Enceladus is a prime scientific target due active geological features and evidence that liquid water might be present on this Saturnian moon. The surface of Enceladus is covered in active fissures known as “Tiger Stripes”. The plumes coming from these rifts were sampled by the Cassini mission, which detected carbon, hydrogen, oxygen, and nitrogen – all key signatures where life could exit. In order to access this moon, mission design using traditional fully-propulsive orbit insertion maneuvers is fuel expensive and time consuming, leading a prior study to rule traditional chemical and solar electric propulsion based missions infeasible. One alternative that enables this mission is Titan aerogravity assist, which is an aeroassist maneuver that combines atmospheric flight and gravity assist of Titan to allow a spacecraft to enter a planetary capture orbit about Saturn. This poster will look at the guidance and control techniques that are required to allow aerogravity assist to take place within Titan’s atmosphere.
