I have arrived today from another field trip to recover the most recent Brazilian fall. I have solved to write this small report to let everybody know about this fall: This very interesting fall event occurred on a small district of Vicencia named Borracha. Vicência is a small city located about 120 km from Recife city, the capital of Pernambuco state in Brazil northwest. According to residents, Borracha interestingly received its name because it grew very fast stretching like rubber, that means Borracha in Portuguese. Mr. Adeilson was working in front of his modest joinery in Borracha village on a sunny Monday day of September, 21st. At a certain moment at around 3:00 PM he stooped to pick up something on the the ground and suddenly heard a very loud noise of something that had just hit the ground nearby him. He did not know what had happened but soon noticed a very strange black rock on a small pit only about 1 meter from him (he told us he measured the distance from where he was and the meteorite pit with a measuring tape and this can be seen on some youtube videos). Mr. Adeilson caught the almost hammer stone that could have killed him and noticed that one side of the rock was still hot and the other cold. Many neighbors were in front of their houses and witnessed the impact event noticing only the loud noise of the meteorite impact on the ground. As usual, nothing at impact zone was heard or seen in the air except the ground hit impact. One or two of them were just on the exact impact location very few minutes ago. I had just arrived home from another hard work day on Friday 27th and read some Internet hot news concerning a possible new meteorite fall in Brazil. According to these news only a meteorite could have caused such event. I immediately called Dr. Elizabete Zucolotto, meteorite researcher and curator of the Brazilian NM. She also read the news and there was no doubt that it could be a meteorite fall. We had to go to that location immediately. We bought the flight tickets to Recife at that same night and traveled the following day. Arriving at Recife we rented a car and headed to Vicência and then to Borracha village. On the way from Vicência city to the village we started to notice the mountains were covered with sugar cane and banana plantations and started to notice that finding more pieces of this fall could possibly be harder than Varre-sai. At least in Varre-sai there were some pastures to search. The entrance for the village is near an alcohol plant. Finding the village was also hard as there was no signs on the way and we had to ask to many people we found on the way. A lot of them were drunk and we thought that the sugar cane plantion were only for local usage.. The village is basically one road with houses on both sides and a small church. Interestingly the first person we have found on that village was Mr. Adeilson in front of his joinery that I have recognized by the videos and pictures. As hapenned in Varre-Sai with Mr. Germano, Mr Adeilson was already a famous person on that small village and had already given some interviews to TV channels and local radios. Fortunatelly the rock was still with him besides the fact that he had received many offers to sell but refused. The first lower offer he received was from a local resident that offered a new motorcycle. At fall location we made video interviews with Mr. Adeilson and some neighbors that witnessed the fall event. It was hard even for us that are Portuguese native to sometime understand what Mr. Adeilson said because of his strong accent. We then asked him if we could see the rock. He agreed and lead us to his modest house nearby the joinery. Holding the stone there was no doubt it was a beautiful super fresh meteorite that had fallen less than a week ago and was recovered still hot from the ground! We took pictures and talked to a lot of people that were in front of Mr. Adeilson's house attracted by the outer space visitor notice that spread like fire. There was no condition to try buying the stone at that moment and we decided to leave Mr. Adeilson's house and headed

[meteorite-list] 'The Atlas of Meteorites' - soon or never?
Dear list members, many of us have been waiting impatiently for more than three years for 'The Atlas of Meteorites' by M. Grady, G. Pratesi and V. Moggi Cecchi (9780521840354) to be published. The book description sounded very interesting. Unfortunately Cambridge University Press has been postponing the publishing date again and again and again Until recently it was supposed to be the 1st November 2013. There were no results matching your search. Now it has even disappeared from the website of Cambridge University Press, at Amazon it says Sign up to be notified when this item becomes available and the publication date has been reset to 24 March 2013. That doesn't sound very promising Is it still worth waiting or has the publication definitely been cancelled? Thanks in advance for any information that can shed some light on this matter!

