[meteorite-list] Curiosity Mars Rover Begins Study of Ridge Destination
https://www.jpl.nasa.gov/news/news.php?feature=6894 Curiosity Mars Rover Begins Study of Ridge Destination Jet Propulsion Laboratory July 11, 2017 The car-size NASA rover on a Martian mountain, Curiosity, has begun its long-anticipated study of an iron-bearing ridge forming a distinctive layer on the mountain's slope. Since before Curiosity's landing five years ago next month, this feature has been recognized as one of four unique terrains on lower Mount Sharp and therefore a key mission destination. Curiosity's science team informally named it "Vera Rubin Ridge" this year, commemorating astronomer Vera Cooper Rubin (1928-2016). "Our Vera Rubin Ridge campaign has begun," said Curiosity Project Scientist Ashwin Vasavada of NASA's Jet Propulsion Laboratory, Pasadena, California. "Curiosity is driving parallel to the ridge, below it, observing it from different angles as we work our way toward a safe route to the top of the ridge." A major appeal of the ridge is an iron-oxide mineral, hematite, which can form under wet conditions and reveal information about ancient environments. Hematite-bearing rocks elsewhere on Mars were the scientific basis for choosing the 2004 landing site of an older and still-active rover, Opportunity. Studies of Mount Sharp with the Compact Reconnaissance Imaging Spectrometer for Mars, on NASA's Mars Reconnaissance Orbiter, identified hematite in the ridge and also mapped water-related clay and sulfate minerals in layers just above it. Vera Rubin Ridge stands about eight stories tall, with a trough behind it where clay minerals await. Curiosity is now near the downhill face, which forms an impressive wall for much of the ridge's length of about 4 miles (6.5 kilometers). "In this first phase of the campaign, we're studying the sedimentary structures in the wall," said JPL's Abigail Fraeman, a Curiosity science-team member who helped plan these observations. This summer's investigations also seek information about the boundary zone between the material that makes up the ridge and the geological unit that Curiosity has been studying since late 2014: the Murray formation of lower Mount Sharp, which holds evidence of ancient lakes. The Murray formation has variable levels of hematite, but whether the hematite in it and in the ridge accumulated under similar environmental conditions is unknown. The planned ascent route will provide access to closer inspection of the hematite-bearing rocks. "We want to determine the relationship between the conditions that produced the hematite and the conditions under which the rock layers of the ridge were deposited," Fraeman said. "Were they deposited by wind, or in a lake, or some other setting? Did the hematite form while the sediments accumulated, or later, from fluids moving through the rock?" Deciphering the history of the ridge's hematite may shed light on whether the freshwater environments that deposited the layers of the older Murray formation were turning more acidic by the time the layers of the ridge formed. The mission also will be watching for clues about whether a gradient in oxidation levels was present, as that could have provided a potential energy source for microbial life. Terrain near the base of the ridge is rife with boulders and sand, creating challenging conditions for navigation, as well as opportunities to add to the mission's studies of sand dunes and ripples. The largest sand dunes were at lower elevations, including a linear dune informally named "Nathan Bridges Dune" in memory of Nathan Bridges (1966-2017), a Curiosity team member who helped lead the mission's dune studies. During the first year after its landing on Aug. 5, 2012, PDT (Aug. 6, EDT and Universal Time), the Curiosity mission accomplished a major goal by determining that billions of years ago, a Martian lake offered conditions that would have been favorable for microbial life. Curiosity has since traversed through a diversity of environments where both water and wind have left their imprint. The upcoming exploration of Vera Rubin Ridge and the higher clay and sulfate layers provides opportunities to learn even more about the history and habitability of ancient Mars. For more about Curiosity, visit: https://mars.jpl.nasa.gov/msl Status of Curiosity's Drill The rover team will not have Curiosity's rock sampling drill available in the first phase of studying "Vera Rubin Ridge." The drill feed mechanism, which moves the bit forward or back, faulted on Dec. 1, 2016, and no rocks have been drilled since then. While continuing to test possible ways to move the bit with the drill feed mechanism, rover engineers are also now studying alternative ways to drill. For the 15 rocks that Curiosity has sampled with its drill so far, two stabilizer posts, one to each side of the bit, were placed against the rock before the bit was extended with the feed mechanism.

[meteorite-list] Large Asteroid 3122 Florence to Safely Pass Earth on Sept. 1
https://www.jpl.nasa.gov/news/news.php?feature=6927 Large Asteroid to Safely Pass Earth on Sept. 1 Jet Propulsion Laboratory August 17, 2017 Asteroid Florence, a large near-Earth asteroid, will pass safely by Earth on Sept. 1, 2017, at a distance of about 4.4 million miles, (7.0 million kilometers, or about 18 Earth-Moon distances). Florence is among the largest near-Earth asteroids that are several miles in size; measurements from NASA's Spitzer Space Telescope and NEOWISE mission indicate it's about 2.7 miles (4.4 kilometers) in size. "While many known asteroids have passed by closer to Earth than Florence will on September 1, all of those were estimated to be smaller," said Paul Chodas, manager of NASA's Center for Near-Earth Object Studies (CNEOS) at the agency's Jet Propulsion Laboratory in Pasadena, California. "Florence is the largest asteroid to pass by our planet this close since the NASA program to detect and track near-Earth asteroids began." This relatively close encounter provides an opportunity for scientists to study this asteroid up close. Florence is expected to be an excellent target for ground-based radar observations. Radar imaging is planned at NASA's Goldstone Solar System Radar in California and at the National Science Foundation's Arecibo Observatory in Puerto Rico. The resulting radar images will show the real size of Florence and also could reveal surface details as small as about 30 feet (10 meters). Asteroid Florence was discovered by Schelte "Bobby" Bus at Siding Spring Observatory in Australia in March 1981. It is named in honor of Florence Nightingale (1820-1910), the founder of modern nursing. The 2017 encounter is the closest by this asteroid since 1890 and the closest it will ever be until after 2500. Florence will brighten to ninth magnitude in late August and early September, when it will be visible in small telescopes for several nights as it moves through the constellations Piscis Austrinus, Capricornus, Aquarius and Delphinus. Radar has been used to observe hundreds of asteroids. When these small, natural remnants of the formation of the solar system pass relatively close to Earth, deep space radar is a powerful technique for studying their sizes, shapes, rotation, surface features and roughness, and for more precise determination of their orbital path. JPL manages and operates NASA's Deep Space Network, including the Goldstone Solar System Radar, and hosts the Center for Near-Earth Object Studies for NASA's Near-Earth Object Observations Program, an element of the Planetary Defense Coordination Office within the agency's Science Mission Directorate.
