Preliminary SEM/EDAX studies of the Tissint meteorite shows projections of
interior spherical globules rich in C and O. Such concentrations of carbonaceous material in
a matrix of mineral grains poses a mystery if biological processes are excluded. They are
consistent with remnants of biological structures, thus supporting earlier similar claims for
the Mars meteorite ALH84001
Tissint, 29°28.917’N, 7°36.674’W
Tata, Morocco, Fell: 18 July 2011
Tissint is the fifth Martian meteorite fall. A
fireball was observed by people from Tata city and some nomads on July 18th 2011 at about 2:00 am; first samples were recovered by hunters at the end of October 2011 on the Oued Drâa area.
At the 41st annual meeting of the Division for Planetary Sciences of the American Astronomical Society Sunday October 4 to Friday October 9, 2009 at El Conquistador Resort, in Fajardo, Puerto Rico, USA there was a scientist who reported on the recovery of a meteorite that was seen just prior to entry and successfully tracked. Here is part of what he presented. We report on the recovery of fragments from 2008 TC3, a small asteroid that impacted over northern Sudan on October 7, 2008. This was the first asteroid detected prior to impact and now also the first asteroid observed in space for which meteorites could be recovered. We interviewed eye witnesses of the fireball, who confirmed that the impact resulted in an explosion around 37 km high in the atmosphere, with no luminosity below 32 km. This is a behavior more typical of impacting comets than asteroids (fireball PE type IIIa/b). Never before had meteorites been recovered from an object exploding this high in the atmosphere. Nevertheless, 45 students and staff of the University of Khartoum were brought to the area just downstream of the explosion location, some 30 kilometers into the desert from the railroad track at Station 6 ("Almahata Sitta"). After two hours of searching on December 5, the first meteorite was recovered by Mohammed Alameen.
