Meteors: A Delivery Mechanism of Organic Matter to the Early Earthmeteors” in rarefied flows of high (up to 270) Mach number. The recent Leonid showers offered a first glimpse into the elusive physical conditions of the ablation process and atmospheric chemistry associated with high-speed meteors. Molecular emissions were detected that trace a meteor’s brilliant l

Search for Organic Matter in Leonid Meteoroidsnid meteor spectra at 387 nm. CN is an expected product of ablation of nitrogen containing organic carbon in the meteoroids as well as a possible product of the aerothermochemistry induced by the kinetic energy of the meteor. A slit-less spectrograph with objective grating was deployed on FISTA duri

Search for Extraterrestrial Origin of Atmospheric Trace Molecules — Radio Sub-Mm Observations duringof atmospheric HCN. HCN radio observations at CSO (Hawaii) on Nov 18/19, 1999, the night after the second Leonid shower maximum, show unusually low HCN abundances above 45 km altitude, which are only recovered after sunrise. We also investigated UARS/HALOE satellite data on H.O and O.. No correlatio

Lorentz Shaped Comet Dust Trail Cross Section from New Hybrid Visual and Video Meteor Counting Technoperators from airborne platforms. A total of 33,000 Leonids, recorded on video during the 1999 Leonid storm, were watched by a team of visual observers using a video head display and an automatic counting tool. The counts reveal that the activity profile of the Leonid storm is a Lorentz profile. By
