Transcript of Space Exploration
Voyager 1 is a space probe launched by NASA on September 5, 1977 to study the solar system. Operating for 36 years the spacecraft communicates with the Deep Space Network to receive routine commands and return data. It is the farthest man made object from Earth and was the first probe to provide detailed images of planets and their moons.
Voyager 2 is a space probe
launched by NASA on August
20, 1977. It was actually
launched before Voyager 1,
but Voyager 1 moved faster
and eventually passed it.
Voyager 2 is part of the Voyager program with its identical sister
craft Voyager 1, and is in extended mission, tasked with locating and studying the boundaries of the
Solar System.It is still the only spacecraft to have visited the two outer giant planets Uranus and Neptune
Neil Alden Armstrong was an American astronaut and the first person to walk on the Moon. He was the astronaut to say the famous words " One small step for man, one giant leap for man kind.", as he took the first steps on the moon
Sputnick 1 & 2
Sputnik 1 was the first artificial earth
satellite sent into space. The Soviet Union
launched the satellite into space on October 4,
1957. The satellite traveled at about 18,000 mph, taking about 96 minutes to complete each orbit. Signals continued for 22 days until the transmitter batteries ran out on October 26 ,1957. Sputnik 1 burned up on January 4 ,1958, as it fell from orbit ,reentering Earth's atmosphere, after traveling about 44 million miles and spending 3 months in orbit.
Explorer 1 was the first satellite of the United States, launched as part of its participation in the International Geophysical Year. The mission followed the first two satellites the previous year; the Soviet Union's Sputnik 1 and 2, beginning the Cold War Space Race between the two nations. The spacecraft was launched on January 31, 1958,returning data until its batteries were exhausted after nearly four months. It remained in orbit until 1970.
Sputnik 2 was the 2nd spacecraft launched into orbit on November 3rd, 1957. It carried the first living organism into space, a dog named Laika. Laika was a female part Samoyed terrior originally named Kudryavka ( little curly). Sputnik 2 allowed enough room for her to lie down or stand and was padded. There was no capability of returning a payload safely to Earth at this time, so it was planned that Laika would run out of oxygen after about 10 days of orbiting the Earth. Because of the thermal problems she probably only survived a day or two. The mission provided scientists with the first data on the behavior of a living organism in the space environment.
These 2 orbits created the Cold War Space Race.
Voyager 1 & 2
Luna 1 was the first spacecraft to reach vicinity of the moon. It was launched on January 2, 1959. On January 3, at a distance of 113,000 km from Earth, a large cloud of sodium gas was released by the spacecraft. This glowing orange trail of gas, visible over the Indian Ocean allowed astronomers to track the spacecraft.
Apollo 11 was the spaceflight that landed the first humans on the Moon, Neil Armstrong and Buzz Aldrin, on July 20, 1969. The spacecraft carried astronauts, Neil Armstrong, Buzz Aldrin, and Michael Collins to the moon. Nine years earlier, U.S. President John F. Kennedy had said that by the end of the decade the country would put a man on the moon and return him safely to Earth. President Kennedy's moon mandate came at the height of the space race—and an end to the Cold War between the United States and what was then the Soviet Union.
Edwin Eugene "Buzz" Aldrin, Jr. is a former American astronaut, and the second person to walk on the Moon. He was the lunar module pilot on Apollo 11.
Michael Collins is an American former astronaut and test pilot. His second spaceflight was as the command module pilot for Apollo 11. While he orbited the Moon, Neil Armstrong and Buzz Aldrin made the first manned landing on the lunar surface.
Space exploration has been around since the beginning of time. Whether it's going out into to space or just watching the stars appear. Today, i will be talking about going into space in satellites, probes, and ships. Starting at the beginning.
