Drilling for what is set to be China’s deepest ever borehole began in the country’s oil-rich Xinjiang region on Tuesday, according to the official Xinhua News Agency. Earlier that morning, China sent its first civilian astronaut into space from the Gobi Desert. The narrow shaft into the ground will penetrate more than 10 continental strata, or layers of rock, according to the report, and reach the cretaceous system in the Earth’s crust, which features rock dating back some 145 million years. --- ### More from TIME --- “The construction difficulty of the drilling project can be compared to a big truck driving on two thin steel cables,” Sun Jinsheng, a scientist at the Chinese Academy of Engineering, told Xinhua. President Xi Jinping called for greater progress in deep Earth exploration in a speech addressing some of the nation’s leading scientists in 2021\. Such work can identify mineral and energy resources and help assess the risks of environmental disasters, such as earthquakes and volcano eruptions. The deepest man-made hole on Earth is still the Russian Kola Superdeep Borehole, which reached a depth of 12,262 meters (40,230 feet) in 1989, after 20 years of drilling. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/6284032/china-drill-hole-xinjiang/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/6284032/china-drill-hole-xinjiang/"},"headline":"Why Is China Drilling a 33,000-Feet Hole in Xinjiang?","datePublished":"2023-06-01T06:09:04.000Z","dateModified":"2026-02-24T15:57:57.236Z","description":"The narrow shaft will penetrate over 10 continental strata and reach the cretaceous system that features rock dating back 145 million years.","url":"https://time.com/6284032/china-drill-hole-xinjiang/","keywords":["China","wire"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt1dc158e381374832/698a3d7a929fad546fbf9e06/GettyImages-12583007971.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Yihui Xie / Bloomberg"}],"articleSection":"World","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt1dc158e381374832/698a3d7a929fad546fbf9e06/GettyImages-12583007971.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"XINJIANG DRILLING","caption":"XINJIANG DRILLING","creditText":"Li Xiang—Xinhua/Getty Images","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/world/","name":"World"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/china/","name":"China"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/6284032/china-drill-hole-xinjiang/","name":"Why Is China Drilling a 33,000-Feet Hole in Xinjiang?"}}]},{"@context":"https://schema.org","@type":"VideoObject","name":"China's Aggressive Maneuver Against U.S. Spy Plane Highlights Escalating Tensions","description":"A Chinese fighter jet conducted what U.S. military officials called an aggressive midair intercept of an American surveillance plane as it flew over the South China Sea on Friday, the latest in a series of incidents in the region between the two powers.","thumbnailUrl":"https://cdn.jwplayer.com/v2/media/dALSvsYI/poster.jpg?width=720","uploadDate":"2023-05-30T22:19:47.000Z","contentUrl":"https://cdn.jwplayer.com/manifests/dALSvsYI.m3u8","embedUrl":"https://time.com/6284032/china-drill-hole-xinjiang/","duration":"PT1M25S","potentialAction":{"@type":"SeekToAction","target":"https://time.com/6284032/china-drill-hole-xinjiang/?jw_start={seek_to_second_number}","startOffset-input":"required name=seek_to_second_number"}}] ```
