    Explanation: Have you ever seen the night sky change? It does -- sometimes in beautiful and unexpected ways. To see it, though, usually requires patience. The above award winning video shows several of the possible changes in dramatic fashion with a time lapse video. Visible are sunset-illuminated clouds moving, stars of vivid colors rising, the long tail of a Comet Lovejoy rising, bright satellites crossing, a meteor exploding, a distant lightning storm approaching, skyscapes including the Magellanic Clouds rotating, and a fisheye sky rotating while the foreground becomes illuminated by moonlight. Frequently featuring an artistic human sculpture in the foreground...

    Enlarge Image On the ground. One of the first images snapped by Curiosity, sent within minutes after it touched down, shows the rover's own shadow. Credit: NASA/JPL-Caltech It all worked. The 500,000 lines of computer code went off without a glitch. The 76 onboard explosive devices popped off in sequence to the microsecond, throwing valves and cutting loose tether lines. So Curiosity rover's 7 minutes of terror had the happiest of endings. At 1:37 a.m. Eastern Daylight Time, word came down: "Touchdown confirmed. We're safe on Mars." Signals from Curiosity, followed within minutes by the first crude images of...

    Not smashing itself to smithereens was only one of Curiosity’s achievements in the NASA rover’s first day on Mars. It also hit the bull’s-eye and did a first bit of science. Credit: NASA/JPL-Caltech Curiosity on its Way. From 340 kilometers away, the HiRISE camera on the Mars Reconnaissance Orbiter caught the Curiosity rover inside its entry vehicle dangling from its parachute. The chute had been ejected from the entry vehicle by an explosive charge after atmospheric drag had slowed it to Mach 2. The descent vehicle with the rover tucked inside would soon drop out to fire its retrorockets. Credit:...

    The live stream of NASA's Curiosity rover landing garnered more interest than primetime Sunday television, Ustream says. A spokesperson told Mashable that 3.2 million people in total had checked the stream at some point during the landing, with a peak of 500,000 people watching at the same time. That's higher than the estimated viewing numbers for CNN during Sunday primetime, which came in at 426,000, or MSNBC, which had an audience of 365,000 viewers over age two. Ustream's peak audience was lower only than that of Fox, which had an audience of 803,000.

    Explanation: A wheel attached to NASA's Curiosity rover is firmly on the martian surface in this early picture from the Mars Science Laboratory mission, captured after a successful landing on August 5, 2012 at 10:32pm (PDT). Seen at the lower right of a Hazard Avoidance Camera fisheye wide-angle image, the rover's left rear wheel is 50 centimeters (about 20 inches) in diameter. Part of a spring hinge for the camera's dust cover is just visible in the right corner, while at the upper left is part of the rover's RTG power source. Looking into the Sun across the rock stewn...

    This image taken by NASA's Curiosity shows what lies ahead for the rover -- its main science target, Mount Sharp. The rover's shadow can be seen in the foreground, and the dark bands beyond are dunes. Rising up in the distance is the highest peak Mount Sharp at a height of about 3.4 miles, taller than Mt. Whitney in California. The Curiosity team hopes to drive the rover to the mountain to investigate its lower layers, which scientists think hold clues to past environmental change. This image was captured by the rover's front left Hazard-Avoidance camera at full resolution...

    NASA's most advanced Mars rover Curiosity has landed on the Red Planet. The one-ton rover, hanging by ropes from a rocket backpack, touched down onto Mars Sunday to end a 36-week flight and begin a two-year investigation. The Mars Science Laboratory (MSL) spacecraft that carried Curiosity succeeded in every step of the most complex landing ever attempted on Mars, including the final severing of the bridle cords and flyaway maneuver of the rocket backpack.

In a show of technological wizardry, the robotic explorer Curiosity blazed through the pink skies of Mars, steering itself to a gentle landing inside a giant crater for the most ambitious dig yet into the red planets past. Cheers and applause echoed through the NASA Jet Propulsion Laboratory late Sunday after the most high-tech interplanetary rover ever built signaled it had survived a harrowing plunge through the thin Mars atmosphere.

    PASADENA, Calif., Aug 5 (Reuters) - The Mars rover Curiosity, on a quest for signs the Red Planet once hosted the building blocks of life, streaked into the home stretch of its eight-month voyage on Sunday nearing a make-or-break landing attempt NASA calls its most challenging ever. Curiosity, the first full-fledged mobile science laboratory ever sent to a distant world, was scheduled to touch down inside a vast, ancient impact crater on Sunday at 10:31 p.m. Pacific time (1:31 a.m. EDT on Monday/0531 GMT on Monday). Mission control engineers at the Jet Propulsion Laboratory near Los Angeles acknowledge that delivering...

  • Mars: A New Hope

    NASAs most ambitious Mars probe is set to land late today (or early tomorrow, depending where you live). NASA is one of the few government programs that actually invests in a major and important industry that supports high-tech jobs and science and technology advancement. However, the geniuses in Washington has been throwing NASA under the bus as of late. Theyd rather bailout unsuccessful ventures. But I digress. At least NASA is finally relying more on the commercialization of space.

    Explanation: Next week at this time, there may be an amazing new robotic explorer on Mars. Or there may be a new pile of junk. It all likely depends on many things going correctly in the minutes after the Mars Science Laboratory mission arrives at Mars and attempts to deploy the Curiosity rover from orbit. Arguably the most sophisticated landing yet attempted on the red planet, consecutive precision events will involve a heat shield, a parachute, several rocket maneuvers, and the automatic operation of an unusual device called a Sky Crane. These "Seven Minutes of Terror" -- depicted in the...

    Explanation: What created this unusual hole in Mars? The hole was discovered by chance on images of the dusty slopes of Mars' Pavonis Mons volcano taken by the HiRISE instrument aboard the robotic Mars Reconnaissance Orbiter currently circling Mars. The hole appears to be an opening to an underground cavern, partly illuminated on the image right. Analysis of this and follow-up images revealed the opening to be about 35 meters across, while the interior shadow angle indicates that the underlying cavern is roughly 20 meters deep. Why there is a circular crater surrounding this hole remains a topic of speculation,...

    Explanation: What did you do over your winter vacation? If you were the Opportunity rover on Mars, you spent four months of it stationary and perched on the northern slope of Greeley Haven -- and tilted so that your solar panels could absorb as much sunlight as possible. During its winter stopover, the usually rolling robot undertook several science activities including snapping over 800 images of its surroundings, many of which have been combined into this 360-degree digitally-compressed panorama and shown in exaggerated colors to highlight different surface features. Past tracks of Opportunity can be seen toward the left, while...

    Science fiction author Ray Bradbury sits in front of a photo of Mars, presented to him during an 83rd birthday party in his honor on Aug. 23, 2003. Ray Bradbury, master of the sci-fi fantasy and author of Fahrenheit 451, died Tuesday at 91.The man who chronicled dystopian societies had strong political beliefs and spoke as darkly about contemporary politics as he did about burning books. "I think our country is in need of a revolution," the Los Angeles Times quoted him as saying in 2010. "There is too much government today. We've got to remember the government should be...
