NASA’s extensive fleet of science assets, particularly those orbiting and roving Mars, have front row seats to image and study a once-in-a-lifetime comet flyby on Sunday, Oct. 19. Comet C/2013 […]
NASA’s Curiosity Mars rover has collected its first taste of the layered mountain whose scientific allure drew the mission to choose this part of Mars as a landing site. Late […]
NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft is nearing its scheduled Sept. 21 insertion into Martian orbit after completing a 10-month interplanetary journey of 442 million miles (711 million […]
The Dawn spacecraft has resumed normal ion thrusting after the thrusting unexpectedly stopped and the spacecraft entered safe mode on September 11. That anomaly occurred shortly before a planned communication […]
The European Space Agency’s Rosetta’s lander, Philae, will target Site J, an intriguing region on comet 67P/Churyumov-Gerasimenko that offers unique scientific potential, with hints of activity nearby, and minimum risk […]
On Sept. 21, 2014, the Mars Atmosphere and Volatile Evolution spacecraft will complete roughly 10 months of travel and enter orbit around the Red Planet. The orbit-insertion maneuver will be […]
NASA’s Mars Curiosity rover has reached the Red Planet’s Mount Sharp, a Mount-Rainier-size mountain at the center of the vast Gale Crater and the rover mission’s long-term prime destination. “Curiosity […]
A NASA instrument aboard the European Space Agency’s (ESA’s) Rosetta orbiter has successfully made its first delivery of science data from comet 67P/Churyumov-Gerasimenko. The instrument, named Alice, began mapping the […]
NASA’s Pluto-bound New Horizons spacecraft has traversed the orbit of Neptune. This is its last major crossing en route to becoming the first probe to make a close encounter with […]
The European Space Agency’s Rosetta mission has chosen five candidate landing sites on comet 67P/Churyumov-Gerasimenko for its Philae lander. Philae’s descent to the comet’s nucleus, scheduled for this November, will […]
NASA’s most advanced roving laboratory on Mars celebrates its second anniversary since landing inside the Red Planet’s Gale Crater on Aug. 5, 2012, PDT (Aug. 6, 2012, EDT). During its […]
NASA’s Mars Odyssey spacecraft has successfully adjusted the timing of its orbit around Mars as a defensive precaution for a comet’s close flyby of Mars on Oct. 19, 2014. The […]
NASA’s Cassini spacecraft will execute the largest planned maneuver of the spacecraft’s remaining mission on Saturday, Aug. 9. The maneuver will target Cassini toward an Aug. 21 encounter with Saturn’s […]
After a decade-long journey chasing its target, the European Space Agency’s Rosetta, carrying three NASA instruments, became the first spacecraft to rendezvous with a comet. The last of a series […]
NASA is taking steps to protect its Mars orbiters, while preserving opportunities to gather valuable scientific data, as Comet C/2013 A1 Siding Spring heads toward a close flyby of Mars […]
Comet C/2013 UQ4 (Catalina) has been observed by NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) spacecraft just one day after passing through its closest approach to the sun. The […]
Surface structures are becoming visible in new images of comet 67P/Churyumov-Gerasimenko taken by the scientific imaging system OSIRIS onboard the European Space Agency’s Rosetta spacecraft. The resolution of these images […]
As the European Space Agency’s spacecraft Rosetta is slowly approaching its destination, comet 67P/Churyumov-Gerasimenko, the comet is again proving to be full of surprises. New images obtained by OSIRIS, the […]
In July 2015, NASA will discover a new world. No one knows what to expect when the alien landscape comes into focus. There could be icy geysers, towering mountains, deep […]
With its solar panels their cleanest in years, NASA’s decade-old Mars Exploration Rover Opportunity is inspecting a section of crater-rim ridgeline chosen as a priority target due to evidence of […]
