The Space Race was a 20th-century competition between two Cold War rivals, the Soviet Union (USSR) and the United States (US), for supremacy in spaceflight capability. It had its origins in the missile-based nuclear arms race between the two nations that occurred following World War II, aided by captured German missile technology and personnel from the Aggregat program.

“On the flight back from Moscow, Musk realized that he could start a company that could build the affordable rockets he needed.[58] According to early Tesla and SpaceX investor Steve Jurvetson,[59] Musk calculated that the raw materials for building a rocket actually were only 3 percent of the sales price of a rocket at the time. By applying vertical integration and the modular approach from software engineering, SpaceX could cut launch price by a factor of ten and still enjoy a 70-percent gross margin.[60] Ultimately, Musk ended up founding SpaceX with the long-term goal of creating a "true spacefaring civilization".[61]

The Voyager Golden Records are phonograph records that were included aboard both Voyager spacecraft launched in 1977. They contain sounds and images selected to portray the diversity of life and culture on Earth, and are intended for any intelligent extraterrestrial life form, or for future humans, who may find them. Neither Voyager spacecraft is heading toward any particular star, but Voyager 1 will pass within 1.6 light-years of the star Gliese 445, currently in the constellation Camelopardalis, in about 40,000 years.[1]
Carl Sagan noted that "The spacecraft will be encountered and the record played only if there are advanced space-faring civilizations in interstellar space. But the launching of this 'bottle' into the cosmic 'ocean' says something very hopeful about life on this planet."[2] Thus the record is best seen as a time capsule.

Carl Edward Sagan (/ˈseɪɡən/; November 9, 1934 – December 20, 1996) was an American astronomer, cosmologist, astrophysicist, astrobiologist, author, science popularizer, and science communicator in astronomy and other natural sciences. He is best known for his work as a science popularizer and communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space: the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them

On August 25, 2012, data from Voyager 1 indicated that it had become the first human-made object to enter interstellar space, traveling "further than anyone, or anything, in history".[1] As of 2013, Voyager 1 was moving with a velocity of 17 kilometers per second (11 mi/s) relative to the Sun.[2]
