The Countdown: 5/27/2010


3… ESA approved moving forward with a joint ESA/NASA Mars exploration program. This takes us one step closer to the 2016 ExoMars Trace Gas Orbiter… and to a 2018 Mars Sample Return caching mission.

2… Two words: olivine rain.

1… Today, Science published the final version of the Wolfe-Simon et al. “Arsenic-using bacteria paper,” as well as the eight technical comments on the paper, and the reply to those comments by Wolfe-Simon et al. Needless to say, we’ll be covering this. This will be the subject of our first “journal club” conversation, next week. Join us then to discuss the debate in the paper/comments/reply, and potential research that could be pursued to validate or refute the claims therein. In the meantime, we will host some “meta” conversations about high-profile/high-impact research, with this as a “case study.” Stay tuned for more…
