Taking the Temperature of Ancient Mars

A meteorite blasted off the surface of Mars, ALH 84001, was found to have fossilized microbes in it. Until recently it was unknown the fossils were caused by actual life or just heat and various weather impacts. Because of a new theory developed by John Eiler, however, it has been implied that the formation temperature of ALH 84001 is only 18 degrees celsius. Given this temperature, ancient Mars may have had a cooler climate than originally suspected.

Wow! I guess that means we have found evidence of ancient extraterrestrial life. What a discovery.

The research states that ancient mars was 18 degrees;it was not too cold or too hot. That temperature suggests that there was the potential of life on mars! I wonder what astronomers will discover when they find ALH 84001's launch site.

I wonder when they will discover whether or not the fossils are significant evidence for life

I like how this relates to our current unit, learning about the planets. This gives us more insight on ancient Mars and could possibly help in determining if there was life on Mars
