1 Jesús Martínez-Frías, Patrick McGuire & Javier Martin With the collaboration of Javier Gómez-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...” Centro de Astrobiología Near I-R spectroscopy experiment

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

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.
