A cryonics satellite was a type of artificial satellite, used on Earth during the late 20th century, to cryogenically preserve individuals who had passed away. They were equipped with solar panels, and divided into four interior sections. They held several cryogenically frozen Humans that had died of causes that the Humans believed would be treatable in the future. The SS Birdseye, discovered by the USS Enterprise-D in 2364 was one such example of this technology. (TNG: "The Neutral Zone" )
