[meteorite-list] NASA Space Launch System Core Stage Moves From Concept to Design
June 21, 2012 Trent J. Perrotto Headquarters, Washington 202-358-0321 trent.j.perro...@nasa.gov Jennifer Stanfield Marshall Space Flight Center, Huntsville, Ala. 256-544-0034 jennifer.m.stanfi...@nasa.gov RELEASE: 12-211 NASA SPACE LAUNCH SYSTEM CORE STAGE MOVES FROM CONCEPT TO DESIGN HUNTSVILLE, Ala. -- The nation's space exploration program is taking a critical step forward with a successful major technical review of the core stage of the Space Launch System (SLS), the rocket that will take astronauts farther into space than ever before. The core stage is the heart of the heavy-lift launch vehicle. It will stand more than 200 feet (61 meters) tall with a diameter of 27.5 feet (8.4 meters). NASA's Marshall Space Flight Center in Huntsville, Ala., hosted a comprehensive review. Engineers from NASA and The Boeing Co. of Huntsville presented a full set of system requirements, design concepts and production approaches to technical reviewers and the independent review board. "This meeting validates our design requirements for the core stage of the nation's heavy-lift rocket and is the first major checkpoint for our team," said Tony Lavoie, manager of the SLS Stages Element at Marshall. "Getting to this point took a lot of hard work, and I'm proud of the collaboration between NASA and our partners at Boeing. Now that we have completed this review, we go from requirements to real blueprints. We are right on track to deliver the core stage for the SLS program." The core stage will store liquid hydrogen and liquid oxygen to feed the rocket's four RS-25 engines, all of which will be former space shuttle main engines for the first few flights. The SLS Program has an inventory of 16 RS-25 flight engines that successfully operated for the life of the Space Shuttle Program. Like the space shuttle, SLS also will be powered initially by two solid rocket boosters on the sides of the launch vehicle. The SLS will launch NASA's Orion spacecraft and other payloads, and provide an entirely new capability for human exploration beyond low Earth orbit. Designed to be safe, affordable and flexible for crew and cargo missions, the SLS will continue America's journey of discovery and exploration to destinations including nearby asteroids, Lagrange points, the moon and ultimately, Mars. "This is a very exciting time for the country and NASA as important achievements are made on the most advanced hardware ever designed for human spaceflight," said William Gerstenmaier, associate administrator for the Human Exploration Operations Mission Directorate at NASA Headquarters in Washington. "The SLS will power a new generation of exploration missions beyond low Earth orbit and the moon, pushing the frontiers of discovery forward. The innovations being made now, and the hardware being delivered and tested, are all testaments to the ability of the U.S. aerospace workforce to make the dream of deeper solar system exploration by humans a reality in our lifetimes." The first test flight of NASA's Space Launch System, which will feature a configuration for a 77-ton (70-metric-ton) lift capacity, is scheduled for 2017. As SLS evolves, a two-stage launch vehicle configuration will provide a lift capability of 143 tons (130 metric tons) to enable missions beyond low Earth orbit and support deep space exploration. Boeing is the prime contractor for the SLS core stage, including its avionics. The core stage will be built at NASA's Michoud Assembly Facility in New Orleans using state-of-the-art manufacturing equipment. Marshall manages the SLS Program for the agency. Across the SLS Program, swift progress is being made on several elements. The J-2X upper-stage rocket engine, developed by Pratt & Whitney Rocketdyne for the future two-stage SLS, is being tested at Stennis Space Center in Mississippi. The prime contractor for the five-segment solid rocket boosters, ATK of Brigham City, Utah, has begun processing its first SLS hardware components in preparation for an initial qualification test in 2013.

MARS RECONNAISSANCE ORBITER HIRISE IMAGES June 20, 2012 o Rough Surfaces in Deuteronilus Mensae http://hirise.lpl.arizona.edu/ESP_025174_2245 The objective of this observation is to examine what may be formerly ice-rich terrain that has just lost ice to the atmosphere. o Exploring Antoniadi Crater http://hirise.lpl.arizona.edu/ESP_025331_2005 Antoniadi Crater was identified, even prior to the MRO mission, as a likely ancient lake (now dry) that was supplied by both surface water and ground water. o Ridges in Meridiani Planum http://hirise.lpl.arizona.edu/ESP_025386_1800 When terrain gets squeezed by geologic forces deep rocks sometimes break and get pushed upwards forming raised wrinkles on the surface. o Colorful Layers in Nili Fossae http://hirise.lpl.arizona.edu/ESP_026992_2025 This enhanced-color version of the central part of the HiRISE image shows colorful layers that may contain carbonate minerals. All of the HiRISE images are archived here: http://hirise.lpl.arizona.edu/ Information about the Mars Reconnaissance Orbiter is online at http://www.nasa.gov/mro. The mission is managed by NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology, for the NASA Science Mission Directorate, Washington, D.C. Lockheed Martin Space Systems, of Denver, is the prime contractor and built the spacecraft. HiRISE is operated by the University of Arizona. Ball Aerospace and Technologies Corp., of Boulder, Colo., built the HiRISE instrument. __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] stability of morasko iron
Good evening list. It has been a while,but Im still around. Hey of all the well known iron meteorites out there,like sikhote-alin,campo,mundrabilla,henbury etc. How stable is the morasko iron? I have never owned one and I am seeing them more available. I need to know before one comes to chicago. Any help will be appreciated. Also today I went for my 6 month skin cancer check-up and I am good for another 6 months. Good feeling to have with the weekend coming. All I need is a job. Have a great eveing all. Steve R. Anold, chicago, ill. Hi Steve Answering Your question I must say that there are more rumors about rusting of Morasko than truth. Its not desert iron so as every iron it CAN rust but it depends of few things. Place of find (sand or mud) and also how it was prepared and treated after the find. I have several large cut specimens that dont rust for years. I dont see a reason to be affraid of this meteorite. Its not ba low quality campo or nantan. If uncut its easy to preserve in good condition. If cut I rather sugest larger specimens than small individuals, becouse small rust more often. But this rule is the same to many other meteorites. This will not change into dust after several months. Morasko is NOT a ruster. -[ MARCIN CIMALA ]-[ I.M.C.A.#3667 ]- http://www.Meteoryty.pl marcin(at)meteoryty.pl http://www.PolandMET.com marcin(at)polandmet.com http://www.Gao-Guenie.com GSM: +48 (793) 567667 [ Member of Polish Meteoritical Society ] __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list Sent from my Verizon Wireless BlackBerry __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
