Voyager 2 is now outside the reach of the solar wind, traveling in the interstellar medium. Unlike Voyager 1, Voyager 2 has a working plasma spectrometer so will be doing exciting new science. It is expected to last another 5 to 10 years, though not with all instruments operating.

At five years and counting, the Van Allen Probes mission continues to reshape our thinking about how Earth’s radiation belts flex and reconfigure under the influence of solar storms.

While we can measure properties of these upper layers using ground-based instruments, satellite-borne remote sensing instruments can give us a more frequent, global, and often higher spatial resolution perspective. And that is precisely what NASA’s Global-scale Observations of the Limb and Disk (GOLD) mission will deliver.

The upcoming solar eclipse isn’t just about watching the Moon block out the Sun. A suite of NASA-funded science experiments will to study the unseen effects of the eclipse on Earth's atmosphere.

On October 28th, the Cassini spacecraft flew through the geyser plume of Saturn's moon Enceladus. But Cassini was not the only spacecraft operating in the solar system that day.

Shooting video of a lumpy moon crossing the Sun and turning it into a giant googly eye is not a new activity for Curiosity, but I get a fresh thrill each time I see one of these sequences downlinked from the rover.

A Mars year's worth of Sun images from Opportunity demonstrates Mars' orbital motions as reflected in the changing apparent position of the Sun: the analemma.

LADEE ended its mission as planned with a crash into the lunar surface on April 17. Just days prior, it turned its star tracker camera toward the lunar horizon and captured a striking series of images of the lunar sunrise and zodiacal light.
