英文原文：
This image of a cluster of rocks labeled ’Rock Garden’ is where NASA’s Mars Exploration Rover Spirit became embedded in April 2009. The Spirit and Opportunity rovers landed on the Red Planet in January 2004 for what was to be a 90-day mission, but which has lasted 6 Earth years, or 3.2 Mars years. During this time, Spirit has found evidence of a steamy and violent environment on ancient Mars that is quite different from the wet and acidic past documented by Opportunity, which has been operating successfully as it explores halfway around the planet.
Spirit used its navigation camera to capture this view of the terrain toward the southeast from the location it reached on the 1,870th Martian day, or sol, on April 7, 2009.
Wheels on the western side of the rover broke through the dark, crusty surface into bright, loose, sandy material that was not visible as the rover approached the site. Spirit became stuck in an area near the left of the image’s center later in April.

这幅满是石头，名为“石头花园”的照片，由美国宇航局的火星探测器“勇气号”着陆后摄于2009年4月。勇气号与机遇号探测器在2004年1月登上这红色星球，计划执行一项为期90天的任务，结果这任务持续了地球历6年，或者说3.2个火星年。在这期间，勇气号发现了证明古代火星曾有着冒着蒸气、气候极端的环境，这和环绕火星探测任务已经过半的机遇号先前提交的报告中所谓潮湿，含酸的情形大相径庭。
着陆后第1870个火星天，即2009年4月7日，勇气号用其导航摄像机抓拍到着陆点东南方向的地表景象。
探测器西侧轮子变得异常黑暗，坚硬的外壳变成明亮、松散如沙的材料；因此探测器不再像着陆初时那么显眼。四月下旬，勇气号卡在照片所示地区中央偏左的某个地区
