Rocks from Space- Further Reading
29 Aug 2013: Rocks from Space now available for iPad as an iBook.
8 Mar 2011: Unfortunately Space.com has decided to drop all archived articles - the following ones can no longer be found on their website. Please use the PDF links below or get the ebook.
During 1999 I was invited to write a series of articles about Near Earth Objects (NEOs - asteroids, comets and meteorites that occasionally visit the Earth's region of the solar system). With substantial help from Explorezone creator and editor Rob Britt, I have prepared several articles on a wide range of topics related to NEOs and more are planned. Explorezone is now associated with Space.com and these articles now appear on the Space.com website (no longer!)
2022 Note: I have moved many pages from tpg (or tpgi) to a new server. If a tpg link doesn't work please change
http://www1.tpgi.com.au/users/tps-seti/XXX.html to http://www.vdrsyd.com//planet/XXX.html
The PDFs require Adobe Acrobat Reader. They are copies of the Space.com web pages and are subject to copyright. They may be used for research and educational purposes with credit.
The following list provides further reading and web links for each of the articles. The references are aimed at a popular science level rather than an expert level. Suggestions for additional links are welcome.Other publications

Iron, nickel and other metals (including gold and platinum) were once finely dispersed throughout the primitive material from which Earth formed, but melting occurred early in Earth's history, and these metals settled for the most part into the core of the Earth. Only a small proportion of these metals can still be found in Earth's crust. On Eros, however, these metals would still be present, dispersed throughout the body of the asteroid. There have been serious suggestions that commercial mining of asteroids may someday become viable. While undifferentiated Eros may be 10% metallic nickel-iron by weight (with most of the iron in chemically bound forms), there are also differentiated asteroids, like 1986DA, that are almost pure nickel-iron.
