加速器型孔隙度探测器 APS
在9分钟内，探测器必须将速度从每小时2万公里降至零，从火星上空125公里处着陆。
In nine minutes, the probe had to reduce its speed from 20,000 km per hour to zero, landing from 125 km above Mars.
除了备有灵敏的地震仪，地球物理监测站还将会使用一个装有温度计的探测器钻入地下20英尺（6米）以尝试着计算出温度随深度增加而升高的速度。
Along with sensitive seismographic equipment, GEMS will drill down about 20 ft. (6 m) with a thermometer-equipped probe, trying to figure out how quickly the temperature rises with depth.
探测器以每秒15公里(9英里)的速度通过小行星时，最近距其只有3160公里(1950英里)，而整个飞越仅耗时不到一分钟。
The spacecraft passed the asteroid at a minimum distance of 3,160 kilometers (1,950 miles) and at a velocity of 15 kilometers (9 miles) per second, completing the flyby in just a minute.
