“…After finishing the balloon phase the orbiter will be put in a circular orbit around Venus, which will be achieved by aerobraking in the upper atmosphere of Venus as mentioned before. This technique has been successfully demonstrated by Venus Express [79]. The final orbit will have an altitude of 250 km with an inclination of 85 • .…”

The Hesperos mission proposed in this paper is a mission to Venus to investigate the interior structure and the current level of activity. The main questions to be answered with this mission are whether Venus has an internal structure and composition similar to Earth and if Venus is still tectonically active. To do so the mission will consist of two elements: an orbiter to investigate the interior and changes over longer periods of time and a balloon floating at an altitude between 40 and 60 km to investigate the composition of the atmosphere. The mission will start with the deployment of the balloon which will operate for about 25 days. During this time the orbiter acts as a

Mars orbit insertion via ballistic capture and aerobraking

A novel Mars orbit insertion strategy that combines ballistic capture and aerobraking is presented. Mars ballistic capture orbits that neglect aerodynamics are first generated, which are distilled from properly computed stable and unstable sets by using an already-established method. A small periapsis maneuver is implemented at first close encounter to better submit the post-capture orbit to the aerobraking process. An ad-hoc patching point marks the transition from ballistic capture to aerobraking, from which an exponential model simulating Mars atmosphere and a box-wing satellite configuration is considered. A series of apoapsis trim maneuvers are then computed by targeting a prescribed pericenter dynamic pressure. The aerobraking duration is estimated by using a simplified two-body model. A yaw angle tuning cancels inclination deflections due to out-of-plane perturbation from the Sun. A philosophy combining in-plane and out-of-plane dynamics is proposed to achieve the required semi-major axis and inclination simultaneously. Numerical simulations indicate that the developed method is more efficient in terms of fuel consumption, insertion safety, and flexibility than state-of-the-art insertion strategies.
