in 1958. In the R-2 and R-5 rockets, the dogs were contained in a pressured cabin. Dezik, Tsygan, and Lisa-1 Dezik (Дезик) and Tsygan (Цыган, "Gypsy") were the first dogs to make a sub-orbital flight on 15 August 1951. Both dogs were recovered unharmed after travelling to a maximum altitude of . Dezik made another sub-orbital flight in 1951 with the first dog named Lisa (Лиса, "Fox"), although neither survived because the parachute failed to deploy. After the death of Dezik, Tsygan was adopted as a pet by Soviet physicist Anatoli Blagonravov. Lisa-2 and Ryzhik Lisa-2 (Лиса, "Fox" or "Vixen") and Ryzhik (Рыжик, "Ginger" (red-haired)) flew to an altitude of on 2 June 1954. Smelaya and Malyshka Smelaya (Смелая, "Brave" or "Courageous", fem.) was due to make a flight in September but ran away the day before the launch. She was found the next day and went on to make a successful flight with a dog named Malyshka (Малышка, "Baby"). They both crashed after the rocket failed to deploy a parachute, and were found the next day by the recovery team. Bobik and ZIB Bobik (Бобик, common Russian name for a small dog) ran away just days before his flight was scheduled to take place on 15 September 1951. A replacement named ZIB (ЗИБ, a Russian acronym for "Substitute for Missing Bobik", "Замена Исчезнувшему Бобику" Zamena Ischeznuvshemu Bobiku), who was an untrained street dog found running around the barracks, was quickly located and made a successful flight to 100 km and back. Otvazhnaya and Snezhinka Otvazhnaya (Отважная, "brave one", fem.) made a flight on 2 July 1959 along with a rabbit named Marfusha (Марфуша, "little Martha") and another dog named Snezhinka (Снежинка, "Snowflake"). She went on to make 5 other flights between 1959 and 1960. Albina and Tsyganka Albina (Альбина) and Tsyganka (Цыганка, "Gypsy girl") were both ejected out of their capsule at an altitude of and landed safely. Albina was one of the dogs shortlisted for Sputnik 2, but never flew in orbit. Damka and Krasavka Damka (Дамка, "queen of checkers") and Krasavka (Красавка, "little beauty" or "Belladonna") were to make an orbital flight on 22 December 1960 as a part of the Vostok programme which also included mice. However their mission was marked by a string of equipment failures. The upper-stage rocket failed and the craft re-entered the atmosphere after reaching a sub-orbital apogee of . In the
