shared by Mars Base on 17 Dec 12 - No Cached
  • This UAV is capable of both hover and wing-borne flight, making the delivery and precision emplacement of a payload possible
  • A special robotic arm was designed with the capability of carrying up to 1 pound.
  • developed a low-cost vision system to estimate the target's position relative to the hovering vehicle in real time
  • ...10 more annotations...
  • vision system enables the UAV to search and find the target for the emplacement autonomously and then perform the action
  • Our goal
  • was to show we could quickly develop and integrate the right technology to make this work
  • this technology
  • successfully demonstrated
  • A newly developed stereo vision system that tracks the emplacement target and motion of the robotic arm.
  • The vision system, coupled with global positioning system, controls the arm and V-Bat during emplacement.
  • Control logic to maneuver the vehicle and direct the robotic arm to accurately engage the emplacement target.
  • Vehicle stability with the arm extended 6 feet with a 1-pound payload.
  • Autonomous search and detection of the emplacement target and autonomously emplaced a 1-pound payload

  • GRAIL ends its successful mission by impacting the Moon on December 17, 2012 at approximately 5:27 p.m. EST (22:27 UT).
  • The two spacecraft were placed in an orbit that takes them within a kilometer of the surface, so low that they will hit the side of an unnamed mountain
  • near the north pole
  • ...1 more annotation...
  • Ebb strikes first, followed 24 seconds later by Flow

  • The spot on the lunar surface where NASA intentionally crashed its twin gravity-mapping moon probes
  • Dec. 17) has been named after the late Sally Ride, America's first woman in space
  • Ebb and Flow, slammed into a crater rim near the moon's north pole at 5:28 p.m. EST (2228 GMT)
  • ...2 more annotations...
  • f Sally Ride, who played a key role in Grail's education and outreach efforts
  • Ride had led Grail's MoonKAM project, which allowed schoolkids around the world to select lunar sites for Ebb and Flow to photograph

scibyte75 HiggsBoson

shared by Mars Base on 18 Dec 12 - No Cached
  • t much further analysis is needed to reveal the full details of its identity
  • The next update is scheduled for the spring 2013 conferences
  • for the final word before the LHC resumes running in 2015, we'll probably have to wait some time longer.
  • ...1 more annotation...
  • The latest research findings from the Large Hadron Collider (LHC) at CERN show that the CMS and ATLAS experiments are now reporting that the significance of their observation of the Higgs-like particle is standing close to the 7 sigma level, well beyond the 5 required for a discovery, and that the new particle's properties appear to be consistent with those of a Standard Model Higgs boson.

  • By design, the final resting place was far away from the Apollo landing sites and other historical spots on the moon
  • The Lunar Reconnaissance Orbiter circling the moon will pass over the mountain and attempt to photograph the skid marks left by the washing machine sized-spacecraft as they hit the surface at 3,800 mph
  • the crash site was in darkness, the final act was not visible from Earth.
  • ...1 more annotation...
  • During the primary mission, they flew about 35 miles above the lunar surface. After getting bonus data-collecting time, they lowered their altitude to 14 miles (22 kilometers) above the surface

Mars Science Laboratory: Curiosity Rover Nearing Yellowknife Bay - 0 views

scibyte75 Curiosity

shared by Mars Base on 16 Dec 12 - No Cached
  • The NASA Mars rover Curiosity drove 63 feet (19 meters) northeastward early Monday, Dec. 10, approaching a step down into a slightly lower area called "Yellowknife Bay," where researchers intend to choose a rock to drill.
  • Curiosity ended Monday's drive about 30 percent shorter than planned for the day when it detected a slight difference between two calculations of its tilt, not an immediate risk, but a trigger for software to halt the drive as a precaution
  • Curiosity is approaching a lip where it will descend about 20 inches (half a meter) to Yellowknife Bay. The rover team is checking carefully for a safe way down. Yellowknife Bay is the temporary destination for first use of Curiosity's rock-powdering drill, before the mission turns southwestward for driving to its main destination on the slope of Mount Sharp.

  • The robotic arm on NASA's Mars rover Curiosity held the rover's Mars Hand Lens Imager (MAHLI) camera in more than 50 positions in one day to generate a single scene combining all the images, creating a high-resolution, full-color portrait of the rover itself.
  • A larger version of the previously released self-portrait is now available online, along with an animation video showing how it was taken, and a practice self-portrait taken earlier by Curiosity's test-rover double on Earth
