SALLY RIDE, HERO
Sally Ride was the first American woman and third woman to go to space. Sally Ride was born in 1951 in California. At a young age she was interested in both science and tennis, but she decided to go into a scientific profession. After receiving her Ph.d. at Stanford University, she joined NASA. On June 18, 1983, she became the first American woman to go into space. After she stopped working for NASA in 1987, she started teaching at The University of California in San Diego. She also encouraged other girls to pursue their dreams in science and mathematics. She was added to the Astronaut Hall of Fame in 2003. Sadly after all the work she had accomplished, she died at the age of 61 of pancreatic cancer in 2012. For some people, she was just the first woman to go to space, but for me she is a hero. She was smart and talented and had many hobbies. She was incredibly successful in her life. She will always remain an important part of science.

Lord of the Rings
Saturn is the sixth planet in the solar system. Almost all gas planets have rings around them made out of chunks of ice and rock, Saturn is no different, because of its beautiful rings, it is called the ‘jewel of the solar system’. Also, Saturn is like Jupiter because they both are giant gas planets made of hydrogen and helium. Saturn is so big that 700 Earths could fit inside it!
Some people think Saturn has one large ring and others think that there are seven large rings around it. From far away it looks like seven, but we now know that in the large rings there are smaller, thinner ringlets. In fact, NASA says that if you were to drive a car across Saturn's rings, it would take longer than a week.
Saturn takes 29 years to go around our sun, whereas the earth takes one year to orbit the sun. In Saturn's 29 year orbit, due to the way it's tilted, viewed from Earth there are two times (approximately every 14 to 15 years) that the rings seem to disappear. However this is only an illusion, because while Saturn is orbiting the sun it gets tilted like a flat piece of paper in front of our eyes. With the sun’s reflection it makes the rings seem to vanish.
Saturn has moons like most of the other planets, but the moons around Saturn each tell a story about its system. Scientists have discovered 53 moons sofar, with another 9 moons possible. That would make 62 moons around Saturn.

Enceladus is the sixth largest satellite of Saturn. It was discovered by William HERSCHEL in 1789 . It is so small (much more than you think) that it can fit within the borders of Arizona, being only 157 miles (252 kilometers) in mean radius. The most exciting part is that this small satellite has water under its surface!! Although it has a cold temperature, it has liquid water that can make possible the chemical reactions which can create life. This liquid includes organic compounds, volatile gases, carbon dioxide, carbon monoxide, salts and silica.
Enceladus has underground oceans, and the surface of this moon has cracks. Following these cracks, underground oceans get through creating a stream all along the surface of the moon. With the cold temperature these freeze and make it look like tiger stripes made from ice. From the tiger stripes, ice particles form a cloud which feeds one of the Saturn's rings.

5 INTERESTING FACTS ABOUT SPACE
1- Venus is the second planet from the Sun and is the second brightest object in the night sky after the Moon.
2- The Apollo astronauts' footprints on the moon will probably stay there for at least 100 million years. Since the moon doesn't have an atmosphere, there's no wind or water to erode or wash away the Apollo astronauts' mark on the moon. That means their footprints, roverprints, spaceship prints, and discarded materials will stay preserved on the moon for a very long time.
3- Sally Kristen Ride said to her family that she went to bungee jumping but she went to space her family learned from radio.
4-Soviet cosmonaut Svetlana Savitskaya became first woman in space in July,25th 1984.
5-Professor Feryal Özel, the only Turkish woman scientist at NASA, is already managing a project for an event horizon telescope that aims to monitor a black hole
