A second battery has failed aboard the Russian component of the International
Space Station, leaving four out of the original six still working. Mission
controllers first noticed that the Zarya module鈥檚 batteries weren鈥檛 discharging
properly after its launch in late 1998. As a result, the computer controllers
that regulate the batteries were replaced in May. But it seems that this didn鈥檛
solve the problem.
