Meanwhile, on the ground, an international team will prepare catalogs of the sources Akari detected, which will supersede the 20-year-old infrared Astronomical Satellite (IRAS) survey and provide rich target lists for new observatories such as the European Space Agency's soon-to-be-launched Herschel satellite (5&T: December 2006, page 30).
