卫星延寿这事有个问题是，电子通讯技术10年变化也天翻地覆了，换电池不一定比换机器性价比高啊。

【 在 shallpi0n 的大作中提到: 】
: Northrop Grumman hit a new milestone in extending the life of active spacecraft as a purpose-built spacecraft, MEV-2, docking with Intelsat's IS-1002 satellite to give it another 5 years of life. It's a strong demonstration of the possibilities in a growing field of orbital servicing operations.
: MEV-2 launched in August and matched the orbit of Intelsat's 18-year-old satellite, which would have soon be due for decommissioning, having exceeded its original mission by some 5 years. But it's precisely this type of situation that the new "on-orbit service, assembly and manufacturing," or OSAM, industry intends to target, allowing such satellites to live longer — likely saving their operators millions.
: In last night's operation, the MEV-2 spacecraft slowly approached IS-1002 and docked with it, essentially adding itself as a spare engine with a full tank. It will stay attached this way for five years, after which it will move on to its next mission — another end-of-life satellite, probably. (I've asked for a few more details along these lines.)
