- Abstract
The goal of the paper is to describe the ESA activities concerning the analysis of guidance trajectories for vehicles with entries in Mars. The article describes different vehicles for different missions within the ESA preparatory Exploration program. The article starts with an introduction about ESA activities on trajectory guidance systems that have been performed on support to the ESA Exploration program. The addressed missions range from the delivery of a rover around 2009 until the delivery of a crew in 2030. The paper continues with a description of the ESA tools and techniques on the design of the trajectory subsystems for the different entry probes, and the scenarios used. The paper describes a on detail a full mission scenario of the ExoMars mission to arrive in Mars in 2009. Its goal is to deliver a rover with the Pasteur exobiology experiments payload on it. The paper also discusses important issues of entry using parachute versus entry using inflatable breaking devices. Advantages and disadvantages of either system is discussed and analyzed in detail. The paper addresses also the analysis of the guidance stabilization issues of entry probes in Mars. The problem of the 6DoF stabilization is shown in depth with a big number of simulation runs. The paper further explains that the optimal guidance is calculated by the ESA optimal trajectory finder ASTOS, while the navigation and control parts are simulated using code written in MATLAB.
