NASA says its Mars rover Curiosity has used its drill for the first time to hammer briefly into a rock targeted on the floor of its Gale Crater landing site.

“Before and after” images beamed to Earth showed the results as an indentation on the surface of the rock.

The drill instrument is capable of both hammering and rotating actions, and if the rock is determined to be a good candidate for the rover‘s scientific work, a number of test holes will be drilled, NASA said, to create samples for delivery to the rover’s onboard laboratories.

They would be analyzed as part of the rover‘s main mission to determine whether the Gale location has ever been capable of supporting bacterial life.

“The rock is behaving well and it looks pretty soft, so that’s encouraging,” Curiosity project scientist Professor John Grotzinger told BBC News.

The first drilling is being carried out on a very fine-grained sedimentary rock, NASA said.

“The drilling is going very well so far and we‘re making great progress with the early steps,” Grotzinger said. (UPI)

최초! 화성 지표면 뚫어보니

나사(NASA)는 화성탐사선 큐리오시티(Curiosity)가 화성 지표면 관측을 위해 최초로 드릴을 사용해 표면을 뚫었다고 전했다.

드릴 장비는 바닥에 충격을 가하고 회전 운동이 가능하다. 채취한 표면 물질이 과학적 연구 가치가 있을 경우 드릴을 이용해 계속해서 구멍을 뚫을 계획이다.

화성의 지표면 연구는 박테리아가 생존 가능한 환경인가를 알아보기 위해 진행되고 있다.

"표면이 생각보다 부드럽더군요. 긍정적인 결과입니다."라고 큐리오시티 프로젝트 담당인 존 그로트징거(John Grotzinger) 교수가 BBC와의 인터뷰에서 밝혔다.

탐사한 표면은 가는 입자의 퇴적암이었다고 나사가 전했다.

"드릴 작업은 성공적이었고요. 좋은 출발입니다."라고 그로트징거가 언급했다. (코리아헤럴드)
