Sally Ride soared into outer space on the Space Shuttle Challenger in 1983, the youngest astronaut and the first U.S. woman in space. Just 32 years old that year, this California girl was already an accomplished astrophysicist when NASA chose her. Since then, she has written several books introducing young readers to the subject of space exploration and encouraging them to study the sciences.

In this title, examine the life of imaginative space traveler and medical innovator Mae Jemison. Readers will enjoy digging into Jemison's personal story, beginning with her childhood in Chicago where she watched Star Trek and conducted dozens of her own science experiments. Students can trace Jemison's success, from her education at Stanford University and Cornell University to her years volunteering with the Peace Corps, before her acceptance into the NASA space program and flight into space on the Endeavour. Engaging text and photos offer insight on topics such as astronomy, gravity, and biomedical engineering. While a timeline, glossary, and index supplement the text, an entertaining science activity allows readers their own hands-on experience based on the science that inspired this woman's groundbreaking career. Checkerboard Library is an imprint of ABDO Publishing Company.
This book describes the work of the National Aeronautics and Space Administration (NASA).

Ancient astronomers looked at movements in the sun, moon, and stars to guide travelers and keep track of the seasons. Nicholas Copernicus was the first to challenge people's beliefs that Earth was the center of the solar system and is known as the founder of astronomy. Galileo Galilei built a telescope and spotted craters on the moon and sunspots on the sun. Isaac Newton invented the reflecting telescope and discovered the law of gravity. Astronomers continue to work every day to uncover the mysteries of the universe.
Long ago, astronomers believed that the Earth was the center of the universe. But now we know that it is only a tiny part of the universe and that our solar system is just a tiny part of our galaxy. In 1957, space travel began. Work done in space has helped us in the areas of medicine, computer science, and the environment. The International Space Station, a lab floating in space, is where astronauts do experiments that help us on Earth. The next manned trip to the moon is planned for 2018.
Much of what we know today about Earth is from images taken by cameras on powerful telescopes. Edwin Hubble changed our view of the universe. Working in an observatory, he found that there are other galaxies besides the Milky Way. He also showed that the universe is still growing. Lyman Spitzer, Jr. proposed placing telescopes in space, and in 1990, the Hubble Space Telescope was launched. It sends us amazing images of the universe.
