Swarm exploration and navigation on mars
2013 International Conference on Localization and GNSS (ICL-GNSS), 2013We propose autonomous robotic swarm exploration to search for extra-terrestrial life in the Valles Marineris canyon system on Mars. The swarm consists of unmanned ground vehicles (UGVs) and unmanned aerial vehicles (UAVs). Key technologies are robust flight and swarm control algorithms as well as infrastructure-less swarm navigation.

Low-Thrust-Enabled Highly-Non-Keplerian Orbits in Support of Future Mars Exploration [PDF]
Journal of Guidance, Control, and Dynamics, 2011 The technology of high specific impulse propulsion systems with low thrust is improving, opening up numerous possibilities for future missions applying continuous thrust to force a spacecraft out of a natural Keplerian orbit into a displaced non ...

Exobiology and the Exploration of Mars
Applied Optics, 1969Our limited understanding of the Martian environment has stimulated much speculation on the possible existence of a. Martin biota. This understanding is being steadily improved by ground-based observing techniques. Rapid advances have been made by the Mariner IV flyby and will be made by the Mariner 1969 flybys and the Mariner 1971 orbiters.

The Mars exploration plans of ESA
IEEE Robotics & Automation Magazine, 2006In the framework of its Aurora Exploration Program, the European Space Agency (ESA) has initiated the ExoMars Project. Aside from searching for traces of life at and near the Martian surface, ExoMars aims to characterize the Martian geochemistry and water distribution at various locations, improve the knowledge of the Mars environment and geophysics ...

Mars exploration advances: Missions to Mars - Mars base
30th Aerospace Sciences Meeting and Exhibit, 1992An overview is presented of Mars missions and related planning with attention given to four mission architectures in the light of significant limitations. Planned unpiloted missions are discussed including the Mars Orbital Mapping Mission, the Mars Rover Sample Return, the Mars Aeronomy Orbiter, and the Mars Environmental Survey.

Mathematics and Mars Exploration
Pure and Applied Geophysics, 2014In this study we consider modelization associated with study of solar radiation at the surface of Mars and the Martian atmosphere. In particular, we present elements concerning retrieval of the solar irradiance spectrum on the surface of Mars from data collected by arrays of photodiodes, such as those onboard the “Curiosity” MSL-rover and other ...

31st Aerospace Sciences Meeting, 1993
Mars exploration planning is discussed which is based on three scientific objectives: to understand Mars' geologic and geophysical evolution; to understand the present state and past evolution of Martian climate, and to determine the state of present biological activity and past life.

Relay communications for Mars exploration
International Journal of Satellite Communications and Networking, 2007AbstractTelecommunication is an essential and challenging aspect of planetary exploration. For Mars landers, the constraints of mass, volume, power and energy typically limit their communications capabilities on the long‐distance link back to Earth. By deploying relay spacecraft in Martian orbit, these landers can achieve much greater data return and ...

Proceedings of the 29th International Conference on Computer Graphics and Interactive Techniques. Electronic Art and Animation Catalog., 2002
This 100-percent CG visualization shows the Delta II rocket launch that will propel NASA's Mars Exploration Rover to the Red Planet in 2003. The animation, developed over a one-year period by a Cornell University undergraduate student, is intended to be dramatic, realistic, and scientifically accurate. It was created with a combination of off-the-shelf
