Space Rocks Tell Their Secrets: Space Science Applications of Physics and Chemistry for High School and College Classes. Update.

As the scientific community studies Mars remotely for signs of life and uses Martian meteorites as its only available samples, teachers, students, and the general public continue to ask, "How do we know these meteorites are from Mars?" This question sets the stage for a six-lesson instructional package Space Rocks Tell Their Secrets. Expanding on the short answer "It's the chemistry of the rock", students are introduced to the research that reveals the true identities of the rocks. Since few high school or beginning college students have the opportunity to participate in this level of research, a slide presentation introduces them to the labs, samples, and people involved with the research. As they work through the lessons and interpret authentic data, students realize that the research is an application of two basic science concepts taught in the classroom, the electromagnetic spectrum and isotopes. Additional information is included in the original extended abstract.

Space Rocks Tell Their Secrets: Space Science Applications of Physics and Chemistry for High School and College Classes

As the scientific community studies Mars remotely for signs of life and uses Martian meteorites as its only available samples, teachers, students, and the general public continue to ask, "How do we know these meteorites are from Mars?" This question sets the stage for a three-lesson instructional package Space Rocks Tell Their Secrets. Expanding on the short answer "It's the chemistry of the rock", students are introduced to the research that reveals the true identities of the rocks. Since few high school or beginning college students have the opportunity to participate in this level of research, a slide presentation introduces them to the labs, samples, and people involved with the research. As they work through the lessons and interpret real data, students realize that the research is an application of basic science concepts they should know, the electromagnetic spectrum and isotopes. They can understand the results without knowing how to do the research or operate the instruments.

The DS1 hyper-extended mission

The Primary Mission for Deep Space (DS1) was to demonstrate 12 new technologies one of which was the Ion Propulsion System (IPS). After successfully completing its primary mission, DS1 was given a new mission. The objective of this Extended Mission was to fly by the Comet Borrelly. After the successful Borrelly encounter, the ion thruster on DS1 had to be operated for more than 14,000 hours in space. This provided a unique opportunity to investigate the condition of the thruster after long-term operation in space and determine, to the extent possible, if the thruster wear in space is consistent with that observed in long-duration ground tests.
