Climate modeling requires massive computational power. Until recently, that power required room sized machines with daunting technical and logistic requirements. But new advances in computer design, including hardware and software, continue to facilitate a paradigm shift.
In an effort to broaden and democratize climate research tools, NASA has begun to facilitate the operation of new desktop sized supercomputers, with the goal of making it substantially easier for more researchers to do meaningful work on vital and essential questions for our world.

NASA's challenging mission to explore space and understand the universe and the Earth within it requires the agency to innovatively apply and extend humankind's most advanced capabilities, technologies, and knowledge. High-end computing is one such powerful leading-edge tool.
The mission of NASA's High-End Computing (HEC) Program is to:
• Plan and provision high-end computing systems and services to support NASA's mission needs. Operate and manage these HEC resources for the benefit of agency users, customers, and stakeholders.
• NASA's HEC resources are relied on as an essential and pervasive partner by the breadth of agency science, engineering, and technology activities, enabling rapid advances in insight and dramatically enhancing mission achievements.
Four top-level HEC Program goals will lead to accomplishing the mission and achieving the vision:
• Provide effective production HEC resources and services to enable pervasive, timely, and significant mission impacts.
• Infuse HEC into NASA's scientific and engineering communities.
• Assure preparedness to meet NASAs future modeling, simulation, and analysis needs.
• Ensure that NASA HEC resources and activities are well-managed and wisely used.

► Eclipse over the Temple of Poseidon
The Moon moved to partly block the Sun for a few minutes last week as a partial solar eclipse became momentarily visible across part of planet Earth. In the above single exposure image, meticulous planning enabled careful photographers to capture the partially eclipsed Sun well posed just above the ancient ruins of the Temple of Poseidon in Sounio, Greece.

► Dust Sculptures in the Rosette Nebula
Noted for the common beauty of its overall shape, parts of the Rosette Nebula, also known as NGC 2237, show beauty even when viewed up close. Visible above are globules of dark dust and gas that are slowly being eroded away by the energetic light and winds by nearby massive stars. Left alone long enough, the molecular-cloud globules would likely form stars and planets. The Rosette Nebula spans about 50 light-years across and lies about 4,500 light-years away.

► Watch Jupiter Rotate
What would it be like to coast by Jupiter and watch it rotate? This was just the experience of the New Horizons spacecraft as it approached and flew by Jupiter. Visible above in the extensive atmosphere of the Solar Systems largest planet are bands and belts of light and dark clouds, as well as giant rotating storm systems seen as ovals. The robotic New Horizons spacecraft continues to speed toward the outer Solar System and has recently passed the halfway point between Earth and Pluto.

► NGC 6992: Filaments of the Veil Nebula
Wisps like this are all that remain visible of a Milky Way star. About 7,500 years ago that star exploded in a supernova leaving the Veil Nebula, also known as the Cygnus Loop. At the time, the expanding cloud was likely as bright as a crescent Moon, remaining visible for weeks to people living at the dawn of recorded history. Today, the resulting supernova remnant has faded.

► Dark Sand Cascades on Mars
They might look like trees on Mars, but theyre not. Groups of dark brown streaks have been photographed by the Mars Reconnaissance Orbiter on melting pinkish sand dunes covered with light frost. The image was taken near the North Pole of Mars. At that time, dark sand on the interior of Martian sand dunes became more and more visible as the spring Sun melted the lighter carbon dioxide ice. When occurring near the top of a dune, dark sand may cascade down the dune leaving dark surface streaks streaks that might appear at first to be trees standing in front of the lighter regions, but cast no shadows.

► Eclipses in the Shade
Eclipses are everywhere in this shady scene. The picture was taken on the Indian Ocean atoll island of Ellaidhoo, Maldives, in January 2010, during the longest annular solar eclipse for the next 1,000 years. Tall palm trees provided the shade. Their many crossed leaves created gaps that acted like pinhole cameras, scattering recognizable eclipse images across the white sands of a tropical garden near the beach. From this idyllic location near the centerline of the Moons shadow track, the ring of fire or annular phase of the eclipse lasted about 10 minutes and 55 seconds.

► Dust and the NGC 7771 Group
Some 200 million light-years distant toward the constellation Pegasus, NGC 7771 is the large, edge-on spiral near center, about 75,000 light-years across, with two smaller galaxies just below it. Large spiral NGC 7769 is seen face-on to the right. Galaxies of the NGC 7771 group are interacting, making repeated close passages that will ultimately result in galaxy-galaxy mergers on a cosmic timescale.

► Millennium Annular Solar Eclipse
The Moons shadow raced across planet Earth on January 15. Observers within the central shadow track were able to witness an annular solar eclipse as the Moons apparent size was too small to completely cover the Sun. A visually dramatic ring of fire, the annular phase lasted up to 11 minutes and 8 seconds depending on location, the longest annular solar eclipse for the next 1,000 years.
