  3. Water seems to flow freely on Mars

    Any areas of water could be off-limits to all but the cleanest spacecraft.

    Dark streaks that hint at seasonally flowing water have been spotted near the equator of Mars1. The potentially habitable oases are enticing targets for research. But spacecraft will probably have to steer clear of them unless the craft are carefully sterilized — a costly safeguard against interplanetary contamination that may rule out the sites for exploration.

    River-like valleys attest to the flow of water on ancient Mars, but today the planet is dry and has an atmosphere that is too thin to support liquid water on the surface for long. However, intriguing clues suggest that water may still run across the surface from time to time.

    In 2011, for example, researchers who analysed images from NASA’s Mars Reconnaissance Orbiter (MRO) spacecraft observed dark streaks a few metres wide that appeared and lengthened at the warmest time of the year, then faded in cooler seasons, reappearing in subsequent years2. “This behaviour is easy to understand if these are seeps of water,” says planetary scientist Alfred McEwen of the University of Arizona in Tucson, who led that study. “Water will darken most soils.”

    The streaks, known as recurring slope lineae, initially were found at seven sites in Mars’s southern mid-latitudes. The water may have come from ice trapped about a metre below the surface; indeed, the MRO has spotted such ice in fresh impact craters at those latitudes.

    McEwen and his colleagues have now found the reappearing streaks near the equator, including in the gargantuan Valles Marineris canyon that lies just south of it. The MRO has turned up 12 new sites — each of which has hundreds or thousands of streaks — within 25 degrees of the equator. The temperatures there are relatively warm throughout the year, says McEwen, and without a mechanism for replenishment, any subsurface ice would probably already have sublimated.

    He says that this suggests that water may come from groundwater deep in the crust, which could have implications for Martian life: “The subsurface is probably the best place to find present-day life if it exists at all because it is protected from the radiation and temperature extremes,” he says. “Maybe some of that water occasionally leaks out onto the surface, where we could see evidence for that subsurface life.”

  5. Saturn’s rings appear to form a majestic arc over the planet in this image from NASA’s Cassini spacecraft.

    This view looks toward the sunlit side of the rings from about 17 degrees above the ringplane. The image was taken with the Cassini spacecraft wide-angle camera on June 15, 2013 using a spectral filter sensitive to wavelengths of near-infrared light centered at 705 nanometers.

    The view was acquired at a distance of approximately 657,000 miles (1.1 million kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 2 degrees. Image scale is 37 miles (60 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.

    Atlantis shuttle experience simulates outer space for NASA

    Simulating outer space, the Atlantis shuttle experience is boldly going where no other has gone before,suspending an orbiter 30 feet in the air to display it in full flight mode. dedicated to NASA’s space shuttle program, the $100 million exhibit uses tunable lighting techniques to celebrate a technological marvel – as it would have appeared in action. installed in the 90,000 square feet museum at The Kennedy Space Center, american architects Pgav Destinations in collaboration with design firm Fisher Marantz stone used over 250 LED fixtures from Lumenpulse to create the dynamic scheme. the fixtures can be varied in color temperature and hue to recreate the unusual lighting conditions in space, and make it seem as if sunlight is reflecting off the orbiter.

    15 Years of the International Space Station

    The first International Space Station component, the Russian Zarya module, was launched in November 1998. In the 15 years since, NASA and its global partners have built a world class orbiting laboratory, establishing a continuous human presence in space since 2000 and paving the way for future exploration beyond.

    Arcing Towards Orbit

    In this two-minute exposure, the Soyuz TMA-11M rocket heads from Baikonur Cosmodrome in Kazakhstan towards orbit with Expedition 38 Soyuz Commander Mikhail Tyurin of Roscosmos, Flight Engineer Rick Mastracchio of NASA and Flight Engineer Koichi Wakata of the Japan Aerospace Exploration Agency onboard. The trio launched Thursday, Nov. 7, 2013 (Nov. 6 in the U.S.), bound for a docking at the International Space Station about six hours later.

    To commemorate this, RedBull, the company that sponsored Baumgartner’s flight and jump, released the above video. The video shows Baumgartner’s view during the fall, other angles, and mission data, such as g-force, altitude and airspeed.

  11. CNN: Mercury Seven astronaut Scott Carpenter dies at 88

    Astronaut Scott Carpenter, the second American to orbit Earth, died on Thursday, NASA said. He was 88.

    "We, the whole NASA family, are mourning with Scott’s family. We have lost a true pioneer. I shall long remember him not only for his smarts and courage but his incredible humor. He kept us all grounded," said NASA Administrator Charlie Bolden. "We will miss him greatly."

    Carpenter was one of the Mercury Seven astronauts chosen by NASA. He was a backup pilot for John Glenn in the preparation for America’s first manned orbital space flight in February 1962, according to a NASA biography.

    Carpenter flew the second American manned orbital flight in May of that year. Flight time was four hours and 54 minutes.

    He was born in Boulder, Colorado, and attended the University of Colorado, where he studied aeronautical engineering.

    Carpenter’s memoir, “For Spacious Skies: The Uncommon Journey of a Mercury Astronaut,” was published in 2003.
