...both orbits were fast decaying toward the upper edge of the earth's atmosphere, where the capsules had to be brought down or run the risk of fiery destruction. Up flashed a message from the Russian ground control station to Popovich: "Since your meter shows low temperature and humidity, and considering that you have completed your mission, make preparations to land on the 49th orbit. Check your ship's interior safety belt, the safety belt key, the seat catapult switch and the condition of your space suit. The wind velocity at the landing site is seven to nine...
Minutes later, Nikolayev radioed in. "This is Falcon. Confirming landing at 6sth orbit. The pressure in the cabin is i.i, the temperature 11° (Centigrade, equal to 52° F.), and the humidity...
...launch window" (margin of time in which a missile can be launched to fulfill its mission) of a second rocket trying to match the orbit of a vehicle already in space is only a very few minutes. Yet the Russians scored a virtual bull's-eye. "The Russians must have multiple launch pads, because you can't refurbish a pad in 24 hours and then check out another rocket for launching in the same place," said one top U.S. space scientist. The extra pads serve Russia well in the event that a rocket malfunctions during countdown...
...days respectively and ate solid food also suggested that the Russians may have found a better way to dispose of or to store body wastes.- Equally important was the indication that Russia had licked the problem of space sickness. Gherman Titov's bout of nausea during his ly-orbit flight had raised serious doubts about man's physical ability to withstand the effects of prolonged weightlessness. But last year Soviet scientists toughened the cosmonauts' training program to help them combat space sickness. New whirling and loop-the-loop exercises were prescribed; after rigorous physical exertion, a cosmonaut...
...Base. Other U.S. scientists were less pessimistic. They emphasized that because Russia was still operating behind a curtain of secrecy, no one outside the Soviet Union could really gauge the scientific accomplishment of the two-man mission. The Russians did not announce the launchings until the capsules were in orbit, and kept strict control over all information. They did not reveal the size of either capsule, as they had done for the Gagarin and Titov flights,- and the names of the rocket designer and standby cosmonauts were not disclosed...
