First aerial color photo of Mars rover’s “hole-in-one” landing site
NASA has released the first high-resolution aerial color image of the Opportunity rover's landing site on a sprawling Martian plain, where the airbag-cushioned robot fortuitously rolled into a Eagle Crater in January 2004, putting its scientific instruments face-to-face with a block of sedimentary rock that gave ground teams confirmation Mars was once a warmer, wetter, and habitable planet.
VideoNASA probe finds Saturn ring gap emptier than predicted
NASA's Cassini spacecraft sped through a gap between Saturn and its rings for the second time Tuesday after data from the probe's first perilous passage through the unexplored region last week found it to contain fewer potentially hazardous dust particles than expected.
U.S. instrument team to fly camera on South Korean moon mission
A camera developed by scientists at Arizona State University will join four foreign-built instruments on South Korea's first lunar orbiter set for launch at the end of 2018, NASA announced Friday.
Cassini contacts Earth after flying inside Saturn’s rings
Ground controllers at NASA's Jet Propulsion Laboratory confirmed Thursday the Cassini spacecraft survived its first trip between Saturn and its rings, the closest any probe has ever come to the planet.
VideoGravitational wave testbed repurposed as comet dust detector
In the final months of Europe's LISA Pathfinder mission, scientists have found an unexpected use for the trailblazing testbed for a future gravitational wave observatory by tracking the tiny dings made by microscopic particles that strike the spacecraft in deep space, exploiting the impacts to learn about the population of dust grains cast off by comets and asteroids across the solar system.
Cassini sails by Saturn’s moon Titan for last time
NASA's Cassini spacecraft sped by the moon Titan on Saturday, using the hazy world's gravity to slingshot the probe on a trailblazing trajectory to explore the region between Saturn's hydrogen-helium atmosphere and the planet's famous rings for the first time.
Saturn’s disk-shaped moon Atlas spotted by Cassini
One of Saturn's peculiar moons has received an up-close look from NASA's Cassini spacecraft, which sent back the best-ever pictures of Atlas, an object shaped like a flying saucer orbiting just outside the planet's rings.
New discoveries raise prospects for life on moons of Jupiter and Saturn
Scientists announced Thursday that measurements from NASA's Cassini spacecraft detected hydrogen gas, a key energy source for microbial life, in a plume gushing from a vast liquid water ocean buried beneath the icy shell of Saturn's moon Enceladus.
InSight lander’s troubled seismometer passes major test
A balky interplanetary seismic instrument that ran into technical problems in 2015, forcing a two-year delay in the launch of NASA's InSight lander to Mars, cleared a major test last week after engineers redesigned part of the sensor package, boosting confidence that the mission will be ready to blast off in May 2018.
Curiosity rover shows new signs of wheel wear
Engineers have spotted two small breaks in the treading on the left middle wheel on NASA's Curiosity rover, one of six wheels that have moved the robot nearly 10 miles across the Martian surface since landing in August 2012.
