Titan's siblings must be jealous. While most of Saturn's moons display their ancient faces pockmarked by thousands of craters, Titan -- Saturn's largest moon -- may look much younger than it really is because its craters are getting erased. Dunes of exotic, hydrocarbon sand are slowly but steadily filling in its craters, according to new research using observations from NASA's Cassini spacecraft.

"TopCoder, Inc., the world's largest competitive Community of digital creators, today announced the Longeron Shadowing Optimization Challenge, a $30,000, open to the public competition to make the energy-gathering solar arrays of the International Space Station (ISS) more efficient by eliminating the shadows it casts upon itself at different points during orbit. Registration for the three week long competition is now open with competition ending Wednesday, February 6 th at 18:00 GMT. Contestants must be TopCoder members in good standing. Community membership and challenge registration are free. Top prizes include $10,000 for the best solution with second and third placed solutions earning $5,000 and $3,000 respectively. Bonus prizes of mission stickers which have actually orbited the Earth on Space Shuttle Endeavour will be awarded to the top 5 finishers." More

Expandable Module On The Space Station

NASA Deputy Administrator Lori Garver announced Wednesday a newly planned addition to the International Space Station that will use the orbiting laboratory to test expandable space habitat technology.

ESA agreed with NASA today to contribute a driving force to the Orion spacecraft planned for launch in 2017. Ultimately, Orion will carry astronauts further into space than ever before using a module based on Europe's Automated Transfer Vehicle technology.

"NASA's Space Technology Program is looking for visionary advanced concepts. This year's annual call for NASA's Innovative Advanced Concepts Program (NIAC) is seeking proposals for revolutionary concepts with the potential to transform future aerospace missions. Proposed concepts should enable new missions or significantly improve current approaches to achieve aerospace objectives. NIAC studies visionary aerospace architecture, system or mission concepts that are exciting and unexplored, yet credible and executable. The concepts are early in development -- generally 10 years or more from operation. They are chosen based on peer review of the potential impact, technical strength and benefits of the proposed study. "While Goddard or Tsiolkovsky envisioned rockets taking humans to space, the rest of the world focused on the industrial revolution and challenges of the early 20th century," said Michael Gazarik, director of NASA's Space Technology Program at the agency's headquarters in Washington. "These visionaries had radical ideas of space travel and exploration that would take dozens to hundreds of years for maturation, but were worth waiting for. NASA's NIAC seeks proposals from today's visionaries who have futuristic concepts that may transform how we live, work and explore the high frontier." More

MRO Image of Mars: A Circular Crack

This circular crack is very odd-looking. When you zoom in to HiRISE scale, the crack looks a lot like a graben.

Air Quality Suffering in China

Residents of Beijing and many other cities in China were warned to stay inside in mid-January 2013 as the nation faced one of the worst periods of air quality in recent history.

NASA and its international partners have named several future International Space Station expedition crews. They include NASA astronauts Steve Swanson, Reid Wiseman, Barry Wilmore and Terry Virts.

Landsat Data Continuity Mission Update

On January 10th NASA held a news briefing to discuss the upcoming launch of the Landsat Data Continuity Mission (LDCM) scheduled for February 11. This mission is a collaboration between NASA and the U.S. Geological Survey.

Hydrae Chasma is a deep, circular depression approximately 50 kilometers across, situated between Juventae Chasma to the north and the large canyon system Valles Marineris to the south.

The National Aeronautics and Space Administration (NASA) is soliciting the submission of multiinstitutional team-based proposals for research as participating members of the Solar System Exploration Research Virtual Institute (SSERVI), hereafter referred to as "the Institute."

An Asteroid Belt Around Vega?

Astronomers have discovered what appears to be a large asteroid belt around the star Vega, the second brightest star in northern night skies. The scientists used data from NASA's Spitzer Space Telescope and the European Space Agency's (ESA) Herschel Space Observatory, in which NASA plays an important role.

Rogue Planetary Orbit for Fomalhaut B

Newly released NASA Hubble Space Telescope images of a vast debris disk encircling the nearby star Fomalhaut and a mysterious planet circling it may provide forensic evidence of a titanic planetary disruption in the system.

"National Aeronautics and Space Administration (NASA) Headquarters is releasing a NASA Research Announcement (NRA) for initial studies of visionary aerospace concepts. NNH13ZUA001N, entitled NASA Innovative Advanced Concepts: Phase I Studies, will be available as of January 15, 2013. This solicitation represents continuation of the NASA Innovative Advanced Concepts (NIAC) program, which issued its first solicitation on March 1, 2011. This NRA will solicit multiple studies, each of which will investigate an architecture, mission, or system concept with the potential to enable a great leap in space or aeronautics. NIAC is part of the Space Technology Program in the Office of Chief Technologist. Aerospace architecture, mission, or system concepts proposed for NIAC Phase I studies must be exciting, unexplored, far-term, and credible. Proposals for narrow technology or subsystem development, or incremental or near-term advancement, are explicitly out of scope for this program. Finally, while NIAC encourages daring vision and accepts the accompanying risk, proposals must be technically credible and plausibly implementable." More

A new paper by scientists on NASA's Cassini mission finds that blocks of hydrocarbon ice might decorate the surface of existing lakes and seas of liquid hydrocarbon on Saturn's moon Titan.

An analysis of the first three years of data from NASA's Kepler mission, which already has discovered thousands of potential exoplanets, contains good news for those searching for habitable worlds outside our solar system

Comets trailing wispy tails across the night sky are a beautiful byproduct of our solar system's formation, icy leftovers from 4.6 billion years ago when the planets coalesced from rocky rubble.

In 2011, a months-long blast of energy launched by an enormous black hole almost 11 billion years ago swept past Earth. Using a combination of data from NASA's Fermi Gamma-ray Space Telescope and the National Science Foundation's Very Long Baseline Array (VLBA), the world's largest radio telescope, astronomers have zeroed in on the source of this ancient outburst.

Curiosity Makes First Use of its Brush

NASA's Mars rover Curiosity has completed first-time use of a brush it carries to sweep dust off rocks.

Unlike with some blockbuster films, the sequel to a movie from NASA's Chandra X-ray Observatory is better than the first. This latest movie features a deeper look at a fast moving jet of particles produced by a rapidly rotating neutron star, and may provide new insight into the nature of some of the densest matter in the universe.
