The growing number of missions has brought previously unapproachable and incomprehensible regions of the universe into the realm of our understanding. The millennial boosts in technological innovations have enabled us to expand the horizons of our exploration far beyond our immediate neighborhood in the solar system. As is inevitable for any scientific discovery of magnitude, to open up questions for further evaluations, recent space endeavors have necessitated the search for analogue sites on Earth that mimic these extraterrestrial sites in order to glean insights into physicochemical and geological processes, potential habitability and operational parameters for future missions[1]. Various analogue sites have been identified across the world on the basis of their resemblance to a celestial body of interest. These sites have been used to address questions pertaining to distinct fields of inquiry, i.e., the origin and evolution of life, habitability and biosignatures, in addition to the ground testing of several instruments to be used at these off-Earth locations. This study explores the role of one such analogue site, Ladakh. Ladakh is located in the Himalayan region, situated North of the Indian subcontinent. Located at elevations of 3,000-5,700m above sea level, its geographical location means that this region has been exposed to limited natural weathering and anthropogenic activities, as it is in the rain-shadow region and it is difficult to access. Furthermore, the high altitude nature of this region means that there is the challenge of the stressful conditions of cold temperatures, low oxygen partial pressure and high UV irradiation. Though testing in terms of survival, these geophysical features result in Ladakh being considered a suitable Mars analogue, sharing a low atmospheric pressure and a high UV index given the lack of magnetic activity and sparseness of its atmosphere. Scouted as part of the first NASA Spaceward Bound India (SBI) program of 2016, Ladakh offers the unique advantage of being an amalgamation of multiple extreme environments with astrobiological significance within the same region. The cold arid desert conditions of Ladakh harbor varied geological features and features of scientific interest, including glacial deposits, hot springs, sand dunes, salt crusts, permafrost regions, and saline lakes [2]. Each of these sites are characterized by distinct geological features that can help provide answers to fundamental questions pertaining to habitability (extremophilic microbes residing in hot springs with temperatures of 70°C to those surviving under permafrost conditions where the temperatures never rise above 0°C) and potential biosignatures that could be formed and preserved under conditions considered analogous to environments on Mars. The biogeochemical features, like the ionic composition and temperatures of hot springs environments, could be used to drive research towards the origin and subsequent evolution and diversification of the earliest life forms [3]. Moreover, the rugged terrain of Ladakh provides perfect grounds for the testing of rover and landing mission instruments, like the HABIT (HabitAbility, Brine Irradiation and Temperature), an instrument tested during the SBI 2016 expedition, which is used for evaluating the habitability and also explore the In-Situ Resource Utilization (ISRU) options for ExoMars mission [4]. Its field trial in Ladakh aimed at establishing its basic functional principle of capturing water on salt surfaces to create a brine, which may be relevant for future missions. With strong potential to act as an analogue site for Mars, Ladakh remains an enigma to be explored. [ABSTRACT FROM AUTHOR]
