[meteorite-list] NASA's Next Mars Mission to Investigate Interior of Red Planet (InSight)
https://www.jpl.nasa.gov/news/news.php?feature=6934 NASA's Next Mars Mission to Investigate Interior of Red Planet Jet Propulsion Laboratory August 28, 2017 Preparation of NASA's next spacecraft to Mars, InSight, has ramped up this summer, on course for launch next May from Vandenberg Air Force Base in central California -- the first interplanetary launch in history from America's West Coast. Lockheed Martin Space Systems is assembling and testing the InSight spacecraft in a clean room facility near Denver. "Our team resumed system-level integration and test activities last month," said Stu Spath, spacecraft program manager at Lockheed Martin. "The lander is completed and instruments have been integrated onto it so that we can complete the final spacecraft testing including acoustics, instrument deployments and thermal balance tests." InSight is the first mission to focus on examining the deep interior of Mars. Information gathered will boost understanding of how all rocky planets formed, including Earth. "Because the interior of Mars has churned much less than Earth's in the past three billion years, Mars likely preserves evidence about rocky planets' infancy better than our home planet does," said InSight Principal Investigator Bruce Banerdt of NASA's Jet Propulsion Laboratory, Pasadena, California. He leads the international team that proposed the mission and won NASA selection in a competition with 27 other proposals for missions throughout the solar system. The long form of InSight's name is Interior Exploration using Seismic Investigations, Geodesy and Heat Transport. Whichever day the mission launches during a five-week period beginning May 5, 2018, navigators have charted the flight to reach Mars the Monday after Thanksgiving in 2018. The mission will place a stationary lander near Mars' equator. With two solar panels that unfold like paper fans, the lander spans about 20 feet (6 meters). Within weeks after the landing -- always a dramatic challenge on Mars -- InSight will use a robotic arm to place its two main instruments directly and permanently onto the Martian ground, an unprecedented set of activities on Mars. These two instruments are: -- A seismometer, supplied by France's space agency, CNES, with collaboration from the United States, the United Kingdom, Switzerland and Germany. Shielded from wind and with sensitivity fine enough to detect ground movements half the diameter of a hydrogen atom, it will record seismic waves from "marsquakes" or meteor impacts that reveal information about the planet's interior layers. -- A heat probe, designed to hammer itself to a depth of 10 feet (3 meters) or more and measure the amount of energy coming from the planet's deep interior. The heat probe is supplied by the German Aerospace Center, DLR, with the self-hammering mechanism from Poland. A third experiment will use radio transmissions between Mars and Earth to assess perturbations in how Mars rotates on its axis, which are clues about the size of the planet's core. The spacecraft's science payload also is on track for next year's launch. The mission's launch was originally planned for March 2016, but was called off due to a leak into a metal container designed to maintain near-vacuum conditions around the seismometer's main sensors. A redesigned vacuum vessel for the instrument has been built and tested, then combined with the instrument's other components and tested again. The full seismometer instrument was delivered to the Lockheed Martin spacecraft assembly facility in Colorado in July and has been installed on the lander. "We have fixed the problem we had two years ago, and we are eagerly preparing for launch," said InSight Project Manager Tom Hoffman, of JPL. The best planetary geometry for launches to Mars occurs during opportunities about 26 months apart and lasting only a few weeks. JPL, a division of Caltech in Pasadena, California, manages the InSight Project for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems, Denver, built the spacecraft. InSight is part of NASA's Discovery Program, which is managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. Together with two active NASA Mars rovers, three NASA Mars orbiters and a Mars rover being built for launch in 2020, InSight is part of a legacy of robotic exploration that is helping to lay the groundwork for sending humans to Mars in the 2030s.

