キュリオシティが火星に穴を開け始めた！ Originally shared by NASA Drill Test! Our Curiosity Mars rover completed a shallow "mini drill" activity on April 29, 2014, as part of evaluating a rock target called "Windjana" for possible full-depth drilling to collect powdered sample material from the rock's interior. This image from Curiosity's Mars Hand Lens Imager (MAHLI) instrument shows the hole and tailings resulting from the mini drill test. The hole is 0.63 inch (1.6 centimeters) in diameter and about 0.8 inch (2 centimeters) deep. When collecting sample material, the rover's hammering drill bores as deep as 2.5 inches (6.4 centimeters). This preparatory activity enables the rover team to evaluate interaction between the drill and this particular rock and to view the potential sample-collection target's interior and tailings. Both the mini drill activity and acquisition of this image occurred during the 615th Martian day, or sol, of Curiosity's work on Mars (April ...

NASA TVやってる。ちょうどいま拍手が起きた。 Originally shared by NASA Tonight starting at 11pm ET/8pm PT, join us for live NASA TV coverage of the landing of the Curiosity rover on Mars.  Watch at http://www.nasa.gov/ntv The #MSL  Mars Science Laboratory is the most ambitious, complex mission in the history of robotic space exploration. On August 5/6, 2012, the mission will set down a large, mobile laboratory - the dune buggy-sized Curiosity rover - using a new form of precision landing technology that makes many of Mars' most intriguing regions viable destinations for the first time.
