原定今年2月份在美国加里福尼亚州西部试验场发射的红外天文卫星(以下简写为IRAS),已经被推迟。据参与卫星计划的人士透露,发射推迟的主要原因是:地面测试设备需要重新生产;有效载荷(望远镜)初级反射镜有裂痕需要处理。重新拟定的发射日期预计不会早于1982年8月份。本文将简单介绍IRAS计划概貌、总体设计主要数据、望远镜及其探测器、荷兰研制的补充试验设备、卫星本体各个分系统和卫星发射后的飞行控制及地面操作等。
The infrared astronomy satellite (hereinafter referred to as IRAS) originally scheduled for February this year at the western test site of the State of California in the United States has been postponed. According to sources involved in the satellite program, the main reasons for the postponement of launches were: ground test equipment needs to be re-produced; payload (telescope) primary mirror cracks need to be addressed. The rescheduled launch date is not expected to be earlier than in August 1982. This article provides an overview of the IRAS program overview, the main design data, telescopes and their detectors, supplementary test equipment developed in the Netherlands, subsystems of the satellite and flight control and ground operations after satellite launch.
