Theres nothing as secure, Thanga said, adding that it serves as an insurance policy in the event of global catastrophe. Because once its lost its lost forever. University doctoral candidate Alvaro Diaz-Flores Caminero and undergraduate student Claire Pedersen were the lead authors of the paper.
The wiretap estimate for the crater is 21.2 kilometers.
