The Mars Polar Lander (MPL) launched in January and will land on the red
planet on December 3, 1999. The goal is to study the planet’s geology,
climate, and water to find out how Mars evolved, to learn about
relationships to Earth’s climate changes, and to look at resources for
future human exploration– ultimately to study the potential for life
elsewhere in the universe.

The Apple Learning Interchange is pleased to present a special feature
section dedicated to the Mars Polar Lander Mission. We have several
exciting resources for elementary, secondary and higher education faculty:

1.) ALI site is alive with special QuickTime broadcasts of the MPL
landing and the NASA events surrounding the landing. Tune in early to
test your QTV setup.

2.) We are featuring a section of pages dedicated to bringing this
current event into both K-12 and Higher Education classrooms. These pages
are filled with news & events, lesson plans, forums, projects, video
clips, and web reference materials to make educators virtual exploration
of Mars exciting.

3) We have created a special forum area for K12 and Higher Education
faculty as well as students to discuss and collaborate on issues
surrounding the event, space education in general and other topics.

Stay tuned throughout the school year for all things Mars on ALI!
