Re: [meteorite-list] An annual meteorite gathering
Sounds a good event Edwin...wish I could make it...hope it raises plenty for the cause. Perhaps one daykeep us informed each time.

For over ten years, we have held fun, successful fundraising banquets, sales and auctions to raise money to support the work done at C.M.L. (Cascadia Meteorite Laboratory). In the early years, the events were held here at my home featuring wonderful steaks, salmon and vegetarian on the grill. The wine and beer flowed endlessly in an effort to warm up the bidding. The auctions have always been great fun. Many of you may know our auctioneer Peter Abrahams. He is very well known in Astronomy circles and a long time meteorite collector. Peter handles the auction in a unique, intellectual and entertaining fashion. Your guaranteed to enjoy his style. The CML meteorite event quickly outgrew my home and has moved to the university. Just as CML has taken on a life of its own and grown into a substantial institution, we hope that this event will grow in size. This is an invitation to all members of the international meteorite community: researchers, curators, educators, dealers, hunters and collectors. In the future we hope to have a large vendor area, displays and lectures, food, drink, friends, trading, auction and field trips to places like our local active volcano (Mt St. Helens) and the Columbia Gorge. For you beer lovers, Portland is referred to as the microbrewery capital of the world! If you wish to be one of the pioneers and attend the first of this new era of CML events, please contact us through the link above. There will be selling tables for dealers who wish to attend this year's Spring 2015 CML event. Please support the lab with a visit to the beautiful Northwest and Portland, the river city!

[meteorite-list] Planned Maneuver Further Extends MESSENGER Orbital Operations
http://messenger.jhuapl.edu/news_room/details.php?id=278 MESSENGER Mission News April 3, 2015 Planned Maneuver Further Extends MESSENGER Orbital Operations MESSENGER mission controllers at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Md., conducted a maneuver yesterday to raise the spacecraft's minimum altitude sufficiently to extend orbital operations and further delay the probe's inevitable impact onto Mercury's surface. The previous maneuver, completed on March 18, raised MESSENGER to an altitude at closest approach from 11.6 kilometers (7.2 miles) to 34.4 kilometers (21.4 miles) above the planet's surface. Because of progressive changes to the orbit over time in response to the gravitational pull of the Sun, the spacecraft's minimum altitude continued to decrease. At the time of yesterday's maneuver, MESSENGER was in an orbit with a closest approach of 5.5 kilometers (3.4 miles) above the surface of Mercury. With a velocity change of 2.96 meters per second (6.63 miles per hour), four of the spacecraft's 12 smallest monopropellant thrusters nudged the spacecraft to an orbit with a closest approach altitude of 27.5 kilometers (17.1 miles). This maneuver also increased the spacecraft's speed relative to Mercury at the maximum distance from Mercury, adding about 1.2 minutes to the spacecraft's eight-hour, 17.6-minute orbit period. The second orbit-correction maneuver (OCM) in MESSENGER's low-altitude hover campaign, also called the extension of the second extended mission, OCM-14 is the first propulsive course correction since December 2006 to use the two small thrusters that point sunward from the sunshade center panel. This view shows MESSENGER's orientation at the start of the maneuver. MESSENGER was 200.6 million kilometers (124.6 million miles) from Earth when the 6.7-minute maneuver began at about 4:30 p.m. EDT. Mission controllers at APL verified the start of the maneuver 11.2 minutes later, after the first signals indicating spacecraft thruster activity reached NASA's Deep Space Network tracking station in Goldstone, Calif. The next maneuver, on April 6, will again raise the spacecraft's minimum altitude, allowing scientists to continue to collect images and data from MESSENGER's instruments. The 3.8 days between OCM-14 and OCM-15 will be the shortest time between any two MESSENGER maneuvers. - MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) is a NASA-sponsored scientific investigation of the planet Mercury and the first space mission designed to orbit the planet closest to the Sun. The MESSENGER spacecraft was launched on August 3, 2004, and entered orbit about Mercury on March 18, 2011, to begin a yearlong study of its target planet. MESSENGER's first extended mission began on March 18, 2012, and ended one year later. MESSENGER is now in a second extended mission, which is scheduled to conclude in March 2015. Dr. Sean C. Solomon, the Director of Columbia University's Lamont-Doherty Earth Observatory, leads the mission as Principal Investigator. The Johns Hopkins University Applied Physics Laboratory built and operates the MESSENGER spacecraft and manages this Discovery-class mission for NASA. __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com https://pairlist3.pair.net/mailman/listinfo/meteorite-list

[meteorite-list] MRO Team Returning Mars Orbiter to Duty After Computer Swap
http://www.jpl.nasa.gov/news/news.php?feature=4537 Team Returning Orbiter to Duty After Computer Swap Jet Propulsion Laboratory April 2, 2015 Mission Status Report NASA's Mars Reconnaissance Orbiter, at Mars since 2006, made an unplanned switch on Wednesday from one main computer to a redundant one onboard, triggering a hiatus in planned activities. Sensing the computer swap, the orbiter put itself into a precautionary safe standby mode. It remained healthy, in communication and fully powered. The mission's operations team expects the Mars Reconnaissance Orbiter to resume full duty within a few days, including communication relays and science observations. The orbiter has experienced this type of unplanned computer swap six times previously, starting in 2007 and including two occasions in 2014. We never quite know when it's going to happen, but we know what to do when it does, said Reid Thomas, mission manager for Mars Reconnaissance Orbiter at NASA's Jet Propulsion Laboratory, Pasadena, California. Shifts between the spacecraft's redundant Side A and Side B main computers leave a clear signature that enables the team to quickly diagnose what happened and send commands beginning the process of restoring the orbiter to full operations. The latest swap put the spacecraft onto the Side B computer. NASA's Mars Reconnaissance Orbiter entered orbit around the Red Planet on March 10, 2006. Since then, it has returned more data than all other past and current interplanetary missions combined, with a current tally of 249 terabits. The mission met all its science goals in a two-year primary science phase. Four extensions, the latest beginning in 2014, have added to the science returns. The longevity of the mission has given researchers tools to study seasonal and longer-term changes on the Mars. Among other current activities, the orbiter is examining possible landing sites for future missions to Mars and relaying communications to Earth from NASA's two active Mars rovers. JPL, a division of the California Institute of Technology, Pasadena, manages the Mars Reconnaissance Orbiter for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems, Denver, built the orbiter and collaborates with JPL to operate it.
