Other Space Dogs
Between 1957 and 1966, the USSR (now Russia) sent 13 dogs into space in preparation for future missions. The dogs included:

• Laika (meaning "Barker") - died during a mission (Sputnik 2, November 1957)
• Lisichka (meaning "Little Fox") and Bars (meaning "Panther" or "Lynx") - died during a test flight on July 28, 1960
• Strelka (meaning "Little Arrow") , Belka (meaning "Squirrel"), 40 mice, 2 rats and a number of plants - safely recovered from Korabl'-Sputnik-2. Launched August 19, 1960, it orbited the Earth 18 times. This was the first successful recovery of living biological specimens after an orbital mission. Strelka later gave birth to a litter of 6 healthy puppies; one was given to President John F. Kennedy as a gift.
