[meteorite-list] Discovery Mission Finalists Could Be Given Second Shot (Titan Mare Explorer, Comet Hopper)
http://www.spacenews.com/article/civil-space/36485discovery-mission-finalists-could-be-given-second-shot Discovery Mission Finalists Could Be Given Second Shot By Brian Berger Space news July 26, 2013 WASHINGTON - U.S. Senate appropriators are attempting to breath new life into one of two deep-space mission proposals that were passed over in the most recent competition under NASA's Discovery-series of cost-capped planetary probes. In a proposed spending bill for 2014, the Senate Appropriations Committee directed NASA to resume design work on one of the Discovery finalists: a lander that would hop on and off a comet racing toward the sun; and a probe that would splash down in one of the large methane-ethane seas on Saturn's largest moon, Titan. In 2010, a total of 28 teams sent NASA proposals for a slew of robotic solar system exploration missions that could be ready to launch by the end of 2016 for no more than $425 million, not including the cost of an Atlas 5 rocket or comparable vehicle. The following year, NASA selected three finalists: the Jet Propulsion Laboratory's Mars-bound Geophysical Monitoring Station, the Johns Hopkins University Applied Physics Laboratory's Titan Mare Explorer (TiME) and the University of Maryland's Comet Hopper. Each team was awarded $3 million to refine their concepts over the next 12 months. Last August, NASA chose the Mars mission proposal - an instrument-laden lander renamed InSight to avoid confusion with the since-canceled Gravity and Extreme Magnetism Small Explorer mission - to proceed toward a 2016 launch. The two runners-up have strong Maryland pedigrees, a point almost certainly not lost on Sen. Barbara Mikulski (D-Md.), who chairs the appropriations panel and led the drafting of the 2014 Commerce, Justice, Science and Related Agencies Appropriations Act (S. 1329), which includes NASA. A report accompanying the bill, approved by the committee July 18, directs NASA to provide additional funding in Discovery to initiate Phase B study activities on an additional Discovery mission from the most recent 2012 announcement of opportunity with the highest scientific value that meets the program's cost cap. University of Maryland researcher Jessica Sunshine, the principal investigator behind the Comet Hopper proposal, quipped that she had a heart attack when she learned that Senate appropriators want to give Comet Hopper and TiME a second shot at becoming full-fledged missions. It was a surprise to me, Sunshine said July 25. Being as objective as I can be - and I realize I don't have a lot of credibility here - I think it's a great idea. Sunshine said Phase B funding, which typically amounts to 10-15 percent of total mission costs, would allow her team to make sure everything you think will work is actually going to work. Phase B is the time when you sit down and really define your technical specifications for everything, she said. No metal is bent; it's still a study, but there are some long lead items that if you don't procure them in Phase B you won't make it. Comet Hopper, which would orbit and land multiple times on Comet Wirtanen as it approaches the sun, would be built by Lockheed Martin Corp. of Bethesda, Md., under the management of NASA's Goddard Space Flight Center in Greenbelt, Md. TiME, a floating lander that would be dropped onto the surface of one of the largest lakes on Titan, was proposed by Ellen Stofan of Gaithersburg, Md.-based Proxemy Research and would be built by the Applied Physics Laboratory in Laurel, Md. TiME's deputy principal investigator, Jonathan Lunine of Cornell University's Center for Radiophysics and Space Research, told SpaceNews he and Stofan are very much encouraged by the language in the Senate bill. TiME is ready to go if and when the Senate language becomes law, he wrote in a July 26 email. Of course, it is all up to the political process, but the seas of Titan await us! Both Comet Hopper and TiME were designed to carry a government-furnished power source known as the Advanced Stirling Radioisotope Generator (ASRG). The plutonium-fueled device, still in development, is expected to be four times more efficient than the current-generation nuclear battery that powers the Mars Curiosity rover, for example. InSight, which was selected at a time when NASA was taking flak for scaling back its contribution to Europe's ExoMars missions, will rely on solar power when it lands near the martian equator in September 2016 to begin a two-year mission to study the red planet's geological evolution. While neither the Comet Hopper nor TiME team would have had to pay for the ASRG itself, NASA required them to set aside $20 million of their $425 million notional mission budgets to pay for environmental compliance, nuclear launch safety approval and related launch services. This $20 million cost was not of course carried by the non-ASRG InSight team and $20 million

[meteorite-list] Around the World in Four Days: NASA Tracks Chelyabinsk Meteor Plume
