Skylab What is it ? Time line Background Scientists and Engineers Technologies How it's used in other sectors Skylab was the America's first experimental space station, and it was designed for long durations. It was to prove if humans could live and work in space for long period of time. It was created using various metals, and aluminum. It was made for studying sun, microgravity research, to learn more about the planet earth, and to work as a laboratory in earth orbit. The idea of the skylab was actually came in 1959 by a famous scientist named Wernher Van Braun, but it actually took a few years to establish it and to get its name. But finally in 1970, the orbiting system got it's name by George Low. Skylab 1 was launched into earth orbit by a Saturn V rocket. It was launched on the May 14, 1973 from the NASA'S Kennedy space center. Skylab 1 was unmanned. They returned back on February 8, 1973. Their second mission of skylab 2 was launched on May 25, 1973, using a Saturn 1B vehicle. Their mission lasted for 28 days and they came back on June 22, 1973. Their mission for skylab 3 was launched soon after skylab 2, on July 28, 1973. They used Saturn 1B as their vehicle. They traveled 24.5 miles for 59 days, 11 hours, and nine minutes. Their mission ended on September 25, 1973. The last skylab mission was the skylab 4 and was launched in Saturn 1B, again in 1973, on November 16. They traveled 55.5 million miles, and more than skylab 3. Also they stayed for 84 days, one hour, and 16 minutes. Their journey ended on February 8, 1974. The importance of the syklab missions was to see if humans could in space for long period of time and to know more about solar astronomy beyond terrestrial observations. An important event took place in 1959 when rocket scientist Wernher Von Braun, submitted his final project. The idea behind that project was to get humans on the Moon. When the idea was only for Moon missions, the scientist got an idea for an orbiting laboratory. The idea then was used for the skylab, and to orbit Earth and send information to Earth. The technologies that were used were the X-Ray telescopes, and cameras. They were used to photograph the Sun's activity. They were also used to record data for Earth's meteorology and oceanography from space. The other technologies that were used were the oscillating chairs, and ergometers. They were used to study weight, and it also recorded the effects of long- term exposure to space. Unfortunately there were any Canadians working on this project. But there were a lot of scientists working on this project. So, one of them was the rocket scientist Wernher Van Braun who came up with the skylab idea, and he was the engineer as well. One of the engineer was McDonnell Douglas who was part of the construction of the skylab. Skylab is used in the environment and they had detected micro-organisms. They had also found in-flight bacterial contamination in the first two flights, and in the skylab they found even higher number of in-flight contamination. It's also used in medical form, they have done medical experiments on human, to see the adaptability to zero gravity. Skylab fell down to Earth when it moved into a stable altitude and the systems were shut down. The scientist expected the skylab to stay for atleast 8 to 10 years. But it fell down in 1977. The skylab was 91 metric ton structure and was 36 meters high. It has an diameter of 6.3 meters and flew at an altitude of 435 meters. Interesting Facts!!

I think this website is really useful for because it has a lot of good background information and everyone would have a really great understanding of it. I think this website could be used for everyone as well. Also, this is really good for secondary students and is really great for projects. This website provides a really great history of all the skylabs, and has the structure for the skylab vehicles. I this website is really good for students because it has a lot of general information for the skylab. Also, the level for this website is great for all types of students. This website could be used again for projects This website is suited for teachers and students. This website has almost all of the information for the skylab, including all the problems and the historical background. It's best suited for secondary students, due to the level of this website.
