The sun shines through a truss-based radiator panel and a primary solar array panel on the Earth-orbiting International Space Station (ISS) in this photograph taken by an Expedition 38 crew member on Jan. 2, 2014.
The crew on the ISS is awaiting the first commercial resupply mission to the ISS by Orbital Sciences, Orbital-1. Orbital Sciences will proceed with a 1:07 p.m. EST launch attempt of the Orbital-1 cargo resupply mission to the ISS today, Thursday, Jan. 9.
Meanwhile, as more than 30 heads of space agencies from around the world gather in Washington Jan. 9-10 for an unprecedented summit on the future of space exploration, the Obama Administration has approved an extension of the ISS until at least 2024.

The South Sandwich Islands, in the far southern Atlantic Ocean, are often shrouded with thick cloud, making it difficult to view the region from space. Sometimes, however, the use of false-color imagery can be used to reveal events that would otherwise be obscured under cloud cover.
The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite flew over the South Sandwich Islands on April 19, 2014 and acquired this false-color image of the cloudy scene.
This false-color image uses a combination of non-visible (middle infrared and infrared) and visible (red) light captured in bands 7, 2, and 1, respectively, to distinguish clouds from snow and ice. Here the ice-covered islands appear bright turquoise, the clouds light turquoise and the water in the ocean appears deep black. Because the volcanic plume is a moist mixture of gas and ash, it reflects all three forms of light relatively well, so it appears nearly white.
In the north of this image, a thin plume of white rises from the volcano on Zavodovski island, the northernmost of the South Sandwich Islands and streams to the northeast. Further south, a wider white plume can be seen blowing across the Atlantic Ocean. This plume rises from the Mount Michael volcano, which is a young and frequently active stratovolcano located on Saunders Island, near the center of the South Sandwich Island chain.
The white plume from Mount Michael forms a chain of swirling eddies as it blows to the northeast. To the south, similar eddies can be seen behind three other islands. These are known as Von Kármán vortices. These vortices can form nearly anywhere that fluid flow is disturbed by an object. Because the atmosphere behaves like a fluid, when streaming air hits a blunt object, such as a mountain peak, the wind is forced around the object. The disturbance in the flow of the wind propagates downstream in a double row of vortices that alternate their direction of rotation, much like the eddies seen behind a pier in a river as water rushes past.

The umbilical tower drops back from a United Launch Alliance Atlas V 401 rocket as it lifts off Space Launch Complex 41 on Cape Canaveral Air Force Station in Florida. Launch, with NASA’s Tracking and Data Relay Satellite-K or TDRS-K aboard, was at 8:48 p.m. EST on Jan. 30.

The TDRS-K spacecraft is part of the next-generation series in the Tracking and Data Relay Satellite System, a constellation of space-based communication satellites providing tracking, telemetry, command and high-bandwidth data return services.

ISS040-E-090540 (9 Aug. 2014) — One of the Expedition 40 crew members aboard the International Space Station photographed this nighttime image showing city lights in at least half a dozen southern states from some 225 miles above the home planet. Lights from areas in the Gulf Coast states of Texas, Louisiana, Mississippi and Alabama, as well as some of the states that border them on the north, are visible.

A supermoon rises behind the Washington Monument, Sunday, June 23, 2013, in Washington. This year the supermoon is up to 13.5% larger and 30% brighter than a typical full moon is. This is a result of the moon reaching its perigree – the closest that it gets to the Earth during the course of its orbit. During perigree on June 23, the moon was about 221,824 miles away, as compared to the 252,581 miles away that it is at its furthest distance from the Earth (apogee).

The Soyuz rocket is rolled out to the launch pad by train on Monday, Sept. 23, 2013, at the Baikonur Cosmodrome in Kazakhstan. Launch of the Soyuz rocket is scheduled for Sept. 26 and will send Expedition 37 Soyuz Commander Oleg Kotov, NASA Flight Engineer Michael Hopkins and Russian Flight Engineer Sergei Ryazansky on a five-and-a-half month mission aboard the International Space Station.

Just as Saturn’s famous hexagonal shaped jet stream encircles the planet’s north pole, the rings encircle the planet, as seen from Cassini’s position high above. Around and around everything goes!
This view looks toward the sunlit side of the rings from about 43 degrees above the ringplane. The image was taken with the Cassini spacecraft wide-angle camera on Nov. 23, 2013 using a spectral filter that preferentially admits wavelengths of near-infrared light centered at 752 nanometers.
The view was obtained at a distance of approximately 1.6 million miles (2.5 million kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 97 degrees. Image scale is 93 miles (150 kilometers) per pixel.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA’s Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.

Space Launch Complex 40 on Cape Canaveral Air Force Station in Florida is illuminated by a Falcon 9 rocket as it lifts off at 8:35 p.m. EDT carrying a Dragon capsule to orbit. Space Exploration Technologies Corp., or SpaceX, built both the rocket and capsule for NASA’s first Commercial Resupply Services, or CRS-1, mission to the International Space Station.

SpaceX CRS-1 is an important step toward making America’s microgravity research program self-sufficient by providing a way to deliver and return significant amounts of cargo, including science experiments, to and from the orbiting laboratory. NASA has contracted for 12 commercial resupply flights from SpaceX and eight from the Orbital Sciences Corp.

On May 23, 2014, Expedition 40 Commander Steve Swanson posted this photograph — taken from the International Space Station — to Instagram. Swanson noted, “Western Sahara – the contrast between the sand and the water is spectacular from here.” Swanson uploaded the first image from space to Instagram on April 7. He began posting imagery to the social media site during his pre-flight training.

Saturn’s north polar hexagon basks in the Sun’s light now that spring has come to the northern hemisphere. Many smaller storms dot the north polar region and Saturn’s signature rings, which appear to disappear on account of Saturn’s shadow, put in an appearance in the background.

The image was taken with the Cassini spacecraft’s wide-angle camera on Nov. 27, 2012 using a spectral filter sensitive to wavelengths of near-infrared light centered at 750 nanometers.

The view was acquired at a distance of approximately 403,000 miles (649,000 kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 21 degrees. Image scale is 22 miles (35 kilometers) per pixel.
