ESA's Ariel Mission with Prof. Giovanna Tinetti | On Things to Come

New webinar of the ISSI-BJ On Things to Come series on ongoing and future space missions. The topic is the Ariel mission of the European Space Agency, and the lecture will be given by Prof. Giovanna Tinetti (UCL).

Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA’s Cosmic Vision program to be launched in 2029. During its 4-year mission, Ariel will study what exoplanets are made of, how they formed and how they evolve, by surveying a diverse sample of about 1000 extrasolar planets, simultaneously in visible and infrared wavelengths. It is the first mission dedicated to measuring the chemical composition and thermal structures of hundreds of transiting exoplanets, enabling planetary science far beyond the boundaries of the Solar System. The payload consists of an off-axis Cassegrain telescope (primary mirror 1100 mm x 730 mm ellipse) and two separate instruments (FGS and AIRS) covering simultaneously 0.5-7.8 μm spectral range. The satellite is best placed into an L2 orbit to maximize the thermal stability and the field of regard. The payload module is passively cooled via a series of V-Groove radiators; the detectors for the AIRS are the only items that require active cooling via an active Ne JT cooler. The Ariel payload is developed by a consortium of more than 50 institutes from 17 ESA countries, which include the UK, France, Italy, Belgium, Poland, Spain, Austria, Denmark, Ireland, Portugal, Czech Republic, Hungary, Germany, the Netherlands, Norway, Sweden, Estonia and a NASA contribution.

About Prof. Giovanna Tinetti
Professor Giovanna Tinetti is the Head of Group of Astrophysics at University College London and Director of the UCL Centre for Space Exo-chemistry Data at Harwell. She is the Principal Investigator of Ariel, the European Space Agency's next medium-class (M4) science mission to be launched in 2029. She is also co-founder and co-director of Blue Skies Space Ltd, which aims at creating new opportunities for science space satellites. Select appointments and achievements include Principal Investigator of the European Research Council-funded program Exo-Lights, Institute of Physics Moseley Medal 2011 and NASA Group Achievement Award 2009. Awarded a PhD in Theoretical Physics from the University of Turin in Italy in 2003, Giovanna Tinetti has continued her academic career as NASA Astrobiology Institute Fellow at Caltech/JPL and then as European Space Agency Fellow in Paris, before moving to UCL in 2007 as STFC Aurora Fellow and then Royal Society URF Fellow. Prof. Tinetti has authored / co-authored over 200 research papers and has delivered over 260 talks, seminars and public lectures internationally.
