ASTRO-F 是日本红外天文卫星。该任务目的是进行红外巡天,其灵敏度和空间分辨率比之前的IRAS巡天任务高得多。 ASTRO-F 有一个液氦冷却望远镜,孔径为 68.5 厘米。轻型液氦低温恒温器是为 ASTRO-F 开发的。低温冷却器和其他设计特点的使用将仅用170升液氦实现在轨550天的制冷剂寿命。姿态控制系统提供连续天空勘测和指向观测的能力。姿态控制的绝对精度约为10角秒,稳定性优于1角秒。天文数据将通过X波段链路以4Mbps的速率发送到地面。每天的遥测数据量超过 2 GB。原定发射日期为2004年2月,但由于望远镜系统的镜面支撑机构出现故障而推迟。虽然新的发布日期尚未正式确定,但目前的目标是 2005 年夏季发布。
ASTRO-F is the Japanese infrared astronomical satellite. The mission purpose is the infrared sky survey with much higher sensitivities and spatial resolutions than those of the previous survey mission IRAS. The ASTRO-F has a liquid-helium cooled telescope with an aperture of 68.5 cm. The lightweight liquid helium cryostat has been developed for the ASTRO-F. The use of cryocoolers and other design features will realize the cryogen life of 550 days in orbit with only 170-liter liquid helium. The attitude control system provides capabilities of a continuous sky survey and also pointing observations. The absolute accuracy of the attitude control is approximately 10 arcsec, and the stability is better than 1 arcsec. The astronomical data will be sent to the ground in the rate of 4 Mbps through the X-band link. The telemetry data amount to more than 2 GB per day. The planned launch date was February 2004, but it has delayed because of a failure in the mirror support mechanism of the telescope system. Though the new launch date has not been decided formally, the launch in 2005 summer is now targeted.
