A Chang'e spacecraft swung around the Moon and its capsule landed safely on Earth — a dress rehearsal for a future mission to bring back lunar samples.
Mars-orbiting spacecraft escaped unscathed by Comet Siding Spring's close approach to the Red Planet — and unique scientific observations are now streaming back to Earth.
It's a historic day for India's maturing space program, as its first-ever interplanetary explorer successfully slipped into orbit around the Red Planet.
On September 21st, after a 33-minute-long rocket firing, NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft slipped into orbit around the Red Planet.
European space officials have decided to drop their Philae lander on November 11th onto the small end of the already-active Comet 67P/Churyumov–Gerasimenko. Success is hardly assured.
Now two years into its exploration of Mars, NASA's big rover has reached the base of the huge mound that scientists hope will reveal the Red Planet's history.
On August 25, 1989, a NASA spacecraft made its fourth and final planetary encounter. What it revealed 25 years ago about the Neptunian system is still amazing and still profound.
Mission planners have devised an unusual strategy for protecting orbiting spacecraft when Comet Siding Spring passes the Red Planet in October 2014.
On August 6th, the ESA's Rosetta spacecraft finally completed its decade-long voyage to Comet 67P/Churyumov-Gerasimenko.
Six years from now, there will be a new NASA robot heading to the Red Planet: the Mars 2020 rover. On July 31st mission planners unveiled the rover’s seven scientific instruments, which will pave the way for human exploration of Mars.
The Rosetta spacecraft is closing in on Comet 67P/C-G, providing astronomers with an ever more detailed view of its structure. Judging by the latest photos, it actually has two components and is shaped like… a rubber ducky?
New Horizons will reach Pluto a year from today, and the scientific community is abuzz with speculation about what the space probe might see when it gets there. Meanwhile, the New Horizons team scours the skies for a Kuiper Belt Object that New Horizons can visit after its Pluto flyby.
How did the the innermost planet get its huge iron core? New computer modeling suggests that Mercury is a lucky survivor of chaotic primordial smashups.
Comet 67P/Churyumov-Gerasimenko only woke briefly before starting another nap, expected on-again-off-again behavior that bodes well for the comet-chasing spacecraft's arrival in August 2014.
Despite skepticism from scientists and politicians alike, NASA is proceeding with its asteroid redirect mission and has found six candidates for exploration so far.
NASA’s crippled planet-hunting spacecraft has been reworked for at least two years of productive new missions.
Although its scientific work for NASA ended in the early 1980s, the International Sun-Earth Explorer never quite died — and this week it was revived by a team of volunteers intent on letting it continue exploring interplanetary space.
A small asteroid slammed into the Martian surface sometime between March 27 and 28, 2012, creating a crater swarm in the ground. The largest pit is 159 feet across.
The Mars rover Opportunity has been cleaned of heavy dust coating its solar panels, thanks to some strong winds blowing over the rim of Endeavour Crater.
New images from NASA’s Cassini mission show bright spots along Saturn’s A ring, likely caused by a small moonlet in the process of forming or shattering.
NASA has a fully functioning spacecraft orbiting the Moon, all science goals completed, and a lunar eclipse coming up. It's a perfect opportunity to make some risky but potentially rewarding swoops within 2 miles of the lunar surface.
The European Space Agency’s comet-chasing spacecraft has imaged its destination for the first time since waking up from 957 days of hibernation.
With the first interactive lunar north pole mosaic released by the NASA’s Lunar Reconnaissance Orbiter Camera team you can explore an area of the Moon’s northern hemisphere about the size of Alaska and Texas combined.
Now that they've seen all of the innermost planet up close, geologists realize that Mercury's crust buckled and fractured as the planet cooled and shrank far more than previously measured.
SkyCube, a crowd-funded nanosatellite built to engage the public in space exploration, has been deployed from the International Space Station. Now its creators are anxiously waiting to establish two-way contact.
