  Archeops, a balloon-borne experiment, will provide a measurement of CMB
anistropies from large to small angular scale thanks to its large sky coverage
(30%), its high angular resolution (10 arcminutes), and its high
signal-to-noise ratio due to high sensitivity 100 mK cooled bolometers. We will
therefore be able to put strong constraints on the value of the cosmological
parameters. Archeops flew already twice, once in Sicily for a technical flight
in 1999, and once from Sweden for its first scientific flight in January 2001.
I describe here Archeops'main characteristics, the preliminary results from the
scientific flight, the expected precision of this flight for power spectrum
measurements, and perspectives for the next flights this winter.
