Hyderabad, Sep 25 (UNI) Visualising all the requirements for design, assembly and operation of human habitation bases on Moon and Mars was a very difficult task, an ISRO scientist said today.

Presenting a paper on 'Strategic technological and ethical aspects of establishing colonies on moon and Mars' on behalf of Indian Space Resarch Organisation (ISRO) Chairman Madhavan Nair at the 58th International Astronautical Congress (IAF 2007) here, ISRO Director (Ahmedabad ) Dr MYS Prasad said ''It is more complex for a habitat on Mars than on the Moon. The life support system on Moon and Mars should be based on the life support system of present space stations in Earth's orbit, at least for the initial period.'' Present research on effects of long duration flights in weightlessness and adaptation to low gravity conditions on Mars were not sufficient to meet the challenges of Mars habitats, he said, adding the experience of astronauts in future on moon bases would become essential to tackle this fundamental issue for planning Mars bases.

Stating that the strategic aspects for establishing human habitation bases on both moon and Mars related to a large space exploration plan, essentially to deal with the cost and time schedule of realisation, Mr Prasad said ''We should aim at optimising the resources and the time schedule through international cooperative ventures''.

''The ethical aspect also raises a few questions mainly dealing with issues like avoiding harmful contamination of these celestial bodies. The exploitation of in-situ resources of moon and Mars for the benefit of the whole of humankind should be the goal of all countries and space agencies planning for such activities in future,'' he added.
