Directed by a collaboration of seven United States universities and NASA, the Antarctic Impulsive Transient Antenna (ANITA) is a "long duration balloon mission to constrain the origin of the highest energy particles in the universe." At this University of Hawaii at Manoa web site, users can download an informational proposal discussing the expected goals, scientific implementation, schedule, cost, and outreach. The web site presents project news, press releases, and images. The Science link offers an overview of the project as well as tutorials on neutrinos and cosmic rays. While a few links can only be obtained by the project's collaborators, users can find detailed summaries of ANITA at the site.
