NASA has released a series of stunning images taken during the Cassini spacecraft’s last close flyby of Saturn’s moon Dione.

The images show a pockmarked landscape looming below the spacecraft.  Cassini passed 295 miles above Dione’s surface at 2:33 p.m. ET on Aug. 17, its fifth close encounter with Saturn’s icy moon. The spacecraft, which has been exploring Saturn and its moons since 2004, made its closest-ever Dione flyby in Dec. 2011 when it passed within 60 miles of the moon’s surface.

"I am moved, as I know everyone else is, looking at these exquisite images of Dione's surface and crescent, and knowing that they are the last we will see of this far-off world for a very long time to come," said Carolyn Porco, Cassini imaging team lead at the Space Science Institute, Boulder, Colorado, in a statement on the NASA website. "Right down to the last, Cassini has faithfully delivered another extraordinary set of riches. How lucky we have been."

Only a handful of close flybys of Saturn's large, icy moons remain for the spacecraft, according to NASA. Cassini is scheduled to make three approaches to the geologically active moon Enceladus on Oct. 14 and 28, and Dec. 19, passing just 30 miles from its surface on Oct. 28. “Cassini will make its deepest-ever dive through the moon's plume of icy spray at this time, collecting valuable data about what's going on beneath the surface,” explained NASA.

After December there are a handful of distant flybys planned for Saturn's large, icy moons at ranges of less than about 30,000 miles, the space agency said. “Cassini will, however, make nearly two dozen passes by a menagerie of Saturn's small, irregularly shaped moons -- including Daphnis, Telesto, Epimetheus and Aegaeon -- at similar distances during this time,” it added. “These passes will provide some of Cassini's best-ever views of the little moons.”

The Dione pictures are the latest in a series of a stunning space images. One-year astronaut Scott Kelly took an incredible aurora picture from the International Space Station last week and India's Mars orbiter recently captured beautiful 3D images of the red planet.

The Cassini-Huygens mission concludes in late 2017, with the spacecraft repeatedly diving through the space between Saturn and its rings during its final year.
