View Resource Evidence of Ancient Martian Life in Meteorite ALH84001?

This National Aeronautics and Space Administration website provides a summary of a study led by NASA's David McKay that may provide evidence for past life on Mars. McKay and his team found carbonate globule features on the ALH84001 meteorite that appear to be nanofossils. In addition, secondary mineral phases and hydrocarbons provide further evidence for past life. The website features color...

View Resource Magnetite Morphology and Life on Mars

This National Academy of Sciences scholarly paper discusses the strongest line of evidence for past life on Mars based on NASA's David McKay's original claims of finding nanofossils on the ALH84001 meteorite. This study concentrates on magnetite morphology, comparing morphologies of bacterial and abiotically produced magnetite. The findings are inconclusive, but do not strongly support evidence...

View Resource Exploring Meteorites Mysteries

This program allows educators to borrow meteorite samples and provides a teacher's guide with activities and a slide set to support lessons on the earliest history of the solar system and meteorite impacts on Earth. These educational materials may be borrowed as a package or the guide and/or slides are available separately.

View Resource The Zarkah Stone: The Park Forest Meteorite Case

This case study would be useful in a unit on meteors. It uses the example of a recent meteorite incident which occurred in Illinois to define exactly what a meteorite is (and the differences between the terms meteoroid, meteor and meteorite). The material would be appropriate for high school or lower level undergraduate students. The case study and teaching notes may be downloaded in PDF format....

View Resource A Photo Gallery of Meteorwrongs

This image gallery showcases more than 100 meteorwrongs (objects misidentified as meteorites). There are explanations of why the rocks probably are not meteorites and suggestions of what they most likely are and why. The site provides criteria for recognizing space objects and explains fusion crusts, regmaglypts, and other common features of meteorites.
