ASTRONAUTS COMPLETE NEARLY 5 1/2 HOUR SPACEWALK TO REPAIR SPACE STATION

FROM: NASA

NASA astronauts Rick Mastracchio and Mike Hopkins completed a 5 hour and 28 minute spacewalk Saturday to remove a faulty ammonia pump on the International Space Station. A second spacewalk to install a new unit now is scheduled for Tuesday, Dec. 24.

The extra day will allow time for the crew to resize a spare spacesuit on the space station for use by Mastracchio. During repressurization of the station’s airlock following the spacewalk, a spacesuit configuration issue put the suit Mastracchio was wearing in question for the next excursion -- specifically whether water entered into the suit’s sublimator inside the airlock. The flight control team at NASA's Johnson Space Center in Houston decided to switch to a backup suit for the next spacewalk.

This issue is not related to the spacesuit water leak that was seen during a July spacewalk by European Space Agency astronaut Luca Parmitano and NASA’s Chris Cassidy. Both Mastracchio and Hopkins reported dry conditions repeatedly throughout Saturday’s activities and the two were never in danger.
NASA Television coverage of Tuesday’s spacewalk will begin at 6:15 a.m. EST. The spacewalk scheduled to begin at 7:10 a.m.

ROCKET PREPPED FOR LAUNCH ON RESUPPLY MISSION TO ISS

FROM: NASA

An Orbital Science Corporation Antares rocket is seen on Tuesday, Dec. 16, 2013 as it is rolled out to launch Pad-0A at NASA's Wallops Flight Facility in Wallops Island, VA. The Antares is scheduled to launch a Cygnus spacecraft on a cargo resupply mission to the International Space Station on Thursday, Dec. 19 at 9:19 p.m. EST. The Orbital-1 mission is Orbital Sciences' first contracted cargo delivery flight to the space station for NASA. Among the cargo aboard Cygnus set to launch to the space station are science experiments, crew provisions, spare parts and other hardware. Weather permitting, it may be widely visible along the east coast of the United States. > Map of Orbital-1 Launch Viewing Image Credit: NASA/Bill Ingalls

A LOOK AT THE YELLOWKNIFE ON MARS

FROM: NASA
Yellowknife Bay Formation on Mars

This mosaic of images from Curiosity's Mast Camera (Mastcam) shows geological members of the Yellowknife Bay formation. The scene has the Sheepbed mudstone in the foreground and rises up through Gillespie Lake member to the Point Lake outcrop. These rocks record superimposed ancient lake and stream deposits that offered past environmental conditions favorable for microbial life. Rocks here were exposed about 70 million years ago by removal of overlying layers due to erosion by the wind.

The scene is a portion of a 111-image mosaic acquired during the 137th Martian day, or sol, of Curiosity's work on Mars (Dec. 24, 2012). The foothills of Mount Sharp are visible in the distance, upper left, southwest of camera position. Image Credit: NASA-JPL-Caltech-MSSS

NANOSATELLITES LAUNCHED FROM SPACE STATION

FROM: NASA
ISS038-E-003872 (19 Nov. 2013) --- Three nanosatellites, known as Cubesats, are deployed from a Small Satellite Orbital Deployer (SSOD) attached to the Kibo laboratory’s robotic arm at 7:10 a.m. (EST) on Nov. 19, 2013. Japan Aerospace Exploration Agency astronaut Koichi Wakata, Expedition 38 flight engineer, monitored the satellite deployment while operating the Japanese robotic arm from inside Kibo. The Cubesats were delivered to the International Space Station Aug. 9, aboard Japan’s fourth H-II Transfer Vehicle, Kounotori-4. Credit: NASA

NASA | The Sun Reverses its Magnetic Poles (+playlist)

STAR FLASH

What caused this outburst of V838 Mon? For reasons unknown, star V838 Mon's outer surface suddenly greatly expanded with the result that it became the brightest star in the entire Milky Way Galaxy in January 2002. Then, just as suddenly, it faded. A stellar flash like this had never been seen before -- supernovas and novas expel matter out into space. Although the V838 Mon flash appears to expel material into space, what is seen in the above image from the Hubble Space Telescope is actually an outwardly moving light echo of the bright flash. In a light echo, light from the flash is reflected by successively more distant rings in the complex array of ambient interstellar dust that already surrounded the star. V838 Mon lies about 20,000 light years away toward the constellation of the unicorn (Monoceros), while the light echo above spans about six light years in diameter. Image Credit: NASA, ESA

THE SPIDERWEB GALAXY

Looking like a spider's web swirled into a spiral, Galaxy IC 342 presents its delicate pattern of dust in this image from NASA's Spitzer Space Telescope. Seen in infrared light, faint starlight gives way to the glowing bright patterns of dust found throughout the galaxy's disk. At a distance of about 10 million light-years, IC 342 is relatively close by galactic standards, however our vantage point places it directly behind the disk of our own Milky Way. The intervening dust makes it difficult to see in visible light, but infrared light penetrates this veil easily. IC 342 belongs to the same group as its even more obscured galactic neighbor, Maffei 2. IC 342 is nearly face-on to our view, giving a clear, top-down view of the structure of its disk. It has a low surface brightness compared to other spirals, indicating a lower density of stars (seen here as a blue haze). Its dust structures show up much more vividly (red). Blue dots are stars closer to us, in our own Milky Way. New stars are forming in the disk at a healthy rate. The very center glows especially brightly in the infrared, highlighting an enormous burst of star formation occurring in this tiny region. To either side of the center, a small bar of dust and gas is helping to fuel this central star formation. Data from Spitzer's infrared array camera are shown in blue (3.6 microns), green (4.5 microns) and red (5.8 and 8.0 microns). Image Credit: NASA/JPL-Caltech

JUMPING TO WARP SPEED

This cockpit view of a hypothetical spacecraft traveling at eight-tenths the speed of light shows the visual distortions that would be experienced at such high speeds. The star field is actually being wrapped toward the front of the craft in addition to being significantly blue-shifted.
