متن کاملIsotopic compositions of cometary matter returned by Stardust.
Hydrogen, carbon, nitrogen, and oxygen isotopic compositions are heterogeneous among comet 81P/Wild 2 particle fragments; however, extreme isotopic anomalies are rare, indicating that the comet is not a pristine aggregate of presolar materials. Nonterrestrial nitrogen and neon isotope ratios suggest that indigenous organic matter and highly volatile materials were successfully collected. Except...

متن کاملProtocol for Future Amino Acid Analyses of Samples Returned by the Stardust Mission
Introduction: The delivery of amino acids to the early Earth by interplanetary dust particles, comets, and carbonaceous meteorites could have been a significant source of the early Earth's prebiotic organic inventory [1]. Amino acids are central to modern terrestrial biochemistry as major components of proteins and enzymes and were probably pivotal in the origin of life. A variety of amino acid...
