited full application deadline expected 18 March 2027 (by invitation only, following sandpit co-creation)
- Projects must start by 1 May 2027, for up to 11 months

## Tips for applicants

- Consortia are formed at the sandpit itself, so apply for sandpit attendance even without a pre-formed team, the co-creation process builds the partnership.
- A signed collaboration agreement between partners must be in place before grant start, so start those conversations early once sandpit groups form.
- Frame the mission concept around UK sovereign capability and national security relevance, as these are explicit scope priorities, not just scientific merit.
