[meteorite-list] Congratulations to Dr.Connelly
I have sent to Dr.Connelly many emails for the question of the Lido di Venezia meteorite seen we have sent all analysis months ago and not yet it was published in the met.bulletin, we have sent analysis of new NWA material and not yet it was published, and I not have received any answer. Congratulations for the reliability. The strange is the other NWA found from USA people immediatly they come published in few months. Is not a case is a little racism with european and above all with italian Researchers? If yes, well I hope in many fast time born a European Meteoritical Society so at least the ours business we can manage from here.

Re: [meteorite-list] Terrestrial meteorites on the Moon
This is what I thought but Sterling did some hunting around and produced some numbers that I checked. Now I'm not sure of my maths but is seems to be the case that an object can leave the earth and hit the moon with only its escape velocity. At that speed the impact prssures are not enough to vapourise the impactor so it is possible to find fragments of terrestrial meteorite on the moon, in theory --- On Thu, 5/8/08, E.P.

Re: [meteorite-list] Congratulations to Dr.Connelly
Matteo - Let me assure you that there is no bias as to whether US or European classifiers get some sort of preference on when meteorites get classified. We have had over 80 classifications ignored for long periods of time, some as long as 3 years. Recently, I have expressed my displeasure for the ineptness of those responsible (many have been replaced) and finally those 80 are being attended to. Be patient, things will get be better.

Re: [meteorite-list] Ordovician Meteorites...was New or maybe old
Hi Sterling, Elton, Just catching up with the mail here, as I have been out selling my book. Contra Muller and Morrison, the most likely injection mechanism is not a companion body but rather cometary impact due to gravitational fluctuation caused by our solar system passing through our galaxy. In this case most likely a cometary impact disrupted an asteroidal parent body, and we should be seeing signs of this in our samples, the L meteorites. We now have an estimated period for their condensation, gravitational differentiation within the parent body. We also gain a mechanism for setting the crater count clock throughout the solar system, and once the neutron and proton production are sorted out, and the percents and travel times to other bodies, a pretty good one.

http://www.guardian.co.uk/science/2008/may/07/starsgalaxiesandplanets.spaceexploration Closer encounter: Nasa plans landing on 40m-wide asteroid travelling at 28,000mph It was once considered the most dangerous object in the universe, heading for Earth with the explosive power of 84 Hiroshimas. Now an asteroid called 2000SG344, a lump of rock barely the size of a large yacht, is in the spotlight again, this time as a contender for the next giant leap for mankind. Nasa engineers have identified the 1.1m tonne asteroid, which in 2000 was given a significant chance of slamming into Earth, as a potential landing site for astronauts, ahead of the Bush administration's plans to venture deeper into the solar system with a crewed voyage to Mars. The mission - the first to what officials call a Near Earth Object (NEO) - is being floated within the US space agency as a crucial stepping stone to future space exploration. A report seen by the Guardian notes that by sending astronauts on a three-month journey to the hurtling asteroid, scientists believe they would learn more about the psychological effects of long-term missions and the risks of working in deep space, and it would allow astronauts to test kits to convert subsurface ice into drinking water, breathable oxygen and even hydrogen to top up rocket fuel. All of which would be invaluable before embarking on a two-year expedition to Mars. Under the Bush administration, Nasa has been charged with sending astronauts back to the moon, beginning in 2020 and culminating in a permanent lunar outpost, itself a jumping off point for more distant Mars missions. With the agency's ageing fleet of space shuttles due to be retired soon after 2010, the agency has begun work on a replacement called Orion and a series of Ares rockets that will blast them into orbit. In a study due to be published next month, engineers at Nasa's Johnson Space Centre in Houston and Ames Research Centre in California flesh out plans to use Orion for a three to six month round-trip to the asteroid, with astronauts spending a week or two on the rock's surface. As well as giving space officials a taste of more complex missions, samples taken from the rock could help scientists understand more about the birth of the solar system and how best to defend against asteroids that veer into Earth's path. An asteroid will one day be on a collision course with Earth. Doesn't it make sense, after going to the moon, to start learning more about them? Our study shows it makes perfect sense to do this soon after going back to the moon, said Rob Landis, an engineer at Johnson Space Centre and co-author of the report, which is due to be published in the journal Acta Astronautica. More precise measurements of the orbit of 2000SG344 have allayed fears that it could hit Earth sometime around the end of September 2030, but the asteroid is still expected to come close in astronomical terms. The report lays out plans for a crew of two to rendezvous with a speeding asteroid that is due to pass close by Earth. After a seven-week outward journey, the Orion capsule would swing around and close in on the rock. Because gravity is close to zero on asteroids, the capsule would need to attach itself, possibly by firing anchors into the surface. For the same reason, astronauts would not be able to walk around on the surface as they did on the moon. On some of these asteroids, you could jump up and go into orbit, or maybe even leave for good, said Landis. A round trip to an asteroid could be done with less fuel than a moon mission, but is technically very challenging. The asteroid is only 40 metres across and spins as it hurtles through space at 28,000mph. Landis thinks that a trip to an asteroid could capture imaginations even more than a return to our nearest celestial neighbour. When we head back to the moon, I think we'll see many of the same scenes we saw in the 60s and 70s Apollo programme. We've been to the moon, we got that T-shirt back in 1969. But whenever we've sent robotic probes to look at asteroids, we've always been surprised at what we've seen, he said. Because asteroids were forged in the earliest days of the solar system, analysing samples from them could shed light on the conditions that prevailed when the Earth was formed. Near Earth objects are a potential collision hazard to Earth and it may one day be necessary to deflect an asteroid from a collision course with Earth, said Ian Crawford, a planetary scientist at Birkbeck College, London. Having the capability in your back pocket to deflect an asteroid might be a good insurance policy for the future, and for that, you want to know what they are made of, how to rendezvous with them, and whether you risk getting hit by debris if you fire something at it. __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com
Re: [meteorite-list] Tectite (Tektite) ages
Hi Sterling, all - What we're seeing in regards to recent large iron impacts (Barringer, Alaska, and Siberia) is a rain of molten iron spherules. What we're seeing in regards to recent cometary impacts (at 10,900 BCE) is a rain of carbon spherules, containing high levels of 3He. Perhaps (once again, Perhaps) the reason for the identical dates for the tektites is an identical date for the parent body, which is what they are formed from, and not the age of the Earth's crust, as they are not formed from that material. But Elton can speak to large impact mechanics better than I can. E.P. Grondine Man and Impact in the Americas Be a better friend, newshound, and know-it-all with Yahoo! Mobile.

