Japan's H-IIA rocket carrying the Kirameki-2 satellite was launched from Tanegashima Space Centre in southern Tanegashima Island, Kagoshima prefecture, on January 24, 2017. Along with modernizing Japanese military communications, the satellite reportedly will be used to better monitor North Korean missile launches. (AFP Photo/JIJI Press)

On Monday, NASA’s Cassini Mission released this photo of Saturn’s outer B ring, which shows a never-before-seen level of detail. Cassini made a series of dives through the outer edge of the main ring system as it wraps up its mission, scheduled to end in September 2017. (NASA/JPL-Caltech/Space Science Institute)

On January 19, a team of four men and two women moved into their new simulated space home on Hawaii’s dormant Mauna Loa volcano to begin where they will live for the next 8 months. The team is conducting a human-behavior study that could help NASA as it develops plans for sending astronauts on deep space destinations such as Mars. (University of Hawaii via AP)

No, it’s not the Death Star from Star Wars. This is an image, taken by the Cassini spacecraft and released January 23, of Tethys, one of Saturn's larger icy moons. The resemblance to the fictional space station is due to the enormous crater, Odysseus. (NASA/JPL-Caltech/Space Science Institute)
