This deceleration is again 1 within the tolerance limits of men properly supported in a nearly prone position. After peak deceleration ,the satellite will gradually slow up to a very low speed and the parachute will return it gently to the earth. The falling phase will take about one-half hour.

Thus, it appears that at the present time no great scientific discoveries are needed to achieve manned space flight. Ifc thus becomes a matter for decision. Is America willing to pay for it? It is not yet.clear how or whether manned space flight will be important in a military sense.. Histori- .cal perspective in this respect can be useful to supplement the deficiencies in our imagination. Some of the revolutionary weapons of this century were the airplane, radar, nuclear energy.
