That project won't be surpassed by this new - admittedly massive - attempt. The deepest ever dug - the one that discovered the plankton - was in Russia.
The Kola Superdeep Borehole - just a really big hole in the ground - ended up reaching over 11,000 meters below sea level after being started by Soviet scientists in 1970. They had to abandon the project after hitting extremely high temperatures that they weren't expecting. Interesting.
The Chinese project isn't going to be easy. It's not as simple as digging straight down into the Earth's crust and hoping for the best. It's also extremely costly and time-consuming.
“The construction difficulty of the drilling project can be compared to a big truck driving on two thin steel cables,” Sun Jinsheng, an academic from the Chinese Academy of Engineering, told news agency Xinhua.
So yeah, they'll need more than a JCB for this.
