Broadcasters who use satellites canít accept shutdowns, even when they happen only twice a year during eclipses. The Optus D3 satellite made by Orbital Sciences Corp. will use rechargeable lithium-ion batteries from Saft for power when the spacecraft is blocked from the sun during two eclipses.

It carries 32 transponders that will provide Ku-Band direct television broadcasting services to Australia and New Zealand after 2009.
