[meteorite-list] New Horizons: To Boldly Go On, In the Service of Exploration (2014 MU69)
http://pluto.jhuapl.edu/News-Center/PI-Perspectives.php?page=piPerspective_04_14_2016 April 14, 2016 The PI's Perspective: To Boldly Go On, In the Service of Exploration New Horizons is healthy and has just last month completed the halfway point in its long download of 50-plus gigabits of Pluto system data that we collected last summer. We expect the download to continue through October or November of this year, with more data coming to the ground virtually every week until then. And in July we'll conduct a final Pluto flyby calibration of all seven scientific instruments aboard New Horizons. Our most recent scientific publications appeared in Science magazine last month - a series of five massive scientific reports detailing discoveries made about Pluto system geology, surface compositions, atmospheres, plasma science, and Pluto's small moons. This was the third time the flight of New Horizons has made the cover of Science! This week, though, we completed and turned in our proposal to NASA to continue the exploration by New Horizons. The proposed effort covers another almost two billion miles of space, lasting until 2021, and includes another close flyby, in 2019. NASA will carefully evaluate this proposal for funding and let us know the outcome by June or July. I'm so excited about what we proposed that I thought I'd write about that "extended mission" in this installment of the New Horizons PI Perspective, so you can learn our plans too. Extending the Voyage We call this mission to explore the Kuiper Belt (KB) "KEM" for KB Extended Mission. The centerpiece of the KEM is the close flyby of an ancient Kuiper Belt object (KBO) called 2014 MU69 on Jan 1, 2019 - yep, on New Year's Day! The planned flyby will approach MU69 to about 1,900 miles (3,000 kilometers), which is about four times closer than we flew past Pluto. Consequently, imaging and compositional mapping spectroscopy resolutions are all expected to be even better than what we achieved at the Pluto system! We discovered 2014 MU69 (or MU69, for short) in a dedicated search for possible extended mission flyby targets that we conducted in 2014, using the Hubble Space Telescope. MU69 is about 21 to 40 kilometers across, which makes it about 1,000 times more massive than comet 67P that Rosetta is orbiting but about 500,000 times less massive than Pluto. This places it in a key intermediate size regime to better understand planetary accretion. And given its 4-plus-billion-year existence in cold storage so far from the sun, MU69 will be the most pristine object ever visited by any space mission. With NASA's concurrence, we fired the engines on New Horizons late last year to target this flyby before it cost too much fuel - which would have happened had we waited. In late 2015, with NASA's concurrence, New Horizons was targeted to make a flyby of an ancient Kuiper Belt object a billion miles beyond Pluto, with closest approach planned for Jan. 1, 2019. New Horizons will use all seven of its scientific instruments to explore MU69. The encounter will include detailed global and high-resolution mapping, including color mapping. It will also include compositional mapping, searches for moons of MU69, studies of its surface properties, and searches for an atmosphere. If KEM is approved, flyby operations would begin about 100 days out, in late September 2018 (just 2 years from now!) and continue through the first week of 2019, after closest approach. MU69 data downlink will take 20 months, until late 2020. Some of the attributes of our flyby target (2104 MU69) and our preliminary flyby plans are summarized here. [Table] If I do say so myself, the flyby of MU69 would be a landmark event, shattering all distance records for deep space exploration, and yielding an impressive scientific bounty. However, the New Horizons extended mission we proposed to NASA is much more than just a close flyby of MU69. It also aggressively exploits New Horizons as an observation platform in the Kuiper Belt, capable of studying many other KBOs and the space environment in which they orbit. KEM's other scientific objectives are to: * Make distant flyby observations of about 20 other KBOs during 2016-2020, determining their shapes, satellite populations and surface properties - something no other mission or ground-based telescope can. * Make sensitive searches for rings around a wide variety of KBOs during 2016-2020. * Conduct a heliospheric transect of the Kuiper Belt - making nearly continuous plasma, dust and neutral gas observations from 2016 to 2021, when the spacecraft reaches 50 astronomical units (AU) from the sun. * Potentially conduct astrophysical cruise science in 2020 and 2021, after the MU69 flyby, if NASA desires.

