Wikipedia:Articles for deletion/Modern Mars habitability
it is a notable topic with many papers published on it every year, as well two conferences or conference sessions: UCLA in 2013 and NASA / LPL in 2018. The citations used are similar to those used in other Wikipedia articles in the topic area - NASA online astrobiology magazine, mainstream astrobiology journals, with preference for review papers where available, NASA press releases and so on. Much of the material  in the first half is based on Nilton Renno's review paper in Space Science Reviews https://link.springer.com/article/10.1007%2Fs11214-012-9956-3/fulltext.html "Water and Brines on Mars: Current Evidence and Implications for MSL" and on the sources cited by him. The POV's are as expressed in the sources. There's also a section Modern Mars habitability#Views on the possibility of present day life on or near the surface which gives an idea of the range of views on this matter as in the sources given. If any particular sources are questionable or any POV's inaccurately summarized please elaborate on the talk page of the article. On the length then it's not a problem for those not interested in the topic or who find the section in Life on Mars#Habitability sufficent for them, by . And for those that need to find out more, the thoroughness of it is valuable - I have covered all the most significant findings of the last decade in this topic area succintly. On tone, then that is easily fixed by wikignoming / copy editing if you see issues of that sort. It has been in Wikipedia now since March 2017. I am baffled that it suddenly has an AfD without prior talk page discussion
