The Cassini mission has already returned an array of images of other solar system members from Saturn orbit: Earth (and the Moon), Venus, Mars, and Jupiter. It’s time to add another world to that list!

The Green Bank Telescope has been called into emergency service to play radar ping-pong on a close-by asteroid with Arecibo Observatory’s 100-meter William E. Gordon radio telescope.

After completing the initial reconnaissance of the Kimberley outcrop two weeks ago, Curiosity is, at last, moving toward a drill site. The science team selected the location last week: a spot near the base of Mount Remarkable, into what they have been calling the

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.

How did planets originate? This is a question that has puzzled scientists for centuries, but one which they have been able to tackle directly only in the last few decades, thanks to two major developments: breakthroughs in telescope technology and ever-increasing computing power.

The Opportunity rover and the Lunar Reconnaissance Orbiter are both zeroed out in NASA's 2015 budget. Learn why these missions face the axe and why the White House is forcing NASA to choose between existing missions and starting new ones.

Imagine yourself on a windswept landscape of rocks and red dust with mountains all around you. The temperature -- never warm on this planet -- suddenly plunges, as the small Sun sets behind the western range of mountains.

Curiosity has been busy performing a survey of the Kimberley, walking the length of the outcrop and taking enormous quantities of photos. The team is now ready to go in for a closer look, and maybe even to drill.

Mawrth Vallis was axed as a landing site for Curiosity, but will we get a chance to explore it with ESA's ExoMars rover?

We don’t hear a lot at the moment about Chang’E 3 and Yutu, the Chinese lander and rover which were all over the news a few months ago. But Phil Stooke has been collecting news online and in person last month at the Lunar and Planetary Science Conference and now tries to put it all together and address the current state of the mission.

While climbing Murray Ridge, Opportunity enjoyed a major cleaning event that has left the rover's solar panels more dust-free than they have been in years. The rover captured a pretty panorama of the newly clean deck with its Pancams, and James Sorenson processed the version shown here.

Early in the morning on January 13, 2014, a 6.4 magnitude earthquake struck beneath the Atlantic Ocean north of Puerto Rico, damaging Arecibo Observatory, the world’s largest single-dish radio telescope. The telescope is now operational after repairs and scientists have resumed observations. However, the future of Arecibo Observatory remains unclear due to funding uncertainties in the federal budget.

The Mars Express team showcases some of the best viewing opportunities of Mars in 2014, including how to spot Comet Siding Spring when it flies past Mars this October.

At the Solander Point section of the rim of Endeavour Crater, Mars Exploration Rover Opportunity spent the month of March just off Murray Ridge working on its final targets in Cook Haven and dusting itself in the winds of winter, while MER mission officials on Earth were roving toward what may be the robot's current greatest potential threat – being cut from NASA's planetary science budget.
