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 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.

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.

Humans have always been fascinated by the universe, but only a few have been daring enough to travel beyond the Earth.

On April 11, 1970, astronauts Jim Lovell, Fred Haise, and Jack Swigert were launched into space as the crew of Apollo 13. Their mission, like the missions of Apollo 11 and Apollo 12, was to explore the lunar surface. But that mission was never completed. As they began the procedure for landing on the Moon, the spacecraft was rocked by a violent explosion. Oxygen began pouring out of the Service Module, and the spacecraft began to lose power. Jim Lovell radioed Mission Control with the now-famous words, "Houston, we have a problem."

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.

John Farrell takes kids on a rhyming tour of the night sky, from A to Z, with facts about the wonders of space. From distant Andromeda, a galaxy made up of billions of stars, to the constellation of the zodiac, Farrell covers the high points of outer space. How do you find Jupiter or Venus? How does the Moon cause the tides of Earth's shores? How can you find the North Star, and why do all other stars seem to go around it?

Black holes are the most extraordinary phenomenon in the universe, but they are a riddle that confounds our intuitions. Anything that enters them can never escape and yet they contain nothing at all. They are bigger on the inside than the outside suggests. They are dark on the outside but not on the inside. They invert time into space and space into time.
