DESCRIPTION:Working toward genome-informed habitability of planetary enviro
 nments\n\nEarly Mars was likely habitable for life as we know it due in pa
 rt to the relative abundance of liquid water. For instance\, it is evidenc
 ed that Gale crater\, a late Noachian to early Hesperian-aged crater (3.5-
 3.8 Gya)\, contained a pH-neutral hyposaline lake. We have developed a sim
 ple community-based genome-scale model to evaluate the microbial habitabil
 ity of early Mars constrained by reconstructed water chemistry at Gale cra
 ter. Genome-scale models computationally describe microbial metabolisms ba
 sed on the specific genetic information encoded within said organisms. We 
 will first explore how genome-scale models are produced and then demonstra
 te how they can be used to predict biomass yields and the production of ot
 her metabolites (e.g.\, biomarkers) in the example of a Gale Lake environm
 ent. The results of that model illustrate the plausibility of a sustained 
 community in Gale Lake and establish a method that can be applied to other
  potentially habitable systems. Finally\, we will discuss in-progress impr
 ovements to genome-scale modeling\, in addition to current laboratory-base
 d collaborative efforts that will further evaluate the current habitabilit
 y of present-day Mars and Enceladus. \n\nAbout this Series: The MIT Planet
 ary Lunch Seminar [PLS] is a weekly seminar series organized within the EA
 PS department. Colloquia topics span the range of research interests of th
 e department's planetary sciences research program. The seminars take plac
 e on Tuesdays from 12:30–1:30 pm\, unless otherwise noted (term-time onl
 y). Speakers include members of the MIT community and visitors. Talks are 
 intended to appeal to graduate students\, postdocs\, research scientists\,
  and faculty with a background in planetary science. For more information
