I invite everyone to celebrate Earth Day today. Observing our home is at the core of NASA’s mission, and it continues be a dynamic and growing area of our activity.
Living in space is going to be part of our future, but what we know about Earth and how we live on this planet is absolutely critical. That’s one reason I was so pleased that this past year NASA launched five Earth new observation missions, including sending instruments to the International Space Station that are adding to its capabilities as a platform for Earth science in addition to what it helps us learn about human health in space.
We want to know how our planet works, how we affect it, and how it might change in the future. Right now, including those recent launches, NASA has 20 spacecraft orbiting Earth and gathering amazing science data. They can see carbon dioxide in the air, water reserves below ground, the heat our planet is absorbing, and the inside of hurricanes — Amazing stuff!
This is the first time in human history that we can really see and hope to understand how a planet lives and breathes. It’s a tall order, but NASA is on it. With this knowledge we are able to tackle one of the biggest challenges facing everyone on Earth today: Climate Change. Because we have these incredible tools in space, we can now see the changes across the whole planet. We can see the facts.
We don’t have all the answers yet, but we’re making progress. We are steadily increasing the known, and decreasing the unknown about how Earth is changing. Knowledge is a powerful tool, and with it we can all be better stewards of our home planet.
This Earth Day all of you have the opportunity to become Earth observers. We want everyone to stop for a moment this April 22 and share their photos and videos of favorite places they’ve been using the hashtag #NoPlaceLikeHome.
We’ll be posting NASA’s best shots from space (including some of my favorites from my “old days” in shuttle) to send the message that there really is no place like our home planet. We all love Earth, so let’s be more observant of it. Let’s learn more about it and NASA will keep circling the globe to help us all protect it and work toward a brighter future.
