[Off-Topic] Drilling into the Earth's mantle
http://www.smithsonianmag.com/science-nature/decades-long-quest-drill-earths-mantle-may-soon-hit-pay-dirt-180957908/
Since the 1960s, researchers have attempted to drill into
Earth's mantle but have not yet met with success. Some efforts
failed due to technical problems; others have fallen prey to
various sorts of bad luck--including, as discovered after the
fact, picking inopportune spots to drill. Nevertheless, those
efforts have shown that the technology and expertise to drill to
the mantle exists. And now the first phase of the most recent
attempt to reach this important part of our planet is boring
through a thin section of ocean crust in the southwestern Indian
Ocean.
