ESA moving forward with plans to explore exoplanets by end of 2020s
Nov. 12 (UPI) -- The European Space Agency said Thursday it's moving forward with an ambitious mission to study exoplanets and plans to start by the end of the decade. ESA said it will choose a contractor to build a state-of-the-art spacecraft that can study various exoplanets for composition and clues as to how they evolved. Advertisement The studies are part of the ESA's Ariel mission, which it says will launch in 2029. Ariel, short for Atmospheric Remote-sensing Infrared Exoplanet Large-survey mission, will be the first to attempt to measure chemical composition and thermal structures of distant exoplanets. "Ariel will enable planetary science far beyond the boundaries of our own solar system," Gunther Hasinger, ESA director of science, said in a statement. "The adoption of Ariel ceme...
