Satellite states
Spacecraft launches over the past decade
SPACE is not a two-horse race. Although America and Russia, the traditional
space-race adversaries, have launched more spacecraft than any other
countries, a slew of smaller players are nipping at their heels. According
to Futron, a consultancy, in 2010 China launched more rockets than America,
for the first time ever. Russia remains top, thanks in no small part to its
commanding position in the commercial launch market, where its cheap and
reliable rockets have attracted a lot of business. Last year 13 out of 26
such launches were Russian. The launch business is unpredictable, and the
small volumes mean that numbers can fluctuate from year to year. The
military-launch side of the business, in particular, tends to move in cycles
, as new generations of satellites are developed, deployed and then replaced
