Featured Missions
Our mission milestones showcase the breadth and depth of NASA science.

Lucy
The Lucy mission captured stunning, detailed images of asteroid Donaldjohanson during a fly by on April 20, 2025, as the spacecraft heads towards the distant Trojan asteroids.

NEO Surveyor
NEO Surveyor is expected to launch no earlier than September 2027. It is the first space telescope specifically designed to hunt asteroids and comets that may be potential hazards to Earth.

PACE
PACE is celebrating one year in orbit, tracking ocean health, air quality, and climate. Its data is helping us understand how carbon moves between the ocean and atmosphere.

How Do We Do Research in Zero Gravity? We Asked a NASA Expert
When it comes to experiments in space, astronauts on the International Space Station face challenges you won’t find on Earth: bubbles don’t rise, things float away and many Earth-based lab tools don’t always work the same way. So science in space needs to me reimagined from the ground up. A NASA scientist explains how we study life, chemistry and physics in orbit.

How we Look at Earth
Explore our changing planet
Earth is our home, shared with millions of species. Rapid changes like rising temperatures and more frequent extreme weather are transforming our planet. For over 50 years, observations from space and ground have monitored these changes, guiding critical decisions in areas like agriculture and air quality. By understanding how our actions affect Earth's systems, we can help mitigate these impacts. Discover more about how you can make a difference in safeguarding our planet.
