How Far Have We Drilled into the Earth?

Answer

In 2012, a new record was set off the coast of Japan where scientists drilled more than 2,111 meters in the earth to obtain rock samples. Scientists used a vessel named Chikyu which has been specially designed to drill down to 10,000 meters below sea level. Prior to the record set near Japan, the former record had been set near the Costa Rica Rift.
