“On 18 September 2017, ESA astronaut Paolo Nespoli shot this beautiful time-lapse showing the Moon rising above the Earth’s horizon together with Mercury, Mars, the star Regulus, and Venus. ESA astronaut Paolo Nespoli is currently working and living on board the International Space Station as part of his long duration Vita mission.”

“June 3, 2016. Rhea, like many moons in the outer solar system, appears dazzlingly bright in full sunlight. This is the signature of the water ice that forms most of the moon’s surface. Rhea (949 miles or 1,527 kilometers across) is Saturn’s second largest moon after Titan. Its ancient surface is one of the most heavily cratered of all of Saturn’s moons. Subtle albedo variations across the disk of Rhea hint at past geologic activity.

This view looks toward the anti-Saturn hemisphere of Rhea. North on Rhea is up and rotated 36 degrees to the right. The image was taken with the Cassini spacecraft narrow-angle camera using a spectral filter which preferentially admits wavelengths of ultraviolet light centered at 338 nanometers. The view was acquired at a distance of approximately 365,000 miles (587,000 kilometers) from Rhea and at a Sun-Rhea-spacecraft, or phase, angle of 9 degrees. Image scale is 2.4 miles (3.9 kilometers) per pixel.”

“April 2, 2016. Saturn’s main rings, along with its and moons, are much brighter than most stars. As a result, much shorter exposure times (10 milliseconds, in this case) are required to produce an image and not saturate the detectors of the imaging cameras on NASA’s Cassini spacecraft. A longer exposure would be required to capture the stars as well. Cassini has captured stars on many occasions, especially when a target moon is in eclipse, and thus darker than normal. Dione (698 miles, 1123 kilometers across) and Epimetheus (70 miles, 113 kilometers across) are seen in this view, above the rings at left and right respectively.

This image looks toward the sunlit side of the rings from about 3 degrees above the ring plane. The image was taken in visible light with the Cassini spacecraft wide-angle camera. The view was obtained at a distance of approximately 257,000 miles (413,000 kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 34 degrees. Image scale is 15 miles (25 kilometers) per pixel.”

“NASA scientists and engineers named their new CubeSat after the mythological Norse god of the dawn. Now, just days from launch, they are confident the shoebox-sized satellite Dellingr will live up to its name and inaugurate a new era for scientists wanting to use small, highly reliable satellites to carry out important, and in some cases, never-before-tried science. Dellingr will study how the ionosphere, a region in Earth’s upper atmosphere, interacts with the Sun. Before launch, Dellingr is required to visit to the Magnetic Test Facility at NASA Goddard to test the spacecraft’s magnetometers – key instruments for measuring the direction and strength of the magnetic fields that surround Earth. The spacecraft is scheduled to launch this August aboard a SpaceX Falcon 9 rocket to the International Space Station where it will be deployed later into a low-Earth orbit.

“December 6, 2015. NASA’s Cassini spacecraft captured this view of Saturn’s moon Epimetheus (116 kilometers, or 72 miles across) during a moderately close flyby. This is one of Cassini’s highest resolution views of the small moon. This view looks toward the Saturn facing side of Epimetheus. North on Epimetheus is up. The image was taken in green polarized light with the Cassini spacecraft narrow-angle camera.

The view was acquired at a distance of approximately 22,000 miles (35,000 kilometers) from Epimetheus and at a Sun-Epimetheus-spacecraft, or phase, angle of 28 degrees. Image scale is 697 feet (212 meters) per pixel.”
