Beagle 2 是欧空局火星快车任务（2003 年发射）着陆器部分的名称。 Beagle 2 号的主要目标是确定火星上是否存在过去存在生命的令人信服的证据，或者评估条件是否合适。 Beagle 2 号还计划进行一项全球响应测试，看看火星上目前是否存在任何生物活动。为了实现这些目标，Beagle 2 的 29 公斤有效载荷质量包括 7 公斤科学仪器，包括：气体分析包 (GAP)、穆斯堡尔和 X 射线光谱仪、环境传感器、全景和广角相机以及显微镜。地表和地下土壤将通过一种名为 Mole 的设备收集，同时仪器可以通过机械臂放置在适当的岩石表面上，通过研磨机去除风化产物。GAP 可以研究岩石内部的取芯样本。 Beagle 2 号的整体调查预计将持续 180 个太阳，不过也正在考虑延长任务场景。 (C) 2002 Elsevier Science Ltd. 保留所有权利。
Beagle 2 is the name given to the lander part of the ESA Mars Express mission (launch 2003). The main focus of Beagle 2 is to establish whether there is convincing evidence for past life on Mars, or to assess if the conditions were ever suitable. Beagle 2 also plans a globally responsive test to see if there is any present-day biological activity on Mars. To achieve these objectives, the 29 kg payload mass of Beagle 2 includes 7 kg of scientific instruments, including: Gas Analysis Package (GAP), Mossbauer and X-ray Spectrometers, Environmental Sensors, Panoramic and Wide Angle Cameras and a Microscope. Surface and sub-surface soils will be collected by a device called the Mole, whilst instruments can be placed by a robotic arm onto appropriate rock surfaces freed of weathering products by a grinder Cored specimens from the interiors of the rocks can be studied by the GAP. The overall Beagle 2 investigations are expected to last 180 sols, although extended mission scenarios are also being considered. (C) 2002 Elsevier Science Ltd. All rights reserved.