[meteorite-list] Radar Reveals Two Moons Orbiting Asteroid Florence
https://cneos.jpl.nasa.gov/news/news199.html Radar Reveals Two Moons Orbiting Asteroid Florence Lance Benner, Shantanu Naidu, Marina Brozovic, and Paul Chodas Center for NEO Studies (CNEOS) September 1, 2017 Radar images of asteroid 3122 Florence obtained at the 70-meter antenna at NASA\u2019s Goldstone Deep Space Communications Complex between August 29 and September 1 have revealed that the asteroid has two small moons, and also confirmed that main asteroid Florence is about 4.5 km (2.8 miles) in size. Florence is only the third triple asteroid known in the near-Earth population out of more than 16,400 that have been discovered to date. All three near-Earth asteroid triples have been discovered with radar observations and Florence is the first seen since two moons were discovered around asteroid 1994 CC in June 2009. The sizes of the two moons are not yet well known, but they are probably between 100 - 300 meters (300-1000 feet) across. The times required for each moon to revolve around Florence are also not yet known precisely but appear to be roughly 8 hours for the inner moon and 22 to 27 hours for the outer moon. The inner moon of the Florence system has the shortest orbital period of any of the moons of the 60 near-Earth asteroids known to have moons. In the Goldstone radar images, which have a resolution of 75 meters, the moons are only a few pixels in extent and do not reveal any detail. Animated sequence of radar images of asteroid Florence obtained on Sep. 1, 2017 using the 70-m antenna at the Goldstone Deep Space Communications complex. The resolution of these images is about 75 meters. The images show two moons orbiting the much larger central body, which is about 4.5 km in diameter. The inner moon briefly disappears as it moves behind the central body and is hidden from the radar. (NASA/JPL).

The inner moon briefly disappears as it moves behind the central body and is hidden from the radar. (NASA/JPL). The radar images also provide our first close-up view of Florence itself. Although the asteroid is fairly round, it has a ridge along its equator, at least one large crater, two large flat regions, and numerous other small-scale topographic features. The images also confirm that Florence rotates once every 2.4 hours, a result that was determined previously from optical measurements of the asteroid\u2019s brightness variations. [Animation] The animated sequence to the left is built from a series of radar images of Florence. The sequence lasts several hours and shows more than two full rotations of the large, primary body. The moons can be clearly seen as they orbit the main body. Radar images are different from pictures taken with a digital camera but are similar to ultrasound images. The geometry in radar images is analogous to seeing an object from above its north pole with the illumination coming from the top. Projection effects can make the positions of Florence and its moons appear to overlap even though they are not touching. Florence reached its closest approach to Earth early on September 1 and is now slowly receding from our planet. Additional radar observations are scheduled at NASA\u2019s Goldstone Solar System Radar in California and at the National Science Foundation\u2019s Arecibo Observatory in Puerto Rico through September 8. These observations should show more surface detail on Florence and provide more precise estimates of the orbital periods of the two moons. Those results are valuable to scientists because they can be used to estimate the total mass and density of the asteroid. __ 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

Re: [meteorite-list] AD - Not All Lunar Meteorites Are Equal
David, Museums are not likely to want to test meteorites for authenticity for many reasons. First and foremost, doing so takes time away from research and classification of new material. Secondly, differentiating between two meteorites of the same classification is difficult if not impossible in some cases. If you just want to know if it is a meteorite and not terrestrial, there are people/companies that will perform that kind of work. Buying from trusted dealers is really important because sometimes that bargain may end up costing you much more than you may realize.

Re: [meteorite-list] AD - Not All Lunar Meteorites Are Equal
Thanks, Mike, I'd go even further in saying sadly 99% of the "meteorites" circulating freely in and from China are terrestrial rocks! The real Nantan meteorites in private collection are extremely rare, a total of around 40 kg. There is also a rarer type of meteorites intertwined with and inserted into earth rocks indicating high impact crushing/explosion. I'm happy to be proven wrong but as I said I have reasonable cause to believe my source to be reliable and genuine, although it's going to take me sometime to completely verify and document both types.
