During this time there were two world powers: US and USSR, both with a totally different lifestyle (democracy and communism). The space race showed USSR was more advanced then we in the United States. It showed the rest of the world that communism was the way to go, and then the red scare and domino effect started coming around.
T means the Time of launch -- when the launch is planned to happen. T minus is the number of seconds before the rocket is to launch. T minus four seconds and counting means it is four seconds in the sequence of event before launch will occur and progressing toward that launch. T minus four seconds and holding means it is four seconds before launch in the sequence of events that precede launch and the progress toward launch has stopped. The hold/delay can be most any length of time, but once counting begins again it will still be four seconds until launch -- that is, they pick up where they left off and continue toward launch.There are both planned holds (to give everyone time to evaluate things) and unplanned holds when something is wrong. After launch it becomes T plus so many seconds. Actions during launch happen so many seconds after launch. For example, on a Space Shuttle launch, the Solid Rocket Boosters will separate from the Shuttle at T plus so many seconds.
It shocked the American scientific community, and also the US military and government, who hadn't realized the Soviets were that far advanced technologically; the big fear was that the next space launch might contain a nuclear bomb, which could be exploded over an American city, or fired toward it. The Soviets might also try to colonize or control access to outer space. Prior to the Sputnik launch, America hadn't taken space science very seriously; afterward, it became a high priority. Future President Lyndon B. Johnson (then a Senator) was quoted as saying "I for one do not want to go to bed by the light of a Communist moon." After his election, President John F. Kennedy vowed to put a man on the moon within 10 years. He knew that we were behind the Russians in putting a man into space. So he raised the goal higher. Out of this achievement, many new technological inventions were born.
The US Apollo projects were geared toward landing man on the moon. They lasted from 1963 to 1972, with six successful moon landings from '69 to '72. The Russian Sputnik went up in 1957. Both countries were involved in the competitive "Space Race" during those years. Eventually, in 1975, the co-operative Apollo-Soyuz Test Project human spaceflight mission occurred.
Gravity is a characteristic of space. Because of it, every material object encounters a force of attractiontoward every other material object. That leads to some interesting consequences:-- A satellite is attracted toward the earth.-- You are attracted toward the earth.-- The earth is attracted toward a satellite.-- A satellite is attracted toward you.-- The earth is attracted toward you.-- You are attracted toward a satellite.-- Two satellites are attracted toward each other.-- You are attracted toward Mars.-- The sun is attracted toward you.-- The sun is attracted toward a satellite.-- The sun is attracted toward my dog.-- You are attracted toward my dog, and also toward the sun.-- My dog is attracted toward Pres. Obama's golf balls....etc.
The force that pulls an object toward earth also pulls the earth toward the object.The two forces are equal. Together, we refer to them as the force of gravity.
It became clear in the 1950's, particularly after the launch of the Soviet satellite Sputnik, that science and math were going to play a crucial role in the progress of the Cold War.

rom 1946, the NACA had been experimenting with rocket planes such as the supersonic Bell X-1.[15] In the early 1950s, there was challenge to launch an artificial satellite for the International Geophysical Year (1957"58). An effort for this was the American Project Vanguard. After the Soviet launch of the world's first artificial satellite (Sputnik 1) on October 4, 1957, the attention of the United States turned toward its own fledgling space efforts. The U.S. Congress, alarmed by the perceived threat to national security and technological leadership (known as the "Sputnik crisis"), urged immediate and swift action;
You retrieve the missle launcher then guide it toward the missle and make sure it hits it.
It was the Allie's first step in their march toward Germany.
By tilting your device, move the can in front of the door, then tilt your device toward you so the can moves TOWARD you. Then launch the can into the door by tilting your device away from you. See related link for screenshots.
