The European Space Agency (ESA) has just declared that it has decided to launch the ARIEL (Atmospheric Remote Sensing Exoplanet Large-survey) mission during mid-2028. Also, ESA announced that ARIEL mission will last for 4 years.
According to the ESA statement, ARIEL is going “to address the fundamental questions of the formation of exoplanets and the formation and evolution of planetary systems, by examining the atmospheres of several hundred different planets orbiting different types of stars”.
Many mysteries in the Universe are still to be elucidated, according to the ESA, which also admits that no acceptable model exists today to connects the existence, the size, and the parameters of an exoplanet to the type of the star it’s orbiting.
“We do not know whether the chemistry of a planet is related to its formation environment, or whether the type of host star determines the physics and chemistry of the birth and evolution of the planet,” stated ESA representatives.
ESA researchers are optimistic that ARIEL will solve some of the mysteries surrounding exoplanets.
ARIEL will help ESA keep its competitiveness
On the other hand, ARIEL project will keep the European Space Agency to maintain its competitiveness in front of NASA which has Kepler that already successfully fulfilled its mission but, unfortunately, will soon remain without fuel.
However, NASA is a few steps in the front of ESA, as the US space agency will launch their TESS project next month and, later on, their James Webb Space Telescope, which both are set to study in-depth the already-found exoplanets, as well as to find new other exoplanets.
According to the mission’s official site, the ARIEL project “has been developed by more than 50 institutes from 12 European countries, which include the UK, France, Italy, Germany, the Netherlands, Poland, Spain, Belgium, Austria, Denmark, Ireland, and Portugal”.
In conclusion, ESA’s ARIEL exoplanet telescope will start its journey in mid-2028 and will have the mission to solve some of the mysteries surrounding exoplanets.
