The Ariel Space Mission

✓The European Space Agency (ESA) has formally adopted Ariel.

✓Ariel (Atmospheric Remote-sensing Infrared Exoplanet Large-survey) will be launched in 2029.

✓ It will perform a large-scale survey of over a thousand exoplanets over a period of four years.
✓ The explorer that will study the nature, formation and evolution of exoplanets.

✓Ariel is the first mission of its kind dedicated to measuring the chemical composition and thermal structures of hundreds of exoplanets.

✓It will also help to answer one of the key questions of ESA’s Cosmic Vision Plan, which is, “What are the conditions for planet formation and the emergence of life?”.

✓The search for exoplanets is driven by the possibility that life may exist beyond Earth and even if there is no evidence for this, scientists believe that their hunt for an answer will reveal details about where humans came from and where we’re headed.

✓As of now the existence of more than 4,000 exoplanets is considered confirmed, while there are thousands of other candidate exoplanets that need further observations to say for certain if they are exoplanets.
