Showing results for "Discovery" in Astronomy & Space

On July 20, 1969, Neil Armstrong took one giant leap for mankind when he became the first person to set foot on the moon. Now, listeners can step back in time to learn about what led up to the Apollo 11 moon landing, how the historic event unfolded, and the ways in which one remarkable day changed America forever.

This exciting second book in the Lost series tells the incredible true story of the doomed Apollo 13 moon mission that nearly ended in disaster. On April 11, 1970, the Apollo 13 space shuttle set off for the third intended American moon landing. Two days later and 200,000 miles from Earth, disaster struck when an oxygen tank exploded onboard the spacecraft, leaving three astronauts with only one goal: to make it home alive.

Edwin Hubble’s discovery of the Big Bang is one of the most important in astronomy and physics. It taught us where the universe came from and how it might end. Students will learn how Hubble’s early, unprecedented photographs of pulsars served as one of the first clues along the path that led him to the discovery of the Big Bang. Listeners will also discover how Hubble’s discovery opened up new doors to information about the universe.

Have you ever dreamed of walking on Mars? Or maybe even living there? Ever since Mars was discovered, people have wondered if there could be life on this mysterious red planet. For years, astronomers at NASA and other space agencies have been exploring Mars. They've sent rovers to study the planet and search for water and signs of life. One day, NASA plans to send astronauts there, too. But first, they need to learn many things about Mars and how people might travel that deep into space.

Did you know that astronauts work on Earth and in space to study places beyond our planet's atmosphere? But there's a lot more to space travel than just research. With no gravity, a wild schedule that includes 16 sunrises and 16 sunsets every 24 hours, and no fresh food, it can be a challenge to stay healthy in orbit. Public and private space agencies are working to solve these problems as humans travel farther and more frequently into the depths of space. Learn more about the daily lives of astronauts and how they live, work, and prepare for the future in space.

Did you know that companies and governments send more than 100 satellites into space every year? And that most of those satellites continue to orbit Earth - even after they have stopped working? More than 500,000 old satellites, pieces of metal, and other bits of junk currently pollute Earth's orbit. And that number is growing. Astronomers, engineers, and politicians all agree that the future of space exploration is in danger if this debris isn't taken care of. But the problem of garbage in space is difficult and expensive to solve.

Have you ever wondered what it would be like to go into outer space? Soon you might be able to find out! For years, only trained astronauts were allowed to travel through space, but now lots of companies are creating spacecraft that will allow regular people to experience space for themselves. World View Enterprises wants to take people to near space using a helium balloon. And Virgin Galactic has already sold hundreds of tickets for a ride on its Unity spacecraft. But is this kind of space travel safe? Will these new spacecraft be able to get off the ground?

On January 31, 1961, a three-year-old chimpanzee named Ham made history. Strapped inside a Mercury capsule, the little chimp blasted off into the sky, becoming the first intelligent being to ride an American rocket into suborbital space. Ham made a vital contribution to the United States space program. Because there were so many unanswered questions about space travel, scientists could not risk sending humans on a journey into the unknown. Chimpanzees, however, are very similar to humans in the makeup of their skeletons and internal organs.
