Our Planet, Our Home┃ An Earth Day Perspective

The third rock. The blue marble. Earth. Home. Every person, place, or thing we know. Everything we do. Every memory we make. It's here, on this pale blue dot. It's just one rocky planet, in one solar system, in one galaxy, among billions. Even as we explore space, we study our home planet. We see it like no one else. An expansive ecosystem. The vegetation. The air. The water. The ice. Our data improves the way we grow food, and how we manage the land we cultivate. NASA has over 20 satellites, measuring the height of oceans and inland waters, clouds and precipitation, carbon dioxide, and much more. For decades, our data has tracked how all these Earth systems interact. From above, we see the connections. Cities transition into farmlands. Tributaries flow into rivers into the sea. Winds move clouds around the planet. Beyond these observations, NASA's ability to model and anticipate how the planet is changing helps communities around the world prepare. We see our changing planet. Hurricanes, volcanoes, fires. And we see the impacts of humans. Melting ice. Rising temperatures. Earth's climate has changed, and is still changing. Our data gives us the understanding to adapt. And to protect our home planet in new ways. Our electric flight technologies will reduce fuel and save energy. We will make cleaner air travel possible. By understanding our changing world, we improve lives and safeguard our future. The future of our little rock in the universe. Our Earth. Our home.
