On April 11, NASA released the first images from the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite, which was launched on Feb. 8, 2024, from Cape Canaveral Space Force Station in Florida. PACE joined the Surface Water and Ocean Topography (SWOT) satellite and Sentinel-6 Michael Freilich in helping NASA revolutionize our understanding of our oceans. You can see one of the images below, in which bright pink and green colors indicate different communities of phytoplankton.<\/p>\n

<\/figure>\nNASA\u2019s PACE satellite\u2019s Ocean Color Instrument (OCI) detects light across a hyperspectral range, which gives scientists new information to differentiate communities of phytoplankton \u2013 a unique ability of NASA\u2019s newest Earth-observing satellite. This first image released from OCI identifies two different communities of these microscopic marine organisms in the ocean off the coast of South Africa on Feb. 28, 2024. The central panel of this image shows Synechococcus in pink and picoeukaryotes in green. The left panel of this image shows a natural color view of the ocean, and the right panel displays the concentration of chlorophyll-a, a photosynthetic pigment used to identify the presence of phytoplankton.<\/div>\nNASA<\/div>\n<\/figcaption><\/div>\n<\/div>\n<\/div>\nDiscover more about PACE and NASA\u2019s Earth-observing fleet during an in-person celebration. The event will be hosted at NASA Headquarters in Washington, D.C., on April 18 and 19, from 9 a.m. to 3 p.m. EDT. The event will include:<\/p>\n
\n- More than a dozen hands-on Earth science activities, such as a 3D glacier puzzle and natural hazards trivia<\/li>\n
- Instructions for creating animated GIFs using NASA Earth science imagery<\/li>\n
- Opportunities to engage with the Earth Information Center, which offers data-rich visualizations and immersive experiences that show how our planet is changing.<\/li>\n
- Two new stories that will screen on the Earth Information Center\u2019s Hyperwall. One highlights how local African communities use NASA Earth science data in partnership with the Jane Goodall Institute to monitor forest habitat for chimpanzees and agricultural land use over time. The other explores how the U.S. Environmental Protection Agency monitors methane emissions from landfills with NASA remote-sensing data.\u00a0\u00a0 <\/li>\n<\/ul>\n
Online, explore how NASA works to understand our oceans at a global scale. Visit <\/a>science.nasa.gov\/earth\/earth-day\/<\/a> for dozens of resources, including:<\/p>\n\n- Downloadable guides for creating ocean currents in a test tube and a flip book showing how rivers change over time<\/li>\n
- Activities that show the importance of water on our planet and how researchers study our oceans and waterways<\/li>\n<\/ul>\n
