http://www.wired.com/2013/10/mars-polar-ice-sample-return-1977-1978/ I found this old Wired article interesting. It makes me wonder, with all the cash that is thrown at Mars exploration these days, why an updated version of this has not been attempted? It would seem that analysis of a Martian ice core sample could yield some answers concerning past climate or even possible ancient microbial life. Ice cores have been good sources for information on Earth, so they should offer a fairly useful record of Mars' distant past. Given that technology is more advanced today than it was in 1978, the analysis might even be possible right there on Mars without the need for a return mission. Analyzing the core on Mars would certainly limit the possibility of contaminants from Earth. Why is it that the idea of studying Martian ice cores has seemingly been abandoned?
