66511 Comparative Planetology

Planet earth, the solar system, and the existence of other earth-like planets in the universe are the topics covered in this subject. This is a learner-centred elective, in which students determine the level of depth to which they wish to pursue the topics. Concepts covered in this subject are: origin and composition of the solar nebula; formation of the solar system; planetesimals, meteorites and comets; formation of terrestrial and Jovian planets and their satellites; composition of the planets; magmatic and tectonic evolution of the terrestrial planets; significance of early magmatism with regard to the origin of life on planet earth; earth's crustal processes and their impact on global climate patterns; possibility and probability of existence of planetary systems similar to the solar system in the rest of the galaxy; and possibility and probability that conditions similar to those of early earth, leading to the formation of the biosphere, may have existed elsewhere in the galaxy.

There are two specific subsections to the subject. One focuses on catastrophic events caused by planetesimal impacts (mass extinctions during earth's history). And the other on the red planet (Mars) and issues related to its exploration. These subsections form the core of specifically designed tutorials to be explored and led by groups of students.

In addition to tutorials, the subject is formally delivered as a series of lectures; a few seminars delivered by invited speakers, chosen among recognised leaders in their fields (dependent on speakers' availability); and numerical problems and practicals as appropriate to each topic; day excursions may also be included. Grades are dependent on the level of depth and accuracy aimed for and achieved by the individual students in their approach to the topics covered.

This is an advanced-level subject that will appeal to students in science majors and those in other disciplines. It is available to students in any UTS degree; non-award and cross-institutional students are encouraged to enrol.

The subject is only offered twice every three years. It is offered in 2006.
