Facts about astronaut Neil Armstrong

Facts about Astronaut Neil Armstrong

1. It is said that his passion for flying began when he was just two years old when he was taken by his father to the National Air Races, which was held in Cleveland, Ohio. 
2. This interest deep
ened further when ate age six he experienced his first ride on an airplane in a Ford Tri-Motor, in Warren, Ohio.
3. Neil Armstrong started taking lessons in flying at an airport located to the north of Wapakoneta when he was 15 years old in an Aeronca Champion airplane. In order to pay for the lessons, he worked at a number of jobs at the airport as well as the town.
4. It was on his 16th birthday that Armstrong became a licensed pilot, which he got before he had graduated and before he had even received his automobile driver's license.
5. While he was studying for his aeronautical engineering, the Korean War broke out, in 1950, in which he served, flying 78 combat missions. His plane was shot down once and he was also awarded 3 Air Medals.
6. Later, he became a skillful test pilot, flying right to the atmosphere's edge, 207,500 feet, or 63,198 meters, at 4,000 miles per hour, in the famous experimental rocket powered aircraft, X-15.
7. Neil Armstrong went on his first mission into space on the 16th of March 1966, in the spacecraft Gemini 8, as the command pilot. He docked the Gemini 8 successfully with an Agena target craft that was in orbit already. Although the docking was smooth enough, while the spacecraft orbited together, they started to roll and pitch.
8. Armstrong grew up in Ohio with a strong interest in flight and earned his pilot's license while still a boy.
9. After flying combat missions during the Korean War, he became a test pilot and joined NASA's astronaut program in 1962.
10. As he stepped on the moon's dusty surface, Armstrong said: ""That's one small step for a man, one giant leap for mankind."
11. Asked about his experience on the moon, he told CBS: "It's an interesting place to be. I recommend it."
12. A crater on the moon is named for Armstrong. It is located about 30 miles from the site of the landing.
13. Armstrong took a NASA desk job after the Apollo 11 mission, becoming the deputy associate administrator for aeronautics in the office of advanced research and technology.
14. A year later he became a professor of engineering at the University of Cincinnati.
15. In 2005, Armstrong was upset to learn that his barber had sold clippings of his hair to a collector for $3,000.
16. The man who bought the hair refused to return it, saying he was adding it to his collection of locks from Abraham Lincoln, Napoleon, Marilyn Monroe, Albert Einstein and others.
17. Despite his taciturn nature, Armstrong once appeared in a television commercial for the U.S. automaker Chrysler. He said he made the ad because of Chrysler's engineering history and his desire to help the company out of financial troubles.

Unknown Facts about Sun



1. The Sun is a star that is in the center of the Solar System

2. The Sun is recognized as having the largest mass in our Solar System.

3. The diameter of the Sun is 1.4 million km (870,000 miles)

4. The Sun’s distance from the Earth is 150 million km (93 million miles)

5. Earth orbits the Sun 365 days, yes, one year.

6. The Sun rotates every 25-36 earth days.

7. The Sun’s energy travels outwards.

8. The Sun’s core is composed of hot & dense gasses. It has a temperature of 15 million Kelvin (27 million degrees F)

9. The Sun is made up of 92% hydrogen, 7% helium and the remainder of various gasses.

10. The atmosphere of the Sun is composed of three areas: the photosphere, chromosphere, and solar corona.

11. The corona is the Sun’s outer atmosphere with temperatures that can go from a few thousand kelvins to a few
million kelvins.

12. Helmet streamers are big white regions that extend out from the Sun in which solar plasma are trapped by the magnetic field of the Sun.

13. Solar flares from the Sun are sudden bursts of brightness that happen in places near the sunspots.

14. Sunspots appear on the surface of the Sun and look dark because of the lower temperatures near it.

15. The internal structure of the Sun is composed of: the inner core, radiative, core, and the radiative core.

16. The inner core is the hottest part of the Sun, and can reach 27 billion F.

17. A solar eclipse occurs when Earth passes the shadow of the Moon.

18. A total solar eclipse occurs only during a new moon, which is when the moon sits directly between the Earth and the Sun.

19. Radiations of the Sun are in two forms, electromagnetic (photons) and particle (electrons, protons, alpha particles, etc.) radiation.

20. In February 1974, Skylab was the first manned spacecraft to study the Sun.

21. Solar flares occur when magnetic fields of the Sun come together and cause huge explosions on the Sun’s surface.

22. Solar flares produce bursts of electromagnetic radiation, x-rays, ultraviolet radiation, visible light, and radio waves.

23. Johann Rudolf Wolf, in 1848 developed a method to count sunspots which has been called Wolf number.

24. Most ancient civilizations have based their culture on the presence of the Sun. These include the myths as developed by the following people: Egyptians (Re or Ra), Aztecs (Tonatiuh and Huitzilopochtli), Greek (Helios), Inca (Inti), and the list goes on.

25. If you weigh 100 lbs, your weight on the Sun would be 2707 lbs. (multiply your actual weight by 27)
