The Perseverance rover landed in Jezero crater, Mars, February 2021. We used the Scanning Habitable Environments with Raman and Luminescence for Organics Chemicals (SHERLOC) instrument to perform deep-ultraviolet fluorescence spectroscopy of three rocks within crater. identify evidence two distinct ancient aqueous environments at different times. Reactions liquid water formed carbonates an olivine-rich igneous rock. A sulfate-perchlorate mixture is present rocks, which probably by later...
Abstract The presence and distribution of preserved organic matter on the surface Mars can provide key information about Martian carbon cycle potential planet to host life throughout its history. Several types molecules have been previously detected in meteorites 1 at Gale crater, 2–4 . Evaluating diversity detectability elsewhere is important for understanding extent processes availability sources 1,5,6 Here we report detection Raman fluorescence spectra consistent with several species...
Abstract The goals of NASA's Mars 2020 mission include searching for evidence ancient life on Mars, studying the geology Jezero crater, understanding Mars' current and past climate, preparing human exploration Mars. During mission's first science campaign, Perseverance rover's SHERLOC deep UV Raman fluorescence instrument collected microscale, two‐dimensional images 10 natural (unabraded) abraded targets two different crater floor units: Séítah Máaz. We report measurements during Crater...
The Mars 2020 mission will analyze samples in situ and identify any that could have preserved biosignatures ancient habitable environments for later return to Earth. Highest priority targeted include aqueously formed sedimentary lithologies. On Earth, such lithologies can contain fossil as aromatic carbon (kerogen). In this study, we analyzed nonextracted kerogen a diverse suite of natural, complex using colocated UV excitation (266 nm) time-gated (UV-TG) Raman laser-induced fluorescence...
We present a synthesis of PIXL elemental data and SHERLOC Raman spectra collected on two targets investigated by the Perseverance rover during first year its exploration Jezero Crater, Mars. The Bellegarde target (in Máaz formation) Dourbes Séítah exhibit distinctive mineralogies that are an ideal case study for in situ analysis PIXL. Each instrument alone produces valuable about chemistry spatial distribution mineral phases at sub-millimeter scale. However, combining from both instruments...
The NASA Mars 2020 Perseverance rover is currently exploring Jezero crater, a Noachian-Hesperian locality that once hosted delta-lake system with high habitability and biosignature preservation potential. conducts detailed appraisals of rock targets using synergistic payload capable geological characterization from kilometer to micron scales. highest-resolution textural chemical information will be provided by correlated WATSON (imaging), SHERLOC (deep-UV Raman fluorescence spectroscopy),...
Assessing biosignature preservation potential (BPP) in ancient habitable environments on Mars is a top NASA priority. We address this goal through the study of Miocene-Pliocene evaporites Verde Formation (central Arizona). assessed effects diagenesis BPP, integrating outcrop-scale observations with six lab analyses: thin-section petrography, X-ray diffraction, Raman spectroscopy, total organic carbon (TOC), electron probe microanalysis (EPMA), and visible to near-infrared (VNIR) reflectance...
The Mars 2020 Perseverance rover landed on February 18, 2021, and has started ground operations. ExoMars Rosalind Franklin will touch down June 10, 2023. be the first-ever sample caching mission-a first step in return to Earth. SuperCam Scanning Habitable Environments with Raman & Luminescence for Organics Chemicals (SHERLOC) Perseverance, Laser Spectrometer (RLS) Franklin, comprise ever situ planetary mission spectroscopy instruments identify rocks, minerals, potential organic biosignatures...

Martian subsurface habitability and astrobiology
This work utilizes Improved Solar Observing Optical Network (ISOON: Neidig et al. 2003) continuum (630.2 nm) and H{\alpha} (656.2 data to: 1) detect measure intrinsic sunspot rotations occurring in the photosphere chromosphere, 2) identify chromospheric filament mass motions, 3) assess any large-scale photospheric couplings. Significant results from October 27-29, 2003, using techniques of Brown (2003), indicate significant counter-rotation between two large sunspots NOAA AR 10486 on 29, as...
The NASA Mars 2020 Perseverance rover mission will collect a suite of scientifically compelling samples for return to Earth. On the basis orbital data, science team* identified two notional sample caches study (1) geology Jezero crater, collected during prime and (2) ancient crust outside possible extended mission. crater consists well-preserved, Early Hesperian Late Noachian deltaic lacustrine deposits sourced from river system that drained terrain. floor comprises at least distinct units...
Martian subsurface habitability and astrobiology can be evaluated via a lava tube cave, without drilling. MACIE addresses two key goals of the Decadal Survey (2013-2022) three MEPAG goals. New advances in robotic architectures, autonomous navigation, target sample selection, analysis will enable to explore subsurface.
It may sound like something out of a science fiction novel, but both NASA and private space companies are seriously discussing long-term off-world habitation. Under the current 'Vision for Space Exploration', plans to return astronauts Moon then move on next challenge: Mars. 4Frontiers is new company preparing this challenge, developing strategies technologies be used in creating permanent human presence red planet. While humans not set foot Mars at least another decade, informative...

The author examines the end-user effect on NASA's pioneering technologies. Conducting myriad of space launch preparations requires innovative Although mission Applied Physics Laboratory at Kennedy Space Center is to deliver gadgets support these missions and operations, it verdict end-users (i.e. individuals or companies who use NASA product for more mundane purposes after has been developed) that dictates which ones are accepted.
