A series of shock experiments were conducted to assess thefeasibility of the delivery of organic compounds to theEarth via cometary impacts. Aqueous solutions containingnear-saturation levels of amino acids (lysine, norvaline,aminobutyric acid, proline, and phenylalanine) were sealedinside stainless steel capsules and shocked by ballisticimpact with a steel projectile plate accelerated along a12-m-long gun barrel to velocities of 0.5–1.9 km sec-1. Pressure-temperature-time histories of the… CONTINUE READING
