编辑: google了下 What could be happening out near the edge of the solar system? The 33-year-old Voyager 2 spacecraft has experienced an anomaly where the data it sends back is unreadable. To try and understand the problem, engineers at JPL have shifted the spacecraft into a mode where it transmits only spacecraft health and status data. Preliminary engineering data received on May 1 show the spacecraft is basically healthy, and that the source of the issue is the flight data system, which is responsible for formatting the data to send back to Earth. 官方的说法是经过转换入另一个检查用的模式,整个系统基本是正常的,只是负责传送前格式化数据的系统出了问题.
机载CPU系统,总共三种,每种2个 There are three different computer types on the Voyager spacecraft and there are two of each kind. Total number of words among the six computers is about 32K.
Computer Command System (CCS) - 18-bit word, interrupt type processors (2) with 4096 words each of plated wire, non-volatile memory.
Flight Data System (FDS) - 16-bit word machine (2) with modular memories and 8198 words each 出问题的是这个
Attitude and Articulation Control System (AACS) - 18-bit word machines (2) with 4096 words each.
