摘要:

开普勒的主要任务是使用凌日法在晚型恒星的宜居带中寻找地球大小的系外行星。为了有效地完成这项任务,开普勒绕太阳运行,并几乎连续地盯着一个视场,这个视场是精心选择的,以提供适当的目标恒星密度。该任务设计所隐含的数据传输速率、操作周期和目标管理要求已得到优化,并被纳入科学操作的综合计划。调试阶段完成了所有关键任务,并在发射前计划的一周内实现了所有目标。自科学开始以来,标称数据收集时间轴已被两次安全模式事件、几次精细点丢失和一些小的指向调整中断。最重要的异常被理解和缓解,因此开普勒的技术性能指标在此期间有了显着改善,任务成功的预测非常好。开普勒数据档案馆建立和托管数据的科学团队,客人观察员,和公众。第一批公开的数据集包括每月发布的全帧图像、丢弃的目标和单个来源。每季度通过档案库发布数据;开普勒成果目录将从2011年开始每年发布。

英文摘要:

Kepler's primary mission is a search for earth-size exoplanets in the habitable zone of late-type stars using the transit method. To effectively accomplish this mission, Kepler orbits the Sun and stares nearly continuously at one field-of-view which was carefully selected to provide an appropriate density of target stars. The data transmission rates, operational cycles, and target management requirements implied by this mission design have been optimized and integrated into a comprehensive plan for science operations. The commissioning phase completed all critical tasks and accomplished all objectives within a week of the pre-launch plan. Since starting science, the nominal data collection timeline has been interrupted by two safemode events, several losses of fine point, and some small pointing adjustments. The most important anomalies are understood and mitigated, so Kepler's technical performance metrics have improved significantly over this period and the prognosis for mission success is excellent. The Kepler data archive is established and hosting data for the science team, guest observers, and public. The first data sets to become publicly available include the monthly full-frame images, dropped targets, and individual sources as they are published. Data are released through the archive on a quarterly basis; the Kepler Results Catalog will be released annually starting in 2011.
