Abstract
In situ measurements by an atmospheric entry probe allow for sounding and investigating atmospheric composition, structure and dynamics deep into the atmosphere of a Giant planet. In this paper, we describe an Atmospheric Structure Instrument (ASI) for an entry probe at Uranus and/or Neptune. The scientific objectives, the measurements and the expected results are discussed in the framework of a future opportunity for an NASA-ESA joint mission to the Ice Giant planets.
Notes
An Electric field mill is an instrument to measure the strength of the electric fields in the atmosphere by means of a rotating shutter or chopped wheel (the “mill”) exposing or shielding electrodes. The electric current, which flows to and from the electrodes, is proportional to the strength of the electric field. This type of instrument can be deployed airborne and flown through anvil head clouds; by monitoring the atmospheric electric fields can be used for lightning protection (e.g. in rocket launch support or outdoor laboratories).
Exosphere is the upper most layer of the atmosphere merging with interplanetary space, where molecules are gravitationally bound to the body. The lower boundary of the exosphere is called the exobase or exopause, and this is the altitude where barometric conditions no longer apply.
