The JUICE mission carries a subsurface radar (RIME) of which the deployment boom has been developed under ESA responsibility as a project/spacecraft contributed item to the payload. With the exception during the early deployment and a Venus flyby the JUICE mission experiences a rather cold environment. The antenna length of RIME is around 16 m corresponding to a centre frequency of 9 MHz. Theproposed subsurface radar of EnVision (SRS) will have a similar working frequency (subject to analysis). The RIME boom will preliminary act as the design case for the EnVision study. However, there are severe doubts that the current design will be appropriate to work in the Venus environment with the given constraints of the EnVision mission. The activity shall compare and analyse the different mission requirements and the deduced boom requirements with the existing design. Any non-compatibilities shall be addressed by animproved design solution. In a second phase the new design approach shall be built into a breadboard and tested under relevant conditions.
