Meet Rob Navias: Public Affairs Officer and Mission Commentator  

Editor’s note: This interview was conducted in October 2023.  As the International Space Station approaches 25 years of continuous human presence on Nov. 2, 2025, it is a meaningful moment to recognize those who have been there since the beginning—sharing the story of human spaceflight with the world.    If you have ever witnessed the live […]

NASA’s Perseverance Rover Scours Mars for Science

In addition to drilling rock core samples, the science team has been grinding its way into rocks to make sense of the scientific evidence hiding just below the surface. On June 3, NASA’s Perseverance Mars rover ground down a portion of a rock surface, blew away the resulting debris, and then went to work studying […]

Buoyant Rover for Under Ice Exploration

Researchers at NASA’s Jet Propulsion Laboratory are developing the Buoyant Rover for Under-Ice Exploration, a technology that could one day explore oceans under the ice layers of planetary bodies. The prototype was tested in arctic lakes near Barrow, Alaska.

Europa: Ocean World

Scientists think there is an ocean within Jupiter’s moon Europa. NASA-JPL astrobiologist Kevin Hand explains why scientists are so excited about the potential of this ice-covered world to answer one of humanity’s most profound questions.

Europa’s Stunning Surface

The puzzling, fascinating surface of Jupiter’s icy moon Europa looms large in this newly-reprocessed color view, made from images taken by NASA’s Galileo spacecraft in the late 1990s. This is the color view of Europa from Galileo that shows the largest portion of the moon’s surface at the highest resolution. The view was previously released […]

Reddish Bands on Europa

This colorized image of Europa is a product of clear-filter grayscale data from one orbit of NASA’s Galileo spacecraft, combined with lower-resolution color data taken on a different orbit.

Source Region for Possible Europa Plumes

This reprojection of the official USGS Europa basemap is centered at the estimated source region for potential plumes that might have been detected using the Hubble Space Telescope. The view is centered at -65 degrees latitude, 183 degrees longitude. In addition to the plume source region, the image also shows the hemisphere of Europa that […]

3-D Cilix Crater on Europa

This view of Cilix impact crater on Europa was created in 2013 using 3-D stereo images taken by NASA’s Galileo spacecraft, combined with advanced image processing techniques. The crater has a diameter of about 11 miles (18 kilometers). This image, which combines a 3-D Digital Elevation Model, or DEM, with original imagery, shows that the […]

Cracks and Ridges on Europa

This enhanced color image shows cracks and ridges on Europa’s surface that reveal a detailed geologic history. Some ridges, such as the prominent one at top right, develop into long, arc-shaped “cycloids” that may be related to changing tidal forces as Europa orbits Jupiter. The wall of this ridge stands perhaps a third of a […]
