In all, there’s more than 10,000 dead spacecraft, rocket

bodies and other relics of the space age circling Earth, all of which present a

formidable challenge for governments, researchers and companies wishing to

operate satellites for remote sensing, science, communications and other

The dangers of space debris hit home last year when a

decommissioned Russian military satellite crashed into and destroyed one of

Iridium’s mobile communications spacecraft in what is believed to be the first

in-space collision.
