The EnVision Phase A study assessment study has been concluded and the related report, also known as the “yellow book”, has been prepared by the EnVision Science, Instruments and ESA Teams. It gives a complete description of the EnVision mission to Venus at the end of the phase A from a scientific, technical and operational points of view. It also reflects the (hard) work of tens of people across Europe and in the US in the last 3 years, and show what can be achieved when combining the best of science and engineering worlds.
RSLab is deeply involved in EnVision as Lorenzo Bruzzone is the Lead for the Sub-surface Radar Sounder (SRS) instrument and Francesca Bovolo is a member of the ESA Science Study Team. Moreover many RSLab members have cotributed to the Phase A study of the SRS instrument.
The yellow book will be the basis for an independent scientific evaluation of the mission which is just starting – in parallel the EnVision study has also entered an extensive review by ESA (called the “Mission Selection Review”) to confirm its technical and programmatic feasibility.
The outcomes of these two parallel processes (scientific assessment and mission selection review) will feed the decision by ESA in June 2021 on the next Medium-class mission (“M5”) within ESA’s Cosmic Vision science programme , among the two remaining candidates : Theseus and EnVision.
