Abstract
Cosmic Microwave Background observations became the tool
to probe the the first events of cosmic history. After WMAP data re-
leases, galactic and extragalactic foregrounds are perceived as the main
limiting uncertainty for the near-future search for the B-mode polar-
ization inprints from the inflationary era, either through satellites or
ground-based experiments like Brain at Dome-C. A combination of
technology, scanning strategy and above all, accurate knowledge of po-
larized foregrounds will be necessary for an optimal mapping of B-mode
CMB Polarization. In addition, the search for a better understanding
of the galactic foregrounds will provide unprecedented knowledge on
the Milky Way structure and star formation.
