This week at NASA: This week @ NASA: The first possible sound of a tsunami



What could be the first sound of a marsquake … Helping the astronauts break the dust in future missions to the moon … And celebrate our home planet … some of the stories to tell – This week at NASA!

InSight Lander Captures Audio of the First "Quake" on Mars

An instrument in our Mars InSight lander measured and recorded for the first time a probable marsquake.

Marsquake's audio

The weak seismic signal, detected by the Experimental Seismic Instrument for Interior Structure, was recorded on April 6. It is the first recorded quake that seems to have come from within the planet, as opposed to being caused by wind and other forces above the surface. Scientists are still examining the data to determine the exact cause of the signal. The InSight mission is studying the deep interior of Mars, to learn more about how it and other rocky worlds, including the Earth and the Moon, have formed.

Test technology to combat lunar dust

A technology being developed by researchers at our Kennedy Space Center could help keep the nasty dust away from difficult places in space suits and other equipment used by astronauts in future exploration missions to the moon and other planetary surfaces. The Electrodynamic Dust Shield, or EDS, recently launched on the International Space Station on the Northrop Grumman Cygnus spacecraft. The technology, which uses dynamic electric fields to remove dust from surfaces, has been tested extensively on Earth, but next year at the space station will provide invaluable data that could be used for future missions on the Moon and Mars. NASA is working to send US astronauts to the moon by 2024 – specifically to the lunar South Pole – a place no man had ever seen before.

NASA celebrates Earth Day

For Earth Day, we invite the public to help celebrate the beauty of our home planet with a global social media event and local events across the country. As part of our Earth of the Image event, social media users all over the world posted photos of their favorite natural features. To help inspire them, we we share some of the Earth's most impressive images from space. Some photos uploaded by the public may be displayed on future NASA projects. Meanwhile, local events such as our Earth Day in the Nation's CapitalUnion Station in Washington D.C., were full of demonstrations and practical activities to help illustrate as we explore our home planet and beyond.

Interactive "Space for the US"

"Space for the US" is our new interactive website that highlights how Earth's observations from space help strengthen communities in the United States and inform decisions about public health, disaster response, and environmental protection. The site features 56 stories illustrating how NASA science has impacted all states of the country, as well as the District of Columbia, Puerto Rico, and regions along the Atlantic, Pacific, Gulf of Mexico, and Great Lakes. For six decades, NASA used the space viewpoint to better understand our planet and improve lives. Try the site for yourself at nasa.gov/spaceforus.

This is what it is this week @NASA …
