Close View of Saturn's Moon Enceladus From Oct. 28 Flyby
This unprocessed "raw" image of Saturn's icy, geologically active moon Enceladus was acquired by NASA's Cassini spacecraft during its dramatic Oct. 28, 2015 flyby in which the probe passed about 30 miles (49 kilometers) above the moon's south polar region. (More at NASA Picture of The Day)
Looking Back: International Space Station at the Start of Expedition 1
On Nov. 2, 2000, the Expedition 1 crew - Commander William M. (Bill) Shepherd of NASA and Flight Engineer Sergei Krikalev and Soyuz Commander Yuri Gidzenko of Roscosmos - arrived at the International Space Station, marking the start of an uninterrupted human presence on the orbiting laboratory.

NASA is developing and demonstrating technologies to service and repair satellites in distant orbits. This photo looks closely at one of the tools that could be used for satellite servicing in the future: the Visual Inspection Poseable Invertebrate Robot (VIPIR), a robotic, articulating borescope equipped with a second motorized, zoom-lens camera.

NASA's Armstrong Flight Research Center engineers are working on an increasingly complex aircraft called the Preliminary Research Aerodynamic Design to Lower Drag, or Prandtl-D. The aircraft features a new method for determining the shape of the wing with a twist that could lead to an 11-percent reduction in fuel consumption. (More at NASA Picture of The Day)
Orion Service Module Stacking Assembly Secured For Flight
The Orion spacecraft service module stacking assembly interface ring and stack holding stand are secured on a special transportation platform and are being loaded into NASA's Super Guppy aircraft at the Shuttle Landing Facility at Kennedy Space Center. On Nov. 3, the Guppy flew from Kennedy to Glenn Research Center's Plum Brook Station facility. (More at NASA Picture of The Day)
Ophir Chasma forms the northern portion of the vast Mars canyon system Valles Marineris, and this image, acquired on Aug. 10, 2015, by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter, features a small part of its wall and floor.

Scott Kelly on the Second Spacewalk of Expedition 45
On Nov. 6, 2015, NASA astronauts Scott Kelly and Kjell Lindgren spent 7 hours and 48 minutes working outside the International Space Station on the 190th spacewalk in support of station assembly and maintenance. The astronauts restored the port truss (P6) ammonia cooling system to its original configuration, the main task for the spacewalk. (More at NASA Picture of The Day)

Veiny 'Garden City' Site and Surroundings on Mount Sharp, Mars
This March 27, 2015, view from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover shows a site with a network of prominent mineral veins below a cap rock ridge on lower Mount Sharp. (More at NASA Picture of The Day)
NASA astronaut Kjell Lindgren took this photograph on Nov. 11, 2015 from the International Space Station. Lindgren wrote, "The delicate fingerprints of water imprinted on the sand. The #StoryOfWater." (More at NASA Picture of The Day)
Although Dione (near) and Enceladus (far) are composed of nearly the same materials, Enceladus has a considerably higher reflectivity than Dione. (More at NASA Picture of The Day)
Early November 2015 brought cloudy skies and intriguing patterns over the Prince Edward Islands in the South Indian Ocean. The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Terra satellite captured this scene on November 5. (More at NASA Picture of The Day)
The Apollo 12 Lunar Module (LM), in a lunar landing configuration, is photographed in lunar orbit from the Command and Service Modules (CSM) on Nov. 19, 1969. Aboard the LM were astronauts Charles Conrad Jr., commander; and Alan L. Bean, lunar module pilot. (More at NASA Picture of The Day)
Northwest Australia From the Space Station's EarthKAM
This image of the northwest corner of Australia was snapped by a student on Earth after remotely controlling the Sally Ride EarthKAM aboard the International Space Station. The program allows students to request photographs of specific Earth features, which are taken by a special camera mounted on the station when it passes over these features.

Historic Formation Flight of NASA's WB-57s Over Houston
NASA's three WB-57s fly over foggy downtown Houston, Texas during their historic formation flight over the area on Nov. 19, 2015. This photo flight was the first time that all three WB-57s have been aloft simultaneously since the early 1970s, when the U.S. Air Force had an operational squadron of WB-57s.

This curious galaxy — only known by the seemingly random jumble of letters and numbers 2MASX J16270254+4328340 — has been captured by the NASA/ESA Hubble Space Telescope dancing the crazed dance of a galactic merger. The galaxy has merged with another galaxy leaving a fine mist, made of millions of stars, spewing from it in long trails. (More at NASA Picture of The Day)
In July 2015, researchers announced the discovery of a black hole that grew much more quickly than its host galaxy. The discovery calls into question previous assumptions on development of galaxies. The black hole was discovered using the Hubble Space Telescope, and detected in the Sloan Digital Sky Survey, by ESA's XMM-Newton and NASA's Chandra. (More at NASA Picture of The Day)
