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 dreamed of going to outer space? When Sally Ride was a little girl, she watched on TV as astronaut John Glenn launched into space. Twenty years later, she became the first American woman to go to space. Ride had loved science since she was young. Some of her teachers thought she was wasting her time studying science, but she went on to earn her PhD in astrophysics anyway. When NASA's astronaut training program opened to women, Ride quickly applied. Some people thought women couldn't handle space flight. But Ride worked hard and proved them all wrong.

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?

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.

Meg Lowman was always fascinated by the natural world above her head—the colors, the branches, and, most of all, the leaves and mysterious organisms living there. Meg set out to climb up and investigate the rain forest tree canopies—and to be the first scientist to do so. But she encountered challenge after challenge. Male teachers would not let her into their classrooms, the high canopy was difficult to get to, and worst of all, people were logging and clearing the forests. Meg never gave up or gave in.
