Thousands of exoplanets have now been discovered with a huge range of bulk parameters and over the past three years TESS has been finding transiting exoplanets across the entire sky. Many of these have been around bright stars, meaning they will be excellent targets for atmospheric characterisation.

The Twinkle and Ariel space missions will conduct structured surveys of populations of exoplanetary atmospheres, using their wide, simultaneous spectral coverage to characterise these worlds. These missions will seek to link the chemistry of a planet to its formation environment and undercover trends between bulk parameters and atmospheric constituents.

These atmospheric surveys are benefiting from an increasing diverse list of potential targets and TESS is likely to provide hundreds of planets for these missions. I will present how many suitable targets TESS has found for each of these missions to date, comparing this to the expected yield of the mission and highlighting how TESS is supporting these future missions.