Re: [meteorite-list] Visit to a Small Planet
Dear Darren and List, Thank you Darren for the post. It seems to me that NASA should be more involved with studying and actively chasing meteorites, samples of different asteroids, here on Earth than worrying about going after samples of ONE asteroid; much more could be learned and at a much lower cost. NASA should set up a meteorite recovery team that travels the globe to recover new meteorite falls and discovery/detection systems that better detect their entry and fall locations, as well their space trajectories and origins. Orbits could be established and samples of a number of far away asteroids could be better understood. Currently we rely upon private citizens (meteorite hunters and astronomers) and a few scientists to do this and their personal budgets are much more limited and fall location information is often very hit-and-miss. If NASA wants to go somewhere, head to Mars full speed and don`t wait until 2030, 2050 or later.

Re: [meteorite-list] Terrestrial meteorites on the Moon
I believe that even a survivor of a fall to the surface of Luna will likely have been pulverized into regolith by the constant bombardment that reduces other moon rocks into lunar soil. Seems to me that the place to look is under the soil and under crater ejecta blankets and that will never be economical unless some sort of marker can be established to narrow the search. Time is not on the side of meteorite survival. What were the most recent cratering events on earth that was large enough to possibly eject target rock? Chesapeake? Reis? Chuxilub? Assuming a moderate transit time that is still several tens of millions of , years on the surface.

[meteorite-list] Phoenix Flying True Enough to Skip One Scheduled Adjustment
http://mars.jpl.nasa.gov/newsroom/pressreleases/20080509a.html Phoenix Flying True Enough to Skip One Scheduled Adjustment Jet Propulsion Laboratory May 09, 2008 NASA's Phoenix Mars Lander continues on course for its May 25 arrival at Mars. After targeting its certified landing site with a trajectory, or flight path, correction maneuver on April 10, the spacecraft's performance has been stable enough for the mission's operators to forgo the scheduled opportunity for an additional trajectory correction maneuver on May 10 and focus on the next such opportunity, on May 17. The Phoenix navigation team at NASA's Jet Propulsion Laboratory, Pasadena, Calif., made that recommendation after assessing the trajectory this week and mission management accepted the recommendation late Thursday. Phoenix has performed three flight path correction maneuvers since its Aug. 4, 2007, launch. Besides the May 17 one, the final opportunity for adjusting the course to hit the targeted landing area will be in the final 24 hours before landing. The first possible confirmation time for the spacecraft's landing on May 25 will be at 4:53 p.m. Pacific Daylight Time. The event would have happened 15 minutes and 20 seconds earlier on Mars, and then radio signals traveling at the speed of light will take 15 minutes and 20 seconds to cross the distance from Mars to Earth on that day. The Phoenix mission is led by Peter Smith of the University of Arizona, Tucson, with project management at JPL and development partnership at Lockheed Martin, Denver. International contributions are provided by the Canadian Space Agency; the University of Neuchatel, Switzerland; the universities of Copenhagen and Aarhus, Denmark; the Max Planck Institute, Germany; and the Finnish Meteorological Institute. ### Guy Webster 818-354-6278 Jet Propulsion Laboratory, Pasadena, Calif.

