Going Forward : This close-up image is of a 2-inch-deep hole produced using a new drilling technique for NASA’s Curiosity rover. The hole is about 0.6 inches (1.6 centimeters) in diameter. This image was taken by Curiosity’s Mast Camera (Mastcam) on Sol 2057. (via NASA)

Craters and Shadows at the Lunar Terminator : Why does the right part of this image of the Moon stand out? Shadows. The terminator line – the line between light and dark – occurs in the featured image so that just over half the Moon’s face is illuminated by sunlight. The lunar surface appears different nearer the terminator because there the Sun is nearer the horizon and therefore causes shadows to become increasingly long. These shadows make it easier for us to discern structure, giving us depth cues so that the two-dimensional image, when dominated by shadows, appears almost three-dimensional. Therefore, as the Moon fades from light to dark, shadows not only tell us the high from the low, but become noticeable for increasingly shorter structures. For example, many craters appear near the terminator because their height makes them easier to discern there. The image was taken two weeks ago when the lunar phase was waning gibbous. The next full moon, a Moon without shadows, will occur one week from today. via NASA

Orbital ATK Antares Rocket Lifts Off on Resupply Mission to the International Space Station : The Orbital ATK Antares rocket, with the Cygnus spacecraft onboard, launches from Pad-0A, Monday, May 21, 2018 at NASA’s Wallops Flight Facility in Virginia. Cygnus will deliver approximately 7,400 pounds of science and research, crew supplies and vehicle hardware to the International Space Station and its crew. (via NASA)

Jupiter Cloud Animation from Juno : How do Jupiter’s clouds move? To help find out, images taken with NASA’s Juno spacecraft during its last pass near Jupiter have been analyzed and digitally extrapolated into a time-lapse video. The eight-second time-lapse video, digitally extrapolated between two images taken only nine minutes apart, estimates how Jupiter’s clouds move over 29 hours. Abstractly, the result appears something like a psychedelic paisley dream. Scientifically, however, the computer animation shows that circular storms tend to swirl, while bands and zones appear to flow. This overall motion is not surprising and has been seen on time-lapse videos of Jupiter before, although never in this detail. The featured region spans about four times the area of Jupiter’s Great Red Spot. Results from Juno are showing, unexpectedly, that Jupiter’s weather phenomena can extend deep below its cloud tops. via NASA

Reflections of Venus and Moon : Posing near the western horizon, a brilliant evening star and slender young crescent shared reflections in a calm sea last Thursday after sunset. Recorded in this snapshot from the Atlantic beach at Santa Marinella near Rome, Italy, the lovely celestial conjunction of the two brightest beacons in the night sky could be enjoyed around the world. Seaside, light reflected by briefly horizontal surfaces of the gentle waves forms the shimmering columns across the water. Similar reflections by fluttering atmospheric ice crystals can create sometimes mysterious pillars of light. Of course, earthlight itself visibly illuminates the faint lunar night side. via NASA
