TL;DR: A comprehensive analysis of some of these fragments shows that the Sutter's Mill meteorite represents a new type of carbonaceous chondrite, a rare and primitive class of meteorites that contain clues to the origin and evolution of primitive materials in the solar system.

TL;DR: The Stardust Interstellar Dust Collector captured seven particles and returned to Earth for laboratory analysis have features consistent with an origin in the contemporary interstellar dust stream and more than 50 spacecraft debris particles were also identified as discussed by the authors.

TL;DR: The Low-Energy Telescope (LET) is one of four sensors that make up the solar Energetic Particle (SEP) instrument of the IMPACT investigation for NASA's STEREO mission and is designed to measure the elemental composition, energy spectra, angular distributions, and arrival times of H to Ni ions over the energy range from ∼3 to ∼30 MeV/nucleon as discussed by the authors.

TL;DR: In this article, the authors reported on the mineralogy, petrography, and in situ measured oxygen and magnesium-isotope compositions of eight porphyritic chondrules (seven FeO-poor and one FeOrich) from the Renazzo-like carbonaceous (CR) chondrites Graves Nunataks 95229, Grosvenor Mountains 03116, Pecora Escarpment 91082, and Queen Alexandra Range 99177.

TL;DR: In this paper, an additive positive bias in the expectation value of the estimated ratio that is approximately equal to the true ratio divided by the counts of the denominator isotope of an individual ratio was shown.
