It was carrying three GLONASS (Russian GPS, sometimes combined with traditional GPS for improved accuracy, fix time etc - e.g. iPhone 4S/5) satellites. The loss of another three in 2010 was estimated to cost up to $160 million[1]. Expensive, but presumably nothing crippling in the scheme of things ($4.6 billion spent on the program from 2001-2011 [1])
