Here, we study very low-altitude orbits (down to 50 km) in a high-degree and order model of the Martian gravity field. We apply Prony's Frequency Analysis (FA) to characterize the time variation of their orbital elements by computing accurate quasi-periodic decompositions of the eccentricity and inclination vectors. -
ESA Strategy for Science at the Moon
ESA UNCLASSIFIED - Releasable to the Public ESA Strategy for Science at the Moon ESA UNCLASSIFIED - Releasable to the Public EXECUTIVE SUMMARY A new era of space exploration is beginning, with multiple international and private sector actors engaged and with the Moon as its cornerstone. This renaissance in lunar exploration will offer new opportunities for science across a multitude of disciplines from planetary geology to astronomy and astrobiology whilst preparing the knowledge humanity will need to explore further into the Solar System. Recent missions and new analyses of samples retrieved during Apollo have transformed our understanding of the Moon and the science that can be performed there. We now understand the scientific importance of further exploration of the Moon to understand the origins and evolution of Earth and the cosmic context of life’s emergence on Earth and our future in space. ESA’s priorities for scientific activities at the Moon in the next ten years are: • Analysis of new and diverse samples from the Moon. • Detection and characterisation of polar water ice and other lunar volatiles. • Deployment of geophysical instruments and the build up a global geophysical network. • Identification and characterisation of potential resources for future exploration. • Deployment long wavelength radio astronomy receivers on the lunar far side. • Characterisation of the dynamic dust, charge and plasma environment. • Characterisation of biological sensitivity to the lunar environment.

Design of a Human Settlement on Mars Using In-Situ Resources
46th International Conference on Environmental Systems ICES-2016-151 10-14 July 2016, Vienna, Austria Design of a Human Settlement on Mars Using In-Situ Resources Marlies Arnhof1 Vienna University of Technology, Vienna, 1040, Austria Mars provides plenty of raw materials needed to establish a lasting, self-sufficient human colony on its surface. Due to the planet's vast distance from Earth, it is neither possible nor economically reasonable to provide permanent, interplanetary supply. In-situ resource utilization (ISRU) will be necessary to keep the Earth launch burden and mission costs as low as possible, and to provide – apart from propellant and life support – a variety of construction material. However, to include outposts on other planets into the scope of human spaceflight also opens up new psychological and sociological challenges. Crews will live in extreme environments under isolated and confined conditions for much longer periods of time than ever before. Therefore, the design of a Mars habitat requires most careful consideration of physiological as well as psychosocial conditions of living in space. In this design for a Martian settlement, the author proposes that – following preliminary automated exploration – a basic surface base brought from Earth would be set up. Bags of unprocessed Martian regolith would be used to provide additional shielding for the habitat. Once the viability of the base and its production facilities are secured, the settlement would be expanded, using planetary resources. Martian concrete – processed regolith with a polymeric binder – would be used as main in-situ construction material. To provide optimum living and working conditions, the base would respond to the environment and the residents' number and needs, thereby evolving and growing continuously. -
Long-Range Rovers for Mars Exploration and Sample Return
2001-01-2138 Long-Range Rovers for Mars Exploration and Sample Return Joe C. Parrish NASA Headquarters ABSTRACT This paper discusses long-range rovers to be flown as part of NASA’s newly reformulated Mars Exploration Program (MEP). These rovers are currently scheduled for launch first in 2007 as part of a joint science and technology mission, and then again in 2011 as part of a planned Mars Sample Return (MSR) mission. These rovers are characterized by substantially longer range capability than their predecessors in the 1997 Mars Pathfinder and 2003 Mars Exploration Rover (MER) missions. Topics addressed in this paper include the rover mission objectives, key design features, and Figure 1: Rover Size Comparison (Mars Pathfinder, Mars Exploration technologies. Rover, ’07 Smart Lander/Mobile Laboratory) INTRODUCTION NASA is leading a multinational program to explore above, below, and on the surface of Mars. A new The first of these rovers, the Smart Lander/Mobile architecture for the Mars Exploration Program has Laboratory (SLML) is scheduled for launch in 2007. The recently been announced [1], and it incorporates a current program baseline is to use this mission as a joint number of missions through the rest of this decade and science and technology mission that will contribute into the next. Among those missions are ambitious plans directly toward sample return missions planned for the to land rovers on the surface of Mars, with several turn of the decade. These sample return missions may purposes: (1) perform scientific explorations of the involve a rover of almost identical architecture to the surface; (2) demonstrate critical technologies for 2007 rover, except for the need to cache samples and collection, caching, and return of samples to Earth; (3) support their delivery into orbit for subsequent return to evaluate the suitability of the planet for potential manned Earth. -
