 Write a Review of NASA Astrobiology Magazine Podcast
  
personalmedia, February 17, 2006
Reviewer: personalmedia
from Indiana
The first daily podcast I reviewed was presented by an odd monotone female voice that sounded computer-generated. The content of the podcast relating to life on Mars was interesting, but the poor sound quality of the podcast was very distracting from the information presented.
The second NASA Astrobiology Magazine Podcast I reviewed was on the topic of establishing human bases on the moon. Again, the content of the podcast was intriguing, but the male voice presenting the information was broken up and monotone. Individuals who are fascinated with astronomy will probably find these podcasts worth listening to. The sound quality definitely needs improvement. It detracts from the excellent content of these podcasts.

Life on Mars Gets Cold Shoulder
Friday, July 22, 2005
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.

Proving the Case
Thursday, August 04, 2005
On Earth, methane is mostly produced by life. The recent detection of methane on Mars therefore has led to much speculation about the possibility for life on the Red Planet. The strategies that may resolve this issue are revealed in the final part of this series on martian methane.

Mystery Methane Maker
Friday, August 05, 2005
The detections of methane in the martian atmosphere have challenged scientists to find a source for the gas, which is usually associated with life on Earth. One source that can be ruled out is ancient history: Methane can survive only 600 years in the martian atmosphere before sunlight will destroy it.

Snowball Earth
Sunday, August 07, 2005
For several years geologists have been gathering evidence indicating that Earth has gone into a deep freeze on several occasions, with ice covering even the equator and with potentially devastating consequences for life. The theory, known as "Snowball Earth," has been lacking a good explanation for what triggered the global glaciations.
