Dogs were flown to an altitude of 100 km on board 15 scientific flights on R-1 rockets from 1951 to 1956. The dogs wore pressure suits with acrylic glass bubble helmets. From 1957 to 1960, 11 flights with dogs were made on the R-2A series, which flew to about 200 km. Three flights were made to an altitude of about 450 km on R-5A rockets in 1958. In the R-2 and R-5 rockets, the dogs were contained in a pressured cabin.
