Chondrites give geologists insights on the makeup of the early solar system. Geologists are driven by understanding how the Earth came to be what it is today. Chondrites formed at the time o Introduction Chondrites are the most primitive rocks in the solar system. Chondrites are stony (non-metallic) meteorites that have not been modified due to melting or differentiation of the parent body. Chondrites are formed when dust and small grains that originated from the early solar system accreted to
The Classification and Main Types of Meteorites Many meteorites have been discovered over the years which, in many cases, can give an insight into the creation of the universe. All these meteorites can be grouped together by looking at the various characteristics they have in common, such as the structures of the different meteorites and the isotopic properties of the meteorites. When trying to classify meteorites, they are generally identified as one of the three main groups of meteorites: Iron
What are the different types of meteorites? The two main types of meteorites are primitive (chondrite) meteorites and processed (non-chondrite) meteorites. These two types are also further classified. Within the primitive meteorites are the stony primitive and carbon-rich primitive meteorites. Within the processed meteorites are also the classifications of metal-rich
experience. It is purely trial and error. Yet as earth’s orbit becomes more and more cluttered with damaged and outdated satellites threatening modern ones, space and orbit retrieval of objects may soon be a necessity. Again, carbonaceous chondrites could become useful, providing refueling for spacecraft carrying resources home. This way spacecraft would not have to carry fuel for the return trip on launch (remember they need a lot of fuel to carefully descend while carrying heavy resources)
INTRODUCTION The formation of Earth’s crust began during the Hadean eon, shortly after the Chaotian interval of core formation and solidification of the magma ocean (Allegre et al., 2008; Elkins-Tanton, 2008; Rudge et al., 2010). This process initiated with the differentiation of the crust-mantle zones from a bulk silicate Earth (BSE) reservoir, which is thought to have also produced the first continuous terrestrial crust (Allegre et al., 2008). However, whole rock signatures from original Hadean
Scientists have long wanted to understand the environment and composition of the mantle. Teams of geologist have been trying for years to drill boreholes into the mantle. However, due to today’s technology and dwindling knowledge, as we get deeper and deeper into Earth, no one has come remotely close to getting there. Despite the failed attempts to collect material from the mantle, there are other ways that the mantle can be studied. One way is to study minerals that we can expect to find in the

C-type, includes more than seven five percent of known asteroids: tremendously dark; similar to carbonaceous chondrite meteorites; approximately the same chemical arrangement as the Sun minus hydrogen, helium and other volatiles; S-type, seventeen percent: relatively bright; metallic nickel-iron assorted with iron- and magnesium-silicates; M-type, most of the rest:
must have been present for these PAH’s to be created. If we can prove Water did indeed exist on Mars then it is possible that life did exist on Mars. “The carbon isotopic compositions of ALH84001 are similar to those measured in CM2 carbonaceous chondrites. Consequently, the carbonates in ALH84001 and the CM2 meteorites are believed to have been formed by aqueous processes on parent bodies” (McKay et al, 1996, p.2) meaning that the rock found must have been formed within a lake bed or a
Space exploration should be funded at even greater levels than at present. It has provided scientific, technological, and economic benefits for all mankind. Furthermore it will continue to provide these benefits as long as we continue to explore. The American space program as well as the United States economy is facing many challenges at this time but we need to look at what the long term costs of not continuing a robust manned and unmanned space program will be. The solar system holds many mysteries
Are we alone in the universe? Is anything or anybody out there? These are age old questions, asked from people of all ages and races. But the first questions we need to ask are if it is even possible? Are there any other planets out there that are habitable? What does a planet need to be habitable? Without a habitable planet life cannot sustain in the universe, the search for life in the universe has been long and hard with no results proving life to exist outside of earth. The most predominant searchers
The ABC’s of Meteorite Collecting By Vincent S. Foster As Colby Navarro sat at his computer on March 26, 2003, he had no idea that a meteorite was about to come crashing through the roof of his Park Forest, Illinois, home, strike his printer, bounce off the wall, and land near a filing cabinet. The rock, about four inches wide, was part of a meteorite shower that swept through the Chicago area, damaging at least six houses and three cars. Scientists said that before the rock broke apart, it was probably
