Spectral evidence for hydrated salts in recurring slope lineae on Mars
Lujendra Ojha,Mary Beth Wilhelm,Mary Beth Wilhelm,Scott L. Murchie,Alfred S. McEwen,James J. Wray,Jennifer Hanley,Marion Massé,Matthew Chojnacki +8 more
TL;DR: In this article, spectral analysis of spectral data reveals hydrated salts associated with the streaks, confirming a briny origin, but evidence of water or salts has been lacking, which is not the case in this paper.

Detection of Perchlorate and the Soluble Chemistry of Martian Soil at the Phoenix Lander Site
Michael H. Hecht,Samuel P. Kounaves,Richard C. Quinn,S. J. West,S. M. M. Young,Douglas W. Ming,David C. Catling,David C. Catling,B. C. Clark,William V. Boynton,John H. Hoffman,Lauren DeFlores,K. Gospodinova,J. Kapit,Peter H. Smith +14 more
TL;DR: Results suggest that the soil at the Phoenix landing site must have suffered alteration through the action of liquid water in geologically the recent past, and revealed an alkaline environment in contrast to that found by the Mars Exploration Rovers, indicating that many different environments have existed on Mars.
