Nature: Closing in on Jupiter's Past
Aviation Week and Space Technology: NASA bets big rover on novel landing scheme
I also discovered a new blog that covers space exploration, including in-depth posts on planetary exploration. I'm not sure how I missed this blog for so long; perhaps because it's in Spanish and my search terms didn't translate well. (Google translate seems to do a pretty good job at providing readable English text.) I've added this blog to my blog list, and you can visit it at http://danielmarin.blogspot.com/.
