I wonder if that dog's carcass is still orbiting the earth.
"Laika died a few hours after launch from stress and overheating, probably due to a malfunction in the thermal control system. The true cause of her death was not made public until decades after the flight."
better to burn up than slowly starve to death orbiting the earth. There were no plans to bring back that dog to tera firma.
this is a pretty cool book
