Abstract Sulfur plays a major role in martian geochemistry and sulfate minerals are important repositories of water. However, their hydration states on Mars poorly constrained. Therefore, understanding the distribution is for its geologic, hydrologic, atmospheric evolution as well habitability potential. NASA's Perseverance rover currently exploring Noachian‐age Jezero crater, which hosts fan‐delta system associated with paleolake. The crater floor includes two igneous units (the Séítah Máaz...
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...
In vitro transcriptions of the 98‐nucleotide intron found in Chlorella virus pdg locus always produce at least one slower‐migrating species (as ~10–20% total transcription yield) addition to expected transcripts. Extensive characterization these products suggests that they are knotted RNA molecules, which we call knRNAs , previously observed only by ligation synthetic ribo‐oligonucleotides. An with knot‐forming interactions would display physical properties unique this topology. The...