http://www.nasa.gov/content/goddard/around-the-world-in-4-days-nasa-tracks-chelyabinsk-meteor-plume/ Around the World in Four Days: NASA Tracks Chelyabinsk Meteor Plume Kathryn Hansen NASA's Earth Science News Team Aug. 14, 2013 [Video] A meteor weighing 10,000 metric tons exploded 14 miles above Chelyabinsk, Russia, on Feb. 15, 2013. Unlike similar past events, this time scientists had the sensitive instruments on the Suomi NPP satellite to deliver unprecedented data and help them track and study the meteor plume for months. Atmospheric physicist Nick Gorkavyi missed witnessing an event of the century last winter when a meteor exploded over his hometown of Chelyabinsk, Russia. From Greenbelt, Md., however, NASA's Gorkavyi and colleagues witnessed a never-before-seen view of the atmospheric aftermath of the explosion. Shortly after dawn on Feb. 15, 2013, the meteor, or bolide, measuring 59 feet (18 meters) across and weighing 11,000 metric tons, screamed into Earth's atmosphere at 41,600 mph (18.6 kilometers per second). Burning from the friction with Earth's thin air, the space rock exploded 14.5 miles (23.3 kilometers) above Chelyabinsk. The explosion released more than 30 times the energy from the atom bomb that destroyed Hiroshima. For comparison, the ground-impacting meteor that triggered mass extinctions, including the dinosaurs, measured about 6 miles (10 kilometers) across and released about 1 billion times the energy of the atom bomb. Some of the surviving pieces of the Chelyabinsk bolide fell to the ground. But the explosion also deposited hundreds of tons of dust up in the stratosphere, allowing a NASA satellite to make unprecedented measurements of how the material formed a thin but cohesive and persistent stratospheric dust belt. We wanted to know if our satellite could detect the meteor dust, said Gorkavyi, of NASA's Goddard Space Flight Center in Greenbelt, Md., who led the study, which has been accepted for publication in the journal Geophysical Research Letters. Indeed, we saw the formation of a new dust belt in Earth's stratosphere, and achieved the first space-based observation of the long-term evolution of a bolide plume. Gorkavyi and colleagues combined a series of satellite measurements with atmospheric models to simulate how the plume from the bolide explosion evolved as the stratospheric jet stream carried it around the Northern Hemisphere. About 3.5 hours after the initial explosion, the Ozone Mapping Profiling Suite instrument's Limb Profiler on the NASA-NOAA Suomi National Polar-orbiting Partnership satellite detected the plume high in the atmosphere at an altitude of about 25 miles (40 kilometers), quickly moving east at about 190 mph (more than 300 kph). The day after the explosion, the satellite detected the plume continuing its eastward flow in the jet and reaching the Aleutian Islands. Larger, heavier particles began to lose altitude and speed, while their smaller, lighter counterparts stayed aloft and retained speed - consistent with wind speed variations at the different altitudes. By Feb. 19, four days after the explosion, the faster, higher portion of the plume had snaked its way entirely around the Northern Hemisphere and back to Chelyabinsk. But the plume's evolution continued: At least three months later, a detectable belt of bolide dust persisted around the planet. The scientists' model simulations, based on the initial Suomi NPP observations and knowledge about stratospheric circulation, confirmed the observed evolution of the plume, showing agreement in location and vertical structure. Thirty years ago, we could only state that the plume was embedded in the stratospheric jet stream, said Paul Newman, chief scientist for Goddard's Atmospheric Science Lab. Today, our models allow us to precisely trace the bolide and understand its evolution as it moves around the globe. The full implications of the study remain to be seen. Every day, about 30 metric tons of small material from space encounters Earth and is suspended high in the atmosphere. Even with the addition of the Chelyabinsk debris, the environment there remains relatively clean. Particles are small and sparse, in contrast to a stratospheric layer just below where abundant natural aerosols from volcanoes and other sources collect. Still, with satellite technology now capable of more precisely measuring tiny atmospheric particles, scientists can embark on new studies in high-altitude atmospheric physics. How common are previously unobservable bolide events? How might this debris influence stratospheric and mesospheric clouds? Scientists previously knew that debris from an exploded bolide could make it high into the atmosphere. In 2004, scientists on the ground in Antarctica made a single lidar observation of the plume from a 1,000-ton bolide. But now in the space age, with all of this technology, we can achieve a very different
[meteorite-list] Attempts to Retrieve Meteorite Pieces from Lake Chebarkul
