Kosmos 110 (Russian: Космос 110 meaning Cosmos 110) was a Soviet spacecraft launched on 22 February 1966 from the Baikonur Cosmodrome aboard a Voskhod rocket. It carried two dogs, Veterok and Ugolyok.


It incorporated a re-entry body (capsule) for landing scientific instruments and test objects. It was a biological satellite that made a sustained biomedical experiment through the Van Allen radiation belts with the dogs Veterok and Ugolyok. On March 16, after 22 days in orbit around the Earth, they were safely landed.[1]

This spaceflight of record-breaking duration was not surpassed by humans until Soyuz 11 in June 1971, and still stands as the longest space flight by dogs.[citation needed]
