A rare solar eclipse will take place on August 21 over parts of the United States - and chasing its shadow 10 miles above the Earth will be two NASA jets collecting data.

NASA’s Cassini mission has shared an amazing close-up portrait of Saturn taken from the Cassini robotic probe. The image was taken with Cassini’s narrow-angle camera on May 18, 2017, using a combination of spectral filters which preferentially admit wavelengths of near-infrared light. The view was obtained at a distance of 750,000 miles (1.2 million km) [...]

Cassini will soon destroy itself in Saturn's atmosphere, but its dramatic death plunge is all for the good of science.

NASA's Cassini Probe begins maneuvers to study Saturn's atmosphere, coming within 1,000 miles of the gas giant's surface on a path toward the spacecraft's ultimate demise.

Mere weeks away from its dramatic, mission-ending plunge into Saturn, NASA's Cassini spacecraft has a hectic schedule, orbiting the planet every week in its Grand Finale. On a few orbits, Saturn's largest moon, Titan, has been near enough to tweak Cassini's orbit, causing the spacecraft to approach Saturn a bit closer or a bit farther away. A couple of those distant passes even pushed Cassini into the inner fringes of Saturn's rings.
