Dynamic interactions in a space mission and challenges of aerothermodynamics of Mars atmospheric entry

  • V Adimurthy


There is a substantial scientific interest on Mars because it is the most earth-like planet in our solar system. The Mars Orbiter Mission of Indian Space Research Organisation took off with a precise Earth-Orbital launch on 5th November 2013 handling all the complex nonlinear interactions of the launch systems. Subsequent successful orbit raising operations and insertion of the spacecraft into Mars Transfer Trajectory augur a journey to Mars Orbit of a great significance. In this broad survey paper we address the complex dynamic interactions of a space launch and the future challenges of aerothermodynamics of Mars atmospheric entry, descent and landing. While a number of complex orbiter and rover missions to Mars have already taken place, the past missions cannot be scaled to larger masses. The paper highlights the current technological limitations in this context, with particular
reference to the intrinsic topography and the relatively highly rarefied atmosphere around Mars. The aerothermodynamics challenges and solutions to Mars Entry, Descent and Landing are unique and require development of new technological solutions. The current trends in the development of
these technologies and the future directions are highlighted.
