TL;DR: The Mars 2020 mission will seek the signs of ancient life on Mars and will identify, prepare, document, and cache a set of samples for possible return to Earth by a follow-on mission as discussed by the authors.

TL;DR: The iMOST team as mentioned in this paper defined a set of science and engineering objectives for the Mars Sample Return (MSR) campaign and provided a framework for demonstrating how the first set of returned Martian samples would impact future Martian science and exploration.

TL;DR: The abdomen of the fossil mosquito was shown to contain very high levels of iron, and mass spectrometry data provided a convincing identification of porphyrin molecules derived from the oxygen-carrying heme moiety of hemoglobin, which confirm the existence of taphonomic conditions conducive to the preservation of biomolecules through deep time and support previous reports of theexistence of heme-derived porphyrs in terrestrial fossils.

TL;DR: The photogeologic map presented here is the foundation for scientific hypothesis development and strategic planning for Perseverance's exploration of Jezero crater and considers four possible unit correlations to explain the relative age relationships of major units within the map area.

TL;DR: It is discovered that these extinct lacewings convergently evolved wing eyespots that possibly contained melanin, and wing scales, elongate tubular proboscides, similar feeding styles, and seed–plant associations, similar to butterflies, found in these two, unrelated clades.
