The team reported two weeks ago that the first attempts at observing 2014 MU69 were unsuccessful. But in their third try, on July 17, astronomers in Argentina saw the telltale sign of MU69's presence: a stellar wink.

The autumn skies over Endeavour Crater remained hazy as dust from the summer storms continued to rain down, but Opportunity encountered some unexpected and serious June gloom when her right front steering wheel jammed during the walkabout atop Perseverance Valley.

Only one spacecraft has ever visited Uranus and Neptune: Voyager 2, in the late 1980s. A new NASA report explores the reasons to go back, and what type of mission might take us there.

Curiosity has had a busy eight weeks, driving south from the Bagnold Dunes toward Vera Rubin Ridge. The path has steepened and the rover is now rapidly climbing upward with every meter traveled. It's been a productive time for arm instruments, but the drill is still not working.

NASA’s robotic Mars Exploration Program is on a troubling path of decline—and decisions must be made now in order to stop it. A new report by the Society explains why.

In another dynamic demonstration of what can be achieved when a team works together, Opportunity cruised to the top of Perseverance Valley, shot the moon, and drove into her 160th month of surface operations in May.

NASA's Parker Solar Probe spacecraft will repeatedly dive through the Sun's corona, giving scientists their first-ever up-close look at our star.

On the other side of the solar system, invisible by virtue both of the blinding glare of the sun and by the vastness of the distance, Dawn is continuing its remarkable cosmic adventure.
