Juno’s latest imagery from Jupiter
NASA's Juno spacecraft, now on its 11th orbit around Jupiter, continues to return jaw-dropping views of the solar systems's biggest planet from previously-unseen up-close perspectives of its colorful clouds and raging storms.
Asteroid missions on track to reach their destinations in 2018
Pioneering spacecraft from NASA and the Japanese space agency promise to reveal two unexplored asteroids later this year, officials said Wednesday, beginning surveys that will culminate in daring descents to capture samples for return to Earth, where eager scientists await a hands-on look at the specimens.
Plot thickens as New Horizons moves within year of next flyby
The final days before NASA’s New Horizons probe barrels in on its next destination on Jan. 1, 2019, should prove eventful, with scientists trying to sort out whether a distant mini-world detected by the Hubble Space Telescope more than three years ago may actually be a swarm of icy objects.
Titan drone, comet sampler picked as finalists for NASA mission
NASA has narrowed its choices for a new billion-dollar robotic space mission: A plutonium-powered quadcopter to explore the hazy landscape of Saturn's largest moon Titan, or a probe to scoop up a piece of a comet and return it to Earth.
NOAA’s GOES-16 weather satellite declared operational
An upgraded NOAA weather satellite has entered service after a year of checkouts to provide critical, rapidly-refreshed imagery to forecasters in time for next year's severe storm and hurricane seasons in the United States and the Atlantic Ocean.
GOES-S weather satellite arrives in Florida for launch preparations
NOAA's latest weather satellite, a new-generation geostationary observatory named GOES-S, landed at the Kennedy Space Center's former space shuttle runway Monday aboard a U.S. Air Force transport jet, ready to begin final preparations for launch March 1 on top of a United Launch Alliance Atlas 5 rocket.
Cassini’s farewell to Saturn
Two days before its final plunge into Saturn, the Cassini spacecraft turned its camera toward the ringed world to take a series of images for a color mosaic, capturing a last evocative close-up until a new mission reaches the planet.
Scientists suggest streaks on Martian hillsides are dry flows
Intermittent flows that appear on steep slopes on Mars are likely formed by flowing sand, and not water as some scientists previously suspected, according to a new study.
An interstellar interloper is dashing through our solar system
Astronomers say an object observed speeding through our solar system last month has an unexpected cigar-like shape and originated from another star, making it the first confirmed interstellar asteroid.
Photos: Delta 2 climbs into the night from Vandenberg Air Force Base
Launching from Vandenberg Air Force Base on California's Central Coast on its third try, United Launch Alliance's Delta 2 rocket lifted off Saturday with NOAA's JPSS 1 polar-orbiting weather satellite.
