AVX Corporation.is celebrating the continuing success of NASA’s Curiosity rover (also known as the Mars Science Laboratory), which has spent roughly 2,100 Martian solar days — or sols, which comprise 24 hours, 39 minutes and 35.244 seconds — investigating the planet’s Gale Crater since it landed on August 6, 2012.
AVX开发并提供了630空间级，SRC9000 TBM系列UltraLow-ESR，多年达钽电容器这是负责发挥好奇心的Chemcam.激光模块，它是用于分析火星上岩石和土壤化学成分的化学和相机设备的组合，具体地研究该地区是否经历了有利于支持微生物生活的环境条件。自2012年8月20日第一次运行以来，ChemCam激光模块已触发超过500万次，当它通过烧制30次激光脉冲时询问称为加冠的拳头大小的岩石 - 每一个都提供超过一百万瓦的力量大约五十亿分钟 - 仅在10秒内。从那时起，ChemCam激光器通常在每天256到327次之间被射击，并导致许多显着的观察关于现在，更重要的是，红色星球的过去。
Chemcam通过将岩石和土壤目标的激光，成像仪和望远镜指向从其在地上的桅杆上的位置，将其激光，成像仪指向岩石和土壤靶标的位置，即在地上的6.6'（2m）;将其激光燃烧，蒸发小于0.04“（1mm）的目标，远离32'（1mm），并且在材料被电离时产生由其望远镜观察的光闪光;and transmitting the telescope’s observation, via optical fiber, to an onboard spectrograph that provides unprecedented detail about the minerals and microcultures in rock and soil samples by measuring the composition of the plasma (an extremely hot gas made of free-floating ions and electrons) resulting from the laser interrogation. The laser is also used to clear dust away from Martian rocks so the ChemCam’s remote camera can acquire extremely detailed images.
为了以成功完成其使命所需的极端精确度，ChemCam依赖于一系列被证明提供高可靠性，长寿命性能的电子元件阵列;在敌对，外星条件下表现出粗糙的环境耐药性，包括：温度，压力，紫外光和水蒸气的强烈季节变化;并且能够满足严格的空间和重量约束。
“ChemCam的持续成功展示了我们MNO的长期可靠性2-Cathode TBM系列多年子钽电容器，并进一步支持了我们严格的可靠性SRC9000space-level qualification and inspection process, which was developed especially for long-term, mission-critical applications and, in addition to the ChemCam, is used extensively on satellite programs,” said Brian Brunette, assistant quality and reliability manager for AVX’s tantalum division. “AVX is the world’s largest manufacturer of the high-reliability tantalum capacitors employed in mission-critical military and aerospace electronics, life-sustaining and implantable FDA Class III medical devices, and space-constrained, harsh-environment, safety-critical automotive electronics, including advanced driver-assistance systems (ADAS).”
