国际罗塞塔飞行任务是欧洲航天局科学方案的基石飞行任务，于2004年3月2日发射，这是其10年来与丘留莫夫-格拉西缅科彗星会合的旅程。一旦在2014年夏天到达彗核，Rosetta将围绕它运行大约1.5年，直到几公里的距离，并将一个名为Philae的着陆器发射到它的表面。在飞行的第一年，航天器及其有效载荷经历了广泛的调试工作，几次弹道修正演习，第一次地球重力辅助演习(发射一年后)，以及一些重要的科学操作。航天器终于在2005年7月底进入了第一个被动巡航阶段。本文介绍了在2004年10月中旬完成试飞活动后，在常规飞行的第一年中收集的飞行任务操作经验。描述了在此期间发生的两个主要飞行任务事件：2005年3月的第一次绕地球飞行和2005年7月的科学深度撞击观测活动。概述了飞行中的主要异常情况，并介绍了吸取的教训。
The International Rosetta Mission, a cornerstone mission of the European Space Agency Scientific Programme, was launched on 2nd March 2004 on its 10 years journey towards a rendezvous with comet Churyumov–Gerasimenko. Once reached the comet nucleus in summer 2014, Rosetta will orbit it for about 1.5 years down to distances of a few kilometers and deliver a Lander, named Philae, onto its surface. In its first year of flight, the spacecraft and its payloads have gone through an extensive commissioning exercise, several trajectory correction manoeuvres, the first Earth gravity assist manoeuvre (1 year after launch), and some important scientific operations. The spacecraft has finally entered its first Passive Cruise phase end of July 2005. This paper describes the mission operations experiences collected during the first year of routine flight, after completion of the commissioning activities mid-October 2004. The two main mission events that occurred during this period are described: the first Earth swing-by in March 2005 and the scientific Deep Impact observation campaign in July 2005. An overview of the major in-flight anomalies is given and lessons learnt are presented.
