  1. Time Line The most important people and events in astronomical history By : Beth Lingerfelt, Esther Newman, And Holly Larkin

  2. Copernicus 1473 • 1473-1543 • Copernicus was born on February 19, 1473 in Torun, Poland. He was a proponent of the theory that the sun and not the earth was the center of the universe. He published a book called De RevolutionibusOrbiumCoelestim (Translated: on the Revolutions of the Heavenly Spheres). His theory was finally proven by Sir Isaac Newton. Coperniucus died on May 24, 1543 in From bork, Poland

  3. Brahe 1546 • 1546-1601 • Tycho Brahe made a star catalogue with over 100 stars, and proved that comets are objects in space, and not the atmosphere. He showed irregularities in the moons orbit and lived by the words “Non VideriSedesse” (not to be seen but to be)

  4. Galileo 1564 • 1564-1609 • Galileo was born on February 15, 1564 in Pisa Italy. In 1609 he learned of the invention of the telescope in Holland, then creating a far superior model he discovered the moons of Jupiter and the phases of Venus. Because of his support in the heliocentric theory he was sentenced to a life time imprisonment and eventually became blind at the age of 72. he died in 1642 – the same year Sir Isaac Newton was born.

  5. Kepler 1571 • 1571-1630 • The German astronomer Johannes Kepler was born on December 27, 1571. he was the discoverer of the three laws of planetary motion and proved that the orbit of Mars was an ellipse. In 1600 Brahe invited Kepler to be his assistant. He died on November 15, 1630.

  6. Edwin Hubble 1889 • He determined the existence of several other galaxies such as our own milky way, which had until then been believed to be the universe. Hubble had also devised a classification system for the various galaxies he observed, sorting them by content, distance, shape, and brightness. From these observations, he was able to formulate Hubble's Law in 1929, helping astronomers determine the age of the universe, and proving that the universe was expanding. In 1917, Albert Einstein produced a model of space, claiming that space was able to expand or contract. Hubble found this assumption so farfetched, that he revised his theory. Einstein visited Hubble to thank him in 1931. 

  7. Sputnik 1957 • Lunched about 51 years ago on October 4, 1957 by Russia. The sputnik was the first artificial satellite a marked the beginning of the space race. It carried a thermometer, two radio transmitters, and circled the earth once every 96.2 minutes. After 57 days in orbit it was destroyed re-entering the atmosphere

  8. Mercury the Mission 1961 • 1961-1963 • Project Mercury was America's first human space flight program. The goal was to launch a man into Earth’s orbit and bring him back safely. Seven Military pilots were chosen for the program, and six made space flights between 1961 and the conclusion of the program in 1963

  9. Shuttle Missions 1961 They began planning for space missions in 1961 when President Kennedy wanted to land a man on the moon. The first successful shuttle was Apollo (see “Apollo” slide)which launched December of 1968. The Apollo missions continued through the years and led to more missions being launched. There has been many other successful shuttle missions, over 100! The most recent shuttle mission launch was March 15, 2009. It was mission STS-119 and it landed back on Earth March 28, 2009.

  10. Gemini 1964 All Shuttles were launched from Cape Canaveral, Florida Accomplishments: • Rendezvoused and docked with a second orbiting vehicle, From ‘Gemini’ scientist learned how to keep astronauts in space for up to two weeks, developed and tested controlled re-entry into Earths atmosphere, enabled astronauts to leave the space craft while in space – just to name a few.

  11. Apollo 1968 • Apollo – December 24, 1968, was the first artificial satellite to orbit something else other than the earth. It made a complete orbit around the Moon 10 times in 20 hours. • Apollo 11 – July 16, 1969, Apollo 11 space craft was launched from the Kennedy space Center at 9:32 am. It was the very first lunar landing mission where the famous words “one small step for man, one giant leap for mankind” were spoken on the Moon’s surface.

  12. Hubble telescope 1990 • The Hubble space telescope revealed the age of the universe to be 13 to 14 billion years old. It played a key role in the discovery of dark matter. More than 6000 space articles have been published based on the telescope’s findings. Every 97 minutes it completely revolves around earth.

  13. Mar’s Rovers 2003 • 2003 – today • Sprit and Opportunity are the only rover’s on Mars and their goal is to search for and characterize a wide range of rocks and soils that could hold clues too past life and water activity. The Mars Rovers recently logged a memorable March, with Spirit finally making some serious tracks and setting a new driving record for a five-wheeled rover, after loosing his front wheel in March 2006 and Opportunity getting a first glimpse on the distant horizon of its next big attraction, Endeavour Crater which is estimated to reach it in one Martin year (about 23 months).
