For more than 60 years, NASA has been breaking barriers to achieve the seemingly impossible—from walking on the Moon to pushing the boundaries of human spaceflight farther than ever before. We work in space and around the world in laboratories and wind tunnels, on airfields and in control rooms to explore some of life’s fundamental mysteries: What’s out there in space? How do we get there? And what can we learn that will make life better here on Earth? We are passionate professionals united by a common purpose: to pioneer the future in space exploration, scientific discovery and aeronautics research. Today, we continue NASA’s legacy of excellence and innovation through an unprecedented array of missions. We are developing the most advanced rockets and spacecraft ever designed, studying the Earth for answers to critical challenges facing our planet, improving the air transportation experience, and so much more. Join us as we reach for new heights and reveal the unknown for the benefit of humanity.

European Southern Observatory
ESO, the European Southern Observatory, is the foremost intergovernmental astronomy organisation in Europe and the world's most productive astronomical observatory. ESO provides state-of-the-art research facilities to astronomers and is supported by 16 member-states along with the host state of Chile and with Australia as a Strategic Partner. ESO's main mission, laid down in the 1962 Convention, is to provide state-of-the-art research facilities to astronomers and astrophysicists, allowing them to conduct front-line science in the best conditions. By building and operating a suite of the world's most powerful ground-based astronomical telescopes enabling important scientific discoveries, ESO offers numerous possibilities for technology spin-off and transfer, together with high technology contract opportunities and is a dramatic showcase for European industry. Whilst the Headquarters (comprising the scientific, technical and administrative centre of the organisation) are located in Garching near Munich, Germany, ESO operates, in addition to the Santiago Centre, three unique observing sites in Chile: La Silla, Paranal and Chajnantor.
