"The first living thing in space had been the Russian dog Laika.
She had died in orbit—had never come home.
If he glanced out at the star-speckled sky,
Gennady could almost see her ghost racing eternally through the heavens,
beside the dead dream of planetary conquest,
of flags planted in alien soil
and shining domes on the hills of Mars."
- Karl Schroeder, "Laika's Ghost"
