NASA spacecraft steers clear of Martian moon Phobos
ESA’s Mars Express spacecraft took this image of Phobos backdropped by the limb of Mars. Credit: ESA/DLR/FU Berlin (G. Neukum) NASA’s MAVEN spacecraft in orbit around Mars maneuvered out of the path of Phobos earlier this week after navigators predicted the spacecraft could run into the Martian moon in the near future, highlighting the challenge…

NASA’s Juno spacecraft to remain in current orbit around Jupiter
Artist’s concept of the Juno spacecraft at Jupiter. Credit: NASA/JPL-Caltech Concerns about the health of the Juno spacecraft’s main engine have compelled NASA managers to keep the research probe in its current arcing, high-altitude orbit around Jupiter, a decision that will delay the full science return from the $1.1 billion mission but should still allow…

Cassini offers best-ever view of Saturn’s rings
This image taken Dec. 18, 2016, shows a region in Saturn’s outer B ring. NASA’s Cassini spacecraft viewed this area at a level of detail twice as high as it had ever been observed before. The view here is of the outer edge of the B ring, at left, which is perturbed by the most…

Japanese spacecraft spots planet-spanning wave on Venus
In these images from Japan’s Akatsuki spacecraft, a stationary bow wave is seen on Venus over several days in December 2015. Credit: JAXA Images from Japan’s Akatsuki spacecraft have revealed a gigantic wave in the atmosphere of Venus, and scientists say it may be the largest such feature in the solar system. The bow-shaped wave…

Saturn’s shepherd moon Daphnis makes waves
The wavemaker moon, Daphnis, is featured in this view taken by the Cassini spacecraft Jan. 16. It is the closest picture of Daphnis ever taken. Each pixel measures about 551 feet (168 meters) across. Credit: NASA/JPL-Caltech/Space Science Institute NASA’s Cassini spacecraft has captured the first close-up view of Daphnis, one of at least 62 moons…

Planet Earth observed through telescope orbiting Mars
Here is a view of Earth and its moon, as seen from Mars. It combines two images acquired on Nov. 20, 2016, by the HiRISE camera on NASA’s Mars Reconnaissance Orbiter, with brightness adjusted separately for Earth and the moon to show details on both bodies. Relative sizes and distance are correct. Credit: NASA/JPL-Caltech/University of…

Internal debris may be causing problem with Mars rover’s drill
File photo of Curiosity’s drill bit from Feb. 24, 2015. Credit: NASA/JPL-Caltech/MSSS Engineers suspect a piece of foreign object debris may be intermittently stalling a motor needed to place the Curiosity Mars rover’s drill bit onto rocks, and the robot’s ground team is assessing the source of the potential contamination. More importantly, Curiosity project manager…