http://siberiantimes.com/science/casestudy/news/visitor-from-outer-space-to-be-hauled-out-of-russian-lake/ Visitor from outer space to be hauled out of Russian lake The Siberian Times 04 August 2013 The fireball sparked panic as it flew over the Ural Mountains, shattering glass in cities, wounding well over 1,000, amid warnings that 'doomsday' had arrived. Now sizeable chunks of this cosmic guest are to be pulled out of Lake Chebarkul, in Chelyabinsk region, where they fell in February this year. They will give scientists a special insight into the space rock that so suddenly and dramatically struck Western Siberia. A large lump of meteorite - perhaps the biggest - is reported resting in silt some 50 metres from the spot it made an icy hole in the murky lake. 'The operation will be held in the muddy waters of the lake in conditions of zero visibility,' reported Itar-Tass, citing Alexander Galich, the regional minister of radiation and ecological security. 'Divers will have to use special equipment. The local authorities will engage professional divers from the regional rescue services and from other specialised organizations.' Sergei Zakharov, of the geography department of Chelyabinsk State Pedagogical University, said: 'We have established jointly with researchers from the Charles University in Prague that after falling into the lake the meteorite struck against the ice from below and only then sank. 'It is not ruled out that it might have broken into pieces'. __ Visit the Archives at http://www.meteorite-list-archives.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list

[meteorite-list] Mars Rover Opportunity Working at Edge of 'Solander'
http://www.jpl.nasa.gov/news/news.php?release=2013-250 Mars Rover Opportunity Working at Edge of 'Solander' Jet Propulsion Laboratory August 14, 2013 Mars Exploration Rover Mission Status Report PASADENA, Calif. - NASA's Mars rover Opportunity is studying the area of contact between a rock layer formed in acidic wet conditions long ago and an even older one that may be from a more neutral wet environment. This geological contact line recording a change in environmental conditions billions of years ago lies at the foot of a north-facing slope, Solander Point, that the rover's operators chose months ago as Opportunity's work area for the coming Martian southern hemisphere winter. Opportunity has survived five Martian winters since it landed on Mars in January 2004. A northern slope would tilt the rover's solar panels toward the winter sun, providing an important boost in available power. Three months ago, the mission began a trek of about 1.5 miles (2.4 kilometers) from an area where Opportunity worked for nearly two years, on Cape York, to reach Solander Point for the winter. We made it, said Opportunity's project scientist, Matt Golombek of NASA's Jet Propulsion Laboratory, Pasadena, Calif. The drives went well, and Opportunity is right next to Solander Point. We know we could be on that north-facing slope with a one-day drive, but we don't need to go there yet. We have time to investigate the contact between the two geological units around the base of Solander Point. Geologists love contacts. Both Cape York and Solander Point are raised segments of the western rim of Endeavour Crater, which is about 14 miles (22 kilometers) in diameter. Between these two raised segments, the ground surface is part of a geological unit called the Burns Formation, which also includes virtually all the rocks Opportunity studied from its landing site in Eagle Crater until its arrival at Cape York two years ago. The Burns Formation includes sulfate-bearing minerals that are evidence of an ancient environment containing sulfuric acid. The geological contact that Opportunity is now investigating is where Burns Formation rocks border older rocks uplifted by the impact that formed Endeavour Crater. From observations by Mars orbiters and from Opportunity's work on Cape York, researchers suspect these older rocks may contain minerals that formed under wet conditions that were not as acidic. The rover is also observing some loose rocks that may have rolled off Solander Point, providing a preview of what Opportunity may find after it climbs onto that rim segment. Based on an analysis of the amount of dust accumulated on the rover's solar panels, the team plans to get Opportunity onto the north-facing slope before mid-December. Daily sunshine for the rover will reach a winter minimum in February 2014. The team expects to keep the rover mobile through the winter. Solander Point offers rock outcrops for the rover to continue studying through the winter months. The twin rovers of NASA's Mars Exploration Rover Project, Opportunity and Spirit, both completed three-month prime missions in April 2004 and began years of bonus, extended missions. Both found evidence of wet environments on ancient Mars. Spirit ceased operations during its fourth Martian winter, in 2010. Opportunity shows symptoms of aging, such as loss of motion in some joints, but continues to accomplish groundbreaking exploration and science.
