Unravel the story of planets within our galaxy
Explore our seven-year space science mission, Twinkle
A new class of Science Satellite
Twinkle is a seven-year space science mission that will unravel the story of planets within our galaxy.
Collaborative international surveys will deliver visible and infrared spectroscopy of thousands of targets, enabling scientists to produce transformative research on exoplanet atmospheres, solar system objects, stars and stellar discs.
Scientists worldwide can join the mission and shape its science agenda through a simple membership programme

Technical Specifications
Twinkle is being designed in collaboration with leading satellite and instrument manufacturers Airbus and ABB. The high-heritage approach to the design and component selection will deliver a high-specification astronomy satellite within the short timeframes usually associated with commercial satellites.
The satellite will operate in a low-Earth, Sun-synchronous polar orbit, maximising opportunities for science observations along the ecliptic plane.

Survey Programmes
Delivering visible and infrared spectroscopy of thousands of objects within and beyond our solar system
Each survey aims to encourage worldwide scientific collaborations leading to high-impact publications by providing powerful population studies in two science areas: exoplanets and solar system bodies.
Extrasolar Science
Twinkle will provide high-quality infrared spectroscopic characterisation of the atmospheres of a population of exoplanets, covering a wide range of planetary types.
Solar System Science
Twinkle will study the surface composition of thousands of small bodies within our Solar System
