Confirmation Of An Ancient Lake On Mars Builds Excitement For Perseverance Rover’s Samples

by Keith CowingJanuary 27, 2024January 27, 2024

If life ever existed on Mars, the Perseverance rover’s verification of lake sediments at the base of the Jezero crater reinforces the hope that traces might be found in the […]

Bioenergetic results from the modeled simulations showing the feasibility of sulfate reduction, methanotrophy, methanogenesis, and anaerobic methane oxidation (AMO), based on Gibbs Energy quantification. All reactions at equilibrium are exergonic at all modeled conditions. Computed Gibbs Free Energy of Reaction is displayed as kJ/mol per e− transferred in the given reaction. -- Life

Mineral Indicators of Geologically Recent Past Habitability on Mars

by Keith CowingJanuary 3, 2024January 3, 2024

We provide new support for habitable microenvironments in the near-subsurface of Mars, hosted in Fe- and Mg-rich rock units, and present a list of minerals that can serve as indicators […]

This animated artist’s concept depicts a scene of water breaking through the rim of Mars’ Jezero Crater, which NASA’s Perseverance rover is now exploring. Water entered the crater billions of years ago, depositing sediments that built up into a delta. -- NASA

Video: Water Enters Jezero Crater Billions of Years Ago (Artist’s Concept)

by Keith CowingDecember 15, 2023December 15, 2023

Since the spacecraft’s landing in February 2021, Perseverance’s exploration of the crater floor and the delta have led to scientists developing a detailed timeline for the crater’s formation. They now […]

This 360-degree mosaic from the “Airey Hill” location inside Jezero Crater was generated using 993 individual images taken by the Perseverance Mars rover’s Mastcam-Z from Nov. 3-6. The rover remained parked at Airey Hill for several weeks during solar conjunction. Credit: NASA/JPL-Caltech/ASU/MSSS

Perseverance Deciphers The Ancient History Of A Martian Lake

by Keith CowingDecember 12, 2023December 12, 2023

Marking its 1,000th Martian day on the Red Planet, NASA’s Perseverance rover recently completed its exploration of the ancient river delta that holds evidence of a lake that filled Jezero […]

Illustrations of magnetotactic bacteria (MTB) under electron microscopes, and MTB from extreme environments on Earth and putatively ancient Mars. A The scanning electron micrograph and (B, C) transmission electron micrographs of MTB. White arrows indicate magnetosome chains, and white triangles indicate granules. D Terrestrial extremotolerant MTB and implications for ancient Mars. MTB are found to be able to resist various hostile settings, such as irradiation, hypomagnetic exposure, microgravity, metal stress, hypersalinity, acidic/hyperalkaline pH, and freezing/moderately hyperthermal temperatures. MTB emerged early in Earth’s history. Since ancient Mars was also characterized by many MTB-favorable aquatic/sediment oxic-anoxic conditions and a global magnetic field, it is proposed that Mars may have harbored MTB-like life in the past. -- ISME

New Perseverance Rover Research Provides More Signs Of Possible Organic Molecules On Mars

by Keith CowingJuly 19, 2023July 19, 2023

Little green men it isn’t — but a new study co-led by a Pitt PhD candidate shows the potential for a variety of carbon-based molecules in a crater on Mars. […]

The Mastcam-Z imager on NASA’s Perseverance rover captured a series of images on July 6 that were stitched together to show a field of boulders deposited in Jezero Crater by a fast-moving ancient river. Rover tracks across the middle of the image give a sense of scale. Credit: NASA/JPL-Caltech/ASU/MSSS

An Ancient Riverbed On Mars Is Helping Perseverance Do Its Work

by Keith CowingJuly 19, 2023July 19, 2023

The six-wheeled geologist is getting some assistance in its search for diverse rock samples that could be brought to Earth for deeper investigation.

a, High Resolution Imaging ScienceExperiment (HiRISE) image of the region studied with the rover’s traverse marked in white, the boundary between the Séítah and Máaz fm delineated by the light blue line, and each rock target labelled. Scale bar, 100 m. b, Average number of fluorescence detections (out of 1,296 points) from survey scans for each target interrogated by SHERLOC, arranged in order of observation. *The acquisition conditions were different for dust-covered natural targets as compared to relatively dust-free abraded targets, possibly resulting in reduced detections. c, WATSON images of natural (red box) and abraded targets (Máaz is the blue box, Séítah is the green box) analysed in this study, with SHERLOC survey scan footprints outlined in white. Two survey scans were performed on Guillaumes, Dourbes and Quartier. Sol 141 imaging on Foux had an incomplete overlap of WATSON imaging and SHERLOC spectroscopy mapping. Scale bars, 5 mm. -- Nature