[meteorite-list] Cassini Spacecraft Samples Interstellar Dust
http://www.jpl.nasa.gov/news/news.php?feature=6421 Saturn Spacecraft Samples Interstellar Dust Jet Propulsion Laboratory April 14, 2016 NASA's Cassini spacecraft has detected the faint but distinct signature of dust coming from beyond our solar system. The research, led by a team of Cassini scientists primarily from Europe, is published this week in the journal Science. Cassini has been in orbit around Saturn since 2004, studying the giant planet, its rings and its moons. The spacecraft has also sampled millions of ice-rich dust grains with its cosmic dust analyzer instrument. The vast majority of the sampled grains originate from active jets that spray from the surface of Saturn's geologically active moon Enceladus. But among the myriad microscopic grains collected by Cassini, a special few -- just 36 grains -- stand out from the crowd. Scientists conclude these specks of material came from interstellar space -- the space between the stars. Alien dust in the solar system is not unanticipated. In the 1990s, the ESA/NASA Ulysses mission made the first in-situ observations of this material, which were later confirmed by NASA's Galileo spacecraft. The dust was traced back to the local interstellar cloud: a nearly empty bubble of gas and dust that our solar system is traveling through with a distinct direction and speed. "From that discovery, we always hoped we would be able to detect these interstellar interlopers at Saturn with Cassini. We knew that if we looked in the right direction, we should find them," said Nicolas Altobelli, Cassini project scientist at ESA (European Space Agency) and lead author of the study. "Indeed, on average, we have captured a few of these dust grains per year, travelling at high speed and on a specific path quite different from that of the usual icy grains we collect around Saturn." The tiny dust grains were speeding through the Saturn system at over 45,000 mph (72,000 kilometers per hour), fast enough to avoid being trapped inside the solar system by the gravity of the sun and its planets. "We're thrilled Cassini could make this detection, given that our instrument was designed primarily to measure dust from within the Saturn system, as well as all the other demands on the spacecraft," said Marcia Burton, a Cassini fields and particles scientist at NASA's Jet Propulsion Laboratory in Pasadena, California, and a co-author of the paper. Importantly, unlike Ulysses and Galileo, Cassini was able to analyze the composition of the dust for the first time, showing it to be made of a very specific mixture of minerals, not ice. The grains all had a surprisingly similar chemical make-up, containing major rock-forming elements like magnesium, silicon, iron and calcium in average cosmic proportions. Conversely, more reactive elements like sulfur and carbon were found to be less abundant compared to their average cosmic abundance. "Cosmic dust is produced when stars die, but with the vast range of types of stars in the universe, we naturally expected to encounter a huge range of dust types over the long period of our study," said Frank Postberg of the University of Heidelberg, a co-author of the paper and co-investigator of Cassini's dust analyzer. Stardust grains are found in some types of meteorites, which have preserved them since the birth of our solar system. They are generally old, pristine and diverse in their composition. But surprisingly, the grains detected by Cassini aren't like that. They have apparently been made rather uniform through some repetitive processing in the interstellar medium, the researchers said. The authors speculate on how this processing of dust might take place: Dust in a star-forming region could be destroyed and recondense multiple times as shock waves from dying stars passed through, resulting in grains like the ones Cassini observed streaming into our solar system. "The long duration of the Cassini mission has enabled us to use it like a micrometeorite observatory, providing us privileged access to the contribution of dust from outside our solar system that could not have been obtained in any other way," said Altobelli. The Cassini-Huygens mission is a cooperative project of NASA, ESA and the Italian Space Agency. JPL, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate in Washington. The Cosmic Dust Analyzer is supported by the German Aerospace Center (DLR); the instrument is managed by the University of Stuttgart, Germany.

[meteorite-list] Mars Rover Opportunity Update: April 6-11, 2016
http://mars.nasa.gov/mer/mission/status.html#opportunity OPPORTUNITY UPDATE: Rover Mini-Walkabout to Find Clay Mineral Continues - sols 4338-4343, April 06, 2016-April 11, 2016: Opportunity is exploring the south side of 'Marathon Valley' located on the rim of Endeavour crater. The objective is to identify specific outcrops for evidence of clay minerals, so Opportunity is conducting a mini-'walkabout' in regions that show evidence for clay minerals seen from orbit. The plan is to quickly survey a large region with imagery and then identify surface targets of interest for further in-situ (contact) investigation. At each drive location on the walkabout, the rover collects extensive Navigation Camera (Navcam) and Panoramic Camera (Pancam) panoramas plus targeted multi-filter (color) Pancam panoramas. Energy levels have been very good, so the rover was able to stay up late and collect an atmospheric