NASA Earth science studies our planet all day, every day. By tracking the movement of our natural systems – and the effect of human activity on them – we can understand the patterns, causes and results of climate change on the elemental activities that sustain us.
On Earth Day, April 22, we take time to celebrate this wondrous planet with special discussions, events (virtual) and activities. Like our satellites, however, NASA’s Earth science goes on year-round, and we continuously create videos, activities, news and more to tell the story of what’s happening on and with our planet – and all always offered free and open to the public.
For the 50th Anniversary of Earth Day in 2020, NASA created a special package of materials designed to mark Earth Day at Home. This included activities, videos, special programs and other materials in English and Spanish. You can find them all archived here.
What are some skywatching highlights in April 2021? Look for the rosy arch known as the Belt of Venus at sunset, then find the constellation Leo overhead on April evenings. Also, check out Jupiter and Saturn with the Moon on April 6. Additional information about topics covered in this episode of What’s Up, along with still images from the video, and the video transcript, are available at https://solarsystem.nasa.gov/whats-up…
NASA is working alongside Conservation International and the Liberian Government through the Environmental Protection Agency (EPA) to pilot an innovative and replicable approach to more accurately map ecosystems to support effective planning and sustainable decision-making. NASA’s satellite data and expert analysis will provide a country-wide picture of Liberia’s hardwood forests, mangroves, and other ecosystems; Conservation International and the Liberian Government through the EPA will augment that data with their expertise in ecosystem accounting, field studies, and local knowledge to quantify the value of the country’s natural resources and related ecosystem services.
Liberia is a country in West Africa, bordering Sierra Leone, Guinea and Côte d’Ivoire. On the Atlantic coast, the capital city of Monrovia is home to the Liberia National Museum, with its exhibits on national culture and history. Around Monrovia are palm-lined beaches like Silver and CeCe. Along the coast, beach towns include the port of Buchanan, as well as laid-back Robertsport, known for its strong surf.
Every legacy has a compelling origin. The soon-to-be-launched Landsat 9 is the intellectual and technical product of eight generations of Landsat missions, spanning nearly 50 years.
Episode One answers the question “why?” Why did the specific years between 1962 and 1972 call for a such a mission? Why did leadership across agencies commit to its fruition? Why was the knowledge it could reveal important to the advancing study of earth science?
In this episode, we’re introduced to William Pecora and Stewart Udall, two men who propelled the project into reality, as well as Virginia Norwood who breathed life into new technology. Like any worthwhile endeavor, Landsat encountered its fair share of resistance. Episode one explores how those challenges were overcome with the launch of Landsat 1, signifying a bold step into a new paradigm.

The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey (USGS). Landsat satellites have been consistently gathering data about our planet since 1972. They continue to improve and expand this unparalleled record of Earth’s changing landscapes for the benefit of all.

Earth is not the only place in the solar system with rain, rivers, lakes and seas. Saturn’s moon Titan has them, too — not of water, but of liquid methane and ethane. This Earth-like world even hides an ocean of liquid water deep beneath its surface! Find out what you need to know about Titan.
