Transcript of Explorer 1

The Explorer 1 was launched out
into space in 1958 to measure the
radiation environment in the Earths
orbit, it discovered the Van Allen
radiation belts. Explorer 1 September, 7th ,1914: Dr.James Van Allen (the man who discovered the Van Allen radiation belts) was born.
1957-1958: Dr. James Van Allen and his associates built parts of the Explorer 1.
January, 31st, 1958: The Explorer 1 was launched by the United States.
May, 23rd, 1958: The Explorer 1 made it's final transmission when it's battery ran out.
1959: Explorer 6 was sent out to space in hopes it would be as successful as Explorer 1. Explorer 6 took the first pictures of Earth from an orbit.
March, 31st, 1970: Came crashing down to Earth over the Pacific ocean.
August, 9th, 2006: Dr. James Van Allen passed away.
The launch and crash of Explorer 1 will be further explained in slide 6. Timeline Driving Factor that led to Explorer 1 Significance of Explorer 1
After Explorer 1 stopped transmitting because the batteries ran out it stayed on orbit for years. In 1970 it came crashing down to Earth over the Pacific ocean. Dr. James Van Allen was an American scientist who discovered the Van Allen radiation belts. He had a theory that there was very strong radiation coming from a belt which had charged particles trapped space due to the Earth's magnetic field. Two months later the existence of these belts were confirmed by a U.S. satellite and
named after Dr. James Van Allen. Dr. James Van Allen Nasa JPL Explorer 1 was the first sattellite launched by the United States.
The satellite was 203 centimeters long and 15.9 centimeters in diameter.
It weighed 14 kilograms (30.8 pounds). Bibliography "NASA - National Aeronautics and Space Administration."

Launch of the Explorer 1 Explorer 1 was launched out into space on January, 31st, 1959. It was the first satellite ever launched by the United States. Explorer 1 was made
by Nasa/J.P.L. along
with many other space robots/technology. Nasa is a website and a huge organization dedicated to space research. "NASA - National Aeronautics and Space Administration." NASA. N.p., n.d. Web. 01 Oct. 2012. <http://www.nasa.gov/>. It is important that we discovered these belts because they are what protect us from Solar radiation. When radiation from the Sun reached the earth the belts act as a shield and send the radiation the the poles, at the poles that material combines with the material in the air there and creates the Northern and Southern Lights. There was not much controversy they just wanted to know about the radiation environment in the Earth's orbit. Although when Dr. James Van Allen had his theory about the Van Allen radiation belts, not everyone agreed with him until the existence of these belts were confirmed later. Scientists wondered about the radiation environment in the Earth's atmosphere. That was Explorer 1's main goal, the measure the radiation environment in the Earth's orbit. In doing so the Explorer 1 discovered the Van Allen radiation belts. "Northern Lights vs. Southern Lights." Image of the Day. N.p., n.d.

Explorer 1's technology isn't really used in other sectors (medicine, transport or environment) but without the discovery of the Van Allen radiation belts we wouldn't know why the Northern and Southern lights happen, or how the Earth protects itself from the Sun's harmful rays.

This article provided lot's of information about the Explorer 1 and how it discovered the Van Allen radiation belts. The information was accurate, reliable and non-biased information. Over all it was a very useful and helpful article. Annoted Bibliography
