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.

Ancient life in Greenland and the search for life on Mars

Scientists say they've found fossils showing life existed on Earth 3.7 billion years ago. How good is the evidence? And what does it mean for the search for life elsewhere in our solar system?

Why the Deep Space Atomic Clock is key for future space exploration

Measuring time is a crucial part of navigation – particularly in space, where exacting precision is called for. The DSAC is poised to make a change that will aid future deep space missions.

Data error discovery slows trend of growing Antarctic sea ice

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…
