Our magnificent planet is always ready for its close-up. On Earth Day, April 22, NASA wants to see your take.

NASA invites you to celebrate the planet we call home with our #PictureEarth social media event. Post a close-up photo on social media of your favorite natural features, such as crashing waves, ancient trees, blooming flowers or stunning sunsets. Use the hashtag #PictureEarth and upload the photo on April 22. Be sure to include the location where the photo was taken in the text of your social media post.

On Earth Day, we will share some of NASA's most stunning images of Earth from space to inspire you. We'll check Instagram, Twitter and our NASA Earth Facebook event page to find your images and select photos from around the world to showcase later in videos and composite images.

NASA satellite and airborne instruments picture Earth every day to increase our knowledge of our home and improve lives. These images, shared with scientists and the public worldwide, may use visible light, like a photographer's camera, or peer into infrared, microwave and radio wavelengths that are invisible to human eyes.

Scientists use data from all of our instruments, and from Earth-observing spacecraft from other nations, to build a picture of the planet that grows more and more complete over time.

On April 26, our next addition to our Earth-observing fleet, the Orbiting Carbon Observatory 3, is set to launch to the International Space Station. The new knowledge made possible by this fleet helps create solutions to important global issues such as changing freshwater availability, food security and human health.

DLR and the UStuttgart test transmission of EO data using laser communications
Bonn, Germany (SPX) Apr 08, 2019
Earth observation satellites play a key role in weather forecasting, climate research, monitoring of the planet's surface and the detection of forest fires. These tasks require satellites to transmit very large amounts of data to the ground for analysis. Today's radio systems are reaching their limits in this area. Optical transmission methods, however, offer the possibility of sending data at significantly higher rates. The first transmission tests have now been carried out using the Optical Spac ... read more
