All Good Things: Countdown Begins Toward Cassini's 'Grand Finale' Around Saturn

Artist’s concept of Cassini’s final orbits between the Saturn’s innermost rings and the planet’s cloud tops. This set of orbits will consist the last leg of Cassini’s mission, called “The Grand Finale,” which will culminate with a plunge on Saturn’s atmosphere in September 2017.

New Spectacular Images of Pluto From New Horizons Reveal an Exotic, Dynamic World

A breathtaking, dramatic image of Pluto backlit by the distant Sun, taken by NASA’s New Horizons spacecraft a few hours after its closest approach, on July 14, while at a distance of 2 million km away from the planet. Besides its unparalleled aesthetic quality, this image provided scientists with important information about the structure […]

On the Final Path: New Horizons Executes Last Course Correction Maneuver Prior to Pluto Closest Approach

With just under two weeks remaining before New Horizons flies through the Pluto system on July 14, the spacecraft has successfuly executed its last scheduled course correction maneuver, which put it right on top of the mission’s intended trajectory through the Pluto system.

New Study Suggests Pluto's Charon May Have Harbored Underground Oceans Long Ago

An artist’s depiction of Pluto, as seen from the surface of its largest moon Charon. A recent study by a team of US astronomers argues that Charon might harbor frozen underground oceans of liquid water, the pressence of which could be inferred by surface geologic features that could be visible to the New Horizons […]

Pluto Slowly Transitions From Astronomical Point Source to Fascinating World in Latest Images From New Horizons

Pluto is revealed as a fascinating planetary world in these latest images that were taken by New Horizons spacecraft between May 29-June 2. The images show four different “faces” of Pluto as it rotates about its axis with a period of 6.4 days. All the images have been rotated to align Pluto’s rotational axis […]

Pluto Comes Into Focus in Latest Images as New Horizons Approaches Ever Closer

NASA’s New Horizons spacecraft took a series of images of Pluto in 8-12 May from a decreasing distance of 110 million to 75 million km away, which provide fascinating new views of the distant planet’s largely varied surface topography. Compared to images taken one month earlier, Pluto appears to get larger as the spacecraft […]

Venus Express Spacecraft Goes Out With a Shout, Ends Triumphant Mission Around Earth's 'Twisted Sister'

An artist’s concept of ESA’s Venus Express spacecraft, while diving into the atmosphere of Venus during its aerobraking manoeuvres in 2014. Having already depleted its onboard fuel reserves, the spacecraft finally went silent earlier this month, indicating that it had probably taken its last, fateful plunge into Venus’ infernal atmosphere.
