Have you ever wondered about what lies beyond the sky? The National Aeronautics and Space Administration (NASA) has been trying to uncover the mysteries of the universe since its formation in 1958. In the 1960s, NASA launched the Apollo program aiming to land humans on the Moon. This resulted in Neil Armstrong's famous 'one small step for man, one giant leap for mankind' in 1969. Today, NASA is exploring Mars with its Perseverance rover, searching for signs of ancient life. But how do these spacecrafts travel such vast distances? The answer lies in rocket science. Rockets work on a principle called Newton's third law: for every action, there's an equal and opposite reaction. In the future, NASA plans to return humans to the Moon through the Artemis program and eventually reach the ultimate frontier - Mars! Scientists and astronauts at NASA continue to push the boundaries of our knowledge, proving that the sky is not the limit!
