Results of the first stage:

For the first time, the issue of survival of animals in a small-volume pressurized cabin during a flight of 100.8 km and a speed of up to 4212 km/h has been resolved.
And in the behavior and general condition of the animals during the flight, after the flight, no disorders were observed in the subsequent time.

The developed devices made it possible to record the frequency and depth of breathing, temperature, general condition and behavior of animals, as well as external factors during the flight:

The rescue system of the container of the rocket ensures the descent and landing of animals with reliable instruments.

The second phase of the research involved animal flights in pressurized cabins of single-stage R-2 and R-5 geophysical rockets to altitudes of 200-450 km. Dogs weighing 5-7 kg were chosen as experimental animals. The animals' pulse, blood pressure, and respiration were recorded, and their electrocardiograms were recorded. The dogs were filmed continuously throughout the flight.

Between 1948 and 1961, the USSR prepared and conducted 29 launches of geophysical rockets, and carried out flights of two artificial Earth satellites and four satellite spacecraft.

Five animals that flew to an altitude of 110 km were observed over a number of years. Neither their behavior, body weight, nor fur coloration changed significantly.
