Found the nozzle by Gustav DeLaval obtained efficiencies up to 63%
Experiments showed that rockets could work in a vacuum
It was possible to achieve escape velocity with a rocket
Optimum efficiency would be produced from a multi-staged rocket
Shared his results with the Smithsonian Institution in Washington
he wanted support to build a rocket that could reach the high atmosphere
1917 the Smithsonian responded with a grant of $5000

The Cold War<br /><ul><li>The Cold war was an era of conflict, tension and competition between the United States and the Soviet Union. It started in mid-1940s and lasted till the early 1990s.
One of the ways the two superpowers competed was the Space Race.
The Space Race was initiated on October 4, 1957 by the Soviet Union, when they launched Sputnik 1.
The launch caused a huge shock to the United States. It was through that the United States was no longer safe behind its ocean barriers. The Soviet Union could launch missiles directly on United States. </li></li></ul><li>The Space Race<br /><ul><li>On April 12, 1961 the Soviets launch another satellite, Sputnik 2. This time they were able to put a dog in orbit around the earth. The flight lasted for 1 hour and 48 minutes.
The first step that the United States made in catching up to the Soviets was in the successful launch of Alan Shepard into space on May 5, 1961
Then President Kennedy gave a speech on May 25, 1961 which challenged to travel to the moon by the end of the decade, congress fully funded NASA to get this accomplished. </li></li></ul><li>USA vs. USSR<br /><ul><li>While both sides were advancing in technology at the same time they had a few setbacks.
USA: The first Apollo mission on January 27, 1967 was a tragic failure.
USSR: 1967, a Soviet spacecraft, Soyuz 1 was landing and had control failure then crash landed. As for the passenger, Cosmonaut Komarov, he was unable to survive the crash. </li></li></ul><li>The United States During the Space Race<br /><ul><li>Attempts to launch a satellite

Astronauts Neil Armstrong and Buzz Aldrin were the first men on the Moon.
Though the landing on the moon ended the Space Race, NASA and the Soviets continued to develop their space technology and began working on a project, Apollo-Soyuz which eased tensions between the two nations.
The success of Apollo-Soyuz mission essentially put the Cold War on hold long enough for the two rival nations to prove that they could successfully work together. </li></li></ul><li>First Time Space Achievements<br />Soviet Union Firsts<br />United States Firsts<br /><ul><li>Satellite
As these new thoughts began to make news, they caused the Sci-Fi era</li></li></ul><li><ul><li>Since people were overly </li></ul>interested in space and what it <br />may hold, authors like H.G. Wells<br />began writing about fantastic accounts of extra terrestrial activity.<br /><ul><li>H.G. Wells’ WAR OF THE WORLDS raised people’s fears of alien invasion
More and more films and novels were being written about aliens and outer space</li></li></ul><li><ul><li>In Roswell, New Mexico an </li></ul>unidentified object crash landed in<br />an open field in July 1947<br /><ul><li>Because of the new fears of outer </li></ul>space, the Roswell incident exploded into fame<br /><ul><li>People feared that either the Soviet Union had some part in the incident or the wreckage was of alien decent
All of the questions rose because of the fears caused by the space race.</li></li></ul><li><ul><li>The space race also contributed</li></ul>to Area 51’s nation wide fame<br />because of all of the secrets <br />people began to wonder what went on there<br /><ul><li>Stories of alien corpse at Area 51 began getting more frequent
Since the US was looking to get the upper hand in space it was believed that the government held top secret UFO testing there</li></li></ul><li><ul><li>As a result of the new interest in the cosmos the Sci-Fi era was born
It’s impact on our culture is still visible today
Science Fiction is an extremely popular genre of movie and television show
The Space Race is solely responsible for creating extra terrestrial awareness, thus being the catalyst for what we know today as Science Fiction or Sci-Fi</li></li></ul><li>Future<br /><ul><li>Teamwork