argon measurement with the Alpha Particle X-ray Spectrometer (APXS) on Sol 4338 (April 6, 2016), after spending the day collecting a multi-frame Pancam panorama. The previous few drives had indicated an elevation in the right-front wheel current. Some of that is explained by the steep terrain the rover is climbing. The team sequenced a set of 'cleat cams' (sub-framed Hazardous Camera images) of the front wheels on Sol 4339 (April 7, 2016), to make sure there were no small rocks that might be fouling the wheels. The wheels were found to be clear of any rocks. On Sol 4340 (April 8, 2016), a set of Microscopic Imager (MI) sky flats (calibration images) were collected using the robotic arm to point the MI up at the diffuse sky. More Pancam and Navcam panoramic imaging was collected at this location. On the next sol, Opportunity drove about 45 feet (13.7 meters) to the southwest to set up for the next imagining station. Over the next two sols the rover collected extensive Pancam and Navcam imagery. As of Sol 4343 (April 11, 2016), the solar array energy production is 617 watt-hours with an atmospheric opacity (Tau) of 0.459 and a solar array dust factor of 0.785. Total odometry is 26.58 miles (42.78 kilometers), more than a marathon. __ Visit our Facebook page https://www.facebook.com/meteoritecentral and 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] Mars Rover Opportunity Update: March 30 - April 5, 2016
OPPORTUNITY UPDATE: Opportunity Captures Swirling Dust Devil at Endeavour Crater - sols 4331-4337, March 30, 2016-April 05, 2016: Opportunity is exploring the south side of 'Marathon Valley' located on the rim of Endeavour crater. The rover is up on the slopes of 'Knudsen Ridge.' The objective is to identify specific outcrops for evidence of clay minerals. Opportunity is conducting a mini-'walkabout' in regions that show evidence for clay minerals observed from orbit. The plan is to quickly survey a large region with imagery and then identify surface targets of interest for further in-situ (contact) investigation. At each drive location on the walkabout, the rover collects a 360-degree Navigation Camera (Navcam) panorama plus targeted multi-filter (color) Panoramic Camera (Pancam) panoramas. On Sol 4332 (March 31, 2016), Opportunity captured a Navcam image of a spectacular dust devil out in the interior of Endeavour crater, a rare sighting for Opportunity in Meridiani. Also on that sol, an Alpha Particle X-ray Spectrometer (APXS) performed a measurement of atmospheric argon. On the next sol, in addition to all the site survey imagery, the rover also collected documentary imagery of the Rock Abrasion Tool (RAT) bit to assess remaining grind capability. On Sol 4334 (April 2, 2016), the rover headed west with a 15.4-meter drive, collecting more Navcam and Pancam panoramas. On Sol 4337 (April 5, 2016) Opportunity turned southwest and drove about 15.5 meters in its walkabout with more imaging before and after the drive. As of Sol 4337 (April 5, 2016), the solar array energy production is 650 watt-hours with an atmospheric opacity (Tau) of 0.470 and a solar array dust factor of 0.817. __ Visit our Facebook page https://www.facebook.com/meteoritecentral and 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] Mars Rover Opportunity Update: March 23-29, 2016
OPPORTUNITY UPDATE: Climbing to Clay-Mineral Site Seen from Orbit - sols 4324-4330, March 23, 2016-March 29, 2016: Opportunity is exploring the south side of 'Marathon Valley' located on the rim of Endeavour crater. The rover is up on the slopes of 'Knudsen Ridge.' The objective is to identify specific outcrops for evidence of clay minerals. Opportunity has been driving towards high-slope regions that show evidence for clay minerals observed from orbit. With each drive the rover has bee collected extensive pre-drive and post-drive Panoramic Camera (Pancam) and Navigation Camera (Navcam) panoramas to document the terrain. On Sol 4325 (March 24, 2016), Opportunity drove west intending to cover about 49 feet (15 meters), but only achieved about 22 feet (6.8 meters). Visual Odometry (VO), which is used to track the rover's progress and direction, had difficulty converging on the featureless terrain around the rover. Visual Odometry works by tracking local surface features in the terrain as the rover moves. Another drive was sequenced on Sol 4328 (March 27, 2016), for about 79 feet (24 meters), but again the drive stopped after only 55 feet (16.9 meters) again due to lack of VO convergence on the featureless terrain. More progress was made on the next sol with a 22-foot (6.6-meter) drive to the southwest and on Sol 4330 (March 29, 2016), with a 43-foot (12.9-meter) drive also to the southwest. Opportunity is now believed to be in the area of the clay minerals seen from orbit. The rover is documenting the terrain with extensive Pancam color (multi-filter) panoramas. Energy levels have also improved markedly, a combination of improving solar insolation with season and dust cleaning events on the solar arrays. As of Sol 4330 (March 29, 2016), the solar array energy production has increased to 650 watt-hours with an atmospheric opacity (Tau) of 0.589 and an improved solar array dust factor of 0.857 (although this number may be affected by atmospheric clouds). Total odometry is 26.55 miles (42.74 kilometers), more than a marathon. __ Visit our Facebook page https://www.facebook.com/meteoritecentral and 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
