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

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.
