- Gemini Program (1964-1966): Focused on developing techniques for rendezvous and docking in space, paving the way for the Apollo program.
- Apollo Program (1961-1972): The iconic program that landed the first humans on the Moon in 1969.
- Space Shuttle Program (1981-2011): A reusable spacecraft that launched satellites, conducted scientific research, and transported astronauts to and from the International Space Station (ISS).
- International Space Station (ISS): A joint project with international partners, the ISS is a habitable space station in low Earth orbit, serving as a platform for scientific research and long-duration human spaceflight.
- Commercial Crew Program: A program to develop and certify commercial spacecraft for human spaceflight to and from the ISS.
Space Exploration:
- Voyager Program (1977-present): Two spacecraft that have explored the outer Solar System, sending back groundbreaking data about Jupiter, Saturn, Uranus, and Neptune.
- Mars Exploration Program: A series of robotic missions to Mars, including rovers like Curiosity and Perseverance, studying the planet’s geology, Climate, and potential for past or present life.
- James Webb Space Telescope (JWST): A powerful infrared telescope launched in 2021, designed to observe the first stars and galaxies, study exoplanets, and investigate the evolution of the universe.
Aeronautics Research:
- X-Planes: A series of experimental aircraft that have pushed the boundaries of flight, leading to advancements in supersonic flight, hypersonic flight, and other areas.
- NASA Langley Research Center: A leading center for aeronautics research, developing technologies for safer, more efficient, and environmentally friendly aircraft.
