What is out there? • Ever since mankind has looked up at the moon and stars, we have wandered about life in the universe.
Chuck Yeager of WV • Chuck Yeager was born and raised in WV. • In 1947, Chuck Yeager drove the first plane to break the sound barrier. • US was ahead of the world in the space race. • But then………
Space Race Begins • October 4, 1957 – Soviet Union launches Sputnik I • The world's first artificial satellite • Size of a basketball • Weighed only 183 pounds • Took about 98 minutes to orbit the Earth on its elliptical path. While the Sputnik launch was a single event, it marked the start of the space age and the U.S.-U.S.S.R space race.
Vanguard • The US thought they would be the first to successfully launch a satellite into space. • They put together a scientific team and began working on Vanguard.
US vs Russia • As a technical achievement, Sputnik caught the world's attention and the American public off-guard. • Its size was more impressive than Vanguard's intended 3.5-pound payload. • The public feared that the Soviets' ability to launch satellites also translated into the capability to launch ballistic missiles that could carry nuclear weapons from Europe to the U.S. • Then the Soviets struck again; on November 3, Sputnik II was launched, carrying a much heavier payload, including a dog named Laika.
Explorer 1 • Explorer project – 4 months after Sputnik US sent Explorer 1 into space.
Mariner Project • The Mariner Project was a series of US space probes build to provide information on the inner planets – Mercury, Venus, and Mars. • Mariner 2 launched in 1962. • There were many embarrassing disasters on the launch pad at Cape Canaveral. Mariner I failed on launch pad.
Voyager • The Mariner Project was renamed Voyager. • Voyager 1 launched from Kennedy Space Center September 1977 and approached Saturn in 1980. • Voyager 2 launched from Cape Canaveral in 1977 also.
Space Probes (Satellites) • Mariner • Viking 1 and 2 (summer 1976) 1st successful landing on mars. Designed to explore inner planets • Voyager 1 and 2 designed to explore outer planets • Galileo – 1989 – The 1st probe to orbit Jupiter and sent a smaller probe into it’s atmosphere. Launched from a space shuttle.
Mercury Program The Mercury Program (1960 – 1962) 1st program to put an astronaut into space.
Mercury-Redstone 3FREEDOM 7May 5, 1961Alan B. Shepard, Jr. 15 minutes, 28 secondsSuborbital flight that successfully put the first American in space.
Gemini Program • Was a manned space program to put 2 men into space – hence the name Gemini which means twin.
The Apollo Program • Project Apollo was a series of human spaceflight missions undertaken by NASA, on behalf of the United States of America. • The program used the Apollo spacecraft and Saturn launch vehicle, and was conducted during the years 1961 – 1975. • It was devoted to the goal (in U.S. PresidentJohn F. Kennedy's famous words) of "landing a man on the Moon and returning him safely to the Earth" within the decade of the 1960s. • This goal was achieved with the Apollo 11 mission in July 1969.
The US Space Shuttle • The US space shuttle was designed to be launched into space by rockets and then to return to the Earth’s surface by gliding down and landing on a runway. It was first used in the 1980’s. • It is the first reusable spacecraft.
Shuttle Missions • Columbia, Challenger, Discovery and Atlantis. • Challenger was destroyed on launch in 1986 • Endeavour was built as a replacement. • Columbia was destroyed on re-entry in 2003.
The International Space Station • A joint effort between 5 space agencies. • The agencies include the US, Russia, Japan, Canada, and Europe. • It orbits in low earth orbit. • The station has continuous people staying since it was first occupied in 2000.
