[meteorite-list] Use of Curiosity Rover Arm Expected to Resume in a Few Days
http://www.jpl.nasa.gov/news/news.php?feature=4504 Use of Rover Arm Expected to Resume in a Few Days Jet Propulsion Laboratory March 6, 2015 Mission Status Report Managers of NASA's Curiosity Mars rover mission expect to approve resumption of rover arm movements as early as next week while continuing analysis of what appears to be an intermittent short circuit in the drill. A fluctuation in current on Feb. 27 triggered a fault-protection response that immediately halted action by the rover during the mission's 911th Martian day, or sol. Since then, the rover team has avoided driving Curiosity or moving the rover's arm, while engineers have focused on diagnostic tests. Science observations with instruments on the rover's mast have continued, along with environmental monitoring by its weather station. "Diagnostic testing this week has been productive in narrowing the possible sources of the transient short circuit," said Curiosity Project Manager Jim Erickson of NASA's Jet Propulsion Laboratory, Pasadena, California. "The most likely cause is an intermittent short in the percussion mechanism of the drill. After further analysis to confirm that diagnosis, we will be analyzing how to adjust for that in future drilling." The sample-collection drill on Curiosity's robotic arm uses both rotation and hammering, or percussion, to penetrate into Martian rocks and collect pulverized rock material for delivery to analytical instruments inside the rover. The short on Sol 911 occurred while the rover was transferring rock-powder sample from the grooves of the drill into a mechanism that sieves and portions the powder. The percussion action was in use, to shake the powder loose from the drill. Engineers received results Thursday, March 5, from a test on Curiosity that similarly used the drill's percussion action. During the third out of 180 up-and-down repeats of the action, an apparent short circuit occurred for less than one one-hundredth of a second. Though small and fleeting, it would have been enough to trigger the fault protection that was active on Sol 911 under the parameters that were in place then. The rover team plans further testing to characterize the intermittent short before the arm is moved from its present position, in case the short does not appear when the orientation is different. After those tests, the team expects to finish processing the sample powder that the arm currently holds and then to deliver portions of the sample to onboard laboratory instruments. Next, Curiosity will resume climbing Mount Sharp. NASA's Mars Science Laboratory Project is using Curiosity to assess ancient habitable environments and major changes in Martian environmental conditions. JPL, a division of the California Institute of Technology in Pasadena, built the rover and manages the project for NASA's Science Mission Directorate in Washington.

[meteorite-list] Dawn Becomes First to Orbit a Dwarf Planet
http://www.jpl.nasa.gov/news/news.php?feature=4503 NASA Spacecraft Becomes First to Orbit a Dwarf Planet Jet Propulsion Laboratory March 6, 2016 NASA's Dawn spacecraft has become the first mission to achieve orbit around a dwarf planet. The spacecraft was approximately 38,000 miles (61,000 kilometers) from Ceres when it was captured by the dwarf planet's gravity at about 4:39 a.m. PST (7:39 a.m. EST) Friday. Mission controllers at NASA's Jet Propulsion Laboratory in Pasadena, California received a signal from the spacecraft at 5:36 a.m. PST (8:36 a.m. EST) that Dawn was healthy and thrusting with its ion engine, the indicator Dawn had entered orbit as planned. "Since its discovery in 1801, Ceres was known as a planet, then an asteroid and later a dwarf planet," said Marc Rayman, Dawn chief engineer and mission director at JPL. "Now, after a journey of 3.1 billion miles (4.9 billion kilometers) and 7.5 years, Dawn calls Ceres, home." In addition to being the first spacecraft to visit a dwarf planet, Dawn also has the distinction of being the first mission to orbit two extraterrestrial targets. From 2011 to 2012, the space-craft explored the giant asteroid Vesta, delivering new insights and thousands of images from that distant world. Ceres and Vesta are the two most massive residents of our solar system's main asteroid belt between Mars and Jupiter. The most recent images received from the spacecraft, taken on March 1, show Ceres as a crescent, mostly in shadow because the spacecraft's trajectory put it on a side of Ceres that faces away from the sun until mid-April. When Dawn emerges from Ceres' dark side, it will deliver ever-sharper images as it spirals to lower orbits around the planet. "We feel exhilarated," said Chris Russell, principal investigator of the Dawn mission at the University of California, Los Angeles (UCLA). "We have much to do over the next year and a half, but we are now on station with ample reserves, and a robust plan to obtain our science objectives." Dawn's mission is managed by JPL for NASA's Science Mission Directorate in Washington. Dawn is a project of the directorate's Discovery Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. UCLA is responsible for overall Dawn mission science. Orbital ATK Inc., in Dulles, Virginia, designed and built the spacecraft. The German Aerospace Center, Max Planck Institute for Solar System Research, Italian Space Agency and Italian National Astrophysical Institute are international partners on the mission team.

[meteorite-list] Classification Correction- Gold Basin
Hello List, For those that were paying attention to the Gold Basin thread, I made a mistake and sent the classification details for the wrong meteorite! I had several stones classified at the same time and I copied the write up for a different L6, not GB. Here's the correct info. UCLA (Rubin, Breen) specimen 1938, received October 2, 2014, 1 piece, 66.2 g L6 S5W2 olivine: Fa 23.3±0.2 (n=11); low-Ca pyroxene: Fs20.2±0.7 Wo1.0±0.2 (n=15) The rock exhibits strong mosacisim and contains maskelynite. Polycrystalline troilite is present. Some metal grains contain small, irregularly shaped troilite grains within them. Thanks to everyone for the congrat's and kind words.

[meteorite-list] Ceres and Meteorites?
Hello MikeG and List, MikeG inquires: "Has Ceres ever been connected to any type of meteorite?" GEHRELS TOM (1979) Asteroids (The University of Arizona Press, Tucson, Arizona, 1181 pp., Infrared Spectral Reflectances of Asteroid Surfaces, H.P. Larson and G.J. Veeder, pp. 724-744, p. 735): "... the surface of Ceres is a hydrated mineral assemblage that, if restricted to comparisons with meteorites, most closely resembles Type C2 carbonaceous chondrites...The comparison of Ceres' surface with primitive meteoritic matter is most consistent with the spectral data."

Re: [meteorite-list] Ceres and Meteorites?
Hi Mike: Two short answers: 1. Closest to the CI chondrites 2. Probably no meteorites from Ceres: nothing looks quite like it and I think it is not near a resonance that would easily ship chunks of Ceres to Earth (unlike Vesta).
