New Horizons’ next target might be a binary pair
Ground observations of the New Horizons spacecraft's next target last month revealed the distant object, lurking in the outer solar system more than four billion miles from Earth, might have an unconventional elongated shape, or even consist of two icy bodies orbiting one another in an age-old cosmic dance.
Planetary protection is serious business at NASA
A NASA post advertising an opening for a new Planetary Protection Officer provided a field day for headline writers who apparently couldn't resist having a bit of fun at the agency's expense by suggesting, in large type, that whoever filled the post would be defending Earth from aliens. And making good money to boot.
Opportunity rover peers into ‘Perseverance Valley’
NASA's Opportunity rover, now showing nearly 28 miles on its odometer since landing on Mars, recorded a panoramic view last month of its next scientific destination, a valley that may have been carved by water, an icy or muddy debris flow, or ancient Martian winds.
First images of Jupiter’s Great Red Spot reach Earth
Two days after NASA's Juno spacecraft streaked over Jupiter's Great Red Spot, pictures of the solar system's largest, most powerful storm, have been transmitted to Earth, giving eager scientist close-up views of the 10,000-mile-wide anticyclone where 400-mph winds have been howling for at least 187 years and possibly much longer.
BepiColombo Mercury mission tested for journey into ‘pizza oven’
Three spacecraft built in Europe and Japan have completed their final joint tests to ensure they are ready for departure to Mercury on an Ariane 5 rocket late next year on the nearly $1.9 billion BepiColombo mission to survey the solar system's innermost planet.
NASA marks 20 years of continuous Mars exploration
NASA's Mars Pathfinder probe dropped to the surface of Mars for an airbag-cushioned landing 20 years ago Tuesday, bouncing 15 times across an ancient flood plain before deploying a mobile robot to usher in two decades of uninterrupted Martian exploration.
Dawn mission managers await NASA decision on spacecraft’s future
The future of NASA's Dawn spacecraft, running low on hydrazine fuel and now flying around the dwarf planet Ceres without the help of internal pointing wheels, will be decided in the coming weeks by top space agency managers.
VideoRide with NASA’s Juno orbiter over turbulent Jupiter
Take a trip around Jupiter with NASA's Juno spacecraft in a time-lapse animation created from a sequence of images taken during the probe's last close-up flyby of the gas giant May 19.
Cassini survives closest brush with Saturn’s inner ring
Barreling through space near the inner edge of Saturn's wispy D ring, NASA's Cassini spacecraft shielded from itself bits of ice and dust Sunday as the probe made its most dangerous plunge close to the planet, collecting spectacular edge-on views of Saturn's rings with an on-board camera.
Jupiter surprises in first trove of data from NASA’s Juno mission
The first months of observations of the solar system's biggest planet from NASA's Juno spacecraft have revealed huge swirling polar cyclones, previously-undetected structures and motions beneath Jupiter's distinctive clouds, and the first evidence for what lies at the core of the gas giant, scientists said Thursday.
