NEW DELHI • Indian scientists have expressed doubt that a man in the southern state of Tamil Nadu was the first person to have been confirmed killed by a meteorite strike, as the state's top official has declared.
The experts said the small crater, the absence of a sonic boom before impact, a lack of debris, and the green and blue colour of rock recovered from the scene suggest some other cause. "It is highly improbable, but we will only be absolutely sure after a chemical analysis," said Dr V. Adimurthy, a senior scientist at India's space agency.
The mysterious event has triggered an international debate about whether a meteorite, space debris, leftover explosives or even frozen waste from a plane passing overhead may have killed the man.
The meteorite attribution was made this week by Chief Minister Jayalalithaa Jayaram, a former film star who is known for her authoritarian style. She said a bus driver was killed by the meteorite at an engineering college in the state, and his family was awarded 100,000 rupees (S$2,050) in compensation.
Ms Jayalalithaa has a cult-like following in her state, with her pictures on prominent display in the offices of her party's politicians as a sign of their unquestioning loyalty.
Since her comments, state officials have been reluctant to discuss publicly what happened. A team of scientists from the Indian Institute of Astrophysics in Bangalore arrived in Tamil Nadu on Tuesday to inspect the 2m-wide crater and collect the recovered rock sample, which is small enough to fit in a hand. Dr G.C. Anupama, an astronomy professor at the institute, said the probe would focus on the chemicals in the debris as meteorites have high iron levels. She declined to comment on whether she believed the debris was a meteorite.
Mr C.B. Devgun, the president of non-government body Space who has been tracking meteorites for the last two decades, said the colour of the rock and absence of other particles ruled out a meteorite.
He said: "It was a greenish colour and no other pieces of debris were found. Normally it would be a darkish yellow or darkish black in colour, just like burned coal, with a slightly melted surface."
The last reported death from a meteorite strike was in 1825, according to a list maintained by International Comet Quarterly, a scientific journal. In 2013, a meteorite that exploded over central Russia rained down fireballs and caused a shock wave that smashed windows, damaged buildings and injured 1,200 people.
