NASA programs encompass a wide range of initiatives aimed at exploring space, conducting scientific research, and developing new technologies. Key programs include the Artemis program, which aims to return humans to the Moon, and the Mars Exploration Program, focused on studying the Red Planet through rovers and orbiters. Additionally, NASA conducts Earth science missions to monitor climate change and natural disasters. The International Space Station (ISS) serves as a platform for research in microgravity, while programs like Hubble Space Telescope and James Webb Space Telescope enhance our understanding of the universe through advanced astronomical observations.
