NASA’s vision: To reach for new heights and reveal the unknown so that what we do and learn will benefit all humankind.
To do that, thousands of people have been working around the world – and off of it – for 50 years, trying to answer some basic questions. What’s out there in space? How do we get there? What will we find? What can we learn there, or learn just by trying to get there, that will make life better here on Earth?
NASA conducts its work in three principal organisations, called mission directorates:
Aeronautics: pioneers and proves new flight technologies that improve our ability to explore and which have practical applications on Earth.
Human Exploration and Operations: focuses on International Space Station operations and human exploration beyond low Earth orbit.
Science: explores the Earth, solar system and universe beyond; charts the best route of discovery; and reaps the benefits of Earth and space exploration for society.

Higher CO2 levels in the atmosphere are changing how quickly trees process water, which scientists are studying to see if it will affect river flow, flooding and soil moisture.
Climate change is affecting all regions of the globe. But some places, such as Africa, are more vulnerable than others.
The amount of the earth’s ocean surface covered by sea ice has been continually observed by satellites and its extent estimated since 1978. The trend has been for shrinking sea ice in the Arctic and, more…
It’s been nearly 30 years since the discovery of the ozone hole over Antarctica, and the realisation that chlorine, in the form of chlorofluorocarbons or CFCs, was the chemical culprit behind the depletion…
Earthquake lights are among nature’s most strange, most ephemeral, and hard-to-explain phenomena. While rare, and only recently accepted by science, they have been reported for hundreds or even thousands…
Satellite and in situ observations show sea level is continuing to rise. In the last Intergovernmental Panel on Climate Change report, earth system model projections indicated global sea-level rise by…
NASA is currently poring over more than 6,000 applications for the next intake in its astronaut program - from which nine to 15 candidates will be successful. And while the Space Shuttle program is a thing…
