For the second year in a row, the 16 countries involved in the international space station have agreed to delay construction because of Russia's inability to pay its share.

Under the latest schedule, released Sunday, the space station should begin flying in November - one year late - and be completed in early 2004.The National Aeronautics and Space Administration estimates 43 flights will be needed to assemble the 1-million-pound outpost in orbit, two fewer flights than previously scheduled.

The Russians will launch nine flights, three fewer than before. To save money, they canceled two life-support modules and one stowage chamber. NASA, on the other hand, will launch 34 shuttle flights to haul up station parts, one more than before.
