The AERODEM is an ESA demonstration mission that will implement an aerocapture phase in order to provide an atmospheric ∆V instead of a standard chemical one for orbiting a SpaceCraft around Mars. The aerocapture technique currently studied relies on a discrete event drag modulation technique that modifies only once the aerocapture module ballistic coefficient by separating / retracting the heatshield.

An interplanetary probe must decelerate from a hyperbolic interplanetory trajectory to an orbital trajectory when it arrives at its destination. Currently, this maneuvre is achieved using chemical propulsion, which means that propellant makes up a significant fraction of the vehicle mass. Aerocapture is an alternative concept that instead uses aerodynamic drag from the athmosphere of the planet to decelerate the arriving spacecraft.

In the frame of an In Orbit Servicing Maturation Phase (IOSMP) contract, this maturation study has been realised on the START-€ solution which is proposed to extend the lifetime of geostationary orbit (GEO) communication satellites. The START-€ servicer spacecraft will first demonstrate on a GEO communication satellite its ability to perform the critical operations related to its mission, before proceeding with several commercial life extension missions by capturing and taking the AOCS control of aged client spacecraft.

The results of the IOSPR maturation phase study done by D-Orbit (UK) are presented.

This work has primarily focused on establishing scenarios where inflatable devices could be the most useful. Given that these missions rely on aerodynamic drag that results in (potentially significant) heating, the authors have sought to find solutions to minimize heat fluxes acting on the device surface, and especially keeping it within the limits of flexible/foldable TPS materials for the aerocapture scenario.

The study demonstrates that in an emergency situation, with only a very short warning time, the launch of a fast asteroid kinetic deflection mission is feasible (targeting launch-readiness in six months!), given that certain identified pre-requisites have been prepared well in advance. The capabilities and requirements of 'hijacking' and modifying a commercial spacecraft platform in order to perform asteroid kinetic deflection in the shortest possible time were consequently assessed.

Resulting from an ever increasing public pressure, the quest to be environmentally friendly is transforming the competitive landscape, as eco-friendly design results in a new frontier of innovation. As a public sector intergovernmental organisation, ESA is committed to prioritising environmental concerns in all its activities. Through its Clean Space initiative, the Agency is pioneering an eco-friendly approach to space activities.
