The uncertainty of science: Even as NASA officials poo-poo the suspected meteorite impact in India that killed a bus driver, India scientists have done a chemical analysis of one of the rocks found near the site and found it to be a meteorite fragment.
According to a preliminary report by National College Instrumentation Facility (NCIF) in Trichy, a Scanning Electron Microscope (SEM) study on samples retrieved from the campus in Vellore where the blast occurred shows the “presence of carbonaceous chondrites”.
“Carbonaceous denotes objects containing carbon or its compounds and chondrites refer to non-metallic meteorite parts containing mineral granules,” K Anbarasu, a geologist who is also principal of the Trichy-based National College, told The Indian Express.
There remains uncertainty because the fragments tested did not actually come from the impact crater itself.
Anbarasu said the preliminary SEM study was conducted on “small pieces of black material” found near the blast site. “The crater formed at the spot had been already disturbed by other investigators. So we inspected the entire campus as any meteor incident would scatter several objects across the area before landing. Finally, we spotted several small pieces of this black material, one the size of a paperweight, on the terrace of a building nearby,” Anbarasu said.
Nonetheless, I think it unprofessional and inappropriate for a NASA official to comment on this event half a globe away. There is no way that they can really determine anything from the available photos taken of the impact site, and thus they should shut up.