[meteorite-list] Intense Testing Paved Phoenix Road to Mars
http://mars.jpl.nasa.gov/spotlight/20080509_PHX.html Intense Testing Paved Phoenix Road to Mars Jet Propulsion Laboratory May 09, 2008 When NASA's Phoenix Mars Lander descends to the surface of the Red Planet on May 25, few will be watching as closely as the men and women who have spent years planning, analyzing and conducting tests to prepare for the dramatic and nerve-wracking event known as EDL - Entry, Descent and Landing. For after all their hard work, they know that landing on Mars is not a walk in the park. Less than 50 percent of all previous lander missions have made it safely to the surface. Like all missions, Phoenix was motivated by the potential science rewards. With its robotic arm, Phoenix will be the first mission to reach out and touch water ice in Mars' north polar region. The mission will study the history of the water in the ice, monitor weather of the polar region, and investigate whether the subsurface environment in the far-northern plains of Mars has ever been favorable for sustaining microbial life. Much of the Phoenix spacecraft already sat in secure storage when, in 2003, NASA selected it over other proposals to fly to Mars. Phoenix's main systems were designed and built for launch as the Mars Surveyor 2001 Lander, but that mission was canceled in February 2000, after the loss of a similar spacecraft, the Mars Polar Lander, during its arrival at Mars in 1999. The team that proposed the Phoenix mission, led by Peter Smith of the University of Arizona, Tucson, developed a plan to bring the spacecraft out of storage, thoroughly analyze and test it, resolve all known problems, and add upgrades so it could pursue a new set of science goals. The spacecraft heritage of the 2001 lander, derived from the faster, better, cheaper era, brought with it opportunities, along with several challenges. Phoenix Project Manager Barry Goldstein of NASA's Jet Propulsion Laboratory, Pasadena, Calif., discussed the team's approach to adapting a pre-built spacecraft for this mission, instead of developing one from scratch: One consequence of having so much of the hardware in place from the start was that we could focus our resources into testing and analysis. We evaluated the robustness of the vehicle to perform the mission we designed, most notably the entry, descent and landing. The team first focused on correcting all the vulnerabilities identified by earlier investigations into the loss of the Mars Polar Lander. That wasn't enough, Goldstein said. We eventually identified and mitigated more than a dozen other potential issues with the spacecraft that could have had dire consequences. Extensive testing and analysis also identified concerns that could have affected the lander, solar array deployment, and its science instruments after arrival on the Martian surface. However, an acceptable amount of risk still exists--for example, most hardware is at least 8 to 10 years old, and certain subsystems have no redundancy during the entry, descent and landing. Goldstein said, We've done everything we can to lower the risks of this mission to acceptable levels, but in no way does that mean we've eliminated all risk. Planetary exploration is risky by its very nature, and there are numerous challenges ahead of us, the first of which is entry, descent and landing. Here are descriptions of five examples of problematic hardware and resolutions resulting from the extensive work done by the Phoenix engineering and science team. Radar Phoenix uses a radar system initially designed as an altimeter for fighter jets. During the final minutes before landing, after the spacecraft has jettisoned its heat shield, Phoenix will rely on the radar for information about not just the altitude, but also the descent velocity and the horizontal velocity. The onboard computer will use that information several times per second to adjust the firing of 12 descent thrusters. Using the radar for this novel purpose required a tremendous amount of testing, We did more than 60 hours of flight testing, including 72 different drops at three sites with different geological characteristics, said David Skulsky, a JPL engineer on the Phoenix team. That's more radar flight testing than all previous NASA Mars missions combined. Radar tests also included custom-developed simulations of performance under Martian conditions. Running one of those simulator tests just four months before the spacecraft was due to be delivered to Florida for launch, Curtis Chen, a JPL radar engineer, noticed some strange behavior. Analysis confirmed that, under some circumstances, the radar could be confused by the jettisoned heat shield. JPL's Dara Sabahi, chief engineer for Phoenix, said, If this occurred in flight, the spacecraft would think it was much closer to the ground than it actually was. It would be a guaranteed failure. Once the testing had revealed the potential problem, engineers designed a relatively simple solution using adjustments related
