Someone from the ESA has just let me know about about this nice use of WWJava called EOLi (Earth Observation Link). It is the European Space Agency’s client for Earth Observation Catalogue and Ordering Services.

Using EOLi, you can browse the metadata and preview images of Earth Observation data acquired by the satellites ENVISAT, ERS, Landsat, IKONOS, DMC, ALOS, SPOT, Kompsat, Proba, JERS, IRS, Nimbus, NOAA, SCISAT, SeaStar, Terra/Aqua.

EOLi is a standalone application that can run on Windows, Linux, UNIX and OSX the only requirement is the Java Runtime 1.5.

The EOLi website has detailed help files and tutorials on the use of the application.