[meteorite-list] LADEE Arrives At The Moon For Lunar Science Mission
http://www.spaceflightnow.com/minotaur/ladee/131006loi/ LADEE arrives at the moon for lunar science mission BY STEPHEN CLARK SPACEFLIGHT NOW October 6, 2013 NASA's LADEE spacecraft slipped into orbit around the moon Sunday, beginning a feverish four-month campaign to demonstrate a next-generation laser communications system and answer long-standing questions about the nature and origin of the tenuous lunar atmosphere. The modest Lunar Atmosphere and Dust Environment Explorer spacecraft, measuring about 7.7 feet tall and 4.7 feet in diameter, fired its liquid-fueled engine at 1057 GMT (6:57 a.m. EDT) for four minutes, allowing the moon's gravity to capture it into a high-altitude orbit over the equator. Controllers based at NASA's Ames Research Center in California - kept operating despite the partial shutdown of the federal government - oversaw the critical maneuver. NASA's public affairs personnel are furloughed by the budget impasse in Congress, but mission officials confirmed the orbit insertion maneuver occurred as planned. Radio ranging data will determine the orbit's exact parameters, but officials said LADEE's main engine fired for the expected duration, so the spacecraft should be in its planned orbit. Mission plans called for LADEE to enter a highly elliptical retrograde orbit taking the spacecraft around the moon approximately every 24 hours. Two major orbit adjust burns are planned Oct. 9 and Oct. 12 to lower the altitude of LADEE's orbit, ultimately reaching a near-circular orbit about 155 miles over the moon's equator. The orbit around the moon is retrograde, meaning opposite the lunar rotation, and also around the equator, said Greg Delroy, LADEE's deputy project scientist at Ames. A lot of the lunar science missions have done a polar orbit, but because of the kind of science we're after, we very much want to be around the equator. Sunday's arrival at the moon came after a one-month transit from Earth following LADEE's launch from Wallops Island, Va., aboard a Minotaur 5 rocket. LADEE completed three loops around Earth over the past month, aiming to arrive in the vicinity of the moon Sunday for the make-or-break orbit insertion burn. Once LADEE reaches the 155-mile-high orbit Oct. 12, ground teams will begin commissioning the probe's three science instruments, deploy aperture covers from the sensors, and activate the spacecraft's laser communications package for a 30-day demonstration of high-speed optical communications. The Lunar Laser Communications Demonstration aboard LADEE will link up with ground stations in New Mexico, California and the Canary Islands, exchanging data packets at speeds unattainable with radio communications systems. Once the two systems are locked and acquired, then we can send tens of megabits of data per second from the Earth up to the moon, and similarly we can send hundreds of megabits per second from the moon on LADEE down to the Earth, said Don Cornwell, the laser communication demonstration mission manager from NASA's Goddard Space Flight Center in Greenbelt, Md. Built by MIT Lincoln Laboratory, the communications payload will help build confidence for future missions to use laser data links from deep space, including NASA's manned asteroid mission and future rovers on the surface of Mars. NASA has a need for faster download speeds for data from space, Cornwell said. We'd like to be able to send high-resolution images, movies in 3D even, from satellites that not only orbit the Earth but also from probes that will go to the moon and beyond. Another benefit of laser communications is it requires fewer components and smaller terminals, both on the ground and in space. Light waves are shorter in wavelength than radio waves, so we can use smaller transmitters and receivers, Cornwell said. After LADEE's one-month commissioning and laser demo phase, controllers will put the probe in an orbit closer to the moon for a 100-day research mission exploring the dust environment just above the lunar surface and measuring the composition of the moon's ultra-thin atmosphere. The moon's atmosphere, or exosphere, is so thin its atoms never collide, according to Sarah Noble, LADEE's program scientist. Part of this mission is about redefining our understanding of space, Delroy said. The moon is part of a unique class of objects. They are solid rocky bodies, but they don't have a thick atmosphere around them. Other solar system bodies with exospheres like the moon include Mercury and giant asteroids like Ceres and Vesta, the destinations for NASA's Dawn mission. It's called a collisionless atmosphere, but it has many of the same behaviors as a typical atmosphere, Delroy said. There are winds in response to heat and light. There's a kind of lunar weather. LADEE's science instrumentation will study the dynamics of the lunar exosphere, measuring its response to sunlight, especially around the terminator
[meteorite-list] 60 Minutes: Eyeing the Sky For Danger
http://www.cbsnews.com/8301-18560_162-57606154/eyeing-the-sky-for-danger/ Eyeing the sky for danger 60 Minutes October 4, 2013 Though scientists are keeping an eye on most of the large asteroids and comets capable of causing global destruction by colliding with Earth, they have been able to track only one percent of the smaller ones that are capable of destroying an entire city, Anderson Cooper reports this Sunday on 60 Minutes. Cooper's story also reveals that NASA scientists first learned about the asteroid that exploded in Russia in February from Twitter and YouTube. There was no advance warning. We didn't see it coming, say Paul Chodas, a scientist at NASA's Jet Propulsion Laboratory in Pasadena, Calif. It was coming from the general direction of the sun, so it was in the daytime sky as it approached. Cooper's report will be broadcast on 60 Minutes Sunday, Oct. 6 at 7:30 p.m. ET/PT. The segment explores the scientific importance of near-Earth objects -- comets and asteroids whose orbits bring them close to the Earth -- as well as the difficulty scientists have detecting many of them. Scientists estimate there are over a million objects that come near Earth and are large enough to destroy an entire city. Ed Lu, a former astronaut, uses a computer representation of our solar system to show Cooper the 10,000 asteroids astronomers have found so far. It's just the tip of the iceberg, Lu says. We've only been able to observe a small fraction of the sky and we know that there are about 100 times more asteroids than we've found...about a million asteroids big enough to destroy a city out there, Lu tells Cooper. Paul Chodas and his boss Don Yeomans, manager of NASA's Near Earth Object Program Office, tell Cooper that asteroids capable of destroying a city are relatively small (over 40 yards wide) and are likely to land in uninhabited areas or in the ocean if they were to collide with Earth. That's why NASA has focused on finding the larger objects that could do much greater damage first and will then work its way down to the smaller ones, Chodas says. If astronomers find an object that is on a collision course with Earth many years in advance, then it would be possible to ram an unmanned spacecraft into the object and deflect it away from Earth, Yeomans and Chodas say. But it's impossible to deflect what you have yet to detect, which is why new tools may be needed. Former astronaut Ed Lu, who is now chairman and CEO of the B612 Foundation, is trying to raise private funds to build a space-based telescope that would use infrared sensors to detect near-Earth objects. Asteroids are often dark and difficult to detect in the inkiness of space, but an infrared telescope would notice the heat they emit, making them much easier to spot. I don't think there's any other... global-scale catastrophe that we can prevent...for the cost of building a freeway overpass, says Lu. Over long periods of time, Lu argues, the odds are high that there will be more impacts. He says it's like a game of cosmic roulette, but one that mankind cannot afford to lose. The phrase that they have in Vegas is that the house always wins, right? Lu tells Cooper. The sort of secret to all this is we're not the house. At some point...the solar system's going to get you. __ 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
