On July 20, 1969, 530 million people around the world were glued to their TVs. They watched live as astronauts Buzz Aldrin (pictured above) and Neil Armstrong became the first people to walk on the moon.
Now, 50 years later, the U.S. space agency, NASA, is preparing for a return trip. It’s designing a spaceship that will orbit, or travel around, the moon. The ship, called the Gateway, will be a home base from which astronauts can make short trips to the moon’s surface.
Returning to the moon will help NASA prepare for human space travel to faraway planets, like Mars. “We’re not just landing on the moon and coming home, we’re going to stay,” says Marshall Smith, who manages the Gateway project at NASA. “It’s tremendously exciting.”
