		<description><![CDATA[Astrobiology Magazine presents a new podcast with our host Simon Mitton. In this interview, Beda Hofmann, an astrobiologist at the Natural History Museum in Bern, Switzerland, explores the links between meteorites, asteroids, and astrobiology. Europe's proposed Marco Polo Mission would land on an asteroid, drill down for samples, and return them to Earth. As Hofmann explains, the samples will be older than any rocks on Earth, and may contain important clues on the formation of the solar system.]]></description>

		<description><![CDATA[Host Simon Mitton interviews Axel Brandenburg, an astrobiologist at the NORDITA research facility at Stockholm in Sweden. In this interview, Brandenburg considers why terrestrial life is based on molecules that have a left-handed symmetry, when their mirror images should work just as well. He considers the intriguing question: could life be right handed, at the molecular level, elsewhere in the solar system?]]></description>

In this interview, Tim Livengood of the Universities Space Research Association and Vikki Meadows of the University of Washington in Seattle describe how the EPOXI mission developed from NASA's Deep Impact mission. The Deep Impact spacecraft, having successfully delivered an impact probe to the comet Tempel 1, now will be used to search for Earth-like planets orbiting distant stars. The spacecraft also has been used to observe Earth from a distance, helping scientists understand how gases in the atmosphere can indicate whether distant worlds contain life.]]></description>

		<description><![CDATA[Astrobiology Magazine presents its latest podcast with our host Simon Mitton. In this interview, Brian Jackson, a NASA Earth and Space Sciences Fellow in the Department of Planetary Sciences at the University of Arizona, explores the importance of tidal heating in determining the habitability of planets. Tidal heating, which is generated by orbiting a massive gravitational body like a star or giant planet, can heat up a planet or moon. If there is too much tidal heating, though, the resulting volcanism can create torrid conditions unsuitable for life.]]></description>

		<description><![CDATA[In the July 22 issue of the journal Science, Caltech graduate student David Shuster and MIT assistant professor Benjamin Weiss (formerly a Caltech student) report that their studies of Martian meteorites demonstrate that at least several rocks originally located near the surface of Mars have been freezing cold for four billion years. Their work is a novel approach to extracting information on the past climate of Mars through the study of Martian meteorites. In fact, the evidence shows that during the last four billion years, Mars has likely never been sufficiently warm for liquid water to have flowed on the surface for extended periods of time. This implies that Mars has probably never had a hospitable environment for life to have evolved, unless life could have gotten started during the first half-billion years of its existence, when the planet was probably warmer.]]></description>
