Jess Martnez-Fras, Patrick McGuire & Javier Martin With the
collaboration of Javier Gmez-Elvira, Franck Selsis, Rafael
Gomez-Blanco & Peter Jenniskens ...Spain is taking a leading
role in this year's Leonid MAC mission. The Centro de Astrobiologia
(CSIC/INTA) at Torrejon de Ardoz, near Madrid, will host the 2002
Leonid MAC deployment and participate key experiments on the DC-8
Airborne Laboratory. The Centro de Astrobiologia is a full partner
of NASA's Astrobiology Institute... http://leonid.arc.nasa.gov/

spectroscopy experiment Slide 2 METEORITES: acid-insoluble polymer,
hydrocarbons, monocarboxylic acids, primary alcohols, aldehydes,
ketones, amines, urea, purines, amino acids and carbonates. COMETS:
H, C, O, CN, CH, OH, H 2 O +, CN +, CH +, OH +, N 2 +, CO +, CO 2+
and complex organic molecules such as CH 3 CN, H 2 CO, and HCO
Slide 3 Fingerprints of organic matter were found in the trail of
this 1999 Leonid fireball, which endured to 55 kilometers (34
miles) above Earth, much lower than most Leonid meteors. The GIOTTO
probe traversed Halley's comet at high speed and was able to record
mass spectra of impacting dust particles. The majority of the dust
grains were found to be largely carbonaceous, justifying the
description "CHON" material from their elemental compositions.
