Chicxulub 'Dino' Crater drilling project declared successful

The Chicxulub Crater on the coast of Mexico is an impact crater that is buried deep below the Yucatán Peninsula.

Around 66 million years ago, an asteroid called 'Chicxulub impactor', caused the hole that is 100 kilometers in diameter and 30 kilometers in depth.

The diameter of the space object that hit the Earth's surface is believed to be at least 18 kilometers.

The Chicxulub Crater is dubbed as the 'Lunar Twin' because of its striking resemblance to the Schrödinger crater on the farther side of the moon.

The asteroid penetrated deep below the Earth's surface digging a hole in such a way that the excavated material bounced back to form a ring.

These features are buried deep underwater, below the sediments, millions of years old.

The asteroid is believed to have slammed into Earth in the 'Cretaceous Period' leaving a 200-km wide and 30-km deep crater.

According to scientists, the debris caused by the impact would have darkened the sky and decreased the temperatures for several months together.

Scientists believe that because of the after effects of the space impact, dinosaurs and several other creatures were driven to extinction.

2010: An expert-panel confirmed that a space impact caused the mass extinction of dinosaurs.

2011: Proposal to study the Chicxulub Crater by drilling 1.5-km deep into the sea was suggested.

2013: Scientists first established that the dinosaurs died out about 66,038,000 years ago.

5 Apr'16: As a part of the International Ocean Discovery Program (IODP), the project to drill into the crater went underway.

A UK/US-led team declared that the attempt to drill into Mexico's Chicxulub Crater has been an outstanding success.

The team had cored into the deep 66-million-year-old crater for seven weeks and pulled up rocks from at least 1,300 meters below the Gulf seafloor.

The collected rock samples are expected to throw light on the level of impact and its effects on the environment.

According to project officials, the target originally was to drill 1,500 metres into the crater through the 'peak ring'.

The 'peak ring' is located in the centre of the crater's impact hole, where the Earth is believed to have rebounded after being hit by the massive asteroid.

The original target couldn't be reached, but rock samples from the 'ring' were collected.

The collected rock samples were encased in metal and stored in a refrigerated container.

These rocks would be transported back to the land and sent for CT scanning to examine their interior structure in the US.

Later, they would be taken to the Bremen city in Germany where the current science team's 33 members would conduct several tests on the rocks.
