Space Module Runs Into Minor Glitches

After a flawless launch, the first piece of the International Space Station has developed three minor problems, Russia’s top space official acknowledged. But he said the glitches would not affect operations. Neither Russia nor NASA, which is leading the $40-billion space station project, had reported any problems since the Russian-built Zarya, or Dawn, module entered orbit Friday. Now one of Zarya’s eight batteries is failing, and an antenna isn’t working properly. And the humidity level in Zarya’s cabin is higher than expected, Russian Space Agency chief Yuri N. Koptev said.
